TECHNICAL FIELD
[0001] The utility model relates to multimedia projection equipment adjusting installation technical field, especially in kind of adjustable formula placing box for multimedia projection equipment. BACKGROUND
[0002] Multimedia projection equipment adjusting placing box is an innovative packing box design, which not only serves as a packaging container for projection equipment, but also has the function of adjusting the projection angle of the projection equipment.
[0003] The current multimedia projection equipment adjusting placing box in practical application generally uses universal joints and other angle adjusters to realize the angle adjustment of the projection equipment. However, this method has a significant disadvantage, that is, after adjusting the angle, the equipment is often not stable enough and is easy to deviate from the preset position due to slight touching or vibration, affecting the projection effect.
[0004] In order to overcome this instability, some placing box designs use relatively complex stabilizing mechanisms. These stabilizing mechanisms provide additional support and fixation by covering the projection equipment, thereby ensuring that the equipment remains stable after adjusting the angle. However, this approach has another problem: poor heat dissipation. Since the stabilizing mechanism often wraps the projection equipment quite tightly, it is difficult for the heat inside the equipment to be effectively dissipated, thereby affecting its long-term operation stability and service life.

The heat-dissipating storage box 9 is equipped with a multimedia projection device. Through the coordinated work of the first adjustment frame 2, the second adjustment frame 3, the position adjustment block 5, and the fastener 4, the angle of the heat-dissipating storage box 9 can be easily adjusted, so that the operator can conveniently adjust the multimedia projection device according to the specific conditions of the building to achieve the best projection effect.
[0029] The heat dissipation storage box 9 has heat dissipation channels 10 on its side walls and bottom. Multiple sliding adjustment bars 11 are connected to the bottom heat dissipation channel 10. A heat-conducting strip 12 is located at the upper end of each sliding adjustment bar 11. Multiple through holes 13 are provided on both the heat-conducting strip 12 and the sliding adjustment bar 11, and a heat-conducting sleeve 15 is inserted into each through hole 13. A heat dissipation fin 14 is located at the lower end of the heat-conducting sleeve 15, and a fastening bolt 16 is inserted into the lower end of the heat-conducting sleeve 15. The fastening bolt 16 is inserted into the through hole 13 and fitted with a fastening nut 17, thus fixing the heat dissipation fin 14 and the heat-conducting strip 12 to the sliding adjustment bar 11.

[0030] The sliding adjustment bar 11 has sliders at both ends, with screw holes on the sliders. The bottom of the heat-dissipating storage box 9 has multiple corresponding holes.

Fastening bolts 16 are inserted into the housing of the multimedia projection device and fixed by fastening nuts 17 to ensure the stability and heat dissipation efficiency of the device. Slider blocks are designed at both ends of the sliding adjustment bar 11, with corresponding holes at the bottom of the heat dissipation storage box 9. Bolts are inserted by aligning the screw holes on the sliders with the corresponding holes on the bottom of the heat dissipation storage box 9 to ensure a secure fixation. Anti-slip rubber pads are installed between the protrusion 8 and the heat dissipation storage box 9 to increase friction and provide cushioning. Position adjustment block 5 is fixed to the second adjustment frame 3 by bolts and slides along it to adjust its position to accommodate different angle adjustment needs.
[0035] Angle Adjustment Process: Loosen the fasteners 4 connecting the first adjustment frame 2 and the second adjustment frame 3.
