Description

Technical Field

[0001] The present invention relates to the technical field of adjustable grip strengtheners, and particularly to a grip training device with adjustable poundage. Background Art

[0002] With the accelerating pace of modern life, hand strength training has gradually become a health issue of public concern. Its application scope is relatively wide. For example, whether it is fitness enthusiasts improving hand muscle endurance, office workers relieving hand fatigue, or hospital patients needing to promote upper limb blood circulation through grip training to reduce the risk of venous thrombosis, a grip strengthener is required. However, the common traditional grip strengtheners on the market (such as grip balls and spring-type grip strengtheners) generally have the following pain points: 1. Fixed resistance and poor adaptability. Traditional devices cannot accurately adjust the resistance intensity and are difficult to meet the needs of different users. For example, fitness beginners need low-resistance entry training, while professional users need to gradually increase the intensity to break through the strength bottleneck. The design of fixed resistance limits the training effect.

[0003] 2. Lack of data feedback. Most devices are not equipped with counting or force monitoring functions during training. Users cannot quantify the training results (such as the number of grip times and peak intensity), nor can they judge the action standardization. Long-term training is likely to cause muscle strain due to fatigue or incorrect postures.

[0004] 3. When held for a long time, it is easy to slip due to hand sweat, affecting the safety and continuity of training. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a grip training device with adjustable poundage, which solves the above problems.

[0006] The present invention provides the following technical solutions: A grip training device with adjustable poundage, including a grip strengthener body. Two fixing belts are fixedly connected to the outer wall of the grip strengthener body. A magnetic counter is provided at the upper end of the outer side wall of the grip strengthener body. Adjusting components are provided on both sides of the outer wall of the grip strengthener body; The adjusting component includes a fixing box located on the outer wall of the grip strengthener body. A connecting plate is fixedly provided on one side of the outer wall of the fixing box, and the connecting plate is arc-shaped. A plurality of pressing cylinders are provided at the bottom of the connecting plate. Springs are provided in the plurality of pressing cylinders. A display light bar is fixedly connected to the outer wall of the connecting plate. A moving component is provided in the inner wall of the fixing box; The moving component includes a torsion spring located on the inner wall of the fixed box. The top of the outer wall of the torsion spring is rotatably connected to a pressing handle. The surface of the pressing handle is provided with a plurality of placement grooves. The inner wall of the torsion spring is provided with a threaded rod, which penetrates through the entire torsion spring. A limiting plate is arranged on the outer wall of the threaded rod on the side close to the torsion spring. The limiting plate is slidably connected to the fixed box. The upper end of the outer wall of the threaded rod is rotatably connected to an adjusting disc. Grooves are formed at one end of both sides of the outer wall of the fixed box close to the adjusting disc. A fixed block is fixedly arranged on the outer wall of the fixed box at one end close to the groove. A clamping plate is slidably connected to the outer wall of the fixed block, and the clamping plate is clamped with the adjusting disc. A connecting rod is fixedly arranged at the bottom of the fixed block, and an anti-slip component is arranged on the outer wall of the connecting rod.

[0007] Preferably: A chute is formed at the top of the outer wall of the fixed box close to the torsion spring, and the pressing handle slides up and down in the chute.

[0008] Preferably: The position of the pressing handle corresponds to the position of the connecting plate, and both the pressing handle and the connecting plate are arc-shaped.

[0009] Preferably: The position of the adjusting disc corresponds to the limiting plate. When the adjusting disc moves at the top of the outer wall of the threaded rod, the limiting plate limits the moving distance of the adjusting disc.

[0010] Preferably: The anti-slip component includes a placement plate located on the outer wall of the connecting rod. A rotating cylinder is rotatably connected to the inner wall of the placement plate. An arc-shaped rod is fixedly arranged at the top of the outer wall of the rotating cylinder. A plurality of anti-slip pads are arranged at the top of the arc-shaped rod. An extension block is arranged at the bottom of the outer wall of the rotating cylinder, and the extension block is fixed to the bottom of the outer wall of the connecting rod. A plurality of limiting holes are formed on the surface of the placement plate, and the positions of the plurality of limiting holes correspond to the positions of the plurality of anti-slip pads arranged at the top of the arc-shaped rod.

