Description

Technical Field

[0001] This invention relates to the technical field of turnover boxes, and in particular to a foldable and combinable turnover box cabinet structure. Background Technology

[0002] A turnover box is a multi-functional container used for storing and transporting goods. It is widely used in logistics, manufacturing, warehousing and other industries. It is usually made of high-strength plastic, metal or composite materials and is lightweight, durable, impact-resistant and easy to clean. The design of turnover boxes focuses on practicality and high utilization of internal space. It can effectively protect goods and prevent damage. However, most turnover boxes are fixed structures. Fixed turnover boxes still occupy a lot of space when not in use, which increases warehousing costs. During transportation, empty turnover boxes also occupy valuable transportation space, resulting in reduced transportation efficiency and increased costs. Therefore, there is a particular need for a foldable and combinable turnover box cabinet structure.

[0003] However, most existing turnover box and cabinet structures do not fold effectively during use. The non-folding design makes the storage and handling of turnover boxes inflexible, which is not conducive to the modern logistics industry's demand for efficiency and flexibility, and may ultimately affect the company's operational efficiency and competitiveness. Summary of the Invention

[0004] The purpose of this invention is to provide a foldable and combinable turnover box structure to solve the problems mentioned in the background art. In use, the existing turnover box structures have poor folding and combinating effects, and the non-foldable design makes the storage and handling of turnover boxes inflexible, which is not conducive to the modern logistics industry's demand for efficiency and flexibility, and may ultimately affect the company's operational efficiency and competitiveness.

[0005] To achieve the above objectives, the present invention provides a foldable and combinable turnover box cabinet structure, including a turnover box shell and a folding and combinating mechanism. A turnover box base is fixedly connected to the top surface of the turnover box shell, and an inner column of the turnover box is fixedly connected to the top surface of the turnover box base. The folding and combinating mechanism is provided on the outer surface of the turnover box shell, and an internal adjustment mechanism is provided on the outer surface of the turnover box base.

[0006] Preferably, the outer shell of the turnover box is a slotted shape with hollowed-out sides, and there are two turnover box outer shells and turnover box bases, which are symmetrically distributed. The height of the inner column of the turnover box matches the height of the turnover box outer shell.

[0007] Preferably, the folding assembly mechanism includes a connecting latch, a rotating shaft, a first rotating side plate, a hinge structure, and a second rotating side plate. The bottom surface of the turnover box shell is fixedly connected to the connecting latch, the outer surface of the turnover box shell is fixedly connected to the rotating shaft, the outer surface of the rotating shaft is rotatably connected to the first rotating side plate, the top surface of the first rotating side plate is fixedly connected to the hinge structure, and the other side surface of the hinge structure is fixedly connected to the second rotating side plate.

[0008] Preferably, the two parts of the connecting latch are fixedly connected to the outer shell of the turnover box on one side, and the rotating shaft is symmetrically distributed on both sides of the outer shell of the turnover box.

[0009] Preferably, the hinge structure consists of hinges fixed on the first rotating side plates on both sides, and the first rotating side plates are provided with protrusions for mounting the hinges and grooves for storing the hinges.

[0010] Preferably, the internal adjustment mechanism includes a connecting hole, a hinge rod, an inner box, a rotating wheel, and a locking claw. The outer surface of the turnover box base is provided with a connecting hole, the inner surface of the connecting hole is slidably connected to the hinge rod, the top surface of the hinge rod is fixedly connected to the inner box, the bottom surface of the hinge rod is rotatably connected to the rotating wheel, and the bottom surface of the turnover box base is fixedly connected to the locking claw.

[0011] Preferably, the number of connecting holes is four and they are symmetrically distributed, and the connecting holes penetrate through the base of the turnover box.

[0012] Preferably, the bottom of the inner box is square and only two sides are equipped with side plates that are perpendicular to each other. The locking claw is made of PP plastic and is engaged with the hinge rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The foldable and combinable turnover box structure, through the setting of the folding and combing mechanism, allows the turnover boxes to be easily folded and stacked during use by means of the connecting locks, rotating shafts and hinge structures, saving space, reducing the floor area, facilitating storage and transportation, improving space utilization, and reducing the volume of the folded turnover box, thus reducing space waste during transportation and lowering transportation costs. The enclosed space formed can effectively protect the internal items and prevent damage during handling and storage. Through the design of the rotating side panels and the hinge structure, multiple turnover boxes can be stably combined, facilitating batch processing and movement. The hinge structure allows the first and second rotating side panels to rotate around the connection point, enabling the turnover boxes to be flexibly unfolded or folded when needed, adapting to different usage requirements and scenarios. The connecting locks and rotating mechanism make the folding and unfolding process simple and easy, making the turnover boxes more flexible, efficient and economical in use and storage, suitable for the needs of modern logistics and warehousing management.

