DETAILED DESCRIPTION

[0019] like Figures 1 to 3 As shown, a projection lamp includes a projection body 10 and a mounting bracket 20, wherein the projection body 10 can be adjustably mounted on the mounting bracket 20. When in use, the mounting bracket 20 is mounted on a projection device bracket. The projection body 10 can be swung along the mounting bracket 20 according to the user's usage requirements, thereby achieving an effect of adjusting the projection angle.

[0020] During the specific implementation, a heat dissipation bracket 11 is provided at the rear of the projection body 10, and a heat dissipation fan 12 is provided at the rear of the heat dissipation bracket 11. The heat dissipation fan 12 is connected to the projection body 10 by wires, and a fan cover 13 is provided on the outer side of the heat dissipation fan 12. A plurality of connecting studs 111 with internal threads are provided on the inner side of the heat dissipation bracket 11. A plurality of connecting through holes 121 are provided at the edge of the heat dissipation fan 12, and a plurality of fixing through holes 131 are provided on the surface of the fan cover 13. The fixing through holes 131, the connecting through holes 121 and the connecting studs 111 correspond to each other one by one, and are connected and fixed by fasteners passing through the fixing through holes 131 and the connecting through holes 121 and the connecting studs 111 through threaded cooperation, so that the heat dissipation fan 12 and the fan cover 13 are respectively fixedly installed at the rear of the heat dissipation bracket 11, and the structure is simple and the installation is convenient.

[0021] When in use, when the projection body 10 is working in projection, the projection body 10 itself will generate a certain amount of heat. The heat dissipation bracket 11 is made of metal material. Through the design of the heat dissipation bracket 11, the heat generated by the projection body 10 can be transferred to the heat dissipation bracket 11 for heat dissipation. At the same time, the projection body 10 can drive the heat dissipation fan 12 to rotate and generate wind, so that the heat dissipation fan 12 cooperates with the heat dissipation bracket 11 to achieve the effect of rapid heat dissipation, ensuring that the projection body 10 maintains a stable temperature during use. This design not only ensures the stability of the projection body 10 during use, but also improves its service life. Effective heat dissipation can reduce damage to components and performance degradation, thereby extending the life of the projection equipment.

[0022] During the specific implementation, the left and right sides of the projection body 10 are symmetrically recessed with mounting grooves 14, and the two mounting grooves 14 are respectively connected with mounting slide blocks 15, and the surface of the mounting slide blocks 15 is provided with a plurality of threaded mounting through holes 151, and the upper surfaces of the left and right sides of the mounting bracket 20 are symmetrically provided with adjustment through holes 21, and the two sides of the mounting bracket 20 are respectively provided with fixing components 30, and one end of the fixing component 30 is provided with a threaded fixing stud 31, and the fixing stud 31 is connected and fixed by threaded cooperation between the adjusting through hole 21 and the mounting through hole 151, so that the projection body 10 and the mounting bracket 20 can be swingably adjusted. When it is necessary to adjust the use angle of the projection body 10, first loosen the fixing components 30 respectively, so that the projection body 10 can swing along the upper part of the mounting bracket 20, so as to adjust the use angle, and then tighten the fixing components 30 to fix the projection body 10 at the required angle. This design makes the connection between the projection body 10 and the mounting bracket 20 adjustable, and the user can flexibly adjust the projection angle according to needs, so that the projection effect is more satisfactory, and the structure is simple, which is convenient for users to adjust.

[0023] The plurality of mounting through holes 151 include a bracket through hole 151a and two locking through holes 151b. The bracket through hole 151a is arranged between the two locking through holes 151b. The adjustment through hole 21 corresponds to the bracket through hole 151a. The fixing stud 31 is threadedly connected with the bracket through hole 151a through the adjustment through hole 21, thereby making the projection body 10 and the mounting bracket 20 adjustable and connected, and the installation is simple and convenient.

[0024] The size of the mounting slot 14 is larger than the size of the mounting slide block 15, so that the mounting slide block 15 can be slidably adjusted and connected in the mounting slot 14, and is connected in the locking through hole 151b and abuts against the mounting slot 14 through the threaded fit of the fastener, so that the mounting slide block 15 is fixed in the mounting slot 14. When in use, the user can unscrew the fastener used for fixing, so that the mounting slide block 15 can slide in the mounting slot 14, thereby adjusting the position. After the adjustment is completed, the user tightens the fastener to ensure that the position of the mounting slide block 15 does not change. Through such a design, the user can easily adjust the position of the mounting slide block 15, and at the same time drive the mounting bracket 20 to adjust the position to meet the projection requirements at different angles.

[0025] In summary, the rear of the projection body 10 is provided with a heat dissipation bracket 11, the rear of the heat dissipation bracket 11 is provided with a heat dissipation fan 12, and the outer cover of the heat dissipation fan 12 is provided with a fan cover 13. The two sides of the projection body 10 are symmetrically recessed with mounting slots 14, and the two mounting slots 14 are respectively connected with mounting sliders 15. The two sides of the mounting bracket 20 are respectively provided with fixing components 30, and the mounting bracket 20 and the projection body 10 are connected by the fixing components 30, so that the projection body 10 and the mounting bracket 20 can be swingably adjusted.
