Description

Technical Field

[0001] This utility model relates to the field of visual communication technology, specifically to an adjustable projection device. Background Technology

[0002] Adjustable projection devices are projection equipment that can flexibly adapt to different usage scenarios and needs. They mainly consist of a projector unit, an adjustable stand, and a control system. The adjustable stand has multi-dimensional adjustment functions, enabling 360-degree horizontal rotation and precise vertical tilt angle control, allowing the projected image to be easily aligned with different projection surfaces. The control system is easy to operate, supporting both manual and remote control. Users can conveniently adjust parameters such as focus, resolution, image size, and color using a remote control or mobile application. This device can be widely used in home theaters to create an immersive viewing experience; in business office settings, it can meet the presentation needs of different meeting room layouts; and in the education field, it allows teachers to flexibly configure settings according to classroom space and teaching scenarios, facilitating diverse teaching activities.

[0003] Patent publication number CN212986539U discloses a vertical adjustable height projection device, including a projector and a screen mounting mechanism. The projector is mounted on the top of a support plate. Suspension frames are provided on both sides of the support plate. A vertical cylinder is provided in the middle of the suspension frames. Bolt holes are provided on the upper part of the vertical cylinder. An adjustment rod is inserted into the vertical cylinder. Multiple mounting holes are evenly distributed on the adjustment rod. The vertical cylinder and the adjustment rod are fixed in position by bolts. Multiple sets of clamping mechanisms are symmetrically arranged on both sides of the projector on the support plate.

[0004] To address the issue that existing projector mounts have fixed lengths and cannot adjust the projection height according to actual usage needs, current technology uses an adjusting rod that moves up and down within the vertical tube, along with bolts, to adjust the projection height. This approach better meets user requirements. However, it still suffers from limitations such as the inability to adjust the projector angle or protect the projector, resulting in limited practicality. Utility Model Content
