Description

Lock for electric energy meter metering box

Technical Field

The utility model relates to an electric energy meter corollary equipment field, especially a novel electric energy meter is lock for metering box.

Background

The electric energy meter is a widely applied electric equipment matching facility, and in use, the electric energy meter accumulates and summarizes the electricity utilization data of electric equipment in families, factories and the like so as to obtain electricity utilization data statistics in a period of time. The electric energy meter is arranged at the electricity user, so that a power supply unit cannot inquire the working state of the electric energy meter at any time, and the possibility of stealing electricity for electricity utilization individuals or units without good quality is provided. General electricity stealing behavior is the chamber door of the install bin of opening electric energy meter, parallelly connected electric energy meter input wire and output wire together (for example civilian 220V electric energy meter will input the live wire and export the live wire parallelly connected back, will lead to the unable normal work of electric energy meter, and steal the electric personnel but can normal power consumption), thereby lead to the inside metering device of electric energy meter because lose input power and unable work, just also can't gather the statistics to user's power consumption, bring not little loss for power supply unit. Consequently in order to stop stealing the electricity action, current electric energy meter generally installs back in the box, the chamber door of box all locks through mechanical tool to lock, it steals the electricity operation to prevent to steal behind the electrician's the opening case door, but because general mechanical tool to lock is because of the structure is limited, do not have good function of opening of preventing, consequently relatively easily by not having good quality's people to open (for example open the tool to lock with so-called universal key), and then open the chamber door, open electric energy meter's wiring stake lid with the instrument, then parallelly connected together electric energy meter's input wire and output wire, cause electric energy meter unable normal work. Furthermore, for the management of the electric energy meter lock, due to the complexity of the operator, the management of the key has become a rather troubling example of repeated lock breaking. Moreover, the traditional key is very heavy to carry and has low safety performance.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a lock for an electric energy meter measuring box comprises an external mobile terminal, a passive lock body matched with the external mobile terminal and a lock beam which can move up and down and is arranged above the passive lock body, the lock body is internally and transversely provided with a lock core, a circuit board with a controller, a motor electrically connected with the circuit board, a second induction coil and a magnet plate which are positioned below the circuit board, the bottom of the passive lockset body is provided with a trigger area, the external mobile terminal is internally provided with a power supply and a first induction coil, when mobile terminal and passive tool to lock body triggered the district and inhale, through the electromagnetic coupling that the relative position produced between mobile terminal's first induction coil and this internal second induction coil of padlock tool to lock, the circuit board power supply control lock core that power in the mobile terminal used electromagnetic induction's mode to be padlock tool to lock body opens and shuts.

As an improvement: the mobile terminal in still be equipped with electronic key and communication module passive tool to lock body circuit board when getting electric, mobile terminal pass through communication module and send the electronic key to the controller, the controller judges whether the electronic key authentication information of record matches in received electronic key and the controller, if matches, then unlocks through control lock core, makes the lock beam can shift from top to bottom, if mismatch, then the lock core maintains at the lock state.

As an improvement: the lock beam is provided with a locking notch matched with one end of the lock cylinder, and the other end of the lock cylinder is connected with a first return spring.

As an improvement: the lock is characterized in that a lock beam bolt driven by a motor is further arranged below the lock core in the lock body, and a limit groove ring and a second reset spring matched with the lock beam bolt are further arranged on the lock beam.

The utility model discloses a lock for electric energy meter metering box owing to adopt mobile terminal and passive tool to lock body cooperation unblock for passive tool to lock body self on the electric energy meter metering box does not take power and lockhole, and passive setting makes tool to lock itself more reliable, and the volume reduces greatly, light in weight, the mobile terminal of power supply can be carried about by operating personnel can be for any passive lock body power supply, unblock, only need write in the electronic key can, convenient to use. The electronic key can be written in by adopting various modes, so that the information management is convenient, and the key management problem can be effectively solved. The intelligent lock embodies the people-oriented service safety idea and the intelligent lock safety progress in the information era. Moreover, the lock hole is not designed, so thieves have no place to use the lock, and the interior of the lock body is passive and cannot be powered for unlocking, so that the performance of the lock is safer and more reliable.

The present invention will be further described with reference to the accompanying drawings and the following detailed description.
