Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically a sports device for upper limb training. Background Technology

[0002] People are paying more and more attention to their health, and upper body training is also very important. Sports equipment is an important tool for exercise, fitness and rehabilitation. Using sports equipment can help people train their upper body, strengthen their strength, increase muscle size, shape or change their muscle shape, and improve their physical fitness. However, when using existing upper body training equipment, it is cumbersome to add weights when it is necessary to adjust the training intensity, and it is not possible to quickly switch the required weight and intensity.

[0003] For example, the patent with authorization announcement number CN222218548U describes a sports equipment training device for upper limb strength training, including a base frame, a sliding frame, and a counterweight frame. It can move smoothly upward between two guide frames via a sliding rod. The upward movement of the sliding rod will drive the two counterweight frames containing counterweights to move downward, allowing the trainee to perform upper limb training more smoothly, thereby achieving the purpose of training the upper limbs. However, during the training process, when it is necessary to change the required weight and intensity, it is necessary to add or remove counterweights, which cannot quickly switch the required weight and intensity, reducing the practicality of the device.

[0004] Based on this, a sports device for upper limb training is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, a sports device for upper limb training includes a support frame 1, a support plate 11 fixedly connected to the bottom end of the support frame 1, guide rails 12 symmetrically fixedly connected to the inner side wall of the support frame 1, a tensioning component 2 provided on the outer wall of the guide rails 12, a counterweight component 3 provided on the top end of the support plate 11, and an adjustment component 4 provided on the inner wall of the support plate 11.

[0025] In this embodiment, the counterweight component 3 can be adjusted by adjusting component 4, so that the force required for the pulling component 2 to pull the counterweight component 3 changes, thereby facilitating quick adjustment of the weight and force required for training.

[0026] In an optional embodiment, such as Figure 2 and Figure 3As shown, the traction assembly 2 includes a pull rod 21, with a fixed rod 22 fixedly connected to the outer wall of the pull rod 21. Guide sliders 23 are fixedly connected to both ends of the fixed rod 22, and the guide sliders 23 slide in cooperation with the guide rail 12. Traction ropes 24 are symmetrically fixedly connected to the top of the fixed rod 22. The outer wall of the traction rope 24 is sequentially connected to a first guide wheel 25 and a second guide wheel 26. The tops of the first guide wheel 25 and the second guide wheel 26 are fixedly connected to the bottom of the support frame 1. By pulling the pull rod 21, the fixed rod 22 is driven to move downward synchronously, causing the fixed rod 22 to drive the guide sliders 23 to slide on the outer wall of the guide rail 12. At the same time, the fixed rod 22 drives the traction rope 24 to move, causing the traction rope 24 to drive the counterweight assembly 3 to move upward, thereby conducting training. One or more pairs of traction ropes 24, first guide wheels 25 and second guide wheels 26 can be added as needed.

[0027] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the counterweight assembly 3 includes a mounting frame 31. The top of the mounting frame 31 is fixedly connected to the bottom of the traction rope 24. The outer wall of the mounting frame 31 is slidably connected to a groove on the outer wall of the support frame 1. A slider 32 is symmetrically fixedly connected to the bottom of the mounting frame 31. A fixing plate 34 is symmetrically contacted at the bottom of the mounting frame 31. The bottom of the fixing plate 34 is fixedly connected to the top of the support plate 11. The outer wall of the slider 32 is slidably connected to a groove on the outer wall of the fixing plate 34. A spring 33 is fixedly connected to the bottom of the groove of the fixing plate 34. When the traction rope 24 drives the mounting frame 31 to move upward, the mounting frame 31 drives the slider 32 to move upward, causing the spring 33 to stretch and the guide block 36 to slide on the outer wall of the slide rod 35. When the guide block 36 can no longer slide, the force of the pull rod 21 can be released. Under the action of the spring 33, the mounting frame 31 returns to its original position and then reciprocates to achieve the training purpose.

[0028] In an optional embodiment, such as Figure 2 and Figure 4 As shown, weight indicator bars are evenly arranged on the outer wall of the fixed plate 34. The weight indicator bars can be used to determine the force required to pull the counterweight component 3, so as to facilitate the adjustment of the required force.

