DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a stepping trainer for foot rehabilitation, comprising a bottom plate 1 and a shock absorbing mechanism 2, the shock absorbing mechanism 2 is arranged on one side of the surface of the bottom plate 1, a protective shell 3 is fixedly connected to the upper surface of the shock absorbing mechanism 2, and a clamping mechanism 4 is arranged inside the protective shell 3;

[0021] The shock absorbing mechanism 2 includes a cylinder groove 201, a cylinder barrel 202, a slide 203, a piston rod 204, a sponge layer 205, a connecting plate 206, a first spring 207, a damper 208 and a rubber sheet 209. The cylinder groove 201 is provided on one side of the surface of the bottom plate 1. The cylinder barrel 202 is embedded in the cylinder groove 201. The slide 203 is embedded in the cylinder barrel 202. The piston rod 204 is embedded in the cylinder barrel 202. The sponge layer 205 is attached to one side of the surface of the slide 203. One end of the piston rod 204 is The connecting plate 206 is fixedly connected, the other end of the piston rod 204 is fixedly connected to the first spring 207, the other end of the piston rod 204 is fixedly connected to the damper 208, one end of the damper 208 is connected to the rubber sheet 209, through the arrangement of the cylinder groove 201, the cylinder barrel 202, the sliding plate 203, the piston rod 204, the sponge layer 205, the connecting plate 206, the first spring 207, the damper 208 and the rubber sheet 209, when performing foot training, the downward pressure applied is transmitted through the connecting plate 206 The pressure on the connecting plate 206 is transmitted to the piston rod 204. The piston rod 204 compresses the first spring 207 to deform, and the damper 208 is activated to provide movement resistance. The compression of the first spring 207 and the activation of the damper 208 drive the rubber sheet 209 thereon to press downward. When the rubber sheet 209 presses the sliding plate 203, the sliding plate 203 is pressed downward, and the sponge layer 205 between the two sets of sliding plates 203 is compressed, so that the piston rod 204 is moved in the cylinder. The cylinder 202 is pressed internally, and thereafter when the downward pressure is released, the first spring 207 rebounds and deforms, and the movement resistance of the damper 208 is reversely started, thereby driving the piston rod 204 and the rubber sheet 209 to rebound and deform in the cylinder 202. The rebounding rubber sheet 209 makes the force acting on the slide 203 disappear, thereby driving the slide 203 and the sponge layer 205 to rebound, so that the slide 203 and the sponge layer 205 are reset, and the above process is repeated many times to finally achieve the effect of rehabilitation training.

[0022] Furthermore, the rubber sheet 209 is in contact with the inner wall of the cylinder 202, and the piston rod 204 forms a mutually sliding structure with the cylinder 202 through the first spring 207. Through the setting of the rubber sheet 209, the ends of the first spring 207 and the damper 208 are protected when the inner wall of the cylinder 202 is compressed or rebounded, and the inner wall of the cylinder 202 can also be protected to extend the service life.

[0023] Furthermore, two groups of sliding sheets 203 are provided, and the sponge layer 205 is provided between the two groups of sliding sheets 203. Through the arrangement of the sliding sheets 203 and the sponge layer 205, the sliding sheets 203 provide protection for the rubber sheets 209 when sliding, thereby preventing the rubber sheets 209 from being damaged when too much force is applied. At the same time, the sliding sheets 203 and the sponge layer 205 jointly form a shock-absorbing protective layer to provide protection for the sliding structure on the inner wall of the cylinder 202.

[0024] Furthermore, the other end of the first spring 207 is fixedly connected to the rubber sheet 209, and the damper 208 is arranged inside the first spring 207. Through the arrangement of the first spring 207 and the damper 208, when a force is applied to the piston rod 204, the first spring 207 can effectively degrade the force on the piston rod 204. At the same time, when the force on the piston rod 204 is removed, the first spring 207 can also ensure that the piston rod 204 rebounds normally. The damper 208 can avoid rapid compression or rebound of the structure when the force is applied or removed, thereby increasing the action time, slowing down the force, and ultimately achieving a shock absorbing effect.

