Description

Technical Field

[0001] This utility model relates to the field of turnover box technology, specifically a folding turnover box. Background Technology

[0002] Foldable turnover boxes are standardized logistics containers widely used in factory production, logistics transportation, and express delivery. Their core feature is their foldable design: when in use, they unfold to form a stable box structure to carry various goods; when not in use, they fold into a flat shape, significantly reducing the space occupied by empty boxes during recycling, transportation, and warehousing. This design is particularly suitable for high-volume, high-batch logistics scenarios, such as the turnover of raw materials and finished products in industries like automotive parts, electronics, and fresh food.

[0003] In practical use, the existing folding turnover boxes mainly use a snap-fit ​​structure to connect the short side panels and the long side panels, which is not very stable. They are prone to loosening during loading or handling, affecting the overall load-bearing capacity of the box. On the other hand, the connection between the long and short side panels and the base lacks effective multiple restraints, which makes the box prone to shaking when subjected to external impacts or vibrations after it is unfolded, reducing the reliability and service life of the turnover box. Therefore, we propose a folding turnover box. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a folding turnover box. A fixing component is provided between adjacent short side panels and long side panels to achieve connection and fixation between adjacent short side panels and long side panels. The long side panel achieves a stable connection with the base through a double limiting structure of "limiting plate one abutting against the top side of the baffle" and "limiting block one inserting into limiting groove one". The short side panel enhances the stability of the connection with the base through a limiting structure of "limiting block two inserting into limiting groove two", thus solving the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a folding turnover box, comprising a base, short side plates on the left and right sides of the top of the base, and long side plates on the front and back sides of the top of the base. The base, the two sets of short side plates, and the two sets of long side plates together form a box with an open top. Several hinge slots are provided on the left and right sides of the top of the base. Baffles are fixedly connected to the front and back sides of the top of the base. Several hinge slots are provided on the top of the two sets of baffles. The bottom of the short side plates is fixed... A plurality of hinge rods 1 are fixedly connected, and a plurality of hinge rods 2 are fixedly connected to the bottom of the long side plate. The hinge rods 1 and 2 are respectively rotatably disposed inside the hinge grooves 1 and 2. Limiting plates 3 are fixedly connected to the left and right sides of the interior of the hinge groove 1, and limiting plates 4 are fixedly connected to the front and rear sides of the interior of the hinge groove 2. The top side of the hinge rod 1 abuts against the bottom side of the limiting plate 3, and the top side of the hinge rod 2 abuts against the bottom side of the limiting plate 4. A fixing component is provided between the adjacent short side plate and long side plate.

[0006] Preferably, the fixing assembly includes a mounting groove, a first mounting plate, and a second mounting plate. The mounting groove is formed on the outer surface of the short side plate. The first mounting plate and the second mounting plate are fixedly connected between the upper and lower sides inside the mounting groove. A sliding plate is slidably inserted between the first mounting plate and the second mounting plate. A second limiting plate is fixedly connected above and below the side of the first mounting plate near the second mounting plate. An elastic plate is fixedly connected to the upper and lower sides of the sliding plate. The outer surfaces of the two sets of elastic plates abut against the outer surfaces of the two sets of second limiting plates, respectively. A fixing block is fixedly connected to the end of the sliding plate near the long side plate. The fixing block slides out of the outer side of the short side plate. A fixing groove is formed on the side of the long side plate near the short side plate. The fixing block is slidably inserted into the fixing groove. A pull ring is fixedly connected to the end of the sliding plate away from the long side plate.

[0007] Preferably, slots are provided on both the front and rear sides of the short side plate, and insert plates are fixedly connected to both the left and right sides of the long side plate, with the insert plates inserted into the slots.

