Description

Technical Field

[0001] This utility model relates to the field of grip strength meter technology, and in particular to a grip strength meter structure. Background Technology

[0002] Grip dynamometers, as tools for measuring and training hand strength, are widely used in medical rehabilitation, sports training, and daily fitness. Currently, grip dynamometers commonly found on the market are mainly divided into two categories: digital display testing grip dynamometers and elastic training grip dynamometers.

[0003] Digital grip strength testers, with their ability to measure and display grip strength values ​​in real time, have gained popularity among those who need precise grip strength data. They typically have built-in sensors and a display screen. When a user grips the grip strength tester and applies force, the sensor detects the magnitude of the force, processes it through relevant circuitry, and displays the specific value clearly on the screen. This function allows doctors to accurately assess a patient's hand recovery in medical diagnosis, and coaches to develop more scientific training plans based on athletes' grip strength data in sports training.

[0004] Elastic grip strength testers, on the other hand, are purely mechanical in structure and are designed primarily to meet people's daily needs for hand strength training. They are generally made of elastic materials, such as springs or rubber, and users exercise their hand muscles through repeated gripping. These grip strength testers are simple in structure, low in cost, and easy to carry, making them suitable for exercise anytime in daily life.

[0005] However, both existing grip strength meters have a significant structural flaw: they cannot be freely disassembled and reassembled. This forces consumers to purchase two different grip strength meters to meet their diverse needs: one for accurate grip strength testing and another for daily exercise. This not only increases the financial burden on consumers but also occupies more storage space, causing inconvenience in carrying and using them, thus reducing their practicality. Therefore, improving the structure of existing grip strength meters to combine testing and exercise functions and meet the diverse needs of consumers has become an urgent problem to be solved in this field. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a detachable and interchangeable grip strength meter structure.

[0007] A grip strength meter structure designed for this purpose includes a fixed element and a movable element movably disposed relative to the fixed element; the fixed element and the movable element are connected to an elastic element or a tensile testing element; one end of the elastic element is detachably connected to the fixed element and the other end is detachably connected to the movable element; one end of the tensile testing element is detachably connected to the fixed element and the other end is detachably connected to the movable element.

[0008] Preferably, the movable element is provided with a plurality of first connecting hooks, and the elastic element or tensile testing element is hooked and fixed to the first connecting hooks.

[0009] Preferably, the fixing element is provided with a plurality of second connecting hooks, and the elastic element is hooked and fixed with the second connecting hooks.

[0010] Preferably, one end of the tensile testing element connected to the fixing element is detachably connected to an adjusting screw, and the fixing element is rotatably provided with an adjusting nut; the adjusting screw and the adjusting nut are threadedly connected.

[0011] Preferably, the tensile testing element is threadedly connected to the adjusting screw.

[0012] Preferably, the fixing element is provided with an interconnected mounting groove and a through groove; the adjusting nut is rotatably disposed in the mounting groove and at least partially located outside the mounting groove; the adjusting screw passes through the through groove.

[0013] Preferably, the elastic element is a tension spring.

[0014] Preferably, the fixed element is provided with a travel limiting groove, and the moving element is provided with a limiting member, which is inserted into the travel limiting groove.

[0015] Preferably, the movable element includes two plates that are attached to the front and rear walls of the fixed element, and the limiting member passes through the travel limiting groove and is connected and fixed to the two plates.

[0016] Preferably, the fixing element is provided with an abutment, and the moving element is provided with a gripping element; an installation space is provided between the fixing element and the moving element, and the elastic element or tensile testing element is disposed in the installation space; the gripping element is disposed between the abutment and the installation space.

[0017] Compared with the prior art, this utility model's grip strength meter structure achieves significant technical advantages and practical value by incorporating a detachable elastic element and a tensile testing element. Specific beneficial effects are as follows:

[0018] First, it achieves flexible switching and integration of functions. Users can detachably connect the elastic element or tensile testing element between the fixed and moving elements according to their actual needs: when connected to the elastic element, the hand grip strength meter can be used as a purely mechanical exercise tool to meet daily hand muscle training needs; when replaced with the tensile testing element, it can switch to digital display testing mode to accurately obtain grip strength values. It can take into account both exercise and testing functions without the need to purchase two separate devices, greatly improving the product's versatility.

[0019] Secondly, it reduces user costs and space requirements. Compared to the traditional solution that requires purchasing two different grip strength meters, this modular design reduces the number of devices, not only lowering consumer spending but also saving storage space. It is particularly suitable for efficient use in homes, gyms, and other similar settings, enhancing the product's economy and convenience.

