Abstract
Description
Technical Field
[0001] This invention relates to the field of packaging boxes, and more specifically to an edge-resistant packaging box. Background Technology
[0002] When packaging items in a box, two rigid sponge pads are used to wrap the items to prevent damage during transportation. However, with rigid sponge pads, the edge strength of the box is low during transportation. When the box is transported to the express sorting station for sorting and delivery, the edges of the box may be damaged during handling, which may squeeze the items inside the sponge pads and cause damage. Summary of the Invention
[0003] The purpose of this invention is to provide an edge-resistant packaging box.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] An edge-resistant packaging box is provided, comprising a box body, four side-resistant tubes, four transverse support tubes, and four longitudinal support tubes. The four side-resistant tubes are located on the four inner edges of the box body. The length of each transverse support tube is parallel to the transverse direction of the box body, and each longitudinal support tube is parallel to the longitudinal direction of the box body. The two ends of the transverse support tubes are respectively inserted into the inner edges of the two side-resistant tubes, and the two ends of the longitudinal support tubes are inserted into the inner edges of the two side-resistant tubes.
[0006] Furthermore, the four longitudinal support tubes are divided into two upper longitudinal support tubes and two lower longitudinal support tubes. The two ends of each lower longitudinal support tube and the two ends of each upper longitudinal support tube are inserted into the inner edges of the two side pressure-resistant tubes. Each upper longitudinal support tube includes a buffer connection mechanism, two first inserts and a first cardboard tube. The two first inserts are fixedly installed on the outer ends of the two first cardboard tubes respectively. The inner sides of the two first cardboard tubes are connected to the two ends of the buffer connection mechanism. The side pressure-resistant tubes are provided with upper slots for the first inserts to be inserted.
[0007] Furthermore, the buffer connection mechanism includes a guide post, an abutment spring, and two first guide blocks. The two first guide blocks are fixedly installed on the inner side of the two first cardboard tubes respectively. The two ends of the guide post are slidably connected to the two first guide blocks. Each guide post has a limit plate at both ends. The abutment spring is used to provide an elastic force to keep the two first guide blocks away from each other.
[0008] Furthermore, the buffer connection mechanism includes a stop block and two locking blocks. The two locking blocks are respectively fixedly installed at one end of the two first cardboard tubes. The two ends of the stop block are inserted into the two locking blocks. The two ends of the stop block are provided with locking strips. The locking blocks are provided with locking grooves that engage with the locking strips.
[0009] Furthermore, the transverse support tube includes a second cardboard tube and two pads. The two pads are fixedly installed at both ends of the second cardboard tube and inserted into the two side pressure-resistant tubes. The side pressure-resistant tubes have clearance notches for inserting the pads.
[0010] Furthermore, one side of the pad is fitted with the outer edge of the first insert block.
[0011] Furthermore, both the pad and the first guide block are made of plastic.
[0012] Furthermore, a first plastic insert is provided on one side of the pad, which is inserted into the second cardboard tube.
[0013] Furthermore, a second plastic insert is provided on one side of the first guide block, which is inserted into the first cardboard tube.
[0014] Furthermore, the lower longitudinal support tube includes a third cardboard tube and two second inserts. The two second inserts are fixedly installed at both ends of the third cardboard tube, and the side pressure-resistant tube has a lower slot for inserting the second inserts.
[0015] The beneficial effects of the present invention are as follows: The edge-resistant packaging box supports the edge of the packaging box through four side pressure-resistant tubes, four transverse support tubes and four longitudinal support tubes, which strengthens the edge strength of the packaging box. Furthermore, the structure between them is easy to disassemble, so that the rigid sponge pad can be inserted into it, which facilitates the installation of the rigid sponge pad.
[0016] Furthermore, during installation, the eight corners of the packaging box are equipped with first inserts and pads to increase the strength of the ends. Attached Figure Description

Detailed Implementation
[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0031] Example 1:
[0032] Reference Figures 1 to 3The illustrated edge-resistant packaging box includes a box body 1, four side-supporting tubes 3, four transverse support tubes 4, and four longitudinal support tubes. The four side-supporting tubes 3 are located on the four inner edges of the box body 1. The length of each transverse support tube 4 is parallel to the transverse direction of the box body 1, and each longitudinal support tube is parallel to the longitudinal direction of the box body 1. The two ends of each transverse support tube 4 are inserted into the inner edges of two side-supporting tubes 3, and the two ends of each longitudinal support tube are also inserted into the inner edges of two side-supporting tubes 3. The four side-supporting tubes 3 support the four inner perimeter walls of the box body 1. The two transverse support tubes 4 and two longitudinal support tubes located at the bottom of the box body 1 support the four bottom edges of the box body 1. The two transverse support tubes 4 and two longitudinal support tubes located at the top of the box body 1 support the four top edges of the box body 1. Through these supports, the edges of the packaging box are protected against pressure, preventing damage to the goods caused by edge bending.
[0033] It is conceivable that the four side pressure-resistant tubes 3, the four transverse support tubes 4, and the four longitudinal support tubes can be glued to the packaging box to form an integrated structure. However, the box structure is not as strong as the disassembly method mentioned above. Due to the disassembly method, rigid plastic parts are added at the joints to connect the two paper tubes to improve strength.
