Description

Technical Field

[0001] This utility model relates to the field of suspended projector technology, specifically a suspended multi-dimensional adjustable projector. Background Technology

[0002] Wall-mounted projectors are widely used in education, offices, and home theaters due to their space-saving and flexible installation features. However, once installed, the projection direction and angle of existing wall-mounted projectors are usually fixed, making it difficult to adjust them flexibly according to actual usage needs. Adjusting the position of the projected image often requires manually adjusting the projector using tools such as ladders, which is cumbersome and poses safety hazards, especially in scenarios where the projector is installed at height.

[0003] In addition, the lenses of traditional wall-mounted projectors are exposed to the external environment for a long time, which easily accumulates dust and requires frequent maintenance. This not only affects the clarity of the projected image, but may also damage the optical performance of the lens, increasing maintenance costs and the burden of use.

[0004] To address this, we propose a suspended, multi-dimensional adjustable projector. Utility Model Content
