Abstract

The invention discloses an electric meter box having an electricity stealing prevention alarm function and a door opening alarm device thereof. The door opening alarm device comprises a fixed shell, a flexible rod, a first spring, a fixed cover body, a groove body, a first proximity switch, a second proximity switch, a connecting rod, a flexible shell, a locking block, a second spring, an operating member, a third spring, a locking member, a fourth spring and a shaft body. The door opening alarm device is reasonable and simple in structure, low in production cost and convenient to install. The door opening disconnection device can effectively guarantee that the electricity of the electric meter box is disconnected after the box door is opened so that the possibility of electricity stealing can be avoided. The door opening alarm device can effectively guarantee that the door opening signal is transmitted to a wireless alerter after the box door is opened, and the alarm horn rings to be a certain deterrent to the electricity stealer. According to the door opening alarm device, unlock operation requires to be performed before closing the door, or the signal of the second proximity switch is transmitted out to alarm by the wireless alerter after the door is closed.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an electric meter box with an anti-theft alarm function and a door opening alarm device. Background technique [0002] The meter box is a special meter box for installing single-phase watt-hour meters or three-phase watt-hour meters, which is used to measure and display the electricity consumption of users. In the meter box, there are usually an incoming line switch, a watt-hour meter and an outgoing line switch. The power of the grid or power supply line is sent to the watt-hour meter through the incoming line switch, and then connected to the user's incoming line terminal or load end through the outgoing line switch. Connect to realize the measurement and display of the user's electricity consumption. For a long time, in order to achieve the purpose of paying less or no electricity bills, some users have taken various methods to destroy the electricity metering equipment, res...
