Embodiment Construction

[0017] The specific content of the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0018] Such as figure 1 As shown, there is an anti-static projection screen. The bottom of the screen 1 is connected with a lower rod 9 that is longer in width than the screen 1. The lower rod 9 is made of a metal material.

[0019] The top of the screen 1 is fixedly connected to the reel 3, the reel 3 is located in the casing 2, and one end of the reel 3 is connected to the output shaft of the driving motor 6 through the coupling 4, and the driving motor 6 is connected to the power supply 5; When the motor 6 rotates, it can drive the reel 3 to rotate, thereby driving the curtain 1 to rewind or unwind.

[0020] Such as figure 2 As shown, the lower rod 9 is connected to the wall 7 through a connecting rod 8, and the connecting rod 8 is detachably connected to the lower rod 9,

[0021] The curtain fabric 1 includes a base body and an antista...

Abstract

The invention discloses an anti-static projection curtain. The bottom of the curtain is connected with a lower rod with the width larger than that of the curtain, the lower rod is made of metal materials, the top of the curtain is fixedly connected to a reel, the reel is located in a housing, one end of the reel is connected with an output shaft of a driving motor through a coupler, and the driving motor is connected with a power source. The driving motor can drive the reel to rotate when rotating so as to drive the curtain to be wound or unwound, the lower rod is connected with a wall throughthe connecting rod, the connecting rod is detachably connected with the lower rod, the curtain comprises a base body and an anti-static layer, and conductive yarn is evenly woven into the anti-staticlayer when the anti-static layer is woven. According to the invention, the lower rod at the bottom can prevent excessive winding and limit the curtain; meanwhile, the stability of the curtain can bekept when the curtain is lifted, and the curtain does not swing along with external force after the connecting rods are connected; and the anti-static layer can reduce dust adsorbed on the surface ofthe curtain.

Description

Technical field [0001] The invention belongs to the field of projection screen equipment, and particularly relates to an anti-static projection screen. Background technique [0002] Projection screens, used in conjunction with projectors, are used in movies, offices, home theaters, large conferences and other occasions. Tools used to display images and video files come in many specifications and sizes. Existing projection screens are prone to generate static electricity during winding, unwinding and use, which can attract dust and affect the projection effect; and because of the long thin cloth, it is easy to swing by external forces. Summary of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the technical problem to be solved by the present invention is that the existing projection screen is easy to generate static electricity during winding, unwinding and use, which will attract dust and affect the projection effect; and because it is a long ...