[0020] Finally, the product's adaptability and durability are enhanced. The detachable connection method allows individual components (such as when elastic elements age or tensile testing elements fail) to be replaced independently, eliminating the need for complete equipment scrapping and extending the overall product lifespan. It also facilitates future functional upgrades (such as replacing elastic elements with different elastic coefficients or higher-precision testing elements), thereby improving the product's sustainability and market competitiveness.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0034] See Figures 1-5 A grip strength meter structure includes a fixed element 10 and a movable element 20 movably disposed relative to the fixed element 10; the fixed element 10 and the movable element 20 are connected to an elastic element 30 or a tensile testing element 50; one end of the elastic element 30 is detachably connected to the fixed element 10 and the other end is detachably connected to the movable element 20; one end of the tensile testing element 50 is detachably connected to the fixed element 10 and the other end is detachably connected to the movable element 20.

[0035] The working principle of this grip strength meter is based on the detachable connection characteristics of modular components. By switching between different functional components, grip strength training or testing functions can be achieved, as detailed below:

[0036] When a user needs to perform daily hand strength exercises, the two ends of the elastic element 30 can be detachably connected to the fixed element 10 and the movable element 20, respectively. At this time, the user grips the fixed element 10 and the movable element 20 and applies gripping force. The movable element 20 will move relative to the fixed element 10, causing the elastic element 30 to deform. The reaction force generated by the deformation of the elastic element 30 will act on the user's hand. By overcoming this reaction force and repeatedly gripping, the user can achieve the purpose of exercising hand muscles.

[0037] When a user needs to test their grip strength, they simply remove the elastic element 30 and replace it with the tensile testing element 50. Similarly, the two ends of the tensile testing element 50 are detachably connected to the fixed element 10 and the movable element 20, respectively. When the user grips the fixed element 10 and the movable element 20 and applies grip force, the movable element 20 moves relative to the fixed element 10, generating a pulling force on the tensile testing element 50. The tensile testing element 50 can sense the magnitude of this pulling force and, through its own sensing and processing mechanism, accurately display the corresponding grip strength value, thus completing the grip strength test process.

[0038] This simple component replacement allows for flexible switching between exercise and testing functions, meeting users' needs in different scenarios.

[0039] The tensile testing element 50 can be a mature tensile sensing and display device in the existing technology, such as:

[0040] Digital display tension sensor: This type of device has built-in strain gauges and other sensing components that can convert external force into electrical signals. With the help of a display screen, it can output the tension value in real time. It is commonly found in small electronic force measuring devices. The connection structure at both ends can be adapted to the detachable interface of the fixed element 10 and the moving element 20 to achieve accurate quantification of grip force.

[0041] Mechanical force gauges, such as Bourdon tube force gauges, use the deformation of an internal spring to drive the pointer to rotate, displaying the magnitude of the pulling force on a dial. The hooks or connecting ends at both ends can form detachable connections with fixed or moving components. They can complete grip strength tests without electricity, making them suitable for scenarios with high portability requirements.

[0042] See Figure 1 and Figure 4 The movable element 20 is provided with a plurality of first connecting hooks 210, which can be quickly fixed to the elastic element 30 or the tensile testing element 50 by hooking. This design not only ensures the stability of the connection and prevents the element from falling off during use, but also simplifies the disassembly and assembly operation, allowing users to easily switch between different elements, thus improving the convenience and flexibility of using the grip strength meter.

[0043] See Figure 4 The tensile testing element 50 is connected to a connecting part 510, which is hooked and fixed to the first connecting hook 210.

[0044] See Figure 1 The fixing element 10 is provided with a plurality of second connecting hooks 110, and the elastic element 30 is hooked and fixed with the second connecting hooks 110.

[0045] Specifically, the elastic element 30 is a tension spring. The two ends of the tension spring are connected to the first connecting hook 210 and the second connecting hook 110, respectively.

[0046] Specifically, in this invention, the number of the first connecting hook 210 and the second connecting hook 110 can be set according to different tensile force requirements. By increasing the number of the first connecting hook 210 and the second connecting hook 110, the number of elastic elements 30 can be increased, thereby switching between different tensile exercise requirements.

