[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] Example 1

[0029] Reference Figure 1-5 A new type of ergonomic chair comprises a seat 1 and a backrest 2, wherein the backrest 2 is fixed at one end of the top of the seat 1, a plurality of seat rollers are evenly arranged at the bottom of the seat 1, arm support mounting frames 3 are fixed on both sides of the bottom of the seat 1, arm support plates 4 are installed on the tops of the arm support mounting frames 3, and a convenient disassembly and assembly mechanism is installed between the arm support mounting frames 3 and the arm support plates 4, and the convenient disassembly and assembly mechanism is used for connecting the arm support mounting frames 3 and the arm support plates 4.

[0030] The convenient disassembly and assembly mechanism includes a transmission part and a clamping part. A docking tube 5 is fixed to the top of the arm support mounting frame 3, a transmission part is installed on the inner side of the docking tube 5, and a clamping part is installed on the inner side of the transmission part.

[0031] The transmission parts include a movable adjusting rod 6, a sliding groove 7, a limit force plate 8, a connecting spring 9 and a pin seat 10. The movable adjusting rod 6 is slidably connected to one side of the butt joint 5. A sliding groove 7 is provided inside the butt joint 5 and close to the movable adjusting rod 6. The inner side of the sliding groove 7 is slidably connected to the limit force plate 8. The limit force plate 8 is fixed to the movable adjusting rod 6. A connecting spring 9 is fixed to one side of the limit force plate 8. The connecting spring 9 is sleeved on the outer side of the movable adjusting rod 6. One end of the movable adjusting rod 6 passes through the inner side of the butt joint 5 and is fixed with a pin seat 10. When the movable adjusting rod 6 is pressed, the movable adjusting rod 6 drives the limit force plate 8 to squeeze the connecting spring 9 to contract, so that the movable adjusting rod 6 pushes the clamping claw arm 11 to rotate through the pin seat 10, thereby realizing the separation of the clamping claw arm 11 from the anti-slip groove 14.

[0032] The clamping parts include a clamping arm 11, a top seat 12, a docking ring 13 and an anti-slip groove 14. Both ends of the pin seat 10 are rotatably connected to the clamping arm 11 through pins, and the middle part of the clamping arm 11 is rotatably connected to the inner side of the docking tube 5 through pins. The bottom of the arm support plate 4 is fixed with a top seat 12, and the bottom of the top seat 12 is fixed with a docking ring 13. The docking ring 13 is slidably connected to the inner side of the docking tube 5, and the bottom of the docking ring 13 is fixed with a connecting column, and the connecting column is clearance-matched with the inner side of the docking tube 5. Anti-slip grooves 14 corresponding to the end positions of the clamping arm 11 are provided on both sides of the connecting column, and the anti-slip grooves 14 are slidably connected to the clamping arm 11. When the end of the clamping arm 11 is connected to the inner side of the anti-slip groove 14, the connecting column can be vertically limited.

[0033] Rectangular protrusions are integrally fixed on both sides of the docking ring 13, and auxiliary guide grooves 15 corresponding to the positions of the rectangular protrusions are opened on both sides of the top of the docking tube 5. The auxiliary guide grooves 15 are slidably connected to the rectangular protrusions. Through the cooperation between the auxiliary guide grooves 15 and the rectangular protrusions, it is convenient to provide a guiding effect for the docking of the docking tube 5 and the connecting column.

[0034] Example 2

[0035] Embodiment 1 is further optimized, specifically, as Figure 6 As shown, the inner side of the backrest 2 is equipped with a lumbar support mechanism, which is used to support the waist of the user.

[0036] The lumbar support mechanism includes an adjustment cavity seat 16, a force-applying rotating rod 17, a threaded rod 18, an extension head 19 and a lumbar pillow 20. The adjustment cavity seat 16 is fixed on the inner side of the backrest 2, one end of the adjustment cavity seat 16 is rotatably connected to the force-applying rotating rod 17, one end of the force-applying rotating rod 17 is fixed to the threaded rod 18, the outer side of the threaded rod 18 is threadedly connected to the extension head 19, the extension head 19 is slidably connected to the inner side of the adjustment cavity seat 16, and one end of the extension head 19 is fixed to the lumbar pillow 20. When the user sits on the seat 1, the force-applying rotating rod 17 is rotated so that the force-applying rotating rod 17 drives the threaded rod 18 to rotate, and then the extension head 19 moves along the inner side of the adjustment cavity seat 16 until the lumbar pillow 20 is in contact with the user's waist, so that the lumbar pillow 20 supports the user's waist.

[0037] From the above, we can know that:

[0038] The utility model is aimed at the following technical problems: In the process of using the existing technology, the armrest of the seat will be worn by the user's clothes during long-term use, resulting in damage to the top surface, and the smart seat armrest and the seat cushion are fixed, which is not convenient for disassembly and replacement, and there is a certain room for improvement; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0039] During later use, when the top of the arm support plate 4 is severely worn and damaged, the movable adjusting rod 6 is pressed, so that the movable adjusting rod 6 drives the limit force plate 8 to squeeze the connecting spring 9 to contract, and then the movable adjusting rod 6 pushes the clamping claw arm 11 to rotate through the pin seat 10, so that the clamping claw arm 11 is separated from the anti-slip groove 14, and then the arm support plate 4 is removed, replaced with a new arm support plate 4, and the connecting column is inserted into the docking pipe 5, and then the movable adjusting rod 6 is released. At this time, the elastic force generated by the connecting spring 9 pushes the limit force plate 8 to reset and move, and then the movable adjusting rod 6 drives the pin seat 10 to reset and move, so that the pin seat 10 drives the clamping claw arm 11 to rotate until the end of the clamping claw arm 11 is connected to the inner side of the anti-slip groove 14, and finally the arm support plate 4 is replaced.

[0040] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0041] 1. The utility model adopts the structural design of the convenient disassembly and assembly mechanism, so that the device is easy to disassemble and assemble between the arm support frame 3 and the arm support plate 4. When the arm support plate 4 is severely worn, the arm support plate 4 can be quickly replaced without the aid of tools, thereby improving the convenience of the device.

[0042] 2. The utility model uses the structural design of the lumbar support mechanism to enable the device to support the user's waist and adjust the position of the lumbar pillow 20 to facilitate adaptation to users of different body shapes and facilitate use.
