A display slot 20 is arranged through the middle position of the watch cover 2. The display screen 5 is inserted into the display slot 20, and the side of the display screen 5 abuts with the slot body of the display slot 20. The setting of the connecting ring 51 makes it difficult for moisture to enter the inside of the watch case 1 through the connection position between the watch cover 2 and the display screen 5, thereby further increasing the airtightness of the connection between the watch cover 2 and the display screen 5.

[0054] Reference Fig.11 , Fig.12 , Fig.13 as well as Fig.14 The watch cover 2 includes a first cover body 21 and a second cover body 22. The second cover body 22 is located between the first cover body 21 and the watch case 1. The second cover body 22 is fixedly connected to the watch case 1 by multiple screws. The first cover body 21 is provided with multiple fixing holes 210. Each fixing hole 210 is threadedly connected with a fixing screw 211. Each fixing screw 211 is respectively penetrated in each fixing hole 210. Each fixing screw 211 respectively passes through the second cover body 22 and is threadedly connected to the watch case 1, so that the first cover body 21 and the second cover body 22 are further pressed and fixed to the watch case 1. Each fixing hole 210 is provided with a protective ring 212. When each fixing screw 211 is respectively penetrated in each fixing hole 210, each fixing screw 211 is respectively penetrated in each protective ring 212 and abuts against each protective ring 212. Each protective ring 212 is respectively wrapped around each fixing screw 211.

[0055] Reference Fig.11 , Fig.12 as well as Fig.15 A second sealing ring 62 is arranged between the watch case 1 and the second cover body 22, and a second sealing groove 16 is arranged around the watch case 1 on the side of the watch case 1 close to the second cover body 22. The second sealing ring 62 is penetrated and snap-fitted into the second sealing groove 16, and the second sealing ring 62 is abutted against the second cover body 22 on the side close to the second cover body 22. Each fixing hole 210 is located on the outside of the second sealing groove 16, so that moisture is not easy to penetrate into the interior of the watch case 1 from each fixing hole 210, thereby further increasing the waterproof performance of the second sealing ring 62, thereby further increasing the waterproof performance of the watch.

[0056] Reference Fig.11 , Fig.12 , Fig.13 as well as Fig.14A third sealing ring 63 is arranged between the first cover body 21 and the second cover body 22, and a third sealing groove 221 is opened on the side of the second cover body 22 close to the first cover body 21, which surrounds the length of the groove body and along the edge line of the second cover body 22, and the third sealing groove 221 is arranged opposite to the second sealing groove 16, and the third sealing ring 63 is passed through and fixed in the third sealing groove 221 and abuts against the side of the first cover body 21 close to the second cover body 22.

[0057] Reference Fig.11 , Fig.16 as well as Fig.17 A fourth sealing ring 64 is provided between the watch case 1 and the bottom case 3, and a fourth sealing groove 17 is provided on the side of the watch case 1 close to the bottom case 3. The fourth sealing ring 64 is passed through and fixed in the fourth sealing groove 17 and abuts against the bottom case 3, and each speaker hole 32 is located outside the fourth sealing groove 17, thereby further improving the waterproof effect of the fourth sealing ring 64.

[0058] In the embodiment of the present application, the diameters of the first sealing ring 61, the second sealing ring 62, the third sealing ring 63 and the fourth sealing ring 64 are all 0.9 mm, and the hardness is 55 degrees. The first sealing ring 61, the second sealing ring 62, the third sealing ring 63 and the fourth sealing ring 64 are connected without damage, the entire surface is smooth and there is no gap. The first sealing groove, the second sealing groove 16, the third sealing groove 221 and the fourth sealing groove 17 are all U-shaped grooves of 1.1 mm, with a groove depth of 0.6 mm, and there is no gap and the entire surface is flat and smooth. Therefore, when in use, the first sealing ring 61, the second sealing ring 62, the third sealing ring 63 and the fourth sealing ring 64 are compressed to 0.6 mm to achieve airtight and waterproof.

[0059] In the embodiment of the present application, the material of the first sealing ring 61, the second sealing ring 62, the third sealing ring 63 and the fourth sealing ring 64 are all selected to be soft liquid silicone, so that the connection mode between the watch case 1, the watch cover 2 and the bottom shell 3 is changed from a rigid connection to a flexible connection, so that when the watch falls, the first sealing ring 61, the second sealing ring 62, the third sealing ring 63 and the fourth sealing ring 64 can buffer the relative vibration generated between the watch case 1, the watch cover 2 and the bottom shell 3 and the instantaneous impact force generated by the fall, thereby improving the anti-collision performance of the watch. At the same time, the first sealing ring 61, the second sealing ring 62, the third sealing ring 63 and the fourth sealing ring 64 are combined with each other to form a three-dimensional multi-directional waterproof watch, thereby making the waterproof performance of the watch better. In addition, the waterproofing of the watch by applying glue is transformed into the waterproofing of the first sealing ring 61, the second sealing ring 62, the third sealing ring 63 and the fourth sealing ring 64, which makes it easier and more convenient to disassemble the watch.

[0060] The implementation principle of a waterproof structure of a watch in an embodiment of the present application is as follows: the setting of the first sealing ring 61 makes it difficult for moisture to enter the interior of the watch through the connection position between the watch cover 2 and the display screen 5 to damage the circuit module 4, thereby improving the airtightness of the connection between the watch cover 2 and the display screen 5, thereby improving the overall waterproof performance of the watch, and improving the problem that waterproofing is only achieved by the close cooperation of the watch case 1 structure, while it is not easy for the watch case 1 and the display screen 5 to achieve airtight waterproofing through structural cooperation, which leads to the problem that moisture easily enters the interior of the watch from the connection position between the shell and the display screen 5, thereby causing damage to the watch. In addition, the transition of the connection structure between the watch cover 2 and the display screen 5 is achieved through the first sealing ring 61, so that when the watch falls, the softness and elasticity of the first sealing ring 61 will play a role in buffering and shockproofing, preventing the watch cover 2 and the display screen 5 from colliding with each other due to the fall of the watch and thus causing damage.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
