Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Can be seen that the present embodiment from Fig. 1 and Fig. 6 mainly includes filter shell 1, O-ring 2, filter piece 3, eyeglass trim rings
4 and anti-rope 5 of giving up.The anti-through hole 12 that rope 5 passes through of giving up can be made by having on filter shell, be two through holes in the embodiment,
Anti- rope 5 of giving up is set on filter shell through the through hole 12；Non-slip texture 13 is additionally provided with the outer wall of filter shell 1；Above-mentioned O
Type circle 2, filter piece 3, eyeglass trim rings 4 are respectively positioned on inside filter shell 1, and eyeglass trim rings 4 are used to compress filter piece 3.
With reference to Fig. 5, the inwall of filter shell 1 is circumferentially with annular boss 14, and the inner face of annular boss 14 circumferentially offers
Annular groove 11, O-ring 2 are located in the annular groove 11, and the thickness of O-ring is more than the depth of annular groove 11, filter piece 3
Inside filter shell 1, the sub-fraction that O-ring 2 leaks outside contacts with filter piece 3, and being extruded with by eyeglass trim rings 4
Certain decrement, it is ensured that will not be loosened because of vibrations.The diameter of filter piece 3 is slightly smaller than the internal diameter of filter shell 1, it is ensured that filter
Eyeglass 3 will not collide because of vibrations and the inwall of filter shell 1；The end face of eyeglass trim rings 4 contacts with filter piece 3, compresses filter piece 3,
Eyeglass trim rings 4 can be that class is stepped or stepped annular pressing ring, its high-order plane 41 pass through screw thread or interference with filter shell 1
Mode coordinates, and has gap between low order plane 42 and the inwall of filter shell 1, forms a space, and the space communicates with through hole, prevents
Rope of giving up can be positioned between low order plane 42 and the inwall of filter shell 1 through circular hole 12 reserved on filter shell 1, its knot
Space in, do not influence camera lens installation and light project；From this figure it can be seen that the internal diameter and eyeglass trim rings of annular boss 14
Internal diameter it is equal, do not influence light injection.
The present embodiment flashlight filter head is installed in the following manner, referring to Fig. 2 to Fig. 4：
O-ring 2 is loaded in the annular groove 11 of the inner side of filter shell 1 first；Then filter piece 3 is put into outside filter
It is in contact in shell 1 with O-ring 2；The mode that eyeglass trim rings 4 are connected through a screw thread or are interference fitted and filter shell 1 are coordinated again
And compress filter piece 4 so that O-ring somewhat deformation；Finally anti-one end for giving up rope 5 is connected through through hole 12 with filter shell 1
Connect, anti-5 knots of rope of giving up is partially in the space that the inwall of filter shell 1 cooperatively forms with eyeglass trim rings 4.
