[0026] The present utility model provides a walkie-talkie, Figures 1 to 3 which is a specific embodiment of the walkie-talkie provided by the present utility model.

[0027] Referring to Figures 1 to 3 , the walkie-talkie includes two housings 1 and a first sealing ring 2 provided between the two housings 1;

[0028] On one side of the housing 1 close to the first sealing ring 2, a first annular groove 12 is provided. On the first sealing ring 2, a first annular block 21 inserted into the first annular groove 12 is provided, and a second annular block 22 is provided on the side surface of the first annular block 21.

[0029] On the side surface of at least one of the first annular blocks 21, a plurality of clamping blocks 23 are provided, and a notch 13 engaged with the clamping blocks 23 is provided on the surrounding wall of the first annular groove 12.

[0030] Specifically, the first annular groove 12 is an annular groove formed by enclosing with two surrounding walls. The surrounding wall located inside the first annular groove 12 is the inner surrounding wall, and the surrounding wall located outside the first annular groove 12 is the outer surrounding wall.

[0031] In this embodiment, the gap between the two housings 1 can be sealed by the first sealing ring 2 to prevent water from entering the housing 1. Through the insertion of the first annular groove 12 and the first annular block 21, the first sealing ring 2 can be limited in position, and the contact area between the housing 1 and the first sealing ring 2 can be increased, preventing the deformation of the housing 1 or the relative displacement between the housing 1 and the first sealing ring 2, which may lead to the failure of its waterproof effect. The second annular block 22 is located between the first annular block 21 and the first annular groove 12 and is squeezed by the two, which can completely seal the gap between the two, further improving the sealing effect. Through the engagement of the clamping blocks 23 and the notches 13, the first sealing ring 2 can be limited in position and can provide a positioning effect during assembly, facilitating installation.

[0032] The clamping blocks 23 are provided on the inner side surface of the first annular block 21, the notches 13 are provided on the inner surrounding wall of the first annular groove 12. The clamping blocks 23 include a first clamping portion 231 and a second clamping portion 232 provided at one end of the first clamping portion 231 away from the first annular block 21. The first clamping portion 231 is used for inserting into the notch 13, and the second clamping portion 232 is used for abutting against the inner surrounding wall of the first annular groove 12. In this embodiment, the first annular block 21 and the second clamping portion 232 respectively abut against both sides of the inner surrounding wall. The first annular block 21 and the second clamping portion 232 have a clamping effect on the inner surrounding wall, improving the connection stability between the first sealing ring 2 and the housing 1 and making the sealing effect of the first sealing ring 2 better.

[0033] The first housing 10 and the second housing 11 are connected by screws. The screw connection method can ensure the stable and reliable connection between the first housing 10 and the second housing 11, making the overall structure of the intercom more stable. It can also make the installation and disassembly between the first housing 10 and the second housing 11 simple and convenient, facilitating the user to disassemble and maintain. It should be noted that the connection method between the first housing 10 and the second housing 11 includes but is not limited to screw connection. In other embodiments, the first housing 10 and the second housing 11 can also be connected by snap connection or bonding.

[0034] The first sealing ring 2, the first ring block 21, the second ring block 22, and the clamping block 23 are provided as an integrated structure. Designing the above-mentioned multiple components as an integrated structure can simplify the assembly process, reduce the assembly steps and the requirements for docking accuracy; improve the stability of the overall structure, reduce the relative movement between components, and avoid the problem of poor waterproof effect caused by wear or vibration; the integrated structure reduces the interface gaps between the first sealing ring 2, the first ring block 21, the second ring block 22, and the clamping block 23, thereby improving the sealing effect.

[0035] Furthermore, the materials of the first sealing ring 2, the first ring block 21, the second ring block 22, and the clamping block 23 are silicone. Silicone has good elasticity and compressibility, can provide a reliable sealing effect to prevent water from entering, silicone is resistant to ultraviolet rays and oxidation, has a long service life, reduces the replacement frequency, silicone is resistant to ultraviolet rays and oxidation, has a long service life, reduces the replacement frequency.

[0036] The two housings 1 are respectively a first housing 10 and a second housing 11. A battery compartment 14 and a lid 15 for covering the battery compartment 14 are provided on a side of the first housing 10 away from the second housing 11. A second sealing ring 16 is provided between the battery compartment 14 and the lid 15. By providing the battery compartment 14 for accommodating the battery on the first housing 10 instead of placing the battery inside the first housing 10 and the second housing 11, when replacing the battery, it is not necessary to disassemble the first housing 10, the first sealing ring 2, and the second housing 11, thereby avoiding the problem of the sealing effect of the first sealing ring 2 decreasing due to disassembly and assembly. And the second sealing ring 16 can seal the gap between the lid 15 and the battery compartment 14 to prevent water from entering the battery compartment 14.

[0037] Furthermore, a second annular groove 141 for accommodating the second sealing ring 16 is provided on a side of the battery compartment 14 close to the lid 15. A third ring block 161 is provided on a side of the second sealing ring 16 close to the lid 15. The lid 15 is provided with a third annular groove 151 for inserting and connecting with the third ring block 161. The second sealing ring 16 can be limited by the second annular groove 141 to prevent the second sealing ring 16 from shifting and causing its waterproof effect to decrease. Through the cooperation of the third annular groove 151 and the third ring block 161, the sealing effect of the second sealing ring 16 can be improved.

[0038] Furthermore, the lid 15 and the first housing 10 are connected by screws. The screw connection method can ensure the connection stability between the lid 15 and the first housing 10, and make the installation and disassembly of the lid 15 convenient.

[0039] The above are only alternative embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included within the patent protection scope of the present utility model.
