Description

Technical Field

[0001] The present invention relates to the technical field of leg recovery devices, and specifically to a leg strength recovery device for sports ability development. Background Art

[0002] In the current context of the upsurge of national fitness and the booming development of competitive sports, people pay more and more attention to the development of their own sports ability. Whether it is professional athletes aiming to improve their competitive level or ordinary fitness enthusiasts pursuing better sports performance, they all need to rely on effective training and recovery means. As an important sports support part of the human body, the improvement and recovery of the strength and function of the legs are crucial;

[0003] At present, there are various leg strength training and recovery devices on the market. Traditional leg strength training devices, such as leg trainers, mainly focus on exercising leg muscle strength through methods such as weight-bearing and flexion-extension to enhance leg movement ability, but lack the function of relaxing and massaging leg muscles. After long-term high-intensity leg training, muscles are prone to fatigue, soreness, and even injury. Simple training devices cannot relieve these problems in time, which is not conducive to subsequent training and physical recovery. Existing leg massage devices, although they can relax and massage leg muscles to promote blood circulation, have limited effects on sports ability development and cannot meet the dual needs of people to relax and recover while exercising leg strength;

[0004] In view of the limitations of the functions of traditional devices, it is imperative to develop a leg strength recovery device that can not only effectively exercise leg strength but also massage and relax the legs. This innovative device will fill the market gap and provide more comprehensive and efficient services for athletes, fitness enthusiasts, and people with leg rehabilitation needs, helping them improve their sports ability and promote the recovery of leg function.

[0005] After retrieval, it is found that the prior art publication number is CN216295134U, which discloses a leg strength recovery device for sports ability development, including a bottom plate. Support legs are provided at the bottom of the bottom plate. One side of the top of the bottom plate is welded with a support rod. A sliding rod is arranged in the through groove of the support rod. A positioning hole is opened inside the sliding rod, and a pin is arranged inside the positioning hole. A seat cushion is arranged at the top of the sliding rod. In this utility model, when the fixed pin disengages from the middle groove of the telescopic rod, the patient's two legs can directly move downward, and the leg strength drives the lifting rod to move downward, so that the lifting rod squeezes the return spring, facilitating the recovery of the patient's leg movement ability. Then, when the fixed pin is connected to the groove in the middle of the telescopic rod, the strength of a single leg can be recovered in sequence, so that the operation mode of the leg strength recovery device can be changed, improving the recovery effect of the patient's legs and accelerating the recovery speed of the patient's leg movement ability.

[0006] Therefore, based on the above retrieval and combined with the existing ones, when using the above solution, its main function is to help patients recover their leg movement ability. After the fixing pin is connected to the groove in the telescopic rod, it can perform strength recovery training on one leg at a time. However, this solution has obvious limitations. On the one hand, it does not have the function of massaging the legs and cannot help patients relax the leg muscles and promote blood circulation after training. On the other hand, it cannot adjust the strength of each leg exertion and is difficult to make personalized adjustments according to the actual situation and rehabilitation stage of the patients, which to a certain extent limits its adaptability to the rehabilitation needs of different patients. For this reason, we propose a leg strength recovery device for exercise ability development. Summary of the Invention

[0007] The purpose of the present invention is to provide a leg strength recovery device for exercise ability development to solve the problems raised in the above background technology.

[0008] To achieve the above purpose, the present invention provides the following technical solutions:

[0009] A leg strength recovery device for exercise ability development includes a device housing. The bottom of the device housing is fixedly connected with an installation base. The right end of the device housing is also fixedly connected with two installation rectangular boxes. Each installation rectangular box is internally slidably connected with a foot pedal, and a transmission mechanism is fixedly connected between the two foot pedals.

[0010] Users can place their feet on the upper ends of the two foot pedals and then exercise by stepping on the two foot pedals back and forth through the transmission mechanism. A power storage mechanism is fixedly connected to the upper end of each foot pedal, and a massage mechanism capable of massaging the user's legs is also fixedly connected to the upper end of each foot pedal.

[0011] As a further improvement of this solution, the transmission mechanism includes a connection main pipe, which is fixedly connected to the inner wall of the device housing. Both the front and rear ends of the connection main pipe are fixedly connected with a third connection circular pipe. One end of each third connection circular pipe away from the connection main pipe is rotatably connected with a rotating circular block.

[0012] As a further improvement of this solution, one end of each rotating circular block away from the third connection circular pipe is rotatably connected with a first connection circular pipe. A number of liquid permeable ports are provided in both the third connection circular pipe and the rotating circular block. The bottom of each foot pedal is fixedly connected to a sliding block through a first corrugated folding pipe.

