Description

Technical Field

[0001] The utility model belongs to the technical field of locking devices, and in particular relates to a locking device for an electrical control cabinet. Background Art

[0002] The locking device of an electrical control cabinet is usually used to ensure operational safety and prevent unauthorized personnel from misoperating electrical equipment. It is usually a device that can lock the operating handle and panel, making it impossible to open or operate the control cabinet without the appropriate key and password. Traditional locking devices use a single locking method, which makes the closing safety of the electrical control cabinet low, thereby reducing the safety of the electrical control cabinet when closed. Therefore, a locking device for an electrical control cabinet is proposed.

[0003] For example, the Chinese patent publication number CN210274803U discloses a locking device for an electrical control cabinet. The electrical control cabinet includes a cabinet body and an inner cabinet box. The inner cabinet box is installed in the cabinet body. The electrical control cabinet is provided with a side locking device. The side locking device includes a limiting groove provided in the cabinet body and a rear convex strip provided in the inner cabinet box. The rear convex strip is engaged in the limiting groove to prevent the relative movement between the inner cabinet box and the cabinet body, thereby locking the electrical control cabinet.

[0004] The existing technical documents have the following problems:

[0005] The existing technical documents have some shortcomings in use. For example, the traditional locking device adopts a single locking method, which makes the locking method of the electrical control cabinet single, thereby reducing the stability of the electrical control cabinet when closed. Moreover, if the locking device is operated by non-staff, it can be operated multiple times, which reduces the safety of the locking device. In view of this, we propose a locking device for an electrical control cabinet. Utility Model Content

[0006] The purpose of the present invention is to provide a locking device for an electrical control cabinet in order to solve the above-mentioned technical problems, thereby improving the stability of closing the electrical control cabinet and improving the safety of using the locking device.

[0008] Based on the above structure, when the electrical cabinet is closed, the electrical cabinet is electrically limited by the electric lock, and then the electrical cabinet is limited by the latch. The movable shaft drives the block to limit the latch, and the lock slot is conveniently used to cooperate with the lock head to perform the locking work. Then, the electric telescopic rod is used to lock the latch and the electric lock after the password is entered more than three times, thereby reducing the danger when the locking device is closed.

[0009] Preferably, the surface of the lock head is provided with slots at equal intervals, and screws are installed through the surface of the slots to fix the lock head by means of the screws.

[0010] Preferably, a fixing seat is fixedly installed on the bottom of the lock seat, and a fixing bolt is installed through the surface of the fixing seat, and the lock seat is installed by using the fixing bolt.

[0011] Preferably, a hinge is fixedly mounted on the surface of the cabinet body, and a cabinet door is fixedly mounted on the surface of the hinge, so that the cabinet body is used to install and connect the hinge.

[0012] Preferably, a sealing sleeve is sleeved on the surface of the cabinet door, and the sealing sleeve is made of rubber material, and the sealing sleeve is used to increase the sealing performance of the cabinet door.
