Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1 and 2 together, fig. 1 is a side view of a lying wheelchair according to an embodiment of the present application; fig. 2 is a rear view of a lying wheelchair according to an embodiment of the present application. As shown, a lie flat wheelchair includes side brackets 10 on both sides; a seat 20 which is connected with the side supporting frame 10 in a buckling way; reinforcement arms 30 cross-connecting side brackets 10; a pivot handle 40 welded to the side frame 10 and located at the rear side of the seat 20; a chair back 60 pivoted to the pivot handle 40 and locked by the back-rest adjusting assembly 50; a side guard frame 70 mounted on at least one side of the side support frame 10; and a leg rest 80 which is arranged at the front end of the side supporting frame 10 and can be turned over.

In one embodiment of the present invention, the side brackets 10 are separated on both sides to realize lower support and to fasten and fix the seat 20 at the upper end. Meanwhile, in order to strengthen stability, the cross reinforcing arms 30 are used for connecting and fixing the side supporting frames 10, and the device is practical and convenient. The chair seat 20 is installed at the upper end of the side supporting frame 10 in a buckling mode, the hinge handle 40 with equal height is welded at the rear side of the chair seat 20, the chair back 60 is pivoted at the upper end of the hinge handle 40, the rear side of the chair back 60 is supported by the backrest adjusting component 50, the angle can be freely adjusted, the sitting and lying functions are achieved, and the practicability is improved. In addition, the front end of the side supporting frame 10 is also provided with a reversible leg rest 80 which can be conveniently lifted and abutted against the leg, thereby improving the comfort.

The side frame 10 includes an upper beam portion 11 supporting the seat 20; a front vertical pipe beam part 12 and a rear vertical pipe beam part 13 respectively bent at two ends of the upper pipe beam part 11; and a lower tube beam portion 14 connecting the front tube beam portion 12 and the rear tube beam portion 13 by a boss. From this one, the frame-shaped encloses and establishes, and stability is strong, and the bushing connection is convenient for install and dismantle simultaneously, accomodates the convenience.
