Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a disassembly automatic alarm type water meter. Background Art

[0002] A water meter is an instrument that records the amount of tap water used. When a user releases water, the pointer or wheel on the meter rotates to indicate the amount of water passing through for billing purposes. Some unrelated personnel may use some means to remove the water meter or change the water meter reading to make a profit. When the water meter is removed, the water supply company cannot know that the water meter has been removed and cannot prevent users from stealing water in time. Therefore, an alarm system needs to be installed on the water meter to inform people that someone has removed the water meter privately, which serves as an alarm.

[0003] For example, the Chinese patent application with application number 202222019246.6 provides an anti-disassembly alarm type NB-IOT remote water meter, which includes a water pipe, a water meter body fixedly installed on the top of the water pipe, an anti-disassembly structure provided on the outer surface of the water pipe, an alarm component provided inside the water meter body, a remote control valve fixedly installed on the top of the water meter body, a protective frame fixedly installed on the top of the water meter body, and the anti-disassembly structure includes two support frames fixedly installed on the outer surface of the water pipe, a second support plate fixedly installed on the top of each of the two support frames, a fixing piece fixedly installed on the right side of the left second support plate, and a support rod fixedly installed between the inner bottom wall and the inner top wall of the two fixing pieces. This technical solution has the advantages of anti-disassembly and alarm after forced disassembly, which improves the stability of the installation of the NB-IOT remote water meter and the safety of the NB-IOT remote water meter.

[0004] However, the following problem still exists in this technical solution: in this technical solution, the sliding block is driven by the first spring to fix the two second support plates together. However, as time goes by, the elastic potential energy of the spring will gradually decrease, and its own elastic force will eventually be unable to continue to fix the two second support plates together. Utility Model Content

[0005] To this end, an embodiment of the present invention provides a disassembled automatic alarm water meter to solve the problem in the prior art that the two second support plates cannot be fixed due to the reduction of the elastic potential energy of the spring.