[0013] As a further improvement of this solution, each first corrugated folding pipe is filled with liquid water, and a first return spring is also fixedly connected inside the first corrugated folding pipe. Each first corrugated folding pipe is fixedly connected and communicated with the adjacent first connection circular pipe through a first connection pipe.

[0014] As a further aspect of this solution, the energy storage mechanism includes a protective outer tube fixedly connected to the upper end of the pedal. The inner wall of the protective outer tube is also fixedly connected with a mating inner tube. The upper end of the mating inner tube is fixedly connected with a second corrugated folding tube. The bottom of the mating inner tube and the first corrugated folding tube are fixedly connected and communicated through a second connecting circular tube.

[0015] As a further aspect of this solution, a two-way pressure valve is installed inside the second connecting circular tube. The mating inner tube is also filled with liquid water. A piston plate with a reset function is slidably connected to the inner wall of the protective outer tube. The upper end of the mating inner tube is fixedly connected and communicated with a mating telescopic tube. The bottom end of the inner wall of the mating telescopic tube is slidably connected with a plug plate with a reset function.

[0016] As a further aspect of this solution, the bottom of the plug plate and the bottom end of the inner wall of the first corrugated folding tube are fixedly connected by a first pulling rope. The bottom end of the inner wall of the mating telescopic tube is rotatably connected with a recovery wheel with a reset function. A second pulling rope is wound around the outer wall of the recovery wheel. The free end of the second pulling rope is fixedly connected to the bottom end of the inner wall of the mating telescopic tube. The upper end of the recovery wheel is fixedly connected with a second abutting circular plate.

[0017] As a further aspect of this solution, a butting tube is fixedly connected to the bottom of the second abutting circular plate. The upper end of the second abutting circular plate is rotatably connected with a first abutting circular plate. The bottom of the first abutting circular plate and the upper end of the second abutting circular plate are abutted against each other. A plurality of communicating tubes are fixedly connected to the upper end of the first abutting circular plate. The upper end of the first abutting circular plate and the top end of the inner wall of the mating telescopic tube are fixedly connected by a damper.

[0018] As a further aspect of this solution, the energy storage mechanism includes a connecting arm fixedly connected to the upper end of the mating telescopic tube. A plurality of curved tubes are fixedly connected to the end of the connecting arm away from the mating telescopic tube.

[0019] As a further aspect of this solution, a plurality of second elastic telescopic tubes are fixedly connected to the outer wall of each curved tube. Each second elastic telescopic tube is fixedly connected and communicated with the adjacent curved tube. Each curved tube is fixedly connected and communicated with the adjacent communicating tube.

[0020] Beneficial Effects

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. Liquid water in a squeezed state will flow rapidly inside the telescopic tube through the abutting tube into the communicating tube connected thereto. Subsequently, the liquid water enters the connected curved arc tube. Since the first return springs inside each second elastic telescopic tube have different spring constant coefficients, the second elastic telescopic tube with the lowest spring constant coefficient will expand and extend first. When the second elastic telescopic tube expands, it will drive the abutting ball to squeeze and knock on the outer wall of the calf. In this way, not only can the legs be exercised, but also the legs can be beaten and massaged, achieving the dual effects of exercise and relaxation.

[0023] 2. It is also possible to drive the rotating circular block to rotate by rotating the connecting handle. The rotating circular block drives the liquid-permeating port inside to rotate. The gap between the liquid-permeating port inside the rotating circular block and the liquid-permeating ports inside the first connecting circular tube and the third connecting circular tube becomes smaller. In this way, the amount of water flowing between the first connecting circular tube and the third connecting circular tube will become smaller, and the resistance to stepping on the first corrugated folding tube will become larger, thereby realizing the force of each step to achieve the exercise effect.

[0042] Please refer to Figure 6 - Figure 8 As shown, the energy storage mechanism 3 includes a protective outer tube 21 which is fixedly connected to the upper end of the foot pedal 10. The inner wall of the protective outer tube 21 is also fixedly connected with a mating inner tube 22. The upper end of the mating inner tube 22 is fixedly connected with a second corrugated folding tube 27. The bottom of the mating inner tube 22 and the first corrugated folding tube 12 are fixedly connected and communicated through a second connecting round tube 24. And a two-way pressure valve is installed inside the second connecting round tube 24. The inside of the mating inner tube 22 is also filled with liquid water. A piston plate 25 with a reset function is slidably connected to the inner wall of the protective outer tube 21. The piston plate 25 and the bottom end of the inner wall of the mating inner tube 22 are fixedly connected through a second return spring 23. The second return spring 23 can drive the piston plate 25 to quickly reset. A rubber ring is also fixedly connected to the outer wall of the piston plate 25. The rubber ring is also made of rubber material, has good elasticity, and also has good deformation ability. The rubber ring can also enhance the sealing performance between the piston plate 25 and the inner wall of the mating inner tube 22;

