[0019] In summary, the present invention has the following advantages:

[0020] 1. The utility model provides a load-bearing component. After the user sits on the seat cushion, the seat cushion is subjected to pressure and squeezes the load-bearing spring, so that the seat cushion encounters resistance when moving downward, thereby buffering the pressure on the seat cushion for the first time. At the same time, the load-bearing top plate moves downward after being subjected to pressure, and the fixed plate moves downward, and is acted upon by the supporting spring to buffer the pressure for the second time. At the same time, in the process of the load-bearing top plate moving downward, the load-bearing top plate will approach the load-bearing fixed plate, so that the height of the long plates abutting each other is reduced, thereby causing the support shaft to move downward. Under the action of the spring rod, the load-bearing top plate is supported and buffered, thereby buffering the pressure for the third time. The pressure is effectively supported through three buffering steps, thereby improving the load-bearing effect of the device.

[0021] 2. The utility model sets a load-bearing component. During the process of the load-bearing top plate descending, the long plates abutting each other support the support shaft under the supporting force of the spring rod, so that the sliding seat supports the bottom of the load-bearing top plate in multiple directions under the action of the long plates, the movable seat and the support shaft, thereby dispersing the pressure on the top of the load-bearing top plate, reducing the pressure on the four sides of the load-bearing top plate, and reducing the situation where the pressure is concentrated in the middle of the load-bearing top plate. At the same time, the fixed plate and the support spring support the middle of the load-bearing top plate, thereby improving the load-bearing capacity of the device.

[0032] The load-bearing component is used to improve the load-bearing capacity of the leisure chair. The load-bearing component includes a load-bearing top plate 7 and a load-bearing fixed plate 8. The load-bearing fixed plate 8 is sleeved on the outside of the support column 16. The four corners of the bottom of the load-bearing fixed plate 8 are fixedly connected with support strips. The bottom of the support strip is fixedly connected to the top of the support plate 17 to ensure the stability of the load-bearing fixed plate 8 when working. The top of the load-bearing top plate 7 is fixedly connected with load-bearing springs at equal intervals. The top of the load-bearing spring is fixedly connected to the top of the inner wall of the installation groove. The bottom of the load-bearing top plate 7 is evenly spaced with sliding grooves. The inside of the sliding groove is slidably connected to two sliding seats 9. The bottom of the sliding seat 9 is rotatably connected to a long plate 10. The two long plates 10 abutting each other are rotatably connected through a support shaft 11 to support. Both ends of the shaft 11 are rotatably connected to fixed blocks, and the bottom of the fixed block is fixedly connected to a spring rod 12. The spring rod 12 includes a sleeve, and the inside of the sleeve is slidably connected to a piston rod. One side of the piston rod and one side of the inner wall of the sleeve are connected by a small spring, which is used to buffer and support the support shaft 11. The bottom end of the long board 10 is rotatably connected to a movable seat 13. The movable seat 13 and the sliding seat 9 both include a U-shaped block. The inside of the U-shaped block is fixedly connected to a short rod, and the outside of the short rod is provided with a ring. The surface of the ring is fixedly connected to one end of the long board 10 to ensure the normal rotation of the long board 10. Moving grooves are evenly spaced at the top of the load-bearing fixed plate 8. The movable seat 13 is slidably arranged inside the moving groove, and a height adjustment component is installed at the bottom of the load-bearing top plate 7.

[0033] The height adjustment component is used to adjust the height of the leisure chair. The height adjustment component includes a fixed plate 14 fixedly connected to the bottom of the load-bearing top plate 7, an adjusting column 15 is slidably connected inside the fixed plate 14, and a sliding plate is fixedly connected to the top of the adjusting column 15. A limiting groove is provided inside the fixed plate 14, and the sliding plate is slidably arranged inside the limiting groove to limit the moving range of the adjusting column 15. The top of the adjusting column 15 is connected to the top of the inner wall of the fixed plate 14 by a supporting spring, and the outer side of the adjusting column 15 is slidably connected to the support column 16. Two limit blocks are fixedly connected to the outside of the column 15, and vertical grooves for the movement of the limit blocks are provided on both sides of the inner wall of the support column 16, ensuring the normal movement of the adjusting column 15. Threaded openings are evenly spaced on the surface of the adjusting column 15, and mounting holes are provided on the surface of the support column 16. Bolts that are compatible with the threaded openings are installed inside the mounting holes, which is convenient for fixing and limiting the adjusting column 15 and the support column 16. The bottom of the support column 16 is fixedly connected to a support plate 17, and moving wheels are installed at the four corners of the bottom of the support plate 17 to facilitate the movement of the device.

[0034] The implementation principle of a high-load-bearing leisure chair in the embodiment of the present application is: when the leisure chair needs to adjust the angle of the backrest 3, the rotating rod 4 is rotated, so that the first bevel gear 5 drives the second bevel gear 6 to rotate, thereby causing the support rod to rotate with the backrest 3, thereby realizing the adjustment of the angle of the backrest 3. After the adjustment is completed, the threaded rod is inserted into the inside of the limit mouth to ensure the stability of the rotating rod 4.

[0035] After the user sits on the seat cushion 1, the seat cushion 1 is subjected to pressure and will squeeze the load-bearing spring, so that the seat cushion 1 encounters resistance when moving downward, thereby buffering the pressure on the seat cushion 1 for the first time, and at the same time, the load-bearing top plate 7 moves downward after being subjected to pressure, and the fixed plate 14 moves downward, and is acted upon by the supporting spring to buffer the pressure for the second time. At the same time, in the process of the load-bearing top plate 7 moving downward, the load-bearing top plate 7 will approach the load-bearing fixed plate 8, so that the height of the long plates 10 abutting each other is reduced, thereby causing the support shaft 11 to move downward, and under the action of the spring rod 12, the load-bearing top plate 7 is supported and buffered, thereby buffering the pressure for the third time. The pressure is effectively supported through three buffering steps, thereby improving the load-bearing effect of the device.

[0036] During the descending process of the load-bearing top plate 7, the four groups of long plates 10 abutting each other support the four support shafts 11 under the supporting force of the spring rods 12, so that the four groups of sliding seats 9 support the four directions of the bottom of the load-bearing top plate 7 under the action of the four groups of long plates 10, the four groups of movable seats 13 and the four support shafts 11, thereby dispersing the pressure on the top of the load-bearing top plate 7, reducing the pressure on the four sides of the load-bearing top plate 7, and reducing the situation where the pressure is concentrated in the middle of the load-bearing top plate 7. At the same time, the fixed plate 14 and the support spring support the middle of the load-bearing top plate 7, thereby improving the load-bearing capacity of the device.

[0037] When the height of the leisure seat needs to be adjusted, first turn the bolt to release the connection between the adjustment column 15 and the support column 16, then lift the adjustment column 15 upward, adjust it to the appropriate position, and then turn the bolt again to connect the adjustment column 15 and the support column 16 together, thereby achieving the height adjustment of the leisure seat.

[0038] In addition, the same or similar reference numerals are used whenever possible in the drawings and description to refer to the same or similar parts or steps. The drawings are presented in simplified form and are not drawn to exact scale. For convenience and clarity only, directional terms such as top, bottom, front, rear, left, right, front, back, upward, above, above, below, below, rear, and front may be used with respect to the drawings. These and similar directional terms should not be construed as limiting the scope of this disclosure in any way.
