[0031] In the description of the present disclosure, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "connect", "connected", "install" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0032] As shown in Figures 1 to 2 The present disclosure provides a grip strength trainer, comprising a main frame 10 and a tension component 20, the main frame 10 is provided with a containing space 11, the containing space 11 is used to accommodate the tension component 20, the tension component 20 comprises a plurality of tension pieces 21, the plurality of tension pieces 21 are arranged along the transverse direction of the main frame 10 and are slidingly connected to the main frame 10.

[0033] Through the above technical solution, through the plurality of tension pieces 21 arranged, the patient can pull different tension pieces 21 at the same time or separately during use, that is, the purpose of adjusting the training degree of different fingers can be achieved by increasing or decreasing the number of tension pieces 21, and since the plurality of tension pieces 21 can be slidingly connected to the main frame 10, the patient can adjust the distance between the tension pieces 21 according to the size of the palm before use. The grip strength trainer of the present disclosure not only provides effective hand muscle exercise, but also has high flexibility and adjustability, which is suitable for personalized training of users with different needs.

[0034] In addition, the containing space 11 on the main frame 10 is designed to store the tension component 20, so that the whole device is more compact, and is convenient for the patient to carry and store.

[0035] Optionally, the main frame 10 can be made of metal or high-strength plastic, which ensures the stability and durability of the grip strength trainer. As an embodiment, as shown in Figure 1 The main frame 10 can comprise a support rod 12 and a guide rail plate 13, the support rod 12 and the guide rail plate 13 jointly enclose the containing space 11, the guide rail plate 13 is formed with a sliding groove 14 extending along the transverse direction, and the plurality of tension pieces 21 are slidingly connected to the sliding groove 14.

[0036] Since the sliding groove 14 extending along the transverse direction is formed on the guide rail plate 13, the movement direction of the tension piece 21 can be guided and limited, that is, the guide rail plate 13 arranged can provide a guiding effect for adjusting the distance between the tension pieces 21.

[0037] Among them, the support rod 12 provides the necessary structural stability and strength, ensuring the safety of the grip strength trainer under high-strength use.

[0038] In order to slide the tension member 21 on the sliding groove 14, as an embodiment, as shown in Figure 1 the tension member 21 can include a tension member body 211, a limiting protrusion 212 and a fastening nut 213, the tension member body 211 has a connecting section 2111 penetrating the sliding groove 14, the limiting protrusion 212 protrudes outwardly from the connecting section 2111 along the radial direction, the connecting section 2111 is formed with external threads, and the fastening nut 213 is threadedly connected on the connecting section 2111 so that the bottom surface of the limiting protrusion 212 can abut against the top surface of the rail plate 13, wherein the rail plate 13 is located between the limiting protrusion 212 and the fastening nut 213.

[0039] When it is necessary to adjust the position of the tension member body 211 on the rail plate 13, the tension member body 211 can penetrate the sliding groove 14 through the connecting section 2111 and slide back and forth on the sliding groove 14, and when it is slid to the appropriate position, the fastening nut 213 can be threadedly connected on the connecting section 2111 so that the rail plate 13 is located between the limiting protrusion 212 and the fastening nut 213, that is, the tension member body 211 can be fastened on the rail plate 13 through the fastening nut 213. In this way, by combining the threaded connection and the sliding connection, the flexible adjustment and stable fixation of the tension member 21 are realized, which not only meets the needs of personalized training, but also ensures the safety and reliability of the use of the training device. In addition, this design also simplifies the maintenance and disassembly process of the training device, which is convenient for patients to clean or replace parts.

[0040] As another embodiment, the tension member 21 can include a tension member body 211 and two fastening nuts 213, the tension member body 211 has a connecting section 2111 penetrating the sliding groove 14, the connecting section 2111 is formed with external threads, and the two fastening nuts 213 are threadedly connected on the connecting section 2111 so that the rail plate 13 is located between the two fastening nuts 213.

[0041] In this way, the position of the tension member 21 on the rail plate 13 in the longitudinal direction can be adjusted by adjusting the positions of the two fastening nuts 213 in the axial direction of the connecting section 2111, that is, by the cooperation between the two fastening nuts 213 and the connecting section 2111, the effective working length of the tension member 21 can be changed, that is, the resistance can be adjusted, which meets the training needs of different intensities.

