Abstract

Disclosed is a portable lens cap, comprising a lens cap body and a chuck assembly arranged upon the inner surface of the lens cap body, wherein the chuck assembly comprises a first clamping plate, a second clamping plate, and a spring. The first clamping plate and the second clamping plate are jointed together via a pivot. The two free ends of the spring, located at the same side of the pivot, are clamped between the first clamping plate and the second clamping plate. As an elastic chuck is arranged inside the lens cap, the lens cap can be clamped upon the clothes or a knapsack of the user when the lens is used, thereby being capable of preventing the lens cap from being lost and being convenient for taking the lens cap off the clothes or knapsack to cover the lens.

Description

The Portable mirror skull

Technical field

The utility model relates to a kind of accessory of photographic goods, is specifically related to a kind of portable lens cap.

Background technology

Optical lens is the accessory commonly used of some high-end cameras and video camera, and it is installed on camera or the video camera, can make camera possess good imaging effect.

Generally; For the optical element of protecting optical lens does not receive the influence of dust and other impurities, under non-working condition, need adorn a lens cap at the front end end cover of optical lens; Lens cap is connected with the optical lens front end through the mode that clamps, can for convenience detach and spiral-lock; In use, lens cap disassembles from the front end of optical lens, because the lens cap volume is less, and can not be convenient for carrying, many times, in the process of user's photography, since too absorbed, can be easy to lens cap is lost.

The utility model content

To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of Portable mirror skull, and with optical lens in opened condition the time, it can be clipped on user's the clothes, knapsack easily, prevents loss.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

The Portable mirror skull; Comprise lens cap body and the chuck component that is installed in lens cap body inner surface; Said chuck component comprises first clamping plate, second clamping plate and a spring; Said first clamping plate are in the same place through a pivot cross-under with second clamping plate, and two free ends of said spring are in the same side of pivot and be installed between said first clamping plate and second clamping plate.

Said spring housing is contained on the pivot, and an extension is extended to the same side of pivot respectively in its two ends.

The free end of said first clamping plate and the second clamping plate facing surfaces are provided with first flange, and said second clamping plate are provided with second flange with said first flange coupling.

Said first clamping plate are provided with a rotating shaft, and said rotating shaft is actively plugged in the inner surface of said lens cap body.

Said lens cap body medial surface moulding one groove, the edge inwall of said groove is a slope.

The beneficial effect of the utility model is:

Because a collet is set in lens cap; Camera lens just can be clipped in lens cap on user's the clothes or knapsack under operating position, both can prevent that lens cap from losing; Can, camera lens fast lens cap be taken off and be buckled in the camera lens front end after being used to complete again.

Description of drawings

Fig. 1 is the structural scheme of mechanism of a kind of Portable mirror skull of the utility model;

Fig. 2 is the scheme of installation of chuck component among Fig. 1;

Fig. 3 is the user mode synoptic diagram of Portable mirror skull shown in Figure 1.

Embodiment

Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing:

Like Fig. 1, shown in 2, be a kind of Portable mirror skull of the utility model, it comprises lens cap body 1, chuck component 2, and the inboard of lens cap body 1 is a groove, and the edge inwall of groove is a slope 11.Chuck component 2 is installed in the bottom surface of groove, and it comprises clamping plate 21, clamping plate 22, pivot 23 and spring 24; Pivot 23 cross-under are at an end of

clamping plate

21,22, and the two connects into the structure that can rotate mutually with it, and spring 24 is socketed in the outside of pivot 23; Its two ends are outward extended with an extension 241 respectively; These two extensions 241 are positioned at the same side of pivot, and its two end is close to the medial surface of the outer end of clamping plate 21 and clamping plate 22 respectively, and two extensions 241 are under the elastic reaction of spring; Respectively clamping plate 21 and clamping plate 22 are exerted pressure, make clamping plate 21 and clamping plate 22 remain the trend of fastening.

An end relative with pivot on clamping plate 21 and the clamping plate 22 (be its two rotation free end) is respectively arranged with flange 211 and flange 221, and its flange 211 is positioned on clamping plate 21 and clamping plate 22 facing surfaces, and flange 221 is corresponding with flange 211.In conjunction with Fig. 3, clamping is carried out to clothes in the gap between flange 211 and the flange 221, and under the elastic reaction of spring 24, the pretightning force of the clothes clamping that remains.

For another example Fig. 1, shown in 2,, also be provided with a rotating shaft 212 in the bottom of clamping plate 21, this rotating shaft 212 is inserted into lens cap body 1 inner surface, thereby makes that whole chuck component 2 can be along A to rotating with respect to lens cap body 1.

Certainly, in order to guarantee the normal use of lens cap, guarantee it when fastening with camera lens, chuck component 2 can not collide the inner optical element of camera lens, should lens cap body 1 inboard depth of groove be made into suitable dimensions.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
