Projection system and projection screen supporting device

An adjusting device for a light-pipe includes an outer tube, a rotatable ball, an inner tube and an adjustment member. The inner tube is configured to accommodate the light-pipe. The outer tube comprises a first end and a second end disposed oppositely, and a receiving cavity constructed to receive the rotatable ball is formed in the first end of the outer tube. The rotatable ball is hinged in the receiving cavity, and a through-hole is opened in the rotatable ball. One end of the inner tube is fixedly connected to the through-hole, and the other end is disposed inside the second end of the outer tube through the adjustment member. The adjustment member is configured to drive the inner tube to swing along the center of the rotatable ball within the outer tube.

Adjusting device for light-pipe and projector

A wall-hung bracket for a projection screen is provided, including a guide rail, a slider and a lead screw. The guide rail is configured for being fixed on a wall along a vertical direction. The slider is slidingly connected to the guide rail. The slider is configured for being connected to a rear surface of a projection screen. The lead screw is provided with threads, and the lead screw is in threaded connection to the slider. When the lead screw rotates on its longitudinal axis, the slider slides in the vertical direction along the guide rail driven by the lead screw.
