[0002] At present, running underwater is also a form of exercise. Since the buoyancy of water reduces the gravity on the body, the pressure on the joints is greatly reduced, which effectively reduces the damage to the leg joints caused by running. At the same time, underwater running is also a very suitable recovery exercise measure for people with joint or muscle injuries. Some professional athletes or people who need to do health care have adopted cross-training methods such as underwater running; on the other hand, the resistance of water is much greater than the resistance of air, and the calories consumed are also greatly increased, which is very suitable for people who want to lose weight.

[0051] In at least one embodiment, the adjustment hole 122 includes a sliding area 123 and a limiting area 124; wherein the sliding area 123 is arranged along the curved surface of the adjustment portion 12 toward the end of the adjustment portion 12 close to the handle 111 and is roughly semi-spiral, and the sliding rod 16 is slidably connected to the sliding area 123 of the adjustment hole 122. During the sliding process of the sliding rod 16, under the action of the adjustment hole 122, the transmission rod 14 drives the sliding mechanism 2 to slide in a lifting manner. wherein the limiting area 124 is connected to the end of the sliding area 123 close to the handle 111, and the limiting area 124 is used to limit the sliding of the sliding rod 16, and the limiting area 124 is arranged to extend along the sliding direction of the vertical transmission rod 14.

[0052] When in use, the adjusting portion 12 rotates relative to the sliding portion 15, and the sliding rod 16 slides in the sliding area 123 of the adjusting portion 12 to adjust the height of the sliding rod 16. At the same time, the sliding rod 16 drives the sliding portion 15 to slide in the accommodating cavity 121 of the adjusting portion 12, and the sliding rod 16 slides to the limiting area 124. The limiting area limits the sliding of the sliding rod 16, and the sliding portion 15 is in an ascending state. During the sliding process of the above-mentioned sliding portion 15, the sliding portion 15 causes the transmission rod 14 to drive the sliding mechanism 2 to slide, so that the locking assembly 3 locks the box body 102 and the box door 101.

[0053] Figure 5 for Figure 2 In some embodiments, reference Figure 2 and Figure 5 The sliding mechanism 2 includes at least one lifting rod 22 and a plurality of limiting frames 21. The plurality of limiting frames 21 are arranged on the groove wall of the receiving groove 103 of the box body 102 close to the box door 101, and the plurality of limiting frames 21 are spaced evenly from the top to the bottom of the box body 102, so that the lifting rod 22 can slide through the fixing frame 13 and the plurality of limiting frames 21. The lifting rod 22 is close to one end of the transmission rod 14 and a connecting portion 141 is fixed on the side wall of the lifting rod 22 away from the box door 101, and the connecting portion 141 protrudes outward toward the end away from the box door 101; and the connecting portion 141 is hinged to one end of the transmission rod 14 away from the sliding portion 15.

[0054] In some embodiments, reference Figure 2 and Figure 5, the limiting frame 21 is arranged as a steel frame formed by steel sheets or steel bars surrounding the lifting rod 22, so as to facilitate the sliding of the lifting rod 22 within the limiting frame 21. The limiting frame 21 includes, but is not limited to, one of a "U" shape, a semi-circular shape, a dovetail shape, an arc shape with an opening on one side, or other semi-closed shapes with an opening on one side, and the limiting rod is arranged in a shape adapted to the limiting rod.

In at least one embodiment, refer to Figure 5 And Figure 6 , the limiting frame 21 is generally in a "U" shape, and the lifting rod 22 is generally in a cuboid shape; a sliding groove 221 is provided along the length direction of the side of the lifting rod 22 away from the box door 101, and a slider 211 adapted to the sliding groove 221 is fixed on the limiting frame 21, wherein the slider 211 is slidably connected to the sliding groove 221; during use, the sliding groove 221 of the lifting rod 22 is slidably connected to the slider 211 to facilitate the smooth sliding of the lifting rod 22.

