Description
Technical field
This utility model relates to a kind of wheelchair, relates in particular to a kind of fluid pressure type retractor device of wheelchair bracing frame.
Background technology
At present, the retractor device structure on traditional wheelchair is complicated, and manufacture difficulty is large, and maintenance difficulty also is not easy; Operate also more loaded down with trivial detailsly, the precision of adjusting is also not high enough.
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of fluid pressure type retractor device.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of fluid pressure type retractor device comprises body and plug, and the plug overcoat has a female pipe, and female pipe and a plug part are installed in body interior, are provided with a brake component in the plug lower end, and brake component links to each other with spring.
The intracavity section of described body is shaped as rectangle.
Described female tube cavity cross sectional shape is rectangle.
The beneficial effects of the utility model: this utility model is simple in structure, and is easy to operate; Adopt fluid pressure type easily can realize automatization and overload protection; The life-span of using is longer.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of fluid pressure type retractor device, comprise body 1 and plug 5, plug 5 overcoats have a female pipe 4, female pipe 4 and plug 5 parts are installed in body 1 inside, are provided with a brake component 3 in plug 5 lower ends, and brake component 3 links to each other with spring 2, the intracavity section of described body 1 is shaped as rectangle, and described female pipe 4 intracavity sections are shaped as rectangle.During use, press plug 5 after, plug 5 moves downward, and brake component 3 is unclamped, female like this pipe 4 just can up-down adjustment.The beneficial effects of the utility model: this utility model is simple in structure, and is easy to operate; Adopt fluid pressure type easily can realize automatization and overload protection; The life-span of using is longer.
