Backplate and second protection board, are fixedly installed the first bar magnet on one, and another rotation connection is provided with and described the
Corresponding second bar magnet of one bar magnet.
Projector lens protective device described in the utility model, wherein finite place piece is fixedly installed on the track strip,
The locating part is located at centre position right over the camera lens.
Projector lens protective device described in the utility model, wherein the locating part is limited block；Described first protects
It is both provided with notch corresponding with the limited block on backplate and second protection board.
Projector lens protective device described in the utility model, wherein further include two respectively with first bar shaped
Magnet and second bar magnet correspond to the limit iron bar of absorption；Two limit iron bars are located at described camera lens or so
Both sides.
The beneficial effects of the utility model are：When not in use, sliding two protection boards makes it draw close, by two bar shapeds
The magnetic force of magnet is adsorbed, and is protected to camera lens, in use, the second bar magnet is rotated 180 degree, utilizes two magnet
Repulsion make the separation of two protection boards, then open manually, simple in structure, easy to use, protecting effect is good.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below in conjunction with attached drawing and reality
Applying example, the utility model is described in further detail, and the accompanying drawings in the following description is only the section Example of the present invention, for this
