Abstract
The invention discloses a diffusion plate protective cover, which comprises a plate frame, movable shutters, a rotating shaft, a connecting shaft and a sealing sleeve, wherein the movable shutters are arranged inside the plate frame, the movable shutters are arranged inside the plate from through the rotating shaft, the rotating shaft is connected with the connecting shaft, and the sealing sleeve is arranged on the edge of the movable shutters. By adopting the structure, the diffusion plate protective cover is simple in structure, has a shutter structure, and is convenient in adjustment and protection.
Description
Technical field
The present invention relates to diffusion sheet field, particularly relate to a kind of diffuser plate protection lid.
Background technology
Diffusion sheet is one of backlight module composition, and also someone is its diffusion sheet to diffuser plate, and major function provides a uniform area source for display. Base material need to select the material such as PET/PC/PMMA that light transmission rate is high. Generally traditional diffusion barrier is mainly in diffusion barrier base material, add the chemical particle of many, as scattering particles, and its fine particles of existing diffuser plate refers between layer in tree, so light is can traverse in the medium that constantly two refractive indexs are different again through diffusion layer, will there is the phenomenon of many refractions, reflection and scattering in light at the same time, so just causes the effect of optics diffusion. Conventional diffusion sheet colour temperature is forbidden, and display effect is poor.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of diffuser plate protection lid, simple in construction, has closing structure, conveniently regulates protection.
For solving above-mentioned technical problem; the technical scheme that the present invention adopts is: provide a kind of diffuser plate protection lid; including: sheet frame, movable shutters, rotation axle, connection axle and sealing shroud; the inside of described sheet frame is provided with movable shutters; described movable shutters is located in the inside of sheet frame by rotating; described rotation axle is connected with being connected axle, and the edge of described movable shutters is provided with sealing shroud.
In a preferred embodiment of the present invention, the anglec of rotation of described movable shutters is 360 degree.
In a preferred embodiment of the present invention, the material of described frame is rustless steel.
The invention has the beneficial effects as follows: diffuser plate of the present invention protection lid, simple in construction, there is closing structure, conveniently regulate protection.

Fig. 1 is the structural representation of diffuser plate protection lid one preferred embodiment of the present invention;
In accompanying drawing, the labelling of each parts is as follows: 1, sheet frame, and 2, rotate axle, 3, connect axle, 4, movable shutters, 5, sealing shroud.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The embodiment of the present invention includes:
A kind of diffuser plate protection lid; including: sheet frame 1, movable shutters 4, rotation axle 2, connection axle 3 and sealing shroud 5; the inside of described sheet frame 1 is provided with movable shutters 4; described movable shutters 4 is located at the inside of sheet frame 1 by rotating axle 2; described rotation axle 2 is connected with being connected axle 3, and the edge of described movable shutters 4 is provided with sealing shroud 5.
It addition, the anglec of rotation of described movable shutters 4 is 360 degree.
It addition, the material of described frame 1 is rustless steel.
Diffuser plate of the present invention protection lid provides the benefit that:
Simple in construction, has closing structure, conveniently regulates protection.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, all in like manner include in the scope of patent protection of the present invention.
