This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "disposed" on another element, it can be directly disposed or attached to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

As shown in figure 1, the folding bamboo chair comprises a seat plate 1, a chair back 2, handrails 3, supporting legs 4 and a footrest 5, the tops of the two supporting legs 4 on each side are rotatably connected, a multi-groove buckle 6 is arranged at the middle position of the bottom of each handrail 3 and is connected with the tops of the two supporting legs 4, a connecting shaft 7 at the top of each supporting leg 4 is positioned in the multi-groove buckle 6, the two ends of the seat plate 1 are respectively connected with the chair back 2 and the footrest 3 in a shaft mode, and a multi-stage self-locking telescopic rod 8 is arranged between the middle of each side of the footrest 3 and the middle of one supporting leg 4.

As shown in fig. 2 to 5, the multi-stage self-locking telescopic rod 8 includes a housing 9, a pulling rod 10, a sliding block 11 and a hook plate 12, the housing 9 is hollow and is provided with ten tooth sockets 14 connected with the same through groove 13, both ends of the through groove 13 are longer than the distribution area of the tooth sockets 14, one end of the pulling rod 10 is inserted into the housing 9, the end of the pulling rod is provided with a J-shaped groove 15, the hook plate 12 is embedded into the J-shaped groove 15, the overall size of the pulling rod is smaller than that of the J-shaped groove 15, the hook plate 12 is provided with a vertical clamping column 16, a first spring 17 in a compression state is further arranged between the hook plate 12 and the J-shaped groove 15, the sliding block 11 is integrally in a shape like a Chinese character 'kou', the inner side of the sliding block is provided with a step 18, the outer side of the sliding block 11 is provided with the pulling rod 10.

The folding bamboo chair is characterized in that a first beam 21 is arranged on the chair back 2, a second beam 22 and a third beam 23 are arranged on the seat plate 1, a fourth beam 24 is arranged on the footrest 5, the folding bamboo chair comprises an integrated bamboo piece bearing pad 26 connected through a soft belt 25, the two ends of the folding bamboo chair are respectively connected with the first beam 21 and the fourth beam 24, and the second beam and the third beam are used for supporting the bearing pad 26.

Two bamboo bearing pads connected through soft belts are arranged on the chair back 2 and the chair plate 1, one is arranged between the first beam 21 and the third beam 23, and the other is arranged between the third beam 23 and the fourth beam 24.

While the foregoing embodiments show a specific multi-stage adjustable telescopic rod, it is obvious that the structural member may be replaced by other devices having telescopic and locking functions. Similarly, the multi-groove buckle depicted in the drawings is five grooves, and can be replaced by three to eight grooves in practical application as required.

The working principle of the invention is as follows: the multi-stage self-locking telescopic rod is arranged between the footrest and the supporting legs, so that the lifting angle of the footrest can be adjusted according to needs when the footrest is used, and the footrest is high in adaptability. The multi-stage self-locking telescopic rod is convenient to adjust and stable and reliable in structure. The multistage auto-lock telescopic link that the embodiment was described can realize does: when the drawing rod 10 is pulled leftwards (in the direction of the drawing), each tooth pitch (the distance between tooth grooves 14) is pulled, under the action of the first spring 17 and the tooth grooves 14, the clamping column 16 jumps from one tooth groove 14 to the next tooth groove, the clamping column 16 cannot jump out when the drawing rod 10 is pushed reversely, and the angle adjustment is to adjust the number of the tooth pitches of the jumping of the clamping column. Card post 16 can drive slider 11 when removing and remove, when the card post gets into logical groove 13 left end portion, reach multistage auto-lock telescopic link's longest state, push away pole 10 right again, then card post 16 gets into step 18 of slider 11 (the broken line marks the card post position in figure 4), when continuing to remove, card post card 16 is in step 18 department, can't kick-back, be located logical groove 13 all the time, can be fast with taking out the disposable furthest of pole and inserting the shell, reach multistage auto-lock telescopic link's shortest state, take out pole 10 again to the left pulling, perhaps stimulate taking out pole 10 left midway, the slider is because of receiving the friction of second spring 20 with the shell 9 inner wall, the card post leaves the step, get into the tooth's socket.

The embodiments of the present invention are described only for the preferred embodiments of the present invention, and not for the limitation of the concept and scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the design concept of the present invention shall fall into the protection scope of the present invention, and the technical content of the present invention which is claimed is fully set forth in the claims.
