Description

Directional fixed device

The present invention provides a directional fixing device, in particular, a fixing part of a base is inserted into a fixing hole of a preset first plate to form a fixation, and then the operation indicating structure of the sleeve is rotated to form an action in which the sleeve rotates but the base does not move, and the sliding member is driven to move along the guide ramp to the first positioning groove or the second positioning groove, so that the positioning body of the fixing member extends into or out of the fixing hole of the preset second plate to form a locking or unlocking action.

Generally, when assembling panels (board-to-board), they are locked using positioning screws with knobs, collars, and screws. The screws and collars are fixed to the first panel, and the knobs are rotated to lock the screws into the second panel to form a preset position. After the screws are tightened with hand tools, the first panel and the second panel are locked and fixed as one. It can be used for board-to-board connection on equipment composed of multiple devices and mechanisms, such as telecommunications cabinets, industrial computers, machine tools, or heat sinks.

However, since the components of the aforementioned devices or equipment are assembled and combined with each other by means of positioning screws, the surfaces of the components pressed by the heads of the screws are often damaged by the over-tightening of the screws, such as dents and cracks. In order to solve the problem of component damage caused by the aforementioned screw locking, some manufacturers also use welding to fix the components, but this design will make it difficult to disassemble some components of the industrial products after assembly, which will cause difficulties in repairing or replacing components.

Based on the above-mentioned shortcomings of the conventional directional fixed devices, it is necessary for those engaged in this industry to conduct research and development and improvement.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information and, after multiple evaluations and considerations, designed the invention of this directional fixing device.

The main purpose of the present invention is to provide a directional fixing device, comprising: a base, which includes a barrel, an annular portion and a channel; a sleeve, which has a accommodating cavity inside, and an operation indicating structure is formed on the top side of the sleeve, and the operation indicating structure is convexly provided with a directional convex portion toward one side, and at least one lifting structure is formed in a recessed manner inside the operation indicating structure, and the lifting structure is formed from top to bottom with at least one first positioning groove, a guide ramp and a second positioning groove located at the hollow part of the side wall of the sleeve; a fixing member, which includes a rod body and an elastic member is sleeved on the outside of the rod body, a through hole is provided on the top side of the rod body, and a positioning body is expanded outwardly at the bottom side of the rod body; a sliding member, which is penetrated and fixed in the through hole of the fixing member and at least one end is abutted against the second positioning groove to form positioning. By rotating the operation indicating structure of the sleeve as described above, the sleeve rotates but the base remains stationary, and the sliding member is driven to move along the guide ramp to the first positioning groove or the second positioning groove, so that the positioning body of the fixing member extends into or out of the fixing hole of the preset second plate to form a locking or unlocking action.

The secondary purpose of the present invention is to form two symmetrical tops on the barrel of the base for abutment of one end of the elastic member, and the two tops are formed with limiting surfaces on the inner sides corresponding to the positioning surfaces on the two sides of the rod of the fixing member, and the other end of the elastic member is abutted on a supporting portion formed by the top surface of the positioning body of the fixing member, and the barrel extends downward to expand to form the annular portion. The top surface of the annular portion forms an upper stop surface for the bottom side of the sleeve to abut against; and the bottom surface of the annular portion forms a lower stop surface for the upper surface of the preset first plate to contact, and the annular portion extends downward to form a fixing portion with a smaller diameter and penetrates the fixing hole of the preset first plate, and the outer wall of the fixing portion is cut to form an anti-rotation cutting edge to prevent the base and the preset first plate from rotating relative to each other.

Another purpose of the present invention is to form a rotation direction indicator and an unlocking image on the top surface of the operation indicator structure of the sleeve, and the sleeve is generally pentagonal in a top view, and the two side walls of the convex portion are concave to form a plurality of anti-slip grooves.

In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the present invention are described in detail in the following figure for the preferred embodiment of the present invention to fully understand its features and functions.

