Bicycle brake structure

This creation is about a brake device, especially a C-clip bicycle brake structure.

According to the conventional bicycle brake device structure, please refer to the figures 7 to 10, which includes: a first clamping arm 40, a second clamping arm 50, and a pair of first and second The connecting block 60 of the clamping arm 40, 50, wherein the first clamping arm 40 has a braking block mounting portion 41 and a cable mounting portion 42. The braking block mounting portion 41 has a connecting through slot 43 above the connecting portion. The slot 43 is provided with a shaft bolt 44. The second clamp arm 50 has a brake block mounting portion 51 and a cable laying portion 52, and is further connected to the side by the brake block mounting portion 51 and the cable laying portion 52. A combination portion 53 is extended and is coupled to the first clamping arm 40 by the combining portion 53 so that the cable insertion portion 52 is located on the same side as the cable mounting portion 42 of the first clamping arm 40, and is further composed of the combining portion 53. A pivoting slot 54 is provided. The pivoting slot 54 is provided with a bolt 55. The connecting block 60 is connected to the slot 43 and the pivoting slot 54 is provided with a connecting slot 61 and a locking hole 62. The connecting slot 61 is sleeved on the shaft bolt 44 and provides a locking member 63 to be locked and locked with the shaft bolt 44. The locking hole 62 is screwed and fixed by the bolt 55. Further, a nut 64 is provided to be locked and positioned with the bolt 55 outside the connecting block 60, and an elastic member 65 is further connected between the connecting block 60 and the second clamping arm 50, thereby completing a bicycle brake structure and pulling through the steel cable.掣The first and second clamp arms 40, 50 are controlled, and the two brake block mounting portions 41, 51 can be clamped in the direction of the rim to achieve the braking effect.

It is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reasons are as follows: According to the conventional first and second clamp arms 40 and 50 and the connecting block 60, the shaft bolt 44 and the bolt 55 are transmitted. The bolting connection, when the first and second clamp arms 40, 50 are actuated by the steel cable pulling, the yaw is biased by the shaft bolt 44 and the bolt 55 as a fulcrum, but the shaft bolt 44 and the bolt 55 are combined with the first and second clamps. The connecting slots 43 and the pivoting slots 54 of the arms 40, 50 form a large area of frictional contact, and can provide limited lubrication effect, greatly increasing the yaw resistance of the first and second clamping arms 40, 50, so that the brakes are pulled When the handle is pressed, it is necessary to apply a large force to achieve the braking effect. On the other hand, when the handle is loosened, the frictional resistance is large and cannot be effectively rebounded through the elastic member 65, and the elastic coefficient must be changed. The elastic member 65 leads to an increase in cost and a lack of economic efficiency.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide a bicycle brake structure for the above-mentioned shortcomings existing in the prior art.

The utility model relates to a bicycle brake device, which comprises: a first and a second clamping arm which are opposite to each other, and a pair of connecting blocks which are opposite to the first and second clamping arms, wherein the first clamping arm is provided with a connecting through slot for providing a through hole The second clamping arm is provided with a pivoting slot for providing a bolt, and the connecting slot and the pivoting slot are embedded with at least one bearing member, and the connecting block is correspondingly connected The slot and the pivoting slot are provided with a connecting slot and a locking hole, and the connecting slot is provided with at least one bearing component and is sleeved on the axle bolt, and provides a locking component and a bolt locking positioning. The locking hole is fixed by the bolt screw, and a nut and a bolt are locked and positioned outside the connecting block, as described above, To form a bicycle brake device structure.

According to the effect of the prior art: (1), because the connecting groove of the first clamping arm and the pivoting groove of the second clamping arm are provided with bearing parts, when the first and second clamping arms are respectively used as shaft bolts and bolts When the fulcrum is biased, the cymbal can achieve a low-friction yaw state through the bearing member, so as to prevent the swaying pulling force from being weakened by friction, so that the user can more easily and effortlessly press the stalk of the brake, and the brake is surely and smoothly. effect.

(2) On the other hand, when the brake handle is loosened, the rebound stress can be effectively prevented due to the friction coefficient being reduced, so that the low-pound elastic member can truly achieve the rebound reset of the first and second clamp arms, Reduce the cost of selection of elastic parts, and be economical.
