Description
Technical Field
[0001] The invention relates to the technical field of packaging boxes, in particular to a multifunctional packaging box. Background Art
[0002] E-commerce logistics is a complete set of electronic logistics solutions, which is commonly known as the ERP system. Judging from the relevant operations shown in the current e-commerce logistics, logistics still requires machines and people to move, but this is conducive to the real-time allocation of goods from all over the country and effective classification. Therefore, e-commerce logistics must start with traditional logistics. Although various logistics distribution at home and abroad have mostly surpassed the stage of simple door-to-door delivery, they are still traditional logistics distribution at the level. Therefore, there are various drawbacks and problems in the operation that traditional logistics distribution cannot overcome. It does not yet have or basically does not have the characteristics of new logistics distribution that is information-based, modernized, and socialized. With the rapid rise of e-commerce logistics, the transportation and allocation of goods are developing in the direction of intelligence, and the goods need to be packaged as a whole in the packaging to be delivered to customers.
[0003] The current packaging boxes have certain shortcomings:
[0004] 1. When transporting bottled objects in packaging boxes, bubble film is usually wrapped on the outside of the bottled objects. However, in actual transportation, the packages will be thrown around at will, causing the bottled objects to shake inside the packaging box, increasing the possibility of the bottled objects breaking and causing economic losses to customers.
[0005] 2. At the same time, when packaging and transporting parcels of different sizes, if the objects and the objects in the packaging box are not matched enough, the objects will shake inside the packaging box. During the transportation process, the objects will undergo multiple transfers and sorting, which will increase the degree of damage to the objects. When there are a large number of objects in the same batch, multiple packaging boxes are required for packaging. They are all wrapped separately in one packaging box. Therefore, multiple packaging boxes of a batch of objects will be missed during transportation, causing the loss of packages.
[0006] 3. When transporting fresh fruits, general boxes are opened with holes inside to improve the ventilation efficiency of the fresh fruits inside. However, the perforated boxes will greatly damage their strength, and the fresh fruits cannot be fixed inside the boxes, resulting in frequent breakage and damage. Summary of the invention

[0040] As a preferred solution of this embodiment: a buffer groove is provided at one end of the connecting seat 9 close to the pushing plate 10, and the clamping strip 11 slides inside the buffer groove so that the clamping strip 11 can move.
[0041] As a preferred solution of this embodiment: the first rack 7 is located inside the rack groove 401, and the first rack 7 and the second rack 403 are meshed with each other, so that the movable plate 301 can be fixed at any height.
[0042] Embodiment 1, as Figure 7-8 As shown, when the rotating shaft 506 is rotated, the rotating shaft 506 needs to be released. At this time, the rotating plate 503 drives the two sets of driving rods 504 to slide inside the driving groove 509. Since the driving rod 504 is performing a circular motion, while sliding longitudinally inside the driving groove 509, the two sets of driving rods 504 push the two sets of third racks 508 to move laterally away from each other through the driving groove 509, so that the two sets of third racks 508 and the gear 502 are separated from each other and released from the meshing state. At this time, the rotating shaft 506 can be rotated to drive the two sets of ejector rods 507 to rotate, and the two sets of wedge blocks 307 are pushed away from each other to realize the movement of the arc extrusion plate 303 and fix the bottle body. Then the rotating plate 503 is released. Under the elastic force of the two sets of first springs 505, the third rack 508 is reset and meshed with the gear 502 to fix the rotating shaft 506.
[0043] Embodiment 2, as Figure 1 and Figure 3As shown, when the breathable component 2 is used, when the air pump 205 is working in the forward direction, the interior of the second air inlet chamber 206 can be inflated through the second one-way valve 210, and the function of the second one-way valve 210 is only to allow the internal gas of the installation bin 209 to enter the interior of the second air inlet chamber 206, and to inflate the interior of the airbag 207, so that the airbag 207 expands and gradually contacts and squeezes the upper surface of the object to fix it, and when the air pump 205 is reversed, the interior of the first air inlet chamber 202 can be evacuated through the first one-way valve 203, and the function of the first one-way valve 203 is only to allow the gas of the first air inlet chamber 202 to enter the interior of the installation bin 209, and the interior of the packaging box body 1 can be evacuated through the three sets of ventilation pipes 208, and the internal air of the packaging box body 1 can flow, ensuring that the internal air of the packaging box body 1 flows relatively dryly, and ensuring the freshness of fruits and vegetables and not being spoiled.
[0044] Working principle: When the bottle-shaped object is to be transported or wrapped, the movable plate 301 needs to be unfolded, and at this time, the push rod 404 is pushed to slide inside the through groove 406, driving the second rack 403 and the first rack 7 to move away from each other in contact and meshing state. At this time, when the movable plate 301 is pulled upward to a certain height, the two sets of push rods 404 are released, and under the magnetic force of the magnet 402, the second rack 403 is attracted, so that the second rack 403 is reset and re-engaged with the first rack 7, and the movable plate 301 is fixed at a suitable height. At this time, the bottle body is inserted into the inside of the placement hole 304, and the rotating shaft 506 is rotated to drive the two sets of push rods 507 to rotate, so that the two sets of push rods 507 push the two sets of wedge blocks 307 away from each other, drive the two sets of transmission rods 306 away from each other, and drive the arc-shaped extrusion plate 303 to squeeze the bottle body and fix it inside the placement hole 304 through multiple sets of extrusion rods 302.
[0045] When the two groups of packaging box bodies 1 are fixedly connected, the two groups of connecting plates 6 are inserted between the two groups of connecting seats 9 so that one side of the two groups of connecting plates 6 contacts the oblique sides of the card strips 11. When moving, the connecting plates 6 push the two groups of card strips 11 to move toward the inside of the buffer groove, and squeeze the pull rod 14, so that the card strips 11 slide on the outside of the connecting plates 6. When the connecting plates 6 drive the card slots 15 to move to the card strips 11, the card strips 11 are bounced into the inside of the card slots 15 under the elastic force of the pull rod 14, and the connecting plates 6 and the connecting seats 9 are fixed to each other, thereby fixing the two groups of packaging box bodies 1. At the same time, the pushing plates 10 on the two groups of packaging box bodies 1 contact each other and push the spring telescopic rod 12 to move, driving the two groups of clamping plates 8 to contact and squeeze the surface of the object, so that the object can be fixedly clamped.
[0046] At the same time, when the breathable component 2 is used, when the air pump 205 is working forward, the interior of the second air inlet chamber 206 can be inflated through the second one-way valve 210, and the interior of the airbag 207 can be inflated, so that the airbag 207 expands and gradually contacts and squeezes the upper surface of the object to fix it. When the air pump 205 is reversed, the interior of the first air inlet chamber 202 can be evacuated through the first one-way valve 203, and the interior of the packaging box body 1 can be evacuated through the three sets of ventilation pipes 208. The internal air of the packaging box body 1 can flow, ensuring that the internal air of the packaging box body 1 flows relatively dry, and ensuring the freshness of the fruits and vegetables without being spoiled.
[0047] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
