[0020] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0021] See also Figure 1-3 As shown, an arm strength competition device of the utility model comprises two symmetrically arranged support plates 1, the support plates 1 are trapezoidal in shape, a plurality of detachable connecting rods 3 are arranged between the support plates 1, a rotating shaft 5 penetrating and rotatably connected to the support plates 1 is arranged above the support plates 1, handwheels 6 are arranged at both ends of the rotating shaft 5, an electrical box 7 rotatably connected to the rotating shaft 5 is arranged in the middle sleeve of the rotating shaft 5, two warning lights 4 for displaying colors are arranged above the electrical box 7, control components 2 for controlling whether the warning lights 4 are on are arranged on the left and right sides of the rotating shaft 5, and the control components 2 are electrically connected to the warning lights 4. By adopting two trapezoidal support plates 1 and a plurality of connecting rods 3 to assemble into an integral structure, when force is applied on both sides at the same time, the force on the overall structure is more The force is added evenly and has good performance in dispersing the force, so that the overall structure is more stable when used. When in use, two contestants stand on both sides respectively, and then rotate the handwheel 6 according to the indication of the rotating arrow 10. When the arm strength of one party is greater than that of the other party, the rotating shaft 5 rotates in the direction of rotation of the contestant with greater arm strength under the action of the handwheel 6, so that the connecting rod 21 touches the two connecting terminals 22 on one side, thereby connecting the circuit of the battery pack 23 and the warning light 4, so that the corresponding warning light 4 lights up, so as to quickly judge which party wins. The device has a simple structure, low production cost, and is easy to move. It is suitable for various competition venues and can quickly judge the winning or losing situation of the two sides of the game in a standard manner.

[0022] Specifically, the control component 2 includes a battery pack 23, a connecting rod 21 and two connecting terminals 22. The battery pack 23 is arranged on the electrical box 7. The two connecting terminals 22 are arranged side by side on the electrical box 7 on one side of the rotating shaft 5. One of the connecting terminals 22 is electrically connected to the battery pack 23, and the other connecting terminal 22 is electrically connected to the warning light 4. The connecting rod 21 is vertically arranged on the rotating shaft 5. The positive pole of the battery pack 23 is connected to the connecting terminal 22, and the negative pole of the battery pack 23 is directly connected to the warning light 4. When the two connecting terminals 22 are connected, the entire circuit is connected, so that the warning light 4 lights up, so that the person with greater arm strength can be quickly judged.

[0023] Preferably, the terminal 22 is made of a metal spring material, and the length of the connecting rod 21 is greater than the distance from the terminal 22 to the rotating shaft 5. The metal spring can conduct electricity and has a certain elasticity, which can effectively prevent the connecting rod 21 from instantly applying excessive pressure to the terminal 22, thereby damaging the terminal 22. When the connecting rod 21 is knocked down, the terminal 22 can be bent and can still be in contact and conduct electricity.

[0024] Furthermore, the warning lights 4 are a red warning light and a green warning light, which are arranged on both sides of the rotating shaft 5 respectively. The red warning light and the green warning light display different lights, which is helpful for the referee to quickly determine which side wins.

[0025] Furthermore, the handwheel 6 is connected to the rotating shaft 5 in an eccentric shaft connection manner, and a rotation arrow 10 is provided on the outer side of the handwheel 6, so that when the rotating shaft 5 is in a natural state, the connecting rod 21 is in a middle vertical direction, so that the connecting rod 21 is in a fair original position, so that after the game is completed, the device automatically restores its state for use by the next group.

[0026] Furthermore, a support seat 9 for supporting the rotating shaft 5 is provided above the support plate 1 , and an arc groove matched with the rotating shaft 5 is opened on the support seat 9 to support the rotating shaft 5 so that the rotating shaft 5 rotates more smoothly.

[0027] Furthermore, an auxiliary support rod 8 vertically connected to the support plate 1 is provided in the middle position of the outer side thereof. During the competition, the contestant can use one hand to act on the hand wheel 6 and the other hand to act on the auxiliary support rod 8, which plays an auxiliary supporting role and is helpful to maintain the body's balance.

[0028] Furthermore, both ends of the connecting rod 3 are detachably connected to the support plate 1 through locking bolts 11, which is convenient for installation and disassembly of the device. The multiple connecting rods 3 are arranged in a triangular shape, so that the force is more uniform and the overall structure is more stable.

[0029] When the arm wrestling contest device of the present embodiment is used, two contestants stand on both sides respectively, and then rotate the hand wheel 6 according to the indication of the rotating arrow 10. When the arm strength of one party is greater than that of the other party, the rotating shaft 5 rotates in the direction of rotation of the contestant with greater arm strength under the action of the hand wheel 6, so that the connecting rod 21 touches the two connecting terminals 22 on one side, thereby connecting the circuit of the battery pack 23 and the warning light 4, so that the corresponding warning light 4 lights up, so as to quickly determine which party wins. This device has a simple structure, low production cost, and is easy to move. It is suitable for various competition venues, and can quickly determine the winning or losing situation of the two parties in the competition. The arm wrestling contest device of the present utility model is suitable for arm wrestling competitions between primary and secondary school students, and can be moved at will, effectively increasing the applicable scenes, and has the characteristics of easy use and strong practicality.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
