Abstract
Dual fail-safe three-phase electric energy meter box, including the mounting plate inside electric energy meter casing and electric energy meter casing, it is provided with through-hole on the electric energy meter casing, seal screw is set in the through-hole, the seal screw screws up effect so that electric energy meter casing is fixedly connected with mounting plate by screw thread, the side of the through-hole also sets up strip-shaped hole, and padlock is arranged on the mounting plate, and the padlock passes through strip-shaped hole.The utility model has the advantages that：On the basis of seal screw lead sealing electric energy meter casing, increase padlock, realize the closed function of dual fail-safe, anti-theft grade improves.
Description
Technical field
The utility model belongs to electric energy meter field, and in particular to dual fail-safe three-phase electric energy meter box.
Background technology
Three-phase kilowatt-hour meter batch meter is a kind of for installing the metering device of three-phase electric energy meter, is power department to three-phase electricity consumption
Family carries out the foundation of meterage, and due to China's rapid development of economy, the user of three-phase kilowatt-hour meter batch meter is millions of at present
Meter.
The poor safety performance of existing electric energy metering box, in general, the mounting plate of shell and bottom is that seal screw is fixed
, a hinged thin plastic sheet is hidden above, but plastic sheet is easy to manually be poked, and is then opened with screwdriver,
It sneaks current.
Invention content
For deficiency in the prior art, the utility model provides dual fail-safe three-phase electric energy meter box, to solve existing three
The problem of phase electric energy meter shell and mounting plate are fixed only by a point print screw, and dismounting is relatively simple, anti-theft energy force difference.
The utility model is achieved through the following technical solutions.
Mounting plate inside dual fail-safe three-phase electric energy meter box, including electric energy meter casing and electric energy meter casing, which is characterized in that
It is provided with through-hole on the electric energy meter casing, seal screw is set in the through-hole, the seal screw passes through screw thread
Effect is screwed up so that electric energy meter casing is fixedly connected with mounting plate, the side of the through-hole also sets up strip-shaped hole, the peace
Padlock is set in loading board, and the padlock passes through strip-shaped hole.Double safety device is added, electric energy meter casing basically can not be beaten
It opens, unless implementing destructive damage to padlock, but also therefore can send out larger noise, cause the vigilance of people around.
Preferably, lock is arranged on the padlock.Lock on padlock can arbitrarily be customized according to situation.
Preferably, the padlock is rectangle.
Preferably, fillet is arranged on the padlock.
Preferably, height of the padlock from electric energy meter casing in 0.5cm between 1cm.
Preferably, the through-hole apart from padlock 1cm between 3cm.
Preferably, height 0.5cm of the padlock from electric energy meter casing.
Preferably, height 0.8cm of the padlock from electric energy meter casing.
Compared with prior art：On the basis of seal screw lead sealing electric energy meter casing, increases padlock, realize dual fail-safe
Closed function, anti-theft grade improve.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the transparent window of the utility model.
Fig. 3 is the structural schematic diagram of the sunshading board of the utility model.
Specific implementation mode
Mounting plate inside dual fail-safe three-phase electric energy meter box, including electric energy meter casing 1 and electric energy meter casing 1, the electricity
It can be provided with through-hole 2 on watch shell 1, seal screw is set in the through-hole 2, the seal screw screws up work by screw thread
With making electric energy meter casing 1 be fixedly connected with mounting plate, the side of the through-hole 2 also sets up strip-shaped hole, the mounting plate
Upper setting padlock 3, the padlock 3 pass through strip-shaped hole, lock are arranged on the padlock 3, the padlock 3 is rectangle, institute
Fillet is set on the padlock stated, height of the padlock from electric energy meter casing 1 in 0.5cm between 1cm, the through-hole 2
Apart from padlock 1cm between 3cm, height of the padlock from electric energy meter casing 1 is 0.5cm, and the padlock is from electric energy meter
The height of shell 1 is 0.8cm.
During the installation process, the shell of electric energy meter is placed on mounting plate first, then through-hole 2 is aligned on mounting plate
Threaded hole squeezes into seal screw, and seal screw makes the lower part of electric energy meter casing be fixedly connected with mounting plate, can not open, and rises
To preliminary antitheft effect.
Since in installation process, the position of strip-shaped hole is overlapped with the position of padlock 3, padlock 3 passes through strip-shaped hole, extend out to outer
The exposed part in portion hangs up lock on padlock 3, can play secondary antitheft effect.
And lock needs individual key to go to open, therefore anti-theft effect is better than seal screw.
Hinged sunshading board 4 during the motion, can be opened at any time, observe internal reading, due to positioning column 41 with
The position alignment of positioning groove 51, positioning groove 51 are interference fitted with positioning column 41, and positioning column 41 can stick into positioning groove 51
It is interior, form buckle structure.
Therefore wind effect is less than sunshading board 4, and sunshading board 4 will not all encounter transparent window 5, significantly no matter opening and closing several times
Protect transparent window.
The scope of protection of the utility model includes but not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Subject to sharp claim, any replacement being readily apparent that those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
