Description

Tool type quick release structure

This creation is related to the parts of bicycles, more specifically, it refers to a tool-type quick release structure.

Press, the early bicycle quick release structure is mainly composed of a shaft, a nut screwed on one end of the shaft, and an eccentric lever pivoted on the other end of the shaft. The disadvantage of this structure is that when clamping, the eccentric lever is exposed and may be located in a non-upward position, which may be hit by foreign objects, resulting in damage or danger.

However, there is a quick-release device for bicycles, which is mainly composed of a shaft and a lever hidden in the shaft. When the shaft is to be rotated, the lever is pulled out for a length of time. , and is clamped with the shaft after bending, so as to drive the shaft to rotate, so as to achieve the effect of loosening or tightening the shaft. However, this kind of structure allows the lever to be hidden in the shaft at ordinary times, so as to prevent the lever from being hit by foreign objects. However, since the lever system cannot be completely separated from the shaft, the lever can only be used as a special tool for the shaft. However, since bicycles are composed of many parts, and many parts are combined by hexagonal screws, the riders (people) of the bicycles usually take extra six Angle wrench to facilitate the adjustment, assembly, disassembly, tightening or loosening of various parts on the way. If the parts in the quick release structure can also be used as tools that can be used by other parts in the bicycle, the bicycle riders (the public) do not need to carry extra tools to go out, so as to reduce the burden and improve the convenience.

In view of this, in order to improve the prior art, the quick release structure of the conventional bicycle has problems such as inability to apply to other parts and poor convenience. Therefore, the present invention provides a tool type quick release structure, which includes; a shaft rod , which has a shaft and a head coaxially connected to one end of the shaft, the outer diameter of the head is larger than the outer diameter of the shaft, and a shaft external thread is formed on the outer peripheral surface of the shaft. A built-in hole extends axially inwardly on the free end surface, and an embedding hole extends axially inwardly on the free end surface of the rod head, and the embedding hole has a non-circular cross-section; a tool rod has an embedding rod and a force application rod, one end of the insertion rod has a first insertion part, the first insertion part has a non-circular cross section, one end of the force application rod is pivotally connected with the other end of the insertion rod, and the force application rod can be opposite to each other The insertion rod pivots back and forth between an axial position and a radial position, and the other end of the force application rod has a holding portion. When the force application rod is in the axial position, the tool rod can penetrate the shaft The rod is stored in the built-in hole, and only the grip portion is exposed to the outside. When the tool rod is completely pulled out of the built-in hole under the action of external force, the first embedded portion can be inserted into the embedded hole. , the force lever can be pivoted from the axial position to the radial position; a limit unit is arranged on the outer peripheral surface of the force lever of the tool lever to prevent the tool lever from falling out when it is not affected by external force outside the built-in hole; thereby, the tool rod, which can be completely separated from the shaft, can be used as a tool for other parts to improve applicability and convenience.

Please refer to FIG. 1 to FIG. 3 , the limiting unit 50 is disposed on the force applying rod 32 of the tool rod 30 to prevent the tool rod 30 from self-propelled when the tool rod 30 is not subjected to external force. out of the inner hole 112 of the shaft 10 . The limiting unit 50 has an O-ring 51 and a conical surface 52; the O-ring 51 is sleeved on the ring groove 329 of the force-applying rod 32 of the tool rod 30, when the tool rod 30 is located in the built-in hole 112, the O-ring 51 abuts on the inner wall surface of the built-in hole 112 to prevent the tool rod 30 from falling out of the built-in hole 112; the conical surface 52 is formed on the tool rod 30 On the outer peripheral surface of the joint portion 326 of the gripping head 322, when the tool rod 30 is located in the built-in hole 112, the conical surface 52 abuts against the inner wall surface of the built-in hole 112 adjacent to the opening to prevent the tool rod 30 It comes out of the built-in hole 112 by itself.

Therefore, the above is the introduction of the components of the tool-type quick-release structure 100 and the assembling method thereof provided by a preferred embodiment of the present invention, and then its use characteristics are introduced as follows: First, as shown in FIG. 4, When using this creation (in order to avoid redundant description, the description of the wheel is omitted here), the shaft 11 of the shaft 10 of this creation is firstly worn. Pass through one fork rod 91 of a fork body 90 , then screw the external thread 111 of the rod body 11 with the other fork rod 91 , and rotate the shaft 10 slightly until the movable tightening ring 20 is on the The rough surface 22 is tightly abutted on the fork rod 91 . Since the smooth surface 21 of the movable tightening ring 20 faces the inner end surface of the club head 12 , when the rough surface 22 is pressed against the fork rod 91 , the smooth surface 21 will be in contact with the club head 12 . The inner end surface of the contact and sliding occurs, so that the movable tightening ring 20 will not rotate at this time, and it can ensure that the surface of the fork rod 91 will not be scratched by the rough surface 22 .

Then, the user can hold fingers on the grip pattern 328 of the exposed grip head 322 of the tool bar 30 and pull the entire tool bar 30 out of the built-in hole of the shaft 10 with a little force (as shown in Figure 5). Then, insert the tool rod 30 that has been detached from the shaft rod 10 and insert the first embedding portion 313 of the tool rod 30 into the embedding hole 121 of the shaft rod 10 (as shown in FIG. 6 ), Because the first embedding portion 313 and the embedding hole 121 have non-circular cross-sections, they can be connected and moved together. Then pivot the force application rod 32 of the tool rod 30 by 90 degrees to the radial position (as shown in Fig. 7), and then apply force to the force application rod 32 of the tool rod 30 to rotate (as shown in Fig. 8). shown in the figure), so that the shaft 10 can be screwed by the tool rod 30 . After being screwed, the first embedding portion 313 of the tool rod 30 can be separated from the embedding hole 121 of the shaft rod 10, and the tool rod 30 can be directed toward the built-in hole 112 of the shaft rod 10 (eg 9 ) to put the tool rod 30 into the built-in hole 112 of the shaft rod 10 again.

Of course, the tool rod 3 can not only be tightened when the shaft rod 10 is to be tightened 0 can be pulled out for use, and the tool rod 30 can also be pulled out for use when the shaft rod 10 is to be loosened. The tool rod 30 can also be directly pulled out for use when using the hexagonal wrench for other parts of the bicycle. In this way, the present invention can not only achieve the effect of burying the tool bar 30, but also because the tool bar 30 can be completely separated from the shaft bar 10, it can also be used as a tool for other parts, so that the applicability of the present invention is improved. It is greatly increased, and the convenience of use is increased, and the tools (weight) carried by the user when they go out to ride a bicycle can also be reduced, so as to reduce the burden on the user.

In addition, in the present invention, in addition to the first embedding portion 313 can be used. The second embedment portion 314 with an outer diameter smaller than the first embedment portion 313 can also be used as tools of different sizes, so as to enhance the application scope of the present invention.

The above disclosure is only a preferred embodiment provided by this creation, and is not intended to limit the scope of implementation of this creation. All the equivalent changes made by those skilled in the art according to this creation shall belong to this creation. scope of coverage.
