Firmly, and the shooting end of camera body is stretched within glass ball cover, and flame proof sealing is accompanied between the flanged plate and extension section
Pad；The inner wall of the outer wall of the cylinder and outer mounting cylinder, which prolongs, is equipped with flame proof thread on its length direction, the other end of cylinder is twisted
Enter in outer mounting cylinder, the cable of the camera body is pierced by from the plug screw for be again provided with flame proof thread；
The plug screw is screwed into the one end of outer mounting cylinder away from glass ball cover, and it is heavy that the hexagonal (hexagon)nut end of the plug screw is additionally provided with
Hole, the counterbore are embedded with flame proof sealing ring, and the circular pressing plate that the flame proof sealing ring is close to outer mounting cylinder end face compresses, institute
State the through hole that cable is extruded out of described flame proof sealing ring and passes through pressing plate.
Further, the precision of the flame proof thread is not less than 3 grades, and pitch is not less than 0.6mm, is threadedly engaged the minimum in face
Button number is screwed up as 7 buttons.
Further, the cable is circumferentially coated with fluid sealant, and the sealing in the endface for being pierced by flame proof sealing ring
Glue is full of in the gap between pressing plate through hole and cable.
Further, it is equipped with gasket seal between pressing plate and the flame proof sealing ring.
The beneficial effects of the utility model：The utility model hemispheric glass in camera body outer cup
Cover, the cloche have an extension section for being used to be connected with flanged plate, set flame proof to seal between extension section and flanged plate
Pad to realize the sealing of the two junction, gasket, connection glass ball cover and interior installation are connected using the bolt of flanged plate
Cylinder, avoids being threaded on glass, reduces cloche intensity, more eliminates and be threaded on glass to realize sealed connection
Unreliability；Meanwhile then the flame proof thread by being set between inside and outside mounting cylinder, between plug screw and outer mounting cylinder couple, it is then auxiliary
Threaded with the flame proof packing ring of compression, to realize the sealed connection to whole device, avoid dust, combustibles from entering internal and electric
Junction contacts, so as to preferably realize that flame proof acts on, its simple and compact for structure, highly reliable, flame proof works well.
