According to the attached drawings 2-3, the outside of the lock main body 2 in the device is provided with the protection mechanism 3, the protection mechanism 3 is arranged on one side of one group of cabinet doors 101, one end of the protection mechanism extending to the other group of cabinet doors 101 is only contacted with the surface of the other group of cabinet doors 101, the one group of cabinet doors 101 provided with the protection mechanism 3 can be opened before the cabinet doors 101 are opened, the protection mechanism 3 comprises a fixed seat 301 and a protection shell 302, one side of one group of cabinet doors 101 is provided with the fixed seat 301, the two groups of fixed seats 301 are positioned at the upper end and the lower end of the lock main body 2, the protection shell 302 is arranged between the two groups of fixed seats 301 in a sliding manner, the protection shell 302 is protected on the outer surface of the lock main body 2, because the lock main body 2 is made of metal, and the box-type switch cabinet main body 1 is generally arranged outdoors, so that the lock main body 2 is easily affected by natural factors to generate corrosion, and the service life of the lock main body 2 is reduced.

According to the attached drawings 3-4, the upper surface and the lower surface of the protective shell 302 in the device are fixedly provided with limiting blocks 303, the two groups of limiting blocks 303 respectively slide in the fixed seats 301 in a limiting manner, one sides of the two groups of fixed seats 301, which are close to the protective shell 302, are provided with sliding ways 305 for limiting the sliding of the limiting blocks 303, one end upper surfaces of the fixed seats 301 are provided with threaded rods 306, one end threads of the threaded rods 306 are inserted in the limiting blocks 303, the outer surfaces of the limiting blocks 303 are provided with holes 304, one end threads of the threaded rods 306 are inserted in the holes 304, when the threaded rods 306 are inserted in the holes 304 formed in the limiting blocks 303, the protective shell 302 is protected outside the lock body 2 at the moment, and the corrosion damage of natural factors such as rainwater to the lock body 2 can be prevented.

According to fig. 4, an expansion link 307 is arranged between the inner side wall of the slide 305 and the limiting block 303 in the device, a spring 308 is arranged on the outer surface of the expansion link 307 and used for automatic resetting of the protective shell 302, one end of the spring 308 is connected with one end side of the expansion link 307, the other end of the spring 308 is connected with the inner side wall of the slide 305, the diameters of two groups of rod bodies forming the expansion link 307 are different, one end of the spring 308 is fixedly arranged on the side face of a group of rod bodies with a larger diameter, after the threaded rod 306 is separated from the limiting block 303, the protective shell 302 is in a movable state at the moment, and the protective shell 302 is gradually increased under the elastic action of the spring 308, so that the protective shell 302 slides towards one end of the fixing seat 301 far away from the threaded rod 306, and further the lock body 2 arranged on the side face of the cabinet door 101 is exposed.

The working principle is as follows:

during initial state, the limiting block 303 that protective housing 302 upper and lower surface set up is located the inside one end of keeping away from threaded rod 306 of fixing base 301, and protective housing 302 does not contact between this moment and the tool to lock main part 2, and tool to lock main part 2 is in the state of exposing.

This novel mechanical locking device of box cubical switchboard is when using, at first operating personnel carry out the unblock operation through corresponding key to the tool to lock main part 2 that this cabinet door 101 department set up, then can open earlier a set of cabinet door 101 that sets up to protective housing 302 another a set of cabinet door 101 opening earlier for the inside of cubical switchboard main part 1 exposes, thereby can carry out corresponding operation to the electrical equipment of its inside setting.

Further, when needing to carry out the shutting operation to cubical switchboard main part 1, can close two sets of cabinet doors 101 earlier, then carry out the shutting operation to the tool to lock main part 2 that this cabinet door 101 department set up through corresponding key again for cubical switchboard main part 1 is whole in encapsulated situation.

Further, when the lock body 2 is in a locked state, the protective shell 302 can slide in a direction close to the lock body 2, at this time, the limiting blocks 303 arranged on the upper and lower surfaces of the protective shell 302 slide along the slide ways 305 arranged inside the fixing base 301 to the end of the fixing base 301 provided with the threaded rod 306, and at this time, the telescopic rods 307 and the springs 308 arranged between the limiting blocks 303 and the slide ways 305 gradually extend.

Further, after the limiting block 303 offsets with the one end side wall of the fixing seat 301 where the threaded rod 306 is disposed, the protective shell 302 is completely sleeved on the outer surface of the lock main body 2 to perform the protection operation on the outer surface, and then the threaded rod 306 disposed at the fixing seat 301 can be rotated, so that the one end thread of the threaded rod 306 is inserted into the hole 304 formed inside the limiting block 303, and the protective shell 302 is stably disposed outside the lock main body 2.

Finally, when the lock main body 2 needs to be unlocked, the threaded rod 306 is rotated, so that the threaded rod 306 is separated from the limiting block 303, the fixing effect of the protective shell 302 provided with the limiting block 303 disappears, the elastic effect of the spring 308 on the protective shell 302 is gradually increased, the protective shell 302 slides towards one end of the fixing seat 301 far away from the threaded rod 306, and the lock main body 2 arranged on the side face of the cabinet door 101 is exposed, so that unlocking operation is performed.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
