Description

Bamboo chair

TECHNICAL FIELD The present invention relates to the field of chairs, and is mainly a bamboo chair.

Background Art The current bamboo chair is manufactured by using two kinds of materials, wood or plastic, but it is not strong in actual use for various reasons, and there is a problem that the chair is rocked back and forth. Say

Summary of the invention

The purpose of the present invention is to solve the above disadvantages of the prior art and to provide a bamboo chair.

Book

The technical solution adopted by the utility model. The bamboo chair mainly comprises a rear chair leg, a front chair leg and a seat cushion, and the rear chair leg and the front chair leg are fixedly connected by a lower connecting rod and an upper connecting rod, and the upper connecting rod comprises an upper connecting rod steel pipe. The upper connecting rod steel tube has two ends exposed at two ends and is fixedly connected in the rear chair leg and the front chair leg steel pipe; the lower connecting rod includes a lower connecting rod steel pipe, wherein the lower connecting rod steel tube has two ends exposed at both ends and is fixedly connected to the rear chair Inside the steel tube of the foot and the front chair, the bottom surface of the lower connecting rod is a flat surface.

The rear chair foot mainly comprises a rear chair foot cover frame, a rear steel pipe frame and a rear connection frame. The seat cushion is provided with a front clamp and a rear clamp, and the rear connection frame is provided with a rear connection frame card which is engaged with the rear clamp. The front chair foot mainly comprises a front connecting frame, a front chair foot cover frame and a front steel pipe frame, and the front connecting frame is provided with a front connecting frame card slot which is engaged with the front clamping piece; the upper connecting rod steel pipe and the lower connecting rod steel pipe The casing structure is formed on the rear steel pipe frame and the front steel pipe frame.

The length direction of the rear chair foot and the front chair foot is outwardly disposed at an angle between the vertical direction.

The beneficial effects of the utility model are as follows: The product adopts a casing joint structure, and no screw is fixed. The longer the casing, the smaller the inner and outer swings, which greatly reduces the shaking of the chair back and forth. This product can be overlapped and the steel frame is reinforced in the frame to ensure sufficient strength.

DESCRIPTION OF REFERENCE NUMERALS: seat cushion 1, front clamp 1-1, rear clamp 1-2, lower connecting rod 2, lower connecting rod steel tube 2-1, upper connecting rod 3, upper connecting rod steel tube 3-1, rear chair foot 4 , rear chair foot frame 4-1, rear steel frame 4-2, rear connecting frame 4-3, rear connecting frame slot 4-4, front chair foot 5, front connecting frame 5-1, front chair foot frame 5-2, front steel pipe frame 5-3, front connecting frame card slot 5-4. DETAILED DESCRIPTION OF THE INVENTION The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in the figure, the bamboo chair mainly comprises a rear chair leg 4, a front chair leg 5 and a seat cushion 1, and the rear connecting leg 4 and the front chair leg 5 pass between the lower connecting rod 2 and the upper connecting rod 3 Fixed connection, the upper connecting rod 3 comprises an upper connecting rod steel tube 3-1, wherein two ends of the upper connecting rod steel tube 3-1 are exposed and fixedly connected in the steel tube of the rear chair foot 4 and the front chair foot 5; the lower connecting rod 2 The lower connecting rod steel pipe 2-1 is included, wherein the two ends of the lower connecting rod steel pipe 2-1 are exposed and fixedly connected in the steel pipe of the rear chair foot 4 and the front chair foot 5. The rear chair foot 4 mainly comprises a rear chair foot frame 4-1, a rear steel pipe frame 4-2 and a rear connecting frame 4-3, and the seat cushion 1 is provided with a front clamp 1-1 and a rear clamp 1-2, The connecting frame 4-3 is provided with a rear connecting frame slot 4-4 which is engaged with the rear clip 1-2; the front chair foot 5 mainly comprises a front connecting frame 5-1, a front chair foot frame 5-2 and The front steel frame 5-3, the front connecting frame 5-1 is provided with a front connecting frame slot 5-4 which is engaged with the front clip 1-1; the upper connecting rod steel tube 3-2 and the lower connecting rod steel tube 2-2 2 The casing structure is formed on the rear steel pipe frame 4-2 and the front steel pipe frame 5-3.

Working principle: The rear side of the rear chair foot 4 and the front chair foot 5 are disposed at an angle to the outside, so that a plurality of chairs can overlap, and the bottom surface of the lower connecting rod 2 is a plane. When the two chairs are overlapped, the lower connecting rod 2 and the surface of the seat cushion 1 increase the force receiving area, thereby reducing the degree of surface scratching. The steel pipe inside the lower connecting rod 2 and the upper connecting rod 3 is lengthened, and the two ends of the steel pipe are exposed outside, and the two ends are inserted into the rear leg 4, the rear steel pipe frame 4-2 and the front steel pipe in the front chair foot 5 respectively. In the steel pipe on the frame 5-3, the inner and outer diameters of the steel pipe have a small gap fit, and function as a sleeve. The longer the casing, the smaller the swing probability. When assembling, a small amount of metal glue can be applied to the inner and outer surfaces to fill the small gap with glue to achieve a joint effect.

In addition to the above-described embodiments, the present invention may have other embodiments. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
