Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1 to 5, an embodiment of the auxiliary chair of the present invention is proposed:

an auxiliary chair comprises a chair seat 1, a chair back 3, a stabilizing frame 5, a side handle 4 and four supporting legs 2. The back of the chair 3 can be dismantled and connect on 1 rear side of seat support, and side handle 4 can be dismantled and connect on 1 side of seat support, and connection can be dismantled in supporting legs 2 on 1 bottom of seat support.

The seat support 1 includes cushion 11, seat support head rod 12, seat support second connecting rod 13 and seat support third connecting rod 14, and two seat support head rods 12 are crisscross setting in 11 bottoms of cushion, and the both ends of two seat support head rods 12 extend to 1 bottoms of seat support, are provided with first pressure spring 121 on the both ends end of seat support head rod 12. Two seat support second connecting rods 13 are arranged at the bottom of the seat support first connecting rod 12, and a second connecting hole is formed in one side, connected with the chair back 3, of the seat support second connecting rod 13. The seat third connecting rod 14 is arranged on the side surface of the seat first connecting rod 12, and a third connecting hole is formed in the seat third connecting rod 14. The seat cushion 11 is also provided with a plurality of through holes.

2 tops of supporting legs are provided with a plurality of first connecting holes, and through going into first connecting hole with first pressure spring 121 card to with 2 telescopic connection of supporting legs on 1 bottom of seat support, the first connecting hole of co-altitude that accessible adjustment first pressure spring 121 card was gone into, thereby can adjust the height of seat support 1. The stabilizing frame 5 is arranged on the supporting legs 2, and when the height of the auxiliary chair is adjusted, the height of the stabilizing frame 5 from the ground cannot be changed.

The bottom of the chair back 3 is provided with two chair back connecting rods 31, the tail ends of the chair back connecting rods 31 are provided with second pressure springs 32, and the second pressure springs 32 are clamped into the second connecting holes, so that the chair back 3 can be detachably connected to the rear side of the chair seat 1.
