Abstract

The invention discloses liftable multimedia projection equipment, and relates to the technical field of multimedia equipment. The equipment comprises a support frame and a projection equipment body, wherein a motor is mounted to the top surface of the support frame, and is connected to the support frame through a bolt, the output end of the motor is connected to a bevel gear I, a lifting box is mounted to the left side of the motor, a screw rod is mounted inside the lifting box, the bottom end of the screw rod is connected to a bevel gear II, and a moving seat is mounted on the surface of thescrew rod. According to the equipment, the motor drives the bevel gear I to rotate, the bevel gear I drives the bevel gear II and the screw rod to rotate, the moving seat pushes a fastening seat and acylinder box to move in the vertical direction, the cylinder drives a telescopic rod I to stretch and contract, the telescopic rod I pushes hinge seats on the left and right ends of the telescopic rod to move inwards or outwards simultaneously, a push rod pushes the hinge seat II and a base to ascend or descend, a hydraulic cylinder pushes the telescopic rod II and a pulley to move horizontally in a sliding rail, the pulley drives a cross lifting rod and a supporting plate to ascend or descend, thus realizing the height adjustment of the projection equipment.

Description

technical field [0001] The invention relates to the technical field of multimedia equipment, in particular to a liftable multimedia projection equipment. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen.
