Description

Technical Field

[0001] The present invention belongs to the technical field of fitness equipment, and particularly relates to a fitness toy with a driving device. Background Art

[0002] With the development of social economy and the improvement of people's living standards, current toys increasingly emphasize fitness functions. People hope that while being interesting, they can also exercise the body and promote physical and mental health. Therefore, toys with fitness functions are gradually welcomed by the market.

[0003] The speed arm is a fitness toy with upper limb strength training, sports rehabilitation, and interestingness. The speed arm utilizes the elastic action of a spring to provide continuous resistance for arm movement. When a user holds the handle and performs actions such as pushing, pulling, and bending, the spring will exert resistance on the arm muscles, thereby achieving the exercise effect. This resistance training helps to increase muscle strength, endurance, and explosive power. However, arm training is a training process that requires coherence, persistence, and gradual progress. Existing speed arms are difficult to automatically adjust the training difficulty during the training process. The trainer needs to interrupt the training and adjust the resistance of the spring, such as by adjusting a knob, to adjust the training difficulty of the device, which makes the training of the device on the arm less satisfactory. Summary of the Invention

[0004] The purpose of the present invention is to propose a fitness toy with a driving device to solve the problem that existing fitness toys are difficult to automatically adjust the training difficulty during the training process, resulting in less satisfactory training of the device on the arm.

[0006] A fitness toy with a driving device includes a connecting column, two outer ring bodies fixedly connected to the outer surface of the connecting column, and an inner ring body rotatably connected to the outer surfaces of the two outer ring bodies. Two piston rods are slidably connected to the inner wall of a piston groove opened inside the connecting column. A compression spring is arranged inside the piston groove. Both piston rods are slidably connected to a group of arc-shaped abutting blocks fixedly connected to the inner wall of the outer ring body. The arc-shaped cylinders fixedly connected to the inner walls of the two outer ring bodies are each connected to the inside of the piston groove through a first one-way valve. A second one-way valve fixedly connected to the outer surface of the connecting column is connected to the inside of the piston groove. A pair of piston plates are slidably connected to the inner walls of both arc-shaped cylinders. A group of friction blocks are fixedly connected to the outer surface of each piston plate through a straight rod.

[0007] As a further description of the above technical solution:

[0008] Both ends of the compression spring are fixedly connected to the outer surface of a piston rod. Both ends of the telescopic spring arranged inside the arc-shaped cylinder are fixedly connected to the outer surface of a piston plate. One end of the straight rod is fixedly connected to the outer surface of the piston plate, and the other end of the straight rod is fixedly connected to the outer surface of the friction block.

[0009] As a further description of the above technical solution:

[0010] The air inlet end of the first one-way valve and the air outlet end of the second one-way valve are both communicated with the inside of the piston groove, and the air outlet end of the first one-way valve is communicated with the inside of the arc-shaped cylinder. The air inlet end of the second one-way valve is communicated with the outside. A grip rod is fixedly connected to the outer surface of each of the two inner ring bodies.

[0011] As a further description of the above technical solution:

[0012] The connection part between the first one-way valve and the arc-shaped cylinder is located between the two piston plates. The straight rod and the friction block penetrate through the arc-shaped cylinder and the outer ring body, and the penetration parts of the straight rod and the friction block with the arc-shaped cylinder and the outer ring body are both slidably connected. The friction block is in contact with the inner wall of the inner ring body.

[0013] As a further description of the above technical solution:

[0014] A group of limiting rings are fixedly connected to the inner wall of the piston groove. The connection part between the first one-way valve and the inside of the piston groove is located in the middle of the two limiting rings. The piston rod penetrates through the connecting column and extends to the inside of the outer ring body, and the penetration part of the piston rod and the connecting column is slidably connected.

[0015] As a further description of the above technical solution:

[0016] A cavity is formed inside the connecting column. Both of the two arc-shaped cylinders are communicated with the inside of the cavity. A threaded rubber plug threadedly connected to the outer surface of the connecting column extends into the inside of the cavity.

