The lower end of the plug-in post 23 is in contact with the locking plate 22. The lower end of the plug-in cylinder 24 is fixedly installed inside the fixed cylinder 111. The plug-in post 23 is fixedly installed on the bottom wall of the step plate 12. The lower end of the spring plate 21 is locked to the bottom wall of the base 11, and the upper end of the spring plate 21 is locked to the locking plate 22.
[0032] In this embodiment, when the main body 1 of the device needs to replace the spring sheet 21 after a period of use, the base 11 and the step plate 12 are first separated; then the locking plate 22 is removed, and the spring sheets 21 are taken out one by one from the fixing cylinder 111, and then the new spring sheet 21 is placed back into the fixing cylinder 111; finally, the user re-inserts the slider 122 into the slide groove 112. The operation is simple, the maintenance cost is reduced, and the user is prevented from being injured after the spring sheet 21 fails.
[0033] Specifically, the locking plate 22 has a plurality of first locking posts 221 arranged in a circular pattern, the base 11 has a plurality of second locking posts 113 arranged in a circular pattern inside the fixing cylinder 111, and the upper and lower ends of the spring sheet 21 have first locking holes 211 and second locking holes 212 respectively.

[0034] In this embodiment, the new spring sheet 21 is placed back inside the fixed cylinder 111 to ensure that the first snap-fit post 221 is snapped into the first snap-fit hole 211 and the second snap-fit post 113 is snapped into the second snap-fit hole 212.
[0035] Specifically, the main body 1 of the device also includes an anti-slip pad 13, the upper end face of the step plate 12 has a placement groove 123, the step plate 12 has an installation hole 124 in the inner wall of the placement groove 123, the anti-slip pad 13 is placed in the placement groove 123, the lower end face of the anti-slip pad 13 has an installation post 131, and the installation post 131 is inserted into the installation hole 124.
[0036] Specifically, the main body 1 of the device also includes a fixing rod 14 and a fixing column 15. The anti-slip pad 13 has a through hole 132 on the side wall forming the mounting column 131. The fixing rod 14 is inserted into the through hole 132, and the fixing column 15 is threadedly connected to one end of the fixing rod 14.
[0037] In this embodiment, after the anti-slip mat 13 has been used for a period of time, the user rotates the fixing post 15 to separate the fixing rod 14 from the fixing post 15, and then pulls the fixing rod 14 out of the through hole 132; then, the user can remove the anti-slip mat 13 from the placement groove 123. The operation is simple, the maintenance cost is reduced, and the user is prevented from being injured after the anti-slip mat 13 fails.
[0038] Specifically, the shock absorption mechanism 2 also includes two sets of springs 25. The base 11 has multiple spaced placement cylinders 114 on the bottom wall of the forming groove 112. The step plate 12 has multiple spaced placement holes 125 at the lower end of the forming slider 122. Each set of springs 25 is provided with multiple springs, and each spring 25 is placed between the placement cylinder 114 and the placement hole 125.
[0039] In this embodiment, when the device body 1 needs to replace the spring 25 after a period of use, the user directly removes the spring 25 that has been used for a period of time from the placement tube 114 and puts the new spring 25 back into the placement tube 114.
[0040] Specifically, the base 11 has a moving groove 115 on the side wall forming the sliding groove 112, the step plate 12 has a threaded hole 126 on the side wall forming the slider 122, and the main body 1 of the device also includes a pair of limiting posts 16, one end of which is threadedly connected to the threaded hole 126, and the limiting post 16 extends out of the moving groove 115 by a certain distance.
[0041] In this embodiment, the user inserts the slider 122 into the slide groove 112 and inserts the limiting post 16 into the threaded hole 126 via the moving groove 115, and rotates the limiting post 16 so that the limiting post 16 is threadedly connected to the threaded hole 126.
[0042] The working principle of this utility model is as follows:
[0043] Before use, the user inserts the slider 122 into the slide groove 112 and inserts the limiting post 16 into the threaded hole 126 via the moving groove 115, and rotates the limiting post 16 so that the limiting post 16 is threadedly connected to the threaded hole 126; at this time, the spring 25 is placed between the placement cylinder 114 and the placement hole 125, and the lower end of the insertion post 23 abuts against the locking plate 22.
[0044] During the user's jumping on the footboard 12, the spring plate 21 and spring 25 are continuously stretched and compressed, the slide cylinder 121 slides along the fixed cylinder 111, the plug-in post 23 slides along the plug-in cylinder 24, the slider 122 slides along the slide groove 112, and the limiting post 16 slides along the moving groove 115. In this way, by setting the spring plate 21 and two sets of springs 25, the shock absorption effect is better; and by setting the limiting post 16, the footboard 12 is prevented from separating from the base 11.
[0045] When the main body 1 of the device needs to be replaced after a period of use, the spring plate 21 and the spring 25 are replaced. First, the limiting post 16 is rotated to separate the limiting post 16 from the threaded hole 126. Then, the base 11 and the step plate 12 are separated. Then, the locking plate 22 is removed and the spring plates 21 are taken out from the fixing cylinder 111 one by one. Then, the new spring plates 21 are placed back into the fixing cylinder 111 to ensure that the first locking post 221 is locked into the first locking hole 211 and the second locking post 113 is locked into the second locking hole 212.
[0046] Subsequently, the user directly removes the spring 25, which has been used for a period of time, from the placement cylinder 114 and places the new spring 25 back into the placement cylinder 114; finally, the user re-inserts the slider 122 into the slide groove 112 and then rotates the limiting post 16. The entire replacement process of the spring plate 21 and spring 25 is simple to operate, which helps to reduce maintenance costs and prevents user injury if the spring plate 21 and spring 25 fail.
[0047] When the anti-slip mat 13 needs to be replaced after a period of use, the user rotates the fixing post 15 to separate the fixing rod 14 from the fixing post 15, and then pulls the fixing rod 14 out of the through hole 132; subsequently, the user can remove the anti-slip mat 13 from the placement slot 123. The entire replacement process of the anti-slip mat 13 is simple to operate, which can effectively reduce maintenance costs and prevent user injury caused by the failure of the anti-slip mat 13.
[0048] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
