[0020] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0021] Please see Figure 1-3 According to an embodiment of the present utility model, a self-adjusting spring support device includes a support housing 1, a spring self-adjusting mechanism 2 is installed at the bottom ends of both sides of the support housing 1, and a support mechanism 3 is installed inside the support housing 1.

[0022] In this embodiment, movable grooves 27 are provided at the bottom ends of both sides of the support housing 1. Movable blocks 28 are slidably connected to the movable grooves 27. A motor 4 on the spring self-adjusting mechanism 2 is fixedly installed on the movable blocks 28. A threaded rod 5 is installed at the output end of the motor 4. The threaded rod 5 passes through and is threadedly connected to the first U-shaped plate 6. The first U-shaped plate 6 is fixed on the support housing 1. The second U-shaped plate 7 is slidably connected to both sides of the first U-shaped plate 6. A sliding groove 8 is provided on the side of the second U-shaped plate 7. A slider 9 is fixedly installed on the side of the first U-shaped plate 6 and is slidably connected to the sliding groove 8.

[0023] The first U-shaped plate 6 and the second U-shaped plate 7 slide against each other, the slide groove 8 limits the slider 9, the moving groove 27 limits the moving block 28, and the motor 4 drives the threaded rod 5 to rotate.

[0024] In this embodiment, the second U-shaped plate 7 is fixedly installed on the base plate 10, the bottom of the threaded rod 5 is rotatably connected to the pressure plate 11 through the bearing, the pressure plate 11 and the base plate 10 are fixedly connected to the first buffer 12, and the first buffer 12 is wrapped with the first spring 13.

[0025] When the threaded rod 5 rotates, it moves up and down at the first U-shaped plate 6, thereby driving the pressure plate 11 to move up and down, thus adjusting the elastic force of the first spring 13.

[0026] In this embodiment, an installation cavity 14 is provided at the upper part of the support housing 1, and a buffer cavity 15 is provided below the installation cavity 14. The support mechanism 3 includes a second buffer 16 fixedly installed on the side wall of the installation cavity 14. The end of the second buffer 16 is fixedly connected to a side plate 17. A second spring 18 is fixedly connected between the side plate 17 and the side wall of the installation cavity 14 and wraps around the second buffer 16.

[0027] When the side plate 17 moves left or right, it compresses the second spring 18, which acts as a buffer.

[0028] In this embodiment, the side plate 17 is fixedly connected to the ball 19 by a connecting rod, and the mounting cavity 14 is connected to the baffle 20 by a rotating component. The baffle 20 has a circular hole 21, which is slidably connected to the ball 19.

[0029] Among them, the ball 19 can slide inside the circular hole 21, and the baffle 20 drives the side plate 17 to move through the ball 19.

[0030] In this embodiment, the baffle 20 is rotatably connected to the roller 22, the roller 22 is rotatably connected to the mounting plate 23 through the bearing, the mounting plate 23 is fixedly installed on the support column 24, the third spring 25 is fixedly connected below the mounting plate 23, and the support column 24 has a threaded hole and is threadedly connected to the auxiliary plate 26.

[0031] The equipment is installed on the auxiliary plate 26. The weight of the equipment will cause the support column 24 to descend. At this time, the support column 24 will cause the mounting plate 23 to descend. The mounting plate 23 will cause the roller 22 to descend, thereby squeezing the baffle 20. When the mounting plate 23 descends, it will compress the third spring 25, which will play a buffering role.

[0032] In practical applications, the spring self-adjusting mechanism 2 is first installed in a suitable position via the base plate 10, and the support housing 1 is fixed to the spring self-adjusting mechanism 2. Then, the equipment is installed on the auxiliary plate 26. Due to its weight, the support column 24 will descend, which in turn will cause the mounting plate 23 to descend. The mounting plate 23 will cause the roller 22 to descend, thereby squeezing the baffle 20. When the mounting plate 23 descends, it will compress the third spring 25, which will act as a buffer. The baffle 20 will move the side plate 17 via the ball 19. When the side plate 17 moves left and right, it will compress the second spring 18, which will also act as a buffer. When the weight of the equipment changes, the starter motor 4 will drive the threaded rod 5 to rotate. When the threaded rod 5 rotates, it will move up and down at the first U-shaped plate 6, thereby causing the pressure plate 11 to move up and down to adjust the elasticity of the first spring 13, thus realizing the spring self-adjustment.
