Abstract
The invention discloses a large spliced screen based on laser projection. The large spliced screen comprises a screen frame and screen modules, wherein the screen modules are crossed to be fixed in the screen frame, a bulging shaft is arranged on two parallel surfaces of each screen module, and No.1 counter bores capable of accommodating the bulging shaft are formed in the other group of parallel surfaces; a group of No.2 counter bores are evenly formed in edges of inner sides of the screen frame and can also accommodate the bulging shaft. Compared with the prior art, the screen modules are fixed through matching of shaft holes, besides, the defects that #-shaped frames are large in size, heavy and not easy to move are overcome, and meanwhile, the outer frame has the basically stabilizing function.
Description
Technical field
The invention belongs to electronic applications, be specifically related to a kind of splicing large screen based on laser projection.
Background technology
The little liquid crystal display of liquid crystal-spliced screen polylith is spliced.The neglecting demand greatly and determine of liquid crystal-spliced screen, general number is between 2 ~ 16 pieces.Traditional liquid crystal-spliced screen needs to rely on framework to form groined type, then is interted fixedly to enter by each little liquid crystal display.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provides a kind of splicing large screen based on laser projection.
Technical scheme: in order to reach foregoing invention object, the present invention has specifically come like this: a kind of splicing large screen based on laser projection, comprise screen frame and screen module, described screen module is mutually interspersed to be fixed in screen frame, two faces that described screen module parallels are provided with prominent axle, and another is organized two parallel faces and is provided with a counterbore that can hold prominent axle; Described screen frame inside edge is evenly provided with one group of No. two counterbore, and No. two counterbores also can hold prominent axle.
Wherein, the spacing of adjacent No. two counterbores on described screen frame be 2 screen module the length of side and.
Beneficial effect: the present invention, compared with conventional art, reaches the object of fixed mask module by shaft hole matching, and the shortcoming avoiding large, the heavy not easily movement of volume that groined type framework brings, but external frame has and can substantially reach firm effect simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that module of the present invention is dashed forward axle place schematic diagram;
Fig. 3 is module counterbore place of the present invention schematic diagram;
Fig. 4 is screen frame inside edge of the present invention schematic diagram.
Embodiment
A kind of splicing large screen based on laser projection as shown in Figure 1, comprise screen frame 1 and screen module 2, described screen module 2 is mutually interspersed to be fixed in screen frame 1, two faces that described screen module 2 parallels are provided with prominent axle 3, and another is organized two parallel faces and is provided with a counterbore 4 that can hold prominent axle; Described screen frame 1 inside edge is evenly provided with one group of No. two counterbore, 5, No. two counterbores 5 also can hold prominent axle 3, the spacing of adjacent No. two counterbores 5 on described screen frame 1 be 2 screen module 2 the length of side and.
