Embodiment 2

[0031] The second embodiment of a switchgear of the present invention differs from the first embodiment in that the end of the deadbolt that cooperates with the unlocking push rod may not be an arc structure, and may also be set as a wedge structure. At this time, the end of the push rod The middle plate is also provided with a matching wedge surface structure.

Embodiment 3

[0032] The third embodiment of a switchgear of the present invention differs from the first embodiment in that the number of spring connection holes on the bolt can also be adjusted according to actual needs, for example, one or three.

[0033] The fourth embodiment of a switchgear of the present invention differs from the first embodiment in that there may be only one connecting plate, and at this time there is only one valve and it is connected to the connecting plate, and at this time there is only one The tongue groove is enough.

Embodiment 5

[0034] The fifth embodiment of a switchgear of the present invention is different from the first embodiment in that the pushing part of the middle plate and the pushing part of the side plate can also be formed by correspondingly welded cylinders or round tubes.

[0035] Embodiment 6 of a switchgear of the present invention is different from Embodiment 1 in that the structure of the lock tongue is different. The lock tongue includes a push arm and a lock arm, and the length of the push arm is greater than the length of the lock arm. When the unlocking push rod and the push arm push, the locking arm can be driven to separate from the draw-in groove, and at this moment, no groove is arranged on the dead bolt.

Abstract

The invention relates to a switch cabinet and a valve driving mechanism with a self-locking function thereof. The valve driving mechanism comprises a mounting frame and a connecting plate rotationallymounted on the mounting frame; the valve driving mechanism further comprises a spring bolt which is movably assembled on the mounting frame, wherein the guiding direction of the spring bolt is parallel to the rotating axis of the connecting plate. A lock hole structure is arranged on the connecting plate, and the spring bolt is provided with a locking position connected with the lock hole structure in an inserted mode and an unlocking position separated from the lock hole structure in the moving stroke of the spring bolt, wherein a reset spring is arranged between the spring bolt and the mounting frame, and the spring bolt is provided with a pushing part used for being pushed by a corresponding unlocking push rod to overcome an acting force of a reset spring to move towards the unlockingposition. During use, the unlocking push rod pushes the spring bolt, so that the spring bolt moves to the unlocking position along the guide direction of the mounting frame; at the moment, the springbolt unlocks the connecting plate, the connecting plate can rotate to drive a valve to be opened, the unlocking push rod to move reversely and the valve to be closed; meanwhile, the spring bolt is guided to move to the locking position under the action of the reset spring, the connecting plate is locked and cannot rotate at the moment, and the valve self-locking effect is achieved.

Description

[0001] This application is a divisional application of the following application, the filing date of the original application: May 10, 2017, the application number of the original application: 201710326132.7, the title of the invention of the original application: a switch cabinet and its self-locking valve Drive mechanism. technical field [0002] The invention relates to a switch cabinet and a shutter driving mechanism with self-locking function. Background technique [0003] Among power system products, high-voltage switchgear is one of the important equipment. In the switchgear, the handcart type circuit breaker is the most widely used circuit breaker. The handcart is equipped with moving contacts, and the static contacts are installed in the switchgear and connected to the high-voltage line. Pushing or pulling the handcart To realize the connection or disconnection of the moving contact and the static contact, and then realize the connection or disconnection of the cir...
