Abstract

The utility model relates to an electricity meter box, which comprises a box body. A box door is arranged on the box body; the box body and the box door are connected by hinges; a padlock which is used for locking a slide bar is arranged on the slide bar of a rotary disc type slide bar lock. The utility model has the advantages that the padlock which is used for locking the slide bar is arranged in the box body, which breaks the routine thinking; on the one hand, people can not think upon that the box body is provided with the padlock which is used for locking the slide bar inside; on the other hand, the padlock which is arranged in the box body is hard to be stolen, so the electricity meter box is prevented from being pounded, pried, pressed, blocked and exposed to the wind and rain. Simultaneously, nobody dares to extend the hand or tools into the box body to carry out prying because afraid of the electric shock. Thus, the anti-prying performance of the electricity meter box is enhanced.

Description

The metering ammeter box

The utility model belongs to a kind of electric equipment protection device, particularly a kind of metering ammeter box.

At present, the metering ammeter of China all is installed in the ammeter box, to prevent artificial destruction and to prevent stealing, protection power equipment and electric power netting safe running.Existing metering ammeter box is made with steel plate, and it is made up of casing, chamber door and door lock.Chamber door links together with common folding or split type folding and casing, door lock adopts common drawer-lock or rotating disc type slide bar lock, the problem that this metering ammeter box exists is exactly the pick-proof poor performance, mainly show the following aspects: 1, the pick-proof poor performance of chamber door, existing chamber door mostly is flat, its not bending of edge or have only a very little flanging, and directly cover on the doorway of casing, this door structure makes to be taken off the sled thing and is easy to be inserted in the crack between a door and its frame and goes, and prizes chamber door bad; 2, the pick-proof poor performance of folding, the rotation axis in the common folding is easy to be drawn out of, in case rotation axis is drawn out of, chamber door will be taken, and the pick-proof performance of split type folding is just poorer; 3, door latch structure is too simple, and power department often adopts unified key in order to work conveniently, and this just makes the pick-proof performance of door lock poorer.Investigation according to statistics, China all has a large amount of metering ammeter boxes to be pried open, press off or push aside every year, and a lot of power equipments are damaged, and many stealing electricity phenomenons take place, and national wealth is sustained losses severely, and have influence on the safe operation of electrical network.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, solves the problem that the metering ammeter box exists, and provides a kind of pick-proof performance good metering ammeter box.

The utility model is achieved in that

It has a casing, and chamber door is housed on the casing, and casing is connected with folding with chamber door, on the slide bar of the inboard rotating disc type slide bar lock of chamber door the padlock that is locked is housed.

In order to improve the pick-proof performance of casing and chamber door, the doorway of casing is the concave type gate slot, and there is the square flanging that matches with gate slot at the edge of chamber door.

In order to improve the pick-proof performance of folding, the folding on the chamber door is positioned at the inboard or the outside of casing folding, prevents that chamber door from being held

The utility model compared with prior art has following advantage:

1, on the slide bar of rotating disc type slide bar lock the padlock that is locked is housed, this padlock is arranged in the casing, has broken conventional thought.People can not expect locking in addition in the casing padlock of slide bar on the one hand, the padlock that is arranged on the other hand in the casing also is difficult to take off sled, avoided being pounded, prized, pressed, blocked up and wind and weather, simultaneously, get an electric shock because be afraid of, also nobody dares handle or instrument and extend into and take off sled in the casing, thereby has improved the pick-proof performance of metering ammeter box greatly

2, the doorway of casing is the concave type gate slot, and the edge of chamber door adopts the flanging of square, can embed fully in the gate slot of casing after chamber door is closed, and takes off the sled thing and is not easy to be inserted in the crack between a door and its frame and goes, and has improved the pick-proof performance of chamber door, simultaneously, has also improved the intensity of chamber door.

3, the folding on the chamber door is positioned at the inboard or the outside of casing folding, played to prevent that chamber door from being held the effect of getting off, thereby, further improved the pick-proof performance of metering ammeter box