Please refer to Figures 1 to 4, which are the three-dimensional appearance diagram, three-dimensional exploded diagram, three-dimensional exploded diagram from another perspective and three-dimensional appearance diagram of the directional fixing device of the present invention. It can be clearly seen from the figures that the directional fixing device of the present invention mainly includes: a base 1, a sleeve 2, a fixing member 3 and a sliding member 4. All its components and features are described in detail as follows: The base 1 includes a barrel 11, an annular portion 12 and a fixing portion 13 for presetting the first plate and forming a channel 10 inside.

The sleeve 2 has a housing cavity 20 sleeved and positioned outside the barrel 11, and an operation indicator structure 21 is formed on the top of the sleeve 2. The operation indicator structure 21 has a convex portion 211 protruding toward one side, and at least one lifting structure 22 is formed in a recessed manner inside the operation indicator structure 21. The lifting structure 22 has at least one first positioning groove 222, a guide ramp 223 and a second positioning groove 224 located at the hollow part of the sleeve side wall from top to bottom.

The fixing member 3 includes a rod 31 inserted into the channel 10 of the base 1 and an elastic member 33 is sleeved on the outside of the rod 31. The top of the rod 31 is exposed to the second positioning groove 224 of the sleeve 2 and is provided with a through hole 310, and the bottom of the rod 31 expands outward to form a positioning body 32.

The sliding member 4 is fixed to the through hole 310 of the fixing member 3 and at least one end thereof is abutted against the second positioning groove 224 to form a positioning, and the operation indication structure 21 of the sleeve 2 is rotated to form an action in which the sleeve 2 rotates but the base 1 does not move, and the sliding member 4 is driven to move along the guide ramp 223 to the first positioning groove 222 or the second positioning groove 224, so that the positioning body 32 of the fixing member 3 extends into or out of the fixing hole 60 of the preset second plate 6 to form a locking or unlocking action.

Two symmetrical tops 111 are formed on the top of the barrel 11 of the base 1 and are used to abut one end of the elastic member 33. The two tops 111 have limiting surfaces 1111 formed on the inner sides thereof corresponding to the positioning surfaces 311 on the two sides of the rod 31 of the fixing member 3. The other end of the elastic member 33 abuts on a supporting portion 321 formed on the top surface of the positioning body 32 of the fixing member 3. The barrel 11 extends downward to expand to form the annular portion 12. The top surface of the annular portion 12 forms an upper stop surface 121 for the bottom side of the sleeve 2 to abut against; and the bottom surface of the annular portion 12 forms a lower stop surface 122 for the upper surface of the preset first plate 5 to contact, and the annular portion 12 extends downward to form the fixing portion 13 with a smaller diameter and penetrates the fixing hole 50 of the preset first plate 5, and the outer wall of the fixing portion 13 is cut to form an anti-rotation cutting edge 131 to prevent the base 1 and the preset first plate 5 from rotating relative to each other.

The top surface of the operation indicator structure 21 of the sleeve 2 is further formed with a rotation direction indicator 212 and an unlocking image 213, and the sleeve 2 is roughly pentagonal in a top view, and the two side walls of the directional protrusion 211 are concave to form a plurality of anti-slip grooves 214.

The preferred embodiment of the lifting structure 22 of the sleeve 2 is two, and has two symmetrical first limiting walls 221, two first positioning grooves 222, two guide ramps 223 and two second positioning grooves 224 from top to bottom, and the second positioning groove 224 is formed with a vertical second limiting wall 225 on the other side of the guide ramp 223, and the first limiting wall 221 can be used as a stop structure for the sliding member 4 to slide to the first positioning groove 222; and the second limiting wall 225 is used as a stop structure for the sliding member 4 to slide to the second positioning groove 224.

The sliding member 4 includes a shaft portion 41 in the shape of a rod, and a ratchet-shaped latch portion 42 is extended outward from the center of the shaft portion 41. The sliding member 4 is tightly fixed in the through hole 310 of the fixing member 3 through the latch portion 42.

