[0042] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0043] Embodiment one:

[0044] Reference Figures 1-6The embodiment of the application discloses a handgrip, which comprises a handle 1, a first elastic member 3 and a rotating handle 2. The handle 1 is provided with a rotating connecting point, and the top of the handle 1 is provided with a connecting end 100. The top of the rotating handle 2 is provided with a connecting arm 200 which is rotatably connected with the handle 1. The connecting arm 200 is rotatably connected with the rotating connecting point. The two ends of the first elastic member 3 are respectively connected with the connecting end 100 and the connecting arm 200. Specifically, the connecting arm 200 is provided with a sliding block 4 which slides along the length direction of the connecting arm 200 and a first driving mechanism 5 which drives the sliding block 4 to slide. One end of the first elastic member 3 is connected with the connecting end 100 at the top of the handle 1, and the other end of the first elastic member 3 is connected with the sliding block 4. The rotating handle 2 is driven to rotate, so that the rotating handle 2 rotates around the circumferential direction of the rotating connecting point, thereby stretching the first elastic member 3 through the connecting arm 200. The first elastic member 3 exerts resistance on the rotating handle 2, thereby achieving the purpose of handgrip training.

[0045] In the embodiment, the handle 1 is provided with a rotating connecting point, which can be a rotating shaft, a rotating hole or the like, for providing the rotating connection of the rotating handle. Referring to Figure 1 and Figure 2 The handle 1 is connected with a connecting seat 102 on the side close to the rotating handle 2. The connecting seat 102 is provided with a rotating connecting point. The connecting arm 200 of the rotating handle 2 is rotatably connected with the rotating connecting point of the connecting seat 102. In this way, the rotating range of the rotating handle 2 can be larger, the use is more convenient, and the connecting stability of the rotating handle 2 is high.

[0046] Specifically, in the embodiment, the connecting arm 200 is integrally formed with the rotating handle 2, and the connecting arm 200 is hollow and provided with a sliding groove 201 which extends along the length direction of the connecting arm 200. An adjusting rod 500 is arranged in the sliding groove 201 and along the length direction of the sliding groove 201. The adjusting rod 500 is rotatably connected in the sliding groove 201. The adjusting rod 500 is provided with external threads along the axial direction. The sliding block 4 is provided with a threaded hole which is threadedly connected with the adjusting rod 500. The sliding block 4 is circumferentially limited in the sliding groove 201. When the adjusting rod 500 rotates, the sliding block 4 which is threadedly connected with the adjusting rod 500 moves along the axial direction of the adjusting rod 500, so as to stretch the first elastic member 3, thereby adjusting the elastic force of the first elastic member 3 and the gripping force of the handgrip.

[0047] It is understandable that when the adjusting rod 500 is rotated to move the sliding block 4 to the side close to the handle 1, the first elastic member 3 is in a state of being stretched or in a state of not being stretched, and the maximum grip strength of the grip strengthener is reduced; conversely, when the adjusting rod 500 is rotated to move the sliding block 4 to the side away from the handle 1, the first elastic member 3 is stretched, and the maximum grip strength of the grip strengthener is increased, until the sliding block 4 is moved to the limit position of the outer end of the sliding groove 201, and the maximum grip strength of the grip strengthener reaches the limit or maximum. Therefore, in the embodiment, the first driving mechanism 5 can be used to adjust the grip strength of the grip strengthener; in order to facilitate the user to adjust the grip strength, the outer end of the adjusting rod 500 of the first driving mechanism 5 extends out of the connecting arm 200, and the outer end of the adjusting rod 500 is connected with the first knob 501 for driving the adjusting rod 500 to rotate. The user can adjust the position of the sliding block 4 through the first knob 501, so that the grip strength of the grip strengthener is adjusted more conveniently.

[0048] In the embodiment, the grip strengthener further comprises a second elastic member connected to the handle, and the rotating handle is drivingly connected with the second elastic member, and when the rotating handle is rotated to the direction close to the handle, the rotating handle is provided with resistance. Referring to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the connecting arm 200 is provided with a driving part 202 rotating synchronously with the connecting arm 200; the handle 1 is connected with a rotating arm 7 and a second elastic member 8, wherein the rotating arm 7 has a first end and a second end opposite to the first end, the middle part of the rotating arm 7 is rotatably connected to the handle 1 through a hinge pin, and the first end of the rotating arm 7 abuts against the driving part 202 on the connecting arm 200, for driving the rotating arm 7 to rotate when the rotating handle 2 is rotated; specifically, when the rotating handle 2 is rotated to the handle 1 around the rotating shaft, the driving part 202 on the rotating handle is rotated upward, so that the first end of the rotating arm 7 is rotated upward with the hinge pin of the rotating arm 7 as the rotating fulcrum, and the second end of the rotating arm 7 is rotated downward. The second elastic member 8 is used to provide resistance to the downward rotation of the second end of the rotating arm 7.

