Description

Technical Field

[0001] This utility model relates to the field of pressure detection technology, specifically to a data storage pressure gauge with a protective structure. Background Technology

[0002] Currently, in the hydraulic transmission industry, pressure gauges are typically installed on pipelines to monitor the real-time pressure of pressure systems. However, most pressure gauges are currently mechanical. As market demands for product quality continue to rise, the requirements for pressure gauges have expanded beyond simply displaying pressure levels. Mechanical pressure gauges can only display real-time pressure and lack memory to store information. For some hydraulic systems requiring long-term monitoring of pressure changes or troubleshooting leaks, intelligent pressure gauges with data storage capabilities are widely used. However, intelligent pressure gauges contain internal electrical components, and prolonged vibration and impact can damage these components, affecting the accuracy of the measured data.

[0003] Authorization Announcement No. CN221594162U; Authorization Announcement Date: August 23, 2024; This invention discloses a pressure gauge with a protective structure, including a pressure gauge body and a protective structure. The protective structure is disposed on the outside of the pressure gauge body and includes an outer protective layer, an inner protective layer, and a buffer assembly. The buffer assembly is disposed between the outer protective layer and the inner protective layer. This invention provides a pressure gauge with a protective structure, which effectively prevents damage to the pressure gauge body from external wind, rain, and foreign object impacts, thereby protecting the pressure gauge and solving the problem of poor protection in existing systems.

[0004] The problem with the above technical solution is that, since the buffer push rod is set in the two vertical directions of top and left and right, when the pressure gauge body moves left and right, it is restricted by the buffer push rod at the top, and when the pressure gauge body moves up and down, it is restricted by the buffer push rods on the left and right sides. That is, the pressure gauge body cannot move relative to the outer protective layer, so it cannot play a buffering role and the pressure gauge body cannot be effectively protected.
