[0033] The present invention will now be further described with reference to the accompanying drawings.
[0034] A waterproof structure for a watch includes a cover 1 and a base 2 that overlap each other. The cover 1 has an insert 1-1 arranged on the contact surface between the cover 1 and the base 2. The base 2 has a slot 2-1 arranged on the contact surface between the base 2 and the cover 1. When the cover 1 and the base 2 are assembled, the insert 1-1 is inserted into the slot 2-1. The contact area between the cover 1 and the base 2 is increased by the cooperation of the insert 1-1 and the slot 2-1, thereby increasing the sealing performance of the cover and the base.
[0035] To further improve the sealing of the connection between the cover 1 and the base 2, a slot 2-2 is provided on the base 2. The slot 2-2 is located inside the slot 2-1. The end face of the cover 1 and the base 2 is in contact with the slot 2-2. The slot 2-2 is used to collect the liquid flowing through the insert 1-1, further preventing the liquid from flowing into the meter, thereby playing a further waterproof role. In this embodiment, two inserts 1-1 are provided on the cover 1. Correspondingly, two slots 2-1 are provided in the base 2. The two inserts 1-1 are respectively inserted into the slots 2-1. The slot 2-2 is located between adjacent slots 2-1.
[0036] A module slot 1-2 is provided on the cover 1, which is connected to the interior of the meter. The module slot 1-2 facilitates the connection of the external antenna to the circuit board inside the meter. An opening slot 1-7 is provided on the side wall of the module slot 1-2, and a silicone plug assembly 3 is installed in the opening slot 1-7. The antenna extends out of the cover 1 through the silicone plug assembly 3. A module cover 4 is installed on the cover 1 to cover the module slot 1-2. The module cover 4 abuts against the silicone plug assembly 3 to ensure the sealing performance of the silicone plug assembly 3.
[0037] The watch cover 1 is provided with fixing screws 1-8 and rotating buckles 1-9. The fixing screws 1-8 and rotating buckles 1-9 are respectively located on both sides of the watch cover 1. The watch cover 1 is fixed to the watch base 2 by fixing screws 1-8 and rotating buckles 1-9. The rotating buckles 1-9 are used to assemble one side of the watch cover 1 with the watch base 2. This can reduce the number of screws used, thereby improving the assembly efficiency of the watch cover 1 and the watch base 2.
[0038] A guide arc groove 1-10 is provided inside the rotating buckle 1-9. Correspondingly, a fastening block 2-3 is provided inside the watch base 2. The guide arc groove 1-10 is fastened to the fastening block 2-3, thereby enabling the rotating buckle 1-9 to be connected to the watch base 2 through the fastening block 2-3. To ensure the sealing of the watch cover 1 and watch base 2 assembly on the side where the rotating buckle 1-9 and fastening block 2-3 are connected, a guide arc surface is provided at the bottom of the fastening block 2-3. The guide arc surface is adapted to the guide arc groove 1-10. When the rotating buckle 1-9 moves toward the fastening block 2-3, the guide arc groove 1-10, under the guidance of the guide arc surface, causes the rotating buckle 1-9 to move toward the watch base 2. When the guide arc groove 1-10 and the guide arc surface are fastened, the mating surfaces of the watch cover 1 and watch base 2 are tightly contacted under the action of the guide arc surface, thereby ensuring the sealing of the watch cover 1 and watch base 2 assembly.
[0039] The watch base 2 has a fastening groove 2-6, and two partition plates 2-7 are provided inside the fastening groove 2-6, thereby dividing the fastening groove 2-6 into two slots 2-1 and an empty slot 2-2. The watch base 2 has a fixing post 2-4 for connection with fixing screws 1-8. A semi-circular baffle 2-5 is provided on the inner side of the fixing post 2-4, and the semi-circular baffle 2-5 is connected to the inner side wall of the fastening groove 2-6 to improve the waterproof performance of the fixing post 2-4.
[0040] The silicone plug assembly 3 includes a mounting block 3-5 installed in the opening groove 1-7 and a detachable plug 3-6 arranged on the mounting block 3-5. A sealing ring 3-7 is provided in the middle of the plug 3-6 to ensure the sealing between the plug 3-6 and the mounting block 3-5. When the antenna module is required, the plug 3-6 is removed and the antenna extends out of the meter through the hole where the plug 3-6 is located. When the marking does not involve the antenna module, the plug 3-6 is inserted into the mounting block 3-5 to adapt to different functional requirements of the meter.
[0041] Two parallel insertion plates are provided in the opening slot 1-7. Correspondingly, a first step slot 3-1 and a second step slot 3-2 are provided on the mounting block 3-5. The two insertion plates in the opening slot 1-7 are respectively inserted into the first step slot 3-1 and the second step slot 3-2 to increase the assembly sealing between the opening slot 1-7 and the mounting block 3-5. After the module cover 4 is closed on the cover 1, the module cover 4 abuts against the second step slot 3-2 to ensure the connection sealing between the module cover 4 and the second step slot 3-2.
[0042] To facilitate the connection of the second stepped groove 3-2 with the opening groove 1-7 and the module cover 4 respectively, the second stepped groove 3-2 includes a first groove 3-3 and a second groove 3-4, wherein the first groove 3-3 is connected to the opening groove 1-7, the second groove 3-4 is connected to the module cover 4, and the first groove 3-3 and the second groove 3-4 are connected.
[0043] The end face connecting the module slot 1-2 and the module cover 4 is provided with a first sealing surface 1-3 and a second sealing surface 1-4 at different heights. The second sealing surface 1-4 is set higher than the first sealing surface 1-3. A sealing ring 4-1 is provided on the module cover 4. The end face of the sealing ring 4-1 abuts against the first sealing surface 1-3, and the inner wall of the module cover 4 abuts against the second sealing surface 1-4, thereby increasing the sealing performance of the connection between the module cover 4 and the module slot 1-2.
[0044] A certain gap is provided between the outer wall of the sealing ring 4-1 and the edge of the module cover 4 to form an extended sealing surface 4-2. A waterproof buffer surface 1-5 is provided on the outer side of the module groove 1-2. The height of the waterproof buffer surface 1-5 is higher than the height of the second sealing surface 1-4, and the extended sealing surface 4-2 abuts against the waterproof buffer surface 1-5 to play a waterproof buffering role.
[0045] Screw posts 1-6 are provided on both sides of the module slot 1-2, and the two sides of the module cover 4 are connected to the screw posts 1-6 by screws.
