Abstract
A movable explosion-proof switch relates to the technical field of switches, and comprises a columnar sealed container, wherein the upper and the lower ends of the columnar sealed container are provided with through holes, rubber pads which are matched with the through holes are installed in the through holes, metallic contacts are arranged in the rubber pads, electricity conducting liquid is contained in the columnar sealed container, the outer wall of the columnar sealed container is provided with a liquid injecting hole, a sealing cover is arranged on the liquid injecting hole, and the switch has better explosion-proof property.
Description
Technical field
The utility model relates to switch.
Background technology
Existing switch is made with copper sheet, utilize the copper sheet conduction, the time that this switch is used has been grown, will produce friction between the copper sheet, so, be to produce electric spark at make-and-break contact easily just, be used in factory etc. and contain the place of explosion hazard gases and just blast easily that explosion-proof performance is bad.
The utility model content
In order to overcome the bad deficiency of existing copper sheet switch explosion-proof performance, the utility model provides a kind of movable flame-proof switch, and this movable flame-proof switch has explosion-proof performance preferably, and can inject at any time and pour out liquid, and is easy to use.
The utility model adopts following technical scheme, a kind of movable flame-proof switch, comprise cylindrical closed vessel, the two ends up and down of cylindrical closed vessel have through hole, the rubber blanket that is complementary is installed in the through hole, is provided with hard contact in the rubber blanket, fill conducting liquid in the cylindrical closed vessel, the outer wall of cylindrical closed vessel has liquid injection hole, and liquid injection hole is provided with seal cover.
The beneficial effects of the utility model are, because this movable flame-proof switch, comprise cylindrical closed vessel, the two ends up and down of cylindrical closed vessel have through hole, the rubber blanket that is complementary is installed in the through hole, be provided with hard contact in the rubber blanket, fill conducting liquid in the cylindrical closed vessel, the outer wall of cylindrical closed vessel has liquid injection hole, liquid injection hole is provided with seal cover, and therefore, this movable flame-proof switch has explosion-proof performance preferably, and can inject at any time and pour out liquid, easy to use.
Description of drawings
Fig. 1 is the structural representation of the movable flame-proof switch of the utility model;
Embodiment
As shown in Figure 1, a kind of movable flame-proof switch, comprise cylindrical closed vessel 1, the two ends up and down of cylindrical closed vessel 1 have through hole, the rubber blanket 2 that is complementary is installed in the through hole, is provided with hard contact 3 in the rubber blanket 2, fill conducting liquid 4 in the cylindrical closed vessel 1, the outer wall of cylindrical closed vessel 1 has liquid injection hole 5, and liquid injection hole 5 is provided with seal cover 6.This conducting liquid 4 is a mercury.
Because fill mercury in the utility model cylindrical closed vessel 1, the two ends of cylindrical closed vessel 1 have can with the contacted hard contact 3 of mercury, in vertical state the time, the hard contact 3 of upper end does not contact with mercury at cylindrical closed vessel 1, and the utility model switch is off-state.When cylindrical closed vessel 1 was the level of state, the hard contact 3 at cylindrical closed vessel 1 two ends linked together with the mercury conductor, and promptly the utility model switch is opening.The utility model can also pass through liquid injection hole 5, injects at any time and pours out mercury, and is easy to use, so the utility model is safe, has explosion-proof performance preferably.
Claims (1)
1, a kind of movable flame-proof switch, comprise cylindrical closed vessel (1), it is characterized in that: the two ends up and down of cylindrical closed vessel (1) have through hole, the rubber blanket (2) that is complementary is installed in the through hole, be provided with hard contact (3) in the rubber blanket (2), fill conducting liquid (4) in the cylindrical closed vessel (1), the outer wall of cylindrical closed vessel (1) has liquid injection hole (5), and liquid injection hole (5) is provided with seal cover (6).