[0017] As a further description of the above technical solution:

[0018] A rubber airbag is fixedly connected to the outer surface of the connecting column. A group of massage blocks are inlaid on the outer surface of the rubber airbag, and a pair of oscillation motors adapted to the massage blocks are fixedly connected to the inner wall of the rubber airbag.

During this process, the piston rod intermittently contacts the outer surface of the arc-shaped abutment block. Under the reaction force, the piston rod reciprocates left and right inside the piston groove, enabling external air to flow into the inside of the arc-shaped cylinder. The air pressure inside the arc-shaped cylinder continuously increases, and the piston plate drives the straight rod and the friction block to move outwards, increasing the force of contact between the friction block and the inner wall of the inner ring body. Thus, resistance is provided for the rotation of the inner ring body on the outer surface of the outer ring body, and the resistance increases continuously during the training process. The device can automatically increase the training difficulty of the device during the training process, thereby enhancing the training effect of the device. Description of the Drawings

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-7, the present invention provides a technical solution: a fitness toy with a driving device, including a connecting column 1, two outer ring bodies 2 fixedly connected to the outer surface of the connecting column 1, and an inner ring body 3 rotatably connected to the outer surfaces of the two outer ring bodies 2. A cavity 16 is formed inside the connecting column 1, and both arc-shaped cylinders 7 communicate with the inside of the cavity 16. The connection between the cavity 16 and the arc-shaped cylinders 7 is located between the two piston plates 9, ensuring that the air accumulated between the two piston plates 9 inside the arc-shaped cylinders 7 can flow with the inside of the cavity 16. A threaded rubber plug 17 threadedly connected to the outer surface of the connecting column 1 extends into the inside of the cavity 16. The threaded rubber plug 17 is usually composed of a rubber main body and a threaded component. The rubber main body has good elasticity and sealing performance, can adapt to certain deformations and pressure changes, and ensures the sealing effect. The threaded component is used to connect with the corresponding threaded hole or threaded pipe joint to achieve quick and reliable connection. By rotating the threaded rubber plug 17, the threaded rubber plug 17 can be disengaged from the outer surface of the connecting column 1, and then the air inside the arc-shaped cylinder 7 can flow to the outside through the cavity 16, reducing the pressure on the piston plate 9 inside the arc-shaped cylinder 7 to reset, and reducing the force of the friction block 11 contacting the inner wall of the inner ring body 3. A lifting rod 22 is arranged directly above the connecting column 1. The two ends of the lifting rod 22 are respectively fixedly connected to the outer surface of an outer ring body 2. A rubber layer 23 is fixedly connected to the outer surface of the lifting rod 22. The setting of the rubber layer 23 increases the friction force on the outer surface of the lifting rod 22, facilitating the trainer's grasping. The device can be driven by holding the lifting rod 22 to perform arm weight-bearing exercises to further train the arm strength. For example, weight-bearing front push. The weight-bearing front push action mainly exercises the biceps brachii, triceps brachii and shoulder muscles, can significantly enhance the strength of these muscles. By repeating the weight-bearing front push action, the muscle endurance can be improved, enabling the muscles to work continuously for a longer time without fatigue. Persisting in weight-bearing front push training for a long time helps to shape the muscle lines of the arms and shoulders, making the figure more beautiful. A rubber airbag 19 is fixedly connected to the outer surface of the connecting column 1. A group of massage blocks 20 are inlaid on the outer surface of the rubber airbag 19, and a pair of oscillating motors 21 adapted to the massage blocks 20 are fixedly connected to the inner wall of the rubber airbag 19. The working principle of the oscillating motor 21 is mainly based on the rotation of an unbalanced rotor. When the motor is started, the eccentric block on the rotor rotates with the rotor. Due to the uneven mass distribution of the eccentric block, a centrifugal force will be generated during rotation. This centrifugal force is transmitted to the vibrating mechanism through the support structure of the motor, causing it to vibrate. A mobile power source electrically connected to the oscillating motor 21 is arranged on the outer surface of the connecting column 1. The rubber airbag 19 and the massage blocks 20 can be brought into contact with the trainer's arm. With the cooperation of the oscillating motor 21, the trainer's arm after training can be massaged and relaxed, increasing the practicality of the device.

