Description
Technical field
The present invention relates to a kind of technical field of electric equipment, more particularly to a kind of electric handle of anti-dislocation.
Background technology
The transmission or not of low-voltage distribution room is an essential operation in the industrial production, and this work is repeatedly numerous
It is trivial, something event often occurs in operation process.These accidents are roughly divided into two major classes.First, (on-load is drawn wrong diagnosis electricity
Lock), the device powers down that mistake will be currently running causes production equipment to shut down suddenly, causes production accident.And on-load is operated a switch process
In easily there is phenomenon of arc discharge, easily occur operating personnel's flash burn electric shock accidents.Second, misdelivery electricity, will shut down or is examining by mistake
Equipment power transmission in repairing, causes operating personnel to get an electric shock or production accident.In order to prevent the generation of both the above accident, from personnel behaviour
Make to have carried out specification in terms of behavior, formulated the hang-label system of locking of transmission or not.But above-mentioned system is for equipment (handle) sheet
Body does not have the effective precautionary measures but, if handle has higher security in itself, can further improve and electrically set
Security that is standby, being used such as drawout cubicle.
The content of the invention
In order to effectively be taken precautions against in itself for handle, the security of operation is further improved, the present invention is to common behaviour
Transformation has been carried out there is provided a kind of electric handle of anti-dislocation as handle, and the handle can be used on the drawout cubicle in any loop.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of electric handle of anti-dislocation, the handle includes：Shell
Body, top lock, pull bar, magnet coil, spring and top lock shaft, the housing top surface are provided with a top lockhole, and one is provided with sideways
Individual tie rod hole, the enclosure interior is provided with the magnet coil, the spring and the top lock shaft, the magnet coil and institute
State top lock shaft to be fixedly connected with the housing, one end of the pull bar is worn successively from the tie rod hole to the enclosure interior direction
The magnet coil and the spring are crossed, and lower hinge is locked with the top, the other end of the pull bar is located at the tie rod hole
It is interior, and can be stretched out from the tie rod hole outside the housing, one end of the spring is fixedly connected with the magnet coil, the bullet
The other end of spring is fixedly connected with the pull bar, and the top lock shaft passes through the top lock through the top lock middle part, the top lock
Axle and the housing hinge, the top portion of locking are located in the top lockhole, and can be stretched out from the top lockhole outside the housing,
When the magnet coil is powered, the handle is in the lock state, and the pull bar and the top are locked corresponding position and stretched out
Outside the housing, when the magnet coil is powered off, the handle is in released state, and the pull bar and top lock are respectively positioned on
In the housing.
The beneficial effects of the invention are as follows：Handle is divided into lock-out state and released state, and electrical equipment and electromagnetism are corresponded to respectively
The "on" position and off-position of coil, the handle coordinate the electrical equipment such as drawout cubicle in use, can ensure electrically to set
It is standby to be locked when being powered, unlock when power is off, with higher security.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, when the handle is changed into the lock-out state from the released state, the magnet coil obtains electric, institute
State spring to compress to the magnet coil direction, drive the pull bar to be moved through the tie rod hole to the hull outside direction
It is dynamic, while driving the top lock to be moved through the top lockhole to the outside direction of the housing；When the handle is from the lock
When determining state and being changed into the released state, the magnet coil dead electricity, the spring discharges to the magnet coil opposite direction, band
Move the pull bar to move to the enclosure interior direction through the tie rod hole, while driving the top lock through the top lockhole
Moved to the internal direction of the housing.
Beneficial effect using above-mentioned further scheme is：Top lock and pull bar are ejected and taken in simultaneously, make handlebar locked
Process safety with unblock is higher.
Further, when the handle is in the lock-out state, the pull bar can be promoted to pass through the tie rod hole to institute
The internal direction movement of housing is stated, while driving the top lock to be moved through the top lockhole to the internal direction of the housing.
Beneficial effect using above-mentioned further scheme is：If emergency occurs for "on" position, it can still pass through hand
Flowing mode is unlocked to handle, improves the security of operation.
Further, in the control loop of the magnet coil series connection access electrical equipment, when the electrical equipment is powered,
The handle is in the lock-out state, and when the electrically equipment electricity, the handle is in the released state.
Beneficial effect using above-mentioned further scheme is：Otherwise designed circuit is not needed to the automatically controlled of handle, directly connect
Improvement cost can be greatly reduced by entering existing control circuit.
