Abstract

The utility model discloses a multitube combination folding chair, it includes the U -shaped pipe, the axle, the cover, the nut, the pin, curve the many U -shaped pipes that big small -size gradient is dwindled with nonrust steel pipe, the round steel board in two mouth of pipe connecting band shaft holes above the U -shaped pipe, the U -shaped pipe is the middle pin hole that is equipped with of pipe violently, many U -shaped pipe box dresses are the flat board together, in the axle penetrates the many above -mentioned shaft holes of U -shaped pipe and overlaps, the suit is in the middle of the axle, two butterfly nuts revolve on two end screw threads on the axle, during the combination, change and lean on two piece outer big U -shapeds to manage crisscross two the chair legs that separately change into downwards, all the other U -shaped pipes interlock and upwards change into the different angle back of the chair, the seat support, the bench is dull and stereotyped, the pin penetrates the back of the chair, the seat support, pins were downthehole in the middle of bench many dull and stereotyped U -shapeds were managed, it decides the fastening of whole U -shaped pipe clamps to screw up two end nuts on the axle. This multitube combination folding chair, nimble the lie seat and the bench that make up into different angles of ability, the breaking becomes dull and stereotyped portable area.

Description

Multitube combination folding chair

Technical field

The utility model relates to a kind of multitube combination folding chair that can be combined into Reclining chairpostures and bench.

Background technology

Do not retrieve correlation technique at present, existing folding, it comprises chair leg, seat support, the chair back, bearing pin etc., and it can become chaise longue and seat, but can not become bench.Tradition collapses volume comparatively greatly, carries inconvenience.

Summary of the invention

Exist can not become bench to overcome traditional folding chair, carry the deficiency of inconvenience, the purpose of this utility model provides one can be combined into Reclining chairpostures and bench, the multitube combination folding chair of Portable belt.

The utility model adopted technical scheme of dealing with problems is: it comprises U-shaped pipe, axle, cover, nut, pin, the many U-shaped pipes that size dimension gradient reduces are curved with stainless steel tube, the round plate of two mouth of pipe connecting band axis holes above U-shaped pipe, pinhole is provided with in the middle of U-shaped pipe transverse tube, many U-shaped pipe boxes are fitted together in dull and stereotyped, axle to penetrate above many U-shaped pipes in axis hole and cover, be sleeved in the middle of axle, two butterfly nuts are spun on axle two end screw thread, turn during combination that outer two large U-shaped pipes are staggered separately changes into two chair legs downwards, all the other U-shaped pipes are staggered upwards changes into the different angles chair back, seat support, change into bench flat board, pin penetrates the chair back, seat support, bench flat board follow in U-shaped pipe intermediate pin sub-aperture more, tighten axle two end nut U-shaped pipe is fixed.This folding chair adopts many U-shaped pipe combinations, can organize flexible combination and become different angles reclining chair, chair back seat support can also be changed into one flat plate, when bench or bed board use.Also because many U-shaped pipe boxes collapse into one flat plate together, volume is very little, thus reach the utility model can be combined into Reclining chairpostures and bench, Portable belt object.

The beneficial effects of the utility model are, can be combined into Reclining chairpostures and bench, also have the little Portable belt of volume.Parts easily manufacture less.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 2 is that the utility model collapses schematic diagram.

In figure 1, U-shaped pipe 2, pin 3, cover 4, axle 5, nut

Detailed description of the invention

In the embodiment shown in Fig. 1,2, curve size dimension gradient reduce many U-shaped pipes 1 with Φ 20mm stainless steel tube, it can be set in together in dull and stereotyped, and volume is very little.U-shaped pipe 1 above two mouths of pipe connects the round plate with axis hole, be provided with a pinhole between transverse tube below at U-shaped pipe 1, axle 4 two termination is provided with screw thread, and axle 4 penetrates in many U-shaped pipe 1 axis holes and cover 3, cover 3 is contained in the middle of axle 4, and two butterfly wing nuts 5 are spun on axle 4 two end screw thread.When being combined into chair or bench, first two, outer limit large scale U-shaped pipe 1 is separately curved two front back legs downwards, all the other U-shaped pipes 1 are the staggered chair back and the seat support upwards separately curving different angles respectively, is combined into chaise longue or seat; Also by the chair back and seat support down tilt, can be combined into bench, pin 2 penetrates in the chair back, seat support, the dull and stereotyped intermediate pin sub-aperture of bench and many U-shaped pipes 1 is worn together and can not be staggered.Tightened by two nuts 5 afterwards and whole U-shaped pipe 1 clamping fixedly secured, this folding employing many U-shaped pipes 1, energy flexible combination becomes the Reclining chairpostures of different angles, can also form bench and use when bed board, collapse into dull and stereotyped Portable belt.

Claims

1. a multitube combination folding chair, it comprises U-shaped pipe, axle, cover, nut, pin, it is characterized in that: curve with stainless steel tube the many U-shaped pipes that size dimension gradient reduces, the round plate of two mouth of pipe connecting band axis holes above U-shaped pipe, pinhole is provided with in the middle of U-shaped pipe transverse tube, many U-shaped pipe boxes are fitted together in dull and stereotyped, axle to penetrate above many U-shaped pipes in axis hole and cover, be sleeved in the middle of axle, two butterfly nuts are spun on axle two end screw thread, during combination, turn that outer two large U-shaped pipes are staggered separately changes into two chair legs downwards, all the other U-shaped pipes are staggered upwards changes into the different angles chair back, seat support, bench is dull and stereotyped, pin penetrates the chair back, seat support, in many U-shaped pipe intermediate pin sub-aperture of bench flat board, tighten axle two end nut whole U-shaped pipe clamp is fastened.
