Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to the attached drawings 1-3, the switch cabinet door anti-opening warning mechanism comprises a cabinet body 2 and a cabinet door 1, wherein the cabinet body 2 comprises an upper plate, a lower plate, a left plate, a right plate and a rear plate, a containing space is enclosed, and the cabinet door 1 is located in front of the cabinet body 2. The cabinet door 1 comprises an outer door part 12 and an inner door part 13, a step is formed between the outer door part 12 and the inner door part 13, when the cabinet door 1 is closed, the outer door part 12 is abutted against the outer side surface 24 of the cabinet body facing one side of the cabinet door, and the inner door part 13 is abutted against the inner side surface 25 of the cabinet body. The cabinet door 1 is hinged to the cabinet body 2 and can be opened or closed relative to the cabinet body 2, specifically, one side of the cabinet door 1 is hinged to the cabinet body 2 through a hinge, and the cabinet door 1 can rotate around the hinge point, so that the cabinet door 1 is opened or closed.
The cabinet door 1 is provided with an abutting part 11, and specifically, the abutting part 11 is arranged on the inner door part 13. The abutting piece 11 is convexly arranged towards the cabinet body 2, in this embodiment, the abutting piece 11 is a sheet-shaped structure welded on the inner side of the cabinet door, and the plane of the sheet-shaped structure is parallel to the plane of the cabinet door 1. The cabinet is characterized in that a travel switch 21 is arranged in the cabinet body 2, the outmost side of the travel switch 21 does not protrude out of the outer surface of the cabinet body 2, in the embodiment, the outmost side of the travel switch 21 is located in the cabinet body 2, so that when the cabinet door is opened, the travel switch 21 cannot be exposed out of the cabinet body, and the travel switch is not easy to damage. The travel switch 21 comprises a switch part 22, and when the cabinet door is closed, the abutting piece 11 abuts against the switch part 22 of the travel switch 21; the travel switch 21 is connected to an alarm, which in this embodiment is a buzzer alarm.
In this embodiment, the travel switch 21 is fixed at the upper part in the cabinet body through a bracket 23, and the abutting member 11 is disposed at the inner side of the cabinet door corresponding to the switch part 22 of the travel switch 21. The bracket 23 comprises a first transverse section 231, a second transverse section 232 and a longitudinal section 233, the longitudinal section 233 is connected between the first transverse section 231 and the second transverse section 232, the first transverse section 231 is connected with the upper part in the cabinet body, and the second transverse section 232 is connected with the travel switch 21. The first transverse segment 231 is provided with a through hole 234, and the first transverse segment 231 is locked at the upper part inside the cabinet body 2 through a bolt. The support 23 is locked on the upper portion of the cabinet body through bolts, the upper portion of the cabinet body is provided with more than two groups of bolt holes for locking the support along the direction of the inner side and the outer side of the cabinet body, so that the mounting position of the travel switch 21 can be adjusted, and the matching of the abutting piece 11 and the travel switch 21 is more stable.
According to the switch cabinet door opening prevention warning mechanism, when the cabinet door 1 is in a closed state, the abutting piece 11 abuts against the switch part 22 of the travel switch 21, the travel switch 21 is in the closed state, and at the moment, an alarm electrically connected with the travel switch 21 is not triggered. When the cabinet door 1 is opened by mistake, the abutting piece 11 is far away from the switch part 22, and the travel switch 21 is triggered to be converted into an opening state from a closing state, so that an alarm is triggered, and an alarm is given to remind an operator to prohibit operation. If normal maintenance needs operating personnel earlier with cubical switchboard outage, the electric connection between travel switch 21 and the siren is cut off, opens the cabinet door this moment and just can not send the police dispatch newspaper, just can normally maintain. The opening prevention warning mechanism can avoid the misoperation of opening the cabinet door, thereby reducing the occurrence of accidents.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
