Description

Technical Field

[0001] This utility model relates to the field of container transportation technology, and in particular to a fixing device for folding containers. Background Technology

[0002] Folding crates are widely used in the logistics and transportation industry. When transporting goods, empty folding crates are often stacked to save space and reduce transportation costs. Folding crates have corner fitting holes at the four corners of the top and bottom panels for easy stacking with pins. For some types of folding crates, the corner fitting holes remain at the top four corners of the folded crate after folding.

[0003] Forklifts are commonly used in the logistics industry for lifting and transferring workpieces, replacing manual labor in moving large workpieces. When using a forklift, the workpiece is first securely clamped using forklift clamps, and then the clamps are connected to the forklift to ensure the stability and safety of the forklift operation.

[0004] Existing forklift clamps typically consist of two clamping plates that hold the folding box in place. This structure not only requires high stability and tightness from the clamping plates, increasing manufacturing and maintenance costs, but also makes the folding box prone to loosening during handling due to unstable clamping. This can damage the box during transport, resulting in economic losses. Because folding boxes are large and heavy, they are also prone to slipping during handling if not securely fastened, affecting work efficiency and potentially causing safety accidents.

[0005] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0006] The purpose of this utility model is to provide a fixing device for folding boxes, which aims to solve the problem that existing forklift clamps cannot utilize the original corner hole structure of folding boxes, resulting in unstable clamping. It enables the reuse of the corner holes of folding boxes for fixing when transporting folding boxes by forklifts, thus achieving stable transportation of folding boxes.

[0007] To solve the above-mentioned technical problems, this utility model provides a fixing device for a folding box, comprising:

[0008] A frame body for abutting against the end of at least one folding box;

[0009] The positioning structure is provided at both ends of the bottom of the frame body. The positioning structure corresponds to the corner piece of the folding box. The folding box is clamped and fixed between the two positioning structures.

[0010] The positioning structure includes:

[0011] A movable pin has a first working position and a second working position relative to the bottom of the frame body; wherein, when the movable pin is in the first working position, one end of the movable pin is inserted into the corner fitting hole of the folding box; when the movable pin is in the second working position, one end of the movable pin is withdrawn from the corner fitting hole.

[0012] A support base is fixed to the bottom of the frame body, located between the two ends of the movable pin, and is provided with a guide channel that allows the movable pin to move.

[0013] Optionally, the support base includes a baffle;

[0014] The baffle is located on the outside of the corner piece, and the baffle is sandwiched between the movable pin and the corner piece;

[0015] The baffle is provided with a first through hole for the movable pin to pass through, and the first through hole forms part of the guide channel.

[0016] Optionally, the support base may further include a pin locking structure;

[0017] The pin-locking structure is spaced apart from the baffle, and the movable pin is clamped between the pin-locking structure and the baffle;

[0018] The pin locking structure is provided with at least one second through hole, which is used for the movable pin to pass through, and the second through hole forms part of the guide channel.

[0019] Optionally, the positioning structure further includes a limiting part;

[0020] The movable pin is equipped with a handle;

[0021] When the handle is pressed against the first side of the limiting part, the movable pin is in the first working position;

[0022] When the handle is pressed against the second side of the limiting part, the movable pin is in the second working position.

[0023] Optionally, the latching structure includes:

[0024] At least one pin positioning plate is provided, which is arranged parallel to the baffle and spaced at a certain distance. The pin positioning plate is provided with a second through hole that allows the movable pin to pass through.

[0025] Optionally, the pin locking structure includes a plurality of pin positioning plates, and one of the pin positioning plates is located at the end position of the bottom of the frame body.

[0026] Optionally, the pin locking structure further includes a limiting collar, which passes through each of the pin positioning plates and is accommodated in the second through hole, for guiding the horizontal movement of the movable pin.

[0027] Optionally, the main body of the framework includes:

[0028] A base frame; wherein the positioning structures are disposed at both ends of the base frame, and an accommodating space for accommodating one of the folding boxes is formed between the positioning structures at both ends;

[0029] A support frame is fixed to the base frame, and the length of the support frame is less than the length of the base frame.

[0030] Optionally, the supporting frame includes a rectangular frame, the length of which corresponds to the lateral length of the folding box.

[0031] Optionally, the frame body further includes a reinforcing member disposed at the connection position between the supporting frame and the base frame.

