Description

Technical Field

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

[0002] Nowadays, people are paying more and more attention to their health and use various fitness equipment to exercise different parts of their bodies. For example, arm strength trainers are used to exercise the user's arm muscles and can also help users exercise their wrist strength.

[0003] Commercially available arm exercisers consist of an arm spring and a grip. Users can grip the grip to overcome the resistance of the arm spring, thereby achieving the effect of exercising arm muscles. However, the grip is fixed to the arm exerciser and the distance between the grip and the arm spring cannot be adjusted, making the resistance of the arm exerciser constant for the user. It is impossible to adjust the resistance of the arm exerciser according to the different physical conditions of the exercisers. Therefore, there is an urgent need for an arm exerciser that can adjust the distance between the grip and the arm spring. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes an adjustable arm strength trainer, which solves the issue that traditional arm strength trainers cannot adjust the distance between the handle and the arm strength spring.

[0005] The technical solution adopted by this utility model is as follows: an adjustable arm strength trainer, including a torsion member and connecting rods. There are two connecting rods, each connected to one end of the torsion member. A handle is slidably connected to the connecting rod, and a lever is rotatably connected to the handle. The handle and the lever are connected to an elastic device. The lever includes a mounting post, and the handle has a clearance opening for the mounting post to pass through. A mounting groove is provided on the connecting rod, and the mounting post extends into the mounting groove. The extension direction of the mounting groove is the same as the length direction of the connecting rod. A positioning groove is also provided in the mounting groove, with at least two positioning grooves spaced apart. Each positioning groove is located on one inner wall of the mounting groove. The elastic device drives the mounting post into the positioning groove, allowing the mounting post to selectively engage within the positioning groove. When the lever is driven to a position where the mounting post and the positioning groove are completely separated, the mounting post is located within the mounting groove, and the handle can slide along the length direction of the connecting rod.

[0006] Through the above technical solution, the user drives the actuating component to rotate on the handle, causing the mounting post to move within the positioning groove, and causing the elastic device to undergo elastic deformation. This continues until the actuating component rotates to a position where the mounting post and positioning groove are completely separated, with the mounting post located within the mounting groove. The user can then drive the handle to slide along the length of the connecting rod until the mounting post moves to the opening of another positioning groove. The user then removes the force applied to the actuating component, and the elastic deformation of the elastic device begins to recover. Under the action of the rebound force, the actuating component rotates on the handle, and the mounting post moves into the positioning groove until the elastic device returns to its initial state, at which point the mounting post is engaged in the positioning groove. The user then adjusts the distance between the handle and the actuating component, thus completing the resistance adjustment of the arm exerciser. This utility model of the arm exerciser changes the resistance by engaging the mounting post of the actuating component with positioning grooves at different positions on the connecting rod, thereby adapting to various intensity training needs. This greatly expands the user base of the arm exerciser and enhances the user experience.

[0007] Furthermore, the elastic device is a torsion spring, the connecting rod passes through the torsion spring, the inner wall of the actuating member is provided with a limiting protrusion, the inner wall of the grip is provided with a corresponding limiting plate, one end of the torsion spring abuts against the limiting protrusion, the other end of the torsion spring abuts against the limiting plate, and the mounting post and the torsion spring are separated from each other.

[0008] With the above technical solution, the user rotates the toggle switch, driving the mounting post to move within the positioning groove, and causing the limiting protrusion to compress the torsion spring, resulting in elastic deformation of the torsion spring. This continues until the toggle switch rotates to a position where the mounting post and positioning groove are completely separated, with the mounting post located within the mounting groove. The user can then drive the handle to slide along the length of the connecting rod, moving the mounting post within the mounting groove to the opening of another positioning groove. When the user removes the force applied to the toggle switch, the elastic deformation of the torsion spring begins to recover and pushes the limiting protrusion, causing the toggle switch to rotate on the handle under the action of the rebound force. The mounting post moves into the positioning groove until the torsion spring returns to its initial state, at which point the mounting post engages within the positioning groove, thus completing the adjustment of the distance between the handle and the toggle switch.

[0009] Furthermore, the actuating element is generally ring-shaped.

[0010] Through the above technical solution, the annular actuating element makes the connection between the actuating element and the grip very stable, preventing the actuating element from coming off when rotating on the grip.

