Abstract
A safety cover for a low-pressure air switch is of a cuboid box structure without a bottom, the size of the inner edge of the box is larger than the size of the top part of the air switch, the inner wall of the box is provided with a plurality of clamping buttons recessing into the box, the positions of the clamping buttons corresponds to manufacturing hole sites on side faces of the air switch, the position of each clamping button is provided with a ring plate which penetrates through the clamping button and is adhered to the inner wall of the box, the box is internally provided with a plate type rectangular block, the plane of the plate type rectangular block is parallel to the plane of the bottom of the box, the distance between the plane of the plate type rectangular block and the plane of the bottom of the box is not less than the length of the clamping buttons, and the plate type rectangular block is connected with the ring plates. The top face of the box and the plate type rectangular block are respectively provided with a key hole. When the safety cover covers the air switch, the clamping buttons on the inner wall of the box are clamped into the manufacturing holes on the side faces of the switch, and the cover is in a non-return state, so that the misoperation is prevented. When the safety cover is opened, a key is inserted and then is pulled after being turned, so that the plate type rectangular block in the box drives the ring plates to extrude the clamping buttons out of the manufacturing holes of the air switch, and thus the opening of the safety cover is realized.
Description
Affiliated technical field:
The utility model relates to a kind of low-voltage air switch safety guard, especially can cover deciliter button of the air switch under the off-state, prevents misoperation.
Background technology:
At present, air switch is widely used in industrial power distribution case, the resident's centralized power distribution case, when need install the electric equipment of distribution box load side, when debugging, usually need press the low-voltage air switch button implements to have a power failure, for prevented the people install, this air switch is switched on by misoperation during debugging, threat to life, therefore general the employing locked distribution chamber door or on-the-spot special messenger guard, and be more time-consuming.
Summary of the invention:
For prevent air switch under off-state by misoperation, increase work efficiency simultaneously, the utility model provides a kind of low-voltage air switch safety guard, when the staff need be in load side power failure work, only need press deciliter button of air switch earlier implements to have a power failure, this safety guard on the air switch main header casing just can cover air switch deciliter button again, prevents the misoperation energising.Behind end-of-job, as long as open with private key.
The scheme that the invention for solving the technical problem adopted is: a cuboid does not have end box structure, this box inner dimensions is greater than the air switch top dimension, make it can cover air switch, but only leave the gap that can be free to slide, this box inwall has card button in some boxes of advancing by leaps and bounds, the position of card button is corresponding with the manufacturing hole position of each side of air switch, on the position of each card button, all there is a ring plate to pass the card button and is close to the box inwall, also has a sheet pane in the box less than inward flange size at the bottom of the box, sheet pane plane in the box is parallel with the box baseplane and the distance that is not less than card button length is arranged, and the edge of sheet pane is connected with ring plate.On the sheet pane in box top and the box, the keyhole of a correspondence is arranged respectively.When needs cover air switch, only need this safety guard on the air switch main header casing, the some card buttons of box inwall just stick in the manufacturing hole position of each side of air switch, make this safety guard be in non-return state, cover air switch deciliter button, play the effect that prevents that switch from being moved by misoperation.When needs are opened, only need to go into and twist key from the box tip cutting, to the opposite direction pulling of being inserted in, the interior sheet pane of box just drives some ring plates and slides along the box inwall again, ring plate is just extruded the card button on the box wall manufacturing hole of air switch, has just realized the unlatching to safety guard.
The beneficial effects of the utility model are, can effectively prevent the misoperation of air switch, and are simple in structure.

Below in conjunction with accompanying drawing and example the utility model is further specified.
1. cuboids do not have end box among the figure, 2. sheet pane in the box less than inward flange size at the bottom of the box, 3. the box inwall card button in the box of advancing by leaps and bounds, 4. pass the ring plate of card button, 5. the manufacturing hole position of air switch both sides, 6. keyhole, 7. key, 8. air switch top, the 9. edge of sheet pane and the brace that links to each other with ring plate, 10. air switch.
Embodiment:
In Fig. 1 to 8, in not having end box (1), a cuboid is with a sheet pane (2) less than box (1) end inward flange size, sheet pane (2) plane is parallel with the box baseplane and the distance that is not less than card button length arranged, box (1) inwall has card button (3) in some boxes of advancing by leaps and bounds, the position of card button (3) is corresponding with the manufacturing hole position (5) of each side of air switch, all have a ring plate (4) to pass card button (3) and be close to box (1) inwall on the position of each card button (3), the edge of sheet pane (2) is connected with ring plate (4) by brace (9).On the sheet pane (2) in box (1) end face and the box, the keyhole (6) of a correspondence is arranged respectively.
In Fig. 6 to 8, when needs cover air switch (10), only need this safety guard on the cover of air switch top (8), the some card buttons of box inwall (3) just stick in the manufacturing hole position (5) of each side of air switch, make this safety guard be in non-return state.When needs are opened, only need to insert key (7) and twisting from box top keyhole (6), again to the opposite direction pulling of being inserted in, sheet pane (2) in the box just drives some ring plates (4) and slides along the box inwall, ring plate is just extruded the card button (3) on the box inwall manufacturing hole (5) of air switch, remove the non-return state of card button (3), just realized unlatching safety guard.
