TECHNICAL FIELD

[0001] The present application relates to the technical field of sports training equipment, and particularly relates to a multifunctional sports training equipment resistance adjusting device. BACKGROUND

[0002] At present, a Chinese utility model patent with the authorization announcement number CN218106655U discloses a multifunctional sports training equipment. The sports training equipment of the utility model patent has multiple functions and aims to meet the diversified training needs of users. Specifically, the equipment is provided with a massage cylinder, which is driven by a transmission handle to reciprocatingly rotate the massage cylinder, and the protrusions on the outer end of the massage cylinder massage the back of the user, so as to relax the muscles and promote blood circulation. In addition, the equipment is provided with a U-shaped frame, which provides stretching training functions for the left and right hands. Stretching rods are arranged at the two ends of the U-shaped frame, and the user can perform simple stretching actions by pulling the stretching rods. Meanwhile, a positioning block is arranged at the middle of the U-shaped frame, and the positioning block can drive the U-shaped frame to slide at the second sliding rod. When the U-shaped frame slides, the counterweight block in the main body slides, so as to increase the difficulty and effect of training, and the back, arm strength and hand coordination of the user can be trained.

[0003] However, in actual application, the counterweight block lacks a structure for adjusting the resistance during movement. Since the physical conditions, strength and training needs of different users are different, a fixed resistance setting cannot meet the needs of all users. This leads to different training effects for different users, and some users may not achieve ideal training effects due to excessive or insufficient resistance.

[0004] Therefore, the present application provides a multifunctional sports training equipment resistance adjusting device to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a multifunctional sports training equipment resistance adjusting device, which aims to solve the problem that the existing counterweight block lacks a structure for adjusting the resistance during movement. Since the physical conditions, strength and training needs of different users are different, a fixed resistance setting cannot meet the needs of all users. This leads to different training effects for different users, and some users may not achieve ideal training effects due to excessive or insufficient resistance.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a multifunctional sports training equipment resistance adjusting device, comprising a support, a frame arranged at the rear end of the support, a seat arranged at the upper end of the support, a counterweight block slidingly arranged in the seat, a pulley block arranged on the frame, a traction rope arranged on the pulley block and connected with the counterweight block, and a pull ring arranged at the end of the traction rope.

[0007] In order to facilitate the adjustment of the resistance of the weight block: the inside of the seat is provided with an adjusting structure for adjusting the resistance of the weight block, which comprises a drive screw threadedly connected to the rear end of the seat, a rotating plate provided in the inside of the seat and rotationally connected to the drive screw, and a first spring provided between the rotating plate and the weight block. By adding the adjusting structure, flexible adjustment of the resistance of the weight block is achieved, meeting the training needs of different users. The adjusting structure is simple and practical, and easy to operate. Users only need to rotate the drive screw to adjust the resistance. By adjusting the elasticity of the first spring, the resistance of the weight block can be accurately controlled, improving the training effect. When the resistance of the weight block needs to be adjusted, the user first rotates the handle of the drive screw. Since the drive screw is threadedly connected to the rotating plate, rotating the drive screw will move the rotating plate inside the seat. When the rotating plate moves, it will compress or release the first spring, thereby changing its elastic force on the weight block. When the first spring is compressed, its elastic force on the weight block increases, thereby increasing the resistance of the weight block. Conversely, when the first spring is released, its elastic force on the weight block decreases, thereby reducing the resistance of the weight block. Therefore, by adjusting the elasticity of the first spring, flexible adjustment of the resistance of the weight block can be achieved.

[0008] Preferably, in order to facilitate the rotation of the drive screw: the rear end of the drive screw is fixedly connected with a key plate for assisting the rotation of the drive screw. By adding the key plate, the convenience and stability of the rotation of the drive screw are improved, making the resistance adjustment process more comfortable and accurate. The design of the key plate takes into account the ergonomic principle, providing a comfortable gripping experience and reducing hand fatigue during long-term use.

[0009] Preferably, in order to prevent violent impact between the weight block and the seat: the inside of the seat is provided with a second spring corresponding to the front end of the weight block. By adding the second spring, the impact force between the weight block and the seat is effectively reduced, avoiding loud impact sound and equipment damage, improving the durability and safety of the equipment. The buffering effect of the second spring makes the training process more stable and comfortable, reducing the discomfort and psychological pressure of the user.

[0010] Preferably, in order to improve the comfort of the user: the upper end of the seat is provided with a sponge pad. By setting the sponge pad, the comfort of the user is significantly improved, reducing the discomfort of the hips and waist caused by long-term training, improving the training efficiency and continuity. The high-density and high-elasticity material of the sponge pad makes the seat have better support and resilience, which can adapt to different user body types and sitting habits.

[0011] Preferably, in order to massage the back of the user during the pull training: a plurality of massage rollers for back massage are rotatably arranged on the backrest of the seat. By arranging the massage rollers, additional back massage function is provided for the user during the pull training, which helps to relax the back muscles and relieve fatigue and tension caused by training. The rotation arrangement of the massage rollers makes the massage process more natural and smooth, increasing the interest and diversity of training.

