The top of the product frame 3 is also provided with a handle 32, which is convenient for the product frame 3 to be put in or taken out. When the waterproof test is carried out on the mobile phone protective shell, batch waterproof tests can be realized, and the test efficiency is greatly improved.
In this embodiment, the requirement for testing the IP 67-level waterproof grade of the protective case of the mobile phone is taken as an example, and the requirement for testing the IP 67-level waterproof grade is to soak the protective case of the mobile phone with the mobile phone shape block in 1 meter of water depth under normal temperature and pressure, so that no water permeates into the protective case within 30 minutes. Therefore, the conventional testing method needs to consume a large amount of time, and the requirement of batch production is difficult to meet. The waterproof grade of the IP67 requires that the mobile phone protective case is under water pressure in a standing state in a water depth of 1 meter and lasts for 30 minutes, so that the pressure time of the mobile phone protective case can be effectively shortened by increasing the water pressure by a certain value. In this embodiment, the test time of the mobile phone protective case is greatly shortened by pressurizing the pressure measuring container 2.