When assembling the directional fixing device of the present invention, firstly, the barrel 11 of the base 1 is inserted into the receiving cavity 20 at the bottom side of the sleeve 2 to form a positioning, and the base 1 and the sleeve 2 can generate relative rotation, then the rod 31 of the fixing member 3 is inserted into the channel 10 of the base 1 and the rod 31 is exposed at the second positioning groove 224 of the sleeve 2, and then the sliding member 4 is inserted and fixed in the through hole 310 of the fixing member 3 and the latch part 42 is tightened and fixed, and the two ends of the shaft part 41 are held against the second positioning groove 224 to form a positioning, and the assembly of the directional fixing device is completed by the above.

Please refer to Figures 5 to 8, which are respectively a top view of the directional fixing device of the present invention and the two plates before locking, a cross-sectional side view before locking, a top view after locking, and a cross-sectional side view after locking, wherein the fixing portion 13 of the base 1 is first inserted into the fixing hole 50 of the first plate 5 to form a tight fixation, and the sliding member 4 is initially located in the first positioning groove 222 of the sleeve 2, and the sliding member 4 is located from a top view, parallel to the directional protrusion 211 of the sleeve 2 (as shown in Figure 5, but not limited to this), and the positioning body 32 of the fixing member 3 located below the sliding member 4 is completely received in the channel 10 of the base 1, and the elastic member 33 located outside the rod 31 is in a compressed state (as shown in Figure 6). When the first plate 5 and the second plate 6 are to be fixed, the operating indicator structure 21 is held to rotate the sleeve 2 but the base 1 is not moved, so as to drive the sliding member 4 to move downward from the first positioning groove 222 along the guide ramp 223 to the second positioning groove 224. Since the two limiting surfaces 1111 of the base 1 are held against the two positioning surfaces 311 of the fixing member 3, the fixing member 3 will not rotate with the sliding member 4. When the sliding member 4 is viewed from a top view, The locating body 32 of the fixing member 3 located below the sliding member 4 is perpendicular to the directional protrusion 211 of the sleeve 2 (as shown in FIG. 7, but not limited thereto), and extends downward from the outside of the base 1, so that the locating body 32 of the fixing member 3 extends into the fixing hole 60 of the second plate 6 to form a locking action, and at the same time, the elastic member 33 located outside the rod 31 is in an extended state (as shown in FIG. 8), and the locking action of the first plate 5 and the second plate 6 is completed by the above.

When the first plate 5 and the second plate 6 are to be unlocked, it is only necessary to hold the operation indicator structure 21 to rotate the sleeve 2 but keep the base 1 still, so as to drive the sliding member 4 to move upward from the second positioning groove 224 along the guide ramp 223 to the first positioning groove 222. At this time, the sliding member 4 turns from being perpendicular to the pointing protrusion 211 of the sleeve 2 to being parallel to the pointing protrusion 211 of the sleeve 2; the positioning body 32 of the fixing member 3 retracts from the fixing hole 60 of the second plate 6 into the channel 10 of the base 1, and at the same time, the elastic member 33 located outside the rod body 31 changes from an extended state to a compressed state, thereby completing the unlocking and separation actions of the first plate 5 and the second plate 6. The present invention enables the operator to quickly identify whether the directional fixing device is locked or unlocked by the alignment relationship between the sliding member 4 and the directional protrusion 211 of the sleeve 2, which helps to quickly operate when locking or disassembling two plates in large quantities.

The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present invention's specification and drawings should be included in the patent scope of the present invention and should be stated.

In summary, the directional fixing device of the present invention can achieve its effect and purpose when used. Therefore, the present invention is an invention with excellent practicality. In order to meet the application requirements of invention patent, the application is filed in accordance with the law. I hope that the review committee will approve this case as soon as possible to protect the inventor's hard work. If the review committee of the Jun Bureau has any doubts, please feel free to write to instruct. The inventor will do his best to cooperate and feel very grateful.
