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, bayonet lock latch mechanism comprises a bayonet lock 5 and two the second screws 7.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.
A bayonet lock 5 is fixed on the rear of optical instrument cone 8 end flange by two the second screws 7, 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 bayonet lock latch mechanism, and the bayonet lock 5 skewed slot opening 9-1 corresponding with it in each bayonet lock latch mechanism is slidably connected.Skewed slot opening 9-1 is according to screwing clockwise, the direction setting of outwarding winding counterclockwise.
The two ends that mirror covers 9 outer faces are respectively equipped with 6 screw unthreaded holes, and two handles 11 are fixed on by 6 the first screw 4 symmetries the external diameter edge that mirror covers 9 outer faces respectively.
As shown in Figures 5 to 9, one end of ratchet bayonet lock 10 is that end is externally threaded round bar 10-1, and the stage casing of ratchet bayonet lock 10 is square boss 10-2, and the other end of ratchet bayonet lock 10 is provided with ratchet wheel hook 10-3.Ratchet button 13 is provided with internal thread 13-1, the base of handle 11 is provided with ratchet bayonet lock mounting hole, this ratchet bayonet lock mounting hole comprises square hole 11-1, the first circular hole 11-2 and the second circular hole 11-3, the round bar 10-1 of ratchet bayonet lock 10 is through the first circular hole 11-2, square boss 10-2 is through the square hole 11-1 on handle 11 bases and be slidably connected with it, and the round bar 10-1 that spring 12 is enclosed within ratchet bayonet lock 10 goes up and be positioned at the second circular hole 11-3 of handle 11.
The external thread of the internal thread 13-1 of ratchet button 13 and round bar 10-1 termination is connected.Each ratchet latch mechanism is taken turns hook 10-3 by ratchet and is meshed with ratchet gear teeth 8-1 corresponding on optical instrument cone 8.
