[specific embodiment]
See also shown in Figure 1, be bicycle hydraulic disc brake setting device A of the present utility model, its formation of this setting device A comprises the pedestal 10 of a tool room, one fixing protruding seat 20, one piston 30 and a fuel feed pipe 40 are formed, the utility model principal character is: in these pedestal 10 rooms by right and left spiral shell is established into a fixing protruding seat 20, and group is provided with a piston 30 again, should fixing protruding 20 end-rings be provided with screw thread 21, and hexagonal groove 22 in adjustable ring 27 centers of fixing protruding seat 20 ends are provided with, has a nose 23 in fixing protruding seat 20 pedestal front ends and dashing forward, these nose 23 front end appropriate locations also are equipped with groove 231, be provided with catch 24 for group, this piston 30 is to have the nose 23 of groove for ccontaining fixing protruding seat 20, and 23 of piston 30 and noses also are arranged with a diaphragm 25, and be arranged with elastic parts 26 in this diaphragm 25 and 24 of catch; Side chain in addition in pedestal 10 rooms is provided with a permanent seat 50, also spiral shell is provided with one and adjusts piece 51 on this permanent seat 50, and these adjustment piece 51 outside central authorities are provided with hexagonal groove 511 in, around this adjustment piece 51 and be equipped with screw thread 512, again two brake linings 60 are mounted on piston 30 respectively and adjust on the piece 51.
See also shown in Figure 2, it is action scheme drawing for the utility model setting device, when the oil hydraulic cylinder start, make oil that fuel feed pipe 40 squeezes out in oil circuit flows into pedestal 10 rooms, promote diaphragm 25 and then drive piston 30 to advance with brake lining 60, two brake linings 60 clamp disc 70 to reach the effect of brake about making, and then this elastic parts 26 is to be compressive state; It is after oil pressure discharges, and oil refluxes through oil circuit, simultaneously by the restoring force of elastic parts 26, makes quick support flick fixing protruding seat 20 homings, can reach the effect of quick and automatic involution.
Wherein, because two brake linings 60 can wear and tear and attenuation after long-term use with disc 70 about this, cause brake lining 60 gradually big with the spacing of disc 70, the brake reaction time is increased, and then influence the benefit of brake structure, because the fixing protruding seat 20 of the utility model hexagonal groove 22 in tool is provided with respectively with two ends of adjusting piece 51,511, the user can utilize the fixing protruding seat 20 of instrument adjustment or adjust the distance of piece 51, as shown in Figure 3, the brake lining 60 and the spacing of disc 70 are dwindled, increasing the effect of brake structure, and can prolong service life of brake lining 60 and disc 70 again.
Should be connected with an adjustable ring 27 by fixing protruding seat 20 1 ends simultaneously, can temporarily transfer the domain 27 and prevent the excessively adjustment of fixing protruding seat 20, cause the brake function impaired, establish a discharging air pipe 80 in pedestal one side in addition, shown in Fig. 4 A, 4B, install a bleed screw 81, can improve exhausting problem, avoid residual air in oil circuit, cause the bad situation of brake.
By forming with upper member, pushing oil through the oil hydraulic cylinder start makes oil promote piston, and and then promote brake lining to clamp disc, to reach the effect of brake, at this moment, the elastic parts that is sheathed between diaphragm and catch is to be compressive state, after oil pressure discharges, by the restoring force of this elastic parts, make the quick homing of piston, but actv. promotes the brake effect of brake structure, the fixing protruding seat and adjustment piece that cooperate this adjustable position simultaneously, can shorten the spacing of brake lining and disc,, make the real tool Practical Benefit of integral structure to prolong the service life of brake lining and disc.
In sum, bicycle hydraulic disc brake setting device of the present utility model, provide an elastic parts that is sheathed on fixing protruding seat and piston space, when the oil hydraulic cylinder start is pushed oil and promoted piston, and then the start brake lining reaches the brake effect, after oil pressure discharges, and by being sheathed on the elastic parts restoring force of fixing protruding seat with piston space, make the quick involution of piston return original position, while is by the fixing protruding seat and adjustment block assembly of this adjustable position, can dwindle the spacing of brake lining and disc, so that an effect that can improve the brake effect and can increase the service life to be provided, make whole really tool industrial applicability and cost benefit, and its formation structure books and periodicals or public use had not been seen again.
