[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an adjustable leg press trainer includes a base 1 and a bar 7. The top of the base 1 is fixedly connected to two front and rear slide rails 2. The surfaces of the two slide rails 2 are slidably connected to two left and right side support plates 3. The two side support plates 3 are locked in position by locking components 4. The interior of the two side support plates 3 is provided with a sliding groove 5. The inner surface of the two sliding grooves 5 is slidably connected to an assembly component 6. The bar 7 is installed between the two assembly components 6. The exterior of the bar 7 is provided with a protective component 8.

[0024] The locking assembly 4 includes a cross groove 41 formed at the bottom of the side support plate 3. Slots 42 are formed on both the front and back sides of the inner wall of the cross groove 41. First T-shaped blocks 43 are inserted into the interior of each slot 42. Pressure blocks 44 are fixedly connected to the bottom of each of the two first T-shaped blocks 43, and the shape of the pressure blocks 44 matches the shape of the slide rail 2. The two first T-shaped blocks 43 are pressed against the surface of the slide rail 2 to lock the position of the side support plate 3. Two sliding rods 45 are fixedly connected to the side of the side support plate 3. Both slide rods 45 are slidably connected to L-shaped sliders 46. One end of each L-shaped slider 46 is fixedly connected to a second T-shaped block 47, which is an isosceles trapezoid. Both pressure blocks 44 are provided with inclined surfaces, and the inclined surfaces on the pressure blocks 44 cooperate with the inclined surfaces of the second T-shaped blocks 47. A lead screw 49 is rotatably connected to the side of the side support plate 3. A moving block 48 is threadedly connected to the surface of the lead screw 49, and the other end of the moving block 48 is fixedly connected to the second T-shaped block 47.

[0025] The assembly component 6 includes an installation block 61, which has an installation groove 62 inside. Both ends of the single bar 7 are fixedly connected to installation heads 63. The installation head 63 consists of a cylindrical head and a stop bar fixed on the surface of the cylindrical head. The shape of the installation groove 62 matches the installation head 63. A bolt rod 64 is fixedly connected to the back of the installation block 61. The bolt rod 64 passes through the side support plate 3 and extends to the outside of the side support plate 3. A locking sleeve 65 is threadedly connected to the surface of the bolt rod 64 on the outside of the side support plate 3.

[0026] The leg press trainer is designed as a modular structure, which can be quickly disassembled and assembled when transportation or use is required. During assembly, the bar 7 is assembled using the assembly component 6, and the height of the bar 7 can be adjusted up and down. When assembling the side support plate 3, the position of the side plate is locked using the locking component 4, which greatly improves the practicality of the device during use.

[0027] The protective component 8 includes an anti-slip sleeve 81, which is fitted over the outside of the horizontal bar 7. The anti-slip sleeve 81 is cylindrical and is cut horizontally in the middle. Multiple grooves 82 are equally spaced on the upper and lower sections of the anti-slip sleeve 81. Multiple stops 83 that cooperate with the grooves 82 are fixedly connected at equal intervals on the surface of the horizontal bar 7.

[0028] The surface of the horizontal bar 7 is provided with an anti-slip sleeve 81 to protect the user's legs. The design of the groove 82 and the locking block 83 prevents the protective sleeve 81 from rotating when performing leg presses, thereby improving the reliability of the protective component 8 during use.

[0029] During assembly, place the base 1 on the ground and slide the two side support plates 3 onto the slide rail 2 from both sides. Loosen the two locking sleeves 65 and adjust the height of the mounting block 61. Insert the mounting head 63 at one end of the bar 7 into the corresponding mounting slot 62. Move the other side support plate 3 so that the mounting head 63 at the other end of the bar 7 enters the corresponding mounting slot 62. Adjust the two side support plates 3 until they are in the correct position. Rotate the screw 49 and drive the second T-block 47 to move through the moving block 48. The second T-block 47 moves and enters between the two pressure blocks 44, pushing the two pressure blocks 44 away from each other, so that the pressure blocks 44 press against one side of the slide rail 2, thereby locking the position of the side support plate 3. Finally, put the anti-slip sleeve 81 on the outside of the bar 7 and align the groove 82 with the stop block 83.