[0033] The outer surfaces of both inner rings 3 are fixedly connected with holding rods 15. By holding the holding rods 15, the inner rings 3 are driven to rotate on the outer surface of the outer ring 2. Two piston rods 5 are slidably connected to the inner wall of the piston groove 4 formed inside the connecting column 1. The piston rods 5 penetrate through the connecting column 1 and extend into the interior of the outer ring 2, and the penetration part of the piston rods 5 and the connecting column 1 is slidably connected. A compression spring 12 is arranged inside the piston groove 4, and both ends of the compression spring 12 are fixedly connected to the outer surface of one piston rod 5. Figure 1 and Figure 3 the compression springs 12 in are in a natural state. Both piston rods 5 are slidably connected to a set of arc-shaped abutting blocks 6 fixedly connected to the inner wall of the outer ring 2. The piston rods 5 intermittently contact a set of arc-shaped abutting blocks 6 inside the inner ring 3. The arc-shaped abutting blocks 6 do not contact the inner wall of the outer ring 2 and the outer surface of the arc-shaped cylinder 7, preventing friction between the arc-shaped abutting blocks 6 and the inner wall of the outer ring 2 and the outer surface of the arc-shaped cylinder 7 when the inner ring 3 drives the arc-shaped abutting blocks 6 to rotate. The arc-shaped cylinders 7 fixedly connected to the inner walls of both outer rings 2 are all connected to the interior of the piston groove 4 through first one-way valves 8. The connection part of the first one-way valve 8 and the arc-shaped cylinder 7 is located between two piston plates 9. The second one-way valve 13 fixedly connected to the outer surface of the connecting column 1 is connected to the interior of the piston groove 4. A set of limiting rings 18 are fixedly connected to the inner wall of the piston groove 4. The connection part of the first one-way valve 8 and the interior of the piston groove 4 is located between two limiting rings 18. The limiting rings 18 play a role in limiting the movement of the piston rods 5 inside the piston groove 4. The working principle of the one-way valve mainly depends on the pressure difference of the fluid and the self-weight or spring force of the valve core. When the fluid flows in from the inlet end, the fluid pressure pushes the valve core open to allow the fluid to pass through; while when the fluid tries to flow back from the outlet end, the valve core closes under the action of the fluid pressure and the spring force to prevent the fluid from flowing back.

[0034] The trainer holds the grip rod 15 and performs exercises such as wrist-twisting and flat-pushing, internal and external wrist flipping, and rapid forward and backward rotation, causing the inner ring body 3 to rotate on the outer surface of the outer ring body 2. This device is a fitness equipment for exercising the arm and shoulder muscles, and can achieve different exercise effects through various movements. Wrist-twisting and flat-pushing means keeping the arm straight, centering on the wrist, pushing the speed arm device to one side flatly while making a slight twisting movement of the wrist, and then pulling the speed arm device back to the starting position with the wrist twisting in the opposite direction. Repeat this action, and it can be alternated left and right. This action mainly exercises the muscles of the wrist and forearm, especially the flexor carpi and extensor carpi, and also helps to enhance the stability of the shoulder; Internal and external wrist flipping means keeping the arm still, centering on the wrist, flipping the speed arm device inward and then flipping it outward back to the starting position. Repeat this action, and the speed can be gradually increased. This action mainly exercises the flexibility and strength of the wrist, especially the pronator teres and supinator of the wrist. Through the practice of internal and external wrist flipping, the stability and endurance of the wrist can be enhanced; Rapid forward and backward rotation means centering on the wrist and forearm, quickly rotating the speed arm device forward and then backward back to the starting position. Repeat this action as fast as possible to simulate the actions of punching or quickly swinging the arm. This action mainly exercises the rapid explosive power of the wrist and forearm, as well as the flexibility and strength of the shoulder. Through the practice of rapid forward and backward rotation, the punching speed and strength of the arm can be improved, which is very helpful for the training of sports such as boxing and fighting; During the process, the piston rod 5 intermittently contacts the outer surface of the arc-shaped abutment 6, and the piston rod 5 reciprocates left and right inside the piston groove 4 under the reaction force, causing the external air to flow into the inside of the arc-shaped cylinder 7 through the second one-way valve 13, the piston groove 4 and the first one-way valve 8. The air pressure inside the arc-shaped cylinder 7 continuously increases, and the piston plate 9 drives the straight rod 10 and the friction block 11 to move outward, increasing the force of the friction block 11 in contact with the inner wall of the inner ring body 3, thereby providing resistance for the rotation of the inner ring body 3 on the outer surface of the outer ring body 2, and the resistance increases continuously during the training process. The device can automatically increase the training difficulty of the device during the training process, thereby increasing the training effect of the device.

