Abstract

The utility model relates to a disk brake structure of bicycles, which mainly comprises a brake main body, a drive arm, an actuating block, a moving block, a bunting and pressing block, a braking block, a clamping block, bead bodies and an elastic body, wherein the actuating block is fixedly connected with the drive arm; the outer margin of the moving block is provided with concave grooves matched with concave grooves of the inner wall of the brake main body, and the moving block is clamped and fixed by the clamping block; the corresponding faces of the actuating block and the moving block are provided with inclined grooves; two corresponding inclined grooves is clamped with the bead bodies; the elastic body is arranged between the other end face of the moving block and one side of a cut ditch of the brake main body. In the utility model, the drive arm is pulled to cause the actuating block to rotate so as to extrude the bead bodies to cause the moving block to transversely move so as to push and bunt the bunting and pressing block so that the braking block can clamp a brake disc. Thus the purpose of brake can be achieved.

Description

The Bicycle dished brake structure

Technical field

The utility model relates to a kind of Bicycle dished brake structure.

Background technology

The Bicycle dished brake structure of prior art as shown in Figure 1, brake push rod 1 comprises a location diskware 101 and one and these location diskware 101 integrated rod members 102, this push rod 1 is installed in brake body 2 inside, and rod member 102 1 outboard end are held up by a crank 3, be installed with spring 6 between crank 3 and the brake body 2, during crank 3 starts, spring 6 compressions are rotated, locate diskware 101 interlocks one brake facing 4 extruding brake discs 5 simultaneously and reach the brake purpose, when removing brake, discharge crank 3, spring 6 rotates replys, and location diskware 101 interlocks one brake facing 4 leaves brake disc 5.There is following defective in this kind structure: during brake, spring 6 must rotate and compress and carry out simultaneously, when removing brake, also must spring 6 rotations discharge elastic force, and crank 3 is restored, and is therefore when emergency brake, locked easily, causes the danger of overturning.

The utility model content

The purpose of this utility model provides a kind of later-model Bicycle dished brake structure, and this structure has effectively overcome the deficiencies in the prior art by the new design concept of utilization, has strengthened the security functions that disc brake uses.

For achieving the above object, the utility model adopts following technical scheme: a kind of Bicycle dished brake structure, mainly comprise the brake main body, actuating arm, make motion block, movable block, press block, slipper, fixture block, pearl body and elastic body, it is characterized in that: the brake body lock is fixed on the vehicle frame, this brake main body appropriate location is provided with one for the ccontaining profile groove of brake disc, slipper is located in the both sides of profile groove, brake main body central authorities are equipped with a containing hole, the stacked successively motion block of doing in the containing hole, the pearl body, movable block, press block and elastic body, making motion block is connected with actuating arm, the movable block outer rim is provided with groove, be complementary with brake main body inner wall groove and engage with a fixture block, the opposite face of making motion block and movable block is equipped with skewed slot, be folded with the pearl body in the two relative skewed slots, movable block is connected with press block, is provided with an elastic body between the inwall of movable block and brake main body profile groove one side, the end face of press block is against the slipper of profile groove one side, and another slipper is fixedly arranged on the opposite side of profile groove.

The described opposite face of making motion block and movable block is equipped with the skewed slot of several five equilibriums, and each is organized and all is folded with the pearl body in the corresponding skewed slot.

The beneficial effects of the utility model are, when having avoided in the prior art emergency brake, because of the locked generation that causes unsafe acts easily.

Fig. 3 is a perspective exploded view of the present utility model;

Fig. 4 is a generalized section of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figures 2 and 3, a kind of Bicycle dished brake structure, mainly comprise brake main body 20, actuating arm 24, make motion block 31, movable block 32, press block 34, slipper 39, fixture block 322, pearl body 33 and elastic body 36, it is characterized in that: brake main body 20 is locked on the vehicle frame 10, these brake main body 20 appropriate locations are provided with one for the ccontaining profile groove 23 of brake disc 50, slipper 39 is located in the both sides of profile groove 23, brake main body 20 central authorities are equipped with a containing hole 22, the stacked successively motion block 31 of doing in the containing hole 22, pearl body 33, movable block 32, press block 34 and elastic body 36, making motion block 31 is connected with actuating arm 24, movable block 32 outer rims are provided with groove 320, be complementary with brake main body 20 inboard wall grooves and engage with a fixture block 322, the opposite face of making motion block 31 and movable block 32 is equipped with skewed slot 321, be folded with pearl body 33 in the two relative skewed slots 321, movable block 32 is connected with press block 34, be provided with an elastic body 36 between the inwall of movable block 32 and brake main body profile groove 23 1 sides, the end face of press block 34 is against the slipper 39 of profile groove 23 1 sides, and another slipper 39 is fixedly arranged on the opposite side of profile groove 23.

The described opposite face of making motion block 31 and movable block 32 is equipped with the skewed slot 321 of several five equilibriums, and each is organized in the corresponding skewed slot 321 and all is folded with pearl body 33.

As shown in Figure 4, during brake, hold up actuating arm 24, making motion block 31 rotates simultaneously, because oblique movable block 32 can't rotate by fixture block 322 controls and groove 321 from the superficial to the deep is provided with, doing motion block 31 rotations makes pearl body 33 be rolled into shallow place by the depths in skewed slot 321, movable block 32 is subjected to 33 extruding of pearl body to hold capable moving level with both hands to profile groove 23, make press block 34 pushing and pressing slipper 39 clamp brake disc 50, at this moment, the elastic body 36 that is provided with between the inwall of movable block 32 and brake main body profile groove 23 1 sides is held row because of movable block 32 level with both hands to profile groove 23 and is moved the elastic force increasing; When removing brake, only need to discharge actuating arm 24, at this moment, elastic body 36 discharges elastic force, movable block 32 is moved to hold row level with both hands away from profile groove 23, thereby make slipper 39 leave brake disc 50, simultaneously, pearl body 33 causes and does motion block 31 rotations because of pressure release goes back to the depths by shallow place, makes the position before actuating arm 24 returns back to brake.
