Section, the side of hold-down segment constitutes brake end face.
Torsion spring is arranged with 3rd rotating shaft.
Using the Brake of wheel-chair of the structure, handle is lifted upwards first during releasing of brake, now handle upwards lifting and
Take advantage of a situation and first connecting rod is lifted upwards, first connecting rod also to be taken advantage of a situation and lift upwards second connecting rod, final second connecting rod is by brake lever
Lifting upwards, while the upward resilience of torsion spring in the 3rd rotating shaft, brake lever is flicked toward the direction beyond tire wall, it is to avoid go out
Existing stuck phenomenon.
The first rotating shaft is arranged on the top of the 3rd rotating shaft.
The beneficial effects of the utility model are：
（1）The utility model is a kind of brake structure of wheelchair, first when being braked using the Brake of wheel-chair of the structure
First handle is detained, now handle push down on first connecting rod to lower swing and taking advantage of a situation, first connecting rod is also taken advantage of a situation and connect second
Bar is pushed down on, and final second connecting rod pushes down on brake lever, brake lever is mutually compressed with tire wall, reaches the mesh of brake
's；
（2）The utility model is a kind of brake structure of wheelchair, is first lifted handle upwards during releasing of brake, now hand
Handle is lifted and taken advantage of a situation and lift upwards first connecting rod upwards, and first connecting rod also to be taken advantage of a situation and lift upwards second connecting rod, and final second
Connecting rod lifts brake lever upwards, brake lever is maked somebody a mere figurehead with tire wall, reaches the purpose of releasing of brake；
（3）The utility model is a kind of brake structure of wheelchair, and simple compact, the easy to use, operation of the brake structure is saved
Power and braking effect is good.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model is in releasing of brake state.
Fig. 2 is the structural representation that the utility model is in braking state.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Fig. 1 to 2, a kind of brake structure of wheelchair, including fixed seat 1, link assembly 2, handle 3 and brake lever
