Description

Technical Field

[0001] This utility model belongs to the field of grip strength device technology, and specifically relates to a grip strength device with lateral movement. Background Technology

[0002] A hand gripper, also known as an arm gripper, hand gripper, finger gripper, or force meter, is a training device used to improve hand strength.

[0003] Most hand grip strengtheners on the market include a first handle and a second handle that are rotatably connected, with a spring between them. For example, the grip adjustment mechanism of the hand grip strengthener disclosed in Chinese Utility Model Patent CN 202322739948.6 includes a first handle, a rotating component, a second handle, a bolt, and a tension knob. The rotating component is pivotally connected to the middle section of the first handle, and its lower surface has a first sliding groove extending along its length. One end of the first sliding groove extends to the end of the rotating component, and both sides of its lower opening have limiting flanges. Adjustment holes are formed through both sides of the first sliding groove, and these adjustment holes are parallel to the first sliding groove. The upper end of the second handle has a slider that slides within the first sliding groove and is prevented from disengaging by the limiting flanges. The bolt passes through the adjustment hole on one side into the first sliding groove, through the slider, and out through the adjustment hole on the other side, before being threadedly connected to a nut embedded in the tension knob.

[0004] The above structure is stable and safe to use. However, when using this hand gripper, each finger gradually moves away from the rotation center of the second handle. During use, the exercise distance of the index, middle, ring, and little fingers increases in sequence, affecting the exercise effect of each finger. In addition, the little finger is not convenient to grasp the second handle during exercise, making it inconvenient for the user to use. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a lateral movement grip strengthener that is convenient for users to use and has good training effect.

[0006] The purpose of this utility model is achieved as follows:

The elastic element can drive the second gripping part away from the first gripping part. The handle body has a guide rod, and the movable handle has a guide hole adapted to the guide rod. The guide hole slides along the guide rod, causing the second gripping part to move away from or closer to the first gripping part. The handle body has an adjustment device, and the elastic element is disposed between the adjustment device and the movable handle. The adjustment device can control the deformation of the elastic element to adjust the damping magnitude during the movement of the movable handle.

[0008] The present invention is further configured such that: the adjustment device includes a first knob rotatably disposed on the grip body, a push plate threadedly connected to the first knob, the push plate being slidably connected to the grip body, and an elastic element abutting against the push plate; rotating the first knob causes the push plate to slide relative to the grip body and drive the elastic element to deform.

[0009] The present invention is further configured such that: the guide rod is provided with an installation cavity, the elastic element and the push plate are both provided in the installation cavity, and an observation port is provided on the side wall of the installation cavity, through which the relative position of the push plate in the installation cavity can be observed directly or indirectly.

[0010] The present invention is further configured such that: a guide groove is provided on the side wall of the mounting cavity, a connecting protrusion is provided on the movable handle, the connecting protrusion passes through the guide groove and enters the mounting cavity, one end of the elastic element abuts against the connecting protrusion, and the other end of the elastic element abuts against the push plate.

[0011] The present invention is further configured such that: a limiting device is provided on the grip body to limit the range of motion of the movable handle, the limiting device including a limiting block slidably disposed on the grip body and an adjusting member for adjusting the relative position of the limiting block on the grip body, the adjusting member being able to control the limiting block to slide on the grip body along the extension direction of the guide rod.

[0012] The present invention is further configured such that: the adjusting member is rotatably mounted on the grip body, and the adjusting member is threadedly connected to the grip body; rotating the adjusting member drives the limiting block to slide along the extension direction of the guide rod.

[0013] The present invention is further configured such that: a damping element is provided on the grip body or adjustment device, and an annular anti-slip part adapted to the damping element is provided on the adjustment element, the damping element abuts against the annular anti-slip part and provides damping for the rotation of the adjustment element.

[0014] The present invention is further configured such that a support roller is rotatably provided on the side wall of the guide hole, and the support roller abuts against the guide rod to reduce the friction between the guide rod and the guide hole.

