Description

Technical Field

[0001] This utility model relates to the field of box technology, and in particular to a box side panel folding and limiting structure. Background Technology

[0002] To save storage and transportation space, foldable boxes or containers are widely used in logistics, warehousing and daily life. The side panels of these boxes are usually connected to the main body of the box by hinges or other structures so that they can be folded inward for storage when not in use.

[0003] However, in existing technical practices, the stability of the side panels often becomes a critical issue when the container is unfolded for use. Many simple folding structures can only enable the side panels to rotate and unfold, but cannot provide a secure lock after unfolding. This causes the side panels to easily shake, misalign, or even accidentally fold inward when subjected to external impact or squeezed by the cargo inside the container, seriously affecting the structural strength and safety of the entire container.

[0004] To address this issue, some designs have introduced independent manual locking mechanisms such as pins, clips, or bolts. While these mechanisms enhance the stability of the side panels to some extent, they typically require users to perform additional locking operations after unfolding the side panels and unlocking operations before folding them. This process is cumbersome and reduces ease of use. Furthermore, these separate or small locking mechanisms are at risk of being lost. Therefore, existing technologies generally lack an integrated structure that can ensure a smooth folding process and automatically and reliably limit and lock the side panels after unfolding.

[0005] Therefore, this utility model proposes a box side panel folding and limiting structure to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology where the side panels of the box are unstable and easy to shake after unfolding, and the folding operation is inconvenient, this utility model aims to provide a box side panel folding and limiting structure with improved structure that can effectively solve the above problems.

[0007] This utility model provides a box side panel folding limiting structure, including: a first side panel, a second side panel and a top panel, as well as a folding component, a fixing component and a slot.

[0008] The folding assembly includes a first fixing block, a second fixing block, a first connecting rod, a first rotating shaft, a second rotating shaft, a second connecting rod, a third rotating shaft, and a fourth rotating shaft. The folding assembly connects the first side plate and the second side plate together in a foldable manner through the linkage of the connecting rods and rotating shafts inside.

[0009] Furthermore, the fixing component includes an L-shaped locking block, an F-shaped plate, a connecting plate, a fixing post, and a spring. The spring is located above the F-shaped plate, the L-shaped locking block is connected to the F-shaped plate, and the connecting plate is connected to the F-shaped plate. The fixing component uses the L-shaped locking block to engage with the slot on the second side plate under the action of the spring, thereby limiting and fixing the unfolded second side plate to the top plate.

[0010] Preferably, the fixing component further includes a connecting block, which is disposed between the L-shaped card block and the F-shaped plate to reliably assemble and connect the L-shaped card block and the F-shaped plate, ensuring that the two move synchronously.

[0011] Preferably, the fixing assembly includes two fixing posts, and the spring is installed between the two fixing posts, providing a stable support base for the installation and effective compression and reset of the spring.

[0012] Preferably, in order to enhance the strength and smoothness of the folding mechanism, the folding assembly includes two cross-arranged first and second links, symmetrically connected between the first and second side plates.

[0013] Preferably, in order to define the installation reference of the fixing component, the fixing component is installed on the top plate so that it is in a suitable position when the box is unfolded to cooperate with the locking of the second side plate.

[0014] Preferably, in order to achieve effective transmission of elastic force to the locking structure, the F-shaped plate abuts against the spring. When unlocking is required, pressing the connecting plate will cause the F-shaped plate to move against the elastic force of the spring.

[0015] Preferably, the box side panel folding limiting structure further includes a handle, which is fixedly connected to the outside of the second side panel, providing a convenient point of force for the user when unfolding or folding the side panel.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that the side panel of the box is unstable after unfolding and is prone to shaking or folding under external force or vibration by setting a fixing component and making the L-shaped block in the fixing component automatically engage with the slot opened on the second side panel under the elastic force of the spring. It achieves the technical effect of automatically locking the side panel and enhancing the structural stability and reliability of the box in the unfolded state.

[0018] 2. This utility model, by setting a folding component, uses its internal multi-bar linkage mechanism to guide the folding and unfolding of the first side plate and the second side plate, which solves the problems of the side plate folding and unfolding process being not smooth and lacking effective angle restriction in the prior art. It achieves the technical effect of making the side plate move smoothly and smoothly, and can achieve automatic limiting through the geometric relationship of the mechanism to prevent excessive rotation.

[0019] 3. This utility model solves the problem of complex unlocking operations of some locking structures that require tools or cumbersome steps by setting a connecting plate and an F-shaped plate on the fixed component. It can quickly unlock without tools, and the operation is simple and fast, which improves the convenience of folding and storing the box. Attached Figure Description

[0026] 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.

[0027] Please refer to Figures 1 to 4 This utility model provides a box side panel folding limiting structure, which aims to solve the problems of unstable structure, easy shaking and folding back after the box side panel is unfolded, and the lack of smooth folding and unfolding process and limiting in the prior art.

[0028] like Figure 1 As shown, the box side panel folding limiting structure includes a first side panel 1, a second side panel 2 and a top panel 5. The structure also includes a folding assembly 3 connected between the first side panel 1 and the second side panel 2, a fixing assembly 6 for limiting and fixing the second side panel 2 and the top panel 5, a slot 607 opened on the second side panel 2, and a handle 4 fixedly connected to the outside of the second side panel 2.