[0049] For example, referring to Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the connecting arm 200 of the rotating handle 2 is rotatably connected to the handle 1 at the end close to the handle 1, the end of the connecting arm 200 close to the handle 1 is provided with a groove 203, and the bottom of the groove 203 is provided with a protrusion extending towards the handle 1, and the protrusion forms a driving part 202 on the connecting arm 200. The rotating arm 7 is in a strip or rod shape, and is arranged transversely relative to the handle 1, the middle part of the rotating arm 7 is rotatably connected to the handle 1 through a hinge pin, the first end of the rotating arm 7 extends out of the handle 1 and is arranged in the groove 203 of the connecting arm 200 and abuts against the protrusion at the bottom of the groove 203; the inside of the handle 1 is hollow, and is provided with a second elastic member 8 along the length direction of the handle 1, and when the rotating handle 2 rotates, the driving part 202 rotates upwards to drive the first end of the rotating arm 7 to rotate upwards. In this way, when the rotating handle 2 rotates, the second end of the rotating arm 7 can be driven to rotate downwards by the driving part 202, that is, the second end of the rotating arm 7 compresses the second elastic member 8 downwards, and the elastic force generated by the passive compression of the second elastic member 8 provides resistance to the rotation of the rotating handle 2.

[0050] In the above embodiment, the grip strength of the grip strengthener can be adjusted by adjusting the sliding position of the sliding block 4 through the first driving mechanism 5 to adjust the stretching length of the first elastic member 3, so as to realize the adjustment of the grip strength of the grip strengthener; the grip strengthener is provided with the rotating arm 7 and the second elastic member 8 on the handle 1, the middle part of the rotating arm 7 is rotatably connected to the handle 1, and when the rotating handle 2 rotates, the driving part 202 on the rotating handle 2 can drive the rotating arm 7 to rotate, and the second elastic member 8 is used to provide resistance to the rotation of the rotating arm 7; that is, in addition to the first driving mechanism 5 driving the adjustment of the stretching length of the first elastic member 3 to realize the adjustment of the grip strength, the grip strengthener can also increase the grip strength by applying resistance to the rotation of the rotating handle 2 through the second elastic member 8. Therefore, the resistance applied by the second elastic member 8 to the rotation of the rotating handle 2 can be superimposed with the grip strength provided by the first elastic member 3, so as to improve the maximum grip strength or the highest limit grip strength of the grip strengthener, increase the grip strength range, meet the needs of different users, and have good universality.

[0051] It can be understood that in the above embodiment, the driving part 202 of the rotating handle 2 drives the rotating arm 7 to rotate, and the second elastic member 8 is used to provide resistance to the rotation of the rotating arm 7, that is, the elastic force of the second elastic member 8 can provide resistance to the rotation of the rotating arm 7, and similarly provide resistance to the rotation of the rotating handle 2; wherein the rotation of the rotating handle 2 is that the force applied by the user on the rotating handle 2 drives the rotating handle 2 to rotate, or the rotating handle 2 rotates towards the handle 1.

[0052] It can be understood that the second elastic member 8 is used to provide resistance to the rotation of the rotating arm 7. There can be the following cases. In the first case, the upper end of the second elastic member 8 abuts against the second end of the rotating arm 7, and the lower end of the second elastic member 8 abuts against the handle 1. When the handle 2 is rotated from the initial state to the direction close to the handle 1, the second elastic member 8 can provide resistance to the rotation of the rotating arm 7. In the second case, there is a free space between the upper end of the second elastic member 8 and the second end of the rotating arm 7. When the handle 2 drives the rotating arm 7 to rotate to the state that the second end of the rotating arm 7 abuts against the upper end of the second elastic member 8, the second elastic member 8 can provide resistance to the rotation of the rotating arm 7.

[0053] In the embodiment, the second elastic member 8 is in the form of a compression spring, that is, is compressed to generate elastic force to provide resistance to the rotation of the handle 2. In other embodiments, the second elastic member can also be in the form of a tension spring, that is, is stretched when the rotating arm 7 is driven to rotate, and the stretched second elastic member provides resistance to the rotation of the rotating arm.

[0054] In the embodiment, the first elastic member 3 and the second elastic member 8 are both columnar helical springs.

