[0023] 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. Example

[0024] like Figures 1 to 6 As shown, this utility model discloses a packaging box body. The technical solution adopted includes two first square tubes 1 arranged in parallel. The two first square tubes 1 are connected by two connecting square tubes 10. The first square tubes 1 and the connecting square tubes 10 form a rectangular bottom frame, and a bottom plate is welded on the bottom frame. Both ends of the two first square tubes 1 are welded with end square tubes 2. In order to supplement the side support strength, two supporting square tubes 4 are also welded on each first square tube 1. The two supporting square tubes 4 are located between the two end square tubes 2. A second square tube 5 is welded between the end square tube 2 and the adjacent supporting square tube 4. A third square tube 6 is welded between the two supporting square tubes 4 on the same side. Side plates 7 are welded on the side frame formed by the first square tube 1, end square tube 2, supporting square tube 4, second square tube 5, and third square tube 6. In order to facilitate the positioning of the cover plate 13, the top surfaces of the end square tubes 2 and the supporting square tubes 4 are higher than the top surfaces of the second square tubes 5 and the third square tube 6.

[0025] To facilitate the expansion of the housing, two expansion holes 201 are provided on the vertical surface of the end square tube 2. The two upper expansion holes 201 on the same side end square tube 2 are coaxial, and the two lower expansion holes 201 are coaxial, and are equipped with connecting bolts 9 that match the size of the expansion holes 201. Pin holes 501 are provided on the opposite surfaces of the two end square tubes 2 and the opposite surfaces of the two second square tubes 5.

[0026] Also includes end cap 8, such as Figure 4As shown, the end cap 8 includes a frame 801, which is a square frame. An end plate 802 is welded inside the frame 801. To facilitate the disassembly of the end cap 8, a guide plate 803 is provided on the inner top surface of the frame 801. A first through hole is opened on the guide plate 803, and a second through hole is opened on the frame 801 that corresponds to the position of the first through hole and matches its size. The first through hole and the second through hole are coaxial. A pin 11 slides in contact with the first through hole and the second through hole. The pin 11 has a T-shaped structure, including a horizontal pin body and a vertical handle. The pin body slides in contact with the first through hole and the second through hole. The first and second through holes correspond to the pin hole 501. Inserting the pin 11 through the first and second through holes into the pin hole 501 connects the end cap 8 to the frame. Pulling the pin 11 out of the pin hole 501 allows for quick disassembly of the end cap 8. To maintain the position of the pin 11 when connecting or disassembling the end cap 8, a partition 804 is provided on the end plate 802. The two ends of the partition 804 form a locking position with the frame 801 and the directional plate 803, respectively. The handle of the pin 11 can be placed in either the locking or unlocking position. Since the bottom surface of the end cap 8 is in surface contact with the base plate and the connecting square tube 10, inserting the pin 11 into the pin hole 501 ensures stable installation of the end cap 8. To further improve the stability of the end cap 8 on the connecting square tube 10, a through bottom hole 805 is opened at the bottom of the frame 801, and a positioning hole corresponding to the position and matching the size of the bottom hole 805 is opened on the connecting square tube 10. A pin 12 is inserted through the bottom hole 805 into the positioning hole for secondary positioning.

[0027] It also includes a cover plate 13, which is a square plate with corner grooves 1301 at its four corners. The corner grooves 1301 are matched in size with the end square tubes 2 and the supporting square tubes 4. To reduce the manufacturing cost of the cover plate 13, the cross-sectional dimensions of the end square tubes 2 and the supporting square tubes 4 are controlled to be the same, and the two supporting square tubes 4 are controlled to be located at the trisection points between the two end square tubes 2 on the same side. Therefore, when processing the cover plate 13, the rectangular area enclosed by the end square tubes 2 on both sides and the two adjacent supporting square tubes 4 can be used as a unit, and the cover plate 13 can be processed according to the size of this unit. Figure 5 , Figure 6 As shown.

[0028] To facilitate quick placement of the lifting connectors under the packaging box during transport, feet 3 are installed on the bottom of the frame. To prevent slippage of the lifting straps during transport, anti-slip components 14 are installed on both sides of the feet 3.

[0029] To reduce the impact of vibrations during transportation on the product, U-shaped cushioning cotton was laid inside the packaging box as a buffer. To improve the strength of the packaging box, the first square tube 1, the end square tube 2, the supporting square tube 4, the second square tube 5, the third square tube 6, and the frame 801 are all made of iron, while the side plate 7, the bottom plate, and the end plate 802 are all made of iron plate.

[0030] The working principle of this utility model:

[0031] If the current box length meets the product packaging requirements, place the product on the cushioning cotton inside the box, and lay the cover plate 13 on the top surface of the box. When laying, make the corner groove 1301 of the cover plate 13 abut against the vertical surface of the end square tube 2 and / or the supporting square tube 4, and put the lifting equipment's sling between the foot 3 and the anti-detachment part 14 for lifting and transportation.

[0032] If the current box is too short, remove the box end cap 8. During removal, pull the handle of the pin 11 from the locked position and pull the pin 11 towards the centerline of the end cap 8 to disengage the pin 11 from the pin hole 501. After the handle of the pin 11 engages with the guide plate 803, screw the handle into the unlocked position. If pin 12 is installed, pull out pin 12, remove the end cap 8, and connect an appropriate number of boxes. When connecting, align the end faces of the two boxes, with the end square tubes 2 of the two boxes facing each other. Connect the two end square tubes 2 by passing the connecting bolts 9 through the expansion holes 201 and tightening them with nuts. After the connection is complete, place the product on the cushioning cotton of the box and reinstall the end cap 8 at the appropriate pin hole 501. During installation, pull the handle of the pin 11 out of the unlocked position and slide the pin 11 so that the pin body enters the pin hole 501. If the end cap 8 is on the top surface of the connecting square tube 10 at this time, insert the pin 12 through the bottom hole 805 into the positioning hole. After laying the cover plate 13, transport the product.

[0033] Upon arrival at the destination, open cover 13, remove the product, and recycle the packaging box.
