Description

A kind of folding dining chair

Technical field

The utility model relates to a kind of chair, particularly a kind of folding dining chair.

Background technology

The outdoor chair that the family expenses dining chair of commonly using at present or garden are used adopts reassembling type or one Welding Structure to be made usually, the chair of reassembling type need to carry out loaded down with trivial details assembling when using, power when relatively expending, particularly when collection, have and to dismantle the smaller volume that just can make chair, and the dismounting back part is more scattered, also is not easy to preserve; Although the welded chair of one does not need dismounting before use, the monomer volume ratio of chair is larger, need to take larger space during collection.For this point shortcoming, be necessary to make improvements.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of folding dining chair that does not need dismounting.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of folding dining chair mainly comprises wide batten, fillet plate, rear foot tube, adapter, seat pipe, bolt, gangbar, stull pipe, front foot pipe, seat stay pipe; It is characterized in that two rear foot tubes that be arranged in parallel are fixed together by stull pipe and seat stay pipe, have formed the quadrilateral frame of rigidity; The wide batten of polylith and fillet plate are installed on rear foot tube; Hinged two adapters that be arranged in parallel on rear foot tube, an end of two seat pipes that be arranged in parallel is installed on adapter, and the other end is fixed together by the seat stay pipe; Upper hinged two adapters that be arranged in parallel of seat pipe, the wide batten of polylith and fillet plate set firmly on present pipe; One end of two front foot pipe that be arranged in parallel is installed on adapter, and the other end is fixed together by the stull pipe; One end of two gangbar that be arranged in parallel is hinged on rear foot tube, and the other end is hinged on front foot pipe.

Described adapter can be respectively around rear foot tube and seat pipe directional rotating.

Described gangbar can be rotated around rear foot tube and front foot pipe respectively.

Formed quadric chain between described rear foot tube, seat pipe, front foot pipe, gangbar.

the utility model has the advantages that: set firmly the wide batten of polylith and fillet plate on rear foot tube as backrest, set firmly the wide batten of polylith and fillet plate on the seat pipe as seat surface, rear foot tube is hinged by adapter and seat pipe, the seat pipe is hinged by adapter and front foot pipe, front foot pipe and gangbar are hinged, gangbar and rear foot tube are hinged, the crus curvilineum pipe, the seat pipe, front foot pipe, the quadric chain that forms between gangbar is controlled expansion and the folding of chair, therefore the utlity model has simple in structure, easy to operate, be fit to the sandy beach, camp, the characteristics such as the various occasion uses such as garden.

The specific embodiment

Below by specific embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described further.

Embodiment: with reference to Fig. 1, a kind of folding dining chair mainly comprises wide batten 1, fillet plate 2, rear foot tube 3, adapter 4, seat pipe 5, bolt 6, gangbar 7, stull pipe 8, front foot pipe 9, seat stay pipe 10; It is characterized in that rear foot tube 3 is fixed together by stull 8 pipes and seat stay pipe 10; Wide batten 1 and fillet plate 2 are installed on rear foot tube 3; Hinged adapter 4 on rear foot tube 3, an end of seat pipe 5 is installed on adapter 4, and the other end is fixed together by seat stay pipe 10; Seat pipe upper 5 hinged adapters 4, wide batten 1 and fillet plate 2 set firmly on present pipe 5; One end of front foot pipe 9 is installed on adapter 4, and the other end is fixed together by stull pipe 8; One end of gangbar 7 is hinged on rear foot tube 3, and the other end is hinged on front foot pipe 9.

With reference to Fig. 2, during use, adapter 4 can only move counterclockwise around rear foot tube 3, and can only clockwise rotate around seat pipe 5, after wide batten 1 and fillet plate 2 bear the power of taking a seat, the power of taking a seat is disperseed to rear foot tube 3, seat pipe 5 and front foot pipe 9, at this moment, after front foot pipe 9 is stressed, front foot pipe 9 reaches self-locking state by angle between adapter 4 and seat pipe 5, be that front foot pipe 9 can not be managed 5 around seat and rotated, four connecting rods that form between crus curvilineum pipe 3, seat pipe 5, front foot pipe 9, gangbar 7 this moment are rigidly connected quadric chain, are in the use state after chair is launched.

With reference to Fig. 3, when folding, only need to upwards lift seat pipe 5, be about to seat pipe 5 and rotate counterclockwise around rear foot tube 3, this moment, adapter 4 rotated counterclockwise around rear foot tube 3, under the effect of gangbar 7, four connecting rods that form between crus curvilineum pipe 3, seat pipe 5, front foot pipe 9, gangbar 7 move, drive front foot pipe 9 and clockwise rotate around seat pipe 5, namely adapter 4 clockwise rotates around seat pipe 5, and chair is in folded state.

with reference to Fig. 4, when continuing to fold, continue upwards to lift seat pipe 5, being about to seat pipe 5 rotates counterclockwise around rear foot tube 3, until the wide batten 1 on rear foot tube 3 and fillet plate 2 fit with wide batten 1 and a fillet plate 2 of managing on 5, at this moment, front foot pipe 9 is under the effect of gangbar 7, crus curvilineum pipe 3, seat pipe 5, front foot pipe 9, four connecting rods that form between gangbar 7 continue to move, driving front foot pipe 9 clockwise rotates around seat pipe 5, until the angle between front foot pipe 9 and seat pipe 5 is very little, at this moment, reach the state after folding, the smaller volume of chair, be convenient for carrying and transport.
