Description

Technical Field

[0001] This utility model relates to the field of wrist fitness equipment, specifically to a wrist strength trainer. Background Technology

[0002] Wrist strength trainers are fitness devices designed to enhance the strength and endurance of the wrist muscles. Existing wrist strength trainers are relatively limited in function, typically only training wrist flexion and extension or rotation movements, failing to meet users' needs for comprehensive training of the wrist and surrounding muscles. For example, wrist balls and dumbbell wrist curls, while effectively training the wrist flexor muscles, lack targeted training for the hand's rotational muscles; while some rotational trainers cannot simultaneously perform wrist flexion and extension training. Therefore, there is an urgent need in this field to design a wrist strength trainer that integrates multiple training functions. Utility Model Content

[0003] The purpose of this invention is to provide a wrist strength trainer, which solves the problem of limited training functions in existing wrist fitness equipment.

[0004] This utility model achieves the above objectives through the following technical solutions: A wrist strength trainer includes a closed hollow frame with a handle fixed inside. The hollow frame includes a frame body and a support structure on one side of the frame body. The support structure provides a fulcrum for the forearm. The other side of the frame body has a suspension support structure I for suspending weights, and the outer side of the frame body has a limiting groove. The inner side of the limiting groove has several suspension support structures II for suspending weights.

[0005] As a further optimization of this utility model, the supporting structure is provided with reserved holes on both sides, and the reserved holes are used for the binding strap to pass through.

[0006] As a further optimization of this utility model, the reserved hole is an oblong hole.

[0007] As a further optimization of this utility model, the side of the limiting groove away from the supporting structure is arc-shaped or near-arc-shaped.

[0008] As a further optimization of this utility model, the side of the limiting groove away from the supporting structure is arc-shaped, and the handle passes through the center of the limiting groove.

[0009] As a further optimization of this utility model, the grip is perpendicular to the central axis of the hollow frame.

[0010] As a further optimization of this utility model, the second suspension support structure is located at the end of the limiting groove.

[0011] As a further optimization of this utility model, the hollow frame is provided with a pair of edge-reducing baffles on the top and bottom outer edges, the second suspension support structure is connected to the heavy object through a flexible connector, and the edge-reducing baffles are used to stop the flexible connector.

[0012] As a further optimization of this utility model, a groove is formed between the paired edge baffles. The groove is composed of a wide groove, a transition groove and a narrow groove, and the second suspension support structure is arranged adjacent to the wide groove.

[0013] The beneficial effects of this utility model are as follows: 1) This utility model integrates the functions of wrist flexion and extension training and hand twisting training by setting a suspension support structure in the area of ​​the hollow frame away from the supporting structure, and setting a limiting groove and another set of suspension support structures on the outside of the hollow frame, so that the wrist strength trainer can comprehensively exercise the wrist-related muscle groups. 2) This utility model sets the limiting groove as an arc shape, and the handle passes through the center of the limiting groove. During rotation training, it can guide the weight to move along a stable and smooth arc trajectory, thereby improving the stability and training effect of hand twisting training. 3) This utility model limits the flexible connectors that connect to the weight by setting a pair of edge-retaining baffles on the outer edge of the frame, preventing the upper part of the flexible connectors from coming out of the limiting groove during hand twisting training, thereby improving the safety of the equipment and enhancing the training effect. 4) By setting a reserved hole for the strap to pass through, this utility model can fix the forearm and the supporting structure together with the strap, providing a solid fulcrum when performing wrist flexion and extension training, and improving the standard of training movements and the efficiency of force exertion.

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] First Embodiment like Figure 1 and Figure 2 As shown, this embodiment relates to a wrist strength trainer, which includes a closed hollow frame 1. The upper and lower edges of the inner side of the hollow frame 1 are chamfered, and a handle 2 is fixedly mounted on the inner side of the hollow frame 1. A hand hole H is formed inside the hollow frame 1, and the handle 2 extends through the hand hole H, and the handle 2 is perpendicular to the central axis of the hollow frame 1. The hollow frame 1 includes a frame body 11 and a support structure 12 disposed on one side of the frame body 11. The support structure 12 is used to provide a fulcrum for the forearm. Figure 2 The dotted line in the diagram is the boundary line between the frame body 11 and the supporting structure 12. In addition, the hollow frame 1 is formed by splicing an upper shell and a lower shell. The front part of the upper shell and the front part of the lower shell form the frame body 11, and the rear part of the upper shell and the rear part of the lower shell form the supporting structure.

