Abstract

The invention discloses a back sealing plate structure with an electric lock and matched with a metal armored switch cabinet. The structure comprises a back sealing plate, the electric lock and screws. The back sealing plate comprises an upper sealing plate and a lower sealing plate. The upper sealing plate is fixed with a right lateral plate and a left lateral plate of the switch cabinet through the screws and is located on the upper portion of the back side of the switch cabinet. The lower sealing plate is fixed with the right lateral plate and the left lateral plate of the switch cabinet through the screws and located on the lower portion of the back side of the switch cabinet. A lock catch of the electric lock is installed on the lower sealing plate, and the electric lock is installed on a column of the left lateral plate. Due to the fact that the back sealing plate is divided into the upper sealing plate and the lower sealing plate and are installed on the left lateral plate and the right lateral plate through the screws, the lower sealing plate can be conveniently taken down when the back sealing plate needs to be opened, and space is greatly saved. The structure is especially suitable for being installed and used in narrow space and simultaneously ensures operation safety due to the fact that the lock catch matched with a cabinet body electric lock device is installed on the lower sealing plate.

Description

Join closing plate structure after metallic armoured switch cabinet live locking
Technical field
The present invention relates to a kind of switch cabinet body structure, particularly relate to a kind of narrow space that is applicable to and install, use, closing plate structure after what safety reliability was high join metallic armoured switch cabinet live locking.
Background technology
Along with the development of switch cubicle technology and pouring in of advanced foreign technology, the cabinet type of welded type cabinet body structure and floor type handcart structure eliminates (former switch cubicle KYN1 substantially, JYN2, XGN, the 10kV switch cubicles such as GG1A are superseded), the above-mentioned cabinet produced before the nowadays former more than ten years belongs to lifetime limitation substantially; Nowadays transformation project gets more and more, most project all uses the metal armored withdrawal-type switching device that nowadays technology is quite ripe to replace original product, at present, metallic armoured switch cabinet is when installation site allows, cabinet body structure often adopts back door to join electrified locking device, and when there is electricity inlet wire side, electromagnetic lock locking back door can not arbitrarily be opened and remove; But at some because cabinet installation site limits (by wall hypotelorism or run into wall stud etc.), as adopted back door structure, debugging, use, maintenance time, back door can cannot vertically be opened, cause use inconvenient.
Summary of the invention
For the problems referred to above, main purpose of the present invention is to provide one to join closing plate structure after metallic armoured switch cabinet live locking, solves and joins metallic armoured switch cabinet in the installation of narrow location and safety, problem easy to use.
The present invention solves the problems referred to above by following technical proposals:
One joins closing plate structure after metallic armoured switch cabinet live locking, comprise rear shrouding, electric blocking, screw, it is characterized in that, described rear shrouding comprises upper sealing plate and lower shrouding, described upper sealing plate is fixed by the right plate of described screw and switch cubicle and left plate, and described upper sealing plate is positioned at the top on rear side of switch cubicle, described lower shrouding is fixed by described screw and switch cubicle right plate and left plate, and the bottom be positioned on rear side of switch cubicle, the snap close of described electric blocking is arranged on described lower shrouding, described electric blocking is arranged on the column of described left plate, described column is positioned at the side of described left plate near described upper sealing plate and lower shrouding, and be fixed together with described left plate.
In a particular embodiment of the present invention, described electric blocking is arranged on described column by electric blocking mounting panel, and the secondary connection of described electric blocking is fixed on described electric blocking mounting panel.
In a particular embodiment of the present invention, four limits of described upper sealing plate and lower shrouding are all provided with flange, installation trough rim is fixed with near the both sides of described right plate and left plate at described upper sealing plate and lower shrouding, opening groove is outward provided with in the lower end of described upper sealing plate, and the flange of described lower shrouding upper end is held in described groove, and described installation trough rim also has a plurality of installing hole.
In a particular embodiment of the present invention, described groove is trough rim.
In a particular embodiment of the present invention, the flange of described upper sealing plate and its surrounding is cut out by one whole sheet metal to be stamped to form, and the flange of lower shrouding and its surrounding is also cut out by one whole sheet metal to be stamped to form.
Positive progressive effect of the present invention is: one provided by the invention joins closing plate structure after metallic armoured switch cabinet live locking, by rear shrouding being divided into upper sealing plate and lower shrouding two parts, adopt screw to be arranged on biside plate simultaneously, after needs are opened during shrouding, only need turn on screw with spanner, just lower shrouding can be taken off, greatly save space, electric blocking is arranged on the column of left plate, and the snap close of electric blocking is arranged on lower shrouding, can guarantee to only have after joining the power-off of metallic armoured switch cabinet major loop like this, electric locking device can unload shrouding after unlocking, ensure that the fail safe of opening and joining after metallic armoured switch cabinet after shrouding, and be arranged on the column of left plate due to electric blocking, instantly when shrouding is pulled down, electric blocking does not need to pull down, facilitate the dismantlement work of lower shrouding.
