[0002] Arm wrestling is a sport that compares arm and wrist strength. Arm wrestling is based on the strength of the whole body, with special emphasis on the coordination of wrist strength and arm and wrist strength. The most important muscle is the ulnar extensor carpi. They are a very important part of human movement. They are responsible for the movement of the wrist and fingers, and play an important role in daily life and sports. The function of this muscle is to bend the wrist, which is assisted by the extensor digitorum and the radial carpi brevis. Training the ulnar extensor carpi can also assist in training the biceps, the muscles on the inside of the forearm, the deltoid muscles, and the back muscles. It is also important in sports that use tools, including golf, tennis, cricket, squash, hockey, bowling, etc. In racket sports, it is particularly important when hitting the ball.

[0003] If you want to practice the ulnar wrist extensor muscles, you need to choose the right equipment.

[0040] like Figure 1-4 The ulnar wrist extensor muscle training device shown comprises: a support 1 providing a training platform, a rotating wheel 2, a weight component, a guide component and a protective layer component.

[0041] The support 1 comprises a flat training platform, preferably a square one. A through hole 11 is provided in the middle of the training platform, which runs through the vertical direction and serves as a space for installing the rotating wheel 2. The support 1 plays a role in supporting the rotating wheel 2 in the air.

[0042] Preferably, the support 1 includes two legs 12 for supporting the training platform. The legs 12 are located on the left and right sides of the through hole 11.

[0043] The rotating wheel 2 is provided with a through hole 11, and both ends of the central axis of the rotating wheel 2 are rotatably supported by the through hole 11, so that the rotating axis of the rotating wheel 2 is located on the training platform, and can be on the training platform together with the protective layer component. A handle 21 tilted upward is provided on the top of at least one edge of the front or back of the rotating wheel 2; the rotating wheel 2 can be equipped with a handle 21 located on the front or back, or handles are installed on both the front and back. It is convenient for the trainer to train while standing on the front or back.

[0044] Preferably, a sponge cover 211 is provided on the handle.

[0045] Among them, the counterweight component includes a connecting rope 3, one end of which is fixed to the bottom of the rotating wheel 2, preferably fixed to the side of a circle of the rotating wheel 2. When in use, the connecting rope can be wound around the rotating wheel 2, and preferably a winding groove is opened on the side of the rotating wheel 2. The other end of the connecting rope can be connected downward to a plurality of counterweight blocks 33 located in the counterweight box 32, and the rotating wheel 2 rotates to drive the connecting rope 3 to lift the counterweight block 33. The structure of the counterweight component is prior art, and can be referred to the Chinese utility model patent with application number CN202122642877.9 and application name "A multifunctional adjustable fitness equipment". Or the Chinese utility model patent with application number CN202020121935.6 and application name "A training device".

[0046] Preferably, a plurality of counterweights 33 can be selectively connected to the connecting rope 3 as required. The other end of the connecting rope 3 can be connected to different numbers of counterweights as required.

[0047] The guide component includes two pulleys 41 located below the rotating wheel and a pulley bracket 42 for rotating the connecting pulleys 41. The middle part of the connecting rope 3 passes through the middle of the two pulleys 41, and the pulley bracket 42 is fixedly connected to the bracket 1. Since the connecting rope sags due to the gravity of the counterweight, in order to guide the connecting rope 3 as vertically as possible, a guide component is provided to guide the connecting rope 3 to connect vertically to the counterweight.

[0048] The protective layer component includes a support pad 51 facing the central axis and buffer pads 52 located on both sides of the support pad 51; the support pad 51 is located between the two buffer pads 52 because the wheel can rotate in both directions, so the buffer pads are designed in different directions.

[0049] The support pad 51 is used to support the elbow. After holding the handle 21 and rotating the wheel 2, the hand can fall on the buffer pad 52.

[0050] When in use, the wheel rotates when the ulnar wrist extensor muscle exerts force, and the connecting rope is wound to drive the counterweight upward. When the hand touches the buffer sponge pad, the force is slowly unloaded, so that the counterweight moves straight up and down to ensure safety.

[0051] Preferably, the counterweight block 33 slides with the counterweight box 32 in the counterweight box 32. Specifically, a plurality of counterweight blocks 33 are stacked in the counterweight box 32, and two slide bars 34 passing through the counterweight blocks 33 are erected in the counterweight box 32. The counterweight block 33 is slidably connected to the slide bar 34.

[0052] The counterweight component also includes an adjustment rope 36, a horizontal adjustment rod 35, and an insertion rod 37 erected on the bottom surface of the counterweight box.

[0054] One end of the adjusting rope 36 is sleeved on the outside of the top end of the insertion rod 37, and the other end of the adjusting rope 36 is fixedly connected to the adjusting rod 35; the function of the adjusting rope 36 is to connect the adjusting rod to the insertion rod 37 to prevent loss.

[0055] The adjusting rod 35 can be penetrated with the jacks of the counterweight 33 and the insertion rod 37. The adjusting rod fixes the penetrated counterweight and the insertion rod 37 together like this, and the penetrated counterweight and the counterweight above it can be moved together with the insertion rod 37.

[0056] The handle of the rotating wheel is turned by exerting force on the wrist of one hand, and the handle drives the rotating wheel and connects the connecting rope. The rotating wheel is connected to the counterweight component, and the weight adjusted by the adjusting rod is connected to the rotating wheel through the insert rod. When the ulnar wrist extensor muscle exerts force, the rotating wheel rotates, driving the counterweight block upward. When the hand touches the buffer pad, the force is slowly unloaded, so that the counterweight block moves straight up and down to ensure safety. The handle, bracket, and protective layer components form a bowl structure, which provides good guidance for the ulnar wrist extensor muscle training movements. With the assistance of the equipment, the movements will become more standardized, the risk of exercise is greatly reduced, and injuries are reduced.

[0057] Preferably, the handle 21 is detachably connected to the rotating wheel 2, and at least one of the front or back sides of the rotating wheel 2 is provided with a row of handle holes 23 for connecting the handle 21, and the row of handle holes 23 is perpendicular to the training platform. This is to be practical for trainers with different arm lengths. The handle hole 23 can be a bolt hole, and the handle 21 is provided with a thread, and the two are detachably connected through the thread.

This makes it convenient for the exerciser to select the initial exercise position.

[0059] The handle 21 is covered with a movable sleeve that can move along the handle 21. The handle 21 rotates along the center of the rotating wheel on one hand, and rotates along the elbow on the other hand. Due to the flexibility of the wrist and the movement of the hand, the paths of the handle 21 on both sides can be approximately equal. However, in order to increase the comfort of the human hand during exercise, the human hand can be held on the movable sleeve.

[0060] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
