Abstract

The invention discloses a lifting chair which comprises a chair back and a chair seat. X-type stretchable frames are perpendicularly hinged to the two sides of the lower end face of the chair seat respectively, and the lower ends of the two X-type stretchable frames are hinged to slide grooves in slide rods respectively. At least three pairs of limit clamping grooves are evenly distributed in one side in each slide groove, the chair back is a rectangular frame, a horizontal transverse rod is arranged in the chair back frame, the chair back is hinged to the chair seat, and the chair back and the chair seat are fixed through locking devices. Compared with the prior art, the lifting chair has the advantages that the height of the chair can be adjusted through positions, corresponding to the limit clamping grooves on the slide rods, of the X-type stretchable frames, the height can be adjusted appropriately according to needs, the chair back can be positioned on the lower end face of the chair seat through the locking devices, the transverse rod on the chair back can be used as a step, so that the lifting chair is convenient to climb, and the lifting chair is convenient to use and practical.

Description

A kind of lifting chair

Technical field

The present invention relates to a kind of lifting chair.

Background technology

Existing chair comprise the chair back, seat support and chair leg can not regulate as required the height, if people need to climb, need to be placed on taboret on chair padded, but, connection between taboret and chair is very unstable, easily produces and rocks, and causes danger, and, highly padded after people climb up or get off all inconvenient.

Summary of the invention

The problems referred to above that the present invention need to solve are for above-mentioned the deficiencies in the prior art, and a kind of lifting chair that can regulate height and convenient climbing is provided.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of lifting chair, comprise the chair back and seat support, both sides in the lower surface of seat support vertically are hinged with respectively the X-type expansion bracket, the lower end of described two X-type expansion brackets is hinged on respectively in the chute on slide bar, at least be evenly distributed with three pairs of spacing draw-in grooves on one side in described chute, the described chair back is rectangular framework, is provided with the cross bar of a level in the framework of the chair back, the chair back is hinged on seat support, and fixes by locking device and seat support.

Described locking device is be located at the projection of seat support side and be hinged on the backstay of chair back respective side, and described backstay is provided with at least two grooves with the projection adaptation.

Be provided with connecting rod between described two slide bars.

Described connecting rod has two, and becomes X-type cross.

Compared with prior art, the invention has the beneficial effects as follows: the height of seat support can be regulated the position of corresponding spacing draw-in groove by regulating the X-type expansion bracket on slide bar, can regulate as required applicable height, the chair back can be positioned on the lower surface of seat support by locking device, cross bar on the chair back can be treated as step, be convenient to climbing, convenient and practical.

Fig. 2 is the top view of slide bar.

Wherein, 1, the chair back, 2, seat support, 3, the X-type expansion bracket, 4, slide bar, 5, chute, 6, spacing draw-in groove, 7, connecting rod, 8, cross bar, 9, locking device, 10, projection, 11, backstay, 12, groove.

The specific embodiment

Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of lifting chair, comprise the chair back 1 and seat support 2, the lower end that vertically is hinged with respectively 3, two X-type expansion brackets 3 of X-type expansion bracket in the both sides of the lower surface of seat support 2 is hinged on respectively in the chute 5 on slide bar 4, on the one side in chute 5, at least is evenly distributed with three pairs of spacing draw-in grooves 6, the chair back 1 is rectangular framework, be provided with the cross bar 8 of a level in the framework of the chair back 1, the chair back 1 is hinged on seat support 2, and fixing with seat support 2 by locking device 9.

Locking device 9 is the projection 10 that is located at seat support 2 sides and the backstay 11 that is hinged on the chair back 1 respective side, backstay 11 is provided with at least two grooves 12 with projection 10 adaptations, backstay 11 is provided with a plurality of grooves 12, and the convenient angle of adjusting the chair back 1 and seat support 2, lean against on the chair back 1 more comfortable; Backstay 11 is to be hinged on the side of the chair back 1, can rotate, when the height of lifting chair is heightened, when the chair back 1 can be turned to the lower surface of seat support 2, rotation backstay 11, and groove 12 is stuck on projection 10, fix the chair back 1, be convenient to climbing, safe and practical.

Be provided with connecting rod 7 between two slide bars 4, strengthen steadiness.

Connecting rod 7 has two, and becomes X-type cross more solid and reliable.

Lifting chair of the present invention, the height of seat support 2 can be regulated by the position of regulating X-type expansion bracket 3 corresponding spacing draw-in groove 6 on slide bar 4, can regulate as required applicable height, the chair back 1 can be positioned on the lower surface of seat support 2 by locking device 9, cross bar 8 on the chair back 1 can be treated as step, be convenient to climbing, convenient and practical.
