A kind of air switch locking device
Technical field
The present invention relates to a kind of locking device, especially relate to a kind of air switch locking device.
Background technology
Enterprise produces safety is more and more paid attention to now, take the generation of many kinds of measures prevention security incident, especially at electrical maintenance work, more pay attention to strick precaution and the management of safety utilization of electric power, while requiring maintenance, want power-off, list, lock etc., to guarantee that the safety of maintenance work carries out.In the power-off of when maintenance, listing is easy to accomplish, but lock, does not accomplish, because condition is difficult, meets, have no idea to lock, because there is no locking mechanism on air switch.
As depicted in figs. 1 and 2, the external accessory of existing air switch mainly comprises air switch box 1 and deciliter operating grip 2.Whole air switch does not arrange locking mechanism.
Summary of the invention
The present invention has designed a kind of air switch locking device, and the technical problem of its solution is that existing air switch does not arrange locking mechanism, may have potential security risk.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
An air switch locking device, comprises air switch box (1) and deciliter operating grip (2), and described deciliter operating grip (2) carries out position restriction by a locking device and described air switch box (1).
Further, described locking device mainly comprises snap close (5) and padlock (7), on described air switch box (1), be provided with snap close jack (4), insert in described snap close jack (4) one end of described snap close (5), the other end of described snap close (5) has snap close lockhole (6), on described deciliter operating grip (2), be provided with handle lockhole (3), padlock (7) is by hanging in described handle lockhole (3) and described snap close lockhole (6), described deciliter operating grip (2) being fixed with spacing.
Further, described snap close (5) is U-shaped structure, is provided with two corresponding snap close jacks (4) on described air switch box (1).
Further, described snap close (5) inserts after described snap close jack (4), and snap close (5) end position that has snap close lockhole (6) does not exceed the height of handle boss (8).
Further, described snap close (5) is insulating material.
Further, described snap close lockhole (6) is concentric holes with described handle lockhole (3).
This air switch locking device has following beneficial effect:
(1) air switch locking device of the present invention is with snap close; when when maintenance is air switch disjunction; then pull out snap close; hanging up lock can keep in repair by trouble free service; there is no key, anyone air switch that cannot close, thereby can meet production requirement; reach working service, the protection person is avoided the injury of getting an electric shock.
(2) snap close of the present invention inserts after snap close jack, and the snap close end position that has snap close lockhole does not exceed the height of handle boss, thereby when air switch closes, snap close can be shifted position inward onto, does not affect the operation of air switch, convenient and practical.

Embodiment
Below in conjunction with Fig. 3 to Fig. 6, the present invention will be further described:
An air switch locking device, comprises air switch box 1 and deciliter operating grip 2, and described deciliter operating grip 2 carries out position restriction by a locking device and air switch box 1.
As shown in Figure 3, on air switch box 1, be provided with two corresponding snap close jacks 4.
As shown in Figure 4, snap close 5 inserts after snap close jack 4, and snap close 5 end positions that have snap close lockhole 6 do not exceed the height of handle boss 8.Thereby when air switch closes, snap close can be shifted position inward onto, does not affect the operation of air switch, convenient and practical.
As shown in Figure 5, snap close 5 is U-shaped structure, at snap close 5 end positions, has snap close lockhole 6.Snap close 5 is insulating material.
As shown in Figure 6, locking device mainly comprises snap close 5 and padlock 7, on air switch box 1, be provided with snap close jack 4, insert in snap close jack 4 one end of snap close 5, the other end of snap close 5 has snap close lockhole 6, on deciliter operating grip 2, be provided with handle lockhole 3, padlock 7 is fixed deciliter operating grip 2 with spacing by hanging in handle lockhole 3 and snap close lockhole 6.
The operation principle of this air switch locking device is as follows:
Air switch divides has no progeny, when snap close 5 is pulled out, when the snap close lockhole 6 on snap close 5 is gone up with 3 pairs of handle lockholes on deciliter operating grip 2, padlock 7 is locked, and padlock 7 one loads are locked, and air switch just cannot close, only have key just can open, after padlock 7 takes off, air switch just can close, and guarantees the safety of electrical repair work.
Operating state (when air switch closes) at ordinary times, its snap close 5 can be shifted position inward onto, does not affect the operation of air switch (minute, close), convenient and practical.
By reference to the accompanying drawings the present invention has been carried out to exemplary description above; obvious realization of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present invention and technical scheme to carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all in protection scope of the present invention.
