Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment, in particular to a leg stretching exercise device. Background Art

[0002] Stretching is a fitness method that can make the coordination between ligaments, muscles and joints smoother and reduce the possibility of injury. It includes active stretching and passive stretching. The so-called active stretching means relying mainly on the strength of contracting muscles rather than other external forces to keep the movement in a certain position. The benefit is that it can increase the flexibility of the movement and the strength of contracting muscles. Leg stretching is a slow and relaxing stretching, and it can also reduce the excitability of nerves and muscles. It is a good method to relax after exercise. Leg stretching can also exercise the legs to strengthen the leg muscles. Using some exercise equipment can improve the effect of leg stretching exercises.

[0003] The existing leg stretching exercise device has the following shortcomings:

[0004] During exercise, leg stretching exercises are generally performed to relax the muscles, thereby preventing muscle injuries during high-intensity exercise. However, among some people who have little experience in exercise, some people's leg stretching posture or strength is not standard, so the stretching effect is very poor and cannot achieve a good stretching effect. In the subsequent exercise process, the stretching preparatory exercise does not meet the standard, which may cause muscle injuries in the subsequent exercise process.

[0005] After stretching and relaxing the legs, sometimes high-intensity leg stretching is performed to exercise the leg muscles. In order to ensure better results during the exercise, specific exercise equipment is needed. However, the operation of existing leg stretching equipment is relatively cumbersome, and during the exercise, other people are required to perform auxiliary training on the side, which increases the difficulty of operation.

[0039] Example 1, as Figure 1-4As shown, when stretching the legs before exercising, the hinge plate A3 is first flipped open. After the hinge plate A3 is no longer blocked, the hinge plate B10 inside the mounting plate A1 is flipped open, and the support rod 2 is flipped out from the inside of the mounting groove 5, so that the support rod 2 is supported inside the card groove 17, thereby fixing the position of the hinge plate B10 and making the hinge plate B10 tilt at a specified angle. Then the user steps on the inside of the groove B12 with the back leg and the inside of the groove A4 with the front leg. During the stretching process, the front leg pushes the hinge plate A3 to move, thereby driving the mounting plate A1 and the base 21 to move. Then the mounting plate A1 drives the slide plate 8 and the mounting plate B7 to move, so that the outer sleeve A15 is stretched. Then, the leg drives the hinge plate A3 to move, which can effectively play a role in the stretching process. During the stretching process, the hinge plate B10 can support the leg, thereby preventing the leg from bending during the stretching process.

[0040] Example 2, as Figure 1-4 As shown, when it is necessary to exercise the legs, first pull the fixing buckle 23 to move the fixing buckle 23, and then drive the inner sleeve rod B26 to move along the outer sleeve B28, so that the spring B27 is extended again, and at the same time the insertion rod 25 is disengaged from the inside of the card hole 24, releasing the fixation of the lock 6, and then the lock 6 is turned over, and then the calf is placed into the inside of the lock 6. When the placement is completed, the fixing buckle 23 is released, and at this time the spring B27 is reset, driving the inner sleeve rod B26 and the fixing buckle 23 to move, so that the insertion rod 25 is reinserted into the inside of the card hole 24, completing After the locking piece 6 is fixed, the calf and thigh are used to push the connecting rod 18 at the same time, and then the connecting rod 18 drives the connecting block A11 to move, so that the outer sleeve A15 slides along the inner sleeve A20 to compress the spring A9. When the calf and thigh no longer apply pressure to the connecting rod 18, the outer sleeve A15 is reset again, and then drives the connecting block A11 and the connecting rod 18 to reset, thereby facilitating the next press. In the process of reciprocating pressure on the connecting rod 18, the user's legs can be effectively exercised.

[0041] Working principle: When stretching the legs before exercising, first flip open the hinged plate A3. After the hinged plate A3 is no longer obstructed, flip open the hinged plate B10 inside the mounting plate A1, and flip out the support rod 2 from the inside of the mounting groove 5, so that the support rod 2 is supported inside the card groove 17, thereby fixing the position of the hinged plate B10 and making the hinged plate B10 tilt at a specified angle. Then the user steps on the inside of the groove B12 with the back leg and the inside of the groove A4 with the front leg. During the stretching process, the front leg pushes the hinged plate A3 to move, thereby driving the mounting plate A1 and the base 21 to move. Then the mounting plate A1 drives the slide plate 8 and the mounting plate B7 to move, so that the outer sleeve A15 is stretched. Then the leg drives the hinged plate A3 to move, which can effectively play a role in the stretching process. During the stretching process, the hinged plate B10 can support the leg, thereby preventing the leg from bending during the stretching process.

[0042] When it is necessary to exercise the legs, first pull the fixing buckle 23 to move the fixing buckle 23, and then drive the inner sleeve rod B26 to move along the outer sleeve B28, so that the spring B27 is extended again, and at the same time the insertion rod 25 is disengaged from the inside of the card hole 24, releasing the fixation of the lock member 6, and then the lock member 6 is turned over, and then the calf is placed inside the lock member 6. When the placement is completed, the fixing buckle 23 is released, and at this time the spring B27 is reset, driving the inner sleeve rod B26 and the fixing buckle 23 to move, so that the insertion rod 25 is reinserted into the inside of the card hole 24, completing the locking. After the fixation of component 6 is completed, the calf and thigh are used to push the connecting rod 18 at the same time, and then the connecting rod 18 drives the connecting block A11 to move, so that the outer sleeve A15 slides along the inner sleeve A20 to compress the spring A9. When the calf and thigh no longer apply pressure to the connecting rod 18, the outer sleeve A15 is reset again, and then drives the connecting block A11 and the connecting rod 18 to reset, thereby facilitating the next press. In the process of reciprocating pressure on the connecting rod 18, the user's legs can be effectively exercised.

[0043] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
