[0027] The wheels 341 are raised and lowered by the lifting mechanism 2 to control the movement of the toilet body 11 . During the movement, the shock absorbing mechanism 3 is used to absorb the shock of the toilet body 11 to reduce the damage to the toilet body 11 .

[0028] like Figure 2 , Figure 3 As shown, the front part of the inner cavity of the fixed box 21 is fixedly connected with a motor 22, the output end of the motor 22 is fixedly connected with a bidirectional threaded rod 23, the left end of the bidirectional threaded rod 23 is rotatably connected to the left end of the inner cavity of the base 1, the right part of the bidirectional threaded rod 23 is transmission-connected with a transmission belt 24, the rear part of the transmission belt 24 is transmission-connected with a bidirectional threaded rod 25, and the left end of the bidirectional threaded rod 25 is rotatably connected to the left end of the inner cavity of the base 1.

[0029] By starting the motor 22, the bidirectional threaded rod 1 23 is driven to rotate, the bidirectional threaded rod 1 23 drives the transmission belt 24 to rotate synchronously, and the transmission belt 24 drives the bidirectional threaded rod 2 25 to rotate synchronously.

[0030] like Figure 2-Figure 4 As shown, the left and right parts of the outer walls of the bidirectional threaded rod 1 23 and the bidirectional threaded rod 2 25 are both threadedly connected with a slider 1 26 , the bottom end of the slider 1 26 is rotatably connected with a movable rod 28 , and the bottom end of the movable rod 28 is rotatably connected to the top end of the support plate 31 .

[0031] When the two-way threaded rod 1 23 and the two-way threaded rod 25 rotate, the slider 1 26 slides on the outer wall of the two-way threaded rod 1 23 and the two-way threaded rod 25, and the slider 1 26 drives the movable rod 28 to move synchronously, so that the movable rod 28 rotates, and the movable rod 28 drives the support plate 31 to move downward, and drives the wheel 341 to move downward synchronously, so that the bottom end of the wheel 341 contacts the ground, and at the same time, the base 1 and the public toilet body 11 rise upward, achieving a lifting effect.

[0033] When the slider 1 26 slides, it drives the limit block 27 to slide synchronously on the inner wall of the base 1 , and the limit block 27 limits the slider 1 26 , so that the slider 1 26 cannot slide further after sliding to a certain distance.

[0034] like Figure 2 , Figure 5 As shown, the left and right parts of the bottom end of the support plate 31 are fixedly connected to the damper 32, the outer wall of the damper 32 is movably sleeved with a shock-absorbing spring 33, the bottom end of the damper 32 is fixedly connected to the fixing plate 34, and the left and right parts of the bottom end of the fixing plate 34 are fixedly connected to the wheel 341.

[0035] When encountering bumps, the support plate 31 drives the damper 32 and the shock-absorbing spring 33 to contract, thereby absorbing the impact force generated by the bumps, reducing the damage to the toilet body 11 and achieving a shock-absorbing effect.

[0036] like Figure 2 , Figure 5 As shown, a guide rod 35 is fixedly connected to the middle part of the fixed plate 34, a spring 1 36 is movably sleeved on the middle part of the outer wall of the guide rod 35, springs 2 37 are movably sleeved on the left and right parts of the outer wall of the guide rod 35, and a slider 2 38 is slidably connected to the outer wall of the guide rod 35 in a linear array, and the top end of the slider 2 38 is rotatably connected to a support rod 39, and the top end of the support rod 39 is rotatably connected to the bottom end of the support plate 31.

[0037] When a bump occurs, the support plate 31 moves downward, causing the support rod 39 to rotate, and the support rod 39 drives the slider 2 38 to slide on the outer wall of the guide rod 35, causing the spring 1 36 and the spring 2 37 to contract.

[0038] like Figure 2 , Figure 5 As shown, a guide block 381 is fixedly connected to the bottom end of the sliding block 2 38 , and the outer wall of the guide block 381 is slidably connected to the inner wall of the fixed plate 34 , and the outer shape of the guide block 381 is T-shaped.

[0039] When the second slide block 38 slides, it drives the guide block 381 to slide on the inner wall of the fixed plate 34, so that the second slide block 38 slides more smoothly without deviation.

[0040] The working principle of the utility model is as follows: when the main body 11 of the public toilet needs to be moved, the traction hook of the tractor is connected to the towing hook 13, and then the motor 22 is started to drive the two-way threaded rod 23 to rotate, the two-way threaded rod 23 drives the transmission belt 24 to rotate synchronously, and the transmission belt 24 drives the two-way threaded rod 25 to rotate synchronously, thereby making the slider 26 slide on the outer wall of the two-way threaded rod 23 and the two-way threaded rod 25, the slider 26 drives the limit block 27 to slide synchronously on the inner wall of the base 1, and the limit block 27 limits the slider 26, so that the slider 26 cannot continue to slide after sliding to a certain distance, and at the same time, the slider 26 drives the movable rod 28 to move synchronously, so that the movable rod 28 rotates, and the movable rod 28 drives the support plate 31 to move downward, drives the wheel 341 to move downward synchronously, so that the bottom of the wheel 341 The end contacts the ground, and at the same time, the base 1 and the toilet body 11 are raised upward, which has the effect of lifting. When the toilet body 11 is a certain distance away from the ground, the motor 22 can be turned off, thereby making the wheel 341 unable to be recovered. Later, when moving, when bumps occur, the support plate 31 moves downward to rotate the support rod 39, and the support rod 39 drives the slider 2 38 to slide on the outer wall of the guide rod 35, so that the spring 1 36 and the spring 2 37 are contracted. At the same time, the slider 2 38 drives the guide block 381 to slide on the inner wall of the fixed plate 34, so that the slider 2 38 is more stable when sliding, and there is no deviation. At the same time, the support plate 31 drives the damper 32 and the shock-absorbing spring 33 to contract, thereby absorbing the impact force generated during the bumps, reducing the damage to the toilet body 11, and having a shock-absorbing effect, thereby greatly improving the user experience.