[0032] Through the above technical solution, this utility model has the following beneficial effects:

[0033] This invention, through the design of a frame body and a positioning structure, including a movable pin and a support base for limiting the movable pin, enables the folding box to be secured during transportation using the existing corner fitting holes. This solves the problem of insufficient stability in existing forklift clamps when holding folding boxes. The movable pin can flexibly switch between a first working position and a second working position relative to the bottom of the frame body. When inserted into the corner fitting holes of the folding box, it can firmly lock the box, preventing loosening or slippage during handling, thus improving the safety and stability of handling the folding box.

[0034] Furthermore, the baffle and pin locking structure further enhance the operational convenience and reliability of the entire fixing device. The baffle engages with the movable pin through the first through hole, guiding the movable pin while simultaneously abutting against the outer side of the folding box corner piece to form a fixation. The pin locking structure, through several pin positioning plates and limiting collars, provides multi-point support and precise guidance for the movable pin, making its horizontal movement more stable. The design of the limiting part and handle allows the operator to quickly and accurately adjust the working state of the movable pin, improving work efficiency. At the same time, the addition of reinforcing components enhances the structural strength of the entire device, making it suitable for supporting heavy folding boxes. Attached Figure Description

[0042] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0043] Please refer to Figure 1 - Figure 2 This embodiment provides a fixing device for a folding case, including: a frame body 1 and positioning structures. The frame body 1 is used to abut against the end of at least one folding case; the positioning structures are disposed at both ends of the bottom of the frame body 1, and the positioning structures correspond to the corner pieces of the folding case, and the folding case is clamped and fixed between two of the positioning structures.

[0044] The positioning structure includes a movable pin 22 and a support base. The movable pin 22 has a first working position and a second working position relative to the bottom of the frame body 1; wherein, when the movable pin 22 is in the first working position, one end of the movable pin 22 is inserted into the corner fitting hole of the folding box; when the movable pin 22 is in the second working position, the movable pin 22 is withdrawn from the corner fitting hole; the support base is fixed to the bottom of the frame body, located between the two ends of the movable pin 22, and has a guide channel that allows the movable pin 22 to move.

[0045] It should be noted that the movable pin 22 is in a locked state when it is in the first working position. Figure 1 - Figure 2 This is a schematic diagram of the movable pin 22 in the second working position, at which time the fixing device is in the unlocked state.

[0046] In this embodiment, the movable pin 22 engages with the corner fitting holes of the folding box, and the support base provides guidance and support, jointly achieving a stable fixation of the folding box. The support base is located between the two ends of the movable pin 22. Through the guide channel provided on the support base, the movable pin 22 can move along a predetermined path and be fixed and stored, providing support for the movable pin 22 while improving the pin's positioning accuracy. Switching the working position of the movable pin 22 allows the folding box to be quickly locked when needed and easily unlocked when needed. Therefore, this fixing device not only improves the safety of the folding box during handling but also simplifies the operation process and increases work efficiency; it also fully utilizes the original corner fitting hole structure of the folding box, avoiding loosening problems caused by unstable clamping.

[0047] It is worth mentioning that when transporting folding crates, the fixing device in this embodiment is fixed to the forklift, and then the movable pin of the fixing device is used to lock the fixing device to the folding crate, thus securing one folding crate. When transporting multiple folding crates, the bottom folding crate is first connected and fixed to the fixing device in the above manner, and then the other folding crates are stacked on top of the bottom folding crate, thereby enabling the forklift to transport one or more folding crates at a time. Alternatively, when transporting at least one folding crate and other crate accessories (such as interior decoration parts, wall panels, etc. of a housing crate), the bottom folding crate can also be connected and fixed to the fixing device in the above manner, and then the other folding crates and accessories are stacked and fixed on top of the bottom folding crate, thereby enabling the forklift to transport one or more folding crates and accessories at a time.

[0048] For further details, please refer to... Figure 1 and Figure 3 The support base includes a baffle 21 located outside the corner piece, sandwiched between the movable pin 22 and the corner piece of the folding case. The baffle 21 has a first through hole for the movable pin 22 to pass through, forming part of the guide channel. In the first working position, one end of the movable pin 22 passes through the first through hole and inserts into the corner piece hole of the folding case it abuts.

