Embodiment 1

[0045] Such as figure 1 As shown, this embodiment provides a hanger for a visual teaching projector, including a mounting plate 1, a telescopic column and a clamping frame, and the fixed cylinder 2 at the upper end of the telescopic column is fixedly connected to the mounting plate 1, The telescopic tube 3 at the lower end of the telescopic column is fixedly connected with the clamping frame. The specific structure of the telescopic column is as follows:

[0046] Such as image 3 As shown, the telescopic cylinder 3 is telescopically connected in the fixed cylinder 2, and the fixed cylinder 2 and the telescopic cylinder 3 are connected through the transmission connection of the inner cylinder 4, and the inner cylinder 4 is rotatably connected in the fixed cylinder 2 through a bearing 19. The tube 3 is rotatably connected to the inside of the inner tube 4 through threads, and the telescopic tube 3 is stretched axially by rotating the inner tube 4 . Wherein the outer surface o...

Embodiment 2

[0056] The present invention also provides a hanger control method, which is applied to a hanger for a visual teaching projector in Embodiment 1, including the following steps:

[0057] S1: Put the projector on two sets of horizontal branch poles along the horizontal direction;

[0058] S2: The controller sends out instructions through the remote control to control the contraction of the two sets of second electric cylinders, and then clamps the projector in the water direction;

[0059] S3: The controller controls the two sets of third electric cylinders to contract through the remote control to clamp the projector in the vertical direction;

[0060] S4: According to actual needs, the controller sends an instruction through the remote control to control one of the first electric cylinders of the first electric cylinder group to expand and contract to adjust the inclination angle of the projector to achieve the optimal inclination angle;

[0061] S5: According to actual needs...

Abstract

The invention discloses a hanger for a visual teaching projector and a control method of the hanger. The hanger for the visual teaching projector comprises a mounting plate, a telescopic column and aclamping frame; a fixed cylinder at the upper end of the telescopic column is fixedly connected with the mounting plate; a telescopic cylinder at the lower end of the telescopic column is fixedly connected with the clamping frame; the clamping frame comprises a fixed plate, a rotating plate, an adjusting plate and clamping claws; the telescopic cylinder is fixedly connected to the upper surface ofthe fixed plate; the upper surface of the rotating plate is rotatably connected with the lower surface of the fixed plate; the upper surface of the adjusting plate is connected with the lower surfaceof the rotating plate through an adjusting mechanism; the lower surface of the adjusting plate is fixedly connected with the clamping claws; the adjusting mechanism comprises first electric cylinders; four first electric cylinders are arranged; cylinder seats of the first electric cylinders are fixedly connected with the rotating plate; and telescopic rods of the first electric cylinders are in swinging connection with the adjusting plate. According to the hanger for the visual teaching projector and the control method of the hanger, the lifting and automatic adjusting functions are increased, and meanwhile, the adaptability with different projectors is improved.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a hanger for a visual teaching projector and a control method for the hanger. Background technique [0002] Now classrooms are gradually developing like multimedia classrooms. In order to reduce the impact of chalk dust on the health of teachers and students, digital teaching is adopted in most cases. The most common of these is the projector, which is also one of the essential devices. In addition to being used for teaching, it can also be seen at any time in offices and academic exchanges. [0003] In order to avoid taking up space for projection, the projector is installed on the ceiling or roof of the room, so a projector hanger is required, and the hanger is also called hoisting, mounting bracket, etc. The hanger on the market includes a pull rod and a fixed frame, the upper end and the lower end of the pull rod are respectively fixedly connected with the top ...