[0014] The inner box is connected to the base of the turnover box via a hinged rod and connecting holes. The inner box can be rotated to create different compartments for categorization by altering its sides. When the inner box needs to be rotated, the hinged rod is detached from the locking claws. The hinged rod then rotates into a vertical column, lifting the inner box. The hinged rod can then rotate within the connecting holes, causing the inner box to rotate. The rotating wheel on the hinged rod has a radial dimension larger than the hinged rod, acting as a limit to prevent the hinged rod from falling out of the connecting holes. After rotation, the inner box is placed back in, and the inner boxes and the outer shell of the turnover box will lock together to maintain the current state. The hinged rod then bends back to the bottom and is locked by the locking claws. At this point, the rotating wheel is perpendicular to the ground and can be used as a wheel, achieving the effect of easily changing the internal compartments of the box for categorized storage.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-8 The present invention provides a foldable and combinable turnover box cabinet structure: including a turnover box shell 1 and a folding and combinating mechanism 4. A turnover box base 2 is fixedly connected to the top surface of the turnover box shell 1, and an inner column 3 of the turnover box is fixedly connected to the top surface of the turnover box base 2. The folding and combinating mechanism 4 is provided on the outer surface of the turnover box shell 1, and an internal adjustment mechanism 5 is provided on the outer surface of the turnover box base 2.

[0026] Furthermore, the outer shell 1 of the turnover box is a slot-shaped structure with open sides. There are two turnover box outer shells 1 and turnover box bases 2, which are symmetrically distributed. The height of the turnover box inner column 3 matches the height of the turnover box outer shell 1.

[0027] Furthermore, the folding assembly mechanism 4 includes a connecting latch 401, a rotating shaft 402, a first rotating side plate 403, a hinge structure 404, and a second rotating side plate 405. The connecting latch 401 is fixedly connected to the bottom surface of the turnover box shell 1. The rotating shaft 402 is fixedly connected to the outer surface of the turnover box shell 1. The first rotating side plate 403 is rotatably connected to the outer surface of the rotating shaft 402. The hinge structure 404 is fixedly connected to the top surface of the first rotating side plate 403. The second rotating side plate 405 is fixedly connected to the other side surface of the hinge structure 404. Through the arrangement of the connecting latch 401, rotating shaft 402, first rotating side plate 403, hinge structure 404, and second rotating side plate 405, during use, when folding is not required, the turnover box shell 1 and the turnover box base 2 are connected by the bottom connecting latch 401 to prevent them from separating. The turnover box shell 1 is connected to the first rotating side plate 403 via the rotating shaft 402. Furthermore, it can rotate around the connection point. At the same time, the first rotating side plate 403 is also connected to the second rotating side plate 405 through the hinge structure 404 and rotates around the connection point. In this way, when the connecting lock 401 is released, the outer shell 1 and the base 2 of the turnover box on both sides can rotate around the hinge structure 404, and the outer shell 1 and the base 2 of the turnover box on both sides can be folded and stacked, which can effectively reduce the floor space and form a closed space to play a protective role. When multiple turnover boxes need to be connected, the first rotating side plate 403 is rotated through the rotating shaft 402. The first rotating side plate 403 and the second rotating side plate 405 fit tightly with the outer shell 1 of the turnover box, which will clamp the inner outer shell 1 of the turnover box. It will not move when there is no external force. The first rotating side plate 403 can be rotated to clamp the outer shell 1 of another turnover box with the second rotating side plate 405, and multiple turnover boxes can be combined to achieve the effect of folding combination.

[0028] Furthermore, the two parts of the connecting buckle 401 are fixedly connected to the outer shell 1 of the turnover box on one side, and the rotating shaft 402 is symmetrically distributed on both sides of the outer shell 1 of the turnover box. The outer shell 1 of the turnover box and the base 2 of the turnover box are connected by the connecting buckle 401 at the bottom to prevent them from falling apart. The symmetrical rotating shaft 402 is equipped with symmetrical first rotating side plates 403, which can be clamped on both sides.

[0029] Furthermore, the hinge structure 404 is composed of hinges fixed on the first rotating side plates 403 on both sides, and the first rotating side plates 403 are provided with protrusions for installing hinges and grooves for storing hinges. The turnover box shell 1 and turnover box base 2 on both sides can rotate around the hinge structure 404, and the turnover box shell 1 and turnover box base 2 on both sides can be folded and stacked. The grooves are used to store the protrusions for installing hinges.

