Description

Technical Field

[0001] The utility model relates to the technical field of mine auxiliary installation equipment, in particular to a shell connection component with good sealing performance. Background Technique

[0002] The intrinsically safe type, also known as the intrinsically safe type, is the safest explosion-proof type among all explosion-proof types. Whether there is an internal short circuit or a short circuit in the intrinsically safe type product, it cannot cause the explosion of flammable and explosive gases in the surrounding environment. In coal mine operations, a shell structure is required to install and protect intrinsically safe mine equipment.

[0003] The existing patent document with the publication number CN219932254U provides a shell of a mine flameproof and intrinsically safe digital display audible and visual alarm. This utility model can avoid the access of power lines, and at the same time enable staff to accurately know the closing time of the air door to avoid safety accidents.

[0004] However, when the existing shell structure installs and protects intrinsically safe mine products, it is not easy to ensure good waterproof performance. The existing shell structure can basically only meet IP54; the existing shell waterproof structure requires separate cutting of each rubber strip, resulting in a relatively high processing cost of the shell structure; the existing shell structure needs to make flanges to carry the sealing strip, resulting in waste of materials and time for the shell structure and poor practicability.
