Abstract
A device for quickly assembling and disassembling a waterproof lens cover comprises a cover, a handle, a sealing ring and a lens hood. The cover is provided with three flanges which are 120 degrees mutually, the angle of the flanges is alpha, one end of each flange is a linear surface, and the other end of each flange is a spiral surface; correspondingly, the light shield is also provided with three flanges which are linear surfaces and are 120 degrees with each other, and one end of each flange is provided with a spiral surface which has the same pitch and the same spiral direction as the cover. The cap is screwed into the light shield through the spiral surface, and axial force is generated in the screwing process to enable the linear surface and the spiral surface of the cap to be combined with the linear surface and the spiral surface of the light shield respectively to form extrusion, so that the connection between the cap and the light shield is completed. Similarly, the cover is screwed out of the light shield in the opposite direction through the spiral surface, and the cover and the light shield are disassembled. The arrangement is such that the cap is both inserted and removed, i.e. screwed in and out, at angles of less than 120. The lens cap can be assembled and disassembled quickly; meanwhile, an O-shaped sealing ring is arranged in the device, so that the device has a waterproof function.
Description
Technical field

Technical solution of the present invention: a kind of loading, unloading Water-resistant mirror cranial device fast, comprising: lid, handle, O-ring seal, light shield; Lid is connected by screw with handle.Lid is provided with 120 ° of three place's flange each other, and the angle of flange is α, and light shield is also correspondingly provided with 120 ° of three place's flange each other, and the angle of flange is β, β >=α, 60 ° of α, β <.Flange and flange are provided with identical helicoid, lid screws in light shield by the flange on it and the flange on light shield with helicoid dextrorotation, in process, produce axial force screwing, the planarea of flange is engaged with the B face on light shield, continue rotation, flange forms extruding with planarea and helicoid to the helicoid of B face and flange again.Complete lid and being connected of light shield.In like manner, lid by the flange on it and the flange on light shield with the left-handed back-out light shield of helicoid.Between lid and light shield, be provided with the first O-ring seals.
At the quick loading, unloading Water-resistant mirror of described one cranial device, between screw and lid, be provided with the second O-ring seals.
At the quick loading, unloading Water-resistant mirror of described one cranial device, the threaded hole that handle (3) is connected with screw (6) is blind hole.
At the quick loading, unloading Water-resistant mirror of described one cranial device, handle (3) is provided with arc surface (11).
The present invention compared to existing technology tool has the following advantages:
(1) loading, unloading lens cap easily fast.The present invention is owing to being provided with 120 ° of three place's flange each other to lid, and light shield is also correspondingly provided with 120 ° of three place's flange each other, and flange and flange are provided with identical helicoid, and 60 ° of α, β <.When lid packs light shield into helicoid, be less than in 120 ° of situations in rotation, three place's flanges will form extruding with planarea and helicoid to the helicoid of B face and three place's flanges, complete packing into of Jing Gai.In like manner, by helicoid, be less than in 120 ° of situations in reverse rotation, lid screws out light shield.
(2) axially and be radially seamless connectivity.Lid and the catenation principle of light shield be plane to the mutual extruding producing between B face and two helicoids, owing to having adopted a pair of helicoid, be squeezed in axially and radially both direction all produced component, make to cover and realized seamless connectivity with being connected of light shield.
(3) waterproof.In the present invention, between lid and light shield, be provided with an O shape sealing.Between screw and lid, be provided with the second O-ring seals.The threaded hole that handle is connected with screw is blind hole.