[0049] In this embodiment, the movable pin 22 passes through the first through hole of the baffle 21 and is inserted into the corner fitting hole of the folding box. At the same time, the baffle 21 is pressed against the outside of the corner fitting of the folding box to form an abutment. The two work together to achieve a stable positioning and fixation of the folding box. The baffle 21 can pre-limit the folding box to be transported, which facilitates the subsequent fixing of the movable pin 22 with the corner fitting hole of the folding box, thereby improving the efficiency of the fixing operation.

[0050] For further information, please refer to the following: Figure 2 The support base also includes a pin locking structure 23, which is spaced apart from the baffle 21. The movable pin 22 is clamped between the pin locking structure 23 and the baffle 21. The pin locking structure 23 is provided with at least one second through hole for the movable pin 22 to pass through, and the second through hole constitutes part of the guide channel.

[0051] It is worth mentioning that the support base can also be a pipe structure, located on the side of the movable pin away from the corner piece of the folding box. The movable pin part is housed in the pipe structure of the support base and can be switched between the first working position and the second working position.

[0052] In this embodiment, the pin locking structure 23 provides limiting, support, guidance and storage for the movable pin 22, making the movement of the movable pin 22 in the horizontal direction more stable and reliable, improving its accuracy and reliability when switching between the first working position and the second working position. The movable pin 22 can be stored in the pin locking structure 23 in the second working position, minimizing the possibility of the movable pin 22 coming out and ensuring the integrity of the fixing device components.

[0053] Furthermore, the positioning structure also includes a limiting part 3, and the movable pin 22 is provided with a handle 221; when the handle 221 abuts against the first side of the limiting part 3, the movable pin 22 is located in the first working position; when the handle 221 abuts against the second side of the limiting part 3, the movable pin 22 is located in the second working position.

[0054] In this embodiment, the limiting part 3 is used to divide the first working position and the second working position, ensuring that the movable pin 22 can stably switch between the two clearly defined working positions, and also preventing the movable pin 22 from moving or sliding unexpectedly during use.

[0055] The handle 221 is disposed on the pin body, and the pin body can move horizontally between the baffle 21 and the pin locking structure 23 as the handle moves; the handle 221 allows the operator to easily control the position switching of the movable pin 22.

[0056] In this embodiment, the pin body has a cylindrical structure, and its outer diameter matches the inner diameter of the corner fitting hole of the folding box, ensuring smooth insertion and a tight fit to prevent shaking during transportation. The length of the pin body is designed to be moderate, sufficient to pass through the baffle 21 and penetrate deep enough into the corner fitting hole of the folding box, while not being too long to affect operation. The end of the pin body can be designed as a slightly chamfered cone to facilitate guiding the pin into the corner fitting hole and improve operational convenience.

[0057] Furthermore, the specific implementation methods of the limiting part 3 may include, but are not limited to, the following:

[0058] The limiting part 3 can be a limiting block fixed to the frame body 1. The limiting block has a groove that matches the shape of the handle 221. The depth and width of the groove limit the movement range of the handle 221, thereby limiting the position of the movable pin 22. Alternatively, the limiting part 3 can be a limiting rod provided on the frame body 1. The limiting rod has a limiting groove that mates with the handle 221. The position and length of the limiting groove limit the movement range of the handle 221. Furthermore, the limiting part 3 can also be a limiting pin provided on the frame body 1. The limiting pin limits the movement range of the handle 221 by inserting into or retracting from the limiting hole.

[0059] In a specific example, a first limiting space is formed between the limiting part 3 and the baffle 21, and a second limiting space is formed between the limiting part 3 and the pin locking structure 23. When the handle 221 is located in the first limiting space, the movable pin 22 is in the first working position; when the handle 221 is located in the second limiting space, the movable pin 22 is in the second working position.

[0060] The limiting part 3 forms a limiting space with the baffle 21 and the pin locking structure 23 respectively, so that the movement range of the movable pin 22 is precisely controlled, avoiding the displacement of the movable pin 22 during operation. This not only improves the stability and safety of the fixing device, but also simplifies the operation process.

[0061] Preferably, the width of the handle 221 matches the width of the first defined space. When the handle 221 is in the first defined space, it can be tightly accommodated, further enhancing the stability of the movable pin 22 in the first working position and preventing the movable pin 22 from accidentally dislodging during the handling of the folding box.

