Problems solved by technology
[0003] For this reason, the technical problem to be solved by the present invention is that the locking device for the control line plug of the switch cabinet handcart in the prior art cannot lock the control line plug in the middle position between the experimental position and the working position, and may cause errors. For operational problems, provide a locking device for the switch cabinet handcart control line plug that can also be locked in the middle position between the test position and the working position

The invention relates to a handcart control wire plug latching device for a switch cabinet, which comprises a latching mechanism for preventing a control wire plug from being pulled out of a socket and a driving mechanism for driving the latching mechanism to open or latch, wherein the latching mechanism comprises a mounting frame, a rotating frame rotationally arranged on the mounting frame through a rotating shaft and a latching bent rod arranged on the rotating frame; the driving mechanism comprises a push plate and a linkage plate for hinging the push plate to a cabinet body to form a parallel connecting rod structure; and one end of the push plate towards a handcart panel is pushed by the handcart panel to drive the rotating frame to rotate so that the latching bent rod rotates, and the free end of the latching bent rod rotating to a set position is buckled on a connecting handle of the control wire plug in a latching state. The device can latch the control wire plug at a workingposition and a middle position between an experiment position and the working position.
Description
technical field [0001] The invention relates to a locking device on a switch cabinet, in particular to a locking device for a switch cabinet handcart control line plug. Background technique [0002] At present, in the handcart switchgear, most of the handcarts, such as the control line connector parts of the 35kV voltage handcart, are usually installed in a hidden position on the lower side of the cabinet, which is inconvenient to operate due to the narrow space on the lower side of the cabinet. , When the handcart enters and exits the cabinet, it is easy to touch and take the control line plug out of the socket due to negligence, and even cause the pulling damage of the control line connector parts. In order to prevent the control line plug from being pulled out at the working position, it is usually realized by setting a control line plug locking device in the prior art, but the control line plug locking device in the prior art can only realize locking when the handcart is...
