Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, and particularly relates to a flexibility training device for sports. Background Art

[0002] Before physical exercise, people will enhance the stretching ability of ligaments and muscles through flexibility training to promote blood circulation and prevent sports injuries caused by overly tight muscles. Bending backward is a relatively common movement for flexibility training before physical exercise. It requires standing with feet apart and shoulder-width apart, raising both arms upward, arching the hips, and leaning the upper body backward until the head is down and both palms touch the ground, with the whole body in an arch shape. During the process of bending backward, the height of the waist will gradually decrease. Most of the existing backward bending trainings are assisted by training rods in the stadium. Since the training rods are fixed at a fixed height by screws, the support height of the waist cannot be reduced during the backward bending process, nor can it adapt to trainers of different heights, resulting in a poor user experience. In severe cases, it may even cause damage to the waist of the trainer. Moreover, most of the support members used in the existing training devices do not have the function of adjusting the support arc. The support members with a single arc obviously cannot adapt to trainers in different backward bending amplitudes, greatly reducing the comfort during training. Therefore, it is necessary to design a flexibility training device for sports that can adapt to trainers of different heights and whose support arc is adjustable. Content of the Utility Model

[0003] The purpose of the utility model is to provide a flexibility training device for sports, which solves the problems that the existing training devices are not suitable for trainers of different heights and the support arc cannot be adjusted.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] A flexibility training device for sports, including a bottom plate. A support telescopic rod is arranged on the upper surface of the bottom plate. The top of the support telescopic rod is connected with a support plate. An elastic support member for supporting the human body during sports flexibility training is arranged on the support plate. A chute is opened on the support plate. A first slider is arranged in the chute, and the first slider is connected with a first electric telescopic rod for driving the first slider to slide along the chute. One end of the elastic support member is fixed on the support plate, and the other end is connected to the first slider. The cross-section of the elastic support member is arc-shaped and forms a support space with the support plate. A support air cylinder barrel for supporting the elastic support member is arranged inside the support space.

[0006] Furthermore, it also includes a foot limiting component. The foot limiting component is composed of a limiting frame and a guide rail. The limiting frame is slidably connected to the guide rail through a second slider, and the guide rail is fixedly connected to the upper surface of the bottom plate.

[0007] Further, the top of the support cylinder is hinged to an elastic support member, and the support cylinder includes an upper cylinder, a lower cylinder, and a counterweight block arranged in sequence from top to bottom. The counterweight block contacts the support plate under the action of gravity. The upper cylinder is slidably arranged inside the lower cylinder, and a sealed gas storage space is formed between them. The gas storage space is provided with an air inlet hole and an air outlet hole. A one-way valve for admitting gas into the gas storage space is arranged in the air inlet hole, and the air outlet hole is connected to a solenoid valve through a pipeline.

[0008] Further, the support telescopic rod is a second electric telescopic rod, a controller is arranged on the bottom plate, and the second electric telescopic rod, the first electric telescopic rod, and the solenoid valve are all connected to a remote control device through the controller.

Specific implementation manner

[0018] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] As Figure 1-5 shown, a flexibility training device for sports includes a bottom plate 1. A support telescopic rod 2 is arranged on the upper surface of the bottom plate 1. The top of the support telescopic rod 2 is connected to a support plate 3. An elastic support member 4 for supporting the human body during sports flexibility training is arranged on the support plate 3. A chute is formed on the support plate 3. A first slider is arranged in the chute, and the first slider is connected to a first electric telescopic rod 14 for driving the first slider to slide along the chute. One end of the elastic support member 4 is fixed on the support plate 3, and the other end is connected to the first slider. The cross-section of the elastic support member 4 is arc-shaped and forms a support space with the support plate 3. A support cylinder for supporting the elastic support member 4 is arranged inside the support space.

[0020] Working principle: The elastic support member 4 can be made by, but not limited to, a method of arranging steel sheets in silicone or rubber. A leather layer can be arranged at the part of the elastic support member 4 that contacts the waist of the trainer, which is comfortable and easy to clean. When using this device for training, the support telescopic rod 2 can be adjusted to a suitable use height to match trainers of different heights. Two groups of chutes can be arranged on both sides of the elastic support member 4 respectively. It is only necessary to connect the first slider in one of the chutes to the first electric telescopic rod 14. Since the length of the elastic support member 4 is fixed and one end is fixed on the support plate 3, after the first electric telescopic rod 14 drives the first slider to slide along the chute, the other end of the elastic support member 4 can follow the first slider to slide. Therefore, sliding the elastic support member 4 can adjust the arc height of its cross-section. The support cylinder should be able to maintain the support effect after the arc height of the cross-section of the elastic support member 4 changes.

