Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and more specifically, to a sealing pressure detection device. Background Technology

[0002] When conducting sealing pressure tests on bags, technicians need to use a pressure testing instrument. The pressure testing instrument is used for pressure resistance testing, pressure holding testing, and vacuum pressure holding testing using helium and nitrogen as the testing medium. It is also used in refrigeration, air conditioning, and other production workshops that require gas filling pressure tests and vacuum leak tests.

[0003] A search revealed a jelly sealing pressure testing device (publication number CN212872154U), comprising an upper panel, support columns, a lower panel, a screw, an electronic scale, and a pressure plate. The four corners of the upper panel are connected to the four corners of the lower panel via support columns. The screw passes through the upper panel and is fixed to the pressure plate. The pressure plate is located between the upper and lower panels. An electronic scale is mounted on the upper surface of the lower panel. This device can test the sealing strength of jelly; it is ingeniously designed, has a simple structure, and is worthy of widespread application.

[0004] When inspecting the sealing of bags, pressure can cause the bags to rupture, leading to splashing of contents and contamination of the inspection area. Therefore, we propose a sealing pressure testing device to address these issues. Utility Model Content
