Novel dome screen

Abstract

The invention discloses a novel dome screen, and belongs to the technical field of dome screen projection. The dome screen comprises a dome screen body; the dome screen body is formed by splicing a plurality of keels, the keels comprise the transverse keels and the vertical keels, fastening assemblies are arranged between the transverse keels and the vertical keels, each fastening assembly comprises a transverse pull rod and an inclined pull rod, and each transverse pull rod is transversely arranged between every two adjacent vertical keels and connected with the corresponding vertical keel; the inclined pull rods are obliquely arranged between two adjacent transverse keels and vertical keels and are connected with the transverse keels and the vertical keels, disc connecting pieces are arranged at the joints of the transverse keels and the vertical keels, the disc connecting pieces are fixed on the vertical keels, a plurality of bolt holes are formed in the disc connecting pieces, andthe ends of the transverse pull rods and the inclined pull rods are in bolted connection with the disc connecting pieces. And the disc connecting pieces play a role in connection in the dome screen, so the connection tightness among all parts is enhanced, and the dome screen is more stable.

Description

Technical field[0001]The present application relates to the field of ball projection techniques, and in particular, there is a new type of ball.Background technique[0002]Ball projection technology is an emerging display technology that breaks the contraction of the projected image in the past. Ball projection techniques can be divided into projection and internal administration according to different projection methods. The screen of the internal voter is a spherical backdrop screen, which is placed on the projector to project an image into almost entire spherical screens, and the viewer can see the entire ball full of images. The intraudio curtain can be played either specialized video or plays ordinary videos and movies. The current ball is mainly divided into two kinds of hard-curtains and soft balls. Since there are many defects in soft balls, such as the projection screen shaking is unstable, the impact of the airflow is serious, so that the hard work is more widely used.[0003]...

AI Technical Summary

Problems solved by technology

The current dome screens are mainly divided into two types: hard dome screens and soft dome screens. Due to the many defects of soft dome screens, such as shaking and unstable projection images and being seriously affected by airflow, hard dome screens are more widely used.

[0003] However, the inventor found in the research process of this application that the existing dome screen structure is relatively simple, and the connection between various components is not stable, and it is prone to shaking after long-term use, resulting in a decrease in the stability of the dome screen. Lifespan is not high
