Description

A bicycle plug-in brake handle structure

Technical field

The utility model relates to a bicycle plug-in brake handle structure, in particular to a plug-in fixed brake that is arranged at the end of the bicycle driver's pipe or fixed at the end of the pipe such as the auxiliary grip pipe of the driver's pipe. Handle structure.

Background technique

Please refer to Fig. 1, the conventional plug-in type brake handle 1 is to set the frame tube end 21 of the bicycle rider tube 2, and it utilizes the slightly "匚" shaped brake handle 1, so that the joint section 11 is fixed by a locking screw 12 to fix the brake handle 1 to the pipe end 21 of the driver tube 2, and then because the driver tube 2 is preset with a wire inlet 22 and a wire outlet 23, it is only used for the brake wire 3 to pass through, so that when the puller is pressed When the section 13 of the brake handle 1 is pressed, the brake cable 31 wrapped in the brake cable 3 is pulled, so that the brake calipers at the other end of the brake cable 31 clamp the wheel to achieve the purpose of braking the wheel; Wherein, by the arrangement of the above-mentioned traditional plug-in brake handle 1, in practice, it is found that all ends are missing and need to be improved, such as:

1. From a mechanical point of view:

Traditionally, the pipe end of the bicycle rider's pipe body is preset with a wire inlet 22 and a wire outlet 23, so as to facilitate the insertion and passage of the brake line 3; The protruding sections are often covered with glue or leather rings to achieve an aesthetic effect. In fact, the design of the protruding section 32 of the brake line 3 has considerable flaws, because the brake line 3 must be placed inside the outlet 23 of the driver's pipe 2. It extends out of the pipe body through secondary bending. Therefore, the brake cable 31 in the brake line 3 has already caused an offset component force on the pull action, resulting in an increase in the frictional resistance of the brake cable in the brake line. And the active force of pulling and pressing the brake also increases thereupon, which does not conform to the principle of labor saving in mechanics and benefit.

Second, in terms of visual aesthetics:

The exposed design of the protruding section 32 of the brake line 3 extending from the outlet 23 of the driver's pipe body has actually hindered the appearance of the bicycle, and there are many reasons to prevent the braking function from being accidentally touched or hooked. It is a covering ring belt, but the formed handle frame tube body after covering is a non-circular irregular shape, and there is no aesthetic feeling at all.

Third, in terms of assembly benefits:

Its brake line 3 shells are very easy to be penetrated by the line inlet of the driver's pipe body, but because the line outlet 23 is to establish side holes in the pipe wall of the pipe body, therefore, the brake line inside the pipe body must be turned in the right direction when assembling. It can be worn out, so it is quite inconvenient to assemble.

Contents of the invention

The main purpose of the utility model is to provide a bicycle plug-in brake handle structure with simple structure, easy installation and good braking effect.

In order to achieve the above purpose, the utility model adopts the following structure: a bicycle plug-in brake handle structure, the brake handle is fixed at the end of the bicycle driver's pipe, or the end of other auxiliary grip pipes connected to the driver's pipe , wherein the brake handle is slightly "匚"-shaped, and a locking screw is used to sequentially pass through the stop ring, spring and locking seat in its joint section, and the brake handle is fixed on the end of the handle frame, and the driver The tube is preset with a line inlet for the brake wire to pass through, wherein one end of the brake cable is embedded in the proximal end of the brake handle pressing section, and the brake cable is passed through the shaft set by the locking screw inside the joint section. to the through hole, and the other end is located in the brake line casing stuck against the abutment groove; one end of the locking seat is provided with a ring taper socket and an abutment groove.

The arrangement of the above structure can be used to guide and resist the positioning of the brake cable casing from the cable inlet, and facilitate the threading of the brake cable, so that the brake cable does not need to be twisted and stretched out after being inserted into the cable inlet of the handle frame The outside of the pipe body, and when the pressing section of the brake handle is pulled, the brake cable wrapped in the brake cable can directly and effectively affect the brake caliper at the other end of the brake cable to clamp the wheel and brake without turning. Stop the wheel.

Detailed ways

Please refer to the drawings, a bicycle plug-in type brake handle structure, the brake handle 4 is fixed on the pipe end 51 of the bicycle rider's tube 5, or the tube end of other auxiliary grip tubes connected to the rider's tube 5, Wherein the brake handle 4 is slightly "匚" shape, and the joint section 41 uses a locking screw 42 to pass through the stop ring 43, the spring 44 and the locking seat 45 in order, and the brake handle 4 is fixed on the driver tube 5 The pipe end 51 of the driver pipe 5 is preset with a line inlet 52 for the brake wire 6 to penetrate, wherein one end of the brake cable 61 is embedded in the near end of the brake handle 4 pressing section 46, and the brake cable 61 Through the axial through hole 421 set by the locking screw 42 inside the joint section 41, it enters the brake line casing 62 that is stuck in the resisting groove 452; one end of the locking seat 45 is provided with a ring taper socket 451 and The stop groove 452 can be used to guide and resist the positioning of the brake line casing 62 from the line inlet 52, and is conducive to the penetration of the brake cable 61, so that the brake line 6 can enter the line entrance 52 of the driver's pipe 5. After that, there is no need to turn and stretch out the outside of the pipe body, and when the pressing section 13 of the brake handle 1 is pressed, the brake cable 61 wrapped in the brake line 6 can directly and effectively affect the brake cable 61 at the other end. The brake caliper brakes the wheel by clamping the wheel.

Wherein, the locking screw 42 in the brake handle 4 is screwed into the locking seat 45, and the locking seat 45 can be drawn closer to the stop ring 43 during the screw locking process. At this time, the ring of the locking seat 45 The sheet 453 is stretched out, so as to abut against the inner side of the frame tube end 51 of the driver's tube 5 to position the brake handle 4 . Without affecting the fixing function of the locking screw 42, the utility model is provided with an axial through hole 421 near the center, for the brake cable 61 to pass through and to be actuated by telescopic displacement.

When assembling, first fix the brake handle 4 with the locking screw 42, then insert one end of the brake cable 61 into the proximal end of the pressing section 46, and insert the other end into the shaft of the locking screw 42 in sequence. After reaching the through hole 421 and the brake wire 6 casing 62 stuck in the abutment groove 452, it is extended and connected to the brake caliper, wherein the brake wire 6 casing 62 is preset by the handle frame 5 through the wire inlet 52 The brake cable 61 is inserted into and abutted against the abutting groove 452 through the guide of the ring taper socket 451 of the locking seat 45 , so that the brake cable 61 can easily pass through.
