Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to an adjustable grip strength device. Background Technology

[0002] A hand grip strengthener is a small fitness device used to train wrist and arm strength. Many fitness enthusiasts use hand grip strengtheners when training their grip strength.

[0003] Common hand grip strengtheners consist of a pair of handles and springs that apply force in the direction that resists the approach movement of the handles. However, existing hand grip strengtheners are not adjustable and can only be used for exercises with a given grip strength, resulting in low applicability. After a period of use, the lack of adjustment means that a new hand grip strengthener must be replaced, increasing the cost of exercise. Utility Model Content

[0004] To overcome at least one of the defects described in the prior art, this utility model provides an adjustable grip strengthener to solve problems such as the inability to adjust grip strengtheners.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] An adjustable grip strengthener includes:

[0007] An elastic element, with its two ends extending to form two elastic rods at a certain angle;

[0008] The handle has two parts, which are slidably connected to two elastic rods respectively;

[0009] The adjustment mechanism is located inside the handle and connected to the end of the elastic rod;

[0010] The limiting member has long grooves at both ends. The two elastic rods pass through the long grooves at both ends of the limiting member, so that the limiting member is located between the elastic member and the handle, preventing the angle between the two elastic rods from being too large.

[0011] The above solution effectively limits the maximum extension angle of the elastic rod by setting a limiting component, making it easier for users to use and improving the safety of the hand gripper. The adjustment mechanism allows the hand gripper to be adjusted according to the grip strength level of different users, making it suitable for a wide range of people from beginners to professional trainers.

[0012] Furthermore, the adjustment mechanism includes an adjustment cylinder, a first spring, and a movable cylinder. The upper end of the adjustment cylinder is open, and the adjustment cylinder is rotatably connected to the handle. The movable cylinder is fixedly connected to the end of the elastic rod and located inside the adjustment cylinder. The inner side of the adjustment cylinder is threaded, and the outer side of the movable cylinder is threaded. The adjustment cylinder and the movable cylinder are threadedly connected. The first spring is sleeved on the elastic rod and located inside the adjustment cylinder. One end of the first spring abuts against one end inside the handle, and the other end is located inside the movable cylinder and abuts against the bottom of the movable cylinder.

[0013] Through the above further scheme, rotating the adjusting cylinder can move the moving cylinder upward. While compressing the spring, the elastic rod gradually extends outward from the handle, thereby adjusting the distance between the handle and the elastic rod. According to the lever principle in mechanics, the greater the distance, the longer the lever, and the less gripping force is required to tighten the handle; the smaller the distance, the shorter the lever, and the greater the gripping force required to tighten the handle.

[0014] Furthermore, the handle and the elastic rod are connected at opposite ends with a through hole, and the lower end of the adjusting cylinder is provided with an adjusting rod that passes through the through hole to the outside.

[0015] The above-mentioned further solution allows for the adjustment of the grip strength by rotating the adjustment cylinder using a rotating adjustment rod. This eliminates the need for disassembly or complex operations, improving the convenience of the adjustment process. The external adjustment rod also keeps the internal mechanical structure relatively enclosed, reducing the possibility of dust and dirt entering, keeping the inside of the device clean, and extending its service life.

[0016] Furthermore, the lower end of the adjusting rod is provided with a cross groove.

[0017] With the above-mentioned further solutions, the Phillips head slot allows users to use a standard screwdriver or similar tool to rotate the adjustment lever, making the adjustment process more precise and effortless.

[0018] Furthermore, a rubber sleeve is fitted onto the handle, and an opening is provided at the lower end of the rubber sleeve. The adjusting rod is located inside the opening, and the lower end of the adjusting rod is flush with the lower end of the rubber sleeve.

[0019] Through the above-mentioned further solutions, the rubber sleeve has good anti-slip and elasticity, which can effectively increase the friction between the handle and the palm, prevent slipping during use, reduce hand fatigue, and improve the comfort of holding. The lower end of the adjustment rod is flush with the lower end of the rubber sleeve to avoid the adjustment rod protruding too long, making the overall shape more concise and flat.

[0020] Furthermore, the adjusting rod has a handle on the outer end of the handle, and a groove is provided on the bottom inner end of the rubber sleeve, with the handle rotatably connected to the groove.

[0021] With the above-mentioned further solution, the rubber sleeve can be removed, and the user can directly rotate the adjustment lever by hand through the handle without the need for additional tools. This greatly improves the convenience of adjusting the resistance of the grip strengthener. When the rubber sleeve is on, the handle can be hidden, which increases the overall aesthetics of the product.

