[0022] Reference Figures 1-6 A cushioning component for use in a paper-plastic packaging box for a printer, comprising:
[0023] The box body 1 has multiple foam boards 25 fixedly connected to its side wall. The multiple foam boards 25 can reduce the damage caused by collision or squeezing during the transportation of the printer and have a good protective effect. Two cover plates 2 are rotatably connected to the upper side of the box body 1. One of the cover plates 2 has a baffle 23 slidably connected to its side wall. A compression spring 24 is fixedly connected between the baffle 23 and the cover plate 2. The lower side of the baffle 23 is inclined. When the cover plate 2 is pressed down, it can directly squeeze the baffle 23 to slide inward. After the cover plate 2 is closed, it pops out again to lock the other cover plate 2, and the fixation is completed. When it is necessary to open, the baffle 23 can be pulled to slide inward. Two fixing rods 3 are fixedly connected inside the box body 1. Two buffer pads 4 are slidably connected to the outside of the two fixing rods 3.
[0024] A movable structure is installed on the housing 1. The movable structure includes two bidirectional screws 5 rotatably connected to the side wall of the housing 1. Both bidirectional screws 5 are threadedly connected to two buffer pads 4. The bidirectional screws 5 can drive the two buffer pads 4 to move inward or outward simultaneously. A spur gear 6 is fixedly sleeved on the outer side of each of the two bidirectional screws 5. A rotating shaft 7 is rotatably connected to the side wall of the housing 1. A spur gear 8 is fixedly sleeved on the outer side of the rotating shaft 7. Both spur gears 6 mesh with spur gear 8. A knob 9 is fixedly sleeved on the outer side of the rotating shaft 7. An auxiliary component is also installed on the buffer pad 4. The auxiliary component includes two fixed plates 10 fixedly connected to the upper side of the buffer pad 4. Two buffer springs 11 are fixedly connected to the side walls of the two fixed plates 10. One end of the two buffer springs 11 is fixedly connected to a buffer plate 12.
[0025] A pressure fine-tuning structure is installed on the buffer pad 4. The pressure fine-tuning structure includes two sliders 13 slidably connected to the side wall of the buffer pad 4. A movable plate 14 is fixedly connected to the upper side of the two sliders 13. Two buffer springs 15 are fixedly connected to the side wall of the movable plate 14. A buffer plate 16 is fixedly connected to one end of the two buffer springs 15. A rotating shaft 17 is rotatably connected to the side wall of the fixed plate 10. A spur gear 18 is fixedly sleeved on the outside of the rotating shaft 17. A rack 19 is slidably connected to the side wall of the buffer pad 4. The rack 19 is fixedly connected to the sliders 13. The spur gear 18 meshes with the rack 19. A knob 20 is fixedly sleeved on the outside of the rotating shaft 17. A locking assembly for controlling the rotation of the spur gear 18 is also installed on the fixed plate 10. The locking assembly includes a stop bar 21 slidably connected to the side wall of the fixed plate 10. A compression spring 22 is fixedly connected between the stop bar 21 and the fixed plate 10.
[0026] In this invention, firstly, the operator places the printer into the housing 1. By rotating knob 9, knob 9 drives spur gear 8 via shaft 7. Spur gear 8 drives two double-acting screws 5 via spur gear 6, thereby moving two buffer pads 4 inward. This allows the buffer pads 4 to adapt to printers of different sizes. The printer is also secured by buffer spring 11 and buffer plate 12, preventing damage to the packaging during transport and reducing damage to the printer from impacts. After the buffer pads 4 are in their fixed positions, the stop lever 21 is pulled upward to prevent it from moving further. The rotation of spur gear 18 is blocked. At this time, spur gear 18 can be rotated by turning knob 20. Spur gear 18 drives slider 13 to move through rack 19. The movement of slider 13 drives moving plate 14, so that buffer plate 16 can be fixed to the printer. The elasticity of buffer spring 25 avoids the damage that may be caused by shaking when directly touching. While fixing, the reserved spring pressure reduces the impact force caused by shaking. After fixing, release the stop bar 21 so that the stop bar 21 is locked between the two teeth of spur gear 18. The locking component ensures that the buffer will not loosen or be over-compressed during transportation.