[0055] In the related art, if the maximum grip strength of the grip strengthener is to be improved, a spring with a high stiffness coefficient must be selected, which results in the increase of the minimum grip strength of the grip strengthener, thereby reducing the use comfort of the grip strengthener. In the above embodiment, the second elastic member provides resistance to the rotation of the rotating arm, thereby increasing the maximum grip strength or the highest limit grip strength of the grip strengthener, which also results in the increase of the minimum grip strength of the grip strengthener, thereby affecting the use comfort. Therefore, in the embodiment, as shown in Figure 3 In other words, when the rotating arm 7 is in the initial position, if the second elastic member 8 is moved to be separated from the second end of the rotating arm 7. That is, when the rotating arm 7 is in the initial position, the second elastic member 8 does not generate elastic force or resistance to the second end of the rotating arm 7. Only when the second end of the rotating arm 7 is rotated downward by a certain distance to abut against the second elastic member 8, the second elastic member 8 provides resistance to the rotation of the rotating arm 7. In this way, when the rotating arm 7 is driven to rotate downward from the initial position, the minimum grip strength of the grip strengthener is not affected by the second elastic member 8. Therefore, when the maximum grip strength or the highest limit grip strength of the grip strengthener is improved, the grip strength adjustment range of the grip strengthener is larger, and the minimum grip strength of the grip strengthener can be kept unchanged, thereby improving the use comfort of the grip strengthener.

[0056] Further, the second elastic member 8 is movably connected in the handle 1, and the handle 1 is connected with a second driving mechanism 6 for driving the second elastic member 8 to move to compress or release the second elastic member 8. The second driving mechanism 6 has various structures, for example, a slot is arranged on the handle 1 along the length direction of the handle 1 and corresponding to the second elastic member, and a driving block is slidably connected in the slot, the inner end of the driving block is connected with the bottom of the second elastic member, and the driving block is pushed to drive the second elastic member to move; or a top rod is arranged on the handle and can be screwed into the handle, the end of the top rod is connected with the bottom of the second elastic member, and the second elastic member is driven to move by rotating the top rod. In the embodiment, as shown in Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the second driving mechanism 6 comprises a rotating rod 600 rotatably connected on the handle 1, a moving block 601 is threadedly connected on the rotating rod 600, and the moving block 601 is circumferentially limited in the handle 1; the second elastic member 8 is sleeved on the rotating rod 600 between the rotating arm 7 and the moving block 601, the lower end of the second elastic member 8 abuts against the moving block 601 and can synchronously move with the moving block 601, and the upper end of the second elastic member 8 abuts against the second end of the rotating arm 7. The second driving mechanism 6 can drive the second elastic member 8 to move to adjust the position or the elastic force of the second elastic member 8; when the grip strength of the grip strengthener is adjusted, because the moving block 601 threadedly connected on the rotating rod 600 is circumferentially limited in the handle 1, the moving block 601 moves along the axial direction of the rotating rod 600 when the rotating rod 600 is rotated, the moving block 601 drives the second elastic member 8 to slide towards the rotating arm 7, so that the second elastic member 8 abuts against the second end of the rotating arm 7, or the compression height of the second elastic member 8 is adjusted after abutting, so that the maximum grip strength of the grip strengthener is improved; the rotating rod 600 is reversely rotated, the moving block 601 moves reversely along the axial direction of the rotating rod 600, so that the second elastic member 8 is released from the compression state or the second elastic member 8 is separated from the rotating arm 7. The second driving mechanism 6 has simple structure, and is convenient and stable to adjust.

[0057] In some embodiments, in order to make the rotating arm 7 rotate more stably, as shown in Figure 3 , a positioning slot 700 is arranged on the second end of the rotating arm 7 and is insertedly fitted on the rotating rod 600. Therefore, the inserted fitting of the positioning slot 700 on the rotating arm 7 and the rotating rod 600 makes the rotating arm 7 rotate more stably when being driven to rotate.

[0058] In the above embodiment, the moving block 601 is circumferentially limited in the handle 1, as shown in Figure 2 and Figure 4As shown, the handle 1 is provided with a sliding groove 101 along the length direction, and the moving block 601 is provided with a radially outward protruding protruding portion 602, which is slidingly connected in the sliding groove 101. Specifically, in the embodiment, the front and rear side walls of the handle 1 are provided with the sliding grooves 101, and the two sides of the moving block 601 are provided with the outward protruding protruding portions 602, which are slidingly connected in the two sliding grooves 101. In this way, the movement of the moving block 601 is more stable, and the structure is stable.

