The waterproof structure prevents water from entering the rotating cooperation assembly and causing damage to the equipment. The waterproof structure is simple and stable and meets the waterproof requirements of low-angle shooting of ecologists.

However, the water vapor inside will continue to cover the outside of the sealing ring, which is not conducive to the long-term stable use of the sealing ring. Utility model content

[0040] The working principle of the above embodiment is as follows:

[0041] In use, the servo motor 403 drives the transmission shaft 404 to rotate, and the transmission shaft 404 drives the transmission cylinder 302 to rotate, thereby allowing the gimbal body 2 to rotate, so that the top-mounted camera can also rotate to meet the shooting requirements. Through the cooperation between the conical ring 305 and the annular groove 306, the top of the mounting cylinder 301 can be effectively protected from dust and water. Under the action of the first sealing ring 308, further waterproof effect can be achieved, thereby effectively preventing water from entering the inside of the mounting cylinder 301 and protecting the internal structure. If water enters the inside of the mounting cylinder 301, it can be further blocked by the waterproof sealing bearing 309, making it difficult to continue to flow. If the water pressure is too large, the water will flow through the waterproof sealing bearing 309, and the cooperation between the second sealing ring 311 and the third sealing ring 314 can effectively prevent water from entering, thereby protecting the working environment of the servo motor 403. By pulling out the special-shaped sealing element 407, the water inside the mounting cylinder 301 can be poured out through the drain hole 405, preventing excessive internal water from affecting the actual service life.

[0042] Compared with the prior art, the waterproof gimbal structure can effectively prevent water from entering through the cooperation between the sealing assembly 300 on the top of the base 1 and the gimbal body 2, thereby ensuring the long-term use of the internal structure. At the same time, multiple waterproof measures are also provided inside the structure, so that even if water enters the inside of the structure through the waterproof structure on the outside, it will be blocked by the internal measures, thereby reducing the amount of water entering the inside as much as possible. At the same time, it is also convenient to drain the water inside after a period of work, which is beneficial to the long-term stable use of the internal structure, thereby effectively improving the practicality of the waterproof gimbal structure and solving the problem that the existing gimbal waterproof structure can easily allow external water to enter during actual use, causing the internal waterproof structure to be continuously soaked in water and affecting the actual service life.
