Description

Technical Field

[0002] In a broad sense, a testing machine is an instrument used to verify the quality or performance of a product or material according to design requirements before it is put into use. As the definition shows, any instrument used to verify quality or performance can be called a testing machine. Electronic products undergo pressure immersion testing before being released to the market.

[0003] Patent CN207501977U discloses a pressure immersion testing machine. This machine features a sealing gasket on the lower surface of the cylinder cover, located between a concave ring and a convex part. A sealing ring is provided between the upper end of the side wall of the cylinder and the lower surface of the cylinder cover. Several hook-and-loop fasteners are evenly distributed along the outer circumference of the cylinder cover on its side wall. Hook-and-loop hooks, corresponding to the hook-and-loop fasteners, are provided on the upper end of the outer wall of the cylinder. Through the sealing gasket, sealing ring, and hooks, the sealing performance between the cylinder cover and the cylinder is increased, thereby improving the pressure-bearing capacity of the cylinder. However, the heating method used in this testing machine is slow and requires a long time. Furthermore, the complex component structure results in high power consumption, increasing the operating cost of the testing machine. Utility Model Content
