Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grip strengtheners, and more specifically, to a grip strengthener. Background Art
[0002] In vascular access technology, the autogenous arteriovenous fistula (hereinafter referred to as fistula) has become the preferred vascular access method due to its unique advantages, such as good patency, low infection rate, and low medical cost. However, there is a significant drawback after the formation of the fistula, that is, the immaturity problem, which is mainly manifested as insufficient venous diameter or blood flow, thus restricting the immediate use of the fistula.
[0003] The maturation of the fistula is a natural process, usually taking 4 to 12 weeks. To accelerate this process, functional exercise has been proven to be an effective means. Through appropriate exercise, the growth of the blood vessel wall and the increase in blood flow can be stimulated, thereby accelerating the maturation of the fistula.
[0004] Among the existing functional exercise methods, grip training has been widely used because of its simplicity and high acceptance by patients. However, there are also some deficiencies in the design of the current grip strengtheners on the market. One type is the grip strengthener designed for children, whose shape is mostly oval, and the training is achieved by squeezing. Although this type of grip strengthener is convenient for children to use, the internal pressure cannot be adjusted, restricting its applicability and practicability. Another type is the grip strengthener designed for adults. Although the pressure can be adjusted, the hand-held position is relatively large, which is not conducive to children's use.
[0005] Therefore, we propose a grip strengthener to solve the above-mentioned problems. Content of the Utility Model

A restoring assembly is arranged on one side of the slider 10 close to the first bracket body 1, and a fixing assembly is arranged between the slider 10 and the first sliding groove 5.
[0027] In this embodiment, through the design of the adjusting assembly, the grip strengthener can meet the needs of different people at the same time. Whether it is a child with a smaller palm or an adult with a larger palm, the distance between the handle body 4 and the first bracket body 1 can be adjusted through the adjusting assembly to obtain a more comfortable and effective grip training experience. This design not only improves the applicability of the device, but also increases the user's satisfaction and training effect.
[0028] Please refer to Figure 2 and Figure 4 , as shown in the figure, the restoring assembly includes a telescopic rod 17 fixedly installed on one side of the slider 10 close to the first bracket body 1. The telescopic rod 17 is slidably installed on the inner wall of the first sliding groove 5, and a second spring 16 is sleeved on the outer wall of the telescopic rod 17; through the arranged restoring assembly, when the fixing assembly is released, under the action of the second spring 16, the handle body 4 will be pushed to move to the left, so that the handle body 4 returns to the initial position. When the next patient uses it, the position of the handle body 4 can be adjusted according to the size of the patient's palm in cooperation with the fixing assembly, so that the patient is more suitable for himself during use, and the comfort of the patient during the training process is improved.
[0029] Please refer to Figure 4 , as shown in the figure, the fixing assembly includes second tooth blocks 11 arranged on the side wall of the slider 10. There are two groups of second tooth blocks 11. One end of each group of second tooth blocks 11 close to the slider 10 is provided with a connecting plate 12. One end of each group of second tooth blocks 11 away from the slider 10 is embedded between the first tooth blocks 6. The first tooth blocks 6 are uniformly arranged on the inner wall of the first sliding groove 5. One end of the connecting plate 12 away from the second tooth block 11 is provided with a control assembly. The connecting plates 12 are all slidably installed on the inner wall of the through groove 15. The through groove 15 is opened on both sides of the slider 10; through the arranged fixing assembly, after the position of the handle body 4 is adjusted, the second tooth blocks 11 can be embedded between the first tooth blocks 6, so as to fix the handle body 4.
[0030] Please refer to Figures 3-4, in the illustration, the control component includes a first spring 13 and a second connecting rope 14 disposed between the connecting plates 12. Both ends of the first spring 13 are fixedly connected to the ends of the connecting plates 12.

The first connecting rope 9 passes through the slider 10 and is embedded inside the handle main body 4. A sliding button 8 is fixedly installed at one end of the first connecting rope 9 away from the connecting plate 12. The sliding button 8 is slidably installed on the inner wall of the second chute 7. The second chute 7 is opened on one side of the handle main body 4. When it is necessary to adjust the position of the handle main body 4 through the adjusting component, the sliding button 8 can be pushed, so that the sliding button 8 controls the second tooth block 11 to disengage from between the first tooth blocks 6. At this time, the handle main body 4 and the second bracket main body 3 can move relative to each other, thereby adjusting the position of the handle main body 4 and facilitating the adjustment of the position of the handle main body 4.
[0031] Embodiment 2
[0032] Please refer to Figure 3 , on the side wall of the sliding button 8 in the illustration, protrusions are uniformly arranged; which plays an anti-slip role and facilitates the movement of the sliding button 8, thereby controlling the movement of the handle main body 4.
[0033] Please refer to Figure 4 , in the illustration, the cross-sections of the second tooth block 11 and the first tooth block 6 are both set as right-angled triangles, and the hypotenuse of the right-angled triangle is arranged on the side away from the first bracket main body 1; when the second tooth block 11 is placed between the first tooth blocks 6, at this time, the right-angled sides of the second tooth block 11 and the first tooth block 6 are mutually attached, making the force between the second tooth block 11 and the first tooth block 6 more uniform, avoiding the inclination of the force direction when the hypotenuse contacts, which may easily cause the second tooth block 11 to contract, resulting in unstable fixation of the handle main body 4 and the patient needing to frequently adjust it, which is rather troublesome. This improves the stability of the device.
[0034] Working principle: When the device needs to be trained, first push the sliding button 8, so that the sliding button 8 drives the first connecting rope 9 to move. The movement of the first connecting rope 9 drives the second connecting rope 14 to move, making the second connecting rope 14 pull the connecting plate 12 to move towards the middle. The movement of the connecting plate 12 drives the second tooth block 11 to disengage from between the first tooth blocks 6, enabling the slider 10 to slide on the inner wall of the first chute 5. Then hold the handle main body 4 and squeeze the handle main body 4, so that the handle main body 4 squeezes the second spring 16 and the telescopic rod 17, making the slider 10 slide on the inner wall of the first chute 5. Then adjust the position of the handle main body 4, release the sliding button 8, and under the action of the first spring 13, the second tooth block 11 is embedded between the first tooth blocks 6, thereby fixing the handle main body 4. Adjust the position of the handle main body 4 and then start training.
[0035] When used by different users, the sliding button 8 can be pushed to separate the second tooth block 11 from the first tooth block 6. Then, under the action of the second spring 16 and the telescopic rod 17, the handle main body 4 will be pushed to move away from the first bracket main body 1. Then the user holds the handle main body 4 and adjusts the position of the handle main body 4 again.
[0036] Please refer to Figures 1-3 , there are convex blocks on the side wall of the handle main body 4 in the figure that cooperate with the fingers; it can make the placement of the fingers more comfortable when the patient is training, improving the comfort of the patient during training.
[0037] It should be understood that those of ordinary skill in the art can make improvements or changes according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present utility model.
