Description
Technical field
This utility model relates to apparatus for making a video recording, particularly relates to the packing ring of pick-up lens.
Background technology
At present, apparatus for making a video recording is carried with.When carrying, camera lens generally covers with lens cap, it is prevented that the situations such as camera lens scratches, water inlet occur.But, there is certain interval between lens cap and camera lens, barrier propterty is good not.It is therefore desirable to increase gasket construction reasonable in design between lens cap and camera lens, it is provided that higher sealing effectiveness.
Summary of the invention
The purpose of this utility model is in that to provide a kind of gasket construction for pick-up lens, has sealing property well, can effectively protect pick-up lens.
The technical scheme realizing above-mentioned purpose is:
A kind of gasket construction for pick-up lens, is installed on lens cap, and described gasket construction includes annular base plate, ring-shaped rubber pad, the first sealing ring and the second sealing ring, wherein
Described lens cap is fixed in the outside of described annular base plate, and inner side has first annular groove；
Described ring-shaped rubber pad is fixed in described first annular groove, and has the second cannelure inside this ring-shaped rubber pad；
Two sides in described second cannelure have the first ring groove holding described first sealing ring respectively and the second ring groove holding described second sealing ring.
In the above-mentioned gasket construction for pick-up lens, described lens cap is provided with the boss of annular；The outside of described annular base plate has and holds the mounting groove that described boss embeds.
In the above-mentioned gasket construction for pick-up lens, described annular base plate and the respective cross section of described ring-shaped rubber pad are all U-shaped.
The beneficial effects of the utility model are: this utility model is by designing ring-shaped rubber pad and sealing ring, it is provided that sealing and shock resistance well, increases by a pipe protection structure, effectively protect pick-up lens between lens cap and camera lens.
Accompanying drawing explanation
Fig. 1 is the structure chart of pick-up lens；
Fig. 2 is the gasket construction of the present utility model sectional view when being installed on lens cap.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, the gasket construction for pick-up lens 100 of the present utility model, be installed on lens cap 200.Gasket construction includes annular base plate 1, ring-shaped rubber pad the 2, first sealing ring 3 and the second sealing ring 4.
Lens cap 200 is fixed in the outside of annular base plate 1, and inner side has first annular groove, and cross section is U-shaped.Ring-shaped rubber pad 2 is fixed in first annular groove, and has the second cannelure inside this ring-shaped rubber pad 2, and cross section is U-shaped.
Two sides in second cannelure have the first ring groove holding the first sealing ring 3 respectively and hold the second ring groove of the second sealing ring 4, and the first ring groove and the second ring groove are relative up and down.First sealing ring 3 protrudes from the first ring groove, and the second sealing ring 4 protrudes from the second ring groove.
Lens cap 200 is provided with the boss 201 of annular.The outside of annular base plate 1 has and holds the mounting groove that boss 201 embeds.
Above example is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when without departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
