Further, described fixture is that outer peripheral face is formed with externally threaded cylinder, the pilot hole inwall of described body is formed with the internal thread that cooperates with described fixture external screw thread, and described fixture is fixedly connected in the pilot hole of described body by described internal and external screw thread.

Further, the end face of described fixture is provided with to install and uses handle hole.

Further, the external diameter of the through hole of described fixture and described joystick is suitable.

Further, be formed with the pin-and-hole that laterally runs through joystick on the described other end of described joystick, be equipped with a split pin in the described pin-and-hole.

Further, described control arm one end is formed with an installing hole, and described installing hole is sheathed in the separating brake rotating shaft of described primary cut-out, and is locked by bolt.

Further, described control arm is provided with the handle portion that is oppositely arranged with described joystick, and described handle portion is a platy structure.

The utlity model has following beneficial effect:

When the secondary control loop of switch cubicle breaks down, in the time of need carrying out urgent separating brake to primary cut-out, only need to promote sliding part by the operation hole on the cabinet door, joystick is stretched out and promote the separating brake shaft swing of the handle portion of control arm around primary cut-out, carry out separating brake to drive separating brake rotating shaft rotation, the thrust of cancellation sliding part behind the separating brake, joystick is withdrawn under the effect of spring and is resetted handiness; The utility model is made up of control arm, guiding body, sliding part, fixture, joystick and spring, and above-mentioned each part is all simple in structure, with low cost.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Embodiment

With reference to shown in Figure 1, the urgent switching-off device of a kind of switch cubicle, be installed on the cabinet door 9 of switch cubicle, separating brake rotating shaft 2 rotations that are used to handle primary cut-out are made up of control arm 1, guiding body 4, sliding part 5, fixture 8, joystick 6 and spring 7 to realize separating brake.

Control arm 1 is connected with the separating brake rotating shaft 2 of primary cut-out, be used to drive separating brake rotating shaft 2 and rotate the realization separating brake, concrete connected mode is: control arm 1 one ends are formed with an installing hole 12, installing hole 12 is sheathed in the separating brake rotating shaft 2 of primary cut-out, and be locked by bolt 13, its other end is formed with a tabular handle portion 11; Guiding body 4 connects vertically and is formed with pilot hole 41, the vertical connection of madial wall of one end and cabinet door 9, offer the handle hole of aiming at pilot hole 91 on the cabinet door 9, and the diameter of handle hole 91 is less than the diameter of pilot hole 41; Sliding part 5 is cylindric insulator, and it is mounted slidably in the close pilot hole 41 of cabinet door 9 one sides; Fixture 8 is a cylinder, its outer peripheral face is formed with external screw thread, pilot hole 41 inwalls away from cabinet door 9 one sides are formed with the internal thread that matches with the external screw thread of fixture 8, fixture is fixedly set in the pilot hole 41 away from cabinet door 8 one sides by internal and external screw thread, the end face of fixture 8 is provided with to be installed with handle hole 81, fixture 8 middle parts offer the through hole 82 that extends along pilot hole 41 length directions, and the diameter of the size of through hole 82 and joystick 6 is suitable; Joystick 6 one ends are fixedlyed connected with sliding part 5, the other end passes the through hole 82 of fixture 8, and can be by handle portion 11 telescopic moving between the primary importance and the second place of the relative control arm 1 of sliding part 5 manipulations, when joystick 6 in primary importance, joystick 6 stretches out and promotes control arm 1 swing and makes the primary cut-out separating brake, when joystick 6 in the second place, joystick 6 withdrawals are in initial position, in order to prevent to come off after joystick 6 from installing, also the end at joystick 6 is provided with a block piece, concrete block piece is split pin 61, and joystick 6 ends are formed with the radial direction through hole (not shown) of passing for split pin 61; Spring 7 is arranged in the pilot hole 41 between sliding part 5 and the fixture 8, is used to make joystick 6 to be in the second place.
