Waterproof test device

The utility model relates to a waterproof test device which comprises a container body that is made of transparent material and is provided with an upper opening. The upper part of the container body is provided with an air inlet pipe which is communicated with outside, a barometer and an air switch. The upper part of the container body is also provided with a pressure relief valve. The opening of the container body is provided with a container sealing ring. An upper cover is arranged on the container sealing ring. The upper cover is locked with the container body through hasps. The middle position of the upper cover is provided with a through hole. The waterproof test device further comprises a product bracket. The product bracket penetrates through the through hole and is sealed through the sealing ring. In use, a certain amount of water is placed in the container body. External compressed air is input into the container chamber through the air inlet pipe on the container body. Furthermore a product is dropped to a position below water surface, and air in a leaked product leaks through a leaking portion into water and therefore air bubbles are formed. Leaking points of the product can be accurately detected, and high safety of components in the product is effectively ensured.