[0059] In some embodiments, in order to facilitate the user to adjust the grip strength, one end of the rotating rod 600 of the second driving mechanism 6 extends out of the handle 1, and the extending end of the rotating rod 600 is connected with a second knob 603 for driving the rotating rod 600 to rotate. The user can rotate the rotating rod 600 through the second knob 603 to adjust the position or compression amount of the second elastic member 8, so that the grip strength of the grip strengthener is adjusted more conveniently.

[0060] Embodiment two:

[0061] Referring to Figures 7-11 As shown, the handle 1 is provided with a sliding groove 101 along the length direction, and the moving block 601 is provided with a radially outward protruding protruding portion 602, which is slidingly connected in the sliding groove 101. Specifically, in the embodiment, the front and rear side walls of the handle 1 are provided with the sliding grooves 101, and the two sides of the moving block 601 are provided with the outward protruding protruding portions 602, which are slidingly connected in the two sliding grooves 101. In this way, the movement of the moving block 601 is more stable, and the structure is stable.

[0062] For example, referring to Figure 9 , Figure 10 and Figure 11 As shown, the end of the connecting arm 200 of the rotating handle 2 close to the handle 1 is rotationally connected with the rotating connection point on the handle 1 through a rotating shaft, and the end face of the end of the connecting arm 200 close to the handle 1 is provided with a segment of arc-shaped distributed teeth along the circumference of the rotating shaft, which is the first tooth portion 203 in the embodiment. The inside of the handle 1 is hollow, and is provided with the sliding member 10 and the second elastic member 8 along the length direction of the handle 1. The sliding member 10 is in a strip shape, and the side wall of the sliding member 10 close to the first tooth portion 203 is provided with the teeth distributed along the length direction of the sliding member 10, which forms the second tooth portion 1000 of the sliding member 10, that is, the side wall of the sliding member 10 close to the first tooth portion 203 is provided with an elongated gear rack. Since the first tooth portion 203 and the second tooth portion 1000 are in transmission connection, when the rotating handle 2 rotates, the first tooth portion 203 drives the sliding member 10 to slide through the second tooth portion 1000.

[0063] Furthermore, a transmission gear 9 is rotatably connected within the handle 1, and the transmission gear 9 meshes with the first tooth portion 203 and the second tooth portion 1000 respectively. With this configuration, when the handle 2 is rotated, the transmission gear 9 causes the sliding member 10 to slide downwards, that is, to slide away from the top connecting end 100 of the handle 1, so as to compress the second elastic member 8. The elastic force generated by the passive compression of the second elastic member 8 provides resistance to the rotation of the handle 2.

[0064] It is easy to understand that in this embodiment, rotating the handle 2 causes the slider 10 to slide, and the second elastic element 8 is used to provide resistance to the sliding of the slider 10. That is, the elastic force of the second elastic element 8 can generate resistance to the sliding of the slider 10, and similarly, rotating the handle 2 provides resistance. The second elastic element 8 can provide resistance to the sliding of the slider 10 in the following ways: First, the upper end of the second elastic element 8 abuts against the slider 10, and the lower end of the second elastic element 8 abuts against the handle 1. When rotating the handle 2 from the initial state toward the direction closer to the handle 1, the second elastic element 8 can provide resistance to the sliding of the slider 10. Second, there is a free space between the upper end of the second elastic element 8 and the slider 10. When rotating the handle 2 causes the slider 10 to slide until the slider 10 abuts against the upper end of the second elastic element 8, the second elastic element 8 can provide resistance to the sliding of the slider 10.

[0065] Furthermore, when the slider 10 is in its initial position, if the second elastic element 8 is moved to disengage from the slider 10, that is, when the slider 10 is in its initial position, the second elastic element 8 does not generate elastic force or resistance to the slider 10. Only when the slider 10 slides a certain distance and comes into contact with the second elastic element 8 does the second elastic element 8 provide resistance to the sliding of the slider 10. In this way, when the slider 10 is driven to slide downward from its initial position, the minimum grip force of the grip strengthener is not affected by the second elastic element 8. Therefore, while increasing the maximum grip force value or the highest limit grip force value to make the grip force range of the grip strengthener wider, the minimum grip force can remain unchanged, thereby improving the comfort of using the grip strengthener.

[0066] In some embodiments, to make the slider 10 slide more smoothly, see [reference needed]. Figure 10 As shown, a guide groove 1001 is provided on the slider 10, and the guide groove 1001 is inserted into the rotating rod 600. Therefore, the insertion and engagement of the guide groove 1001 on the slider 10 and the rotating rod 600 makes the slider 10 slide more smoothly when it is driven to slide.
