Description

Technical Field

[0001] The invention belongs to the technical field of sports protection, and in particular relates to an auxiliary device for preventing joint sports injuries. Background Art

[0002] Exercise is a key factor in maintaining good health. Regular exercise can enhance cardiopulmonary function, promote blood circulation, improve muscle strength and flexibility, help control weight and reduce the risk of chronic diseases. Exercise also has a positive impact on mental health, relieving stress and anxiety, and enhancing self-confidence and happiness.

[0003] If the exercise intensity is too high, the movements are not standardized or there is a lack of proper warm-up, it may cause excessive pressure on the joints, resulting in injuries. On the other hand, with age, the mobility of the joints will also decrease, and the degeneration of the bone surface makes the joints more vulnerable to injury. In addition, some diseases such as rheumatism and arthritis may also increase the risk of joint injuries, so it is necessary to prevent injuries caused by joint movement.

[0004] Currently, joint injuries are usually prevented by using knee pads and straps to fix and limit joint movement to ensure that the joints are in the correct position. When standing, walking or performing heavy physical activities for long periods of time, knee pads and straps can help keep the knees stable by fixing and supporting the knee joints, thereby reducing the stress and slippage of the knee joints and avoiding knee injuries due to position displacement or excessive movement. However, existing protective equipment is difficult to adapt to different users and its preventive effect is insufficient, so it needs to be improved and optimized. Summary of the invention

[0021] When performing sports exercises that require frequent use of the knee joint, the user tears the Velcro 3 off the patch 4, ties the upper strap 1 to the thigh, ties the lower strap 1 to the calf, and adjusts them to a comfortable position according to the user, then fits the Velcro 3 and the patch 4 together to complete the wearing. At this time, the user can start the motor 21, and the fixing frame 12 drives the reciprocating screw 22 to rotate. Further, the piston plate 23 reciprocates back and forth along the reciprocating screw 22. When the piston plate 23 moves forward, the plug 10 does not move, and the plug 2 16 is pumped by the air pressure inside the inflation chamber 7, causing the spring 2 19 to be compressed. At this time, the outside air will enter the inflation chamber from the air inlet pipe 14 to the inflation chamber. Inside the air chamber 7, when the piston plate 23 moves backward, the plug 16 will be reset by the elastic potential energy of the spring 19, and further, the plug 16 will block the baffle 15 to prevent the gas from escaping. At this time, the piston plate 23 will push the air stored in the air chamber 7 into the inflation port 9, and the plug 10 will compress the spring 13 downward, and further air will be filled into the interior of the airbag 6 from the inflation port 9. The above working process is repeated, and the airbag 6 will gradually expand, so that the strap 1 and the user's leg are completely fitted and a certain pressure is applied. Then the user stops the motor 21 and starts exercising. At this time, the complete fit of the strap 1 and the partial pressure applied can improve the stability of the joint.

[0022] Through the operation of the motor 21, the piston plate 23 starts to reciprocate. Further, the piston plate 23 will move forward to draw the outside air into the interior of the inflation chamber 7, and when it moves backward, the air inside the inflation chamber 7 will be pumped into the interior of the airbag 6 to achieve inflation. Compared with the traditional device, the device can make the strap 1 and the leg fit completely during the wearing process, disperse the pressure on the joints during exercise, and apply pressure to the legs through the airbag 6 to fix the joint position, prevent the joints from being injured due to excessive movement during exercise, and improve the prevention effect.

[0023] Wherein, slots 30 are provided on the right sides of the two sets of straps 1; A fixing plate 26 is fixedly installed inside the slot 30 of the lower binding strap 1 , a fixing shaft 27 is fixedly installed on the top of the fixing plate 26 , and a movable plate 29 is fixedly installed inside the slot 30 of the upper binding strap 1 .

At this time, the torsion spring 28 will absorb the force of the user squatting, and when the user stands up, the torsion spring 28 will assist the user in straightening his joints through its elastic potential energy.

[0025] Through the elastic potential energy of the torsion spring 28, when the user's joints are bent, the resistance received is greater, thereby preventing damage caused by rapid bending of the joints. When the user's joints are straightened, the elastic potential energy of the torsion spring 28 assists the user to stand up, reduces the pressure on the joints, reduces the burden on the user, improves the prevention effect, and protects the joints.

