[0002] Projectors include the design and optimization of optical systems to achieve high-quality image projection. The key technologies include light source technology, such as traditional bulb light sources, LED light sources, and emerging laser light sources. Different light sources have different characteristics and advantages, and projection lens technology, which affects the clarity and distortion of the projected image. In addition, image processing technology is also crucial. Signal transmission technology ensures that image signals can be accurately and quickly transmitted to the projector for display. These background technologies cooperate with each other, continue to develop and improve, and promote the improvement of projector performance and the expansion of application scope.

[0003] After checking the announcement number: CN115016211A, a projector is disclosed. This technology discloses a housing, a light source module, an optical-mechanical module, a projection lens module and a composite heat dissipation module. The light source module can be arranged in the housing and provide an illumination beam. The optical-mechanical module can be arranged in the housing and used to convert the illumination beam into an image beam. The projection lens module can be used to project the image beam to form an image. The composite heat dissipation module can be arranged in the housing. The composite heat dissipation module may include: a base having at least one groove, at least one heat pipe, and a plurality of fins. At least one heat pipe may be partially arranged in at least one groove, and a plurality of fins may be arranged on at least one heat pipe, etc., which has the advantages of avoiding or reducing the space waste caused by the bend of the heat pipe, thereby achieving better heat dissipation efficiency in a limited space and other technical effects";

[0004] Regarding the above-mentioned related technologies, the inventor believes that most of the existing projectors do not have a lifting function after installation, which results in some angles being unable to be adjusted. Secondly, most of the existing projectors are not dustproof, and if dust is accumulated for a long time without cleaning, the internal parts will age and become easily damaged.

[0005] In view of the above-mentioned related technologies, the inventor believes that a projector lifting stand is needed to solve the above-mentioned problems. Utility Model Content

[0034] A chassis 5 is placed on the upper part of the lifting plate 4, and a projector body 3 is placed inside the chassis 5. A heat dissipation groove 24 is opened on the upper part of the chassis 5, and a heat dissipation fan 28 is installed inside the heat dissipation groove 24 to facilitate the heat dissipation of the projector. One side of the chassis 5 is coated with a magnetic coating 25, and a baffle 26 is placed at the front opening of the chassis 5 and is made of iron. A glass plate 27 is arranged inside the baffle 26, which can prevent dust without affecting the normal use of the projector. The baffle 26 is adsorbed on the chassis 5 through the magnetic coating 25, and a circular groove 21 is opened on one side of the baffle 26, and the baffle 26 can be removed or installed through the circular groove 21. Anti-slip strips 23 are arranged at the front and rear ends of the chassis 5, and the two anti-slip strips 23 are fixedly connected to the lifting plate 4. The upper part of the lifting plate 4 is fixedly connected to the lifting device 2.

[0035] The lifting device 2 includes a motor 18, a fixed block 14 and a bidirectional threaded rod 12. The fixed block 14 is connected to the baffle 26. Two rotating rods 13 are arranged inside the fixed block 14. The two rotating rods 13 are distributed in a mirror image. The lower parts of the two rotating rods 13 are rotatably connected to the inside of the fixed block 14. Two moving blocks 11 are arranged on the upper parts of the two rotating rods 13. The interiors of the two moving blocks 11 are rotatably connected to the upper parts of the rotating rods 13. The bidirectional threaded rod 12 is engraved with threads in different directions and is threadedly sleeved with one moving block 11 respectively. A long groove 19 is opened on the upper part of the support frame 1. The two ends of the long groove 19 are rotatably connected to the threaded rod.
