Multifunctional projector structure

Abstract

The invention discloses a multifunctional projector structure which comprises a joint connector and an up-and-down adjustment device, wherein the joint connector is composed of a joint part and a driving connection part, and the up-and-down adjustment device is arranged on the left side of the joint connector. The joint part is internally provided with a locking cavity, the central position of the locking cavity is provided with a fixed connection block with the front end and the rear end fixedly connected with the joint part respectively, the end face of the right side of the fixed connection block is provided with a binding post, the outer side of the fixed connection block is slidably connected with a locking sliding component, the locking sliding component is provided with a first threaded rod in threaded matched connection, the first threaded rod extends towards the two sides, locking sliding cavities are symmetrically disposed on two groups of struts on the right side of the locking sliding component, clamping teeth devices are arranged on the opposite sides of the two groups of locking sliding cavities, and the inner wall of the joint part on the right side of the locking cavity is provided with a guide connection port communicated with the locking cavity. The multifunctional projector structure is simple in structure, can be automatically fixedly connected and is high in safety and joint reliability and stability, and the height is adjustable.

Description

technical field [0001] The invention relates to the field of projectors, in particular to a multifunctional projector structure. Background technique [0002] The application of projectors has become very popular. For projectors used indoors, the projector is usually installed under the suspended ceiling of a building through a suspension bracket. The traditional suspension bracket used to install the projector is mainly composed of a fixed seat, a height adjustment device, a positioning device and a suspension claw. It has the disadvantages of complex structure and high manufacturing cost, and is not easy to disassemble. The working height should match the height of the projection cloth. Therefore, the projector hanger has a certain height. If it is often hung on the ceiling, it will seriously affect the movement of people in the room and there is also the problem of poor stability after fixing.
