[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: A portable projection device for cultural media promotion includes a storage box 1, with a sealing cover 2 snapped onto the top of the storage box 1, and the sealing cover 2 and the storage box 1 are detachably connected; the storage box 1 has irregularly shaped and symmetrically distributed storage slots 3 inside, and symmetrically distributed support structures are snapped onto the storage slots 3, the support structures including a first guide rail 4 and a second guide rail 5 located inside the storage slots 3, and the ends of the first guide rail 4 and the second guide rail 5 are rotatably connected to each other; the first guide rail 4 and the second guide rail 5 are each provided with a positioning groove 6 on the same side, and the first guide rail 4... The positioning grooves 6 on the second guide rail 5 are spliced ​​together to form a whole; the second guide rail 5 has a mounting groove 7 on one side, and the mounting groove 7 extends to the end of the first guide rail 4 near the second guide rail 5, and a positioning strip 8 is slidably connected inside the mounting groove 7, while the positioning strip 8 extends to the inside of one side of the first guide rail 4; the storage slot 3 has symmetrically distributed mounting seats 9 fixedly connected inside, and each mounting seat 9 is rotatably connected to the lower end of the first guide rail 4; the storage box 1 has two symmetrically distributed speakers 10 inside, and the storage slot 3 also has a projector body 11 and a self-tightening screw 12 engaged inside.

[0026] The sealing cover 2 on the top of the storage box 1 needs to be opened to separate the sealing cover 2 from the storage box 1. The storage slot 3 has a symmetrically distributed support structure inside, including a first guide rail 4 and a second guide rail 5. First, rotate the first guide rail 4 to rotate around the fixed point of the mounting base 9 until the first guide rail 4 is perpendicular to the storage box 1.

[0027] After the first guide rail 4 is adjusted to a vertical position, the second guide rail 5 is rotated around the upper end of the first guide rail 4 until the first guide rail 4 and the second guide rail 5 are aligned. The positioning strip 8 in the mounting groove 7 is then moved downwards to a position between the first guide rail 4 and the second guide rail 5. The positioning strip 8 secures the connection between the first guide rail 4 and the second guide rail 5, preventing relative rotation. After completing the above steps, the overall support structure is as follows: Figure 4 As shown, a stable frame structure is formed, while the storage box 1 serves as a base to provide sufficient support.

[0028] Take out the projector body 11 from the storage slot 3 and install it between the overall frame structure formed by the first guide rail 4 and the second guide rail 5. The projector body 11 has sliders 13 on both sides. The sliders 13 can slide up and down inside the guide rail to adjust the height of the projector. In this way, the height of the projected image can be adjusted according to actual needs.

[0029] Example 2: Based on Example 1, the following structure is also disclosed: both ends of the projector body 11 are rotatably connected to sliders 13, and the connection between the sliders 13 and the projector body 11 is damped, and the self-tightening screws 12 are rotatably connected to the inside of the sliders 13; both sides of the storage box 1 are fixedly connected to two symmetrical mounting blocks 14, and the two mounting blocks 14 are rotatably connected to a handle 15, and the handle 15 is located on the top of the sealing cover 2.

[0030] The projector body 11 is connected to the guide rail at both ends via sliders 13. The sliders 13 and the projector body 11 are rotatably connected and damped, allowing the user to easily rotate the projector body 11 during adjustment to adjust its angle between the sliders 13.

[0031] After the height of the projector body 11 is adjusted, the slider 13 can be fixed by using the self-tightening screw 12. The self-tightening screw 12 is screwed into the slider 13, and the other end of the screw is inserted into the positioning groove 6 on the guide rail. The pressure between the screw and the positioning groove 6 will firmly fix the slider 13 inside the first guide rail 4 and the second guide rail 5, thereby ensuring that the height and angle of the projector body 11 no longer change.

[0032] After use, the projector body 11 can be easily stored. First, remove the self-tightening screw 12 from the fixing slider 13. Then, remove the projector body 11 from the guide rail structure and place it and the self-tightening screw 12 into the storage slot 3. Slide the positioning bar 8 to disengage it from the first guide rail 4. Rotate the first guide rail 4 around the mounting base 9, while simultaneously rotating the second guide rail 5 around the upper end of the first guide rail 4, so that the two are completely aligned and parallel. Continue rotating the first guide rail 4 until the entire support structure is stored inside the storage slot 3.

[0033] The storage box 1 has symmetrical mounting blocks 14 fixedly connected to both sides. The mounting blocks 14 are connected by a handle 15. When the device needs to be moved or carried, the device can be easily lifted by the handle 15, thereby improving portability.