[0015] The present invention is further configured such that: the front end of the guide hole is the end away from the first gripping part, the second gripping part is located below the guide hole, and support rollers are provided on the upper front part and the lower rear part of the guide hole.

[0016] The present invention is further configured such that: the guide rod is provided with a guide groove adapted to the support roller; the control handle slides along the guide rod, and the support roller rolls along the guide groove.

[0017] The advantages of this utility model compared to the prior art are:

[0018] 1. In this utility model, the movable handle is slidably connected to the grip body. During use, the movement distance between each position of the first grip part and the second grip part is the same, so that the exercise effect of the index finger, middle finger, ring finger and little finger is similar and the exercise effect is good. Moreover, this structure makes it convenient for the user to grip the second grip part with each finger, making it convenient for the user to use.

[0019] 2. In this utility model, rotating the first knob can drive the elastic element to deform via the push plate, thereby adjusting the damping of the hand gripper. This allows the hand gripper to be suitable for different training intensities, making it convenient for users. Since the push plate is threadedly connected to the first knob, it is easy to fine-tune the push plate, making it convenient for different users. Furthermore, the push plate is not easily displaced under force during use, preventing it from affecting the training effect of the hand gripper. The installation cavity reduces the contact between debris and the elastic element and the push plate, preventing debris from affecting the deformation of the elastic element and the movement of the push plate, making it convenient for users. The observation port allows users to understand the training intensity of the hand gripper, making it convenient for users. The guide groove and connecting protrusion not only facilitate the stable sliding of the movable handle but also facilitate the contact between the elastic element and the movable handle, making it convenient for users.

[0020] 3. The limiting device in this utility model restricts the range of motion of the handle, making it convenient for different users to grip and use. Since the limiting block is slidably mounted on the handle body, it facilitates stable deformation of the elastic element during adjustment, making the limiting device easy to control and adjust. The threaded connection between the adjusting element and the limiting block is simple in structure, facilitating fine-tuning of the limiting block and making it convenient for different users. Furthermore, the limiting block is less likely to shift under stress during use, preventing movement from affecting the user's use of the grip strengthener. Since the adjusting element and limiting block may be unloaded during use, the adjusting element is prone to accidental rotation. The damping element provides resistance to this rotation, preventing accidental rotation and ensuring user convenience.

[0021] 4. The supporting rollers in this invention reduce friction between the guide rod and the guide hole, facilitating relative sliding between the movable handle and the grip body, making it convenient for the user. This structure also reduces wear on the guide rod and guide hole during use, extending the lifespan of the grip strengthener. The supporting rollers located at the upper front and lower rear of the guide hole facilitate contact between the supporting rollers and the guide rod during use, promoting flexible sliding between the movable handle and the grip body. The guide groove facilitates axial sliding of the supporting rollers along the guide rod, improving the stability of the movable handle and grip body and reducing wobbling during use, further enhancing user convenience.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0037] See Figures 1 to 10 As shown, a laterally movable hand gripper includes a grip body 1, a movable handle 2, and an elastic element 6. The grip body 1 has a first gripping portion 11, and the movable handle 2 has a second gripping portion 21. The elastic element 6 can drive the second gripping portion 21 away from the first gripping portion 11. The grip body 1 has a guide rod 12, and the movable handle 2 has a guide hole 22 adapted to the guide rod 12. The guide hole 22 slides along the guide rod 12, causing the second gripping portion 21 to move away from or closer to the first gripping portion 11. An adjustment device 3 is provided on the handle 1, and an elastic element 6 is disposed between the adjustment device 3 and the movable handle 2. The adjustment device 3 can control the deformation of the elastic element 6 to adjust the damping magnitude during the movement of the movable handle 2. In this structure, the movable handle 2 is slidably connected to the grip body 1. During use, the movement distance between each position of the first grip part 11 and the second grip part 21 is the same, so that the exercise effect of the index finger, middle finger, ring finger and little finger is similar and the exercise effect is good. Moreover, this structure makes it convenient for the user to grip the second grip part 21 with each finger, making it convenient for the user to use.