[0042] In order to prevent the tension member 21 from slipping off the rail plate 13, optionally, the outer diameter of the limiting protrusion 212 and the outer diameter of the fastening nut 213 are both greater than the width of the sliding groove 14.

[0043] As an embodiment, as shown in Figure 1As shown, the tension member body 211 further comprises a spring 2112, a finger ring 2113, and a buffer 2114. The first end of the spring 2112 is connected to the outer peripheral wall of the finger ring 2113, and the second end of the spring 2112 is connected to one end of the connecting segment 2111 close to the limiting protrusion 212. The finger ring 2113 has a channel 2115 formed therein for the patient's finger to pass through. The buffer 2114 is located in the channel 2115 and connected to the channel 2115 wall of the channel 2115. The end of the buffer 2114 away from the channel 2115 wall of the channel 2115 is used to contact the outer peripheral surface of the finger.

[0044] Since the finger ring 2113 has a channel 2115 formed therein for the patient's finger to pass through, the patient can directly pull the tension member 21 by the finger to perform grip or finger strength training. The presence of the finger ring 2113 makes the training action more natural, simulating many scenarios in daily life that require finger strength, such as holding a pen, twisting a bottle cap, etc. Moreover, the buffer 2114 is located inside the channel 2115 of the finger ring 2113, connected to the channel 2115 wall, and extends to the center of the channel 2115 for direct contact with the outer peripheral surface of the patient's finger. The material of the buffer 2114 can be soft and elastic, such as silicone or foam, to reduce discomfort during training and improve comfort. In addition, the buffer 2114 can also help distribute pressure and prevent pressure injuries from long-term training. Such design not only improves the effectiveness of the training, but also fully considers the comfort and safety of the patient, making the grip strength trainer a professional and user-friendly rehabilitation training tool. Optionally, as shown in FIG. 12, the buffer 2114 can be a soft and elastic ring that extends along the circumference of the channel 2115. Figure 1 As shown, the buffer 2114 is an elastic ring that extends along the circumference of the channel 2115. In the natural state of the elastic ring, the inner diameter of the elastic ring is larger than the outer diameter of the finger.

[0045] Since the inner diameter of the elastic ring in the natural state is larger than the outer diameter of the finger, i.e., without external force, the elastic ring will not exert excessive pressure on the user's finger. This design can adapt to different finger sizes of users, so even people with thicker fingers or larger joints can use the device comfortably without worrying about compression or discomfort. When the patient's finger passes through the elastic ring and pulls the tension member 21, the elastic ring will be moderately compressed to fit the contour of the finger, reducing the risk of friction or cuts caused by hard edges, ensuring comfort during training.

[0046] In addition, since the elastic ring can extend along the circumference of the channel 2115, it will form a continuous support surface around the finger, avoiding excessive local pressure and reducing the risk of hot spots or pain points during training.

[0047] The material of the elastic ring is generally chosen to be soft and elastic, such as silicone or rubber, so as to ensure both comfort and that it will not irritate the skin.

[0048] As one implementation method, such as Figure 1 As shown, the support rod 12 includes two parallel support rods 121 and a stop rod 122. The stop rod 122 includes a first section 1221, a middle section 1222, and a second section 1223. The first section 1221 and the second section 1223 are respectively connected to the two ends of the middle section 1222 and extend in directions away from each other. The first section 1221 and the second section 1223 are respectively used to connect to the upper ends of the two support rods 121. The middle section 1222 is constructed as an arc segment, and the center of the arc segment is far away from the receiving space 11.

[0049] Setting the middle segment 1222 as an arc segment has the following advantages:

[0050] (1) The shape of the arc-shaped middle section 1222 is more in line with the ergonomic principle. In particular, when the user uses the grip strength trainer, the arc structure can better adapt to the natural curvature of the hand and improve the comfort when holding it.

[0051] (2) The arc-shaped structure can provide stronger bending resistance in mechanics. Even under the action of lateral force, it can maintain the stability of the structure and reduce the risk of deformation.

[0052] (3) The arc design often gives people a sense of visual beauty. At the same time, the design of the arc center being far away from the storage space 11 means that the lever will not occupy too much internal space, which is conducive to the compact design of the equipment and makes it easy to carry and store.

[0053] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0055] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
