Description

Technical Field

[0001] This utility model relates to a capillary shock absorption structure for a pressure gauge. Background Technology

[0002] The capillary tube of a pressure gauge is designed in a coiled structure to effectively mitigate the instantaneous pressure impact of the measured medium on the pressure gauge and extend the instrument's service life. This design increases the fluid path length, allowing pressure changes to be transmitted to the measuring element more smoothly. However, during transportation or handling, vibrations occur. If these vibrations cannot be eliminated or reduced, the coiled capillary tubes are prone to collisions, which may crack or break the capillary tubes. Therefore, more careful transportation or handling is required, resulting in high transportation or handling costs. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a capillary shock-absorbing structure for a pressure gauge. The capillary is spirally coiled, and during transportation, the shock-absorbing pad structure prevents collisions between the capillary tubes, thereby avoiding capillary breakage caused by collisions. The structure is simple, safe and reliable.

[0004] To achieve the above objectives, this utility model provides a capillary shock-absorbing structure for a pressure gauge, comprising a pressure gauge; its key feature is that it also includes... Capillary tube and fitting; the fitting is located on the pressure gauge, and one end of the capillary tube is located on the fitting and connected to the pressure interface of the pressure gauge. Positioning sleeve and shock-absorbing rubber pad structure; the positioning sleeve is fitted on the capillary tube and located at the end of the capillary tube near the pipe joint, and the shock-absorbing rubber pad structure is provided on the positioning sleeve and located between the spirally coiled tubes of the capillary tube.

[0005] In this technical solution, the shock-absorbing rubber pad structure includes a fixing ring and a rubber pad. The fixing ring is sleeved on the positioning sleeve, and the rubber pad is disposed on the fixing ring. The rubber pad is located between the capillary spiral coiled tubes.

[0006] In this technical solution, the edge of the rubber pad is arc-shaped to prevent the capillary from being scratched and broken.

[0007] The advantages of this utility model compared with the prior art are: during transportation, the shock-absorbing rubber pad structure prevents collisions between capillary tubes, thereby avoiding capillary rupture caused by collisions. The structure is simple, safe and reliable. Attached Figure Description
