Description

Quick release structure of bicycle

technical field

The utility model relates to a bicycle accessory, in particular to a quick-release structure of a bicycle.

Background technique

In the past, the quick-release structure of bicycles was mostly of the pressing type, that is, the pressing handle and the pressed part were respectively set on the two rods to be assembled, and the two rods of the bicycle were connected by the pressing handle and the pressed part. , such as Taiwan patent application 090204992, the patent name is "quick release with safety device", which is the quick release structure of the pressing formula.

However, the quick release structure of the pressing type has the disadvantage of inconvenient assembly and disassembly, because when assembling, the pressing handle must first be snapped onto the pressed part, and then the pressing handle can be pulled to press the pressed part to assemble the two rods, disassemble Sometimes it is necessary to pull the tightening handle first to loosen the pressed part, and then to separate the two rods. It can be seen that at least two steps of engagement and pulling are required to disassemble and assemble. Now that everything is fast and convenient, it seems It's inconvenient.

Utility model content

The technical problem to be solved by the utility model is to provide a quick-disassembly structure of a bicycle, which can increase the speed of assembly and disassembly.

In order to solve the above-mentioned technical problems, the technical solution of the quick release structure of the utility model bicycle is:

Including the positioning column and the kit, the positioning column includes a cylinder, a spring and a stop piece, the cylinder includes a slot and a container, the slot is set at one end of the column, the slot has a limit surface, and the container is opened in the slot On the limit surface of the stop plate, the spring is accommodated in the slot, the stop piece is pivoted in the slot, and the stop piece is provided with a limit part and a positioning part, and the spring is pressed against the position part of the stop piece, so that the stop The piece rotates and its limiting part touches the limiting surface of the cutting groove, the positioning part protrudes from the side of the cylinder, and the corresponding positioning column of the kit is formed into a perforation;

The positioning post is provided with one end of the stop piece through the perforation of the kit. When the positioning post passes through the hole, the perforation will limit the positioning part of the stop piece, so that the stop piece rotates to retract the positioning part, allowing the positioning post to pass through At the same time, the positioning part of the stop piece will press against the spring in a state of accumulating force, and the limit part will break away from the limit surface of the slot. When the positioning post penetrates until the stop piece is out of the limit of the perforation, the spring will use its restoring force Push against the positioning part, so that the positioning part protrudes from the side of the cylinder, and then the positioning part can be used to limit the position of the positioning column and the kit for assembly and positioning;

The technical effect that the utility model can achieve is: as long as the positioning column penetrates the perforation of the kit, the positioning part of the stopper will automatically limit the positioning post and the kit, and when dismounting, as long as it is pressed against the stopper, the positioning post can It is separated from the kit, so the assembly and disassembly are quite easy and convenient.

Detailed ways

The quick release structure of the bicycle of the present invention is arranged on the two rod bodies B1 and B2 of the bicycle A, and its embodiment is shown in Fig. 1 to Fig. 4, including:

The positioning column 10 is arranged on the rod body B1. The positioning column 10, as shown in Figure 4, includes a column body 11, a spring 12 and a stopper piece 13; At one end, a limiting surface 111A is provided on the axial direction of the slot 111 , and two pivot holes 111B are provided opposite to the radial direction of the slot 111 . The spring 12 is housed in the container 112, the stop piece 13 is provided with a pivot hole 131, and the two pivot holes 111B of the slot 111 and the pivot hole 131 of the stop piece 13 are inserted with the pivot post 132, and the stop piece 13 Pivoted in the slot 111, the two sides of the stop piece 13 form a limiting portion 133 and a positioning portion 134, and the limiting portion 133 and the positioning portion 134 are respectively located on both sides of the pivot hole 131, wherein the positioning portion 134 is supported by a spring. 12 pushes against and makes the stop piece 13 rotate, and the stopper 134 then pushes against the stopper surface 111A of the notch 111, and the positioning part 134 protrudes from the side 113 of the cylinder 11; the utility model is also provided with a kit 20 , cooperate with the positioning column 10 to open a perforation 21 .

When assembling the two rod bodies B1 and B2 of the bicycle A, as shown in Figure 5, the rod body B2 is displaced in the direction of the rod body B1;

As shown in Figure 6 again, when the positioning column 10 of the rod body B1 passes through the perforation 21 of the sleeve 20 on the rod body B2, the perforation 21 will limit the positioning part 134 of the stop piece 13 on the positioning post 10, and push against the stop piece 13 to rotate to make the positioning Part 134 retracts, allowing positioning post 10 to pass through hole 21. At the same time, positioning part 134 will press against spring 12 with positioning surface 134A, so that spring 12 is in a power-storing state, and limiting part 133 is separated from limiting surface 111A of notch 111. ;

When the positioning column 10 penetrates until the stop piece 13 is free from the restriction of the perforation 21, as shown in FIG. Protruding from the side 113 of the column 11, the positioning part 134 can be stuck on the kit 20, and the positioning post 10 is limited in the kit 20, so as to assemble the two rods B1 and B2;

When the two rods B1 and B2 are disassembled, as shown in Figure 8, as long as force is applied to the stop piece 13, the stop piece 13 is rotated to retract the positioning part 134, and the positioning of the positioning post 10 and the sleeve 20 can be released;

As shown in Figure 9, the positioning column 10 is pulled out from the kit 20, and the two rods B1 and B2 can be disassembled and separated;

As can be seen from the foregoing, when the positioning post 10 penetrates the perforation 21 of the kit 20, the positioning portion 134 of the stop piece 13 will automatically limit the positioning post 10 and the kit 20, and thus assemble the two rods B1 and B2. Resisting the stop piece 13, the positioning post 10 and the sleeve 20 can be disengaged from the limit, and the two rods B1 and B2 can be disassembled, so the assembly and disassembly are quite fast. The utility model is used for a bicycle with a plug-in lock.
