Abstract
The utility model discloses a switch lock for an explosion-proof electric appliance. The switch lock comprises a handle cover casing and a lock pin cover casing, wherein the handle cover casing is provided with notches, and the notches clamp a handle; the lock pin cover casing is fixedly connected with the handle cover casing and is provided with an opening; a connection rod passes through the opening, and the connection rod tightly locks a lock pin; and a bottom end of the connection rod is provided with a lock hole. According to the switch lock for the explosion-proof electric appliance, the handle is covered by the handle cover casing, the notches on the handle cover casing clamp the handle, and the bottom end of the connection rod passing through the lock pin cover casing is provided with the lock hole, so that a lock can be latched in the lock hole. Only after a worker who manages the electric appliance opens the lock with a key, the handle can be pulled, and an electric appliance switch is activated. Thus, others are prevented from carrying out maloperation of the electric appliance, and on-site production security is improved.
Description
Technical field
The utility model relates to mine power supply safe practice, relates in particular to a kind of explosion-proof electric apparatus switch lock.
Background technology
In the down-hole of coal mining, multiple explosion-proof electric equipments are set conventionally, these equipment need deploy switch locking device.
Existing latching device for switch drives lock pin movement by swing handle, thereby realizes locking and open.But there is the possibility of misoperation in this locking form, once non-electrician's personnel encounter handle because of carelessness, lock is opened, there is the situation that misdelivery is electric, can make the personnel of work on the spot cause danger.
Utility model content
The utility model provides a kind of explosion-proof electric apparatus switch lock, to solve the problems of the prior art, avoids misoperation.
The utility model provides a kind of explosion-proof electric apparatus switch lock, wherein, comprising:
Handle case, offers breach on described handle case, and described breach is stuck on handle;
Lock pin case, is fixedly connected with described handle case, on described lock pin case, offers perforate, in described perforate, is equipped with connecting rod, and described connecting rod clamping lock pin; The bottom of described connecting rod is provided with lockhole.
Explosion-proof electric apparatus switch lock as above, wherein, preferably: described connecting rod is screw rod, and the first end of described screw rod is provided with nut, the second end of described screw rod arranges described lockhole.
Explosion-proof electric apparatus switch lock as above, wherein, preferably: the aperture of described lockhole is 4-4.2mm.
Explosion-proof electric apparatus switch lock as above, wherein, preferably: described handle case and described lock pin case are for being welded and fixed.
Explosion-proof electric apparatus switch lock as above, wherein, preferably: the screw rod that described screw rod is M12.
Explosion-proof electric apparatus switch lock as above, wherein, preferably: the length of described screw rod is 85-90mm.
The explosion-proof electric apparatus switch lock that the utility model provides covers handle by handle case is set, and simultaneously the breach on handle case blocks handle, and the connecting rod bottom wearing on lock pin case arranges lockhole, in lockhole, will lock pinning.If only have the staff of this electrical equipment of management with opening after lock, ability pulling handle, starts appliance switch.Therefore, avoid other people misoperation to electric equipment, improved the fail safe of produced on-site.
