Abstract

The utility model relates to a folding chair, which comprises a flexible chair surface, a seat leg pipe, a back leg pipe, positioning bases, rivets, end sleeves and a transverse stay pipe, and is characterized in that the positioning bases are fixed on the back leg pipe by the rivets; the seat leg pipe, the positioning bases and the back leg pipe are hinged by the rivets; the flexible chair surface is fixed on the seat leg pipe and the back leg pipe; the transverse stay pipe is arranged at the front end of the seat leg pipe; the end sleeves are arranged at pipe orifices of the seat leg pipe; and the positioning bases comprise substrates, extension walls, upper rivet holes, back leg pipe grooves, lower rivet holes, cantilevers and seat leg pipe grooves. Due to the adoption of the structure, the back leg pipe and the seat leg pipe can be positioned relatively by the positioning bases; and a triangular positioning structure which consists of the original metal sheet is removed, so that potential safety hazards caused by shear points are eliminated. The folding chair is simple in structure and convenient to use, and is suitable for resting on occasions such as outdoor travels, sandy beaches and courtyards.

Description

A kind of folding seat

Technical field

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

Background technology

The folding seat of existing cross pipe structure, the location between the cross pipe adopt the sheet metal of a belt length groove to connect usually, constitute variable triangle syndeton; During use, pin joint is at an end of elongated slot, at this moment; The triangle edges that sheet metal constituted is the longest, and under the external force effect in use, a lateral edges of elongated slot has limited the triangle edges that sheet metal constituted and continued to become big; Thereby the triangular support structure that cross pipe and sheet metal are constituted is in firm holding state; When folding, pin joint moves to the opposite side of elongated slot, thereby constantly changes reducing of sheet metal place triangle edges; The triangular structure of being made up of cross pipe and sheet metal changes, and becomes folding volume minimum state until cross pipe.Above-mentioned folding seat occurs shearing point owing to adopted the sheet metal connection in the folding process, easily the operator is damaged, and sheet metal self is thinner, take place more easily to shear injury, so there is potential safety hazard in this structure.To above-mentioned shortcoming, be necessary to make improvement.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of folding seat with connection positioning element of integrative-structure, cancels the sheet metal syndeton in the existing folding seat, thereby has eliminated the problem that has shearing point and cause potential safety hazard.

The utility model solves the technical scheme that its technical problem adopted:

A kind of folding seat mainly comprises flexible seat, seat leg pipe, back of the body pin pipe, positioning seat, rivet, end cover, stull pipe, it is characterized in that positioning seat is fixed on the back of the body pin pipe through rivet; Seat leg pipe, positioning seat, back of the body pin pipe are hinged through rivet; Flexible seat is fixed on the seat leg pipe and carries on the back on the pin pipe; Front end at the seat leg pipe is installed the stull pipe; The installation end envelope at the mouth of pipe place of seat leg pipe.

Described positioning seat mainly comprises pedestal, wall extension, goes up rivet hole, back of the body pin tube seat, rivet hole, cantilever, seat leg tube seat down, it is characterized in that being provided with rivet hole, back of the body pin tube seat, rivet hole down on the pedestal; On pedestal, connect wall extension; On wall extension, be provided with cantilever; Form the seat leg tube seat between wall extension and the cantilever.

Tubular being complementary of the shape of described back of the body pin tube seat and back of the body pin pipe.

The shape of described seat leg tube seat and the tubular of seat leg pipe are complementary.

Be provided with angle between described back of the body pin tube seat and the seat leg tube seat, angle is set its size according to the high needs of seat of folding seat.

Described back of the body pin pipe and seat leg pipe are U type pipe.

The beneficial effect of the utility model is: after adopting said structure; Realize relative positioning through positioning seat between back of the body pin pipe and the seat leg pipe; Cancelled the triangle location structure that the original metallic sheet is constituted; Eliminated the existing potential safety hazard of shearing point, characteristics such as therefore the utlity model has simple in structure, easy to operate, safety and comfort and suitable sandy beach, camp, use during various occasion rest such as garden.

The specific embodiment

Pass through specific embodiment below, and combine accompanying drawing that the technical scheme of the utility model is described further.

Embodiment: with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of folding seat mainly comprises flexible seat 1, seat leg pipe 2, back of the body pin pipe 3, positioning seat 4, rivet 5, end cover 6, stull pipe 7, it is characterized in that positioning seat 4 is fixed on the back of the body pin pipe 3 through rivet 5; Seat leg pipe 2, positioning seat 4, back of the body pin pipe 3 are hinged through rivet 5; Flexible seat 1 is fixed on seat leg pipe 2 and carries on the back on the pin pipe 3; Front end at seat leg pipe 2 is installed stull pipe 7; The installation end envelope 6 at the mouth of pipe place of seat leg pipe 2.

Positioning seat 4 mainly comprises pedestal 41, wall extension 42, goes up rivet hole 43, back of the body pin tube seat 44, rivet hole 45, cantilever 46, seat leg tube seat 47 down, it is characterized in that being provided with rivet hole 43, back of the body pin tube seat 44, rivet hole 45 down on the pedestal 41; On pedestal 41, connect wall extension 42; On wall extension 42, be provided with cantilever 46; Form seat leg tube seat 47 between wall extension 42 and the cantilever 46.

The back of the body pin tube seat 44 that back of the body pin pipe 3 is put into earlier on the positioning seat 4, rivet 5 is through rivet hole 45 and back of the body pin pipe 3 are riveted mutually down then; Rivet 5 passes last rivet hole 43 and the seat leg pipe 2 on back of the body pin pipe 3, the positioning seat 4 successively then, makes the three hinged; Positioning seat 4 has two riveting points with back of the body pin pipe 3, so positioning seat 4 and back of the body pin pipe 3 are for being rigidly connected; Seat leg pipe 2 has only a riveting point with positioning seat 4, so seat leg pipe 2 can rotate around positioning seat 4.

During expansion, rotate seat leg pipe 2, make 3 one-tenth X types of seat leg pipe 2 and back of the body pin pipe; Being rotated further the angle that makes between the two increases; Fit until the tube wall of seat leg pipe 2 and the seat leg tube seat 47 on the positioning seat 4, seat leg pipe 2 and positioning seat 4 relative fixed are because positioning seat 4 is to be rigidly connected with back of the body pin pipe 3; Thereby make seat leg pipe 2, back of the body pin pipe 3 and positioning seat 4 relative fixed, reach the state when launching.

During folding, rotation seat leg pipe 2 diminishes the angle between seat leg pipe 2 and the back of the body pin pipe 3, and the tube wall of seat leg pipe 2 breaks away from the seat leg tube seat 47 on the positioning seat 4 gradually, is rotated further, until seat leg pipe 2 and the 3 approaching coincidences of back of the body pin pipe, the state when reaching folding.

Above-described embodiment is a kind of preferred version of the utility model, is not the utility model is done any pro forma restriction, under the prerequisite that does not exceed the technical scheme that claim puts down in writing, also has other variant and remodeling.
