Description

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 flexible seat surface, rear foot tube, adapter, seat pipe, bolt, hinged seat, gangbar, right angle Connection Block, front foot pipe, stull pipe, seat stay pipe; The rear foot tube that it is characterized in that a U-shaped setting is fixed together the seat stay pipe by the right angle Connection Block, has formed the quadrilateral frame of rigidity; Set firmly the stull pipe by bolt on rear foot tube, strengthened the cross-brace power of 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 the seat stay pipe by the right angle Connection Block; Flexible seat surface is installed on rear foot tube, seat pipe and seat stay pipe; Upper hinged two adapters that be arranged in parallel of seat pipe, the two ends of the front foot pipe of a U-shaped setting are installed on adapter, and front foot pipe is fixed together the stull pipe by bolt, forms the quadrilateral frame of rigidity; The two ends of two gangbar that be arranged in parallel set firmly hinged seat, and are socketed in respectively on the stull pipe of both sides.

Described adapter is provided with bayonet socket I, draw-in groove, bayonet socket II, hinge hole, locating hole; It is characterized in that rear foot tube or a seat pipe can be placed in draw-in groove by bayonet socket I, bayonet socket II, adapter is hinged by hinge hole and rear foot tube or a seat pipe, and seat is managed or front foot pipe fixes by locating hole and adapter.

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

Described gangbar can be rotated around the stull pipe respectively by hinged seat.

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

The utility model has the advantages that: by flexible seat surface being installed on rear foot tube, seat pipe and seat stay pipe, 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 quadric chain that forms between crus curvilineum pipe, seat pipe, front foot pipe, gangbar is controlled expansion and the folding of chair, therefore the utlity model has simple in structurely, easy to operate, be fit to the sandy beach, camp, the characteristics such as 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, Fig. 2, a kind of folding dining chair mainly comprises flexible seat surface 1, rear foot tube 2, adapter 3, seat pipe 4, bolt 5, hinged seat 6, gangbar 7, right angle Connection Block 8, front foot pipe 9, stull pipe 10, seat stay pipe 11; It is characterized in that rear foot tube 2 is fixed together seat stay pipe 11 by right angle Connection Block 8; Set firmly stull pipe 10 by bolt 5 on rear foot tube 2; Hinged adapter 3 on rear foot tube 2, an end of seat pipe 4 is installed on adapter 3, and the other end is fixed together seat stay pipe 11 by right angle Connection Block 8; Flexible seat surface 1 is installed on rear foot tube 2, seat pipe 4 and seat stay pipe 11; Hinged adapter 3 on seat pipe 4, the two ends of front foot pipe 9 are installed on adapter 3, and front foot pipe 9 is fixed together stull pipe 10 by bolt 5; The two ends of gangbar 7 set firmly hinged seat 6, and are socketed in respectively on the stull pipe 10 of both sides.During use, adapter 3 can only move counterclockwise around rear foot tube 2, and can only clockwise rotate around seat pipe 4, after wide front foot pipe 9 is stressed, front foot pipe 9 reaches self-locking state by angle between adapter 3 and seat pipe 4, and namely when being subject to taking a seat power, front foot pipe 9 can not be managed 4 around seat and be rotated counterclockwise, four connecting rods that form between crus curvilineum pipe 2, seat pipe 4, 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, described adapter 3 is provided with bayonet socket I31, draw-in groove 32, bayonet socket II33, hinge hole 34, locating hole 35; It is characterized in that rear foot tube 2 or seat pipe 4 can be placed in draw-in groove 32 by bayonet socket I31, bayonet socket II33, distance between bayonet socket I31, bayonet socket II33 is less than the caliber of rear foot tube 2 or seat pipe 4, when rear foot tube 2 or seat pipe 4 process bayonet socket I31, bayonet socket II33, utilize the elasticity of adapter 3 self, distance between bayonet socket I31, bayonet socket II33 is increased, until after rear foot tube 2 or seat pipe 4 passed through, bayonet socket I31, bayonet socket II33 sprang back to reset condition; Adapter 3 is hinged by hinge hole 34 and rear foot tube 2 or seat pipe 4, and the setting of draw-in groove 32 after pin pipe 2 or seat pipe 4 enter draw-in groove 32, has limited the rotation of rear foot tube 2 or seat pipe 4; Seat pipe 4 or front foot pipe 9 fix by locating hole 35 and adapter 3.

With reference to Fig. 4, when folding, only need to upwards lift seat pipe 4, being about to seat pipe 4 rotates counterclockwise around rear foot tube 2, this moment, adapter 3 rotated counterclockwise around rear foot tube 2, and under the effect of gangbar 7, four connecting rods that form between crus curvilineum pipe 2, seat pipe 4, front foot pipe 9, gangbar 7 move, drive front foot pipe 9 and clockwise rotate around seat pipe 4, chair is in folded state.

With reference to Fig. 5, when continuing to fold, continue upwards to lift seat pipe 4, until seat pipe 4 and rear foot tube 2 fit, at this moment, front foot pipe 9 is under the effect of gangbar 7, and four connecting rods that form between crus curvilineum pipe 2, seat pipe 4, front foot pipe 9, gangbar 7 continue to move, driving front foot pipe 9 clockwise rotates around seat pipe 4, until the angle between front foot pipe 9 and seat pipe 4 is very little, at this moment, reach the flat form after folding, the smaller volume of chair is convenient for carrying and transports.