[0025] Furthermore, the engaging mechanism 4 includes a foot pedal 401, a mounting groove 402, a pull block groove 403, a limit block 404, a clamping block 405, a second spring 406 and a handle 407. The inside of the protective shell 3 is fixedly connected with the foot pedal 401, the side of the protective shell 3 is provided with a mounting groove 402, the side surface of the protective shell 3 is provided with a pull block groove 403, the inside of the mounting groove 402 is fitted with a limit block 404, one side of the limit block 404 is fixedly connected with the clamping block 405, the other side of the clamping block 405 is fixedly connected with the second spring 406, and the other side of the clamping block 405 is fixedly connected with the handle 407. The pull block slot 403, the limit block 404, the clamping block 405, the second spring 406 and the handle 407 are arranged so that when the foot needs to be placed in the protective shell 3, the handle 407 is pulled, and the handle 407 can pull the clamping block 405 through the pull block slot 403, and the clamping block 405 drives the second spring 406 to compress and deform, and at the same time, the clamping block 405 also drives the limit block 404 to slide inside the installation slot 402, and then the foot is placed on the foot pedal 401, and then the handle 407 is released, and the second spring 406 rebounds and deforms, thereby driving the clamping block 405 to rebound, and the rebound of the clamping block 405 drives the limit block 404 to rebound, thereby achieving the purpose of fixing the foot.

[0026] Furthermore, the block 405 is arranged inside the mounting groove 402, and the second spring 406 is arranged inside the mounting groove 402. The other end of the second spring 406 is fixedly connected to one end of the protective shell 3. Through the arrangement of the block 405 and the second spring 406, after pulling the handle 407, the movement of the block 405 causes the second spring 406 to be compressed and deformed, while driving the movement of the limit block 404, and then the handle 407 is released. At this time, the second spring 406 rebounds and deforms to drive the rebound of the block 405, thereby driving the rebound of the limit block 404, thereby achieving the purpose of fixing the foot.

[0027] Furthermore, the handle 407 passes through one end of the protective shell 3 through the pull block groove 403, and the limit block 404 slides inside the installation groove 402 through the clamping block 405 and the second spring 406. Through the setting of the pull block groove 403, the handle 407 can be perfectly embedded in the pull block groove 403, so that the handle 407 can slide inside the pull block groove 403, thereby enabling the handle 407 to pull the clamping block 405.

[0028] Working principle: first, when putting the foot into the protective shell 3, pull the handle 407, the handle 407 can pull the block 405 through the pull block slot 403, the block 405 drives the second spring 406 to compress and deform, and at the same time, the block 405 also drives the limit block 404 to slide inside the installation slot 402, and then put the foot into the foot pedal 401, then release the handle 407, the second spring 406 rebounds and deforms, thereby driving the block 405 to rebound, and the rebound of the block 405 drives the limit block 404 to rebound, so as to achieve the purpose of fixing the foot, and then perform foot training, the applied downward pressure is transmitted through the connecting plate 206, and the pressure on the connecting plate 206 is transmitted to the piston rod 204, the piston rod 204 presses the first spring 207 to compress and deform, and also causes the damper 208 to start and provide movement resistance, the first spring 20 The compression of 7 and the activation of the damper 208 drive the rubber sheet 209 thereon to press downward. When the rubber sheet 209 presses the slide 203, the slide 203 is pressed downward, and at the same time, the sponge layer 205 between the two groups of slides 203 is compressed, so that the piston rod 204 is pressed inside the cylinder 202. Thereafter, when the downward force is released, the first spring 207 and the first spring 207 rebound and deform, and the damper 208 movement resistance is reversely activated, thereby driving the piston rod 204 and the rubber sheet 209 to rebound and deform in the cylinder 202. The rebounding rubber sheet 209 makes the force acting on the slide 203 disappear, thereby driving the slide 203 and the sponge layer 205 to rebound, so that the slide 203 and the sponge layer 205 are reset, and the above process is repeated many times to finally achieve the effect of rehabilitation training, thereby completing a stepping trainer for foot rehabilitation.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
