Abstract
The utility model belongs to the field of electric appliances and provides a distribution box with an explosion-proof warning function. The distribution box comprises a distribution box body and is characterized in that a support is provided above the distribution box body; a stroke switch is arranged on the support and is connected with an alarm; and the support above the distribution box body is provided with a push rod and an articulated lever, the push rod can slide up and down, the upper end of the push rod is abutted against a first end of the lever, the lower end of the push rod is abutted against a movable part of the stroke switch, and a distance from an articulated part of the lever to the first end is smaller than a distance from the articulated part of the lever to another end. When an abnormal event occurs in the distribution box body, more gas is generated to trigger the alarm, and the alarm sends an alarm to remind people of maintenance, and thus the distribution box is advantaged by preventing an accident.
Description
Technical field
The utility model belongs to appliance field, specifically relates to distribution box.
Background technology
Distribution box has casing, electrical equipment is installed in casing when use, in the time that box house breaks down, in casing, can produce in a large number gas, air pressure inside raises fast, in prior art, casing outside does not have other alarming device, and the gas that causes pressure the to raise phenomenon of usually blasting, when casing explosion time, can damage other electrical equipment in casing, cause damage.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides that a kind of gas that breaks down, produces when box house is more, pressure can remind people to overhaul when larger, and the distribution box with explosion-proof warning of other electrical equipment occurs, protects minimizing accident.
The technical scheme that the utility model adopts is: have the distribution box of explosion-proof warning, comprise distribution box body, it is characterized in that: above described distribution box body, have support, travel switch is installed above support, travel switch is connected with alarm.
Say further, can slide up and down push rod and hinged lever are set on the support above described casing, push rod upper end heads on the first end of lever, the lower end of push rod heads on above casing, the other end of lever heads on the moving part of travel switch, and the hinged place of lever is less than the distance of hinged place to the other end to the distance of first end.
The beneficial effects of the utility model are: when occurring when abnormal, will to produce more gas in casing, give the alarm, remind people's maintenance, have advantages of the generation of preventing accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. distribution box body 2. support 3. travel switch 4. alarms 5, push rod 6, lever.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, there is the distribution box of explosion-proof warning, comprise distribution box body 1, it is characterized in that: described distribution box body 1 has support 2 above, support 2 is provided with travel switch 3 above, travel switch is connecting alarm 4, and in the time that casing internal gas pressure raises, casing will be out of shape like this, the casing of distortion acts on travel switch, travel switch is connecting alarm, and alarm will be reported to the police, and plays effect of the present utility model.
Say further, can slide up and down push rod 5 and hinged lever 6 are set on the support above described casing, push rod upper end heads on the first end of lever, the lower end of push rod heads on above casing, the other end of lever heads on the moving part of travel switch, and the hinged place of lever is less than the distance of hinged place to the other end to the distance of first end; In the time breaking down in casing, in casing, will produce more gas, when casing internal gas pressure raises, casing will be out of shape, and the casing of distortion acts on push rod, and a less displacement is moved in push rod one end, the other end will move larger displacement, acts on travel switch, and reaction is sensitiveer like this.
Claims (2)
