Abstract

The invention discloses a low pressure air switch sleeve lock, which particularly can lock a separating and closing button of a single air switch. The low pressure air switch sleeve lock consists of an inner cuboid bottomless box and an outer cuboid bottomless box which are embedded and sleeved; the side walls of the two boxes are tightly combined and can freely slide; clamping knobs arranged on two sides of the outer box pass through inner box reserved holes to enter the inner wall of the inner box; the clamping knobs correspond to air switch manufacturing holes; and the tops of the inner and outer boxes are provided with a key hole. When the air switch is required to be locked, the sleeve lock is sleeved, the clamping knobs of the outer box are clamped into the switch manufacturing holes for locking; and when the air switch is required to be turned on, a key is inserted into the tops of the boxes, rotated, and pulled out in the direction opposite to the sleeving direction to drive the wall of the inner box of the sleeve lock to slide and push the clamping knobs on the wall of the outer box out of the air switch manufacturing holes so as to turn on the air switch.

Description

A kind of low-voltage air switch lock set

Affiliated technical field:

The present invention relates to a kind of low-voltage air switch lock set, especially can realize deciliter ammonium button, the function of carrying out locking single air switch.

Background technology:

At present, low-voltage air switch is widely used in industrial low-voltage power distribution box, the dwelling building unit resident centralized power distribution case, when need install the electric equipment of distribution box load side, when debugging, the back operation normally has a power failure, need press the low-voltage air switch button implements to have a power failure, when the working site personnel are assorted, 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, prevent misoperation, more time-consuming.

Summary of the invention:

For prevent air switch under off-state by misoperation, increase work efficiency simultaneously, the invention provides a kind of low-voltage air switch lock set, when the staff need be in load side power failure work, only need deciliter ammonium button of air switch under the first ammonium, implement to have a power failure, put this lock set again, just can cover air switch deciliter ammonium button, play the effect that prevents misoperation and switch on.Behind end-of-job, as long as open with private key.

The present invention solves the scheme that its problem adopts: do not have the plastic casing of the no end that is with another in the end plastic casing at a cuboid, two box sidewalls are in conjunction with tight, only leave the gap that can be free to slide, the inner box height is lower than outer box height, respectively there are two pieces of card buttons outer box both sides, this card button passes the corresponding preformed hole position of inner box both sides, the advance by leaps and bounds inwall of inner box, this card button has also limited inner box and has skidded off outer box, the double-deck lock set that formation combines, the position of this card button is corresponding with the manufacturing hole position of air switch both sides; The keyhole that one correspondence is respectively arranged on the inner and outer box end face.When needs locking air switch, only need to put this bilayer lock set to the air switch top, four pieces of card buttons of outer box just stick in the manufacturing hole position of air switch both sides, make this lock set be in non-return state, cover air switch deciliter ammonium button, play preventing that switch is by the effect of malfunction.When needs are opened, only need to go into and twist key from the box tip cutting, spur to the opposite direction of being inserted in again, the end face of inner box is outwards box top operation just, drive lock set inner box wall and slide, the inner box wall has just been realized the unlatching to double-deck lock set with the manufacturing hole of four pieces of card buttons release air switches on the outer box wall.

The invention has the beneficial effects as follows, can effectively prevent the misoperation of air switch, simple in structure.

The present invention is further described below in conjunction with accompanying drawing and example.

Fig. 1 is a structure chart of the present invention.

Fig. 2 is the instance graph that the present invention realizes its function.

1. cuboids do not have the outer box of end plastic casing among the figure, and 2. cuboid does not have end plastic casing inner box, the card button of 3. outer box both sides, the 4. corresponding preformed hole position of inner box both sides, 5. the manufacturing hole position of air switch both sides, 6. keyhole, 7. key, 8. air switch top, 9. lock set inner box wall, 10. air switch.

Embodiment:

In Fig. 1, be with another plastic casing of the no end (2) in a cuboid does not have end plastic casing (1), two box sidewalls only leave the gap that can be free to slide, and respectively there are two pieces of card buttons (3) outer box (1) both sides, card button (3) passes the preformed hole position (4) of inner box both sides, the inwall of the inner box of advancing by leaps and bounds (2).Card button (3) has limited inner box (2) and has skidded off outer box (1), forms the double-decker that combines, and the position of card button (3) is corresponding with the manufacturing hole position (5) of air switch (10) both sides; The keyhole (6) that one correspondence is respectively arranged on inner box (2) and outer box (1) end face.

In Fig. 2, when needs locking air switch (10), only need to put this double-deck lock set to air switch (10) top (8), four pieces of card buttons (3) of outer box (1) just stick into the manufacturing hole position (5) of air switch (10) both sides, card button (3) is in the check position, double-deck lock set just is fixed on the air switch (10), covers air switch (10) deciliter ammonium button.When needs are opened, only need to insert and twisting key (7) from box top keyhole (6), again to the opposite direction pulling of being inserted in, inner box (2) end face is outwards box (1) end face slip just, the inner box wall (9) that drives double-deck lock set slides, inner box wall (9) is removed the non-return state of card button (3) with the manufacturing hole (5) of the release air switches of the four pieces of card buttons (3) on the outer box wall (10), has just realized unlatching.

Claims

1. low-voltage air switch lock set.It is characterized in that: do not have end box by the cuboid of inside and outside two edge covers and form, two box sidewalls are in conjunction with tight, inner box (2) highly is lower than outer box (1) highly, inner box (2) is free to slide in the box (1) outside and suitable stroke is arranged, outer box (1) both sides have card button (3) to pass the advance by leaps and bounds inwall of inner box (2) of inner box (2) preformed hole (4), there is keyhole (6) on inside and outside box top, is furnished with corresponding key (7).