[0011] Preferably: The placement plate is fixedly connected to the connecting plate and has a matching shape.

[0012] Preferably: Adjusting belts are arranged at the bottoms of the two fixing belts, and the adjusting belts are matched in size with the fixing belts.

[0013] Preferably: Magnetic blocks are arranged inside the grip strength exerciser body at positions corresponding to the magnetic counters.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The poundage-adjustable grip trainer has a constant inflation volume within the grip trainer body, and the grip trainer body is made of rubber. Since the positions of the pressing handle and the connecting plate correspond to each other, when the pressing handle squeezes the connecting plate, it will cause deformation of the grip trainer body. When the grip trainer body is squeezed to fill the arc-shaped cavity at the bottom end of the side wall of the connecting plate, the degree to which the pressing cylinder is pushed is displayed on the display light bar provided on the outer wall of the connecting plate. By observing the display light bar, it is possible to determine whether the current resistance of the grip trainer is suitable for the required strength, avoiding the inability to accurately evaluate the training frequency and intensity, resulting in low training compliance, and the inability to achieve the expected effect of preventing blood clots due to fatigue or incorrect movements in some cases. Moreover, a magnetic block is provided within the grip trainer body, and data is recorded on the magnetic counter displayed on the top of the side wall of the grip trainer body after extrusion, effectively assisting the display light bar and enabling the user to observe accurately.

[0015] 2. The poundage-adjustable grip trainer has a plurality of anti-slip pads made of rubber at the top of the arc-shaped rod. When the connecting rod squeezes the extension plate connected to the bottom end of the rotating cylinder downward, the arc-shaped rod can be lifted upward as the rotating cylinder rotates. When the resistance of the grip trainer needs to be increased during training, the higher the arc-shaped rod is lifted. When the palm is placed on the placement plate, the higher the arc-shaped rod rises from the limiting hole, effectively increasing the friction during training and preventing the occurrence of slipping due to sweating of the palm caused by repeated movements. As the resistance of the grip trainer decreases, the lifting height of the arc-shaped rod also decreases, preventing the arc-shaped rod from being lifted too high uniformly during initial training, resulting in incorrect movements and the inability to effectively improve the rehabilitation effect.

[0016] 3. Since different people need to adapt to grip trainers with different resistances, to prevent people with relatively small grip strength during the recovery period from being unable to adapt to grip trainers with relatively large resistance during rehabilitation training, or grip trainers with too small resistance being unable to provide sufficient resistance, causing patients to be unable to achieve the expected effect of preventing blood clots, the adjustment disc rotates on the threaded rod, pushing the limiting plate to squeeze the torsion spring provided at the bottom end of the threaded rod, and adjusting the resistance to a strength suitable for the current training of the population.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0020] Please refer to Figure 1-8 , a poundage-adjustable grip trainer, including a gripper body 1, two fixing belts 2 are fixedly connected to the outer wall of the gripper body 1, a magnetic counter 3 is arranged at the upper end of the outer side wall of the gripper body 1, and adjusting components 5 are arranged on both sides of the outer wall of the gripper body 1 The adjusting component 5 includes a fixing box 51 located on the outer wall of the gripper body 1, a connecting plate 53 is fixedly arranged on one side of the outer wall of the fixing box 51, and the connecting plate 53 is arc-shaped. A plurality of pressing cylinders 55 are arranged at the bottom of the connecting plate 53. Springs are arranged in the plurality of pressing cylinders 55. A display light bar 54 is fixedly connected to the outer wall of the connecting plate 53. A mobile component 7 is arranged inside the inner wall of the fixing box 51 The moving component 7 includes a torsion spring 71 located on the inner wall of the fixed box 51. The top end of the outer wall of the torsion spring 71 is rotatably connected to a pressing handle 52. Multiple placement grooves are provided on the surface of the pressing handle 52. A threaded rod 72 is provided on the inner wall of the torsion spring 71. The threaded rod 72 penetrates through the entire torsion spring 71. A limiting plate 73 is provided on the outer wall of the threaded rod 72 on the side close to the torsion spring 71. The limiting plate 73 is slidably connected to the fixed box 51. The upper end of the outer wall of the threaded rod 72 is rotatably connected to an adjusting disc 74. Grooves are opened at both ends of the outer wall of the fixed box 51 close to the adjusting disc 74. A fixed block 76 is fixedly provided on the outer wall of the fixed box 51 close to the groove. A clamping plate 75 is slidably connected to the outer wall of the fixed block 76, and the clamping plate 75 is clamped with the adjusting disc 74. A connecting rod 77 is fixedly provided at the bottom of the fixed block 76. An anti-slip component 6 is provided on the outer wall of the connecting rod 77.

