Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pull-up exercise apparatuses, and in particular to a single-bar auxiliary training buoyancy platform. BACKGROUND

[0002] At present, with the improvement of health awareness, pull-ups as a classic full-body strength training method are favored by more and more people. It can not only effectively exercise arm strength and back muscle groups, but also has the effect of improving body coordination and core strength. However, pull-ups are difficult for beginners or those with weak arm strength, and additional assistance is often needed to complete the standard action. Therefore, various pull-up auxiliary training devices have gradually emerged in the market to meet the fitness needs of different groups of people.

[0003] The common pull-up auxiliary devices on the market mainly include elastic band auxiliary devices, hydraulic power assisting devices and mechanical spring power assisting devices. The elastic band auxiliary device uses the stretching characteristics of the elastic band to provide assistance, and its structure is relatively simple and the cost is relatively low. The hydraulic power assisting device provides stable assistance through the work of the hydraulic cylinder and can adapt to larger load changes. The mechanical spring power assisting device relies on the compression and rebound of the spring to generate assistance and can help users complete the pull-up action to some extent. In addition, there are disclosed pull-up exercise apparatuses that displace the support plate up and down through a pulling rope and a pulley and are provided with a locking structure; a forced hook locking device of a pull-up exercise apparatus lifting pedal that ensures safety in use through the cooperation of a touch pressure lever and a buckle column; and a pull-up training device that uses an elastic telescopic rod to provide assistance and reduce noise.

[0004] However, the above-mentioned pull-up auxiliary devices have obvious defects. The assistance of the elastic band auxiliary device cannot be adjusted, which cannot meet the needs of users of different weights and training needs, and the elastic band is prone to aging, affecting the service life and safety in use. Although the hydraulic power assisting device can provide stable assistance, its structure is complex, resulting in high cost, which is not conducive to widespread promotion. The mechanical spring power assisting device has a limited assistance adjustment range and is difficult to accurately adapt to the needs of different users, and has poor safety and is prone to accidents. In related technologies, there are also some other pull-up auxiliary devices, such as fixed and non-adjustable devices that are inconvenient to use, or electrically adjustable devices that are prone to electric shock when exposed to rain, which are not suitable for outdoor use, or devices that use a plummer block bearing that is easily damaged by rain, snow, dust and other factors, or devices that use external limiters that have many risks of clamping, shearing and extruding the human body, especially children.

[0005] Therefore, there is a problem of being difficult to reduce costs while considering safety and assistance adjustment flexibility, and there is an urgent need for a single-bar auxiliary training buoyancy platform. SUMMARY

[0006] In order to reduce the cost, safety and flexibility of power adjustment are taken into account, the application provides a single bar auxiliary training buoyancy platform.

[0017] By adopting the above technical scheme, one end of the assisting piece is hinged to the connecting shaft, and the other end is hinged to the movable seat, so that when the driving piece drives the movable seat to move, the change of the position of the movable seat changes the angle and tension of the assisting piece, thereby realizing accurate adjustment of the assisting force. The guide assembly can ensure stable movement of the movable seat, and the setting of the outer cover can effectively brake the guide assembly and the movable seat, avoid dust or other impurities from entering, and ensure the smoothness and reliability of the adjustment process. This structural design not only improves the flexibility and adaptability of the device, but also enhances the overall stability and durability, meeting the needs of different users for the size of the assisting force.

[0019] By adopting the above technical scheme, the two oppositely arranged connecting plates provide stable mounting positions for the plurality of pulleys, and the support beam passes through the plurality of pulleys, so that the pulleys form multi-point support for the support beam, enabling the pulleys to move stably along the support beam. Through the cooperation of the pulleys and the connecting plates, the frictional resistance of the movable seat during movement can be significantly reduced, thereby improving the accuracy and smoothness of the initial force size adjustment of the assisting piece. At the same time, this structural design makes the stress on the support beam more uniform, effectively prolongs the service life of the equipment, and provides users with a more stable and comfortable training experience.

[0020] Optionally, the guide assembly comprises a sliding rail, the sliding rail is arranged in the outer cover, the sliding rail is arranged along the movement direction of the movable seat, and the movable seat is slidably connected with the sliding rail.

[0021] By adopting the above technical scheme, the sliding rail is arranged in the outer cover, and the movable seat is slidably connected with the sliding rail. This structural design can ensure that the movable seat moves smoothly along the predetermined track during adjustment, avoiding the problem of inaccurate adjustment of the initial force of the assisting piece due to shaking or deviation. Moreover, the use of the sliding rail not only improves the stability of the device, but also simplifies the structure of the guide assembly, thereby reducing the manufacturing and maintenance costs.