[0029] Reference Figure 1 and Figure 2 The folding assembly 3 is used to realize the rotatable connection and unfolding positioning between the first side plate 1 and the second side plate 2. The folding assembly 3 includes a first fixing block 301, a second fixing block 302, a first connecting rod 303, a first rotating shaft 304, a second rotating shaft 305, a second connecting rod 306, a third rotating shaft 307, and a fourth rotating shaft 308. The first fixing block 301 is fixedly connected to the inner side of the first side plate 1, the second fixing block 302 is fixedly connected to the inner side of the second side plate 2, one end of the first connecting rod 303 is rotatably connected to the first side plate 1 through the first rotating shaft 304, and the middle part is connected to the first connecting rod 306 through the first connecting rod 307. The second pivot 305 is rotatably connected to the first side plate 1 to form an auxiliary fulcrum. One end of the second connecting rod 306 is hinged to the second side plate 2 through the third pivot 307, and the other end is rotatably connected to the first connecting rod 303 and the second side plate 2 through the fourth pivot 308. Through the above structure, the first fixing block 301 and the second fixing block 302 are connected to each other through a linkage mechanism to form a foldable multi-bar linkage mechanism. In this embodiment, preferably, the folding assembly 3 includes two cross-arranged first connecting rods 303 and second connecting rods 306 to enhance the stability of the folding and unfolding process.

[0030] The fixing component 6 is installed on the top plate 5. The fixing component 6 consists of an L-shaped locking block 601, a connecting block 602, an F-shaped plate 603, a connecting plate 604, a fixing post 605, and a spring 606. The L-shaped locking block 601 and the F-shaped plate 603 are configured to limit, support, and fix the edge of the second side plate 2. In this embodiment, the fixing component 6 includes two fixing posts 605, and the spring 606 is installed between the two fixing posts 605 to form an elastic reset mechanism. Preferably, the spring 606 is connected between the two fixing posts 605. The spring 606 is provided above the F-shaped plate 603. The L-shaped locking block 601 is connected to the F-shaped plate 603, the connecting plate 604 is connected to the F-shaped plate 603, and the connecting block 602 is connected between the L-shaped locking block 601 and the F-shaped plate 603.

[0031] Meanwhile, in the assembled state, when the side panel is unfolded to the working position along the folding assembly 3, the L-shaped locking block 601 automatically springs into the locking slot 607 under the elastic force of the spring 606, thereby locking and positioning the side panel. This locking and engaging structure of the L-shaped locking block 601 and the locking slot 607 ensures that it can prevent shaking or folding under external force or vibration, thus ensuring a stable connection between the side panel and the housing.

[0032] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0033] In a preferred embodiment, in order to further enhance the structural strength and smoothness of the folding and unfolding process, the folding assembly 3 includes two cross-arranged first links 303 and second links 306. These two links are symmetrically distributed in the connection area between the first side plate 1 and the second side plate 2, and share the weight and motion load of the side plates.

[0034] As another preferred embodiment, in order to achieve stable installation and reliable reset of the fixing component 6, the fixing component 6 includes two fixing posts 605, and a spring 606 is installed between the two fixing posts 605. More specifically, the spring 606 is sleeved on the fixing posts 605, and its two ends abut against the base portion of the two fixing posts 605 respectively, providing a stable and directional elastic force for the F-shaped plate 603.

[0035] In another preferred embodiment, in order to effectively transmit the elastic force to the L-shaped locking block 601, the F-shaped plate 603 abuts against the spring 606. When the fixing component 6 is in the natural state, the spring 606 pushes the F-shaped plate 603, thereby causing the L-shaped locking block 601 to remain in the extended locking ready position.

[0036] In another preferred embodiment, in order to achieve a reliable connection between the components, the fixing assembly 6 further includes a connecting block 602, which is disposed between the L-shaped locking block 601 and the F-shaped plate 603, and securely connects the two between the L-shaped locking block 601 and the F-shaped plate 603.

[0037] In another preferred embodiment, in order to clarify the installation position relationship of each component, the fixing component 6 is installed on the top plate 5. When the second side plate 2 is unfolded to the working position adjacent to the top plate 5, the L-shaped locking block 601 can be aligned with the locking slot 607 and locked in.

[0038] In another preferred embodiment, to facilitate user operation, the structure also includes a handle 4, which is fixedly connected to the outside of the second side panel 2, providing a convenient point of force for the user when folding or unfolding the side panel.

[0039] The working principle of the box side panel folding and limiting structure of this utility model is as follows:

[0040] When the side panel of the box needs to be unfolded, the operator pulls the handle 4 to rotate the second side panel 2 outward. At this time, the first connecting rod 303 and the second connecting rod 306 in the folding assembly 3 rotate in coordination under the guidance of the first rotating shaft 304, the second rotating shaft 305, the third rotating shaft 307 and the fourth rotating shaft 308, which drives the first side panel 1 and the second side panel 2 to unfold smoothly to the preset angle. The geometric relationship of the mechanism limits the unfolding angle and realizes automatic limit. When the unfolding is about to be in place, the edge of the second side panel 2 approaches the fixing assembly 6 and pushes the L-shaped locking block 601. When the second side panel 2 is fully unfolded to the working position, the L-shaped locking block 601 is pushed by the elastic force of the spring 606, and automatically springs into the locking groove 607 opened on the second side panel 2 through the F-shaped plate 603 and the connecting block 602 to complete the locking, thereby ensuring that the side panel and the box form a stable connection.

[0041] When the case needs to be folded, the operator presses the connecting plate 604. The connecting plate 604 causes the F-shaped plates 603 on both sides to separate under force and compress the spring 606. This action forces the L-shaped locking block 601 out of the slot 607 through the connecting block 602, thus unlocking the case. At this time, the second side plate 2 is no longer locked. The operator can push the handle 4 inward, and the linkage mechanism of the folding component 3 rotates in the opposite direction, causing the first side plate 1 and the second side plate 2 to gradually approach each other and achieve parallel fitting, finally completing the folded state. The entire operation process does not require the use of external tools, and the disassembly and assembly are convenient and the operation is smooth.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
