The trample plate 7 can fall back gradually, so that the weight plate 9 is prevented from falling back quickly for a long distance, legs of a user are protected, the weight plate 9 can stay at any position, and feet cannot be pulled off the trample plate 7 in time when the weight plate 9 is overloaded; meanwhile, the pedal 7 can continuously fall back, so that the leg strength training can keep continuity, the market demand can be met, and the leg strength training device is suitable for popularization. When the lower limb strength training device is used, firstly, a proper number of weight plates 9 are selected to be sleeved on the vertical rods 8, then a user sits on the seat plate 3, backs on the backrest 4 and enables feet to step on the pedal 7, the pedal 7 drives the weight plates 9 to move up and down through the leg stretching and leg bending of the user, the pedal 7 drives the sliding sleeve 6 to move up and down along the sliding rod 5, and therefore lower limb strength training is conducted; when the pedal 7 moves up and down, the sliding sleeve 6 drives the bar-shaped rack 10 to move up and down, when the bar-shaped rack 10 moves up and down, the gear 11 is driven to rotate in the forward direction or in the reverse direction, when the pedal 7 moves up, the gear 11 rotates in the forward direction, at the moment, the gear 11 cannot drive the rotating plate 12 to rotate in the forward direction through the one-way bearing, the gear 11 can freely rotate in the forward direction, and further the pedal 7 does not limit to move up; when the pedal 7 moves downwards, the sliding sleeve 6 is required to drive the strip-shaped rack 10 to move downwards, so that the gear 11 rotates reversely, the rotating plate 12 rotates reversely through the one-way bearing when rotating reversely, the rotating plate 12 drives the baffle 15 to rotate, when the baffle 15 moves to one end of the arc-shaped through groove 14, the rotating plate 12 drives the worm wheel 13 to continue rotating, and the pedal 7 cannot continue moving downwards after moving downwards for a small distance because the worm wheel 13 is meshed and matched with the worm 16 and self-locked between the worm wheel and the worm, and when the worm 16 does not rotate, the worm wheel 13 cannot rotate, so that the pedal 7 stays at a certain height; when a user bends legs to enable the pedal 7 to move downwards, the user presses the control button 18, the driving motor 17 is electrified, a rotating shaft of the driving motor 17 drives the worm 16 to rapidly rotate a vertical shaft, the worm 16 drives the worm wheel 13 to rotate clockwise for a certain angle, the worm wheel 13 rotates clockwise relative to the rotating plate 12, so that the stop lever 15 moves from one end of the arc-shaped through groove 14 to the other end, the user continues to take the legs to enable the pedal 7 to move downwards, the stop lever 15 moves from the other end of the arc-shaped through groove 14 to one end, the pedal 7 cannot continue to move downwards after moving downwards for a certain distance, the pedal 7 is limited, the leg of the user is prevented from being pressed by the pedal 7, the control button 18 is pressed once again, the pedal 7 can continue to move downwards for a certain distance, the process is repeated continuously, and the pedal 7 can gradually fall downwards; when the control button 18 is pressed for a long time, the rotating shaft of the driving motor 17 can drive the worm 16 to rotate rapidly all the time, the worm 16 drives the worm wheel 13 to rotate, the worm wheel 13 drives the rotating plate 12 to rotate through the arc-shaped through groove 14 and the stop lever 15, the pedal 7 can move downwards at the moment, the speed of the pedal 7 moving downwards is controlled, the reverse rotating speed of the gear 11 is only required to be not more than the speed of the reverse rotating of the rotating plate 12, and the pedal 7 can move downwards continuously.

Specifically, as shown in the figure, one side of the pedal 7 in this embodiment is fixedly connected to one end of a first spring rod 20, the bottom of the frame 2 is rotatably connected to the lower end of an upright post 21, the upper end of the upright post 21 is rotatably connected to the lower end of a reciprocating lead screw 22 through a one-way bearing, a nut 23 is installed on the periphery of the reciprocating lead screw 22 in a threaded fit manner, the nut 23 is fixedly connected to the other end of the first spring rod 20, a spiral chute 24 is formed on the periphery of the upright post 21, a slider 25 is installed on the spiral chute 24 in a sliding fit manner, the slider 25 is fixedly connected to one end of a second spring rod 26, and the other end of the second spring rod 26 is fixedly connected to the pedal 7. When the pedal 7 moves up and down, the first spring rod 20 is stretched or compressed, when the pedal 7 moves up, the second spring rod 26 drives the sliding block 25 to move up, the sliding block 25 moves along the spiral chute 24 and drives the upright post 21 to rotate in the positive direction, at this time, the upright post 21 cannot drive the reciprocating screw rod 22 to rotate through the one-way bearing until the sliding block 25 moves to the uppermost end of the spiral chute 24, the reciprocating screw rod continues to move up along with the pedal 7, and the second spring rod 26 starts to be stretched; on the contrary, when the pedal 7 moves downwards, the second spring rod 26 is retracted to the shortest length, and moves downwards along with the pedal 7, the sliding block 25 moves downwards along the spiral sliding groove 24, the upright post 21 starts to rotate reversely, at this time, the upright post 21 drives the reciprocating screw rod 22 to rotate forwards through the one-way bearing, and the screw nut 23 moves upwards and downwards along the reciprocating screw rod 22, so that the first spring rod 20 is stretched or compressed, the elastic force of the first spring rod 20 when stretched can be adjusted, the load force of the pedal 7 is continuously changed in the continuous lifting process, the flexibility during exercise is increased, and the diversity of the training modes is increased.

Specifically, as shown in the figure, the pointer 30 is fixedly installed on one side of the frame 2 according to the embodiment. When the pedal 7 moves up and down, the control sliding sleeve 60 is higher than the pointer 30, and the screw 23 does not move up and down along the reciprocating lead screw 22, so that the elastic force of the first spring rod 20 is not changed any more when being stretched.

Further, as shown in the drawings, the slide rod 5 of the present embodiment is fixedly installed with a stop ring 40, and the bottom side of the sliding sleeve 6 is in contact fit with the top side of the stop ring 40. When the bottom side of the slide bush 6 is in contact engagement with the top side of the stopper ring 40, the pedal 7 is moved to the lowermost side.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
