Abstract
The utility model provides an expansion brake of a wheelchair, which relates to the field of brakes, and comprises a switch box assembly, a brake-shoe pad assembly and an eccentric gear. The switch box assembly and the brake-shoe pad assembly are combined by welding. The eccentric gear and a butterfly gasket are inserted into the switch box assembly, and are fixedly connected to each other through a cap nut. The upper end of the switch box assembly is provided with a crank throw, and the upper end of the crank throw is provided with a rope-tightening screw hole. The brake-shoe pad assembly is provided with a left shoe pad and a right shoe pad, which are fixed to a fixed core. The fixed core is disposed at the lower end of the switch box assembly through the butterfly-shaped gasket and the cap nut. The expansion brake of a wheelchair is simple in structure, high in stopping and brake performance, and good in safety.
Description
Technical field
The utility model relates to brake field, relates in particular to a kind of wheel-chair that line uses lock that rises of stopping of affecting on the wheel-chair wheel hub that is installed in.
Background technique
The break of existing ordinary wheel Wheel-chair is that wheel rim brake type manufacturing structure is complicated, uses mainly as parking function, and braking function is poor, now designs a kind of wheel-chair car lock that rises, and simple in structure, Parking and braking ability are better.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that former wheel-chair brake exists, and provides a kind of simple in structure, the new wheel-chair that Parking and braking ability are high, Security the is good lock that rises.
The technological scheme that the utility model adopts is: a kind of wheel-chair lock that rises, it comprises fuse-box sub-component, brake shoe assembly and eccentric wheel, described fuse-box sub-component and brake shoe assembly adopt the welding combination, described eccentric wheel and butterfly gasket insert the fuse-box sub-component and are connected and fixed by acorn nut, described fuse-box sub-component upper end is equipped with crank throw, and the tight rope screw hole is equipped with in the crank throw upper end.
Described brake shoe assembly is provided with left hoof piece and right hoof piece, and described left hoof piece and right hoof piece are fixed on to be decided on the core.
Describedly decide core and be installed in fuse-box sub-component lower end by butterfly gasket and acorn nut.
The utlity model has following beneficial effect: the utility model not only adopts the box-like structural design of soldering group, and the braking braking ability is good, little steering force, and use novel environment friendly ceramic fiber friction material, braking is as good as sound.
Description of drawings
Fig. 1 is the utility model schematic representation.
