[0002] To protect product corners from impact during transport, packaging protectors are often installed on the corners of products, such as photovoltaic modules. These protectors are typically formed by folding the blank sheet. If they are not secured with glue or nails after folding, they can break apart and fall off. If the protectors fall off, repackaging is necessary, wasting time and effort. Utility Model Content

[0003] In order to overcome the problem in the prior art that the packaging corner protector is easily disintegrated and falls off, the utility model provides a packaging corner protector with a self-locking structure to prevent the packaging corner protector from disintegrating and falling off.

[0004] The foldable panel is constructed to accommodate a plurality of side panels, each of which is adapted to extend over the entirety of the packaging and to enable the packaging to extend over the packaging structure. The foldable panel is constructed to accommodate a plurality of side panels, each of which is adapted to extend over the entire packaging structure. The foldable panel is constructed to accommodate a plurality of side panels, each of which is adapted to extend over the entire packaging structure.

[0005] In the technical solution of the present application, a protective space is formed by enclosing the bottom plate, the first side plate, the second side plate, the first top plate and the second top plate, and a first limiting portion is formed at the folded connection between the folding plate and the second top plate. Since one end of the first top plate away from the first side plate is exposed outside the second top plate and is provided with a second limiting portion that is engaged with the first limiting portion, when the first top plate is about to detach from the bottom of the second top plate along the length direction of the second side plate, the second limiting portion will be engaged with the first limiting portion, thereby forming a self-locking function, effectively preventing the paper corner protector from disintegrating and falling off, without the need for gluing or nailing, easy to use and lower cost.

[0006] Furthermore, a dimension of the second limiting portion along the length direction of the first side plate is greater than a dimension of the second top plate in the same direction.

[0007] Furthermore, the first side panel and the bottom panel are foldably connected, and the second side panel and the bottom panel are foldably connected.

[0008] Furthermore, the folding plate includes a first folding portion and a second folding portion arranged along the length direction of the first side panel, one side of the first folding portion can be folded and connected to the second side panel, and the other side of the first folding portion can be folded and connected to the second folding portion, and the first folding portion and the second folding portion are both folded and placed below the first top panel.

[0009] In the above technical solution, the folding plate is divided into a first folding portion and a second folding portion that can be folded in sequence, so that the first folding portion and the second folding portion are placed below the first top plate. Through the secondary folding, the folding plate is not easily detached from below the first top plate, thereby preventing the packaging corner guard from loosening and disintegrating.

[0010] Furthermore, the folding plate has a larger dimension along the length direction of the first side plate than the second top plate in the same direction. In this solution, the longer folding plate has a larger vertical overlap with the second top plate after folding, making it less likely to come loose.

[0011] Furthermore, one side surface of the second folding portion is used to abut against the inner side surface of the product. In this solution, the second folding portion abuts against the inner surface of the frame, making it difficult to get loose.

[0012] Furthermore, the first top panel further includes a protective portion and a laminated portion. One side of the protective portion is folded and connected to the first side panel, the other side of the protective portion is connected to one side of the laminated portion, and the other side of the laminated portion is connected to the second stopper. In this embodiment, the protective portion is provided to protect the surface of the product near the protective portion, the laminated portion is used to mate with the second top panel, and the second stopper is connected to the side away from the first side panel to prevent loosening.

[0013] Furthermore, the second top plate is larger than the stacking portion in the length direction of the first side plate. In this embodiment, the second top plate can effectively cover the folding plate and leave a gap in this direction, so that the stacking plate has a certain amount of space to move and prevent tearing during assembly.

[0014] Furthermore, an anti-collision notch is provided at the junction of the bottom plate, the first side plate and the second side plate. In this solution, the first side plate and the second side plate can be prevented from being squeezed and collided with each other at this junction to cause deformation, thereby preventing the packaging corner protector from disintegrating and loosening.