[0022] Optionally, the guide assembly comprises a guide rod, the guide rod is arranged in the outer cover, the guide rod is arranged along the movement direction of the movable seat, and the movable seat is slidably connected with the guide rod.

[0023] By adopting the above technical scheme, the guide rod can provide stable linear motion guidance for the movable seat, ensure that the movable seat will not deviate or be stuck when adjusting the initial force of the assisting part, and make the assisting part keep uniform distribution during force process, thereby avoiding affecting the training effect due to deviation of the force direction.

[0025] By adopting the above technical scheme, the cooperation of the guide plate and the connecting ring can ensure the stability of the movable seat during movement, and avoid deviation when adjusting the assisting force. The arrangement of the rolling piece further reduces the friction between the movable seat and the guide plate, so that the adjustment process is more smooth. This structural design not only improves the reliability of the equipment, but also prolongs the service life of the parts, thereby ensuring that the assisting force of the assisting mechanism can be accurately adjusted and stably output.

[0026] Optionally, the supporting mechanism comprises a connecting rod and a pedal, one end of the connecting rod is rotatably connected with the frame body, the other end of the connecting rod is connected with the pedal, a locking rod is arranged on the frame body, and the automatic locking assembly comprises two groups, and the two groups of automatic locking assemblies are arranged on the pedal and correspond to the positions of the two feet of the user.

When the pressing rod is pressed down, the locking hook is separated from the locking rod.

[0028] By adopting the above technical scheme, when the user steps on the pedal with both feet, the foot pressure can be transmitted to the rotating piece through the touch pressure rod, so that the rotating piece rotates. The rotation of the rotating piece drives the locking hook to rotate around the hinge point through the connecting rod, so that the locking hook is separated from the lock rod, and the unlocking of the supporting mechanism is realized. When the user leaves the pedal after finishing the training, the restoring force of the first elastic member makes the rotating piece reset, and then drives the locking hook to lock with the lock rod again, ensuring the automatic locking of the supporting mechanism. This design controls the locking state through foot pressure, without manual operation, improving the convenience and safety of use. At the same time, the double-sided locking structure further improves the stability of the device, effectively preventing safety hazards caused by unilateral locking failure.

[0029] Optionally, a hook is arranged on the frame body, and the manual locking assembly comprises a clamping ring and a handle arranged on the clamping ring, the clamping ring being rotationally connected to the connecting rod, and the clamping ring being used to lock with the hook.

[0030] By adopting the above technical scheme, when the user finishes the training, the handle can be pulled backward to lock the clamping ring with the hook, so as to stably fix the supporting mechanism at the lowest position. This design not only prevents equipment damage caused by accidental movement of the supporting mechanism, but also ensures that the equipment is in a safe state before use by the next user.

[0031] Optionally, a protective cover is arranged on the frame body, a rotating rod is arranged on the connecting rod, the rotating rod passes through the protective cover and is rotationally connected to the protective cover and the frame body respectively, a linkage assembly and a brake assembly are arranged in the protective cover respectively, the linkage assembly is connected to the brake assembly and the rotating rod respectively, and when the rotating speed of the rotating rod exceeds a specified value, the linkage assembly can drive the brake assembly to limit the rotating rod.

[0032] By adopting the above technical scheme, when the user is doing pull-up training, if the pedal descends too fast due to improper operation or external force, the brake assembly can quickly respond when the rotating rod rotates at an excessive speed, effectively limiting the rotating rod, so as to avoid impact or accidental injury caused by excessive descent of the pedal due to inertia. This design not only improves the overall stability of the equipment, but also provides additional safety protection for the user, ensuring a more reliable and comfortable training process.

[0033] Optionally, the linkage assembly comprises a first gear, a second gear and a rotating shaft, the first gear is coaxially arranged on the rotating rod, the rotating shaft is rotationally arranged in the protective cover and is arranged in parallel with the rotating rod, and the second gear is coaxially arranged on the rotating shaft and is in mesh with the first gear, and the number of teeth of the first gear is greater than that of the second gear.

[0035] By adopting the above technical scheme, when the rotating rod rotates, the rotating rod can drive the second gear to rotate through the first gear, the second gear can drive the rotating disc to rotate through the rotating shaft, and because the number of teeth of the first gear is greater than that of the second gear, when the rotating speed of the rotating rod exceeds a specified value, the rotating speed of the rotating disc is accelerated, the arc-shaped baffle slides along the arc-shaped groove under the action of inertia and is separated from the friction block. At this time, the second elastic member pushes the friction block to move along the sliding groove, so that the friction block is inserted into the annular friction groove on the rotating rod and abuts against the inner wall of the annular friction groove, thereby limiting and braking the rotating rod. This design can timely limit the rotating speed of the rotating rod when the user operates improperly or the equipment abnormally, prevent safety hazards caused by the violent swinging of the pedal assembly, and significantly improve the safety of the equipment. In addition, this mechanical braking mechanism does not require additional power support, and has the advantages of rapid response and high reliability.

