Description

Technical Field

[0001] The utility model relates to the technical field of projection suspension, in particular to a projection suspension structure for computer classroom teaching. Background Art

[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. When teaching in a computer classroom, the projector will be hung on the top wall of the computer classroom. This hanging structure is used to hang the projector.

[0003] When the projector is in use, the projector will be connected to the ceiling wall of the classroom through a hanging structure. Due to the simplicity of the hanging structure, screws are inserted through preset screw holes, one end is connected to the ceiling wall of the classroom, and the other end is connected to the end wall of the projector, which serves the purpose of simple connection. However, since a wiring harness will be arranged on the projector, the wiring harness hangs on the outside of the projector, which is extremely unsightly. At the same time, the excessive exposure of the rubber outer layer of the wiring harness also poses a risk of skin breakage. Utility Model Content

Through holes for inserting cables are provided at the upper and lower end side walls of the fixing column. Buckles are fixed at the upper and lower end side walls of the fixing column. A movable column is installed at the side end of the fixing column. Column cavities for cable arrangement are provided inside the movable column and the fixed column.

[0007] Preferably, two fixing plates, screw seats and rubber pads are provided, so that when the fixing plates are positioned and in contact with the fixing surface, the screw seats rotate and protrude outward from the end surface of the fixing plate, and the rubber pads contact with the fixing surface.

[0008] Preferably, the screw holes are symmetrically distributed about the center of the fixing plate, one fixing plate is fixedly connected to the projector through the screw holes through the screws, and the other fixing plate is connected to the classroom wall ceiling through the screw holes through the screws.

[0009] Preferably, a slide groove is provided at the end wall of one side of the fixed plate close to the movable column, and a slide rail fixed to the movable column is provided in the slide groove. The slide rail can slide sideways along the length direction of the slide groove, so that the movable column can move and approach or move away from the fixed column, and then be snap-connected or disassembled.

[0010] Preferably, the side walls at the upper and lower ends of the fixed column are provided with snap-fitting holes for engaging with the snap buckles, so that the fixed column and the movable column can be detachably assembled together.