[0015] The present invention also provides a packaging corner protector blank, which is used to fold to form the above-mentioned packaging corner protector, including a bottom plate, a first side plate, a second side plate, a first top plate, a second top plate, and a folding plate. The bottom plate has two adjacent sides, and the two sides form an L-shaped structure and respectively connect the first side plate and the second side plate. The side of the first side plate away from the bottom plate is connected to the first top plate, the side of the second side plate away from the bottom plate is connected to the second top plate, and the side of the second top plate away from the second side plate is connected to the folding plate. The size of the second top plate along the length direction of the first side plate is larger than the size of the first top plate in this direction, and the side of the first top plate away from the first side plate is provided with a second limiting portion, and the size of the second limiting portion along the length direction of the first side plate is larger than the size of the second top plate in this direction. In this solution, the above-mentioned packaging corner protector blank is used to fold to form the packaging corner protector, preventing it from loosening and disintegrating during use.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The packaging corner protector of the present invention forms a protective space by enclosing the bottom plate, the first side plate, the second side plate, the first top plate and the second top plate. The folding plate and the second top plate form a first limiting portion at the folded connection. Since one end of the first top plate away from the first side plate is exposed outside the second top plate and is provided with a second limiting portion that is engaged with the first limiting portion, when the first top plate is about to detach from the bottom of the second top plate along the length direction of the second side plate, the second limiting portion will be engaged with the first limiting portion, thereby forming a self-locking function, effectively preventing the paper corner protector from disintegrating and falling off, without the need for gluing or nailing, easy to use and lower cost.

[0027] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0028] Example 1

[0029] refer to Figure 1 、 Figures 3 to 5 , this embodiment discloses a packaging corner protector, including a bottom plate 1, the bottom plate 1 has two adjacent side edges, the two side edges form an L-shaped structure, the two side edges are respectively connected to a first side panel 2 and a second side panel 3 perpendicular to the bottom plate 1, the top of the first side panel 2 can be folded and connected to a first top panel 4, the top of the second side panel 3 can be folded and connected to a second top panel 5, the first top panel 4 and the second top panel 5 are both folded and covered on opposite surfaces of the bottom plate 1; wherein the second top panel 5 covers the top of the first top panel 4 and can be folded and connected to a folding plate 6, the folding plate 6 is folded toward the bottom plate 1 and placed under the first top panel 4, the folding plate and the second top panel form a first limiting portion at the folded connection, and one end of the first top panel 4 away from the first side panel 2 is exposed outside the second top panel 5 and is provided with a second limiting portion 41 that is clipped with the first limiting portion.

[0030] In the technical solution of the present application, a protective space is formed by enclosing the bottom plate 1, the first side plate 2, the second side plate 3, the first top plate 4 and the second top plate 5, and the folding plate 6 and the second top plate 5 form a first limiting portion at the folded connection. Since one end of the first top plate 4 away from the first side plate 2 is exposed outside the second top plate 5 and is provided with a second limiting portion 41 that is engaged with the first limiting portion, when the first top plate 4 is about to detach from the bottom of the second top plate 5 along the length direction of the second side plate 3, the second limiting portion 41 will be engaged with the first limiting portion, thereby forming a self-locking function, effectively preventing the paper corner protector from disintegrating and falling off, without the need for gluing or nailing, easy to use and lower cost.

[0031] The product can be, for example, a photovoltaic module or other product that requires corner protection. In this embodiment, the product is a photovoltaic module, and the corners of its frame are protected by packaging corner protectors. The packaging corner protectors are roughly right-angled and fit in place with the corners of the photovoltaic module frame. Figures 1 to 4 , using the illustrated direction as an example. The bottom plate 1 is attached to the bottom of the photovoltaic module frame, while the first and second side plates 2 and 3 are attached to two adjacent sides of the photovoltaic module frame, forming a right-angled wrapping. The first and second top plates 4 and 5 are partially stacked and attached to the top of the photovoltaic module frame. The second top plate 5 is pressed above the first top plate 4, and the folding plate 6 connected to the second top plate 5 is further folded inward of the photovoltaic module frame, thereby pressing the second top plate 5 against the first top plate 4. The rightmost end of the first top plate 4 extends beyond the second top plate 5 and has a second stopper 41. The second stopper can be, for example, a stopper buckle or a stopper protrusion. In this embodiment, the second stopper 41 is larger along the length of the first side plate 2 than the second top plate 5 in that direction. Therefore, when the first top plate 4 tends to separate from the second top plate 5 from the left, the second stopper 41 will abut against one side of the first stopper, forming a self-locking lock to prevent the packaging corner protector from disintegrating. The packaging corner protector of this embodiment does not need to be fixed by gluing or nailing, which can save costs and is easy to use.

