A bicycle brake clamp is composed of a copper sleeve, a shaft sleeve, a sleeve cover, a spring body, an adjusting seat and a combining sleeve which are combined in a shaft hole position at the bottom of a brake body, and a bolt and a gasket are arranged in a screw hole of a protruding shaft of a bicycle frame in a penetrating and screwing mode for positioning; the sleeve cover, the spring body and the adjusting seat are limited into a whole by the shaft sleeve and the combination sleeve, a protruding ring is arranged in the inner wall of a through hole of the combination sleeve to be embedded into a ring groove arranged on the surface of the edge end of the shaft sleeve to form a limiting state, and then the other edge end of the shaft sleeve is sleeved into the through hole of the copper sleeve and slightly protrudes out of the shaft hole of the brake body to be tightly combined with a gasket; therefore, the sleeve cover, the spring body and the adjusting seat are combined into a whole through the shaft sleeve and the combination sleeve, and the practical effect that an assembler can quickly and directly install the spring body on the frame can be provided.

Description

bicycle brake caliper

technical field

The utility model relates to a bicycle structure, in particular to a bicycle brake caliper.

Background technique

There are many creations related to the development of brakes in bicycles, which are nothing more than emphasizing the effect of adjustable braking effect, but the applicant found in the actual assembly operation that: due to the large number of components to be assembled and the small size of the brake caliper, it is difficult to make the brake caliper. It takes a lot of time to assemble. For example, when the entire brake caliper is assembled on the frame, the copper sleeve B is first assembled in the shaft hole A1 of the caliper body A, and then the spring rod C is placed on the outside of the adjustment seat D , and then put the adjustment seat D in the protruding shaft F1 of the frame F, then put the caliper body A into the adjustment seat D through the copper sleeve B, and finally put a washer E' and the bolt E through After the body A of the caliper, the copper sleeve B, the spring rod C, and the adjustment seat D, screw it into the screw hole F2 of the protruding shaft F1 of the frame F for positioning (as shown in Figure 1). Such a shape seems simple, but it cannot be assembled quickly, especially when the extended seat D1 of the adjustment seat D itself is assembled into the inner wall of the copper sleeve B, it is not easy to embed it, so it takes some time. In addition, there are other car body components during assembly, and there is not a very spacious space for use in assembly, all of which lead to troubles in assembly.

Therefore, the applicant then develops a brake caliper creation with convenient assembly in view of the above problems, thinking that the manufacturer can quickly assemble it into one body when it is shipped, so that there will be no missing components. When delivered to the assembler, the whole group can also be installed conveniently and directly, and then the application for this patent is proposed.

Contents of the invention

The purpose of the utility model is to provide a bicycle brake caliper to overcome the defects of the above-mentioned traditional structure, so that the assembler can quickly and directly install it on the frame.

According to the above purpose, a bicycle brake caliper is combined with a copper sleeve, a shaft sleeve, a sleeve cover, a spring body, an adjustment seat and a coupling sleeve in the shaft hole position at the bottom of the brake body, and then inserted through a bolt with a washer. And screwed in the screw hole of the protruding shaft of the frame; it is characterized in that: the sleeve cover, the spring body, and the adjustment seat are integrated through the restraint of the shaft sleeve and the combination sleeve, and a through hole inner wall of the combination sleeve is provided. Protruding ring, which is embedded in a ring groove on the surface of the side end of the bushing to form a limit state, and the other end of the bushing is inserted into the through hole of the copper bushing and protrudes outside the shaft hole of the brake body. A washer is a tight fit.

Through the above structure, it can provide the practical effect that the assembler can quickly and directly install on the vehicle frame.

Detailed ways

First of all, please refer to the detailed description of Fig. 2 and Fig. 3 for cooperation: a bicycle brake caliper of the utility model is combined with a copper sleeve 2, a shaft sleeve 3, and a sleeve at the position of the shaft hole 11 at the bottom of the brake body 1. Cover 4, spring body 5, adjustment seat 6, joint sleeve 7, and then a bolt 8 including a washer 8A is inserted through and screwed into the screw hole 92 of the protruding shaft 91 of the vehicle frame 9 for positioning; wherein, the copper sleeve 2 It is hollow; and a ring groove 31 is provided on the surface of the 3 side ends of the shaft sleeve; The ring circle 61 is used for placing the ring 51 of the spring body 5, and is positioned in the vehicle frame 9 after the combination sleeve 7 is penetrated, and an adjusting bolt 6A is screwed on one side of the seat so that the spring body 5 When the ring 51 of the ring 51 is attached to the surface of the ring 61 of the adjustment seat 6, the adjustment bolt 6A is in contact with the pressure end of the end of the ring 51 of the spring body 5; Cover 4, spring body 5, and adjustment seat 6 are hollow together, and a protruding ring 71 is formed on the inwall of its through hole.

In this way, the sleeve cover 4, the spring body 5, and the adjustment seat 6 are constrained by the shaft sleeve 3 and the coupling sleeve 7 to make them integrated, and a protruding ring 71 provided in the inner wall of the coupling sleeve 7 is embedded in the shaft sleeve 3 The position-limiting state is formed in the ring groove 31 of the brake body 1, and then the other end of the shaft sleeve 3 is inserted into the through hole of the copper sleeve 2 and slightly protrudes outside the shaft hole 11 of the brake body 1 to pass through a washer 8A Make a tight fit and tightly combine (as shown in Figure 3), so that all components can be combined with the brake body 1 before the manufacturer ships to form a whole, so that not only will there be no missing components, And it can be evenly stressed, and then it also provides that the assembler can quickly and directly install it on the vehicle frame 9 as long as the bolt 8 is passed.

It can be seen that the utility model combines the sleeve cover 4, the spring body 5, and the adjustment seat 6 through the shaft sleeve 3 and the coupling sleeve 7, which has a more convenient assembly effect than other traditional structural combinations.