[0047] See Figure 4 and Figure 5The tensile testing element 50 is detachably connected to the fixed element 10 at one end, with an adjusting screw 530 attached. The fixed element 10 is rotatably fitted with an adjusting nut 520. The adjusting screw 530 and the adjusting nut 520 are threadedly connected. This design of the adjusting screw 530 and the adjusting nut 520 plays multiple crucial roles in the connection between the tensile testing element 50 and the fixed element 10. Firstly, utilizing the threaded connection characteristics, rotating the adjusting nut 520 allows for precise adjustment of the length of the adjusting screw 530 extending into the fixed element 10, thereby flexibly changing the overall connection length between the tensile testing element 50 and the fixed element 10. This adjustment function can accommodate different users' hand sizes or usage habits, ensuring grip comfort during grip strength testing. It also compensates for assembly deviations caused by machining errors during installation, improving the structural adaptability. On the other hand, the threaded connection itself has self-locking properties. When adjusted to the appropriate length, the adjusting screw 530 and the adjusting nut 520 can maintain a stable connection, effectively preventing the tensile testing element 50 from loosening or shifting during the stress process, thus ensuring the accuracy of the test data and safety during use. Furthermore, this detachable threaded connection makes the disassembly and assembly of the tensile testing element 50 more convenient, facilitating later maintenance, replacement, or functional upgrades, further enhancing the practicality and flexibility of the grip strength meter structure.

[0048] Specifically, the tensile testing element 50 is threadedly connected to the adjusting screw 530. This connection can be achieved by providing a threaded sleeve 540 on the tensile testing element 50, which allows for easy assembly and disassembly of both components, facilitating the individual replacement of either the tensile testing element or the adjusting screw. Simultaneously, the threaded fit ensures a stable connection, preventing loosening during use and guaranteeing a stable and reliable testing process.

[0049] Specifically, the fixing element 10 is provided with an interconnected mounting groove 130 and a through groove 140; the adjusting nut 520 is rotatably disposed within the mounting groove 130 and at least partially located outside the mounting groove 130; the adjusting screw 530 passes through the through groove 140. The mounting groove 130 of the fixing element 10 provides rotational limiting space for the adjusting nut 520, ensuring stable rotation and limiting axial displacement, and the partially exposed design facilitates operation and adjustment; the through groove 140 provides a passage for the adjusting screw 530, ensuring smooth axial movement. The combination of the two allows the adjustment structure to operate stably within a limited space, providing reliable support for the assembly and adjustment of the tensile testing element.

[0050] See Figure 3The fixed element 10 is provided with a travel limiting groove 120, and the moving element 20 is provided with a limiting member 40, which is inserted into the travel limiting groove 120. By limiting the movement of the moving element 20 relative to the fixed element 10 through the insertion of the limiting member 40 in the travel limiting groove 120, the movement range of the moving element 20 can be precisely limited, avoiding damage to the elastic element 30 or the tensile testing element 50 due to excessive movement, while ensuring the stability and safety of the grip strength meter during use.

[0051] See Figure 3 The movable element 20 includes two plates 200 that are attached to the front and rear walls of the fixed element 10. The limiting member 40 passes through the travel limiting groove 120 and is connected and fixed to the two plates 200. This not only achieves a stable connection between the plates 200 and the fixed element 10, but also strengthens the movement guidance and range restriction of the movable element 20 relative to the fixed element 10 through the movement constraint of the limiting member 40 within the travel limiting groove 120, thereby improving the overall structure and the stability of movement.

[0052] Specifically, the limiting component 40 is a bolt, and the limiting component 40 can be connected and fixed to the two plates 200 by nuts.

[0053] See Figure 1 The fixing element 10 is provided with an abutment 60, and the moving element 20 is provided with a gripping element 70; an installation space 100 is provided between the fixing element 10 and the moving element 20, and the elastic element 30 or the tensile testing element 50 is provided in the installation space 100; the gripping element 70 is provided between the abutment 60 and the installation space 100.

[0054] When using this hand grip strength meter, its operation method and structural design are highly compatible. The specific principle is as follows:

[0055] When using the device, the user places their palm against the abutment 60 of the fixed element 10, while their fingers naturally bend to grip the handle 70 on the movable element 20. At this time, the palm and fingers act on the abutment 60 and the handle 70 respectively, forming a stable fulcrum. Since the handle 70 is located between the abutment 60 and the installation space 100, when the user applies a grip, the palm supports the fixed element 10 through the abutment 60, while the fingers move the handle 70 and the movable element 20 closer to the abutment 60.

[0056] If the installation space 100 is equipped with an elastic element 30, the movement of the moving element 20 will cause the elastic element 30 to be stretched and produce elastic deformation. Its reaction force is fed back to the fingers through the grip 70. The user can complete hand exercise by repeatedly applying force and relaxing, using the deformation force of the elastic element 30. If the installation space 100 is replaced with a tensile testing element 50, the movement of the moving element 20 will generate a tensile force on the tensile testing element 50. The tensile testing element 50 will convert the sensed force value into a readable value (such as through a digital display or pointer), thereby displaying the user's grip strength in real time and realizing the testing function.

[0057] This structural design ensures stability during the force application process by matching the positions of the abutment 60 and the grip 70. At the same time, it makes the force state of the elastic element 30 or the tensile testing element 50 more direct within the installation space 100, thereby improving the training effect and testing accuracy.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