[0034] like Figure 4 and Figure 5 As shown, the four longitudinal support tubes are divided into two upper longitudinal support tubes and two lower longitudinal support tubes 5a. The two ends of each lower longitudinal support tube 5a and the two ends of each upper longitudinal support tube are inserted into the inner edges of the two side pressure-resistant tubes 3. Each upper longitudinal support tube includes a buffer connection mechanism, two first inserts 5b1 and a first cardboard tube 5b2. The two first inserts 5b1 are fixedly installed on the outer ends of the two first cardboard tubes 5b2 respectively. The inner sides of the two first cardboard tubes 5b2 are connected to the two ends of the buffer connection mechanism. The side pressure-resistant tube 3 has an upper slot 3a for the first inserts 5b1 to be inserted. When installing the items inside the packaging box, a rigid sponge pad 2 needs to be installed. In order to avoid the upper longitudinal support tube blocking the installation of the rigid sponge pad 2, the rigid sponge pad 2 is first installed inside the box body 1. Then, the first insert 5b1 is aligned with the upper slot 3a by the compression buffer connection mechanism. Then, the first insert 5b1 is pushed into the upper slot 3a by releasing the buffer connection mechanism, thus completing the installation of the upper longitudinal support tube and the side pressure-resistant tube 3.
[0035] When installing the rigid sponge pad 2, the inside is wrapped with a display screen or other non-compressible items. Therefore, it is impossible to install the rigid sponge pad 2 by squeezing it. Even if it can be squeezed, it is difficult to squeeze both sides of the rigid sponge pad 2 inward at the same time.
[0036] like Figure 6 and Figure 7As shown, the buffer connection mechanism includes a guide post 5b4, a contact spring 5b5, and two first guide blocks 5b3. The two first guide blocks 5b3 are respectively fixedly installed on the inner sides of the two first cardboard tubes 5b2. The two ends of the guide post 5b4 are slidably connected to the two first guide blocks 5b3. Each end of the guide post 5b4 is provided with a limit plate 5b6. The contact spring 5b5 is used to provide an elastic force to keep the two first guide blocks 5b3 away from each other. When the two first cardboard tubes 5b2 are compressed and brought closer together, the contact spring 5b5 will be compressed. Through the first guide blocks 5b3 and the guide post 5b4, the two first cardboard tubes 5b2 can remain connected and avoid separation. The guide post 5b4 can also be set in the shape of a square tube to prevent relative rotation between the two first cardboard tubes 5b2.
[0037] like Figure 9 As shown, the transverse support tube 4 includes a second cardboard tube 4b and two pads 4a. The two pads 4a are fixedly installed at both ends of the second cardboard tube 4b, and are inserted into the two side pressure-resistant tubes 3. The side pressure-resistant tubes 3 have clearance notches 3b for the pads 4a to be inserted. By inserting the pads 4a into the side pressure-resistant tubes 3, the second cardboard tube 4b is supported and limited.
[0038] One side of the pad 4a is attached to the outer edge of the first insert 5b1. The attachment of the first insert 5b1 and the pad 4a strengthens the tightness of the structure.
[0039] Both pad 4a and the first guide block 5b3 are made of plastic. The use of plastic reduces weight.
[0040] A first plastic insert is provided on one side of the pad 4a, which is inserted into the second cardboard tube 4b. The first plastic insert enhances the structural rigidity of the second cardboard tube 4b, and the pad 4a can be mounted on the first plastic insert, providing an installation platform for the pad 4a.
[0041] A second plastic insert is provided on one side of the first guide block 5b3, which is inserted into the first cardboard tube 5b2. The second plastic insert enhances the structural rigidity of the first cardboard tube 5b2, and the first guide block 5b3 can be mounted on the second plastic insert, providing an installation platform for the first guide block 5b3.
[0042] like Figure 9 and Figure 10As shown, the lower longitudinal support tube 5a includes a third cardboard tube 5a1 and two second inserts 5a2. The two second inserts 5a2 are respectively fixedly installed at both ends of the third cardboard tube 5a1. The side pressure-resistant tube 3 has a lower slot 3c for inserting the second inserts 5a2. Through the lower slot 3c and the second inserts 5a2, a snap-fit connection can be formed between the lower longitudinal support tube 5a and the side pressure-resistant tube 3.
[0043] Example 2:
[0044] The difference from Example 1 is that, as Figure 8 As shown, the buffer connection mechanism includes a stop block 5b8 and two locking blocks 5b7. The two locking blocks 5b7 are respectively fixedly installed at one end of the two first cardboard tubes 5b2. The two ends of the stop block 5b8 are inserted into the two locking blocks 5b7. The two ends of the stop block 5b8 are provided with locking strips 5b9. The locking blocks 5b7 are provided with locking grooves that engage with the locking strips 5b9. By setting the stop block 5b8, it can be pulled out from the first cardboard tube 5b2. When the two first insert blocks 5b1 are inserted, it is not necessary to squeeze the first cardboard tube 5b2, thus avoiding damage to the first cardboard tube 5b2 due to squeezing.
[0045] This edge-resistant packaging box uses four side pressure-resistant tubes, four transverse support tubes, and four longitudinal support tubes to support the edges of the packaging box, thereby strengthening the edge strength. It also adopts an easily disassembled structure, which allows the rigid sponge pad to be inserted into it, making it easy to install the rigid sponge pad. During installation, the eight corners of the packaging box are equipped with first insert blocks and pads to increase the strength of the ends.
[0046] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
