As shown in fig. 1 and 2, a shock-absorbing foot nail includes a first base 1, a second base 2, an elastic member 3, a shock-transmitting pin 4, and a supporting foot 5. The elastic component 3 sets up in first base 1 and/or the second base 2, the upper end setting of biography shake is tied 4 is in on the first base 1, the lower extreme setting of biography shake is tied 4 is in on the second base 2, biography shake is tied 4 butt in on the elastic component 3. The supporting feet 5 are arranged below the second base seat 2.
On the one hand, the record player contacts the placing plane through the supporting legs 5 on the shock-absorbing legs, when the outside vibrates, the vibration can be conducted to the supporting legs 5 and then conducted to the second base 2, the shock-transmitting bolts 4, the elastic component 3 and the first base 1 in sequence. Since the shock-transmitting pin 4 abuts against the elastic member 3, the energy thereof is absorbed by the elastic member 3 and the shock-transmitting pin 4 during the shock transmission, and thus little or no shock affects the record player.
On the other hand, through a plurality of mutually independent subassemblies such as first base 1, second base 2, elastic component 3, shock-transmitting bolt 4 and supporting legs 5 constitute the foot nail of moving away to avoid possible earthquakes, such foot nail of moving away to avoid possible earthquakes can be better to isolating external vibrations. Even though the supporting leg 5 is affected to generate vibration, a plurality of components such as the second base seat 2, the vibration transmission bolt 4, the elastic component 3 and the first base seat 1 are indirectly arranged between the supporting leg 5 and the record player, and the vibration can be greatly lost in the process of transmitting among the components in turn, so that the vibration can be well isolated from the outside. If the shock-absorbing foot nail is composed of fewer components and even is a whole, the shock-absorbing foot nail cannot well isolate external shock.
Based on the two reasons, the shock-absorbing foot nail can prevent external shock from affecting the tone quality of the record player. After the shock-absorbing foot nails are arranged below the record player, the influence of external vibration on the tone quality of the record player can be effectively prevented, and the record player is facilitated to present better tone quality performance.
In the present invention, the elastic member 3 functions to absorb energy of vibration by deformation, thereby reducing the influence of external vibration on the jukebox. In the present invention, the elastic member 3 may be provided in the first base 1, the second base 2, or both the first base 1 and the second base 2 may be provided with the elastic member 3.
In the first embodiment, the elastic member 3 is provided in the first base chassis 1.
As shown in fig. 2, specifically, the first base 1 includes a first sleeve 11, a first base 12, an upper cover 13, and a lower cover 14; the first base 12 is arranged at the lower end of the inside of the first sleeve 11, a plurality of first mounting through holes for placing the elastic component 3 are formed in the first base 12, and internal threads are formed at the upper end of the first sleeve 11; the lower cover 14 is provided with external threads, the lower cover 14 is in threaded connection with the first sleeve 11, the lower surface of the lower cover 14 is abutted against the upper end surface of the elastic component 3 in the first base 12, and the upper end of the shock-transmitting bolt 4 is abutted against the lower end surface of the elastic component 3 in the first base 12; the upper cover 13 is provided with external threads, the upper cover 13 is in threaded connection with the first sleeve 11, and the upper cover 13 is located above the lower cover 14.
The first sleeve 11 has a cylindrical structure, and the first base 12 is integrally disposed at a lower end of the first sleeve 11. In order to set the elastic member 3 in the first base 1, the first base 12 is provided with a plurality of first mounting through holes for placing the elastic member 3. When in assembly, firstly, the shock-transmitting bolt 4 is placed in the first mounting through hole, and then the elastic component 3 is placed in the first mounting through hole; after each first installation through hole is operated in this way, the lower cover body 14 is screwed into the upper end of the first sleeve 11 through threaded connection, so that the lower surface of the lower cover body 14 is abutted against the upper end face of the elastic component 3 in the first base 12, at this time, the lower end face of the elastic component 3 in the first base 12 is abutted against the upper end of the shock-transmitting bolt 4, and the lower end of the shock-transmitting bolt 4 passes through the first installation through hole and is exposed below the first base 1. It should be noted that, the elastic component 3 applicable to the first mounting through hole is a spring or an elastic ball, and if the elastic component 3 adopts an elastic washer, a corresponding annular groove needs to be provided.
The upper cover 13 and the lower cover 14 are both provided at the upper end of the first sleeve 11 by being screwed with the internal thread of the upper end of the first sleeve 11. The upper cover 13 is connected with the record player, and the shock-absorbing foot nails are arranged on the record player through the upper cover 13; specifically, a threaded hole may be formed on the upper surface of the upper cover 13, and after the bolt passes through the relevant connection structure on the record player, the shock-absorbing foot nail may be set on the record player by matching with the threaded hole on the upper surface of the upper cover 13. The lower cover 14 is used for fixing the elastic component 3 in the first mounting through hole, so that the elastic component 3 is respectively abutted against the lower cover 14 and the shock-transmitting bolt 4 to play a role of absorbing shock.