[0008] Preferably, a plurality of limiting plates are fixedly connected to the bottom of the two sets of long side plates on the side away from each other. The bottom side of the limiting plate abuts against the top side of the baffle. Limiting blocks are fixedly connected to the top left and right sides of the baffle. Two sets of limiting grooves are opened at the bottom of the two sets of long side plates on the side away from each other. The limiting blocks are inserted into the limiting grooves.

[0012] This invention provides a foldable turnover box. Compared with the prior art, it has the following advantages:

[0013] 1. This type of folding turnover box has a fixing component between adjacent short side panels and long side panels. The sliding plate of the fixing component generates continuous elastic force through the abutment of the elastic plate and the second limiting plate, so that the fixing block is stably inserted into the fixing groove of the long side panel, forming an elastic self-tightening fixing, which can effectively counteract the loosening caused by vibration. At the same time, the insert plate of the long side panel is inserted into the slot of the short side panel to form a "mortise and tenon" corner connection, which further enhances the deformation resistance of the connection between the short side panel and the long side panel.

[0014] 2. This type of folding turnover box has a double limiting structure in which the long side plate is stably connected to the base through "limiting plate one abutting against the top side of the baffle" and "limiting block one being inserted into limiting groove one"; the short side plate has a limiting structure in which "limiting block two is inserted into limiting groove two" to enhance the stability of the connection with the base, thereby achieving three-dimensional reinforcement, effectively limiting the displacement of the long and short side plates, and avoiding shaking of the box caused by external forces during loading and transportation.

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a folding turnover box, including a base 1, short side plates 2 are provided on the left and right sides of the top of the base 1, and long side plates 3 are provided on the front and back sides of the top of the base 1. The base 1, the two sets of short side plates 2, and the two sets of long side plates 3 together form a box body with an open top. Several hinge slots 24 are provided on the left and right sides of the top of the base 1. Baffles 6 are fixedly connected to the front and back sides of the top of the base 1. Several hinge slots 25 are provided on the top of the two sets of baffles 6. Several hinge rods 13 are fixedly connected to the bottom of the short side plates 2. Several hinge rods 28 are fixedly connected to the bottom of the long side plate 3. Hinges 13 and 28 are respectively rotatably arranged inside hinge slots 1 and 25. Limiting plates 3 26 are fixedly connected to the left and right sides of the interior of hinge slot 1, and limiting plates 4 27 are fixedly connected to the front and rear sides of the interior of hinge slot 25. The top side of hinge rod 13 abuts against the bottom side of limiting plate 3 26, and the top side of hinge rod 28 abuts against the bottom side of limiting plate 4 27. A fixing component is provided between the adjacent short side plate 2 and long side plate 3.

[0024] When the folding turnover box is in operation, to unfold the box, rotate the short side plate 2 and the long side plate 3. The hinge rod 13 at the bottom of the short side plate 2 rotates within the hinge groove 24 at the top of the base 1, and the hinge rod 28 at the bottom of the long side plate 3 rotates within the hinge groove 25 at the top of the baffle 6. As it rotates, the top side of the hinge rod 13 abuts against the bottom side of the limiting plate 26 in the hinge groove 24, and the top side of the hinge rod 28 abuts against the bottom side of the limiting plate 27 in the hinge groove 25. At this time, the short side plate... Both the short side plate 2 and the long side plate 3 remain perpendicular to the base 1. They are then fixed together by the fixing components between the short side plate 2 and the long side plate 3, so that the base 1, the two sets of short side plates 2 and the two sets of long side plates 3 together form a box with an open upper side. When folding is required, the fixing components are released from the short side plate 2 and the long side plate 3. The short side plate 2 and the long side plate 3 are rotated in the opposite direction, so that the hinge rod 13 rotates in the hinge groove 24 and the hinge rod 28 rotates in the hinge groove 25 in the opposite direction until the folding operation is completed.

