Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As shown in Figure 3 and Figure 4, the anti-tripping camera lens packoff of the present invention comprises: O-ring seal 6, optical instrument cone 8, mirror lid 9, two handles 11, at least three bayonet lock latch mechanisms and two ratchet latch mechanisms, wherein, the bayonet lock latch mechanism comprises a bayonet lock 5 and two the second screws 7.The ratchet latch mechanism comprises a plurality of the first screws 4, ratchet bayonet lock 10, spring 12 and ratchet button 13.
The end flange external diameter part of optical instrument cone 8 is provided with ratchet gear teeth 8-1, and O-ring seal 6 is bonding by the front end face of D04 glue and optical instrument cone 8 flanges.
Bayonet lock 5 is fixed on the rear of optical instrument cone 8 end flange by two the second screws 7, and at least three bayonet lock latch mechanisms distribute along the end flange even circumferential of optical instrument cone 8.The sidewall of mirror lid 9 is provided with at least three skewed slot opening 9-1, and skewed slot opening 9-1 is corresponding one by one with the bayonet lock latch mechanism, and the skewed slot opening 9-1 that the bayonet lock 5 in each bayonet lock latch mechanism is corresponding with it is slidingly connected.Skewed slot opening 9-1 is according to screwing clockwise, the direction setting of outwarding winding counterclockwise.
