Description

Lens cap

Technical field

The present invention relates to a kind of lens cap.

Background technology

In order to prevent that spots such as dust are infected with on the camera lens as electronic equipments such as camera, video cameras, normally by a sheathed lens cap on camera lens.Can when electronic equipments such as camera, video camera do not use, lens cap be covered on the camera lens of electronic equipment like this, prevent that spots such as dust are infected with on the camera lens.

When needs use camera, video camera etc. to be provided with the electronic equipment of camera lens, then need lens cap is taken, camera lens is exposed, just can make light enter the inside of electronic equipment by the eyeglass on the camera lens, the user just can find a view and take or record etc.Therefore, when often exposing as if camera lens, then the outside surface of the eyeglass in the camera lens can be infected with spots such as dust.And, if use take or record finish after, forget lens cap is sheathed on the camera lens, also can cause being infected with on the camera lens dust.Yet the dust of being infected with on the eyeglass can directly influence the inside that light enters electronic equipment, thereby can influence imaging effect.

Summary of the invention

In view of this, be necessary to provide a kind of lens cap that is used for eyeglass on the clean lens.

A kind of lens cap comprises cover body and is located on the cover body hairbrush with clean lens.

When above-mentioned lens cap is covered on the camera lens, rotate, can reach the purpose of clean lens by the hairbrush that is arranged on the cover body.

Embodiment

Shown in Fig. 1,2 and 3, lens cap 100 comprises cover body 10, be arranged at hairbrush 20, the handle 30 in the cover body 10 and be fixed on handle 30 on the hairbrush 20 and make the fixture 40 that hairbrush 20 can rotate with respect to cover body 10 along with handle 30.

Cover body 10 comprises top board 11 and the continuous side walls 12 of the annular of extending from the edge of top board 11.Top board 11 is rounded, top board 11 comprise first surface 111 and with the opposing second surface 112 of first surface 111.Top board 11 centers offer a perforation 113 through top board 11, and perforation 113 is through first surface 111 and second surface 112.First surface 111 is a smooth face.Sink and form resettlement section 114 in second surface 112 middle parts.Sidewall 12 extends from the edge-perpendicular of first surface 111.

Hairbrush 20 is arranged on the first surface 111, and is contained in the cover body 10, and it is roughly elongated.Hairbrush 20 have first side 21 and with the second opposing side 22 of first side 21.First side 21 is provided with and convexes with certain position post 24 on bristle 23, the second sides 22, offers a pilot hole 241 on the reference column 24.Pilot hole 241 is a blind hole, and it is opened on the reference column 24 away from the end of second side 22, and pilot hole 241 is provided with internal thread.The size of reference column 24 is less than the size of perforation 113.In the present embodiment, hairbrush 20 is provided with separately with top board 11, and in other embodiments, hairbrush 20 can be set to and top board 11 one.

Handle 30 is the tabular body of a strip, and it can be located in the resettlement section 114.Handle 30 be provided with can be relatively fixed hole 31 and be convenient to point the through hole 32 of placement of perforation 113.Fixed orifice 31 and through hole 32 are set up in parallel on the length direction of handle 30.Fixed orifice 31 comprises the first hole portion 311 and the second hole portion 312 that communicates with the first hole portion 311, and wherein, the size of the first hole portion 311 is less than the size of the second hole portion 312 and perforation 113, and equals the size of pilot hole 241.The first hole portion 311 is provided with internal thread.Through hole 32 is an elongate in shape.

Fixture 40 is elements such as screw, rivet, its the second hole portion, 312 backs that can pass through hole 31 in turn screw togather, are screwed in the pilot hole 241 that is contained in the perforation 113 with the first hole portion 311, thereby fixedly on the hairbrush 111, make hairbrush 111 to rotate handle 30 along with handle 30.In addition, the head 41 of fixture 40 can be ccontaining with the second hole portion 312 in, make the head 41 of fixture 40 flush with handle 30.

During assembling: at first that second side 22 of hairbrush 20 is relative with the first surface 111 of top board 11, and fit on the first surface 111, reference column 24 is placed in the perforation 113, make hairbrush 20 to rotate with respect to cover body 10; Then, handle 30 is arranged in the resettlement section 114, and the first hole portion 311 of through hole 31 is relative with pilot hole 241; At last, fixture 40 is passed the second hole portion 312 back screws togather, screw togather with pilot hole 241 again, make when handle 30 rotates, can drive hairbrush 20 and rotate with the first hole portion 311, and the head 41 of fixture 40 can be ccontaining with the second hole portion 312 in.So far, assembling finishes.

As shown in Figure 4, camera lens 200 comprises lens barrel 201 and the eyeglass 202 that is arranged in the lens barrel 201.During use: at first that the first surface 111 of cover body 10 is relative with camera lens 200, and lens cap 100 is covered on the camera lens 200, at this moment, the bristle 23 of hairbrush 20 contacts with eyeglass 202; Then, finger is positioned in the through hole 32, and apply an acting force, making handle 30 drive hairbrush 20 sweeps on the relative periphery of eyeglass 202 and cover body 10, thereby hairbrush 20 can brush dust on the relative periphery of camera lens 200 and cover body 10, spot etc., reach the purpose of clean lens 200, and be convenient to user's operation.In the present embodiment, the length of hairbrush 20 equals on the eyeglass 202 diameter of the periphery relative with cover body 10, and in other embodiments, the length of hairbrush 20 can be greater than the diameter of periphery relative with cover body 10 on the eyeglass 202.

If hairbrush 20 is set to one with top board 11, then can directly rotate cover body 10, make hairbrush 20 on the relative periphery of eyeglass 202 and cover body 10, to sweep, also can reach the purpose of clean lens 200.

In addition, as shown in Figure 5, hairbrush 20a on the cover body 100a is set to circle, its size is more than or equal to the size of periphery relative with cover body 10 on the eyeglass 202, when hairbrush 20a rotates, can brush dust on camera lens 200 periphery relative, spot etc., reach the purpose of clean lens 200 with cover body 10a.