[0022] Furthermore, each of the two elastic rods is provided with two symmetrical flat grooves, and the end of the handle connected to the elastic rod is provided with a sliding hole. The sliding hole is provided with two symmetrical limiting platforms, and the limiting platforms are slidably connected to the flat grooves.

[0023] Through the above-mentioned further solutions, the design of the flat groove and the limiting platform provides a precise guiding mechanism, ensuring that the handle cannot rotate or deviate while sliding on the elastic rod, thereby enhancing the stability and reliability during use and adjustment.

[0024] Furthermore, it also includes a locking mechanism, of which there are two, each of which is respectively mounted on an elastic rod and located between the elastic member and the limiting member. The elastic rod is provided with a number of evenly arranged slots, which cooperate with the locking mechanism.

[0025] Through the above-mentioned further solutions, the locking mechanism can block the limiting component, preventing the limiting component from getting too close to the elastic component, which would cause the two elastic rods to unfold at too large an angle, affecting the user's use.

[0026] Furthermore, the locking mechanism includes a housing, a second spring, a locking member, and a pressing platform. The housing is hollow inside, with an opening on one side. The locking member is slidably connected inside the housing, and one side of the locking member is fixedly connected to the pressing platform via two connecting plates. The pressing platform passes through the opening to the outside. The locking member has a locking platform on the side facing the connecting plates that mates with a locking groove. The second spring is located inside the housing, with one end fixedly installed at the bottom of the housing and the other end fixedly installed on the side of the locking member away from the connecting plates. The housing has a through groove in the middle, and the elastic rod passes through the through groove and the two connecting plates.

[0027] Through the above-mentioned further solution, by cooperating the locking platform on the locking member with the locking groove on the elastic rod, it can be ensured that the locking mechanism can be locked in the preset position, and the limiting member is blocked in the appropriate position. When adjusting, press the button to make the locking platform disengage from the current locking groove, so that the opening angle of the gripper can be freely adjusted. After releasing the button, the second spring will automatically push the locking member back into position and relock it into the nearest locking groove.

[0028] In summary, the adjustable grip strength device provided by this utility model has the following technical effects:

[0029] 1. The adjustable mechanism allows the hand gripper to be adjusted according to the grip strength level of different users, making it suitable for a wide range of people from beginners to professional trainers.

[0030] 2. The limiting component, in conjunction with the locking mechanism, blocks the limiting component at an appropriate position, preventing it from getting too close to the elastic component and causing the two elastic rods to open at an excessive angle, thus affecting user operation.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0044] Example:

[0045] refer to Figure 1 As shown, an adjustable hand gripper includes an elastic element 1, which is a coil spring. Its two ends extend to form two elastic rods 11 with a certain angle. When the two elastic rods 11 approach each other, they exert opposite forces through the elastic element 1. Handles 2 are slidably connected to the two elastic rods 11 respectively. By gripping the handles 2, force is applied, thereby compressing the elastic element 1 and realizing the function of exercising hand muscles.

[0046] refer to Figure 1 As shown, two elastic rods 11 are provided with limiting members 4. Both ends of the limiting members 4 are provided with long grooves 41. The two elastic rods 11 pass through the long grooves 41 at both ends of the limiting members 4 respectively, so that the limiting members 4 are located in the middle between the elastic member 1 and the handle 2. By setting the limiting members 4, the maximum unfolding angle of the elastic rods 11 can be effectively limited, which is convenient for users to use and improves the safety of using the grip strengthener.

[0047] refer to Figure 1 , Figure 2 and Figure 3 As shown, an adjusting cylinder 31 is rotatably connected inside the handle 2. The upper end of the adjusting cylinder 31 is open. A movable cylinder 33 is fixedly connected to one end of the elastic rod 11 inside the handle 2 and is located inside the adjusting cylinder 31. The inner side of the adjusting cylinder 31 is threaded, and the outer side of the movable cylinder 33 is threaded. The adjusting cylinder 31 and the movable cylinder 33 are threadedly connected. A first spring 32 is sleeved on the elastic rod 11. One end of the first spring 32 abuts against one end inside the handle 2, and the other end is located inside the movable cylinder 33 and abuts against the bottom of the movable cylinder 33. Rotating the adjusting cylinder 31 can make the movable cylinder 33 move upward. While compressing the spring, the elastic rod 11 gradually extends outward from the handle 2, thereby adjusting the distance between the handle 2 and the elastic rod 1. According to the lever principle in mechanics, the greater the distance, the longer the lever, and the less gripping force is required to grip the handle 2. The smaller the distance, the shorter the lever, and the greater the gripping force required to grip the handle 2.