[0029] In an optional embodiment, such as Figure 2 and Figure 4 As shown, a sliding rod 35 is fixedly connected to the bottom end of the mounting bracket 31. The sliding rod 35 is U-shaped. Guide blocks 36 are symmetrically slidably connected to the outer wall of the sliding rod 35. A movable rod 37 is rotatably connected to the bottom end of the guide block 36. The outer wall of the movable rod 37 is rotatably connected to the outer wall of the fixed plate 34. The guide block 36 slides on the outer wall of the sliding rod 35, while driving the movable rod 37 to rotate, thereby allowing the mounting bracket 31 to move up and down.

[0030] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the effective sliding stroke of the guide block 36 on the outer wall of the slide rod 35 is less than the effective sliding stroke of the slider 32 in the groove, thereby preventing the slider 32 from dislodging from the groove opened on the outer wall of the fixed plate 34.

[0031] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the adjusting assembly 4 includes a rotating rod 41, the outer wall of which is rotatably connected to the inner wall of the support plate 11. A worm gear 42 is fixedly connected to the outer wall of the rotating rod 41, and a worm wheel 43 meshes with the outer wall of the worm gear 42. A threaded rod 44 is fixedly connected to the axis of the worm wheel 43. A sleeve 46 is threadedly connected to the outer wall of the threaded rod 44. A connecting plate 45 is rotatably connected to the top end of the threaded rod 44. The outer wall of the connecting plate 45 is slidably connected to a groove on the inner wall of the sleeve 46. A limiting groove is provided on the outer wall of the sleeve 46. A limiting rod 48 is slidably connected in the groove. The bottom end of the limiting rod 48 is fixedly connected to the top end of the support plate 11. By rotating the rotating rod 41, the worm gear 42 is driven to rotate, which in turn drives the worm wheel 43 to rotate. The worm wheel 43 drives the threaded rod 44 to rotate. Under the limiting action of the limiting rod 48, the sleeve 46 moves upward on the outer wall of the threaded rod 44, which drives the top plate 47 to move synchronously. The top plate 47 then drives the counterweight assembly 3 to move upward, thereby adjusting the force required to pull the counterweight assembly 3.

[0032] In an optional embodiment, such as Figure 2 and Figure 4 As shown, a top plate 47 is fixedly connected to the top of the sleeve 46. The top plate 47 is U-shaped. When the sleeve 46 moves the top plate 47 upward, the recess in the middle of the top plate 47 will not contact the guide block 36 and the slide rod 35, thereby avoiding motion interference.

[0033] The above embodiment discloses a sports device for upper limb training. Before training, the training intensity is adjusted as needed. Rotating the rotating rod 41 drives the worm gear 42 to rotate, which in turn drives the worm wheel 43 to rotate. The worm wheel 43 then drives the threaded rod 44 to rotate. Under the limiting action of the limiting rod 48, the sleeve 46 moves upward on the outer wall of the threaded rod 44, causing the top plate 47 to move synchronously. The top plate 47 then drives the mounting frame 31 to move upward, which in turn drives the slider 32 to move synchronously, stretching the spring 33. At this time, the spring 33 is pre-stretched, increasing the initial load. Simultaneously, the guide block 36 slides on the outer wall of the slide rod 35. During the adjustment process, the current training intensity is determined by observing the position of the mounting frame 31 as indicated by the weight indicator bar. After the adjustment is completed, training can begin. Training is conducted by pulling the lever 21, which moves the fixed lever 22 downwards, causing the fixed lever 22 to slide the guide slider 23 on the outer wall of the guide rail 12. Simultaneously, the fixed lever 22 moves the traction rope 24, which in turn moves the mounting frame 31 upwards. This causes the mounting frame 31 to move the slider 32 upwards, stretching the spring 33 and causing the guide block 36 to slide on the outer wall of the slide rod 35. When the guide block 36 can no longer slide, the force of pulling the lever 21 can be released. Under the action of the spring 33, the mounting frame 31 returns to its original position, and the movement is repeated to achieve the training objective. In summary, the counterweight assembly 3 can be adjusted by adjusting the component 4, changing the force required for the pulling component 2 to pull the counterweight assembly 3, thus facilitating quick adjustment of the required weight and force for training.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