The supporting mechanism 2 is movably arranged on the frame body 1 and is used for being stepped by a user. The adjusting mechanism 3 and the locking mechanism 5 are arranged on the supporting mechanism 2 respectively. The power assisting mechanism 4 is arranged on the frame body 1 and is connected with the adjusting mechanism 3. The adjusting mechanism 3 is used for adjusting the power assisting size of the power assisting mechanism 4. The locking mechanism 5 is used for locking the supporting mechanism 2. The device realizes the adjustability of the power assisting size through the adjusting mechanism 3, and ensures the safety during the training through the locking mechanism 5.

[0058] The frame body 1 is made of stainless steel and has high strength and corrosion resistance. The supporting mechanism 2 comprises a connecting rod 21 and a pedal 22. The connecting rod 21 is fixedly connected with the pedal 22 at one end. The pedal 22 and the connecting rod 21 are made of non-metallic materials. Anti-skid lines are arranged on the surface of the pedal 22.

[0059] With reference to Figure 2 , the other end of the connecting rod 21 away from the pedal 22 is fixedly connected with a rotating rod 23. The rotating rod 23 is rotatably connected with the frame body 1, so that the connecting rod 21 can drive the pedal 22 to rotate. In other embodiments, the rotating rod 23 can be omitted, and the connecting rod 21 can be directly rotatably connected with the frame body 1.

[0060] With reference to Figure 2 and Figure 3 , the connecting rod 21 is fixedly connected with a supporting beam 24. The supporting beam 24 is used for supporting the adjusting mechanism 3. The adjusting mechanism 3 comprises a driving member 31, a movable seat 32, a guide assembly 33 and an outer cover 34. The outer cover 34 is mounted on the supporting beam 24.

[0061] In this embodiment, the bottom of the outer cover 34 is provided with an opening to avoid the interference of the outer cover 34 with the movement of the movable seat 32. An observation slot 341 is formed in the top of the outer cover 34. A transparent acrylic plate is arranged in the observation slot 341. A weight scale is arranged beside the observation slot 341. A pointer is arranged on the movable seat 32.

In this embodiment, the first elastic member 512 is a tension spring, so that the rotating piece 513 can be pulled by the first elastic member 512 to drive the locking hook 515 to rotate through the connecting rod 514, so that the locking hook 515 hooks the locking rod 11. At this time, the pedal 22 is locked at the lowest position.

[0073] When the user steps on the pedal 22, the foot pressure can be transmitted to the rotating piece 513 through the pressing rod 511, so that the rotating piece 513 rotates, and the rotating piece 513 drives the locking hook 515 to rotate through the connecting rod 514, so that the locking hook 515 is separated from the locking rod 11, thereby realizing the unlocking operation. At this time, the first elastic member 512 is in a compressed state.

[0074] With reference to Figure 5 , the manual locking assembly 52 comprises a clamping ring 521 and a handle 522 fixedly connected to the clamping ring 521, and the clamping ring 521 is rotatably connected to the connecting rod 21.

Then, the hand wheel 311 is rotated, the hand wheel 311 drives the movable seat 32 to move through the screw rod 312, and the movable seat 32 drives the power assisting piece 43 to move, so as to adjust the initial force of the power assisting piece 43 to be appropriate.

[0079] Finally, the user holds the gripping rod 62 with both hands, and starts to perform the pull-up movement, along with the force applied by the user, the body of the user is gradually lifted, at the same time, the pedal 22 is lifted by the power assisting piece 43 through the connecting rod 21, so as to assist the user to complete the pull-up action.

[0080] In the embodiment, the surface of the single bar auxiliary training buoyancy platform is subjected to the green environmental protection process of shot blasting and cleaning, and the surface is sprayed with outdoor environmental protection non-toxic polyester powder and electrostatic powder, so as to meet the outdoor corrosion resistance requirement of the product, thereby reducing the possibility of damage of the device caused by rain, snow and other factors to a certain extent. The single bar auxiliary training buoyancy platform in the application does not use the electric adjustment mode, so as to avoid the risk of electric shock, and is more suitable for outdoor environment.

[0089] Embodiment 4

[0090] With reference to Figure 2 and Figure 8 The difference between the embodiment and the embodiment 1 is that the guide assembly 33 comprises a guide plate 335, a connecting ring 336 and a rolling part 337.

