[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0016] Below, the bodybuilding leg press auxiliary device according to the embodiment of the utility model is described with reference to the accompanying drawings. Figures 1 to 3 As shown, the bodybuilding leg-stretching auxiliary device includes a base 1, guide rods 2 and slide grooves 102 are symmetrically provided on both sides of the top of the base 1, a support plate 3 is installed on the guide rod 2, a plurality of supporting plates 4 are fixedly installed on the top of the support plate 3, a lifting component is provided at the bottom of the support plate 3, the supporting plates 4 are equidistantly distributed, a bracket 5 is provided inside the supporting plate 4, and an adjustment component is also provided inside one side wall of the supporting plate 4.

[0017] Preferably, the lifting assembly includes a connecting seat 301, a connecting rod 8 and a slider 9, and there are two of each. The connecting seat 301 is fixedly installed at the bottom of the support plate 3, and the slider 9 is movably installed in the slide groove 102 of the base 1. One end of the connecting rod 8 is hinged to the connecting seat 301, and the other end of the connecting rod 8 is hinged to the top of the slider 9.

[0018] Preferably, a motor 10 is fixedly mounted on one side wall of the base 1, and a bidirectional lead screw 11 is fixedly connected to the output shaft of the motor 10. The bidirectional lead screw 11 is rotatably mounted in two slide grooves 102 through bearings, and the bottom of the slider 9 is movably connected to the bidirectional lead screw 11. By rotating the bidirectional lead screw 11, the two sliders 9 can be driven to move closer to or away from each other in the slide groove 102.

[0019] Preferably, springs 12 are sleeved on both ends of the bidirectional lead screw 11, one end of the spring 12 is connected to the inner wall of the slide groove 102, and the other end is connected to the slider 9. By providing two springs 12, the two sliders can be made more stable when moving in the slide groove 102.

[0020] In a specific embodiment: when it is necessary to adjust the height of the support plate 4, the bidirectional screw 11 is driven to rotate by starting the motor 10. After the bidirectional screw 11 rotates, it will drive the two sliders 9 to move closer to each other in the slide groove 102. At this time, the slider 9 can push up the connecting seat 301 through the action of the connecting rod 8, thereby pulling the support plate 3 to move downward. Because the two ends of the support plate 3 are adaptively connected to the two guide rods 2, the support plate 3 can be made more stable when moving, thereby realizing the adjustment of the height of the support plate 4 according to users of different heights and body shapes, with high flexibility and more practicality.

[0021] Preferably, the adjustment assembly includes a worm gear 6, a worm 7 and a knob 701, and protruding rods are symmetrically provided at both ends of the bracket 5. The two protruding rods are rotatably mounted on the side walls of the supporting plate 4 through bearings, and the worm gear 6 is fixedly connected to the protruding rod on one side of the bracket 5.

[0022] Preferably, the worm 7 is rotatably mounted in the side wall of the supporting plate 4, the worm 7 is meshedly connected with the worm wheel 6, the knob 701 is fixedly mounted on one end of the worm 7, and the surface of the knob 701 is provided with anti-slip grooves.

[0023] In a specific embodiment: when the inclination angle of the bracket 5 needs to be adjusted, the knob 701 is turned to drive the worm 7 to rotate, and the worm 7 drives the worm wheel 6 meshing with it to rotate, and the worm wheel 6 drives the bracket 5 connected to it to rotate, thereby realizing the adjustment of the inclination angle of the bracket 5. At the same time, the self-locking property between the worm wheel 6 and the worm 7 can achieve instant stopping, and the adjustment is more convenient.

[0024] When the user needs to adjust the height of the support plate 4, the motor 10 is started to drive the bidirectional lead screw 11 to rotate. After the bidirectional lead screw 11 rotates, it will drive the two sliders 9 to move closer to each other in the slide groove 102. At this time, the slider 9 can push up the connecting seat 301 through the action of the connecting rod 8, thereby pulling the support plate 3 to move downward. Because the two ends of the support plate 3 are adaptively connected to the two guide rods 2, the support plate 3 can be made more stable when moving, thereby realizing the adjustment of the height of the support plate 4 according to users of different heights and body shapes, with high flexibility and more practicality. When the inclination angle of the support plate 5 needs to be adjusted, the knob 701 is turned to drive the worm 7 to rotate, and the worm 7 will drive the worm wheel 6 meshing with it to rotate, and the worm wheel 6 drives the support 5 connected thereto to rotate, thereby realizing the adjustment of the inclination angle of the support 5. At the same time, the self-locking property between the worm wheel 6 and the worm 7 can achieve immediate stop, and the adjustment is more convenient.
