[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Please see Figures 1-7 The present invention provides the following technical solution:
[0027] A deformation-resistant cardboard box structure includes: a box body 1, multiple L-shaped protective strips 2 uniformly fixedly connected at the corners of the outer wall of the box body 1, a base 3 fixedly connected to the bottom of the outer wall of the box body 1, the upper surface of the base 3 fixedly connected to the lower end face of the L-shaped protective strips 2, a first rectangular partition 4 fixedly installed on the outer wall of the box body 1 and fixedly connected to the upper end face of the base 3, two first reinforcing strips 5 and two second reinforcing strips 6 uniformly and movably connected to the upper surface of the first rectangular partition 4, the two first reinforcing strips 5 and the two second reinforcing strips 6 being arranged opposite each other, the first reinforcing strips 5 and the second reinforcing strips 6 being arranged adjacent to each other, two sets of snap-fit components 7 symmetrically arranged in pairs, each set of snap-fit components 7 being correspondingly installed inside each second reinforcing strip 6, the bottom of the snap-fit component 7 being snapped into the inside of the first reinforcing strip 5, a spring 8 elastically connected to one side of the snap-fit component 7, the end of the spring 8 away from the snap-fit component 7 being elastically connected to the inner wall of the second reinforcing strip 6.
[0028] The anti-deformation carton structure uses multiple L-shaped protective strips 2 to protect multiple corners of the carton body 1 and strengthen the structural strength of the corners. The base 3 strengthens the bottom structure of the carton body 1, and the base 3 is fixedly connected to the lower end face of the L-shaped protective strips 2, thereby enhancing the integrity between the base 3 and the L-shaped protective strips 2 and further improving the structural strength of this application to prevent the carton body 1 from deforming. A first rectangular baffle 4 is fixedly installed on the upper end face of the multiple L-shaped protective strips 2, and the top structure of the carton body 1 is strengthened by the first rectangular baffle 4.
[0029] Furthermore, the first rectangular enclosure 4 restricts the installation positions of the two first reinforcing strips 5 and the two second reinforcing strips 6. The two first reinforcing strips 5 are located at the two width sections of the box body 1, and the two second reinforcing strips 6 are located at the two length sections of the box body 1. After the personnel have placed the items and closed the box, the first reinforcing strips 5 can be bent and placed on the upper surface of the box body 1, and then the second reinforcing strips 6 can be bent so that both ends of the second reinforcing strips 6 cover the upper surfaces of the two first reinforcing strips 5. Each end of the second reinforcing strip 6 is equipped with a snap-fit assembly 7, so that when the second reinforcing strip 6 is placed on the upper surface of the first reinforcing strip 5, the snap-fit assembly 7 is restricted by the elastic force of the spring 8. The position of component 7 allows the bottom of the snap-fit component 7 to snap into the interior of the first reinforcing strip 5, thereby limiting the usable position between the second reinforcing strip 6 and the first reinforcing strip 5. This further strengthens the structural strength of the top of the box 1 and improves the anti-deformation effect of the box 1. The anti-deformation reinforcement structure of the carton provided in this application is located on the outside of the box 1. This can improve the structural strength of the carton while minimizing the impact on the placement of items due to the reinforcement structure occupying the internal space of the box 1. At the same time, it can also minimize the damage caused by items colliding with the reinforcement structure during transportation, making this application more practical.
[0030] The base 3 includes a rectangular frame plate 301 fixedly connected to the lower surface of the box body 1. A second rectangular enclosure plate 302 is fixedly connected to the outer wall of the rectangular frame plate 301. The inner wall of the second rectangular enclosure plate 302 is fixedly connected to the outer wall of the box body 1. The upper surface of the second rectangular enclosure plate 302 is fixedly connected to the lower end face of the L-shaped guard strip 2.
[0031] Specifically, the rectangular frame plate 301 is fixedly installed on the lower surface of the box body 1, and the second rectangular enclosure plate 302 is fixedly installed on the outer wall of the box body 1, thereby enhancing the structural strength at the bottom corners of the box body 1 and preventing the box body 1 from deforming during use.
[0032] The first reinforcing strip 5 includes a first rectangular strip 501 movably connected to the upper surface of the first rectangular enclosure 4. The upper surface of the first rectangular strip 501 is uniformly provided with snap-fit grooves 502. The bottom of the snap-fit component 7 is located inside the snap-fit grooves 502, and the two are snapped together.
