Abstract

The invention relates to a folding type projector suspension bracket. The folding type projector suspension bracket includes a ceiling, two moving contraction devices are symmetrically mounted under the ceiling, and a T-shaped mounting table is mounted in the middle of the ceiling; a scissor fork type lifting frame is mounted on the T-shaped mounting table; the lower end of the scissor fork type lifting frame is mounted on a limiting plate; a lower end face of the limiting plate is also provided with a projector support; two sides of the projector support are connected with two sides of the ceiling through two flexible skirt edges respectively; each moving contraction device includes two support tables, a lead screw is mounted between the support tables through a bearing; the right end of the lead screw is connected with a drive motor through a coupling; the drive motor is mounted under the ceiling; an outer wall of the lead screw is connected with a lead screw nut; an outer side of the lead screw nut is mounted on a sliding block; an annular limiting block mounts the lead screw nut on the sliding block through a screw; and a winding rope penetrates through a Number one hanger to be connected with the scissor fork type lifting frame. The folding type projector suspension bracket provided by the invention can realize a folding contraction function, and has the advantages of simple structure, good contraction performance and the like.

Description

technical field [0001] The invention relates to projection equipment, in particular to a foldable projector hanger for fixing a projector. Background technique [0002] With the rapid development of modern information processing technology, the requirements for the modernization of conference rooms are getting higher and higher. Therefore, the conference room has gradually evolved from a purely listening, hearing and communication place to a comprehensive multi-functional A large number of electronic equipment such as slide projectors, projectors, video recording and playback equipment, and sound reinforcement equipment have entered the meeting place, making the configuration of the conference system more and more professional and more powerful. [0003] Since the working height of the existing projector needs to match the height of the projection cloth, a projector hanger is generally required; and the projector hanger has a certain height, if it is often hung on the ceilin...