[0030] Furthermore, the internal adjustment mechanism 5 includes a connecting hole 501, a hinge rod 502, an inner box 503, a rotating wheel 504, and a locking claw 505. The outer surface of the turnover box base 2 has a connecting hole 501. The hinge rod 502 is slidably connected to the inner surface of the connecting hole 501. The top surface of the hinge rod 502 is fixedly connected to the inner box 503. The bottom surface of the hinge rod 502 is rotatably connected to the rotating wheel 504. The bottom surface of the turnover box base 2 is fixedly connected to the locking claw 505. Through the arrangement of the connecting hole 501, hinge rod 502, inner box 503, rotating wheel 504, and locking claw 505, during use, the bottom of the inner box 503 is square, and only two sides are fitted with side plates that are perpendicular to each other. It is connected to the turnover box base 2 via the hinge rod 502 and the connecting hole 501. The inner box 503 can be rotated to adjust the turnover box base 2. The inner box 503 is divided into different compartments for classification by its different sides. When the inner box 503 needs to be rotated, the hinge rod 502 is removed from the locking claw 505. At this time, the hinge rod 502 can be rotated into a vertical column to lift the inner box 503. The hinge rod 502 can rotate in the connecting hole 501 and drive the inner box 503 to rotate. The radial dimension of the rotating wheel 504 on the hinge rod 502 is larger than that of the hinge rod 502, which plays a limiting role to prevent the hinge rod 502 from falling out of the connecting hole 501. After the rotation is completed, the inner box 503 is put back in. The inner boxes 503 and the outer shell 1 of the turnover box will be locked together to maintain the current state. The hinge rod 502 is bent to the bottom again and locked by the locking claw 505. At this time, the rotating wheel 504 is perpendicular to the ground and can be used as a wheel, which achieves the effect of easily changing the internal partition space of the box to realize classified storage.

[0031] Furthermore, there are four connecting holes 501, which are symmetrically distributed. The connecting holes 501 penetrate the base 2 of the turnover box, and multiple inner boxes 503 are installed through multiple connecting holes 501 to achieve different separation methods.

[0032] Furthermore, the bottom of the inner box 503 is square and only two sides are equipped with side plates that are perpendicular to each other. The locking claws 505 are made of PP plastic and are engaged with the hinge rods 502. By rotating the inner box 503, different sides are separated to form different compartments for classification. The locking claws 505 are made of plastic and have a certain degree of elasticity, which can lock the hinge rods 502 and be removed when needed.

[0033] Working Principle: A foldable and combinable turnover box cabinet structure. During use, when not folding, the turnover box shell 1 and the turnover box base 2 are connected by a bottom connecting latch 401 to prevent them from falling apart. The turnover box shell 1 is connected to a first rotating side plate 403 via a rotating shaft 402 and can rotate around the connection point. At the same time, the first rotating side plate 403 is also connected to a second rotating side plate 405 via a hinge structure 404 and can rotate around the connection point. Thus, when the connecting latch 401 is opened, the turnover box shell 1 and the turnover box base 2 on both sides... All can be rotated around the hinge structure 404, and the outer shell 1 and base 2 of the turnover box on both sides can be folded and stacked. When multiple turnover boxes need to be connected, the first rotating side plate 403 is rotated through the rotating shaft 402. The first rotating side plate 403 and the second rotating side plate 405 fit tightly with the outer shell 1 of the turnover box, clamping the inner outer shell 1 of the turnover box. It will not move when not subjected to external force. The first rotating side plate 403 can be rotated so that it clamps the outer shell of another turnover box with the second rotating side plate 405. 1. Multiple turnover boxes are combined. The bottom of the inner box 503 is square, and only two side panels are installed on both sides perpendicular to each other. It is connected to the turnover box base 2 by a hinge rod 502 and a connecting hole 501. The inner box 503 can be rotated to separate different sides, forming different compartments for classification. When it is necessary to rotate the inner box 503, the hinge rod 502 is removed from the locking claw 505. At this time, the hinge rod 502 can be rotated into a vertical column, lifting the inner box 503. At this time, the hinge rod 502 can be connected to the connecting hole 501. The inner box 503 rotates, and the radial dimension of the rotating wheel 504 on the hinge rod 502 is larger than that of the hinge rod 502, which plays a limiting role to prevent the hinge rod 502 from falling out of the connection hole 501. After the rotation is completed, the inner box 503 is put in again. The inner boxes 503 and the outer shell 1 of the turnover box will be locked together to maintain the current state. The hinge rod 502 bends to the bottom again and is locked by the locking claw 505. At this time, the rotating wheel 504 is perpendicular to the ground and can be used as a wheel. This completes a foldable and combinable turnover box cabinet structure.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