[0038] The adjustment device 3 described in this utility model includes a first knob 31 rotatably mounted on the grip body 1. A push plate 32 is threadedly connected to the first knob 31 and slidably connected to the grip body 1. An elastic element 6 abuts against the push plate 32. Rotating the first knob 31 causes the push plate 32 to slide relative to the grip body 1 and drive the elastic element 6 to deform. In this structure, rotating the first knob 31 can drive the elastic element 6 to deform through the push plate 32, thereby adjusting the damping of the grip strength device. This allows the grip strength device to be suitable for different training intensities, making it convenient for users. Since the push plate 32 is threadedly connected to the first knob 31, it is easy to fine-tune the push plate 32, making it convenient for different users. Furthermore, the push plate 32 is not easily displaced by force during use, thus avoiding the movement of the push plate 32 during use and preventing it from affecting the training effect of the grip strength device.

[0039] The guide rod 12 is provided with a mounting cavity 14, and the elastic element 6 and the push plate 32 are both disposed in the mounting cavity 14. An observation port 15 is provided on the side wall of the mounting cavity 14. The relative position of the push plate 32 in the mounting cavity 14 can be observed directly or indirectly through the observation port 15. The mounting cavity 14 can reduce the contact between debris and the elastic element 6 and the push plate 32, and prevent debris from affecting the deformation of the elastic element 6 and the movement of the push plate 32, which is convenient for users. The observation port 15 makes it easy for users to understand the training intensity of the hand gripper. Preferably, the push plate 32 is slidably connected to the mounting cavity 14.

[0040] In this embodiment, the mounting cavity 14 has an open end for mounting the push plate 32 and the elastic member 6. The open end is detachably provided with an end cap 13. The other end of the mounting cavity 14 is provided with a second hinge hole 141. The first knob 31 includes a first threaded rod 311 threadedly connected to the push plate 32, a control head 312 for controlling the first threaded rod 311, and a second hinge part 314 rotatably connected to the second hinge hole 141.

[0041] In this utility model, a guide groove 16 is provided on the side wall of the mounting cavity 14, and a connecting protrusion 24 is provided on the movable handle 2. The connecting protrusion 24 passes through the guide groove 16 and enters the mounting cavity 14. One end of the elastic member 6 abuts against the connecting protrusion 24, and the other end of the elastic member 6 abuts against the push plate 32. The arrangement of the guide groove 16 and the connecting protrusion 24 not only facilitates the stable sliding of the movable handle 2, but also facilitates the contact between the elastic member 6 and the movable handle 2, making it convenient for the user. In this embodiment, one end of the guide groove 16 extends to the open end. This structure facilitates the disassembly and assembly of the movable handle 2 and the grip body 1.

[0042] The grip body 1 is provided with a limiting device 4 to restrict the range of motion of the movable handle 2. The limiting device 4 includes a limiting block 42 slidably disposed on the grip body 1 and an adjusting member 41 for adjusting the relative position of the limiting block 42 on the grip body 1. The adjusting member 41 can control the limiting block 42 to slide along the extension direction of the guide rod 12 on the grip body 1. The setting of the limiting device 4 can limit the range of motion of the movable handle 2, making it convenient for different users to grip and use. Moreover, since the limiting block 42 is slidably disposed on the grip body 1, it is convenient for the elastic member 6 to deform stably during the adjustment process, and it is convenient for the limiting device 4 to be controlled and adjusted.

[0043] In this invention, the adjusting component 41 is rotatably mounted on the grip body 1 and is threadedly connected to the grip body 1. Rotating the adjusting component 41 drives the limiting block 42 to slide along the extension direction of the guide rod 12. The threaded connection between the adjusting component 41 and the limiting block 42 is simple in structure, facilitates fine adjustment of the limiting block 42, and is convenient for different users. Furthermore, during use, the limiting block 42 is not easily displaced by force, thus preventing the movement of the limiting block 42 from affecting the user's use of the grip strengthener.

