[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0026] A leg press device for physical exercise includes an adjustment module 1, a lifting module 2, a support component 3, and a handle 4;

[0027] The adjustment module 1 includes a lead screw groove 17, a slider 14 is provided in the lead screw groove 17, a connecting rod 13 is fixedly connected to the upper side of the slider 14, one end of a lead screw 15 is movably connected to the inner two ends of the lead screw groove 17, the lead screw 15 is threaded to the slider 14, one end of the lead screw 15 passes through one side of the lead screw groove 17, and one end of the lead screw 15 is fixedly connected to the center of a knob 16. The two ends of the connecting rod 13 are respectively hinged to corresponding connecting rods 12, one end of each of the two connecting rods 12 is respectively hinged to a support plate 11 by a pin, and the lower end of the support plate 11 is hinged to the upper end of the lead screw groove 17 by a pin.

[0028] The lifting module 2 includes two square tubes 21, which are fixedly connected to the lower side of the screw groove 17. The two square tubes 21 are respectively arranged in the corresponding square tubes 22. The two square tubes 21 are threadedly connected to the corresponding screws 23. The lower ends of the two screws 23 are movably connected to the lower side of the corresponding square tubes 22.

[0029] The lower ends of the two lead screws 23 are respectively fixedly connected to the center of the corresponding bevel gear 24. The two bevel gears 24 mesh with the corresponding bevel gears 28. The central shafts of the two bevel gears 28 are respectively movably connected to the corresponding square plates 27. The two square plates 27 are respectively fixedly connected to the corresponding square tubes 22. The end of the central shaft of one bevel gear 28 is fixedly connected to the center of the turntable 25. The center of one bevel gear 28 is fixedly connected to one end of the round rod 26. The other end of the round rod 26 is fixedly connected to the end of the central shaft of the other bevel gear 28. The two square tubes 22 are respectively fixedly connected to both sides of the U-shaped plate 29.

[0030] The support component 3 includes two support plates 31, and the two support plates 31 are respectively fixedly connected to the U-shaped plate 29.

[0031] Each of the two support plates 31 is provided with a corresponding set of mounting holes 32.

[0032] The outer surface of the tray 11 is covered with a rubber material.

[0033] Working principle: The support plate 31 can be installed in a suitable position using a set of bolts through the mounting holes 32, thus fixing the device. When the user needs to exercise their legs, they rotate the turntable 25. The turntable 25 drives one of the corresponding bevel gears 28 to rotate. One of the bevel gears 28 drives another bevel gear 28 to rotate via the round rod 26. This causes the two bevel gears 28 to mesh with their corresponding bevel gears 24, which in turn drive the corresponding lead screws 23 to rotate. The two lead screws 23 then drive the corresponding square tubes 21 to retract along the square tube 22, causing the two square tubes 21 to move the adjustment module 1 downwards, making the height of the support plate 11 suitable for the user. At this point, the turntable 25 is stopped.

[0034] Next, depending on the leg placement position, turn knob 16. Knob 16 drives lead screw 15 to rotate, lead screw 15 drives slider 14 to slide, slider 14 drives connecting rod 13 to move, causing connecting rod 13 to drive corresponding connecting rod 12 to swing. The two connecting rods 12 respectively drive the support plate 11 to swing, moving the support plate 11 to a suitable placement angle. At this point, stop turning knob 16. Then, the user places their legs on the support plate 11 for exercise. The outer surface of the support plate 11 is covered with rubber material, which can increase the user's comfort. At the same time, the contact area between the support plate 11 and the legs is large, reducing pressure and avoiding leg discomfort. This device can adjust the height of the support plate 11 according to actual usage needs and can adjust the placement angle of the support plate 11, making it more practical.

[0035] Beneficial effects: When a user needs to exercise their legs, the height of the support plate 11 can be adjusted to suit the user's height using the lifting module 2. Depending on the position of the legs, the support plate 11 can be moved to a suitable angle using the adjustment module 1. The user can then place their legs on the support plate 11 for exercise. The support plate 11 is covered with rubber material, which can increase the user's comfort. This device can adjust the height of the support plate 11 and the angle of placement of the support plate 11 according to actual usage needs, making it more practical. Example

[0036] This embodiment is a further elaboration based on the first embodiment, wherein the two sides of the lead screw groove 17 are respectively fixedly connected to the symmetrical handles 4.

[0037] Working principle: Based on the first embodiment, the user can hold the handle 4 with both hands to exercise, making it more convenient for the user to exercise.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
