Description

Technical Field

[0001] This utility model belongs to the technical field of packaging boxes, specifically relating to a bakelite packaging box with a foldable moisture-proof base. Background Technology

[0002] Phenolic revetment crates are packaging containers made of phenolic resin, primarily used for transporting and storing various goods. Phenolic revetment is a composite material made from wood fibers and synthetic resins through high-temperature and high-pressure processing. It combines the toughness of wood with the corrosion resistance of plastics, thus exhibiting excellent performance in terms of moisture resistance, mildew resistance, and acid and alkali resistance. These crates are typically sturdy and can withstand significant weight and impact, making them suitable for long-distance transport of industrial equipment, precision instruments, or fragile items. Compared to ordinary wooden crates, phenolic revetment crates have a longer service life and are less susceptible to deformation or cracking due to environmental humidity. In fields with high packaging requirements, such as the military, electronics, or chemical industries, phenolic revetment crates are widely used due to their stability and reliability. Phenolic revetment crates are generally placed on the ground via a base, with the base directly in contact with the ground.

[0003] However, the height of the base installed at the bottom of existing bakelite packaging boxes is generally limited. When there is water accumulation on the ground, the outer box and base of the bakelite packaging box are prone to getting damp. Over time, they may even rot, which will damage the outer box and base of the bakelite packaging box. This may affect the contents of the packaged items inside the wooden packaging box and reduce the service life of the bakelite packaging box. Utility Model Content

[0013] Compared with the prior art, this utility model provides a bakelite packaging box with a foldable moisture-proof base, which has the following beneficial effects:

[0014] 1. Through the configuration of an outer support frame, inner support frame, sliding threaded block, fixed block, pallet base, lead screw, crank handle, grip, connecting rod, pulley, slide rail, and welding plate, the operator only needs to rotate the grip to drive the lead screw to rotate, causing the sliding threaded block to move axially. Then, the connecting rod pulls the inner and outer support frames to achieve synchronous lifting. This design allows the pallet base to be lifted smoothly, keeping the bakelite packaging box away from the damp environment of the ground and effectively extending its service life. The unique four-link lifting structure, combined with the pulley and slide rail system, not only ensures the stability and synchronization of the lifting process, but also makes the operation labor-saving and reliable. The welded and fixed support feet and base frame further enhance the rigidity of the overall structure, completely avoiding the tilting problem that may occur during the lifting process.

[0015] 2. During descent, rotating the handle in the opposite direction will allow the pallet base to fall smoothly back down. The precision pulley and slide system ensures smooth and accurate movement trajectory, while the sturdy support structure remains stable at all times, effectively preventing positional deviation. When fully folded, this design facilitates both overall transportation and easy access to items inside the packaging box. The entire mechanism operates smoothly and provides stable support.

A connecting rod 9 is provided between the inner support frame 8 and the outer support frame 7. A screw rod 13 is provided between the sliding threaded block 10 and the fixing block 15. A crank handle 14 is provided at one end of the screw rod 13. A handle 4 is provided on the crank handle 14.

[0024] In this embodiment, the bakelite packaging box is a packaging container made of bakelite material, mainly used for transporting and storing various items. Bakelite is a composite material made of wood fiber and synthetic resin through high temperature and high pressure treatment. This type of packaging box is usually sturdy and can withstand a large weight and impact, making it suitable for long-distance transportation of industrial equipment, precision instruments, or fragile items. The bakelite packaging box 1 can achieve height adjustment of the pallet base 2 through the linkage structure of the outer support frame 7, inner support frame 8, pulley 11, and slide rail 12, combined with the sliding threaded block 10 mechanism driven by the screw 13. Rotating the handle 4 drives the screw 13 to rotate, causing the sliding threaded block 10 to move. Through the connecting rod 9, the outer support frame 7 and inner support frame 8 are pulled to move, causing the pallet base 2 to rise and fall, thereby lifting the bakelite packaging box off the ground and preventing it from getting damp.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, welding plate 6 is welded to pallet base 2, pulley 11 is rotatably connected to inner support frame 8, the top of inner support frame 8 can slide in slide rail 12 on welding plate 6 through pulley 11, the bottom of inner support frame 8 is rotatably connected to bottom frame 5, pulley 11 is rotatably connected to outer support frame 7, the bottom of outer support frame 7 slides in slide rail 12 inside bottom frame 5 through pulley 11, the top of outer support frame 7 is rotatably connected to bottom of pallet base 2, connecting rod 9 is rotatably connected to inner support frame 8 and outer support frame 7 respectively, sliding screw The pattern block 10 and the fixing block 15 are respectively welded to the connecting rod 9. The fixing block 15 is welded to the pallet base 2. The lead screw 13 is threadedly connected to the sliding threaded block 10. The lead screw 13 is rotatably connected to the fixing block 15. The lead screw 13 can rotate within the fixing block 15. The crank handle 14 is welded to the lead screw 13. The grip 4 is welded to the crank handle 14. The grip 4 can drive the crank handle 14 and the lead screw 13 to rotate. The support foot 3 is welded to the bottom frame 5. The bottom frame 5 can provide support for the inner support frame 8, the outer support frame 7, and the pallet base 2.

[0026] Preferably, through the arrangement of the outer support frame 7, inner support frame 8, sliding threaded block 10, fixed block 9, pallet base 2, lead screw 13, crank handle 14, grip 4, connecting rod 9, pulley 11, slide rail 12, and welding plate 6, when the operator rotates the grip 4, the crank handle 14 drives the lead screw 13 to rotate within the fixed block 15. Since the sliding threaded block 10 is threadedly connected to the lead screw 13, the sliding threaded block 10 can move axially along the lead screw 13, thereby synchronously pulling the inner support frame 8 and the outer support frame 7 through the connecting rod 9. The top of the inner support frame 8 is connected to the slide rail 12 of the welding plate 6 via the pulley 11. The inner sliding mechanism rotates around the bottom frame 5, and the tops of the outer support frame 7 and the inner support frame 8 simultaneously push the pallet base 2 to rise. The bottom end slides within the slide rail 12 of the bottom frame 5 via pulley 11, forming a stable four-bar linkage lifting structure. This structure allows the bakelite packaging box to be lifted away from the ground along with the pallet base 2, effectively isolating it from ground moisture and improving its service life. The adjustment process is also labor-saving and reliable. The welded structure between the support foot 3 and the bottom frame 5 further strengthens the overall support stability, ensuring the synchronization of the outer support frame 7 and the inner support frame 8 during the lifting process and preventing the bakelite packaging box from tilting.

[0027] Preferably, when it is necessary to lower the pallet base 2, the operator rotates the handle 4 in the opposite direction, causing the rocker handle 14 to rotate the lead screw 13 in the opposite direction within the fixed block 15. At this time, the sliding threaded block 10 moves away from the fixed block 15 along the lead screw 13, and simultaneously pulls the inner support frame 8 and the outer support frame 7 through the connecting rod 9. With the synchronous folding of the inner and outer support frames 7 and 8, the pallet base 2 descends smoothly, eventually bringing the bakelite packaging box close to the ground. During the entire descent process, the cooperation between the pulley 11 and the slide rail 12 ensures the smoothness of the movement, while the support feet 3 and the base frame 5 always maintain stable support to prevent structural displacement. The folded base facilitates the transportation of the bakelite packaging box 1 and the removal of items inside the bakelite packaging box 1.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