[0011] Furthermore, the elastic device includes an arc-shaped column and an elastic element. The elastic element is sleeved on the arc-shaped column. One end of the arc-shaped column is provided with a column head, which abuts against the mounting column. An mounting piece is provided inside the handle, and an mounting notch is provided on the mounting piece. The other end of the arc-shaped column passes through the mounting notch. One end of the elastic element abuts against the column head, and the other end of the elastic element abuts against the mounting piece.

[0012] With the above technical solution, the user rotates the actuating component, driving the mounting post to move within the positioning groove. The mounting post then presses against the head of the curved post, causing the curved post to move within the handle. The elastic element undergoes elastic deformation due to the pressure from the post head. This continues until the actuating component rotates to a position where the mounting post and positioning groove are completely separated. The mounting post is then positioned within the mounting groove. The user can then slide the handle along the length of the connecting rod, moving the mounting post within the mounting groove to the opening of another positioning groove. When the user removes the force applied to the actuating component, the elastic deformation of the elastic element begins to recover, pushing the post head. The head of the curved post, under the action of elastic force, pushes the mounting post, causing the actuating component to rotate on the handle under the action of rebound force. The mounting post moves into the positioning groove until the curved post and elastic element return to their initial state, at which point the mounting post engages within the positioning groove, thus completing the adjustment of the distance between the handle and the actuating component.

[0013] Furthermore, the actuating element is generally sheet-shaped.

[0014] Through the above technical solution, the plate-shaped actuating element makes the rotation of the actuating element on the handle smoother. Users only need to use a small amount of force to drive the actuating element to rotate, making it very convenient to use.

[0015] Furthermore, the positioning slots are arranged sequentially and at equal intervals on the connecting rod.

[0016] Through the above technical solution, the positioning slots arranged sequentially and at equal intervals ensure that the resistance changes very evenly when the handle slides on the connecting rod to adjust the resistance. This prevents the resistance from fluctuating during adjustment, allowing users to control the resistance changes when adjusting the intensity of the arm strength trainer, making it more adaptable to different training needs.

[0017] Furthermore, the connecting rod is also provided with a load indicator, which is correspondingly provided with the positioning groove.

[0018] With the above technical solution, users can quickly adjust the exercise intensity of the arm exerciser according to the load markings corresponding to each positioning slot, so that users can quickly find the exercise intensity that suits them and make it more convenient to exercise with the arm exerciser.

[0019] Furthermore, the actuating element is provided with a pressing protrusion, and the side of the pressing protrusion is provided with a rotation mark.

[0020] With the above technical solution, users can apply force to the pressing protrusion to quickly drive the toggle to rotate, which is very convenient to use. The rotation indicator allows users to distinguish the rotation direction of the toggle in time, avoiding doing useless work due to incorrect force application. Attached Figure Description

[0026] See Figures 1-11As shown, an adjustable arm exerciser includes a torsion member 1 and connecting rods 2. There are two connecting rods 2, which are respectively connected to the two ends of the torsion member 1. A handle 3 is slidably connected to the connecting rod 2, and a lever 4 is rotatably connected to the handle 3. The handle 3 and the lever 4 are connected to an elastic device. The lever 4 includes a mounting post 5. The handle 3 is provided with a clearance opening 6 for the mounting post 5 to pass through. The connecting rod 2 has a mounting groove 7, and the mounting post 5 extends into the mounting groove 7. The extension direction of the mounting groove 7 is the same as the length direction of the connecting rod 2. The mounting groove 7 is also provided with a positioning groove 8. There are at least two positioning grooves 8, which are spaced apart. The positioning grooves 8 are all located on one side of the inner wall of the mounting groove 7. The elastic device is used to drive the mounting post 5 into the positioning groove 8. The mounting post 5 can selectively engage in the positioning groove 8. When the lever 4 is driven to the position where the mounting post 5 and the positioning groove 8 are completely separated, the mounting post 5 is located in the mounting groove 7, and the handle 3 can slide along the length direction of the connecting rod 2. The user drives the actuating element 4 to rotate on the handle 3, causing the mounting post 5 to move within the positioning groove 8 and the elastic device to undergo elastic deformation. This continues until the actuating element 4 rotates to a position where the mounting post 5 and the positioning groove 8 are completely separated, with the mounting post 5 located within the mounting groove 7. The user can then drive the handle 3 to slide along the length of the connecting rod 2 until the mounting post 5 moves within the mounting groove 7 to the opening of another positioning groove 8. The user then removes the force applied to the actuating element 4, and the elastic deformation of the elastic device begins to recover. Under the action of the rebound force, the actuating element 4 rotates on the handle 3, and the mounting post 5 moves into the positioning groove 8 until the elastic device returns to its initial state, at which point the mounting post 5 is engaged within the positioning groove 8. The user then adjusts the distance between the handle 3 and the torsion element 1, thus completing the resistance adjustment of the arm exerciser. This utility model of the arm exerciser changes the resistance by engaging the mounting post 5 of the actuating element 4 with different positions of the positioning grooves 8 on the connecting rod 2, thereby adapting to various intensity training needs. This greatly expands the user base of the arm exerciser and enhances the user experience.

