Abstract
A bicycle contracting brake is composed of a contracting brake box, a contracting brake ring, a contracting brake disc and a pull rope. One end of the contracting brake ring is fixedly connected with the contracting brake box; the pull rope and the other end of the contracting brake ring extend out of the contracting brake box in the tangent direction between the contracting brake ring and the extension line of the pull rope, while the extending part out of the contracting brake box is connected or extended into the contracting brake box and surrounds the contracting brake ring for one circle and then is connected with the contracting brake box. The utility model has the advantages of low cost, simple structure, easy installation and maintenance as well as long service life.
Description
The utility model relates to a kind of bicycle band-type brake.
Existing bicycle band-type brake, stay cord applies application force by tight lock crank throw to the band-type brake circle, its contracting brake box shape more complicated, parts are more, and cost is higher, assembles and adjust also more complicated.
The purpose of this utility model is the deficiency that overcomes existing bicycle band-type brake, and a kind of simple in structure, cost is low, assembling is easy to maintenance bicycle band-type brake is provided.
The bicycle band-type brake comprises contracting brake box, the band-type brake circle, band-type brake dish, stay cord, wherein band-type brake circle one end and contracting brake box are fixed, the band-type brake circle other end passes contracting brake box can the hole from contracting brake box and is connected with stay cord, also can in contracting brake box, dissociate and by stay cord enter in the contracting brake box around one week of band-type brake circle the back be connected with contracting brake box.Under latter event, the outside face of band-type brake circle or the inside face of contracting brake box can be distinguished or be simultaneously fluted, so that the penetrating of stay cord.Stay cord enters contracting brake box or can establish the pulling rope length control apparatus with the position that contracting brake box is fixed.
The utlity model has characteristics such as cost is low, simple in structure, installation and maintenance convenience, long service life.
Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is the constructional drawing of another embodiment of the utility model;
Fig. 3 is that Fig. 2 A-A is to section-drawing.
Below in conjunction with embodiment and accompanying drawing it is described further:
See Fig. 1, band-type brake circle 2 one ends are fixing with contracting brake box 1 by anchor fitting 4, and the other end 7 passes outside the contracting brake box from the hole 8 of contracting brake box 1, link by fastener 5 and stay cord 6.
When stay cord 6 when band-type brake circle 2 applies pulling force, the girth of band-type brake circle 2 in contracting brake box 1 dwindles, contact with band-type brake dish 3 and realize the brake.When stay cord 6 loosens, because the elastic force of band-type brake circle 2 makes itself and band-type brake disk detachment.
In Fig. 2 and Fig. 3, band-type brake circle 2 one ends are fixing with contracting brake box 1 by anchor fitting 4, the other end is free in contracting brake box, stay cord 6 penetrates in the contracting brake box from hole 8, from hole 9, pass outside the contracting brake box after 2 one weeks around the band-type brake circle, realize its fixing with contracting brake box by fastener 10, fastener 10 can be a fastening bolt independently, leans on the pulling force of stay cord to be against on the contracting brake box on the outer wall.Stay cord sleeve pipe 11 is against on the contracting brake box outer wall, and hole 8 diameters are greater than the diameter of stay cord 6, less than the diameter of stay cord sleeve pipe 11, and the 12nd, the pulling rope length control apparatus.The outside face of band-type brake circle and the inside face of contracting brake box fluted 13 and 14 are so that can insert smoothly when assembling and replacing stay cord.
When stay cord 6 applied pulling force, its length in contracting brake box 1 was dwindled, and forced the girth of band-type brake circle 2 to dwindle, contact with band-type brake dish 3 and realize the brake.When stay cord 6 loosens, because the elastic force of band-type brake circle 2 makes itself and band-type brake disk detachment.
Claims (6)
