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

Embodiment Construction
[0032] like Figure 1 to Figure 6 As shown, a switchgear handcart control wire plug locking device in the first embodiment includes a locking mechanism for preventing the control wire plug 13 from being pulled out of the socket and a driving mechanism for driving the locking mechanism to open or lock, wherein
[0033] The locking mechanism includes an installation frame 1, a turret 3, and a locking bending rod 5. The installation frame 1 is fixed on the cabinet body; the turret 3 is rotatably arranged on the installation frame 1 through the rotating shaft 2 , and is subjected to a biasing force that tends to the first position of the turret; one end of the locking bending rod 5 is a free end, and the other end is a fixed end, and the locking bending rod 5 is fixed at the fixed end through the fixed end. on the turret 3, and can rotate around the rotating shaft 2 with the turret 3;
[0034] The drive mechanism includes a push plate 9 and a linkage plate 8, the push plate 9 is ...

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 working position 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 plug locking device for a handcart control line in a switch cabinet. Background technique [0002] At present, in the handcart-type switchgear, most handcarts, such as the handcart with a voltage level of 35kV, are usually installed in a concealed position on the underside of the cabinet, which is inconvenient to operate due to the narrow space on the underside of the cabinet. , When the handcart enters and leaves the cabinet, it is easy to touch and take the control wire plug out of the socket due to negligence, and even cause the pulling and damage of the control wire plug-in parts. In order to prevent the control wire plug from being pulled out when it is in the working position, it is usually realized by setting the control wire plug locking device in the prior art, but the control wire plug locking device in the prior art can only realize the locking when the handcar...