[0017] On the other side of the frame body 11, there is a suspension support structure 3 for suspending a heavy object G, and a limiting groove 4 is provided on the outer side of the frame body 11. Inside the limiting groove 4, there are several suspension support structures 5 for suspending the heavy object G. The suspension support structure 3 is preferably a lifting ring, and the suspension support structure 5 is preferably a straight suspension rod, with both ends of the suspension rod fixedly installed between the top and bottom of the frame body 11. In other embodiments, the suspension support structure 3 can be replaced by a hook or a suspension rod, and it can also be replaced by a connecting hole opened on the frame body 11. In other embodiments, the suspension support structure 5 can also be replaced by a hook or a lifting ring. Two suspension support structures 5 are provided, each located at one end of the limiting groove 4. In other embodiments, the suspension support structure 5 can be provided only at one end of the limiting groove 4, and it can also be located at other parts of the limiting groove 4.

[0018] Please see Figure 3-5This wrist strength trainer has two working modes: wrist flexion and extension training mode and hand twisting training mode. Figure 3 This demonstrates the working state of the wrist strength trainer during wrist flexion and extension exercises. Figure 4 and Figure 5 This demonstrates the working state during hand twisting training.

[0019] like Figure 3 As shown, when training wrist flexion and extension, the weight G is suspended below the suspension support structure 3. Then, the user holds the handle 2, the frame body 11 is in a horizontal or near-horizontal tilted state, the user's forearm is against the top of the support structure 12, and the handle 2 is moved up and down with the support structure 12 as the fulcrum, so that the frame body 11 swings along the R1 direction and returns to its original position, thereby exercising the muscle groups related to wrist flexion and extension.

[0020] like Figure 4 and Figure 5 As shown, when training hand twisting movements, the weight G is connected to the suspension support structure 5 via a flexible connector C. In this embodiment, the flexible connector C is preferably a connecting strap. When suspending the weight G, the two ends of the connecting strap are respectively tied to the weight G and the suspension support structure 5. Then, the user holds the handle 2, the frame body 11 is in a vertical position, the user's forearm does not touch the hollow frame 1, and the user performs hand twisting movements, causing the frame body 11 to swing along the R2 direction and return to its original position, thus exercising the muscle groups related to hand twisting movements.

[0021] Furthermore, in this embodiment, the side of the limiting groove 4 away from the supporting structure 12 is arc-shaped, and the axis of the grip 2 passes through the center of the limiting groove 4. The side of the limiting groove 4 away from the supporting structure 12 is the side of the limiting groove 4 separated from the supporting structure 12 by the axis of the grip 2. In this embodiment, the remaining part of the limiting groove 4 is also arc-shaped, and the entire limiting groove 4 is curved in an arc. In other embodiments, the remaining part of the limiting groove 4 may also be straight or semi-arc-shaped. In this embodiment, when the user holds the middle of the grip 2 and rotates the wrist strength trainer, the frame body 11 is stably stressed during the swinging process, which can improve the wrist strength training effect. In other embodiments, the side of the limiting groove 4 away from the supporting structure 12 may also be semi-arc-shaped, such as an elliptical arc.

[0022] Furthermore, in this embodiment, the support structure 12 has pre-drilled holes 6 on both sides for the strap to pass through. The pre-drilled holes 6 are waist-shaped holes. When training wrist flexion and extension movements, the user can pass a strap through the two pre-drilled holes 6 and use the strap to tie the forearm to the support structure 12, restricting the rotation of the hollow frame 1 relative to the user's forearm axis, making the fulcrum more secure and improving the training effect.

[0023] Second Embodiment like Figure 6 and Figure 7 As shown, this embodiment relates to another wrist strength trainer. The difference between this embodiment and the previous embodiment is that this embodiment further constrains the flexible connector C by using the edge baffle 7 to prevent the flexible connector C from moving away from the limiting groove 4 on the side close to the suspension support structure 2 5 during training.

[0024] Specifically, the hollow frame 1 has paired edge-retaining baffles 7 on its top and bottom outer edges. During hand twisting exercises, the second suspension support structure 5 is connected to the weight G via a flexible connector C. The edge-retaining baffles 7 stop the flexible connector C, which is preferably a connecting strap. A groove 8 is formed between the paired edge-retaining baffles 7. The groove 8 consists of a wide groove, a transition groove, and a narrow groove. The second suspension support structure 5 is positioned adjacent to the wide groove. The wider wide groove facilitates the user's fixation of the connecting strap on the second suspension support structure 5. The transition groove, located between the wide and narrow grooves, prevents the user's hand from being scratched by the edge-retaining baffles 7 when fixing the connecting strap. The narrower narrow groove allows the edge-retaining baffles 7 to effectively stop the flexible connector C from moving away from the limiting groove 4 on the side closest to the second suspension support structure 5 during hand twisting exercises.

[0025] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of this utility model.