[0048] Among them, reference Figure 4 As shown, each of the two elastic rods 11 is provided with two symmetrical flat grooves 111. The end of the handle 2 connected to the elastic rod 11 is provided with a sliding hole 23. The sliding hole 23 is provided with two symmetrical limiting platforms 231. The limiting platforms 231 are slidably connected to the flat grooves 111. The design of the flat grooves 111 and the limiting platforms 231 provides a precise guiding mechanism to ensure that the handle 2 cannot rotate or deviate while sliding on the elastic rod 11, thereby enhancing the stability and reliability during use and adjustment.

[0049] refer to Figure 2 and Figure 5 As shown, the handle 2 and the elastic rod 11 are connected at opposite ends with a through hole 21. The lower end of the adjusting cylinder 31 is provided with an adjusting rod 311. The adjusting rod 311 passes through the through hole 21 to the outside. By rotating the adjusting rod 311, the adjusting cylinder 31 can be rotated, thereby adjusting the resistance of the grip strength. No disassembly or complicated operation is required, which improves the convenience of the adjustment process. The external adjusting rod 311 makes the internal mechanical structure relatively closed, reducing the possibility of dust and dirt entering, keeping the inside of the equipment clean, and extending its service life.

[0050] The lower end of the adjusting rod 311 is provided with a cross groove 312, which allows users to use a standard screwdriver or similar tool to rotate the adjusting rod 311, making the adjustment process more precise and effortless.

[0051] refer to Figure 2As shown, a rubber sleeve 22 is fitted on the handle 2. The lower end of the rubber sleeve 22 has an opening 221. The adjusting rod 311 is located inside the opening 221. The lower end of the adjusting rod 311 is flush with the lower end of the rubber sleeve 22. The rubber sleeve 22 has good anti-slip and elasticity, which can effectively increase the friction between the handle 2 and the palm, prevent slipping during use, reduce hand fatigue, and improve the comfort of holding. The lower end of the adjusting rod 311 is flush with the lower end of the rubber sleeve 22 to prevent the adjusting rod 311 from protruding too much, making the overall shape simpler and flatter.

[0052] Among them, reference Figure 2 As shown, the adjustment rod 311 is located on the outer end of the handle 2 and has a handle 3111. The bottom end of the rubber sleeve 22 has a groove 222. The handle 3111 is rotatably connected in the groove 222. The user can directly rotate the adjustment rod 311 by hand by simply removing the rubber sleeve 22, without the need for additional tools. This greatly improves the convenience of adjusting the resistance of the grip strengthener. When the rubber sleeve 22 is on, the handle 3111 can be hidden, which increases the overall aesthetics of the product.

[0053] refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, each of the two elastic rods 11 is equipped with a locking mechanism 5, located between the elastic member 1 and the limiting member 4. The elastic rod 11 is provided with several evenly arranged locking slots 112. The locking mechanism 5 includes a housing 51, a second spring 52, a locking member 53, and a pressing platform 54. The housing 51 is hollow inside, with an opening on one side. The locking member 53 is slidably connected inside the housing 51. One side of the locking member 53 is fixedly connected to the pressing platform 54 through two connecting plates 531. The pressing platform 54 passes through the opening to the outside. The side of the locking member 53 facing the connecting plate 531 is provided with a locking platform 532 that cooperates with the locking slots 112. The second spring 52 is located inside the housing 51. One end of the second spring 52 is fixedly installed at the bottom of the housing 51, and the other end is fixedly installed on the locking member 53 away from the connecting plate. On one side of 531, a through groove 511 is provided in the middle of the housing 51. The elastic rod 11 passes through the through groove 511 and the two connecting plates 531. The locking platform 532 on the locking member 53 cooperates with the locking groove 112 on the elastic rod 11 to ensure that the locking mechanism 5 can be locked in the preset position, blocking the limiting member 4 at an appropriate position, and preventing the limiting member 4 from getting too close to the elastic member 1, so that the two elastic rods 11 unfold too much and affect the user's use. When adjusting, press the button 54 to make the locking platform 532 disengage from the current locking groove 112, so that the unfolding angle of the grip can be freely adjusted. After releasing the button 54, the second spring 52 will automatically push the locking member 53 back to its original position and relock into the nearest locking groove 112.
