Abstract
The invention discloses a linkage unlocking power saving cabinet which comprises a front door and a back door, wherein a back door lock for the back door to be connected with a case is installed on the back door, the back door is provided with a back door lock bolt positioned on the front side of the back door, an inner lock which is mounted in the front of the case is positioned behind the front door, the front door can be locked to the case, the inner lock is provided with an inner lock keyhole and an inner lock bolt, an inner lock key is inserted into the inner lock keyhole to rotate to drive the inner lock bolt to rotate, a lock bar is arranged in the case, and the front end of the lock bar is fixedly connected with the inner lock bolt. When the inner lock bolt rotates into a state that the inner lock is locked, the back end of the lock bar blocks rotation of the back door lock bolt. When the inner lock bolt rotates to a state that the inner lock is unlocked, the lock bar is released from the back door lock bolt. The inner lock prevents unlocking of the back door lock through the lock bar, so that the back door is opened only when the inner lock is unlocked after the front door is opened. Safety of the back door is improved, and the problem that unprofessional operators open the back door freely can be avoided.
Description
Technical field
The invention belongs to the electricity-saving cabinet field, relate generally to a kind of electricity-saving cabinet with special back door lock.
Background technology
For the ease of maintenance, some electricity-saving cabinet is provided with a back door, the general lock of installing is for locking with cabinet on the back door of tradition electricity-saving 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 the danger such as electric shock occur easily, also damage easily internal wiring and components and parts, cause easily serious consequence.
Summary of the invention
In order to overcome defects, the invention provides a kind of linkage unlocking power saving cabinet, this linkage unlocking power saving cabinet has increased the fail safe at back door, can prevent that amateur operating personnel from arbitrarily opening the back door, reduces potential safety hazard, and simple in structure, easy to implement.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of linkage unlocking power saving cabinet, electricity-saving cabinet has Qianmen and back door, back door lock is installed for back door and cabinet locking on the described back door, described back door lock has the back door dead bolt, described back door dead bolt is positioned at the front side, back door, the cabinet front portion is equipped with internal lock, described internal lock is positioned at the rear, Qianmen, described Qianmen can lock with cabinet, described internal lock has interior lock keyhole and interior dead bolt, lock keyhole rotarily drove interior dead bolt rotation in interior lock key inserted, and was provided with locking bar in the cabinet, and described locking bar front end is fixedly connected with described interior dead bolt, when interior dead bolt rotates when being in the lock state to internal lock, the described back door of backstop, described locking bar rear end dead bolt rotates, and when interior dead bolt rotated to the internal lock release, described locking bar broke away from described back door dead bolt.Because internal lock stops the back door lock release by 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.
Described interior dead bolt and back door dead bolt are all the dead bolt that rotates release in perpendicular, when internal lock and back door lock locking, interior dead bolt all is the level of state with the back door dead bolt and is mutually vertical, 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, because the locking bar front end is fixedly connected with described interior dead bolt, therefore dead bolt pulling locking bar is mobile back to front in the internal lock releasing process, so that locking bar breaks 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.
Described back door lock has shank of the key, and described shank of the key is fixedly connected with the back door dead bolt, and described 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.Be that back door lock does not have key, when locking bar was without hindrance to back door lock, the shank of the key that only needs to rotate back door lock can be opened the back door.
Described back door lock has lockhole, and described lockhole is positioned at the back door rear side, and rear door key rotarily drives the dead bolt rotation of described back door after inserting lockhole.Be that back door lock is identical with the structure of internal lock, when locking bar is without hindrance to back door lock, also needs and to rotate and the back door could be opened behind the rear door key insertion lockhole.
Cabinet sidewall between described internal lock and back door lock is fixed with location-plate, offers perforation on the described location-plate, and described locking bar is through in the described perforation, and namely locking bar is positioned on the cabinet sidewall by location-plate, and can freely move forward and backward.
The invention has the beneficial effects as follows: be provided with locking bar in the cabinet of the present invention, the locking bar front end is fixedly connected with interior dead bolt, when interior dead bolt rotates when being in the lock state to internal lock, backstop back door, locking bar rear end dead bolt rotates, when interior dead bolt rotates to the internal lock release, locking bar breaks away from the back door dead bolt, because internal lock stops the back door lock release by locking bar, therefore only open the Qianmen later on again with the internal lock release, the back door can be opened, increased the fail safe at back door, can prevent that amateur operating personnel from arbitrarily opening the back door.
