Description
Technical Field
[0001] The utility model relates to the technical field of projectors, in particular to a rotatable circular projector. Background Art
[0002] With the continuous development of optical technology, the optical performance of circular projectors is constantly improving. For example, key indicators such as brightness, contrast, and resolution are constantly being optimized, providing users with clearer and more realistic projection images. High-brightness circular projectors can be used in brighter environments, broadening their use cases beyond darkroom environments.
[0003] Most existing projectors are square in design. Compared with circular projectors, square projectors have some disadvantages.

At the same time, the internal structure layout of existing square projectors is unreasonable, the light utilization rate is poor, and there are phenomena such as dark corners on the edges. To address the above problems, we have launched a rotatable circular projector. Utility Model Content

[0027] Reference Figure 1 - Figure 8In a preferred embodiment, by providing a storage mechanism, the sleeve 1 is rotated, and the sleeve 1 rotates on the outside of the support plate 14, so that the projection direction and angle of the lens body 10 can be adjusted.

[0029] Working principle: Through the provided storage mechanism, the sleeve 1 is rotated, and the sleeve 1 rotates on the outside of the support plate 14, so that the projection direction and angle of the lens body 10 can be adjusted.
