In order to achieve the above object, the utility model adopts the following technical solutions: a locking box for preventing misuse, including a base and a cover buckled on the base, and the cover is provided with a door that can be opened from the outside of the cover. Locking mechanism, one edge of the box cover is provided with outwardly protruding fixed teeth, and the inner side of the base is provided with a groove capable of accommodating the fixed teeth at a position corresponding to the fixed teeth, and the fixed teeth extend into the corresponding grooves And at the same time cooperate with the locking mechanism to fix the box cover on the base. When in use, the base is fixed on the panel at the operating handle so that the handle is surrounded by the base, and the box cover is fastened on the base through the cooperation of the fixing teeth and the locking mechanism. At this time, the operating handle is completely covered by the operating handle. Inside the locking box; when it is necessary to switch the equipment, use the key to open the locking mechanism, and remove the box cover to operate the operating handle.

As a further improvement, the locking mechanism includes a lock tongue that is pushed by a spring and protrudes from the edge of the box cover, and the base is provided with a groove capable of accommodating the end of the lock tongue; the box cover is provided with a The unlocking hole through which the key passes, a shifting block that can cooperate with the end of the key is provided in the unlocking hole, and a semicircular pushing block that can push the dead bolt backward is provided at the lower end of the shifting block. When locking, the end of the bolt is pushed by the spring to fit into the groove at the corresponding position on the base, and at the same time cooperate with the fixed teeth on the cover to lock the cover on the base; when unlocking, use the key to drive the dial to rotate and push at the same time The block rotates, pushes the lock tongue backward, the lock tongue retracts, and the end of the lock tongue withdraws from the corresponding groove, and at this time the lid can be taken off from the base.

As a further improvement, the lid and the base are connected by a connecting device. The connecting device can connect the box cover and the base together to facilitate the installation of the box cover.

As a further preference, the connecting device is a connecting chain or a connecting rope. This solution is easier to implement and has a lower cost.

As a further improvement, an RFID (Radio Frequency Identification) chip is arranged inside the box cover. After adopting the technical scheme, it can cooperate with the special electronic unlocking device to unlock.

As a further improvement, the box cover is provided with a slot for placing a label. After the label placement slot is set, the relevant description or identification of each switch can be placed in it, so as to facilitate the identification of the operator.

The beneficial effects of the utility model are: the locking box of the utility model locks the lock operation handle in the box through the base and the box cover, and the special key needs to be used to unlock and open the box cover when switching the equipment, which can effectively prevent misoperation , avoiding damage to the control loop and ensuring equipment safety.
