Background technology
At present, main flow mobile phone is all furnished with post-positioned pick-up head, is convenient to that user takes pictures and recorded video.But a lot of people can fall mobile phone on the ground because of carelessness; or extruding mobile phone; because camera pilot hole place on cell phone rear cover is subject under the concentrated impact of stress; phone cover deformation comparison is large; add the cell phone rear cover part of conventionally closing on camera pilot hole place and be all conventionally slightly projection, this will make post-positioned pick-up head be greatly affected, as impaired in screening glass surface; can cause image fog to follow-up shooting use, even cause camera to damage.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide the cell phone rear cover that protection can be provided mobile phone post-positioned pick-up head.
The technical solution of the utility model is achieved in that the cell phone rear cover with post-positioned pick-up head safeguard structure, comprises the safeguard structure of cell phone rear cover main body and post-positioned pick-up head, in described cell phone rear cover main body, offer installing hole, described safeguard structure comprises protective sleeve, mounting cylinder, buffer gasket and diaphragm, one end of described protective sleeve is fixedly connected with one end of described mounting cylinder, on the sidewall outer surface of described mounting cylinder around axially offering fitting recess, the internal diameter of described mounting cylinder is less than the aperture of described installing hole and the internal diameter of described protective sleeve, and the external diameter of described mounting cylinder is more than or equal to the internal diameter of described protective sleeve, described buffer gasket and described diaphragm are all arranged in described protective sleeve, and described diaphragm is located at described buffer gasket and described mounting cylinder closes between the end face of described protective sleeve, the housing clamping that described safeguard structure closes on described installing hole by described fitting recess and described cell phone rear cover main body is assemblied in described cell phone rear cover main body, and described protective sleeve is positioned at the inner side of described cell phone rear cover main body.
The above-mentioned cell phone rear cover with post-positioned pick-up head safeguard structure, the internal diameter of described buffer gasket is more than or equal to the external diameter of post-positioned pick-up head lens barrel, and the external diameter of described buffer gasket is less than or equal to the internal diameter of described protective sleeve and is greater than the internal diameter of described mounting cylinder.
The above-mentioned phone cover with post-positioned pick-up head safeguard structure, described protective sleeve, described buffer gasket and described mounting cylinder all adopt elastomeric material to make, and described diaphragm adopts wear-resisting transparent material to make.
The beneficial effects of the utility model are: the utility model is damaged can avoid mobile phone post-positioned pick-up head collided with or push in the camera position of cell phone rear cover time; and wear-resistant protection film can prevent that lens protection sheet from being ground flower; in addition the utility model is simple in structure, and part replacement is convenient.