[0027] The preferred torsion element 1 is a torsion spring.

[0028] See Figures 1-4As shown, the elastic device is a torsion spring 9, the connecting rod 2 passes through the torsion spring 9, the inner wall of the actuating member 4 is provided with a limiting protrusion 10, the inner wall of the grip 3 is provided with a corresponding limiting piece 11, one end of the torsion spring 9 abuts against the limiting protrusion 10, the other end of the torsion spring 9 abuts against the limiting piece 11, and the mounting post 5 and the torsion spring 9 are separated from each other. The user rotates the actuator 4, driving the mounting post 5 to move within the positioning groove 8, and causing the limiting protrusion 10 to compress the torsion spring 9, resulting in elastic deformation of the torsion spring 9. When the actuator 4 rotates to the position where the mounting post 5 and the positioning groove 8 are completely separated, the mounting post 5 is located within the mounting groove 7. The user can then drive the handle 3 to slide along the length of the connecting rod 2, moving the mounting post 5 within the mounting groove 7 to the opening of another positioning groove 8. When the user removes the force applied to the actuator 4, the elastic deformation of the torsion spring 9 begins to recover and pushes the limiting protrusion 10, causing the actuator 4 to rotate on the handle 3 under the action of the rebound force. The mounting post 5 moves into the positioning groove 8 until the torsion spring 9 returns to its initial state, at which point the mounting post 5 is engaged within the positioning groove 8, thus completing the adjustment of the distance between the handle 3 and the actuator 1.

[0029] See Figure 3 As shown, the actuating element 4 is ring-shaped. The ring shape of the actuating element 4 makes the connection between the actuating element 4 and the grip 3 very stable, preventing the actuating element 4 from coming off when rotating on the grip 3.

[0030] See Figures 5-9 As shown, the elastic device includes an arc-shaped column 12 and an elastic element 13. The elastic element 13 is sleeved on the arc-shaped column 12. One end of the arc-shaped column 12 is provided with a column head 14, which abuts against the mounting column 5. A mounting piece 15 is provided inside the handle 3, and a mounting notch 16 is provided on the mounting piece 15. The other end of the arc-shaped column 12 passes through the mounting notch 16. One end of the elastic element 13 abuts against the column head 14, and the other end of the elastic element 13 abuts against the mounting piece 15. When the user rotates the actuating component 4, it drives the mounting column 5 to move within the positioning groove 8, causing the mounting column 5 to press against the column head 14 of the arc-shaped column 12. This causes the arc-shaped column 12 to move within the handle 3. The elastic element 13 undergoes elastic deformation due to the pressure from the column head 14. When the actuating component 4 rotates to the position where the mounting column 5 and the positioning groove 8 are completely separated, the mounting column 5 is located within the mounting groove 7. The user can then drive the handle 3 to slide along the length of the connecting rod 2, moving the mounting column 5 within the mounting groove 7 to another positioning groove. At the opening of the slot 8, when the user removes the force applied to the actuating element 4, the elastic deformation of the elastic element 13 begins to recover and pushes the column head 14, causing the column head 14 of the arc-shaped column 12 to push the mounting column 5 under the action of elastic force. This causes the actuating element 4 to rotate on the grip 3 under the action of rebound force, and the mounting column 5 moves into the positioning slot 8 until the arc-shaped column 12 and the elastic element 13 return to their initial state. At this point, the mounting column 5 is engaged in the positioning slot 8, thus completing the adjustment of the distance between the grip 3 and the torsion element 1.

