Problems solved by technology
[0004] In order to overcome the limitations of the structure of the existing electrical control cabinet, the locks used cannot prevent the relevant personnel from opening the cabinet door when the cabinet is charged, and there are certain safety hazards. In the application, as long as the power input to the electrical control cabinet is not disconnected, the relevant personnel cannot open the cabinet door, and the cabinet door can only be opened after a power failure, which effectively prevents the risk of electric shock to the relevant personnel caused by live operation, and does not use a key Open and close the cabinet door (there are certain disadvantages in using the key, the key needs to be carried by the relevant personnel, which will bring some inconvenience to the relevant personnel), an electrical and mechanical interlocking device that is more convenient to use

The invention relates to an electrical and mechanical interlocking device comprising a bottom plate, a movable plate, a handle plate and a linkage plate. A fixed plate is arranged at the front end ofthe bottom plate, a through hole is formed in one end of the fixing plate, and a guide rod is arranged on the side of the through hole. The movable plate is provided with a plurality of guide grooves,and a limiting rod is arranged on one inner side of one guide groove; an electromagnet is mounted at one end of the fixed plate; the movable plate is positioned on the front side of the fixed plate;an armature rod of the electromagnet is positioned in the other side of one guide groove of the movable plate; a through hole is formed in the rear side end of an armature rod of the electromagnet; aclamp groove is formed in the front of the through hole; a shaft rod is arranged at the upper part of the bottom plate; a middle shaft hole of the linkage plate is formed in the outer side of the shaft rod in a sleeving manner; the handle plate is provided with a shaft hole, and the handle plate shaft hole is hinged to one side of the linkage plate. The fixing plate is installed on one side in anelectrical control cabinet, and the front end of the handle plate is located outside the electrical control cabinet. According to the invention, the electric shock risk brought to related personnel bylive-line operation is prevented, a key switch is not adopted, and the use is more convenient. Therefore, the device has a good application prospect.
Description
technical field [0001] The invention relates to the technical field of electrical control cabinet supporting equipment, in particular to an electrical and mechanical interlocking device. Background technique [0002] The electrical control cabinet is a kind of equipment widely used in the field of electricity consumption and power supply. Various control switches, circuit breakers, electrical monitoring equipment, etc. are installed inside it. In order to facilitate the operation of the electrical equipment in the electrical control cabinet and to read the data displayed by the relevant monitoring equipment, the electrical control cabinet is equipped with a movable door. In order to prevent unrelated personnel from opening the movable door, the existing electrical control cabinets are equipped with various locks. [0003] At present, the locks used in electrical control cabinets are generally mechanical locks such as padlocks and built-in locks. Although they can prevent key...