[0035] The intake end of the first one-way valve 8 and the outlet end of the second one-way valve 13 are both connected to the inside of the piston groove 4, and the outlet end of the first one-way valve 8 is connected to the inside of the arc-shaped cylinder 7. The intake end of the second one-way valve 13 is connected to the outside. The settings of the first one-way valve 8 and the second one-way valve 13 ensure the flow direction of the air inside the piston groove 4, that is, the external air flows into the inside of the arc-shaped cylinder 7 through the second one-way valve 13, the piston groove 4 and the first one-way valve 8. A pair of piston plates 9 are slidably connected to the inner walls of the two arc-shaped cylinders 7, and both ends of the telescopic spring 14 arranged inside the arc-shaped cylinder 7 are fixedly connected to the outer surface of a piston plate 9. The telescopic spring 14 plays a role in resetting and buffering the piston plate 9. Figure 7The telescopic spring 14 therein is in a natural state. A set of friction blocks 11 are fixedly connected to the outer surface of each piston plate 9 through a straight rod 10. One end of the straight rod 10 is fixedly connected to the outer surface of the piston plate 9, and the other end of the straight rod 10 is fixedly connected to the outer surface of the friction block 11. The straight rod 10 and the friction block 11 penetrate through the arc-shaped cylinder 7 and the outer ring body 2, and the penetration parts of the straight rod 10 and the friction block 11 with the arc-shaped cylinder 7 and the outer ring body 2 are slidably connected to prevent friction at the penetration parts of the straight rod 10 and the friction block 11 with the arc-shaped cylinder 7 and the outer ring body 2. The friction block 11 is in contact with the inner wall of the inner ring body 3, and the contact between the friction block 11 and the inner ring body 3 provides resistance for the rotation of the inner ring body 3 on the outer surface of the outer ring body 2.

[0036] Working principle: During use, the trainer holds the grip rod 15 and makes movements such as wrist-twisting and flat-pushing, internal and external wrist-flipping, and rapid forward and backward rotation, causing the inner ring body 3 to rotate on the outer surface of the outer ring body 2. During this process, the piston rod 5 intermittently contacts the outer surface of the arc-shaped abutment 6. Under the reaction force, the piston rod 5 reciprocates left and right inside the piston groove 4, allowing external air to flow into the arc-shaped cylinder 7. The air pressure inside the arc-shaped cylinder 7 continuously increases, and the piston plate 9 drives the straight rod 10 and the friction block 11 to move outwards, increasing the force of contact between the friction block 11 and the inner wall of the inner ring body 3, thereby providing resistance for the rotation of the inner ring body 3 on the outer surface of the outer ring body 2, and the resistance increases continuously during the training process. The device can automatically increase the training difficulty of the device during the training process, thereby enhancing the training effect of the device.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