The length of the internal thread of the upper end of the first sleeve 11 is greater than the sum of the thicknesses of the upper cover 13 and the lower cover 14. Therefore, after the lower cover 14 is mounted and fixed on the first sleeve 11, the upper cover 13 also has a certain space to be lifted or lowered. This has the advantage that the level of the record player can be adjusted by adjusting the degree of engagement of the upper cover 13 with the upper end of the first sleeve 11. For example, when the shock-absorbing pins are too high, the upper cover 13 may be screwed more into the upper end of the first sleeve 11 so that the upper cover 13 is lowered, and the height of the shock-absorbing pins is lowered by lowering the height of the upper cover 13, thereby adjusting the level of the record player; when the shock-absorbing foot nails are too low, the upper cover 13 can be screwed out of the upper end of the first sleeve 11 more, so that the upper cover 13 is lifted, the height of the shock-absorbing foot nails is lifted by lifting the height of the upper cover 13, and the level of the record player is adjusted.

After the shock-transmitting bolt 4 is placed in the first mounting through hole, the column body 42 passes through the first mounting through hole, but the lower surface of the first cap body 41 is abutted on the limiting table in the first mounting through hole, so that the shock-transmitting bolt 4 can be arranged in the first mounting through hole.
As shown in fig. 4, in order to realize connection between the shock-transmitting pin 4 and the second base 2, an external thread is provided at the lower end of the cylinder 42, a plurality of internal thread holes are provided on the upper surface of the second base 2, and the shock-transmitting pin 4 is disposed on the second base 2 by being screwed with the internal thread holes on the second base 2. As described above, the lower end of the shock-transmitting pin 4 passes through the first mounting hole and is exposed below the first base 12, so that the connection between the shock-transmitting pin 4 and the second base 2 can be achieved only by screwing the lower end of the column 42 into the internal threaded hole of the second base 2.
When the shock-absorbing foot nail in the first embodiment specifically works, on one hand, when the outside is shocked, the shocking is conducted to the supporting feet 5, and then is conducted to the second base seat 2 by the supporting feet 5, and the second base seat 2 conducts the shocking to the elastic component 3 through the shock-absorbing bolts 4, and at the moment, the elastic component 3 absorbs most of energy of the shocking; on the other hand, since the components are independent of each other, vibration is difficult to be transmitted and diffused between the components, thereby isolating external vibration.
In the second embodiment, the elastic member 3 is provided in the first base chassis 1 and the second base chassis 2. In the second embodiment, most of the structure of the first base 1 is the same as that in the first embodiment, and therefore, a description will not be given in detail regarding this structure and the working principle, and reference is made to the above description, and only the structure different from that in the first embodiment will be described below.
As shown in fig. 3, the shock-transmitting pin 4 includes a second cap 43 provided at the lower end of the column 42, in addition to the first cap 41. Similar to the first cap 41, the second cap 43 functions to enable the shock-transmitting pins 4 to be disposed on the second base plate 2.
The second base 2 comprises a second sleeve 21, a second base table and a bottom cover body 22; the second base is arranged at the upper end of the interior of the second sleeve 21, a plurality of second mounting through holes for placing the elastic component 3 are formed in the second base, and internal threads are formed at the lower end of the second sleeve 21; the bottom cover 22 is provided with external threads, the bottom cover 22 is in threaded connection with the second sleeve 21, the upper surface of the bottom cover 22 abuts against the lower end surface of the elastic component 3 in the second base, and the second cap 43 abuts against the upper end surface of the elastic component 3 in the second base. In addition, in order to enable the shock-transmitting pin 4 to be arranged in the second mounting through hole, a limiting table is arranged in the second mounting through hole.
The second sleeve 21 is a cylindrical structure, and the second base is integrally disposed at an upper end of the inside of the second sleeve 21, and in order to dispose the elastic component 3 in the second base 2, the second base is provided with a plurality of second mounting through holes for placing the elastic component 3. When in assembly, firstly, the shock-transmitting bolt 4 is placed in the second mounting through hole, and then the elastic component 3 is placed in the second mounting through hole; after each second installation through hole is operated in this way, the lower end of the second sleeve 21 is screwed into the bottom cover body 22 through threaded connection, so that the upper surface of the bottom cover body 22 is abutted against the lower end face of the elastic component 3 in the second base, at this time, the upper end face of the elastic component 3 in the second base is abutted against the lower end of the shock-transmitting bolt 4, and the upper end of the shock-transmitting bolt 4 passes through the second installation through hole and is exposed above the second base 2.
