Abstract
The utility model discloses a wheelchair brake. The wheelchair brake comprises an outer cover (1), two symmetrical annular brake blocks (2) are arranged in the outer cover (1), one ends of the two annular brake blocks (2), opposite to each other, form a rotating connection through a hinge pin (3), and the other ends of the two annular brake blocks (2), opposite to each other, are provided with friction plates (4). An eccentric wheel (5) is arranged between the two friction plates (4), the two annular brake blocks (2) contact the side face of the eccentric wheel (5) through the friction plates (4), the eccentric wheel (5) rotates to drive the two brake blocks to open or close, a snap spring (6) is arranged at the bottoms of the two annular brake blocks, two ends of the snap spring (6) are respectively connected with the two brake blocks (2), and a main part of the snap spring (6) surrounds and contacts the two annular brake blocks (2). The wheelchair brake is capable of effectively increasing brake force and simple in structure.
Description
Technical field
The utility model relates to a kind of break of wheel-chair.
Background technique
The break of present wheel-chair generally adopts band-type brake to brake, and this break not only braking force is little, and the enclasping force when holding tightly is not very large, and more complicated is installed.
Summary of the invention
The utility model provides a kind of break of wheel-chair, and it not only can increase braking force effectively, and simple in structure.
The utility model has adopted following technological scheme: a kind of break of wheel-chair, it comprises outer cover, be provided with two mutual symmetrical annular hoof pieces in the inside of outer cover, the end that two annular hoof pieces are relative forms by bearing pin and is rotationally connected, the relative the other end of two annular hoof pieces is provided with friction plate, between two friction plates, be provided with eccentric wheel, two annular hoof pieces contact with eccentric side by friction plate, eccentric wheel rotates stirs two hoof piece group spreading and closures, bottom in two annular hoof piece groups is provided with jump ring, the two ends of jump ring are connected with two annular hoof pieces respectively, the main body of jump ring along two annular hoof pieces around and contact with two annular hoof pieces.
Described jump ring is set to circular jump ring.
The utlity model has following beneficial effect: be provided with eccentric wheel between the utility model two friction plates, two annular hoof pieces contact with eccentric side by friction plate, eccentric wheel rotates stirs two hoof piece group spreading and closures, bottom in two annular hoof piece groups is provided with jump ring, the two ends of jump ring are connected with two annular hoof pieces respectively, the main body of jump ring along two annular hoof pieces around and contact with two annular hoof pieces, so not only the braking-force ratio band-type brake has improved 20%, greatly increased braking force, and simple in structure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