[0031] The preferred elastic element 13 is a spring.

[0032] See Figure 7 As shown, the toggle element 4 is generally plate-shaped. The plate-shaped toggle element 4 makes the rotation of the toggle element 4 on the handle 3 smoother, and the user only needs to use a small amount of force to drive the toggle element 4 to rotate, which is very convenient to use.

[0033] See Figure 10 As shown, the positioning grooves 8 are arranged sequentially and equidistantly on the connecting rod 2. The sequentially arranged and equidistantly positioned positioning grooves 8 ensure that the resistance changes very evenly when the handle 3 slides on the connecting rod 2 to adjust the resistance, and there will be no problem of the resistance fluctuating during the sliding adjustment. The change in resistance can be controlled when the user adjusts the exercise intensity of the arm strength trainer, making it more adaptable to different exercise needs.

[0034] See Figure 1 , 2 As shown in Figures 5, 6, and 10, the connecting rod 2 is also equipped with a load indicator 17, which corresponds to the positioning slot 8. Users can quickly adjust the exercise intensity of the arm exerciser according to the load indicator 17 corresponding to each positioning slot 8, allowing users to quickly find a suitable exercise intensity and making it more convenient to exercise with the arm exerciser.

[0035] Preferably, there are five positioning slots 8 on the connecting rod 2. The five positioning slots 8 are arranged sequentially and equidistantly along the length of the connecting rod 2. There are five load marks 17 on the connecting rod 2. The five load marks 17 correspond one-to-one with the five positioning slots 8. The resistance of the five load marks 17 decreases sequentially along the length of the connecting rod 2.

[0036] See Figure 1 , 2 As shown in Figures 3, 5, 6, and 7, the actuating element 4 is provided with a pressing protrusion 18, and a rotation indicator 19 is provided on the side of the pressing protrusion 18. The user can apply force to the pressing protrusion 18 to quickly drive the actuating element 4 to rotate, which is very convenient to use. The rotation indicator 19 allows the user to distinguish the rotation direction of the actuating element 4 in time, avoiding doing useless work due to incorrect force application.

[0037] In use, the user rotates the actuating element 4, driving the mounting post 5 to move within the positioning groove 8, and causing the limiting protrusion 10 to compress the torsion spring 9, resulting in elastic deformation of the torsion spring 9. When the actuating element 4 rotates to the position where the mounting post 5 and the positioning groove 8 are completely separated, the mounting post 5 is located within the mounting groove 7. The user can then drive the handle 3 to slide along the length of the connecting rod 2, moving the mounting post 5 within the mounting groove 7 to the opening of another positioning groove 8. When the user removes the force applied to the actuating element 4, the elastic deformation of the torsion spring 9 begins to recover and pushes the limiting protrusion 10, causing the actuating element 4 to rotate on the handle 3 under the action of the rebound force. The mounting post 5 moves into the positioning groove 8 until the torsion spring 9 returns to its initial state, at which point the mounting post 5 is engaged within the positioning groove 8. Alternatively, the user rotates the actuating element 4, driving the mounting post 5 to move within the positioning groove 8, and causing the mounting post 5 to compress the head 14 of the arc-shaped post 12, causing the arc-shaped post 12 to engage within the handle. During the movement of the lever 3, the elastic element 13 is compressed by the column head 14 and undergoes elastic deformation until the lever 4 rotates to the position where the mounting column 5 and the positioning groove 8 are completely separated. The mounting column 5 is located in the mounting groove 7. The user can drive the handle 3 to slide along the length of the connecting rod 2, moving the mounting column 5 in the mounting groove 7 to the opening of another positioning groove 8. When the user removes the force applied to the lever 4, the elastic deformation of the elastic element 13 begins to recover and pushes the column head 14, allowing the column head 14 of the arc column 12 to push the mounting column 5 under the action of elastic force. This causes the lever 4 to rotate on the handle 3 under the action of rebound force, and the mounting column 5 moves into the positioning groove 8 until the arc column 12 and the elastic element 13 return to their initial state. The mounting column 5 is then engaged in the positioning groove 8. The user can change the resistance of the arm strength trainer by engaging the mounting column 5 of the lever 4 with the positioning grooves 8 at different positions on the connecting rod 2, thereby adapting to various intensity training needs.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
