Description

Technical Field

[0001] The utility model belongs to the technical field of projection hard screen frames, and in particular relates to a multi-purpose frame structure of a projection hard screen. Background Art

[0002] With the improvement of living standards, projection hard screens have entered thousands of households, and the visual effects and appearance of the screens have gradually been valued by users. The frames of the projection hard screens currently on the market are beveled and spliced, which easily produce gaps and sharp edges that can easily cut people. In addition, the installation method of the hard screen is to match the mounting hangers installed on the wall with the mounting parts fixed on the back of the screen. The mounting parts themselves have a certain thickness, so the back of the hard screen will be a certain distance from the wall after installation, resulting in gaps and affecting the stability of the installation. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a multi-purpose frame structure of a projection hard screen.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A multi-purpose frame structure for a projection hard screen comprises a projection hard screen, wherein an upper frame and a lower frame are installed on the upper and lower sides of the projection hard screen, and the size and structure of the upper frame and the lower frame are the same; a left frame and a right frame are installed on the left and right sides of the projection hard screen, and the size and structure of the left frame and the right frame are the same; arc locking blocks are provided at the left and right ends of the upper and lower frames, and fixing screws are installed in the arc locking blocks; threaded holes matching the fixing screws are provided on the upper and lower sides of the left and right frames, and arcs matching the shape of the arc locking blocks are also provided on the outer sides of the left and right frames; the upper and lower frames are also provided with long grooves, and mounting parts are also installed in the long grooves.

[0006] It is further defined that the upper frame and the lower frame are integrally formed with the arc locking blocks at the left and right ends. Such a structural design is easy to produce and has high connection strength.

[0007] It is further defined that the upper frame, the lower frame, the left frame and the right frame are all provided with mounting slots, and the outer periphery of the projection hard screen is mounted in the mounting slots. Such a structural design facilitates the fixed positioning installation of the projection hard screen.

[0008] It is further defined that the backs of the upper frame, the lower frame, the left frame and the right frame are all provided with a plurality of locking screws, and the upper frame, the lower frame, the left frame and the right frame are locked and connected with the projection hard screen through the locking screws. Such a structural design improves the fixed installation effect of the projection hard screen.

[0009] The beneficial effects of the utility model are as follows: in order to avoid splicing misalignment and sharp edges in the frame, the end portions of the upper frame, lower frame, left frame and right frame of the projection hard screen are designed to have arc edges and match each other, and are fixed with screws, which can not only solve the splicing gap but also avoid the occurrence of sharp edges. At the same time, in addition to the normal fixing to cover the edge of the screen and solve the splicing problem, the upper frame is also provided with a long groove on the lower side for hanging the mounting part, so that after the projection hard screen is installed, the back of the projection hard screen is close to the wall, thereby improving the stability of the installation.
