Description

Technical Field

[0001] The utility model relates to the technical field of bamboo chairs, in particular to an anti-deformation bamboo chair. Background Art

[0002] In the agricultural era, our ancestors used bamboo to weave bamboo chairs because bamboo is easy to obtain, has great plasticity, is abundant and cheap, and has a short growth cycle. Bamboo chairs are cooler and more ventilated than modern sofas, and are regarded as a new choice for fashionable home furnishings by people who advocate environmental protection.

[0003] After long-term use, bamboo chairs will become fatigued due to the long-term high pressure, resulting in deformation and reduced stability. The backrests of bamboo chairs are mostly fixed structures and cannot be adjusted according to the user's habits, reducing adjustability. For this reason, we proposed an anti-deformation bamboo chair. Utility Model Content

The top left and right sides of the support frame 110 are provided with through slots 111, and the through slots 111 are used to allow the support legs 120 to pass through. The four corners of the bottom of the seat plate 100 are fixedly connected with support legs 120, and the support legs 120 pass through the through slots 111 and are fixedly connected to the support frames 110, and the support legs 120 are used to support the seat plate 100;

[0025] Please refer again Figure 1-5 The fixed block 200 is fixedly connected to the left side wall of the seat plate 100, and the inner cavity of the fixed block 200 is rotatably connected with a rotating central axis 210, and the rotating central axis 210 is used to drive the backrest 212 to rotate. The rotating central axis 210 passes through the inner cavity of the fixed block 200 and extends to the outside of the fixed block 200. The outer wall of the rotating central axis 210 is fixedly connected with a mounting cylinder 211 on both the front and rear sides, and the mounting cylinder 211 is used to install the backrest 212. The top of the outer wall of the mounting cylinder 211 is fixedly connected with the backrest 212. The top and end of the rotating central axis 210 are fixedly connected with a limiting cylinder 220, and the limiting cylinder 220 is used to limit the rotating central axis 210. The front and rear side walls are respectively provided with limiting holes 221, and are arranged sequentially from left to right. The left sides of the front and rear side walls of the seat plate 100 are fixedly connected with guide rods 230, and the outer side wall of the guide rod 230 is movably connected with a sliding plate 231, and the sliding plate 231 is used to drive the limiting rod 233 to move. The left sides of the front and rear side walls of the seat plate 100 are fixedly connected with coil springs 232, and the coil springs 232 are fixedly connected to the sliding plate 231, and the coil springs 232 are used to push the sliding plate 231 to move and reset. The left sides of the front and rear side walls of the sliding plate 231 are respectively fixedly connected with limiting rods 233, and are arranged sequentially from left to right. The limiting rods 233 are used to limit the limiting cylinder 220.

[0026] To summarize, a support frame 110 is installed. The support frame 110 is triangular in shape and has a larger contact area with the ground at the bottom, so the structure is more stable. Support legs 120 are installed at the four corners of the bottom of the seat plate 100, which can evenly distribute the weight to the bottom of the support frame 110. The support legs 120 pass through the support frame 110 and have threaded holes 121 on the surface. The support legs 120 and the support frame 110 are fixed by bolts, which enhances the stability of the structure, prevents deformation of the structure due to excessive weight, and improves stability.

[0027] Please refer again Figure 1-2 The front and rear side walls of the support frame 110 and the support leg 120 are respectively provided with threaded holes 121 on the left and right sides, and the inner cavities of the threaded holes 121 are screwed with bolts. The threaded holes 121 are used to screw the bolts, thereby fixing the support frame 110 and the support leg 120.

[0028] Please refer again Figure 1-2The bottom of the support frame 110 is fixedly connected with an anti-skid pad 130, and the anti-skid pad 130 is used to prevent the support frame 110 from slipping.

[0029] Please refer again Figure 3 The number of the limiting rods 233 and the limiting holes 221 are the same and they are located on the same horizontal line, so that the limiting rods 233 can be inserted into the limiting holes 221 to limit the limiting tube 220.

[0030] Please refer again Figure 1-3 The end of the guide rod 230 is fixedly connected with an anti-slip plate 234 , and the anti-slip plate 234 is used to prevent the sliding plate 231 from detaching from the guide rod 230 .

[0032] To summarize, the pull ring 240 can be pulled to drive the sliding plate 231 to move on the guide rod 230, thereby driving the limit rod 233 to disengage from the limit hole 221, releasing the restriction on the limit cylinder 220 and the rotating central axis 210, pushing the backrest 212 to make the rotating central axis 210 rotate under force, thereby adjusting the angle of the backrest 212. After loosening the pull ring 240, the spiral spring 232 pushes the sliding plate 231 to reset, so that the limit rod 233 is inserted into the limit hole 221 to complete the limitation of the limit cylinder 220 and the rotating central axis 210, thereby improving the adjustability.

[0033] In specific use, the technical personnel in this field installed a support frame 110, which is triangular in shape and has a larger contact area with the ground at the bottom, making the structure more stable. Support legs 120 are installed at the four corners of the bottom of the seat plate 100, which can evenly distribute the weight to the bottom of the support frame 110. The support legs 120 pass through the support frame 110 and have threaded holes 121 on the surface. The support legs 120 and the support frame 110 are fixed by bolts, which enhances the stability of the structure and prevents deformation of the structure due to excessive weight. By pulling the pull ring 240, the sliding plate 231 is driven to move on the guide rod 230, thereby driving the limit rod 233 to disengage from the limit hole 221, releasing the restriction on the limit cylinder 220 and the rotating central axis 210, pushing the backrest 212 to make the rotating central axis 210 rotate under force, thereby adjusting the angle of the backrest 212. After loosening the pull ring 240, the spiral spring 232 pushes the sliding plate 231 to reset, so that the limit rod 233 is inserted into the limit hole 221 to complete the limitation of the limit cylinder 220 and the rotating central axis 210.