[0021] In an alternative embodiment: A chute is opened on the outer wall of the fixed box 51 close to the top of the torsion spring 71. The pressing handle 52 slides up and down in the chute.

[0022] It should be noted that when adjusting the resistance to be adapted to the current training of the crowd, since the pressing handle 52 is fixedly provided at the top of the torsion spring 71, after adjusting to the appropriate resistance, pressing the pressing handle 52 back and forth can be used for training. Moreover, a chute is opened on the outer wall of the fixed box 51 close to the top of the torsion spring 71, and the pressing handle 52 slides up and down in the chute. The chute effectively limits the pressing handle 52, improving the accuracy of the device.

[0023] In an alternative embodiment: The position of the pressing handle 52 corresponds to the position of the connecting plate 53, and both the pressing handle 52 and the connecting plate 53 are arc-shaped.

[0024] It should be noted that since the position of the pressing handle 52 corresponds to the position of the connecting plate 53, when the pressing handle 52 moves downward, it can push and squeeze the connecting plate 53.

[0025] In an alternative embodiment: The position of the adjusting disc 74 corresponds to the position of the limiting plate 73. When the adjusting disc 74 moves on the top end of the outer wall of the threaded rod 72, the limiting plate 73 limits the moving distance of the adjusting disc 74.

[0026] In an alternative embodiment: The anti-slip component 6 includes a placement plate 61 located on the outer wall of the connecting rod 77. A rotating cylinder 63 is rotatably connected to the inner wall of the placement plate 61. An arc-shaped rod 64 is fixedly provided at the top of the outer wall of the rotating cylinder 63. Multiple anti-slip pads are provided on the top of the arc-shaped rod 64. An extension block is provided at the bottom of the outer wall of the rotating cylinder 63, and the extension block is fixed to the bottom of the outer wall of the connecting rod 77. Multiple limiting holes 62 are opened on the surface of the placement plate 61, and the positions of the multiple limiting holes 62 correspond to the positions of the multiple anti-slip pads provided on the top of the arc-shaped rod 64.

[0027] It should be noted that one end of the connecting rod 77 is fixed with an arc rod 64, and a plurality of anti-slip pads made of rubber are provided on the top of the arc rod 64. When the connecting rod 77 presses down on the extension plate connected to the bottom end of the rotating cylinder 63, the arc rod 64 can be lifted upward as the rotating cylinder 63 rotates. When the resistance of the gripper is required to be increased during the training of the crowd, the higher the arc rod 64 is lifted. When the palm is placed on the placing plate 61, the higher the arc rod 64 rises from the limiting hole 62, effectively increasing the friction force during the training of the crowd, preventing the palm from sweating due to repeated movements and causing the phenomenon of slipping. As the resistance of the gripper decreases, the lifting height of the arc rod 64 also decreases, preventing the arc rod 64 from being lifted too high during the initial training of the crowd, resulting in non-standard movements and unable to effectively improve the rehabilitation effect.

[0028] In an alternative embodiment: The placing plate 61 and the connecting plate 53 are fixedly connected and have matching shapes.

[0029] It should be noted that the placing plate 61 and the connecting plate 53 are fixedly connected and have matching shapes, which is convenient for the palm of the crowd to fit with the placing plate 61 during rehabilitation training, increasing the friction force and preventing the gripper from falling due to sweating of the palm.