[0012] Preferably, a positioning rod for leg exercise is arranged on the frame. By arranging the positioning rod, additional leg exercise function is provided for the user, making the training equipment more comprehensive and diverse. The design of the positioning rod conforms to the ergonomic principle, which can provide stable support and positioning for the user's legs, ensuring the exercise effect.

[0013] Preferably, handles for lifting exercise are symmetrically arranged on the top of the frame. By arranging the handles, additional lifting exercise function is provided for the user, enriching the functionality and diversity of the training equipment. The design of the handles conforms to the ergonomic principle, facilitating the user to hold and operate, improving the comfort and stability during exercise.

[0014] The present application realizes flexible adjustment of the moving resistance of the counterweight by adding the adjusting structure, meeting the training needs of different users. The adjusting structure is simple and practical, easy to operate, and the user only needs to rotate the drive screw to realize the adjustment of the resistance. By adjusting the elasticity of the first spring, the precise control of the moving resistance of the counterweight can be realized, improving the training effect. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0020] ​With reference to the accompanying drawings: clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of the present application.

[0021] The present embodiment provides a multifunctional sports training equipment resistance adjusting device, as shown in the figure, which comprises a support 1, a frame 2 arranged at the rear end of the support 1, a seat 3 arranged at the upper end of the support 1, a counterweight 4 slidingly arranged inside the seat 3, a pulley block 5 arranged on the frame 2, a traction rope 6 arranged on the pulley block 5 and connected with the counterweight 4, and a pull ring 7 arranged at the end of the traction rope 6. Figures 1-3 When using, the user first sits on the seat 3, then holds the pull ring 7 and pulls it down, the pull ring 7 drives the traction rope 6 to move along the pulley block 5, and then pulls the counterweight 4 to move backward along the inside of the seat 3.

[0022] In order to facilitate the adjustment of the resistance of the counterweight 4 when moving, the inside of the seat 3 is provided with an adjusting structure 8 for adjusting the resistance of the counterweight 4 moving, the adjusting structure 8 comprises a driving screw 81 screwed into the rear end of the seat 3, a rotating plate 82 arranged inside the seat 3 and rotatably connected with the driving screw 81, and a first spring 83 arranged between the rotating plate 82 and the counterweight 4. By adding the adjusting structure 8, the resistance of the counterweight 4 moving is flexibly adjusted, meeting the training needs of different users. The adjusting structure 8 is simple and practical, easy to operate, and the user only needs to rotate the driving screw 81 to adjust the resistance. By adjusting the elasticity of the first spring 83, the resistance of the counterweight 4 moving can be accurately controlled, improving the training effect.

[0023] When it is necessary to adjust the resistance of the weight block 4, the user first rotates the handle of the drive screw 81. Since the drive screw 81 is in threaded connection with the rotating plate 82, rotating the drive screw 81 will drive the rotating plate 82 to move inside the seat 3. When the rotating plate 82 moves, it will press or release the first spring 83, thereby changing its elastic force acting on the weight block 4. When the first spring 83 is pressed, its elastic force acting on the weight block 4 increases, thereby increasing the resistance of the weight block 4 to move; on the contrary, when the first spring 83 is released, its elastic force acting on the weight block 4 decreases, thereby reducing the resistance of the weight block 4 to move. Therefore, by adjusting the elastic force of the first spring 83, flexible adjustment of the resistance of the weight block 4 to move can be achieved. In use, the user sets the appropriate resistance value by adjusting the drive screw 81 according to his own training needs and physical conditions. Then sit on the seat 3, hold the pull ring 7 and pull it down, the pull ring 7 drives the traction rope 6 to move along the pulley block 5, and then pulls the weight block 4 to move backward along the inside of the seat 3. During the training process, the movement of the weight block 4 will be affected by the elastic force of the first spring 83, thereby generating corresponding resistance to achieve the training effect.

[0024] Specifically, in order to facilitate the rotation of the drive screw 81, the rear end of the drive screw 81 is fixedly connected with a key plate 811 for assisting the rotation of the drive screw 81. By adding the key plate 811, the convenience and stability of the rotation of the drive screw 81 are improved, making the resistance adjustment process more relaxed and accurate. The key plate 811 is designed considering the principle of ergonomics, providing a comfortable holding experience and reducing hand fatigue during long-term use. The anti-slip material and texture design of the key plate 811 effectively prevent slipping during rotation, improving the safety and reliability of the adjustment process. When it is necessary to adjust the resistance of the weight block 4, the user first holds the key plate 811 and then rotates it with force. Since the key plate 811 is fixedly connected with the rear end of the drive screw 81, rotating the key plate 811 will drive the drive screw 81 to rotate synchronously.

