Description

Technical Field

[0001] This utility model relates to the field of probe clamp technology, and in particular to a probe clamp for an ultrasonic flow meter. Background Technology

[0002] Existing ultrasonic flow meter probe clamps leave the flow meter exposed after use, making it susceptible to damage from impacts and scratches, offering insufficient protection. A Chinese patent (application number CN202222041518.2) discloses an ultrasonic flow meter probe clamp that improves stability and secureness by incorporating a fixing clamp and drive assembly, preventing it from falling off. An adjustable fitting plate maintains a close fit to the pipe, preventing large gaps that could cause stress damage. The probe is also easy to install and remove, facilitating the placement of the ultrasonic flow meter probe clamp. However, this clamp lacks a protective mechanism, making it prone to damage to the ultrasonic flow meter after prolonged use, indicating a lack of protection. Utility Model Content

[0024] Specifically, before using the ultrasonic flow meter, it needs to be extended from the rectangular outer frame 1. Start the reversible motor 20 inside the U-shaped horizontal guide rail 8. The reversible motor 20 will drive the horizontal screw 7 to rotate forward. The horizontal screw 7 will drive the horizontal slider 19 to move forward. The horizontal slider 19 will drive the slide 14 to move forward. The ultrasonic flow meter clamped at the front end of the slide 14 will move forward until it extends out of the rectangular outer frame 1.
