[0002] With the increasing awareness of fitness among the general public, people are constantly raising their requirements for the scientific and targeted nature of fitness. As a classic exercise for strengthening lower limb strength and core stability, squats occupy an important position in fitness training. However, there are significant differences in height, leg length, body proportions, and athletic ability among different fitness enthusiasts, and traditional fixed-height squat machines cannot meet the diverse needs.

[0003] Place your feet at the bottom of two symmetrically arranged foam tubes, with the back of your calves on one side of the backrest. Train your legs by leaning back and bending your legs. Place the resistance band on the squat machine and around the trainee's waist to train your waist.

[0004] Existing squat machines are not convenient for adjusting the height of the board behind the knees. Since the lower leg lengths of trainees of different heights are different, they are not suitable for a wider range of trainees. At the same time, it is also inconvenient to install elastic bands on the squat machine. Therefore, a height-adjustable squat machine is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a height-adjustable squatting machine.

[0016] (III) Beneficial Effects

[0017] This invention provides a height-adjustable squat machine. It has the following beneficial effects:

[0018] 1. The lifting mechanism facilitates the adjustment of the height of the insertion post, thus adapting to training for different calf lengths. Manually pull the fixing pin outwards from the inside of the insertion post, hollow post, and U-shaped plate in sequence. The fixing pin moves the limiting ring, which compresses the spring. Then, manually pull the insertion post upwards to adjust its height. After adjusting, release the tension on the fixing pin. Under the action of the spring, the limiting ring pushes in the opposite direction, pushing the fixing pin into the corresponding circular hole and fixing the insertion post. This mechanism allows for height adjustment of the insertion post, improving training comfort for the trainee.

[0019] 2. The snap-fit ​​mechanism facilitates the installation of the elastic rope in the squat machine. Manually pressing one end of the inclined surface of the pressing rod causes it to rotate downwards around the pivot point within the elliptical hole. This stretches the tension spring, bringing the inclined surface of the pressing rod into contact with the top of the fixed base plate. The elastic rope is positioned on the opposite side of the fixed rod and base plate. Releasing the tension on the pressing rod causes the inclined surface of the pressing rod to rise upwards under the action of the tension spring, contacting the inclined surface of the fixed rod. This confines the elastic rope to the opposite side of the fixed rod and base plate, facilitating the installation of the elastic rope. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a height-adjustable squatting machine, including a fixed base plate 1, a lifting mechanism 2 provided on the top of the fixed base plate 1, and a snap-fit ​​mechanism 3 symmetrically provided on the top of the fixed base plate 1.

[0030] The lifting mechanism 2 includes a hollow column 201 fixedly installed on the top of the fixed base plate 1. The hollow column 201 has an inner liner block 206 inside, and the inner liner block 206 has a plug-in column 202 installed inside.

[0031] Specifically, the inner liner 206 is fixedly installed inside the hollow column 201, and the round protrusion on one side of the inner liner 206 is locked inside the hollow column 201. The insertion post 202 can move up and down inside the inner liner 206, thereby adjusting the height of the insertion post 202.

[0032] A number of circular holes 205 are evenly distributed on one side of the plug-in post 202, and a U-shaped plate 203 is installed on one side of the hollow post 201. A fixing pin 204 is provided inside the U-shaped plate 203.

[0033] Specifically, the fixing pin 204 is movably inserted into the inside of the U-shaped plate 203, and the fixing pin 204 is also movably inserted into the inside of the hollow column 201. Inserting one end of the fixing pin 204 into the corresponding circular hole 205 has the function of fixing the insertion column 202.

[0034] A limiting ring 208 is fixedly installed on the outer surface of the fixing pin 204. A spring 207 is provided on one side of the limiting ring 208, and the spring 207 is located on the outside of the fixing pin 204.

[0035] Specifically, when the fixing pin 204 is manually pulled out from the inside of the circular hole 205, the fixing pin 204 drives the limiting ring 208 to move outward. The limiting ring 208 applies a certain pressure to the spring 207, causing the spring 207 to deform. After the insertion post 202 is pulled upward to adjust to a certain height, the tension applied to the fixing pin 204 is released. Under the action of the spring 207, the limiting ring 208 is pushed in the opposite direction, thereby inserting the fixing pin 204 into the corresponding circular hole 205.

[0036] The fixing pin 204 is adapted to several circular holes 205 and is movably inserted into the inside of the circular holes 205. One side of the limiting ring 208 is located on one side of the hollow column 201.

[0037] Specifically, when the plug-in post 202 is pulled upward, it will cause several circular holes 205 to move simultaneously. After the plug-in post 202 moves to a suitable height, the fixing pin 204 is inserted into the corresponding circular hole 205, which has the function of fixing the plug-in post 202.

