Type, flanged plate is coaxially disposed with cylinder；The camera body is fixed on the cylinder inner wall；
The flanged plate and the extension are coaxial docking fixation, to cause glass marble cover to cover camera body completely
Firmly, and the shooting end of camera body is stretched within glass ball cover, flame proof sealing is accompanied between the flanged plate and extension
Pad；The inwall 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 passed from the plug screw for being 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 is 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 is compressed, 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
It is 7 buttons to screw up button number.
Further, the cable is circumferentially coated with fluid sealant, and the sealing in the end for passing flame proof sealing ring
Glue is full of in the space between pressing plate through hole and cable.
Further, gasket seal is provided between pressing plate and the flame proof sealing ring.
Beneficial effects of the present invention：The present invention hemispheric cloche, the glass in camera body outer cup
Cover sets flame-proof sealing gasket to realize two with an extension for being connected with flanged plate between extension and flanged plate
The sealing of person junction, compresses sealing gasket, connection glass ball cover and interior mounting cylinder, it is to avoid in glass using the bolt connection of flanged plate
It is threaded on glass, reduces cloche intensity, more eliminate and be threaded to realize the unreliability being tightly connected on glass；Together
When, then coupled by the flame proof thread set between inside and outside mounting cylinder, between plug screw and outer mounting cylinder, then it is aided with the flame proof of compression
Packing ring threading, is tightly connected to realize to whole device, it is to avoid dust, combustibles are contacted into inside with electrical connector, from
And preferably realize that flame proof is acted on, its simple and compact for structure, highly reliable, flame proof works well.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