[0025] The fixing assembly includes a mounting groove 15, a mounting plate 16, and a mounting plate 17. The mounting groove 15 is formed on the outer surface of the short side plate 2. The mounting plate 16 and the mounting plate 17 are fixedly connected between the upper and lower sides inside the mounting groove 15. A sliding plate 18 is slidably inserted between the mounting plate 16 and the mounting plate 17. The upper and lower sides of the mounting plate 16 near the mounting plate 17 are fixedly connected to the limiting plate 19. The upper and lower sides of the sliding plate 18 are fixedly connected to the elastic plate 20. The outer surfaces of the two sets of elastic plates 20 abut against the outer surfaces of the two sets of limiting plates 19 respectively. A fixing block 22 is fixedly connected to the end of the sliding plate 18 near the long side plate 3. The fixing block 22 slides out of the outside of the short side plate 2. A fixing groove 23 is formed on the side of the long side plate 3 near the short side plate 2. The fixing block 22 is slidably inserted into the fixing groove 23. A pull ring 21 is fixedly connected to the end of the sliding plate 18 away from the long side plate 3.

[0026] When the fixing assembly is working, since the mounting groove 15 is opened on the outer surface of the short side plate 2, the mounting plate 16 and the mounting plate 17 are fixed between the upper and lower sides inside the mounting groove 15. The sliding plate 18 slides between the mounting plate 16 and the mounting plate 17. The mounting plate 16 is provided with a limiting plate 19 on the upper and lower sides of the side close to the mounting plate 17. The outer surface of the elastic plate 20 on the upper and lower sides of the sliding plate 18 abuts against the outer surface of the limiting plate 19, so that the sliding plate 18 has an elastic force in the direction of the long side plate 3. The fixing block 22 at the end of the sliding plate 18 close to the long side plate 3 slides out of the outside of the short side plate 2 under the action of the elastic force and is inserted into the fixing groove 23 of the long side plate 3, thereby fixing the short side plate 2 and the long side plate 3. Pulling the pull ring 21 at the other end of the sliding plate 18 can drive the fixing block 22 to disengage from the fixing groove 23 and release the fixation.

[0027] Slots 12 are provided on both the front and rear sides of the short side plate 2, and insert plates 11 are fixedly connected to both the left and right sides of the long side plate 3. The insert plates 11 are inserted into the slots 12. When the short side plate 2 and the long side plate 3 are erected and in an enclosed state, the insert plates 11 of the long side plate 3 are correspondingly inserted into the slots 12 of the short side plate 2. Through the cooperation of the insert plates 11 and the slots 12, an auxiliary fixation is formed at the connection between the short side plate 2 and the long side plate 3, which enhances the stability of the connection between the two.

[0028] Several limiting plates 5 are fixedly connected to the bottom of the two sets of long side plates 3 on the side away from each other. The bottom side of the limiting plate 5 abuts against the top side of the baffle 6. Limiting blocks 7 are fixedly connected to the top left and right sides of the baffle 6. Two sets of limiting grooves 8 are opened at the bottom of the two sets of long side plates 3 on the side away from each other. The limiting blocks 7 are inserted into the limiting grooves 8. When the long side plate 3 is upright, the bottom side of the limiting plate 5 abuts against the top side of the baffle 6, providing vertical support and limiting for the long side plate 3. At the same time, the limiting blocks 7 on the baffle 6 are inserted into the limiting grooves 8 of the long side plate 3, limiting the long side plate 3 in the horizontal direction and preventing the long side plate 3 from shaking.

[0029] Limiting blocks 10 are fixedly connected to the bottom center of both short side plates 2. Limiting grooves 14 are opened on the top left and right sides of the base 1. The limiting blocks 10 are inserted into the limiting grooves 14. When the short side plates 2 are erected, the limiting blocks 10 at the bottom of the short side plates 2 are inserted into the limiting grooves 14 of the base 1. Through the cooperation of the limiting blocks 10 and the limiting grooves 14, the connection between the short side plates 2 and the base 1 is positioned and limited, thereby enhancing the stability of the short side plates 2.

