[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Please refer toFigures 1 to 5 , the present utility model provides a technical solution: a surrounding soundproof cover for a mahjong machine, including an upper cover body 2 and a lower cover body 3 located inside the upper cover body 2. A upper positioning ring 1 is fixedly connected at the center of the upper cover body 2, and a lower positioning ring 4 is fixedly connected at the center of the lower cover body 3. An internal thread 401 is provided on the inner circumference of the lower positioning ring 4, and an external thread 103 is provided on the outer circumference of the lower end of the upper positioning ring 1. The lower positioning ring 4 can be threadedly installed at the lower end of the upper positioning ring 1. The upper cover body 2 and the lower cover body 3 are made of a material that can effectively soundproof, such as silicone material. The silicone material has good elasticity and softness, and can effectively absorb and reduce sound transmission; the silicone material has good sealing performance; this enables the silicone cover body to block the sound transmission path to a certain extent, thereby improving the soundproof effect.

[0025] The upper cover body 2 and the lower cover body 3 adopt a detachable and assembled connection method, so as to adjust the soundproof effect according to the actual situation. When the upper cover body 2 and the lower cover body 3 are combined together, the soundproof effect can be improved; when the two are separated, the use economic cost can be reduced; this design not only increases the flexibility of users in actual use, but also enables them to adjust according to different environments or personal preferences to obtain the best soundproof effect.

[0026] A retaining ring 8 is fixedly connected to the outer circumferential side wall of the upper positioning ring 1. When the lower positioning ring 4 is installed at the bottom end of the upper positioning ring 1, the top end of the lower positioning ring 4 is in contact with the retaining ring 8; specifically, when the lower positioning ring 4 is screwed onto the bottom end of the upper positioning ring 1, it is continuously rotated until the top end of the lower positioning ring 4 is in contact with the retaining ring 8, and then the rotation is stopped to achieve the preliminary positioning of the lower positioning ring 4.

[0027] A limiting opening 102 is provided on the inner circumferential wall of the upper positioning ring 1, and a limiting component is fixedly installed on the inner circumferential wall of the lower positioning ring 4.

[0028] The limiting component includes a positioning block 5 fixed to the inner wall of the lower positioning ring 4, a rotating shaft 6 rotatably inserted into the positioning block 5, and a limiting block 7 fixed to the end of the rotating shaft 6. When the lower positioning ring 4 is locked, the limiting block 7 rotates into the limiting opening 102.

[0029] When the lower positioning ring 4 is screwed onto the bottom end of the upper positioning ring 1, the top end of the lower positioning ring 4 is in contact with the retaining ring 8, so as to achieve the connection purpose of the lower cover body 3 and the upper cover body 2, and rotate the limiting block 7 into the limiting opening 102 to achieve the locking purpose of the lower positioning ring 4 and avoid loosening.

[0030] A plurality of circumferentially distributed gaps 201 are provided on the surface of the upper cover body 2. The surface with the gaps 201 can promote the air flow inside the mahjong machine and help with heat dissipation; when the mahjong machine is running, it may generate a certain amount of heat. Through the gaps 201 on the surface, the hot air can more easily escape from the soundproof cover, avoiding too high temperature inside the cover and affecting the performance and lifespan of the mahjong machine.

[0031] A through hole 101 is formed in the upper positioning ring 1.

[0032] When using this device, the upper positioning ring 1 is sleeved on the central rod at the bottom of the control panel, and is locked by passing a bolt through the through hole 101 and screwing it into the threaded hole on the surface of the central rod, so as to achieve the positioning purpose.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention, and do not limit the present invention.
