Description

Technical Field

[0001] The invention relates to the technical field of high-voltage switches, and in particular to a 10KV pole-mounted switch locking mechanism. Background Art

[0002] At present, the overhead line distribution network switch equipment mainly involves pole switches such as pole load switches, pole circuit breakers, and disconnectors. The pole switches generally use spring operating mechanisms. One is an electric button-type opening and closing button, which is electrically operated by the switch device, and the other is a mechanical closing rod, which is manually opened and closed. The two switches are linked to each other. The closing rod of the pole switch is set on the side of one side of the switch box body. The staff is easy to touch the opening and closing buttons during operation. At the same time, since the mechanical closing rod has no locking mechanism, when the staff operates the opening and closing closing rod again, it is easy to cause misoperation. In addition, the existing pole switches need to be used outdoors for a long time, which is easy to cause the switches to rust or be damaged. There are many types of switches on the working poles, and the operation methods are also different. The staff needs to open and close according to the type of switch. When the staff operates, it is easy to cause the knife switch to be opened and closed in place, or misoperation; therefore, it is very necessary to provide a 10kV pole switch locking mechanism with protective effect, high safety performance, and good locking effect. Summary of the invention

[0005] There are two fixed arms, and the two fixed arms have the same structure and are symmetrically arranged on both sides of the device body.

[0006] The snap-fit ​​buckle comprises a short side, a long side and a hinge axis. The short side and the long side are arranged in a U shape, and the hinge axis is arranged on the short side.

[0007] The upper baffle and the lower baffle are both arc-shaped structures, and the lower baffle is fixed to the upper baffle by a fixing bolt B. A limiting ring is arranged below the fixing bolt B, and the limiting ring is arranged on the lower side of the lower baffle.

[0008] The width of the protrusion is greater than the width at the exit of the fixing arm hole, so that the fixing arm can move in the fixing arm hole without falling off from the fixing arm hole.

[0009] A rubber pad is fixedly arranged at the front end of the lower baffle plate, and the width of the rubber pad is 5-10mm.

[0010] The beneficial effects of the present invention are as follows: the present invention arranges the fixing part in the through holes at both ends of the switch, and by adjusting the rotating pin, the rotating pin drives the gear to rotate, so that the rack and the left and right baffles move outward or inward, so that through holes of different diameters can be applied. At the same time, the snap buckle arranged on the fixed arm can be fixed to the switch body. First, the snap buckle is pulled up and is in a vertical state with the fixed arm. After the fixed arm and the switch body are installed, the snap buckle is lowered to keep the switch body and the fixed arm fixed. At the same time, the upper baffle and the lower baffle on the support plate are arranged in the middle of the device body, which can cover the rotating shaft of the opening device, effectively forming a protective cover, playing a role in preventing rainwater from entering, and preventing the switch rotating shaft from rusting and being difficult to operate. At the same time, the lower baffle is adjustable and can be applicable to a variety of switch devices of different models and widths. The rubber pad at the front end of the lower baffle can play a role in good contact sealing effect and increase friction. The present invention has the advantages of having a protective effect, high safety performance and good locking effect. BRIEF DESCRIPTION OF THE DRAWINGS