[0091] The guide plate 335 is installed in the outer cover 34, and the guide plate 335 is arranged in a spaced manner with the inner surface of the side of the outer cover 34 away from the support beam 24.

[0092] The cooperation of the guide plate 335 and the connecting ring 336 can ensure the stability of the movable seat 32 during movement, avoiding deviation during adjustment of the assist size. The arrangement of the rolling member 337 further reduces the friction between the movable seat 32 and the guide plate 335, making the adjustment process smoother. This structural design not only improves the reliability of the equipment, but also prolongs the service life of the components, thereby ensuring that the assist size of the assist mechanism 4 can be accurately adjusted and stably output.

[0093] Embodiment 5

[0094] With reference to Figure 9 and Figure 10 , the difference between this embodiment and embodiment 1 is that the bracket 1 is provided with a protective cover 12, and the linkage assembly 13 and the brake assembly 14 are arranged in the protective cover 12, respectively.

[0095] The rotating rod 23 penetrates through the protective cover 12 and is rotationally connected with the protective cover 12 and the bracket 1, respectively. The rotating rod 23 is provided with an annular friction groove 231 around the axis direction thereof. The linkage assembly 13 includes a first gear 131, a second gear 132, and a rotating shaft 133. The first gear 131 is coaxially arranged on the rotating rod 23, the rotating shaft 133 is rotationally connected in the protective cover 12 and is arranged in parallel with the rotating rod 23, and the second gear 132 is coaxially arranged on the rotating shaft 133 and is in mesh with the first gear 131.

[0096] In this embodiment, the number of teeth of the first gear 131 is greater than the number of teeth of the second gear 132, so that when the rotating rod 23 drives the first gear 131 to rotate by a small angle, the second gear 132 will rotate at a greater angular velocity. It should be noted that the specific number of teeth of the first gear 131 and the second gear 132 can be designed according to actual needs, and therefore will not be described in detail in this embodiment.

[0097] With reference to Figure 10 and Figure 11 , the brake assembly 14 includes a rotating disc 141, an arc-shaped baffle 142, a friction block 143, and a second elastic member 144. The rotating disc 141 is coaxially arranged on the rotating shaft 133, the rotating disc 141 is provided with an arc-shaped groove 1411 around the axis direction thereof, and the rotating disc 141 is provided with a sliding groove 1412 in the direction perpendicular to the axis direction thereof, and the sliding groove 1412 is in communication with the arc-shaped groove 1411.

[0098] The arc-shaped baffle 142 is slidingly arranged in the arc-shaped groove 1411, the friction block 143 is slidingly arranged in the sliding groove 1412, and the second elastic member 144 is arranged in the sliding groove 1412 and connected with the friction block 143. In this embodiment, the second elastic member 144 is a spring, so as to facilitate driving the friction block 143 to slide out of the sliding groove 1412 by the second elastic member 144.

[0099] ​The rotating disc 141 is provided with a limiting block 1413, which is in contact with the friction block 143 and is used to limit the friction block 143 in the sliding groove 1412 to avoid the friction block 143 from being separated from the sliding groove 1412.

[0100] In the initial state, the second elastic member 144 pushes the friction block 143 to be in contact with the arc-shaped baffle 142. In this state, the arc-shaped baffle 142 is not easy to be separated from the friction block 143.

[0101] When the rotating rod 23 rotates normally, the rotating rod 23 drives the second gear 132 to rotate through the first gear 131, the second gear 132 drives the rotating disc 141 to rotate through the rotating shaft 133, and the rotating disc 141 drives the second elastic member 144, the friction block 143 and the arc-shaped baffle 142 to rotate. At this time, the friction block 143 keeps in contact with the arc-shaped baffle 142.

[0102] When the rotating speed of the rotating rod 23 exceeds the specified value, the rotating speed of the rotating disc 141 also exceeds the specified value, the arc-shaped baffle 142 slides in the arc-shaped groove 1411 under the action of inertia and is separated from the friction block 143. At this time, the second elastic member 144 pushes the friction block 143 to move along the sliding groove 1412, so that the friction block 143 is inserted into the annular friction groove 231 on the rotating rod 23 and is attached to the inner wall of the annular friction groove 231, thereby limiting and braking the rotating rod 23.

[0103] When the user operates improperly, the equipment is abnormal or damaged, the pedal 22 will quickly fall down or swing violently, thereby easily causing the generation of safety hazards. At this time, through the cooperation of the linkage assembly 13 and the braking assembly 14, the rotating speed of the rotating rod 23 can be limited in time, the safety hazards are reduced, and the safety of the equipment use is significantly improved. In addition, this mechanical protection mechanism does not need additional power support, and has the advantages of rapid response and high reliability.

[0104] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the braking range of the present application.