The first cap 41 and the second cap 43 are respectively provided at the upper and lower ends of the column 42 on the shock-transmitting pin 4. In order to install the shock-transmitting bolt 4 into the first installation through hole and the second installation through hole, the first cap 41 is abutted against the limiting platform in the first installation through hole, the second cap 43 is abutted against the limiting platform in the second installation through hole, the shock-transmitting bolt 4 comprises two bolts and an internal thread sleeve, the two bolts are installed into the internal thread sleeve from two ends to form the complete shock-transmitting bolt 4, at the moment, nuts of the two bolts are the first cap 41 and the second cap 43 respectively, and the internal thread sleeve is a cylinder 42.

Specifically, the conical base 23 is provided with external threads, and the conical base 23 is also provided at the lower end of the second sleeve 21 through threaded connection, as is the bottom cover body 22. In the first embodiment, the conical base 23 is integrally provided on the second base 2.
When the shock-absorbing foot nail in the second embodiment specifically works, on one hand, when the outside is shocked, the shock is conducted to the supporting leg 5, and then is conducted to the conical base 23 by the supporting leg 5, the elastic component 3 in the second base 2 absorbs the shocked energy for the first time, and then the shock-absorbing bolt 4 and the elastic component 3 in the second base 2 absorb the shocked energy for the second time. Compared with the shock-absorbing foot nail in the first embodiment, the shock-absorbing foot nail in the second embodiment has better shock-absorbing effect due to the fact that the shock-absorbing energy is absorbed twice; on the other hand, since the components are independent of each other, vibration is difficult to be transmitted and diffused between the components, thereby isolating external vibration.
In the third embodiment, the elastic member 3 is provided in the second base plate 2. It will be appreciated that in the third embodiment, the structure and operation principle of the second base 2 are the same as those of the first embodiment, but the first embodiment is replaced with the same, and therefore, the third embodiment will not be described in detail, and reference may be made to descriptions of the first embodiment and the second embodiment.
The elastic component 3 in the invention can be arranged on the first base 1 and/or the second base 2 to effectively absorb the energy of vibration, thereby preventing the external vibration from affecting the tone quality of the record player.

As shown in FIG. 5, the lower end of the shock absorbing foot pin is integrally formed with a tapered structure. If the lower end of the shock-absorbing foot nail is of a plane structure, the contact area between the shock-absorbing foot nail and the placing plane is large, and external vibration is easily transmitted into the record player through the shock-absorbing foot nail; after the conical base 23 is arranged on the lower surface of the second base 2 and the supporting legs 5 are arranged on the tip end of the conical base 23, the lower ends of the shock-absorbing foot nails integrally form a conical structure, the contact area between the shock-absorbing foot nails and the placing plane is reduced to the minimum, and external vibration can be prevented from being transmitted into the record player through the shock-absorbing foot nails.
Because the lower extreme of the shock-absorbing foot nail integrally forms a conical structure, the lower the strength, the more easily damage appears, and when the conical structure damages, the record player can not be stably placed on a placing plane, and the shock-absorbing function can not be realized.
When the second base 2 is configured as a unitary structure, if the conical structure is damaged, the second base cannot be used normally unless the entire conical base 23 is replaced integrally, but this would make the maintenance cost too high.
Preferably, the conical base 23 is integrally arranged below the second base 2, and a supporting leg installation through hole penetrating through the tip of the conical base 23 along the up-down direction is formed, the supporting leg 5 is detachably arranged in the supporting leg installation through hole through a fixing bolt, and when the supporting leg 5 is damaged, replacement and repair can be carried out at extremely low cost, so that the shock-absorbing foot nail realizes the shock-absorbing function again. Meanwhile, the conical base 23 and the supporting legs 5 can be divided into two mutually independent components in such a way, and the vibration isolation effect can be improved.
Furthermore, the conical base 23 and the supporting legs 5 are made of different materials, and resonance between the conical base 23 and the supporting legs 5 is avoided to influence the tone quality of the record player due to different natural frequencies of the different materials. Specifically, the conical base 23 is made of aluminum alloy, and the supporting leg 5 is made of stainless steel. Similarly, since the first base 1 and the second base 2 are connected by the shock-transmitting bolt 4, in order to prevent resonance between the first base 1, the shock-transmitting bolt 4 and the second base 2, the material of the shock-transmitting bolt 4 is different from the material of the first base 1 and the material of the second base, specifically, the material of the first base 1, the material of the second base 2, the material of the upper cover 13, the material of the lower cover 14 and the material of the bottom plate cover are aluminum alloy, the material of the shock-transmitting bolt 4 is teflon, and the material of the supporting leg 5 is stainless steel.