[0043] The upper end of the mating inner tube 22 is fixedly connected and communicated with a mating telescopic tube 28. And a plug plate 29 with a reset function is slidably connected to the bottom end of the inner wall of the mating telescopic tube 28. The upper end of the plug plate 29 and the inner wall of the mating telescopic tube 28 are fixedly connected through a first elastic telescopic tube 19. The first elastic telescopic tube 19 can drive the plug plate 29 to quickly reset. The bottom of the plug plate 29 and the bottom end of the inner wall of the first corrugated folding tube 12 are fixedly connected through a first pull rope 26. The outer wall of the first pull rope 26 passes through the inside of the mating inner tube 22, the protective outer tube 21, the installation rectangular box 7 and the first corrugated folding tube 12. The bottom end of the inner wall of the mating telescopic tube 28 is also rotatably connected with a recovery wheel 31 with a reset function through a rotating shaft. And the recovery wheel 31 and the bottom end of the inner wall of the mating telescopic tube 28 are fixedly connected through a reset torsion spring. The reset torsion spring can drive the recovery wheel 31 to quickly reset. And the recovery wheel 31 is located directly above the plug plate 29. A second pull rope 30 is also wound around the outer wall of the recovery wheel 31. And the free end of the second pull rope 30 is fixedly connected to the top end of the inner wall of the mating telescopic tube 28;

[0044] The upper end of the recovery wheel 31 is fixedly connected with a second abutting round plate 35. And the bottom of the second abutting round plate 35 is fixedly connected with an abutting tube 20. The upper end of the second abutting round plate 35 is rotatably connected with a first abutting round plate 34 through a rotating shaft. The bottom of the first abutting round plate 34 and the upper end of the second abutting round plate 35 are in mutual abutment. The upper end of the first abutting round plate 34 is also fixedly connected with a plurality of communicating tubes 32. The plurality of communicating tubes 32 are circumferentially distributed on the upper end of the first abutting round plate 34. The abutting tube 20 is adapted to all the communicating tubes 32. The upper end of the first abutting round plate 34 and the bottom end of the inner wall of the mating telescopic tube 28 are fixedly connected through a damper 39. The damper 39 is located between all the communicating tubes 32;

[0045] Specifically, when liquid water fills into the inner part of the matching telescopic tube 28, the liquid water causes the matching telescopic tube 28 to extend. When the matching telescopic tube 28 extends, the top end of the inner wall of the matching telescopic tube 28 pulls the second pulling rope 30. The second pulling rope 30 drives the recovery wheel 31 to rotate. The recovery wheel 31 drives the butting pipe 20 to rotate. During the rotation of the butting pipe 20, it will be successively connected to the corresponding communicating pipe 32. The liquid water inside the matching telescopic tube 28 will be discharged from the communicating pipe 32, and the damper 39 can slow down the extension speed of the matching telescopic tube 28;

[0046] Please refer to Figure 6 、 Figure 9 As shown in the figure, the energy storage mechanism 3 includes a connecting arm 33. The connecting arm 33 is fixedly connected to the upper end of the matching telescopic tube 28. One end of the connecting arm 33 away from the matching telescopic tube 28 is fixedly connected with a plurality of arc-shaped tubes 37. The plurality of arc-shaped tubes 37 are arranged in an up-and-down array on the outer wall of the connecting arm 33. The arc-shaped tubes 37 are in an "arc shape". The outer wall of each arc-shaped tube 37 is fixedly connected with a plurality of second elastic telescopic tubes 36. Each second elastic telescopic tube 36 is communicated with the inside of the adjacent arc-shaped tube 37. And a third return spring is fixedly connected inside each second elastic telescopic tube 36. The elastic coefficient of the first return spring inside each second elastic telescopic tube 36 is different. One end of the second elastic telescopic tube 36 away from the arc-shaped tube 37 is movably connected with a butting ball 18. And the butting ball 18 is in a "spherical shape". Each arc-shaped tube 37 is fixedly communicated with the adjacent communicating pipe 32.