[0021] Preferably, it further includes a foot limiting component, which is composed of a limiting frame 11 and a guide rail 12. The limiting frame 11 is slidably connected to the guide rail 12 through a second slider. The guide rail 12 is fixedly connected to the upper surface of the bottom plate 1. The foot limiting component is used to limit the feet during lower back exercises and is preferably arranged at the fixed end of the elastic support member 4. Without adjusting the height of the support telescopic rod 2, the distance between the foot limiting component and the elastic support member 4 can be kept fixed. The limiting frame 11 is used to place the feet, which is convenient for hooking the toes to achieve a stable effect. By sliding the limiting frame 11 on the guide rail 12, it can adapt to trainers of different heights and improve the adaptability of the device.

[0022] Preferably, the top of the support cylinder is hinged to the elastic support member 4, and the support cylinder includes an upper cylinder 5, a lower cylinder 6 and a counterweight 7 arranged in sequence from top to bottom. The counterweight 7 contacts the support plate 3 under the action of gravity. The upper cylinder 5 is slidably arranged in the lower cylinder 6 and a sealed air storage space is formed inside the two. The air storage space is provided with an air inlet hole 8 and an air outlet hole 9. A one-way valve for inflating the air storage space is arranged in the air inlet hole 8. The air outlet hole 9 is connected with a solenoid valve 10 through a pipeline. The above scheme is a specific implementation manner of the support cylinder, in which the model of the solenoid valve 10 is 0927200. After sliding the elastic support member 4 to a higher arc height, since the counterweight 7 contacts the support plate 3 under the action of gravity, the length of the support cylinder elongates, and the internal air storage space becomes larger. The support cylinder intakes air through the one-way valve air inlet hole 8 and can maintain the support effect. When the elastic support member 4 is slid to a lower arc height: since the support cylinder hinged to the bottom of the elastic support member 4 will be subjected to the pressure from the trainer's waist, by opening the air outlet hole 9 through the solenoid valve 10, the gas in the air storage space will slowly be discharged through the air outlet hole 9, the length of the support cylinder shortens, and the counterweight 7 contacts the support plate 3 under the action of gravity, and the support cylinder can still maintain the support effect. Therefore, the support cylinder should be able to maintain the support effect after the arc height of the cross section of the elastic support member 4 changes. Several support cylinders are provided, and preferably at least three are provided.

[0023] Preferably, the support telescopic rod 2 is a second electric telescopic rod. A controller is arranged on the bottom plate 1. The second electric telescopic rod, the first electric telescopic rod 14 and the solenoid valve 10 are all connected to a remote control device through the controller. The model of the controller is STC15F104W. The remote control device can be a wireless remote control switch. By controlling the second electric telescopic rod, the first electric telescopic rod 14 and the solenoid valve 10 through the remote control device, even a single person can independently complete the training, improving the convenience of using the device.

[0024] Preferably, a support strip plate 13 is provided at the bottom of the bottom plate 1. Threaded through holes are vertically penetrated through the four corners of the bottom plate 1. The threaded through holes are penetrated with threaded rods 15. The bottom of the threaded rod 15 is rotatably connected with universal wheels 16. The top of the threaded rod 15 can be fixedly connected with a rotating cap for easy rotation. When training, by rotating the rotating cap to rotate the threaded rod 15, the universal wheels 16 can be made higher than the support strip plate 13. When the training device needs to be moved, by rotating the rotating cap to rotate the threaded rod 15, the universal wheels 16 can be made lower than the support strip plate 13, and the device can be supported and moved by the universal wheels 16. The device can be moved by adjusting the height of the universal wheels 16, further improving the convenience of the device.

[0025] Preferably, a limiting plate 17 is provided at the same height of the threaded rod 15 on the bottom plate 1. The limiting plate 17 is used to ensure that the universal wheels 16 at the four corners of the bottom of the bottom plate 1 can maintain the same height after adjustment.

[0026] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
