Description

Lock economize on electricity cabinet is separated in interlock

Technical field

The utility model belongs to economize on electricity cabinet field, relates generally to a kind of economize on electricity cabinet with special back door lock.

Background technology

For the ease of maintenance, some economize on electricity cabinet is provided with a back door, and the general lock of installing supplies and the cabinet locking on the back door of tradition economize on electricity cabinet; But this lock only needs outer buttons twist lock handle to get final product release; Anyone can both open the back door like this, is easy to touch inner circuit and components and parts if amateur operating personnel open the back door, and danger such as electric shock take place easily; Also damage internal wiring and components and parts easily, cause serious consequence easily.

The utility model content

In order to overcome above-mentioned defective; The utility model provides a kind of interlock to separate lock economize on electricity cabinet, and the fail safe that lock economize on electricity cabinet has increased the back door is separated in this interlock, can prevent that amateur operating personnel from arbitrarily opening the back door; Reduce potential safety hazard, and simple in structure, easy to implement.

The utility model for the technical scheme that solves its technical problem and adopt is:

Lock economize on electricity cabinet is separated in a kind of interlock, and the economize on electricity cabinet has Qianmen and back door, the back door lock is installed for back door and cabinet locking on the said back door; The said back door lockset dead bolt that has a back door connection, said back door dead bolt is positioned at the front side, back door, and the cabinet front portion is equipped with internal lock; Said internal lock is positioned at the rear, Qianmen, and said Qianmen can lock with cabinet, and said internal lock has interior lock keyhole and interior dead bolt; The moving interior dead bolt rotation of lock keyhole rotating band is provided with locking bar in the interior lock key insertion in the cabinet, and said locking bar front end is fixedly connected with said interior dead bolt; When interior dead bolt rotates to internal lock when being in the lock state; The said back door of backstop, said locking bar rear end dead bolt rotates, and when interior dead bolt rotated to the internal lock release, said locking bar broke away from said back door dead bolt.Because internal lock stops back door lock release through locking bar, therefore only opens the Qianmen later on again with the internal lock release, the back door can be opened, and has increased the fail safe at back door, can prevent that amateur operating personnel from arbitrarily opening the back door.

Dead bolt and back door dead bolt are all the dead bolt that in perpendicular, rotates release in said; When internal lock locks with the back door lock; Interior dead bolt all is the level of state with the back door dead bolt and is vertical each other; When the internal lock release, interior dead bolt is vertical state, and dead bolt upwards rotates back to front in the internal lock releasing process.When internal lock locked, the locking bar rear end placed dead bolt top, back door, stoped back door dead bolt rotation, and the back door dead bolt can't rotate up, thereby does not open the back door; Internal lock release after the interior lock keyhole rotation of interior lock key insertion internal lock; Dead bolt upwards rotates 90 degree back to front in the internal lock releasing process, and owing to the locking bar front end is fixedly connected with said interior dead bolt, so dead bolt pulling locking bar moves back to front in the internal lock releasing process; Make locking bar break away from the back door dead bolt; So far locking bar loses backstop action to the back door dead bolt, and the back door dead bolt is without hindrance, and the back door can be opened.

Said back door lockset has shank of the key, and said shank of the key is fixedly connected with the back door dead bolt, and said shank of the key is positioned at the back door rear side, and the rotation shank of the key drives back door dead bolt rotation.Promptly the back door lock does not have key, and when locking bar was without hindrance to the back door lock, the shank of the key that only needs to rotate the back door lock can be opened the back door.

Said back door lockset has lockhole, and said lockhole is positioned at the back door rear side, and rotation drove the dead bolt rotation of said back door after back door key inserted lockhole.Promptly the back door lock is identical with the structure of internal lock, when locking bar is without hindrance to the back door lock, and also need be with rotating and could the back door be opened behind the back door key insertion lockhole.

On the cabinet sidewall between said internal lock and the back door lock, be fixed with location-plate, offer perforation on the said location-plate, said locking bar is through in the said perforation, and promptly locking bar is positioned on the cabinet sidewall through location-plate, and can freely move forward and backward.

The beneficial effect of the utility model is: be provided with locking bar in the cabinet of the utility model, the locking bar front end is fixedly connected with interior dead bolt, when interior dead bolt rotates to internal lock when being in the lock state; Backstop back door, locking bar rear end dead bolt rotates; When interior dead bolt rotated to the internal lock release, locking bar broke away from the back door dead bolt, because internal lock stops back door lock release through locking bar; Therefore only open the Qianmen later on again with the internal lock release; The back door can be opened, and has increased the fail safe at back door, can prevent that amateur operating personnel from arbitrarily opening the back door.
