Abstract
The invention discloses a caliper brake for a bicycle. The caliper brake comprises a left brake fork, a right brake fork, a penetrating shaft and a return spring. An interlocked limiting rivet is arranged in the middle of the right brake fork, a flat interlocked limiting hole is formed at the end part of the interlocked end of the left brake fork, the interlocked limiting rivet is assembled in the interlocked limiting hole and can slide in the interlocked limiting hole; one end of the penetrating shaft is fixed in the middle of a fixing plate, and the two ends of the fixing plate are hinged with the bends of the left brake fork and the right brake fork respectively; the middle part of the return spring is fixed in the connection position of the penetrating shaft and the fixing plate, and the two fins of the return spring are arranged inside a left return spring rivet and a right return spring rivet on the left brake fork and the right brake fork respectively. The caliper brake can ensure simultaneous interlocking of the left brake fork and the right brake fork, so that the left brake shoe and the right brake shoe can apply the brake to the bicycle wheel hubs simultaneously with identical force, thereby enhancing the braking effect. The caliper brake can also ensure simultaneous return of the left brake fork and the right brake fork, and overcome the phenomenon that one brake fork returns but the other brake fork can not return, and the brake shoes are still attached on the wheel hubs in the prior art.
Description
Technical field
The present invention relates to a kind of caliper brake for bicycle, belong to the bicycle brake technical field.
Background technology
Existing caliper brake for bicycle is made of left lock fork, right brake fork and retracing spring, and as shown in Figure 1, 2, left lock fork and right brake fork are hinged on the left and right sides of anchor shaft, are resetted by retracing spring control.When brake, brake cable pulling right brake fork rotates counterclockwise around anchor shaft, and right brake pad is adjacent to rim, continues the pulling brake cable, and left lock fork clockwise rotates thereupon, and left brake pad is adjacent to rim, thus car brakeing.When the releasing of brake line, retracing spring should reset the left and light brake fork of both sides.But, at this moment often have only right brake fork to rotate and reset, and left lock fork to be motionless, left brake pad still is attached on the rim.This is the major defect of this brake, and for a long time, those skilled in the art thirsts for solving and fails to solve.
Summary of the invention
Technical matters to be solved by this invention just is to overcome the defective that prior art exists, and a kind of caliper brake for bicycle with new structure is provided, and can guarantee no matter the left and light brake fork is brake or resets and can both move simultaneously.
Caliper brake for bicycle of the present invention, comprise left lock fork, right brake fork, punching axle and retracing spring, it is characterized in that: the middle part of right brake fork is provided with the spacing rivet of interlock, the interlock end end of left side lock fork is provided with flat interlock spacing hole, the spacing rivet of described interlock is assemblied in the described interlock spacing hole, can slide in interlock spacing hole; One end of punching axle is fixed on adapter plate middle part, and the two ends of adapter plate are hinged with the turn of bilge of left lock fork and right brake fork respectively; The connecting portion of punching axle and adapter plate is fixed at the middle part of retracing spring, other respectively left retracing spring rivet, the right retracing spring rivet inboard on left lock fork and right brake fork bottom of two wings of retracing spring.
The outside is set with nylon spacer in the hinge-point of described adapter plate at both ends.
The spacing rivet of described interlock is the suit nylon spacer between left lock fork and right brake fork.
Described adapter plate is a falcate.
The brake rubber block assembly of left side lock fork and right brake fork is installed end plate and is provided with elongated hole, and the screw rod of brake rubber block assembly is threaded onto in the elongated hole, and is fastening with cover type nut.
The inboard that described brake rubber block assembly is installed end plate is a male and female face.
Two wings of described retracing spring are respectively at the anti-sliding sleeve of the position suit that contacts with left retracing spring rivet, right retracing spring rivet.
Caliper brake for bicycle of the present invention can guarantee no matter the left and light brake fork is brake or resets and can both link simultaneously that the brake rubber block that makes left and light brake stick waits power to brake to vehicle hub simultaneously, has strengthened the drag effect.In addition, behind the take-off the brake, the left and light brake fork resets simultaneously, overcome the monolithic lock fork that often produces in the prior art and resetted, and another lock fork can not reset, and its brake rubber block still is attached to the phenomenon on the wheel hub.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Shown in Fig. 3,4,5,6, caliper brake for bicycle 1 of the present invention comprises left lock fork 2, right brake fork 10, punching axle 31, retracing spring 27, adapter plate 20 and brake rubber block assembly 45.The middle part of right brake fork 10 is provided with interlock spacing rivet 14 (seeing Figure 10, Figure 11), the interlock end end of left side lock fork 2 is provided with flat interlock spacing hole 7 (seeing Fig. 7, Fig. 8), the spacing rivet 14 that links is threaded onto in the interlock spacing hole 7, can in interlock spacing hole, slide, by spacing rivet 14 and the interlock spacing hole 7 of linking, can limit the movement position of left and right lock fork, make left and right lock fork and brake rubber block assembly thereof brake simultaneously and reset simultaneously; The spacing rivet 14 suit nylon spacer 25 between left lock fork and right brake fork that links is used to isolate left and right lock fork, phase mutual friction when avoiding braking; One end of punching axle 31 is fixed in the center hole 23 at adapter plate 20 middle parts.The right-hand thread rivet 16 of right brake fork 10 turn of bilges is installed in the right-hand thread rivet connecting bore 24 of adapter plate 20, and it is fastening with jam nut 35, form hinge and connect (hinged), the outside is set with nylon spacer (42,43) in the adapter plate of hinge-point, to avoid phase mutual friction between metal piece, 41 is metal washer among the figure.The left-hand thread rivet 5 that left side lock is pitched 2 turn of bilges is installed in the left-hand thread rivet connecting bore 22 of adapter plate 20, also uses jam nut 35 fastening, forms hingedly, is set with nylon spacer (42,43) outside in the adapter plate of hinge-point, to avoid phase mutual friction between metal piece.Punching axle 31 is being equipped with punching hub 28 with adapter plate bonded assembly one end, jam nut 29 is established in punching hub outer end, install retracing spring 27 (middle part of retracing spring is positioned at the punching hub) in the punching hub 28, other respectively left retracing spring rivet 4, right retracing spring rivet 17 inboards on left lock fork and right brake fork bottom of two wings of retracing spring.Two wings of retracing spring are respectively at the anti-sliding sleeve 44 of the position suit that contacts with left retracing spring rivet, right retracing spring rivet.