[0047] The working principle of the present invention is as follows: When in use, the user only needs to place both feet on the upper end of the corresponding foot pedal 10. At this time, when one of the foot pedals 10 is stepped on forcefully, the stepped-on foot pedal 10 squeezes the adjacent first corrugated folding tube 12. The liquid water inside the squeezed first corrugated folding tube 12 enters the first connecting tube 15 and then enters the first connecting circular tube 16. Then, through the liquid permeable opening 14 between the connected first connecting circular tube 16, rotating circular block 17 and the third connecting circular tube 38, it enters the connecting main pipe 11. Then, according to the above working principle, it can be known that the liquid water inside the connecting main pipe 11 enters the inside of another first corrugated folding tube 12. At this time, the corresponding first corrugated folding tube 12 expands and extends;

[0048] When the first corrugated folding tube 12 expands and extends to four-fifths of its own extreme length, the liquid water inside the first corrugated folding tube 12 will generate sufficient pressure to push open the two-way pressure valve inside the corresponding second connecting circular tube 24. The liquid water inside the first corrugated folding tube 12 will flow into the inner fitting tube 22 and push the piston plate 25 to move upward. As the piston plate 25 moves, it will squeeze the liquid water inside the inner fitting tube 22 into the second corrugated folding tube 27, causing the second corrugated folding tube 27 to start expanding and storing energy. Under the continuous squeezing effect, the second corrugated folding tube 27 keeps expanding until it reaches its extreme expansion state, at which point the corresponding first corrugated folding tube 12 starts to expand and extend. When the first corrugated folding tube 12 extends to the limit, since the bottom of the first pull rope 26 is connected to the bottom end of the inner wall of the first corrugated folding tube 12, when the first corrugated folding tube 12 extends to the limit, it will exert a pulling force on the first pull rope 26, and the first pull rope 26 will pull the plug plate 29 downward. At this time, the liquid water inside the second corrugated folding tube 27 will enter the inner fitting telescopic tube 28. During the extension process of the inner fitting telescopic tube 28, due to the limitation of the damper 39, when the inner fitting telescopic tube 28 extends, the top end of the inner wall of the inner fitting telescopic tube 28 will pull the second pull rope 30, and the second pull rope 30 will drive the recovery wheel 31 to rotate. The recovery wheel 31 will drive the butting tube 20 to rotate. When the butting tube 20 abuts and communicates with the adjacent connecting tube 32, the liquid water inside the inner fitting telescopic tube 28 will be discharged from the connecting tube 32, and the damper 39 can slow down the extension speed of the inner fitting telescopic tube 28;

[0049] And because the liquid water inside the inner fitting telescopic tube 28 is always in a squeezed state, when the butting tube 20 rotates, it will communicate with the adjacent connecting tube 32. And when communicating, the communication time is limited. The squeezed liquid water will quickly enter the connected connecting tube 32 inside the inner fitting telescopic tube 28 through the butting tube 20, and then enter the connected arc tube 37 from the connecting tube 32. The elastic coefficient of the first return spring inside each second elastic telescopic tube 36 is different, so the second elastic telescopic tube 36 with the lowest elastic coefficient expands and extends first each time. When the second elastic telescopic tube 36 expands, it can drive the butting ball 18 to squeeze and knock on the outer wall of the calf, and the connecting arm 33 can also drive all the arc tubes 37 to move, so that the butting ball 18 and the second elastic telescopic tube 36 squeeze and press on the outer wall of the calf;

[0050] When the inflated first corrugated folding tube 12 is squeezed, the liquid water inside the first corrugated folding tube 12 at this time will enter into another first corrugated folding tube 12. And when the foot pedal 10 moves downward, the first pull rope 26 loses tension, and the plug plate 29 will reset. At this time, the second reset spring 23 drives the piston plate 25 to reset. The liquid water inside the inner tube 22 will return to the first corrugated folding tube 12 through the second connecting round tube 24. And the liquid water inside the arc-shaped tube 37, the connecting tube 32 and the telescopic tube 28 will also return to the inner tube 22. When the first corrugated folding tube 12 on the other side expands at this time, according to the above working principle, it can be known that the other leg can be massaged;

[0051] When it is necessary to adjust the stepping pressure, it is necessary to rotate the connecting handle 13. The connecting handle 13 drives the rotating round block 17 to rotate. The rotating round block 17 drives the liquid-permeable port 14 inside it to rotate. The gap between the liquid-permeable port 14 inside the rotating round block 17 and the liquid-permeable ports 14 inside the first connecting round tube 16 and the third connecting round tube 38 becomes smaller. In this way, the amount of water flowing between the first connecting round tube 16 and the third connecting round tube 38 will become smaller, and the resistance to stepping on the first corrugated folding tube 12 will become larger.

[0052] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
