Technical Field

[0001] This utility model belongs to the field of projection lamp lighting control technology, specifically a projection lamp lighting scene control device. Background Technology

[0002] A projector is an optical device that typically uses a high-brightness light source. Through the principles of optical refraction and lens imaging, it projects patterns or images onto surfaces such as walls and floors. It can be used for film and television playback, displaying advertisements, decorating the environment, or creating specific visual effects.

[0025] like Figures 1 to 3As shown, a fixing block 2 is fixedly connected to the side wall of the lifting platform 1; a fixing platform 21 is provided on the top of the fixing block 2; a lifting machine 22 is fixedly connected to the top of the fixing platform 21, and the output end of the lifting machine 22 is fixedly connected to the top of the fixing block 2; a limit rod 23 is fixedly connected to the top of the fixing block 2; a limit cylinder 24 is fixedly connected to the top of the fixing platform 21, and the limit cylinder 24 is positioned corresponding to the limit rod 23; a mounting hole 25 is provided on the top of the fixing platform 21; during operation, the user can use the mounting hole 25 to fix the fixing platform 21 in a predetermined position, thereby completing the overall operation of the device. At the same time, the user can adjust the output of the lifting machine 22 by driving the lifting machine 22. At this point, since the fixed block 2 and the output end of the elevator 22 are fixedly connected, the height of the fixed block 2 and the components connected to the fixed block 2 will change synchronously. The limiting rod 23 fixed to the top of the fixed block 2 contacts the inner wall of the limiting cylinder 24. The limiting rod 23 can limit the fixed block 2 by contacting the limiting cylinder 24.

During operation, the buffer ring 6 is fixedly connected to the side wall of the output end of the elevator 22. Whenever the fixed block 2 moves upward to a predetermined position under the action of the elevator 22, the buffer ring 6 fixedly connected to the output end of the elevator 22 will contact between the fixed block 2 and the fixed platform 21. Through the above structure, the buffer ring 6 is set to contact between the fixed block 2 and the fixed platform 21, thereby avoiding multiple first reinforcing blocks 5 from being squeezed at the bottom of the fixed platform 21, which is conducive to maintaining the stability of the components of the device and avoiding mutual squeezing and damage between the components.

Among them, the limiting rod 23 fixed to the top of the fixed block 2 contacts the inner wall of the limiting cylinder 24. The limiting rod 23 can contact the limiting cylinder 24. The fixed block 2 is limited by method 4. Whenever the movable block 14 moves to the predetermined position, the fixed protrusion 3 fixed to the side wall of the movable block 14 will contact the lifting car 1, and the positioning piece 31 fixed to the side wall of the fixed protrusion 3 will contact the limiting wheel 16. Through contact, the fixed protrusion 3 and the positioning piece 31 can limit the movement range of the movable block 14. The user can place the projection lamp inside the placement box 4 and fix the projection lamp with the help of the fixing piece 41 and its top opening. Multiple first reinforcing blocks 5 fixed between the lifting car 1 and the fixed block 2, and fixed to the movable block 14, are also included.
