Screen frame and laser projection display device

Abstract

The invention provides a screen frame and a laser projection display device. The screen frame comprises a plurality of side frames connected end to end, and a plurality of connecting parts are arranged at the joint of every two adjacent side frames. Containing grooves corresponding to the connecting parts in a one-to-one mode are formed in the joints of the side frames and the adjacent side frames, the connecting parts are provided with inserting parts capable of extending into the containing grooves, the inserting parts are provided with telescopic clamping parts, and containing holes corresponding to the clamping parts are formed in the groove walls of the containing grooves. The clamping parts are used for extending into the containing holes to realize positioning; moreover, the inserting parts are connected with the side wall of the containing grooves through a fastener, so that the relative positions of the connecting parts and the side frame can be quickly positioned, and the mounting efficiency is improved.

Description

technical field [0001] The invention relates to the field of displays, in particular to a screen frame and a laser projection display device. Background technique [0002] With the continuous development of science and technology and the improvement of people's living standards, new laser projection display devices have been more and more widely used. [0003] At present, among the laser projection screens, the frame-type screen has the advantages of light weight, low cost, and easy assembly, and thus has been widely used. Among them, the frame-type screen is formed by splicing multiple side frames. figure 1 It is a structural schematic diagram of a framed screen in the prior art. like figure 1 As shown, specifically, when the side frames 10 are spliced ​​and connected, the two side frames 10 corresponding to the adjacent two sides of the screen are connected through the corner connectors 20 . Specifically, the corner connector 20 has two protruding parts 201 at right an...

Problems solved by technology

[0004] However, on the one hand, when aligning the side frame 20 or the through-hole connection holes provided on the extension part 201, it often takes multiple attempts to achieve accurate alignment, and after alignment, the relative position must be kept unchanged. For example, keep the state where the connector extends into the chute at this time until the fixing of the fastener is completed. On the other hand, usually in order to make the corner connector 20 and the side frame 10 assembled more firmly, it is necessary to set multiple pairs of connecting holes. Therefore, the above-mentioned installation process needs to be repeated many times, which makes the installation efficiency of the frame-type screen very low. Usually, the installation of one above-mentioned screen frame requires two people to cooperate for about 100 minutes. Self-installation