[0030] In an alternative embodiment: Adjusting straps 4 are provided at the bottom of the two fixing straps 2, and the adjusting straps 4 are matched with the fixing straps 2 in size.

[0031] It should be noted that tightening the adjusting strap 4 at the bottom of the gripper body 1 ensures that the gripper is not easily dropped during training.

[0032] In an alternative embodiment: A magnetic block is provided inside the gripper body 1 at a position corresponding to the magnetic counter 3.

[0033] It should be noted that the data is recorded on the magnetic counter 3 displayed on the top side wall of the gripper body 1 after extrusion, effectively assisting the display light bar 54 and enabling the user to observe accurately.

[0034] Working principle: Before using the gripper, since different people need to adapt to grippers with different resistances, to prevent people with relatively small grip strength during the recovery period from being unable to adapt to grippers with large resistances during rehabilitation training, or grippers with too small resistances being unable to provide large resistances for people, resulting in people being unable to achieve the expected effect of preventing blood clots, the device can be adjusted according to the basic conditions of different people. Pass the palm through the fixing strap 2 provided on the outer wall of the gripper body 1 and place it on the surface of the pressing handle 52. Since there are multiple placement grooves on the surface of the pressing handle 52, it prevents slipping caused by sweating on the palm during training. Tighten the adjusting strap 4 at the bottom of the gripper body 1 to ensure that the gripper is not easily dropped during training. At this time, rotate the adjusting disc 74 on the outer wall of the fixed box 51. The adjusting disc 74 rotates on the threaded rod 72, pushing the limiting plate 73 to squeeze the torsion spring 71 provided at the bottom of the threaded rod 72, and adjust the resistance to the intensity suitable for the current training of the people. Since the pressing handle 52 is fixedly provided at the top of the torsion spring 71, after adjusting to the appropriate resistance, repeatedly press the pressing handle 52 to conduct training; The inflation volume in the gripper body 1 is constant, and the gripper body 1 is made of rubber. Since the positions of the pressing handle 52 and the connecting plate 53 correspond to each other, when the pressing handle 52 squeezes the connecting plate 53, it will cause deformation of the gripper body 1. When the gripper body 1 is squeezed to fill the arc-shaped cavity at the bottom end of the side wall of the connecting plate 53, the degree to which the pressing cylinder 55 is pushed is displayed on the display light bar 54 provided on the outer wall of the connecting plate 53. The user can judge whether the current resistance of the gripper is suitable for the strength required by the people by observing the display light bar 54, avoiding the situation where the user cannot accurately evaluate the training frequency and intensity of the people, resulting in low training compliance, and some people being unable to achieve the expected effect of preventing blood clots due to fatigue or incorrect movements. And there is a magnetic block in the gripper body 1, and the data is recorded on the magnetic counter 3 at the top of the side wall of the gripper body 1 after extrusion, effectively assisting the display light bar 54 for accurate observation; Since the adjustment disc 74 is clamped with the clamping plate 75, when the adjustment disc 74 moves, the clamping plate 75 drives the connecting rod 77 to slide up and down. Since the connecting rod 77 is located on the inner wall of the placing plate 61, one end of the connecting rod 77 is fixed with an arc-shaped rod 64. A plurality of anti-slip pads made of rubber are provided on the top of the arc-shaped rod 64. When the connecting rod 77 presses down the extension plate connected to the bottom end of the rotating cylinder 63, the arc-shaped rod 64 can be lifted upward as the rotating cylinder 63 rotates. When the resistance of the gripper is required to be increased during the training of the crowd, the higher the arc-shaped rod 64 is lifted. When the palm is placed on the placing plate 61, the higher the arc-shaped rod 64 rises from the limiting hole 62, effectively increasing the friction force of the crowd during training and preventing the palm from sweating due to repeated movements, resulting in a slipping phenomenon. As the resistance of the gripper decreases, the lifting height of the arc-shaped rod 64 also decreases, preventing the lifting height of the arc-shaped rod 64 from being unified, resulting in an excessive lifting height of the arc-shaped rod 64 during the initial training of the crowd, causing unstandardized movements and unable to effectively improve the rehabilitation effect.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
