Title:
PRESSURE GAUGE FIXING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/087989
Kind Code:
A1
Abstract:
A pressure gauge fixing device, comprising: a movement unit (100), which comprises a pressure gauge assembly (101), and a supporting assembly (102) connected to the pressure gauge assembly (101); a fixing and limiting unit (200), which comprises a sleeve supporting assembly (201), and a limiting assembly (202) provided above the sleeve supporting assembly (201); and a protection unit (300), which comprises a gear assembly (301) connected to the pressure gauge assembly (101), and a protection assembly (302) connected to the gear assembly (301). The pressure gauge assembly (101) is rotated to drive the supporting assembly (102) to move downwards and be fitted to the sleeve supporting assembly (201) and the limiting assembly (202) for internal fixation and support, thereby achieving simultaneous fixation in four directions. The fixing device is disposed internally, which has an anti-theft effect, and a pressure gauge is protected by means of the gear assembly (301) and the protection assembly (302), thereby prolonging the service life of the pressure gauge. The limitation to the limiting assembly (202) can be canceled by means of a disassembly hole (201h).
