Water meter anti-disassembly and anti-theft device

Abstract

The invention provides a water meter anti-disassembly and anti-theft device, which comprises water pipes, a water meter disc, fastening apparatuses and a water meter pipe, the two sides of the water meter pipe are connected with the water pipes through the fastening apparatuses, and the water meter disc is arranged in the middle of one side of the water meter pipe; and each fastening apparatus comprises an upper arc-shaped part and a lower arc-shaped part which are symmetrically arranged up and down. According to the water meter anti-disassembly and anti-theft device, the detachable fasteningapparatuses are arranged at the connecting positions of the water pipes and the water meter pipe and used for fixing connection between the water pipes and the water meter pipe, the fastening apparatus is fixed through a connecting screw rod between the upper arc-shaped part and the lower arc-shaped part, and meanwhile the upper arc-shaped part and the lower arc-shaped part are each provided witha corresponding positioning clamping plate and a corresponding clamping groove; the two positioning clamping plates and the clamping grooves are oppositely arranged, and the positioning clamping plates on the upper arc-shaped part and the lower arc-shaped part can be clamped into the clamping grooves at the same time, so that the sealing performance of the fastening apparatuses can be improved, and then the anti-disassembly and anti-theft effects of the water meter are improved.

Description

technical field [0001] The invention relates to the field of water meters, in particular to a water meter anti-disassembly and anti-theft device. Background technique [0002] At present, with the development of water meters, there are more and more users of electronic water meters. During the use of electronic water meters, there may be abnormal phenomena in the metering devices during operation. This may be caused by abnormal internal calibration parameters. At present, water meters have been used in various industries. With the rapid development of electronic information technology, electronic water meters have gradually become the development direction of the water meter industry. Enterprises or measurement departments that produce water meters need to perform performance verification on the indication errors of these water meters in accordance with the verification regulations formulated by relevant departments. [0003] However, as the functions of smart water meters ...
