Description

Technical Field

[0002] Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed when the ultrasonic sound beam propagates in the water downstream and upstream, analyzes and processes the water flow rate, and further calculates the water flow rate. Long-term use can easily cause scale to accumulate inside the ultrasonic water meter, affecting the flow rate of the liquid. The ultrasonic water meter needs to be inspected and maintained regularly. Traditional intelligent ultrasonic water meters are generally fixed to the pipeline through a flange bolt structure during installation. The process of disassembly and installation is cumbersome and takes a long time. Therefore, it needs to be improved;

It includes a water meter body, and connecting mechanisms are symmetrically fixedly installed at both ends of the water meter body. A fixing mechanism is provided on the surface of the connecting mechanism, and the fixing mechanism includes a fixing block. A mounting hole is provided at the central position of one side of the fixing block close to the connecting mechanism, and two groups of card grooves are provided on one side of the inner wall of the mounting hole. The central positions of the two sides of the fixing block are symmetrically provided with mounting grooves, and a fixing rod is slidably installed inside the mounting groove. The installation structure of the ultrasonic water meter is provided with a connecting mechanism and a fixing mechanism, and the two groups of pull plates are pulled to drive the fixing rod to retract into the corresponding mounting groove, and the connecting ring is inserted into the corresponding mounting hole so that the fixing hole corresponds to the fixing rod. The pull plate is released, and under the rebound action of the fixing spring, the fixing rod is inserted into the corresponding fixing hole to fix and install the water meter body.

[0004] The water meter can be fixedly installed by spring-clipped locking mechanism for the fixed plug rod. However, the elastic locking structure has the following defects: when in use, the elastic locking structure needs to be arranged on the inner side of the water meter body, which is inconvenient to manufacture, and the locking mechanism is complicated and easy to be damaged. At the same time, when the locking structure is installed, the water meter and the pipeline cannot be firmly connected, and the sealing performance is poor. Utility Model Content