It should be noted that, the first base 1, the second base 2 and the conical base 23 are solid structures, so that the quality of the shock-absorbing foot nail can be greatly increased, and the shock-absorbing effect of the shock-absorbing foot nail is improved. It can be understood that if each component forming the shock-absorbing foot nail is of a hollow structure, the overall mass of the shock-absorbing foot nail is smaller, and at this time, if the outside vibrates, the shock-absorbing foot nail vibrates with the outside vibration to a larger extent; if each component forming the shock-absorbing foot nail is of a solid structure, the shock-absorbing foot nail has larger overall mass, and is relatively not easy to be affected even if the outside is vibrated.
In order to realize the detachable connection of the supporting leg 5, specifically, a supporting leg installation through hole penetrating through the tip of the conical base 23 along the up-down direction is formed in the second base 2, and a limiting table is arranged in the supporting leg installation through hole; the supporting leg 5 comprises a cylindrical part 51 and a conical part 52, the conical part 52 is arranged at the lower end of the cylindrical part 51, and an internal threaded hole is formed in the cylindrical part 51; the support leg mounting through hole is internally provided with a fixing bolt, a nut of the fixing bolt is abutted to a limiting table in the support leg mounting through hole, and a threaded portion of the fixing bolt is in threaded connection with an internal threaded hole in the cylindrical portion 51.
During specific installation, the supporting legs 5 are preset in the supporting leg installation through holes from bottom to top, then the fixing bolts are placed into the supporting leg installation through holes from top to bottom, and then the fixing bolts are rotated, so that the threaded parts of the fixing bolts are in threaded connection with the internal threaded holes in the cylindrical parts 51 until the nuts of the fixing bolts are abutted to the limiting tables in the supporting leg installation through holes, and at the moment, the supporting legs 5 are completely and fixedly installed below the second base 2.
In particular, the elastic member 3 is a spring or an elastic ball or an elastic washer in order to absorb vibration energy; more specifically, the elastic ball may be a silica gel ball, or may be made of other elastic materials, which is not limited in the present invention. The energy of external vibration can be absorbed through the deformation of the spring or the elastic ball or the elastic washer, and the influence of the external vibration on the tone quality of the record player is prevented.
When the elastic component 3 is a spring or an elastic ball, 3-8 elastic components 3 are arranged. If the springs or the elastic balls are only provided with 1 or 2, the elastic component 3 can only concentrate on one or two points to bear force, so that on one hand, the balance is difficult to realize, and on the other hand, the shock absorbing effect is poor, and therefore, the 3-8 springs or the elastic balls are provided as the elastic component 3, and the shock absorbing effect can be ensured while the balance is kept. As for the specific number, the electric gramophone can be adjusted according to the actual situation of the electric gramophone, if the whole volume and the mass of the electric gramophone are larger, the volume and the mass of the shock-absorbing foot nails are also larger, and at the moment, 6, 7 or 8 springs or elastic balls can be arranged; if the overall volume and mass of the record player are small, the volume and mass of the shock-absorbing peg are also small, and 3, 4 or 5 springs or elastic balls can be arranged at the moment. Of course, when the elastic members 3 are elastic washers, 1 elastic member 3 is provided.
In summary, the present invention provides a shock-absorbing foot peg for a record player, an audio device, etc., which is mainly configured to absorb shock through an elastic component 3 and each component independent of each other, on one hand, the record player contacts a placement plane through a supporting leg 5 on the shock-absorbing foot peg, and when external shock occurs, the shock is transmitted to the supporting leg 5, and then is transmitted to a second base 2, a shock-transmitting bolt 4, the elastic component 3 and a first base 1 in sequence. Since the shock-transmitting pin 4 abuts against the elastic member 3, the energy thereof is absorbed by the elastic member 3 and the shock-transmitting pin 4 during the shock transmission, and thus little or no shock affects the record player. On the other hand, through a plurality of mutually independent subassemblies such as first base 1, second base 2, elastic component 3, shock-transmitting bolt 4 and supporting legs 5 constitute the foot nail of moving away to avoid possible earthquakes, such foot nail of moving away to avoid possible earthquakes can be better to isolating external vibrations. Even though the supporting leg 5 is affected to generate vibration, a plurality of components such as the second base seat 2, the vibration transmission bolt 4, the elastic component 3 and the first base seat 1 are indirectly arranged between the supporting leg 5 and the record player, and the vibration can be greatly lost in the process of transmitting among the components in turn, so that the vibration can be well isolated from the outside. If the shock-absorbing foot nail is composed of fewer components, even if the shock-absorbing foot nail is a whole, the external shock cannot be well isolated.
It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