[0038] Furthermore, manually pull the fixing pin 204 outward, causing the fixing pin 204 to move the limiting ring 208. Pull out one end of the fixing pin 204 that was inserted into the circular hole 205. Manually pull the plug-in post 202 upward inside the inner liner block 206. After adjusting to a suitable height, under the action of the spring 207, push the limiting ring 208 in the opposite direction. The limiting ring 208 pushes the fixing pin 204 in the opposite direction into the corresponding circular hole 205, thus stabilizing the plug-in post 202 in the inner liner block 206.

[0039] Example 2

[0040] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a snap-fit ​​mechanism 3 for facilitating the installation of the elastic rope.

[0041] The snap-fit ​​mechanism 3 includes a first grip 301 and a second grip 302 symmetrically installed on the top of the fixed base plate 1. A fixing rod 303 is fixedly installed on the outer surface of the first grip 301, and a pressing rod 304 is provided inside the second grip 302.

[0042] Specifically, the fixed rod 303 and the pressing rod 304 each have a 45-degree inclined surface on their opposite sides, and the inclined surfaces of the two are compatible. The end of the pressing rod 304 with the inclined surface can be rotated downward around the pivot inside the second grip 302, which makes it easy to place the elastic rope used for training on the opposite side of the fixed rod 303 and the fixed base plate 1.

[0043] The outer surface of the second grip 302 has an elliptical hole 305, and the top of the fixed base plate 1 is symmetrically provided with side plates 306. A tension spring 307 is fixedly installed on the top of the fixed base plate 1.

[0044] Specifically, when the pressing rod 304 rotates on the opposite side of the two side plates 306 via the pivot, the pressing rod 304 flips downward around the pivot inside the elliptical hole 305, and the pressing rod 304 stretches the tension spring 307. After the elastic rope is placed on the opposite side of the fixed rod 303 and the fixed base plate 1, the inclined surfaces of the pressing rod 304 and the fixed rod 303 are pressed together under the action of the tension spring 307.

[0045] The pressing rod 304 is placed in the inner cavity of the elliptical hole 305. The pressing rod 304 is rotatably connected to the opposite side of the two side plates 306 via a rotating shaft. The other end of the tension spring 307 is fixedly connected to the pressing rod 304.

[0046] Furthermore, manually press one end of the inclined surface of the pressing rod 304. The pressing rod 304 rotates downward around the pivot in the inner cavity of the elliptical hole 305. At this time, the tension spring 307 is stretched, and the inclined surface of the pressing rod 304 contacts the top of the fixed base plate 1. The elastic rope is placed on the opposite side of the fixed rod 303 and the fixed base plate 1. The tension applied to the pressing rod 304 is released. Under the action of the tension spring 307, the inclined surface of the pressing rod 304 contacts the inclined surface of the fixed rod 303, and the elastic rope is restricted to the opposite side of the fixed rod 303 and the fixed base plate 1.

[0047] Working principle: When leg training is required, the trainee places their feet under the two sponge tubes and rests the back of their knees against the insertion post 202. Training is performed by leaning back and bending the knees. To adjust the height of the lifting mechanism 2, the fixing pin 204 is manually pulled outwards, moving out of the circular hole 205. As the fixing pin 204 moves, it drives the limiting ring 208 outwards, applying a certain tension to the spring 207. At this time, the insertion post 202 is pulled upwards. After adjusting the height of the insertion post 202, the tension on the fixing pin 204 is released. Under the action of the spring 207, the spring 207 pushes the limiting ring 208 in the opposite direction, causing the fixing pin 204 to move in the opposite direction. When the limiting ring 208 contacts the hollow post 201, the fixing pin 204 is inserted into the corresponding circular hole 205, thus completing the insertion of the insertion post 202. The height of the 2nd adjustment is sufficient for leg training. For waist training, manually press down on one end of the inclined surface of the pressing rod 304. The pressing rod 304 is located on the rotating shaft on the opposite side of the two side plates 306. Rotate the pressing rod 304 so that one end of the inclined surface contacts the top of the fixed base plate 1. At this time, the end of the pressing rod 304 stretches the tension spring 307, placing the elastic rope on the opposite side of the fixed rod 303 and the fixed base plate 1. Release the pressure applied to the pressing rod 304. At this time, under the action of the tension spring 307, the pressing rod 304 flips in the opposite direction around the rotating shaft, so that the inclined surface of the pressing rod 304 contacts the inclined surface of the fixed rod 303, thus fixing the elastic rope on the opposite side of the fixed rod 303 and the fixed base plate 1. After fixing the elastic rope with the other pressing rod 304 in the same way, the trainee faces upward and holds the first grip 301 or the second grip 302, placing the elastic rope around the waist for training.