[0044] Since the adjusting component 41 and the limiting block 42 may be unloaded during use of the grip strengthener, the adjusting component 41 is prone to accidental rotation. Preferably, the grip body 1 or the adjusting device 3 is provided with a damping component 43, and the adjusting component 41 is provided with an annular anti-slip part 33 adapted to the damping component 43. The damping component 43 abuts against the annular anti-slip part 33 and provides damping for the rotation of the adjusting component 41. The setting of the damping component 43 can provide damping for the rotation of the adjusting component 41, prevent the adjusting component 41 from being easily rotated accidentally, and facilitate the use of the user.

[0045] The limiting device 4 is installed in the mounting cavity 14. The adjusting member 41 includes a detachably connected control end 411 and a second threaded rod 412. The control end 411 is provided with a shaped hole 414, and the second threaded rod 412 is provided with a shaped part 416 adapted to the shaped hole 414. The shaped hole 414 and the shaped part 416 cooperate to enable the control end 411 to drive the second threaded rod 412 to rotate.

[0046] In this embodiment, the limiting block 42 is slidably disposed in the mounting cavity 14. The first knob 31 is provided with a through hole 313. The second threaded rod 412 is rotatably disposed in the through hole 313, and the connecting protrusion 24 is provided with a through hole 25. The second threaded rod 412 passes through the elastic member 6 and the through hole 25 and is connected to the limiting block 42. The end cap 13 is provided with a first hinge hole 131, and the second threaded rod 412 is provided with a first hinge part 417 adapted to the first hinge hole 131.

[0047] The end of the through hole 313 is provided with a groove, and the annular anti-slip part 33 is provided on the side wall of the groove. The first knob 31 is provided with a rotating part 413 that is rotatably connected to the groove. The side wall of the rotating part 413 is provided with a mounting hole 415. The damping element 43 is provided in the mounting hole 415, and the damping element 43 passes through the mounting hole 415 and abuts against the annular anti-slip part 33. In this embodiment, the damping element 43 can be an integral elastomer. The damping element 43 can also include an elastomer and a connector adapted to the annular anti-slip part 33.

[0048] In this invention, a support roller 23 is rotatably provided on the side wall of the guide hole 22. The support roller 23 abuts against the guide rod 12, thereby reducing the friction between the guide rod 12 and the guide hole 22. The provision of the support roller 23 can reduce the friction between the guide rod 12 and the guide hole 22, which facilitates the relative sliding of the movable handle 2 and the grip body 1, making it convenient for the user. Moreover, this structure can reduce the wear of the guide rod 12 and the guide hole 22 during use, which is beneficial to extending the service life of the grip strengthener.

[0049] The front end of the guide hole 22 is away from the first gripping part 11. The second gripping part 21 is located below the guide hole 22. Support rollers 23 are provided on the upper front part and the lower rear part of the guide hole 22. The support rollers 23 located on the upper front part and the lower rear part of the guide hole 22 facilitate contact between the support rollers 23 and the guide rod 12 during use, which is beneficial to the flexible sliding of the movable handle 2 and the grip body 1.

[0050] In this embodiment, the guide rod 12 is provided with a guide groove 17 that is adapted to the support roller 23; the movable handle 2 slides along the guide rod 12, and the support roller 23 rolls along the guide groove 17. The guide groove 17 facilitates the axial sliding of the support roller 23 along the guide rod 12, which is beneficial to the stability of the movable handle 2 and the grip body 1, and reduces the shaking of the movable handle 2 and the grip body 1 during use, making it convenient for the user.

[0051] In this utility model, a counting device 5 is preferably provided on the grip body 1, and a detection head 51 is provided on the counting device 5. A detection part 26 corresponding to the detection head 51 is provided on the movable handle 2. When the grip strengthener is in use, the movable handle 2 is close to the grip body 1, the detection head 51 can detect the detection part 26, and the counting device 5 can perform one count.

[0052] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