[0026] Among them, an air inlet pipe 14 is fixedly installed on the side of the inflation chamber 7, a baffle plate 15 is fixedly installed inside the air inlet pipe 14, and a fixing frame 17 is fixedly installed inside the air inlet pipe 14.

[0027] When the piston plate 23 moves forward, the air inlet pipe 14 draws external air into the interior of the air charging chamber 7 .

[0028] Among them, a partition plate 20 is fixedly installed inside the inflation chamber 7, and the partition plate 20 is located below the piston plate 23 and is responsible for preventing the piston plate 23 from falling off.

[0029] By setting the reciprocating screw rod 22, the piston plate 23 is blocked by the partition plate 20 when it moves to the bottom, so as to prevent it from falling off.

[0030] A motor 21 is fixedly installed inside the air filling chamber 7 , and an output shaft of the motor 21 is fixedly connected to a reciprocating screw rod 22 .

[0031] The motor 21 drives the reciprocating screw 22 to rotate, providing power for the reciprocating movement of the piston plate 23 .

[0032] Among them, mounting plates 24 are fixedly installed on the left and right sides of the inflation chamber 7, the mounting plates 24 and the protective plates 5 fit each other, and the internal threads of the mounting plates 24 are sleeved with bolts 25, one end of the bolts 25 passes through the interior of the protective plate 5 and is threadedly sleeved with the protective plate 5.

[0033] After the user completes the inflation, the user can rotate the two sets of bolts 25 to make the bolts 25 leave the interior of the protective plate 5 with which the bolts 25 are threadedly sleeved, and further the inflation chamber 7 is completely dismantled.

[0034] By setting up the inflation chamber 7, the user can control the operation of the motor 21 to realize the inflation of the airbag 6, and after the inflation is completed, the inflation chamber 7 can be removed from the surface of the protective plate 5 by rotating the bolt 25.

[0037] Among them, a plug 16 is movably installed inside the intake pipe 14, and a limiting groove 18 is provided on both sides of the plug 16. The plug 16 is movably connected to the fixing frame 17 through the limiting groove 18, and the plug 16 and the fixing frame 17 are elastically connected through a spring 19.

[0038] When the piston plate 23 moves backward, the plug 16 will be reset by the elastic potential energy of the spring 19, and further, the plug 16 will block the baffle 15 to prevent gas from escaping.

[0039] Working principle and usage process: When performing sports exercises that require frequent use of the knee joint, the user tears the Velcro 3 off the patch 4, ties the upper strap 1 to the thigh, ties the lower strap 1 to the calf, and adjusts them to a comfortable position according to the user, then fits the Velcro 3 and the patch 4 together to complete the wearing. At this time, the user can start the motor 21, and the fixed frame 12 drives the reciprocating screw 22 to rotate. Further, the piston plate 23 reciprocates back and forth along the reciprocating screw 22. When the piston plate 23 moves forward, the plug 10 does not move, and the plug 2 16 is pulled by the air pressure inside the inflation chamber 7, causing the spring 2 19 to be compressed. At this time, the outside air will enter the interior of the inflation chamber 7 from the air inlet pipe 14. When the piston plate 23 moves backward, the plug 2 16 will pass through the spring The elastic potential energy of spring 2 19 is reset, and further, plug 2 16 blocks baffle 2 15 to prevent gas from escaping. At this time, piston plate 23 pushes the air stored in the inflation chamber 7 into the inflation port 9, and plug 10 compresses spring 13 downward, and further air is filled into the interior of the airbag 6 from the inflation port 9. The above working process is repeated, and the airbag 6 will gradually expand, so that the strap 1 and the user's leg are completely fitted, and a certain pressure is applied. Then the user stops the motor 21 and starts exercising. At this time, the complete fit of the strap 1 and the partial pressure applied can improve the stability of the joint. After the user completes the inflation, the user can rotate the two sets of bolts 25 to make the bolts 25 leave the interior of the protective plate 5 with which it is threaded. Further, the inflation chamber 7 is removed.
