Quick release group anti-rotation structure

The creation department belongs to a positioning technology of a quick release group, specifically a quick release anti-rotation structure for preventing the trigger from rotating arbitrarily, thereby avoiding the arbitrarily rotating of the quick release group during use to ensure the trigger Positioning can further enhance the convenience of operation.

According to the telescopic pipe fittings, which are generally composed of inner and outer pipes, such as the seat cushion pipe of the bicycle and the seat pipe of the frame, in order to allow the inner and outer pipes of the telescopic pipe to be quickly released and adjusted after the telescopic adjustment is required, usually A quick release group is arranged at the end of the outer tube to operate the release and tightening positioning through the quick release group, and the existing quick release group is composed as shown in the first, second and third figures. The utility model is composed of a C-shaped collar (10) and a trigger (15). The C-shaped collar (10) has a locking seat (11) opposite to the perforation (110) at both ends, and two locking seats (11) There is a gap (12) between the two locking seats (11) of the C-shaped collar (10) after passing through a sleeve (13), and the trigger (15) One end has a cam block (16) having a straight pivoting groove (160) through which the bolt rod (14) is inserted, and a camming block (16) is further formed with a laterally penetrating eccentricity A shaft hole (161), the eccentric shaft hole (161) is provided for a shaft rod (17) screwed by the bolt rod (14) to the middle portion, so that the trigger rod (15) can be disposed through a gasket (18) On the lock seat (11) on the side of the C-beam (10), When the trigger (15) is pulled upward, the eccentric shaft hole (161) of the cam block (16) can be designed to change the gap (12) of the lock seat (11) at both ends of the C-beam (10). Large, and change the inner diameter of the C-shaped collar (10) to achieve the purpose of release. Conversely, when the trigger (15) is pressed, the C-type collar (10) can be pressed through the compression seat (11). ), making the inner diameter smaller to achieve the purpose of tightening; Although the above quick-release group can achieve the purpose of quickly releasing and tightening the telescopic tube, as shown in the first and fourth figures, the position of the trigger (15) mainly comes from the elastic tension of the C-type collar (10), but Easy to rotate due to external force when released [as shown in the fourth figure], once the trigger (15) is rotated, the cam block (16) is changed to the periphery of the surface of the lock seat (11) to make the trigger (15) It is impossible to pull the tightening downwards, and the trigger (15) must be reset again. If it is used on a bicycle, the inconvenience of the free operation, so how to ensure that the trigger (15) does not rotate arbitrarily. It is extremely important for the convenience of the quick release group. Therefore, how to avoid the above problems is the problem that the relevant industry is trying to improve.

In view of this, the creator has in-depth discussion on the positioning problem of the aforementioned quick-release group triggers, and actively pursues solutions through years of experience in R&D and manufacturing of related industries, and has been continuously researching and trialing, and finally Successfully developed a quick-release group anti-rotation structure, which can effectively overcome the troubles and inconvenience caused by the arbitrary rotation of the existing quick-release group trigger.

Therefore, the main purpose of this creation is to provide a quick-release group anti-rotation structure, so that the trigger of the quick-release group can be positioned to prevent the trigger from changing its position arbitrarily.

Moreover, another main purpose of this creation is to provide a quick release group. The anti-rotation structure, when applied to a bicycle, ensures that the position of the trigger does not change arbitrarily, thereby improving the convenience of operation.

Accordingly, this creation mainly achieves the aforementioned purposes and effects through the following technical means: it consists of a C-shaped collar, a bolt rod and a trigger for selectively tightening the pipe; The two ends of the type of collar have a relatively convex locking seat, and a gap is maintained between the two locking seats. The two locking seats respectively have a corresponding perforation for the bolt rod to be inserted, and the trigger is disposed on the bolt rod. a locking protrusion is formed on one end of the locking seat, and a positioning protrusion is formed at a center of the surface of the locking seat of the corresponding trigger, and the opposite end of the trigger has a cam block which can abut against the surface of the locking seat, and the cam block The utility model has a straight pivoting groove corresponding to the positioning latch of the clamping seat, and an eccentric shaft hole of the axis of the vertical bolt rod is formed on the cam block of the trigger, the eccentric shaft hole can be pivoted by a shaft, and the eccentric shaft hole can be pivoted The bolt rod end can be screwed to the middle portion of the shaft corresponding to the straight pivot slot.

Thereby, through the foregoing technical means, the quick disassembly anti-rotation structure of the present invention can use the pulling trigger to change the inner diameter of the C-shaped collar to provide the effect of releasing or tightening the telescopic tube, and A positioning protrusion is formed on the locking seat of the beam ring, and the positioning protrusion can be embedded in the straight pivoting groove of the trigger, so that the trigger is restricted without any left and right rotation relative to the C-shaped collar. Effectively ensuring its positioning, such as in the telescopic pipe fittings of bicycles, can improve the convenience of operation, and can improve its practicability, so it can greatly increase the added value of products, and improve the economic efficiency and competitiveness of products.

In order to enable the review board to further understand the composition, features and other purposes of the creation, the following is a preferred embodiment of the creation, together with the schema The detailed description will be followed by the implementation of the specification by those skilled in the art.
