Detailed Embodiment

[0018] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present utility model.

[0019] A leg trainer for dance practice, as Figures 1-5 shown, includes a base 1, a seat 2, a rotating shaft 3, a gear 4, a support plate 5, a limiting rod 6, a handle 7 and a rack 8. The seat 2 is fixedly connected to the top of the base 1, and the user can sit on the seat 2 for leg training. Two rotating shafts 3 are rotatably connected to the bottom of the seat 2. The two rotating shafts 3 are symmetrically arranged front and back. The rotating shafts 3 are fixedly connected with gears 4 and support plates 5 respectively. The legs of the user are respectively placed on the corresponding support plates 5. Limiting rods 6 are fixedly connected to one side of the two support plates 5 close to each other. The handle 7 is slidably connected to the top of the base 1. The handle 7 is located between the front and rear support plates 5. Two racks 8 are fixedly connected to the bottom of the handle 7. The two racks 8 are located on the front and rear sides of the handle 7. The racks 8 are engaged with the corresponding gears 4.

[0020] When the user needs to perform leg training, manually pull the handle 7 to the left to engage the rack 8 with the gear 4, so that the gear 4 rotates. The rotation of the gear 4 drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the support plate 5 to rotate in a direction away from each other, so as to perform crotch-opening training on the user. After the crotch-opening training is completed, manually pull the handle 7 to the right to engage the rack 8 with the gear 4, so that the gear 4 rotates in reverse. The reverse rotation of the gear 4 drives the rotating shaft 3 to rotate in reverse. The reverse rotation of the rotating shaft 3 drives the support plate 5 to rotate in a direction close to each other, so that the limiting rods 6 contact each other, preventing the support plate 5 from rotating excessively and causing the rack 8 to disengage from the gear 4. This leg trainer needs to manually pull the handle 7 for crotch-opening training and does not require a traction rope for leg training, greatly increasing the service life of this leg trainer.

[0021] As Figure 1 and Figure 2 shown, it further includes a first block 9 and a second block 10. The bottoms of the two racks 8 are fixedly connected with the first blocks 9 respectively. The first blocks 9 are symmetrically arranged front and back. The second blocks 10 are fixedly connected to the top of the base 1. The two second blocks 10 are symmetrically arranged front and back. When pulling the handle 7 to the left to move the racks 8 to the left, the first blocks 9 at the bottoms of the racks 8 also move to the left. When the first block 9 moves to the left and contacts the second block 10, the handle 7 cannot be moved further to the left. At this time, the maximum rotation angle of the support plate 5 is reached. The first block 9 and the second block 10 can prevent the handle 7 from being pulled too far and causing the rack 8 to disengage from the gear 4.

[0022] As Figure 1 , Figure 4 and Figure 5As shown in the figure, it further includes a fixed rod 51, a fixed seat 11, a guide rod 12, an elastic member 13, a slider 14 and a wedge block 15. Fixed rods 51 are fixedly connected to the bottom of the support plate 5. The two fixed rods 51 are symmetrically arranged front and back. Two fixed seats 11 are fixedly connected to the top of the base 1. The fixed seats 11 are symmetrically arranged front and back. Two guide rods 12 are fixedly connected to the top of each fixed seat 11. Sliders 14 are slidably connected to the side of the guide rods 12 close to the seat 2. Elastic members 13 are fixedly connected between the sliders 14 and the top of the fixed seats 11. The elastic members 13 are arranged as helical springs. Wedge blocks 15 are fixedly connected to the top of the sliders 14. The inclined surfaces of the wedge blocks 15 face right. When the handle 7 is pulled to the left to rotate the support plate 5, the fixed rod 51 will contact the inclined surface of the wedge block 15 and squeeze the wedge block 15, causing the front and rear sliders 14 to slide along the guide rods 12, and the elastic members 13 are squeezed. After continuing to rotate the support plate 5, the fixed rod 51 is located on the left side of the wedge block 15 and no longer squeezes the inclined surface of the wedge block 15. The elastic members 13 return to their original state, causing the front and rear sliders 14 to slide and reset along the guide rods 12. After releasing the handle 7, the user retracts their legs, causing the front and rear support plates 5 to approach each other, so that the fixed rod 51 contacts the left side of the wedge block 15, thereby being able to block the reset of the support plate 5 and maintaining the user's straddle position for leg straddle training.

[0023] As Figure 1 , Figure 4 and Figure 5 shown in the figure, it further includes an electric push rod 16 and a pull plate 17. Two electric push rods 16 are fixedly connected to the top of the base 1. The two electric push rods 16 are symmetrically arranged front and back. Pull plates 17 are fixedly connected to the push rods of the electric push rods 16. The pull plates 17 are located at one end close to the corresponding sliders 14. When the user's legs are fatigued and it is inconvenient to move the sliders 14, by controlling the retraction of the push rods of the two electric push rods 16, the pull plates 17 contact the sliders 14 and move the sliders 14 away from the user, so that the wedge blocks 15 no longer contact the fixed rods 51, releasing the fixed state of the support plate 5. Then, by moving the handle 7 to the right, the support plate 5 can be slowly reset. After the user's leg training is completed, it is convenient for the user to disengage from this leg training device.

[0024] As Figure 1 , Figure 4 and Figure 5 shown in the figure, it further includes an emergency button 18. Emergency buttons 18 are fixedly connected to the left sides of the electric push rods 16. The emergency buttons 18 are electrically connected to the electric push rods 16. The emergency buttons 18 are close to the front and rear sides of the seat 2. When the user uses this leg trainer for straddle training, if an accident occurs to the user, pressing the emergency button 18 will control the retraction of the push rod of the electric push rod 16, thereby being able to release the fixation of the support plate 5 and prevent the user's legs from being injured.

[0025] AsFigure 1 , Figure 3 and Figure 5 As shown in and

[0026] , it further includes universal wheels 19. A universal wheel 19 is installed at the bottom of each side of the support plate 5 away from the seat 2. When moving the support plate 5, the universal wheels 19 will move along the rotation trajectory of the support plate 5 to provide support for the support plate 5, thereby reducing the friction between the rack 8 and the gear 4, making it more labor-saving, and extending the service life of the gear 4 and the rack 8.

[0026] The above embodiments are only preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
