Abstract
The utility model discloses a brake disk which is characterized by comprising the components of: a cover body which is provided with a through hole at the central position of the cover body; and a holding member which is movably connected with the through hole and is provided with a projected part that projects to the cover body and a planar part that extends on the external surface of the cover body. The planar part of the holding member is movably connected with a rocker through a bolt or screw. The cover body is internally provided with two arc-shaped movable blocks symmetrically. One end of each of the two arc-shaped movable blocks, which opposes each other, is connected with the bolt or the screw through a friction sheet. The other opposite end is movably connected through a pin. The brake disk provided by the utility model can be inserted into a wheel hub of a wheel chair for performing outer expansion type braking. Furthermore the brake disk can be firmly fitted with the wheel hub. Quick and powerful braking is realized.
Description
Technical field
This utility model relates to a kind of brake disc, relates in particular to a kind of brake disc for wheel-chair.
Background technology
The at present brake of the brake disc on wheel-chair effect is not fine, and uses and be not easily, and complex structure, is difficult to processing, and dismounting inconvenience, and this can cause very large puzzlement to handicapped people, and manufacturing cost is high.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, handling ease, the convenient and safe and reliable wheel-chair brake disc of dismounting.
The technical solution adopted in the utility model is as follows:
A kind of brake disc, comprises lid, is provided with through hole at the center position of described lid; Gripping member, is movably connected on described through hole, and described gripping member has the ledge stretching out to described lid, and the planar section extending at described cover outer surface; On the planar section of described gripping member by bolt or the screw rocking bar that has been movably connected; Be symmetrically arranged with two arc movable blocks in the inside of described lid, one end that described two arc movable blocks are relative is connected to described bolt or screw place by friction plate, and the relative other end is by the bearing pin connection of moving.
Preferably, the ledge of described gripping member comprises vertical component and horizontal component, on described vertical component, is formed with circular hole, on described horizontal component, is formed with elongated hole.
Preferably, the end of described rocking bar is provided with circular hole.
Brake disc of the present utility model, the wheel hub that can embed wheel-chair carries out outer expanding brake, and can coordinate with wheel hub firmly, and skidding is strong rapidly.
Accompanying drawing explanation
Fig. 1 is the front view of brake disc of the present utility model.
Fig. 2 is the top view of brake disc of the present utility model.
The specific embodiment
With reference to the accompanying drawings this utility model is described more fully, exemplary embodiment of the present utility model is wherein described.
Fig. 1 is the front view of brake disc of the present utility model.Fig. 2 is the top view of brake disc of the present utility model.
As illustrated in fig. 1 and 2, brake disc of the present utility model, comprises lid 2, is provided with through hole at the center position of described lid 2; Gripping member 3, is movably connected on described through hole, and described gripping member 3 has the ledge 31 stretching out to described lid, and the planar section 32 extending at described cover outer surface; On the planar section 32 of 3 of described grippings by bolt or screw 4 rocking bar 1 that has been movably connected; Be symmetrically arranged with two arc movable blocks 5 in the inside of described lid 2, one end that described two arc movable blocks 5 are relative is connected to described bolt or screw place by friction plate 7, and the relative other end connects by bearing pin 6 motions.
Preferably, the ledge 31 of described gripping member comprises vertical component and horizontal component, on described vertical component, is formed with circular hole, on described horizontal component, is formed with elongated hole.This elongated hole is fixed on brake disc above wheelchair, so that brake disc can be braked to wheelchair by extruding, thereby makes brake operation simple and convenient.
Preferably, the end of described rocking bar 1 is provided with circular hole.This circular hole connects brake cable, in the time that needs brake, only need pull rocking bar 1 gently, just can make two arc movable blocks 5 to both sides extruding, and then plays the effect of brake.
In actual use, brake disc of the present utility model is arranged on the appropriate location of wheel hub, in the time that needs brake, only need one hand to hold gripping member 3 and rocking bar 1, then by gripping member 3 and rocking bar 1 each other by doing, just can stop the action of wheel-chair, simple to operate, good braking effect, and brake disc is simple in structure, handling ease is applicable to batch production very much.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
