And the setting of groove, then the visual field of the second peep hole as seen from the outside inward is expanded, therefore the first peep hole and the second peep hole can
Smaller with what is done, further attenuating glass is scraped or damaged possibility.
Further, the edge circumferential array of first peep hole has block.
By using above-mentioned technical proposal, the setting of block can stop to the object that may damage glass.
Further, first peep hole and the second peep hole have two respectively.
By using above-mentioned technical proposal, two the first peep holes facilitate people's eyes to be observed.
Further, the inner wall edge circumferential array of the observation lid has the first screwed hole for installing glass.
By using above-mentioned technical proposal, glass is circumferentially fixed in observation lid inwall by the first screwed hole.
Further, the inwall of the observation lid is provided with the second screwed hole between described two second peep holes.
By using above-mentioned technical proposal, the setting of the second screwed hole, glass is set to be bonded with observation lid inwall even closer,
To increase the air-tightness of glass and observation lid.
Further, the observation lid inwall is axially projecting the snap ring coordinated with the cylinder inboard wall.
By using above-mentioned technical proposal, it is bonded after snap ring insertion cylinder with cylinder inboard wall, adds observation lid and cylinder
Air-tightness.
Further, the observation lid inwall is provided with sealing ring around the snap ring is axially projecting, the cylinder with it is described
The observation panel of observation lid is provided with the seal groove coordinated with the sealing ring.
By using above-mentioned technical proposal, sealing ring is with after seal groove clamping, further enhancing observation lid and cylinder
Air-tightness.
Further, the cylinder and observation cover outer wall are covered with electrolytic coating.
By using above-mentioned technical proposal, the setting of electrolytic coating, the corrosion resistance of whole housing can be improved.
In summary, the utility model has the advantages that：Cavity is formed between projection and observation lid, covers observation
The glass of interior installation and the first peep hole form a segment distance, so as to subtract reduce glass scratched by the object outside the first peep hole or
Damaged possibility；And the setting of groove, then expand the visual field of the second peep hole as seen from the outside inward, thus the first peep hole and
Second peep hole can be done smaller, and further attenuating glass is scraped or damaged possibility.