[0025] Specifically, in order to prevent the violent impact between the weight block 4 and the seat 3: the inside of the seat 3 corresponding to the front end of the weight block 4 is provided with a second spring 9. By adding a second spring 9, the impact between the weight block 4 and the seat 3 is effectively reduced, avoiding violent impact and equipment damage, improving the durability and safety of the equipment. The buffering effect of the second spring 9 makes the training process more stable and comfortable, reducing the discomfort and psychological pressure of the user. The selection and arrangement of the second spring 9 can be flexibly adjusted according to actual needs to meet the needs of different training scenarios and users. During training, when the user pulls the weight block 4 back through the pull ring 7 and the traction rope 6, the weight block 4 will move against the elastic force of the first spring 83. When the weight block 4 needs to be released, the first spring 83 will release the elastic force and push the weight block 4 forward. At this time, the second spring 9 will be compressed, absorbing the kinetic energy of the weight block 4, and playing a buffering role. With the continuous movement of the weight block 4, the second spring 9 will gradually restore to its original state, releasing the absorbed kinetic energy, so that the weight block 4 stops smoothly at the front end position inside the seat 3. By adjusting the elastic force and arrangement of the first spring 83 and the second spring 9, the movement resistance and buffering effect of the weight block 4 can be flexibly adjusted to meet the training needs of different users. At the same time, the buffering effect of the second spring 9 also improves the stability and comfort of the training process, making the entire training process more safe and efficient.

[0026] Further, in order to improve the comfort of the user: the upper end of the seat 3 is provided with a sponge pad 31. By setting the sponge pad 31, the comfort of the user is significantly improved, reducing the discomfort of the hips and waist caused by long-term training, and improving the training efficiency and persistence. The high-density and high-elasticity material of the sponge pad 31 makes the seat 3 have better support and resilience, which can adapt to the body shape and sitting habit of different users. The breathable and wear-resistant fabric design of the sponge pad 31 increases the comfort and durability during use, prolonging the service life of the equipment. The working principle of the sponge pad 31 is mainly based on its high-density and high-elasticity material properties. When the user sits on the seat 3, the sponge pad 31 will be moderately compressed and deformed according to the user's body weight and sitting posture, thereby dispersing the pressure on the hips and reducing discomfort. At the same time, the resilience of the sponge pad 31 can ensure that it quickly returns to its original state after the user leaves the seat 3, maintaining the flatness and comfort of the seat 3. In addition, the breathable fabric design of the sponge pad 31 can ensure air circulation during use, reducing the accumulation of sweat and the generation of odor, improving the comfort and hygiene during use.

[0027] Specifically, in order to provide the user with back massage during the pull-up training, a plurality of massage rollers 32 are rotatably arranged on the backrest of the seat 3. The massage rollers 32 provide additional back massage function for the user during the pull-up training, which helps to relax the back muscles and relieve fatigue and tension caused by training. The rotatable arrangement of the massage rollers 32 makes the massage process more natural and smooth, increasing the interest and diversity of training. The design of the massage rollers 32 also takes into account the ergonomic principle, which can ensure that the massage effect is comprehensive and uniform, and will not cause discomfort or harm to the user's back. When the user sits on the seat 3 for pull-up training, the back will naturally fit on the backrest. At this time, the massage rollers 32 will rotate with the movement of the back, providing a gentle massage to the back. At the same time, the rotatable arrangement of the massage rollers 32 makes the massage process more natural and smooth, which will not interfere with the user's training. In addition, the number and layout design of the massage rollers 32 can ensure that the massage effect is comprehensive and uniform. The user can adjust the sitting posture and training intensity according to their own needs and preferences to experience different massage effects.

[0028] Specifically, the frame 2 is provided with a positioning rod 21 for leg exercise. By providing the positioning rod 21, the user is provided with additional leg exercise function, making the training equipment more comprehensive and diverse in function. The design of the positioning rod 21 conforms to the ergonomic principle, which can provide stable support and positioning for the user's legs, ensuring the exercise effect. The height and angle of the positioning rod 21 are adjustable, which can meet the training needs of users of different heights, improve the targeting and effect of training. When using the positioning rod 21 for leg exercise, the user can choose the appropriate posture and action according to the training needs. For example, the legs can be placed on the positioning rod 21 to perform leg stretching, bending and other actions to exercise the flexibility and strength of the leg muscles and joints. The stable support and positioning function of the positioning rod 21 can ensure the stability and safety during exercise, avoiding the risk of injury. At the same time, the user can also adjust the height and angle of the positioning rod 21 to adapt to different training needs and exercise intensity.

[0029] Specifically, the top of the frame 2 is symmetrically provided with handles 22 for lifting exercises. By providing handles 22, users are provided with additional lifting exercise functions, enriching the functionality and diversity of the training equipment. The design of the handles 22 conforms to the ergonomic principle, facilitating the user to hold and operate, improving the comfort and stability during exercise. When using the handles 22 for lifting exercises, the user can hold the handles 22 and perform up-down, left-right or forward-backward lifting movements through the strength of the arms and shoulders. These movements can exercise the muscle strength and endurance of the arms, shoulders, back and chest, etc. The stable support and balance function of the handles 22 can ensure the stability and safety during the exercise process, avoiding the risk of injury. At the same time, the user can also adjust the use of the handles 22 and the intensity of the exercise according to the training needs and their own conditions.

[0030] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacements or changes within the technical scope disclosed in the present application according to the technical solution and concept of the present application, which should be covered within the protection scope of the present application.