[0033] Specifically, after the first rectangular strip 501 is bent from the connection point with the first rectangular panel 4, it can cover the upper surface of the box 1, thereby protecting the corners of the top of the box 1. The snap-fit groove 502 can limit the snap-fit position between the snap-fit component 7 and the first reinforcing strip 5.
[0034] The second reinforcing strip 6 includes a second rectangular strip 601 movably connected to the upper surface of the first rectangular panel 4. The upper surface of the second rectangular strip 601 is uniformly provided with mounting grooves 602, and the lower surface of the second rectangular strip 601 is uniformly provided with openings 603 that communicate with the mounting grooves 602. The snap-fit component 7 is located inside the mounting grooves 602 and the openings 603.
[0035] Specifically, after the second rectangular strip 601 is bent from the connection point with the first rectangular panel 4, it can cover the bent first rectangular strip 501, thereby protecting the corners of the top of the box 1. At the same time, it can also allow the bottom of the snap-fit assembly 7 installed inside the mounting slide 602 and the through 603 to snap into the snap-fit groove 502.
[0036] The snap-fit assembly 7 includes a rectangular block 701 located inside the mounting slide 602. A snap hook 702 is fixedly connected to the lower surface of the rectangular block 701. The bottom of the snap hook 702 passes through the inside of the through-hole 603 and snaps into the inside of the snap-fit groove 502.
[0037] Specifically, the rectangular block 701 restricts the installation position of the hook 702. One side of the rectangular block 701 is elastically connected to one end of the spring 8, so that when there is no external force, the position of the rectangular block 701 can be restricted by the elastic force of the spring 8, so that the hook 702 installed on the lower surface of the rectangular block 701 can maintain the engagement state with the engagement groove 502. When the operator moves the rectangular block 701 toward the spring 8, it can compress the spring 8 to retract, and at the same time adjust the engagement part of the hook 702 and the engagement groove 502 to separate, so that the operator can easily open the bent second reinforcing strip 6 and the first reinforcing strip 5 to take out the items inside the box 1.
[0038] To prevent slippage when personnel move the rectangular block 701, an anti-slip pad 9 is fixedly connected to the upper surface of the rectangular block 701.
[0039] In order to guide the movement of the rectangular block 701 and improve the stability of the rectangular block 701 during movement, guide strips 11 are fixedly connected to both sides of the inner wall of the mounting groove 602, and limit grooves 12 are opened on both sides of the rectangular block 701, with each guide strip 11 located inside each limit groove 12.
[0040] In order to further increase the friction between the person and the hand when the rectangular block 701 is moved, anti-slip strips 10 are uniformly fixedly connected to the upper surface of the anti-slip mat 9.

Fix the first rectangular side plate 4 to the top outer wall of the carton body 1 and fix it to the upper end face of the L-shaped guardrails 2. The first rectangular side plate 4 is used to reinforce the top of the carton body 1 and to define the installation position of the first reinforcing strip 5 and the second reinforcing strip 6.
[0043] Step 2, sealing the carton: Place the items inside the carton 1 as needed, bend the two first reinforcing strips 5 from the first rectangular panel 4 and cover the upper surface of the carton 1, then bend the two second reinforcing strips 6 and cover the folded first reinforcing strips 5.
[0044] Step 3: Sealing and reinforcement: The bottom of the snap-fit component 7, which is set inside the second reinforcing strip 6, is snapped into the snap-fit groove 502 of the first reinforcing strip 5, and the snap-fit component 7 is secured by the spring 8 to form a stable closed structure and improve the anti-deformation effect of the box 1.
[0045] Step 4: Unlocking the lid: Push the rectangular block 701 along the limiting slide 12 towards the spring 8 by hand, compress the spring 8, and make the hook 702 disengage from the locking groove 502, thereby unlocking the second reinforcing strip 6. Lift the second reinforcing strip 6 and the first reinforcing strip 5 in sequence to open the lid of the box 1 and take out the items.
[0046] Through the operations of process one, process two, process three, and process four, the structure used to reinforce the cardboard box can be installed on the outside of the box body 1. While improving the structural strength of the cardboard box, it can also minimize the impact on the placement of items due to the reinforcement structure occupying the internal space of the box body 1. At the same time, it can also prevent items from being damaged by colliding with the reinforcement structure.
