Pressure gauge with protective structure

By using a sliding snap-fit ​​structure between the fixed base and the protective buckle cover, and a heating film design, the problems of low installation and disassembly efficiency of pressure gauges and unclear readings in humid environments are solved. This enables rapid assembly, stable connection, and efficient defogging, improving operational convenience and reliability.

AI Technical Summary

Technical Problem

Existing pressure gauges with protective structures suffer from inefficient installation and disassembly due to their multi-bolt fastening method, which is cumbersome to operate, increases maintenance difficulty, and causes fogging of the viewing port in humid environments, resulting in unclear readings.

Method used

It adopts a sliding snap-fit ​​structure with a fixed base and a protective buckle cover, and uses sliding grooves and locking balls to achieve quick assembly. Combined with the heating film on the inner wall of the sliding cover and button control, it can achieve rapid defogging and a stable connection.

Benefits of technology

The installation and disassembly steps have been simplified, improving the ease of operation and reliability, ensuring sealing performance and clear readings, and enhancing the reliability of the pressure gauge under complex operating conditions.

Abstract

The utility model discloses a pressure gauge with a protective structure, and relates to the field of pressure gauges. The pressure gauge comprises a gauge body, the front end and the rear end of the gauge body are provided with a fixed base and a protective buckle cover respectively, a sliding clamping structure of the fixed base and the protective buckle cover is arranged, and a sliding groove with a clamping ball is formed in a carrying groove of the fixed base. The sliding seat of the protective buckle cover slides through the sliding groove and is clamped with the clamping ball through the through hole to realize one-way locking, so that the technical problems that the mounting and dismounting efficiency is low due to the fact that a shell of an existing pressure gauge with a protective structure is fastened through multiple bolts, an operator needs to spend a lot of time to loosen and tighten the bolts one by one, and the maintenance and dismounting difficulty is increased are solved; and the heating film, the wiring port and the button on the inner wall of the sliding cover solve the technical problem that the reading of the dial plate is not clear because the visual port of the existing pressure gauge with the protection structure is easy to fog in a humid environment.