[0056] In some embodiments, refer to Figure 6 , the locking assembly 3 includes a plurality of locking rods 31 and a plurality of locking hooks 32. A plurality of locking hooks 32 are fixed on the box door 101 at equal intervals along the sliding direction of the lifting rod 22. First through holes 222 adapted to the locking hooks 32 are provided in the lifting rod 22. A second through hole (not shown in the figure) identical and corresponding to the first through hole 222 is provided in the groove wall of the accommodating groove 103 of the box body 102 close to the box door 101 side. The sliding groove 221 of the lifting rod 22 communicates with the first through hole 222 and the second through hole. After the box door 101 is closed, the locking hook 32 sequentially passes through the second through hole of the box body 102, the first through hole 222 of the lifting rod 22, and the sliding groove 221 of the lifting rod 22, and a predetermined distance is left between the locking hook 32 and the hole wall of the first through hole 222 along the sliding direction of the lifting rod 22 to reserve space for installing the locking rod 31.

[0057] In at least one embodiment, refer to Figure 5 And Figure 6 , the locking rod 31 is adapted to the locking hook 32, and a sealing member is provided on the box door 101. The locking hook 32 passes through the sealing member and is fixed on the box door 101. Among them, the locking rod 31 passes through the lifting rod 22 along the direction perpendicular to the sliding direction of the lifting rod 22, and a predetermined distance is left between the locking rod 31 and the locking hook 32 along the sliding direction of the lifting rod 22, so that the locking rod 31 is disengaged from the locking hook 32, thereby enabling the locking hook 32 to disengage from the first through hole 222 and the second through hole. When the lifting rod 22 slides upward, the locking rod 31 and the locking hook 32 are engaged to lock the box door 101. On the contrary, when the lifting rod 22 slides downward, the locking rod 31 and the locking hook 32 are disengaged, and the locking hook 32 disengages from the first through hole 222 and the second through hole, and the box door 101 can be opened.

In some other embodiments, the limiting members include but are not limited to locking caps 311 or other elements that limit the locking rod 31 from being separated from the locking holes 223, and both ends of the locking rod 31 are threadedly connected to the locking caps 311.

[0059] During installation, the locking rod 31 is inserted into the locking hole 223 and abuts against the hole wall of the locking hole 223 away from the locking hook 32. The two ends of the locking rod 31 are threadedly connected to the locking cap 311. When the lifting rod 22 rises and slides, the locking rod 31 is engaged with the locking hook 32, and the locking cap 311 changes height along with the lifting rod 22. The arrangement of the locking cap 311 facilitates the removal of the locking rod 31 by removing the locking cap 311, thereby facilitating the subsequent removal of the lifting rod 22 from the box body 102.

[0060] According to the implementation principle of one or more embodiments of the present application:

[0061] When in use, the user enters the treadmill body 100, then closes the door 101, and the lock hook 32 is inserted into the second through hole of the box body 102 and the first through hole 222 of the lifting rod 22. The handle 111 is further rotated, and the adjustment part 12 rotates with the handle 111, and the adjustment hole 122 of the adjustment part 12 causes the sliding rod 16 to slide from the sliding area 123 to the limiting area 124, and the sliding part 15 drives the transmission rod 14 to slide upward.

[0062] Then, the transmission rod 14 drives the lifting rod 22 to slide upward. During the sliding of the lifting rod 22, the locking rod 31 moves along with the lifting rod 22 toward the end close to the locking hook 32, and the slider 211 of the limit frame 21 and the slide groove 221 of the lifting rod 22 slide with each other to increase the sliding smoothness of the lifting rod 22.

[0063] Finally, the locking rod 31 is engaged with the locking hook 32, thereby facilitating the locking of the door 101 and the box body 102. After the user has finished using the treadmill, the user turns the handle 111 in the opposite direction, and the locking rod 31 is disengaged from the locking hook 32, so that the door 101 can be opened and the treadmill body 100 can be left.
