Abstract
The invention relates to a 360-degree projection lens comprising a rotating assembly and a fixed assembly. The rotating assembly comprises a mirror bracket. A front lens group is arranged inside a front lens cone. A mirror is arranged on the inner side of the mirror bracket. The front end of a rear lens cone II sleeves the rear end of a rear lens cone I. The radial wall of the rear lens cone I is provided with circular slots at the joints of the rear lens cone I and the rear lens cone II. The wall of the rear lens cone II is provided with connecting holes in positions corresponding to the circular slots. The rotating assembly is connected with the fixed assembly through connecting screws arranged in the connecting holes and the circular slots. Each connecting screw includes a rotating cap and a connecting end. The upper threaded sections of the connecting screws are in matching connection with the connecting holes of the fixed assembly. The front lens group can rotate 360 degrees. The lens is easy to adjust. A projector machine can be always placed horizontally.
