Description
The present invention relates to the annex in the cabinet of communication equipment, but be specifically related to a kind of multiple spot locking, gate lock for cabinet of communication equipment with good seal performance.
Be equipped with door lock in existing most cabinet of communication equipment, moving of lock catch of door lock generally all adopts several transmission schemes such as rack-and-pinion transmission, connecting rod transmission to realize that its appearance and modeling is also each has something to recommend him, and most of door locks can only be realized some locking.Also have some door locks can realize multi-point fastening, motion mode of locking bar is generally and rotates and swing about it.
In existing gate lock for cabinet, most of door lock only can be realized some locking, so just can not realize the electromagnetic shielding of communication equipment with rack, this is that the slit between door-plate and the frame just can not get effective shielding like this because some locking of door lock can not compress shielding material fully.
Also some telecommunications equipment cabinet usefulness door lock can be realized the multi-point fastening to door-plate, has bigger coupling mechanism force.But their most locking bar motion modes up and down are swing and rotation, so just require rack that bigger space will be arranged, and be limited with the operating space in the rack at most of communication equipments, in addition, the unlatching handle of this class door lock can not lock, so their great majority do not meet the requirement of all communication equipments with rack.
Main purpose of the present invention is, a kind of telecommunications equipment cabinet door lock is provided, and can realize the locking and the unlatching of rack cabinet door convenient and effectively, and makes the cabinet door of rack and cabinet closing seam performance good, has good dust-proof and certain effectiveness; Handsome in appearance, simple for structure, easy to operate, motion is reliable, can realize multi-point fastening, and it is cheap, is easy to promote.
Another object of the present invention is to solve rack cabinet door when being in closed condition, the problem that the handle of door lock can not lock.
Above-mentioned purpose of the present invention is achieved in that provides a kind of gate lock for cabinet of communication equipment, comprise lock box, the bracing frame that connects as one with lock box, be provided with the different chute of direction in the support frame as described above, in described chute, be provided with, can be with on the cabinet door multi-point fastening, following locking bar and horizontal snap close, it is characterized in that, on described, following locking bar and horizontal snap close can carry out linear telescopic and move, in support frame as described above, be provided with can promote described on, following locking bar and laterally snap close move to and stretch out or the crank and the slide block of indentation state, the handle that is rotationally connected with described lock box, the L-shaped structure of described handle, an end of handle is connected in crank and slide block a bit by connecting pin.
Also being provided with in the described lock box can be with the locking device of described handlebar locked in described lock box inner chamber.
Adopt gate lock for cabinet of communication equipment of the present invention, be arranged in the lock box on, following locking bar, laterally the mobile of snap close is that a kind of linear telescopic moves, the space of shared cabinet is little, on the upper and lower side frame and side frame that the upper and lower side frame and the side frame of cabinet door can be locked in cabinet, realized the multi-point fastening of cabinet door and cabinet, guaranteed the closing seam performance of cabinet door and cabinet, have good dust-proof and effectiveness, the handlebar locked device can make door lock when being in the lock state, be not easy to be opened by the inoperative personnel, make the facility work in the rack safer, the profile of door lock is more attractive in appearance.