[0030] Both sets of short side plates 2 have a pull groove 4 on the side that is far apart from each other. When it is necessary to rotate the short side plate 2 to fold or unfold, the operator can put his / her hand into the pull groove 4 and pull or push the pull groove 4 to more conveniently drive the short side plate 2 to rotate around the hinge point, thus improving the convenience of operation.

[0031] Several reinforcing ribs 9 are fixedly connected to the sides of the two sets of long side plates 3 that are far apart from each other. The reinforcing ribs 9 increase the structural strength of the surface of the long side plate 3, improve the deformation resistance of the long side plate 3, and make the long side plate 3 less prone to bending or damage when subjected to cargo pressure or external collision, thus extending the service life of the long side plate 3.

[0032] Working principle: When the folding turnover box needs to be unfolded, the short side plate 2 and the long side plate 3 are rotated. The hinge rod 13 at the bottom of the short side plate 2 rotates within the hinge groove 24 at the top of the base 1, and the hinge rod 28 at the bottom of the long side plate 3 rotates within the hinge groove 25 at the top of the baffle 6. As they rotate, the top side of the hinge rod 13 abuts against the bottom side of the limiting plate 26 in the hinge groove 24, and the top side of the hinge rod 28 abuts against the bottom side of the limiting plate 27 in the hinge groove 25. At this time, both the short side plate 2 and the long side plate 3 remain perpendicular to the base 1. Since the mounting groove 15 is opened on the outer surface of the short side plate 2, the mounting plate 16 and the mounting plate 27 are fixed. The sliding plate 18 is fixed between the upper and lower sides inside the mounting groove 15. It slides between the mounting plate 16 and the mounting plate 17. The mounting plate 16 is provided with a limiting plate 29 on the upper and lower sides of the side close to the mounting plate 17. The outer surface of the elastic plate 20 on the upper and lower sides of the sliding plate 18 abuts against the outer surface of the limiting plate 29, so that the sliding plate 18 has an elastic force in the direction of the long side plate 3. The fixing block 22 at the end of the sliding plate 18 close to the long side plate 3 slides out of the outside of the short side plate 2 under the action of the elastic force and is inserted into the fixing groove 23 of the long side plate 3, so as to fix the short side plate 2 and the long side plate 3, so that the base 1, the two sets of short side plates 2 and the two sets of long side plates 3 together form a box with an open upper side.

[0033] When the short side plate 2 and the long side plate 3 are erected and in an enclosed state, the insert plate 11 of the long side plate 3 is inserted into the slot 12 of the short side plate 2. Through the cooperation of the insert plate 11 and the slot 12, an auxiliary fixation is formed at the connection between the short side plate 2 and the long side plate 3, which enhances the stability of the connection between the two. When the long side plate 3 is erected, the bottom side of the limiting plate 5 abuts against the top side of the baffle 6, which provides vertical support and limitation for the long side plate 3. At the same time, the limiting block 7 on the baffle 6 is inserted into the limiting groove 8 of the long side plate 3, which limits the long side plate 3 from the horizontal direction and prevents the long side plate 3 from shaking. When the short side plate 2 is erected, the limiting block 10 at the bottom of the short side plate 2 is inserted into the limiting groove 14 of the base 1. Through the cooperation of the limiting block 10 and the limiting groove 14, the connection between the short side plate 2 and the base 1 is positioned and limited, which enhances the stability of the short side plate 2.

[0034] When folding is required, by pulling the pull ring 21 at the other end of the sliding plate 18, the fixing block 22 can be disengaged from the fixing groove 23, thereby releasing the fixation between the short side plate 2 and the long side plate 3. Then, the short side plate 2 and the long side plate 3 are rotated in the opposite direction, so that the hinge rod 13 rotates in the hinge groove 24 and the hinge rod 28 rotates in the hinge groove 25 in the opposite direction until the folding operation is completed.
