Description
Technical field
The utility model relates to a kind of communication equipment auxiliary device, especially a kind of distribution two-way in communications equipment room
The locking device for for conducting, specifically a kind of power distribution cabinet interlock.
Background technique
Currently, communication is substantially with power distribution cabinet using duplex feeding, and enter line side is fitted with greatly 2 masters in cabinet
Distributor breaker.It is typically necessary installation interlock between two breakers, to prevent duplex feeding from simultaneously turning on.The biography
The characteristics of interlock of system is can only to limit all the way for conducting, and another way must be obstructed.But tradition interlocking dress
Typically more complexity is set, or does not have locking structure, anyone can operate the interlock, and safety is inadequate
It is high.
Summary of the invention
The purpose of the utility model is to provide a kind of power distribution cabinet interlocks, can effectively overcome the prior art not
Foot, while guaranteeing interlocking, structure is more simple and reliable, moreover it is possible to greatly improve security performance.
The technical solution of the utility model is:
A kind of power distribution cabinet interlock, including backboard, and be mounted on the backboard and slidably limit slide arm；Institute
The middle part for stating backboard is equipped with 1 strip limit hole, the right and left is respectively equipped with 1 flat sliding guide groove notch；It is described
Limit slide arm is strip, is installed in the limit hole and sliding guide groove notch of the backboard, and can horizontally slip.
Further, the backboard is additionally provided with 1 lockhole (as main lockhole), and the limit slide arm, which is equipped with 2, can be used for
The lockhole of padlock locking (as secondary lockhole)；When limit slide arm horizontally slip and after make that wherein 1 secondary lockhole is aligned with main lockhole,
Major and minor lockhole can be passed through with lockset to lock the limit slide arm, irrelevant personnel cannot grasp interlock after locking
Make.
Further, the middle part of the limit slide arm is equipped with a pull rod, limit slide arm is stirred for left and right, with realization pair
1 in 2 breakers carries out limitation opening operation.
Further, the upper and lower parts of the backboard are respectively equipped with 1 installation screw hole, for fixing interlock
It is connected between 2 breakers.
The utility model has the beneficial effects that
The utility model is designed reasonably, it is easy to use, it can be realized to being interlocked, effectively prevent in the case of supplying power with double circuit
Duplex feeding is interconnected, and not only structure is simpler reliable, low in cost, but also can be locked by additional padlock come substantially
Improve security performance.
Detailed description of the invention

Fig. 2 is the application schematic diagram of the utility model.
Wherein: 1- backboard；2- sliding guide groove notch；3- limits slide arm；4- pull rod；5- limit hole；6- slide arm lockhole；7- back
Plate lockhole；8- installs screw hole；9- power distribution cabinet interlock；10- breaker of plastic casing.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
It as shown in Figs. 1-2, is one embodiment of the utility model.
A kind of power distribution cabinet interlock, including backboard, and be mounted on the backboard and slidably limit slide arm；Institute
The middle part for stating backboard is equipped with 1 strip limit hole, the right and left is respectively equipped with 1 flat sliding guide groove notch；It is described
Limit slide arm is strip, is installed in the limit hole and sliding guide groove notch of the backboard, and can horizontally slip.The limit
The middle part of slide arm is equipped with a pull rod, stirs limit slide arm for left and right, is limited with realizing 1 in 2 breakers
Opening operation, that is, when limit slide arm is moved to the left and is limited hole up to round pull rod and blocks, the left end for limiting slide arm can
The switch on the breaker of left side is blocked, its movement is prevented.Reverse movement.
The backboard 1 can be rectangle, and be made of the steel plate of 2mm, and made of the techniques such as punching, jet-bedding, bending
It forms.The limit slide arm is strip, and 2mm steel plate can also be used and be made, and length is greater than carapace length, and wherein
Portion is equipped with 2 strip limit holes.The middle part of the limit slide arm is equipped with 1 screw hole for fixing 1 round pull rod.First will
Limit slide arm is placed into 2 sliding guide groove notches of backboard, then will make to be screwed between round pull rod and limit slide arm,
After fixing, limit slide arm will not fall off from the notch of backboard, and can move left and right certain position.
The backboard is equipped with 1 lockhole (as main lockhole), and the limit slide arm is equipped with 2 locks that can be used for padlock locking
Hole (as secondary lockhole)；It horizontally slips after make that wherein 1 secondary lockhole is aligned with main lockhole, can be passed through with lockset when limiting slide arm
Major and minor lockhole locks the limit slide arm, and irrelevant personnel cannot operate interlock after locking.
It is greater than in use, the distance between breaker being installed in power distribution cabinet, and ensures 2 circuit breakers upper switch
Limit slide wall length 3-5mm.Then, backboard is mounted between 2 breakers by the way of bridging.When needing to limit one
When road powers, the pull rod on limit slide arm is pulled, makes to limit slide arm to side movement, until being blocked by pull rod.At this point, limit is slided
One end of arm can extend to the below or above of side killer switch, this is prevented to close the switch, to ensure all the way for conducting
State.Under each above-mentioned state, a secondary lockhole can be aligned with main lockhole, and install lockset additional on it as hung
Lock keeps limit slide arm immovable, to can greatly improve safety.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
