Embodiment Construction

[0013] The present invention will be further described below through specific embodiments, but it should not be construed as a limitation of the present invention. Those skilled in the art may also make various modifications, replacements, and changes based on the above solutions. All modifications, replacements and changes made based on the above-mentioned technical ideas belong to the scope of the present invention.

[0014] Most of the traditional picture frame curtains are directly hung on the frame with springs. The surrounding of the curtain is subjected to spring tension from multiple points, and the force is uneven. After a long time of use, it is prone to wrinkles, which will affect the imaging quality of the picture. The improvement of the present invention is that, as figure 1 , figure 2 As shown, a support rod 3 is provided around the curtain 2, and the support rod 3 should run through the entire side length of the curtain 2, and a plurality of elastic members 4...

Abstract

The invention discloses a crease-free picture frame screen with a hidden spring belonging to the technical field of projection display. The picture frame screen comprises a frame and a screen, wherein the screen is arranged on the surface of the frame; support rods are arranged at the periphery of the screen and run through the overall edge length of the screen; a plurality of elastic parts are evenly distributed on the support rods; one end of each elastic part is connected with the corresponding support rod and the other end is connected with the frame; and a picture frame is also arranged at the periphery of the frame, wraps the periphery of the screen and the elastic parts, and is arranged on the frame in a clamping manner. The crease-free picture frame screen has the beneficial effects that the support rods are arranged at the periphery of the screen, and the elasticity of the elastic parts is evenly dispersed to the periphery of the screen, so that the curtain has constant, lasting and uniform tension and is kept in a flat state for a long period of time; no crease appears in the screen surface; an image can be displayed under an ultra-short focus projection in an undistorted manner; the front surface and the rear surface of the screen are clean and tidy in structure; and the elastic parts or other point bulges are not exposed, so that a user can be prevented from being scratched.

Description

technical field [0001] The invention relates to the technical field of projection display, in particular to a wrinkle-free picture frame screen with hidden springs. Background technique [0002] At present, the projection screens on the market can be divided into electric retractable screens, electric pull screens, picture frame screens, manual screens and so on in terms of structure. Among them, the picture frame screen generally adopts a frame with a width of about 6cm, and the screen is around the back of the picture frame. It is fixed by the tensioning method of elastic elements such as exposed springs and rubber bands. The wider frame only provides a shielding function for the exposed springs around the curtain on the front, or the curtain is wrapped outside the supporting frame by the method of back Velcro. And install narrow decorative strips around to achieve a borderless or narrow border appearance. However, the screens with these structures all have problems such ...
