Abstract

The invention discloses a water meter demounting prevention device, which comprises a shell, a positioning shaft, a positioning shaft sleeve and a tension spring. The shell is divided into left and right halves which are connected with a groove I and a groove II respectively, and a connection shaft is arranged on a connection plate I which is arranged in the groove I. An elastic part and a magnetic part are sequentially arranged between the connection plate I and the shell; the magnetic part is connected with the positioning shaft sleeve; the positioning shaft sequentially penetrates the positioning shaft sleeve, the magnetic part and the elastic part to sleeve the connection shaft; a clamping fastener in clamp connection with the magnetic part sleeves the connection shaft, and the tensionspring and a limiting part arranged on the connection plate I jointly control rotation of the clamping fastener; a connection plate II in clamp connection with the clamping fastener is arranged at the end of the groove II. The water meter demounting prevention device has advantages that opening and closing of the demounting prevention device can be realized, the demounting prevention device can only be opened with a specific ferromagnetic key to enable demounting of a water meter, and accordingly problems of meter stealing and water stealing can be prevented. In addition, the water meter demounting prevention device is recyclable, resource waste and environmental pollution are avoided, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of water meters, and in particular relates to a water meter anti-disassembly device. Background technique [0002] At present, there are many kinds of products in the water meter industry. Among them, if a detachable water meter is damaged during use, the screws on the water meter can be unscrewed to remove the water meter for maintenance or replace the movement. This simplifies However, it also brings unsafe factors to the use of the water meter. Some users illegally remove the detachable part of the water meter in order to reduce the payment of water charges, which leads to the inability of the water meter to realize the metering function during normal use, thus giving The water supply sector brings losses and also causes waste of water resources. [0003] In order to solve the above problems, researchers have designed anti-dismantlement devices for water meters, and installed anti-dismantlement devices a...
