Technical Field

[0001] The utility model relates to the technical field of performance testing devices, in particular to a performance testing device for a power distribution product. Background Art

[0002] For power distribution products, waterproof performance has become an important development trend. Waterproof performance is not only a reflection of product advantages, but also gradually becomes an indispensable product feature, especially for power distribution products worn on people, such as smart watches and smart bracelets. Such products often accompany users in various environments. If the waterproof performance is too poor, water will enter the interior of the electronic product, which can easily cause product failure, thereby greatly reducing the quality of the product.

[0003] Among the existing waterproof testing methods, one is to soak the product in water for a period of time, then take it out of the water, and then check its water ingress. This method is low-cost and can be used for large-scale testing. However, the structure of the existing distribution product waterproof performance testing device is relatively simple, and the product is only placed in a sink or other structure, which makes it difficult to take the distribution product. If auxiliary tools are used, the surface of the distribution product may be worn, affecting its appearance.

[0004] Therefore, a power distribution product performance testing device is proposed. Utility Model Content

[0008] As a further optimization scheme of the utility model, a positioning plate is fixedly connected to the inner wall of the water tank, a limiting rod is fixedly connected to the side of the rack, and a limiting groove matching the limiting rod is opened on the side of the positioning plate.

[0009] As a further optimization solution of the utility model, a retaining ring is fixedly connected to the top of the bearing plate, and the outer diameter of the retaining ring is the same as the outer diameter of the bearing plate.

[0010] As a further optimization solution of the present utility model, the overall structure formed by the positioning plates and the limiting rods has two groups, and is symmetrically distributed along the vertical center axis of the bearing plate.

[0011] As a further optimization solution of the utility model, a guide rod is fixedly connected to the inner bottom wall of the water tank, and a guide groove matched with the guide rod is opened inside the bearing plate.

[0012] As a further optimization solution of the present invention, there are two guide rods, and the two guide rods are symmetrically distributed along the vertical center axis of the water tank.

[0013] As a further optimization solution of the utility model, a limiting ring is fixedly connected to the top of each guide rod.
