Description
Technical field
The utility model is related to a kind of electrical equipment, and in particular to a kind of explosion-proof lamp set.
Background technology
The hazardous areas such as colliery, combustion gas widely use explosion-proof lamp set, existing explosion-proof lamp set include lamp block set, pressure cap, sheath,
Lampshade, pressure cap is sleeved on lamp block set end, and is threadedly coupled, and sheath is arranged in pressure cap inner chamber, and sheath openend is provided with turns up
Be clipped in the middle for the sheath openend flange that turns up by flange, the lampshade hole end surface that turns up in the end face of flange lamp block set relative with its.Lamp
Cover, sheath play protective action, but the sealing covered between sheath and lamp block set due to existing explosion-proof lamp is bad, therefore, protection is not
It is reliable.
The content of the invention
In view of the shortcomings of the prior art, proposing that one kind can significantly improve between sheath and lamp block set sealing can for the utility model
By property, so as to significantly improve the Novel explosion-proof lamp set of protection reliability.
The utility model is achieved through the following technical solutions technical goal.
Novel explosion-proof lamp set, including lamp block set, pressure cap, sheath, lampshade；The pressure cap is sleeved on lamp block set end, and spiral shell
Line is connected；The lampshade is the hood-like component of opening, and its openend is arranged in pressure cap hole, and openend outer wall is provided with the shaft shoulder, axle
In shoulder wedge pressure cap aperture annular groove；Sheath is provided with the inner chamber of the pressure cap；The sheath is the hood-like component of opening, its openend
It is provided with the flange that turns up, the lampshade hole end surface that turns up in the end face of flange lamp block set relative with its exists the sheath openend banjo clip that turns up
It is middle；It is theed improvement is that：Annular groove I, ring are provided with the lampshade hole end surface in the relative lamp block set of end face of flange that turns up
It is provided with the first O-ring seals in groove I, the first O-ring seals and lampshade turn up end face of flange tight fit, form axial seal knot
Structure.
In said structure, the lampshade flange that turns up is stretched into lamp block set in hole end surface annular groove I, and the lampshade flange that turns up is provided with
The second O-ring seals are provided with annular groove II, annular groove II, the second O-ring seals are closely matched somebody with somebody with the inwall of hole end surface annular groove I in lamp block set
Close, form radial seal structure.
The utility model compared with prior art, has the positive effect that：
1st, lampshade to turn up and be provided with axial seal structure between hole end surface in end face of flange, lamp block set corresponding thereto, significantly
Sealing reliability between sheath and lamp block set is improved, so as to significantly improve the utility model protection reliability.
2nd, lampshade to turn up and be provided with radial seal structure between hole end surface annular groove I in flange and lamp block set, further improves shield
Sealing reliability between set and lamp block set, so as to further improve the utility model protection reliability.
