[0002] At present, projection equipment is an important part of modern visual presentation technology. It has a profound technical background and is constantly innovating. With the rise of digital technology, projection equipment has entered the digital age. High-definition digital projectors use digital signal processing technology to present clearer and more realistic images. At the same time, the emergence of laser projectors has broken the limitations of traditional projection equipment. Laser light sources have higher brightness, more stable performance and longer service life, which significantly improves the projection effect.

[0003] In the prior art, there is an intelligent projection device with the authorization announcement number CN218208609U. The bottom end of the patented electric push rod is firmly connected to a connecting plate, and the bottom of the connecting plate is stably fixed to the top of the intelligent projection device body by bolts. It has a multi-angle adjustment function, which can ensure that the lens of the projection device body is accurately projected onto the screen. However, in scenes where promotional displays need to be quickly built, the projector cannot be installed quickly, which extends the preparation time and may also lead to reduced work efficiency. Operators may make installation errors due to improper operation or misunderstanding, which will not only affect the projection effect, but also may cause damage to the equipment.

[0021] See also Figure 1-3 A through slot is provided inside the sliding block 10, a connecting rod 13 passes through the through slot, a portion of the inclined sliding block 16 is slidably connected inside the straight slot, a portion of the sliding rod 15 is located inside the straight slot, a projection lamp 3 and a switch button 4 are respectively installed on one side of the projection body 1, a spring 15 is fixedly connected between the inclined sliding block 16 and the inner wall of the straight slot, and two symmetrically arranged circular holes are provided on the base 9, and the sliding rod 15 passes through the circular holes.

[0022] The specific implementation process of the utility model is as follows: first, the mounting base 7 is installed on the inner wall of the window by bolts, and then the dust shield 2 is installed on the fixing base 6 by fixing screws 12, and then the fixing block 11 is aligned with the circular groove on the base 9, and the fixing base 6 is pressed upward, and the fixing block 11 hits the inclined surface of the inclined slider 16 to move the inclined slider 16. When the inclined slider 16 enters the straight groove due to the ejection of the spring 15, the fixing block 11 enters the inner part of the circular groove, and then the rebound force of the spring 15 rebounds the inclined slider 16 to The bottom of the fixed block 11 is stuck to complete the installation. When disassembling, the fixed seat 6 is continued to be pressed upward, and the inclined surface of the inclined sliding block 16 hits the sliding block 10 to move the inclined sliding block 16. When the inclined sliding block 16 is ejected into the straight groove due to the spring 15, the sliding block 10 slides to the bottom of the fixed block and fits. At this time, the inclined sliding block 16 is at the bottom position of the sliding block 10. Then the fixed seat 6 is pulled out vertically downward. Due to the inclined surface setting of the inclined sliding block 17, the sliding block 10 and the fixed block 11 are moved out of the circular groove at the same time to complete the disassembly.

[0023] In addition, after the user aligns the threaded holes on the dust shield 2 with the threaded holes on the fixing seat, the user aligns the fixing screws with the four threaded holes, screws them in and tightens them, thereby completing the installation of the dust shield 2 .