[0062] As a preferred embodiment, the handle 221 can be designed to be rotatable or slidable to facilitate quick switching between different working positions by the operator. Furthermore, the limiting part 3 can be made of a spring or magnetic material to enhance the fixing effect of the movable pin 22 within the defined space.

[0063] Furthermore, the pin locking structure 23 includes at least one pin positioning plate 231, which is arranged parallel to and spaced a certain distance from the baffle 21. The pin positioning plate 231 has a second through hole that allows the movable pin 22 to pass through. The pin positioning plate 231 provides multi-point support for the movable pin 22, improving the stability of the movable pin 22 during horizontal movement.

[0064] Furthermore, the pin locking structure 23 includes a plurality of pin positioning plates 231, one of which is located at the end of the bottom of the frame body 1. The pin positioning plate 231 located at the end of the bottom of the frame body 1 provides end support and limitation for the movable pin 22.

[0065] Multiple pin positioning plates 231 are spaced apart along the axial direction of the movable pin 22, and their through holes are connected.

[0066] Furthermore, the pin locking structure 23 also includes a limiting collar 232, which passes through each of the pin positioning plates 231 and is accommodated in the second through hole, further serving to guide the horizontal movement of the movable pin 22.

[0067] In one specific example, there are three pin positioning plates 231, arranged at intervals.

[0068] In this embodiment, multiple pin positioning plates 231 are spaced apart and multiple second through holes are connected to provide multi-point support for the movable pin 22. The limiting collar 232 provides guidance for the movement of the movable pin 22, making its horizontal movement smoother and preventing it from deviating from the predetermined path.

[0069] Furthermore, the frame body 1 includes a base frame 11 and a supporting frame 12. The base frame 11 has positioning structures at both ends, forming an accommodating space for accommodating a folding box between the positioning structures at both ends. The supporting frame 12 is fixed to the base frame 11, and the length of the supporting frame 12 is less than the length of the base frame 11. The base frame 11 and the supporting frame 12 ensure that the fixing device for the folding box has sufficient strength and stability.

[0070] Furthermore, the supporting frame 12 includes a rectangular frame, the length of which corresponds to the lateral length of the folding box, ensuring that the folding box can be securely placed on the fixing device. It is worth mentioning that the supporting frame 12 facilitates the fixing device's attachment to the forklift, and also provides support and protection for the folding box or box accessories located above the bottom folding box when transporting multiple folding boxes or one folding box with multiple box accessories, preventing direct contact with the forklift.

[0071] Furthermore, the fixing device for the folding box also includes a reinforcing member 4, which is disposed at the connection position between the supporting frame 12 and the base frame 11, further enhancing the structural strength of the fixing device and improving the stability and safety of the device when bearing heavy folding boxes.

[0072] In practical use, the fixing device for folding boxes provided in this embodiment can be used with a forklift. The folding box is placed in the accommodating space, with the corner pieces of the folding box abutting against the baffle 21, and the corner piece holes of the folding box corresponding to the movable pin 22. By operating the handle 221, the movable pin 22 is switched from the second working position to the first working position. One end of the movable pin 22 passes through the first through hole of the baffle 21 and inserts into the corner piece hole of the folding box, thereby firmly fixing the folding box to the fixing device. After fixing, the forklift can safely lift and move the fixing device and the folding box on it. When it is necessary to remove the folding box, simply move the handle 221 from the first side of the limiting part 3 to the second side of the limiting part 3, so that the movable pin 22 returns to the second working position and exits from the corner piece hole of the folding box, thus releasing the fixing.

[0073] In summary, this utility model provides a fixing device for folding boxes. Through a positioning structure including a movable pin and a support base, it effectively utilizes the original corner fitting hole structure of the folding box to fix it, solving the problem of unstable clamping caused by existing forklift clamps being unable to utilize the original corner fitting hole structure. The movable pin's switching between the first and second working positions, combined with the limiting part and handle, makes switching between the locked and unlocked states of the device simple and intuitive. The baffle and pin locking structure in the support base form guide channels through the first and second through holes, respectively, providing good support and guidance for the movable pin, making its movement more stable and reliable. The frame body and reinforcing members give the entire device sufficient strength and stability, enabling it to safely support heavy folding boxes and prevent accidents during handling. The device provided by this utility model has a simple structure, low manufacturing cost, and is easy to maintain.

[0074] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
