Water meter anti-theft device

Abstract

The present invention relates to the technical field of protective devices, in particular to a water meter anti-theft device, which includes a storage chamber for placing a water meter and a water pipe connection joint, snap rings at both ends of the storage chamber, and the storage chamber is along the direction of the center of the pull ring There is an opening through the side wall of the storage cavity, and grooves embedded in the side walls of the storage cavity are provided in the direction of the two side walls of the pull ring, and the water pipe and The connection joint of the water meter is set in the accommodation cavity, so that the user cannot disassemble the water meter, which solves the problem that some unscrupulous residents steal water by changing the direction and modifying the water meter in life; When repairing and replacing the water meter, use a wrench to break it upward along the direction of the pull ring, and a groove is provided, so that the maintenance personnel can easily pull up the pull ring along the direction of the groove to open the accommodating cavity, so as to facilitate the maintenance of the water meter. The problem that the anti-theft device in the prior art is difficult to disassemble after installation is solved.

Description

Technical field: [0001] The invention relates to the technical field of protection devices, in particular to a water meter anti-theft device. Background technique: [0002] A water meter is an instrument for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. They originated in the United Kingdom. The development of water meters has a history of nearly two hundred years. , you should first estimate the size and flow range of the flow normally used, and then choose the water meter of the specification with the usual flow closest to the value as the first choice. The internal structure of the water meter can be divided into three parts: the shell, the sleeve and the inner core from the outside to the inside. The shell is made of cast iron. After the water comes out of the water inlet, it passes through the lower annular space of the shell, which is called the "lower...

Problems solved by technology

For this reason, Chinese Patent No. 93220904.1 provides a kind of water meter anti-theft water lock mother, and this device needs to lengthen the water inlet pipe joint nut and perforate on the hexagonal nut, brings a lot of troubles to the resident who installs this lock mother, does not need simultaneously To facilitate the maintenance of water meters, Chinese Patent No. 95228002.7 provides an anti-theft device for water meters, which includes two lock nuts. The lock nuts are curved and made of injection molding. The straight groove that matches the head, and the hole that communicates with the straight groove

In actual use, it is indeed guaranteed to a certain extent that residents will not steal water. However, after the water meter has been used for a period of time, the water meter needs to be repaired and replaced. And this process is irreversible, it is difficult for maintenance personnel to remove the device, which brings a lot of difficulties to the maintenance of water meters
