Detailed description of the invention

In order to make those skilled in the art be more fully understood that the technical solution of the utility model; below in conjunction with accompanying drawing of the present utility model; the technical solution of the utility model is carried out clear, complete description; based on the embodiment in the application; other similar embodiment that those of ordinary skill in the art obtain under the premise not making creative work, all should belong to the scope of the application protection.

Embodiment one:

As shown in Figure 1, Figure 2 and Figure 3, a kind of chair, including pedestal 1, bracing frame and the chair back 3, described pedestal 1 is flexibly connected with bracing frame, the described chair back 3 removably connects with bracing frame, and support frame as described above includes supporting leg 2 and position-limit mechanism, and described supporting leg 2 is flexibly connected with pedestal 1. Described position-limit mechanism includes cross bar 5 and connecting rod 6, described cross bar 5 is between two supporting legs 2, described connecting rod 6 one ends wound is on described cross bar 5, the other end forms outside bending leg and is flexibly connected with pedestal 1, described connecting rod 6 is V-structure, described pedestal 1 is welded under contiguous block 7, and described contiguous block 7 is provided with hole clipping 8, and described bending leg coordinates with described hole clipping 8. Collapsible, detachable chair of the present utility model, when installing and using, one end of this V-type connecting rod 6 is wound around on described cross bar 5, it is possible to slide on described cross bar 5; Two bending legs of other end V-type port are buckled in the hole clipping 8 that contiguous block 7 is provided with, and this chair does not have loaded down with trivial details parts, thus realizing installing flexibly, it is simple to dismounting, save the unnecessary time.

As shown in Figure 4, chair of the present utility model, the described chair back 3 is provided with chair bar 4, described chair bar lower end 41 extends to one end 21 grafting above pedestal 1 with supporting leg 2, described chair bar lower end 41 is hollow-core construction, described supporting leg 2 upper end 21 is provided with inserting section 11, the external diameter of described inserting section 11 is less than the internal diameter of chair bar 4, supporting leg 2 is except inserting section 11, the external diameter of remainder is identical with the external diameter of chair bar 4, so both grafting can be positioned, after can also making grafting, chair bar 4 and supporting leg 2 are integrally forming, do not stay projection, scratch when preventing from using, in addition, the length of described inserting section 11 is at least 15cm, collapsible except realizing, outside detachable function, strengthen the fastness of Chair structure further.

As shown in Figure 5, described pedestal 1 is welded under hollow crossbeam 9, described supporting leg 2 is provided with loop bar 10, described crossbeam 9 is sleeved on outside described loop bar 10, so that whole bracing frame can rotate around pedestal 1 is folding, during chair dismounting, support frame as described above and pedestal 1 fold flat, in the wild during outing, be positioned in dolly boot, do not take up space, described Chair structure stability is high, can bear the weight of 2-3 adult, additionally, chair of the present utility model is provided with the chair back 3, facilitates old man and child use out of doors.