[0032] Preferably, the side of the second limiting portion 41 close to the second side plate 3 is flush with the second top plate 5, and the side of the second limiting portion 41 away from the second side plate 3 exceeds the length of the second top plate. Figure 1 , which is equivalent to the left side of the second limiting portion 41 extending a certain distance, while the right side of the second limiting portion 41 does not extend. The left side of the second limiting portion 41 is located inside the product and is not easily contacted with other external workpieces. This can prevent the second limiting portion 41 from being squeezed or collided with external objects during production and transportation, resulting in breakage.

[0033] In this embodiment, the first side panel 2 is foldably connected to the bottom panel 1, and the second side panel 3 is foldably connected to the bottom panel 1. The foldable first and second side panels 2 and 3 connected to the bottom panel 1 allow the various components of the assembly to be unfolded, facilitating production and transportation. In other embodiments, the first and second side panels 2, 3, and bottom panel 1 may be integrally formed, forming a three-dimensional, right-angled structure.

[0034] refer to Figure 3 and Figure 4 The folding plate 6 includes a first folding portion 61 and a second folding portion 62 arranged along the length of the first side panel 2. One side of the first folding portion 61 is foldably connected to the second side panel 3, and the other side of the first folding portion 61 is foldably connected to the second folding portion 62. The first folding portion 61 and the second folding portion 62 are both folded and placed below the first top panel 4. Specifically, the folding plate 6 is divided into a first folding portion 61 and a second folding portion 62 that can be folded in sequence. The first folding portion 61 is folded between the second top panel 5 so that the first folding portion 61 and the second folding portion 62 are placed in the protective space. The second folding portion 62 is folded between the first folding portion 61 so that the second folding portion 62 can be closer to the inside of the frame of the photovoltaic module to prevent it from loosening.

[0035] In this embodiment, the dimension of the folding plate 6 along the length direction of the first side plate 2 is greater than the length of the second top plate 5 in the same direction. Figure 2 The length q is greater than the length f, making it difficult for the folded flap 6 to come loose. More preferably, one side of the second folded portion 62 abuts against the inner side of the photovoltaic module frame, with the second side panel 3 abutting the outer wall of the frame and the second folded portion 62 abutting the interior of the frame, thereby preventing it from coming loose. In other embodiments (not shown), where the product may not have space inside to accommodate the folded portion, the folded portion can be folded and layered between the first top panel 4 and the product surface to prevent the corner protector from disintegrating and coming loose.

[0036] In this embodiment, the first top panel 4 further includes a protective portion 42 and a laminated portion 43. One side of the protective portion 42 is folded and connected to the first side panel 2, the other side of the protective portion 42 is connected to one side of the laminated portion 43, and the other side of the laminated portion 43 is connected to the second limiting portion 41. Specifically, the protective portion 42 can protect the surface of the product close to the protective portion, that is, the top left side of the frame in the figure. The laminated portion 43 and the second top panel 5 together can protect the other side of the same side, that is, the top right side of the frame in the figure, thereby better protecting the product.

[0037] In this embodiment, the length of the second top plate 5 along the direction from the second top plate 5 to the folding plate 6 is greater than the length of the stacking portion 43 in this direction, so that the second top plate 5 can effectively cover the folding plate 6 and leave a gap in this direction. There is a certain amount of room for movement in the stacking plate to prevent tearing during assembly.

[0038] Example 2

[0039] This embodiment is similar to embodiment 1. Figure 2 and Figure 3 The difference is that in this embodiment, an anti-collision notch 7 is provided at the junction of the bottom plate 1, the first side plate 2 and the second side plate 3, that is, the anti-collision notch 7 is provided at the top corner formed by the packaging corner guard, which can prevent the first side plate 2 and the second side plate 3 from being squeezed and collided with each other at this point, causing deformation, and prevent the packaging corner guard from disintegrating and loosening.

[0040] Example 3

[0041] refer to Figure 2 This embodiment discloses a packaging corner protector blank, which is used to fold to form the above-mentioned packaging corner protector, including a bottom panel 1, a first side panel 2, a second side panel 3, a first top panel 4, a second top panel 5, and a folding panel 6. The bottom panel 1 has two adjacent sides, which form an L-shaped structure and respectively connect the first side panel 2 and the second side panel 3. The side of the first side panel 2 away from the bottom panel 1 is connected to the first top panel 4, the side of the second side panel 3 away from the bottom panel 1 is connected to the second top panel 5, and the side of the second top panel 5 away from the second side panel 3 is connected to the folding panel 6. The dimension of the second top panel 5 along the length direction of the first side panel 2 is greater than the dimension of the first top panel 4 in this direction. A second limiting portion 41 is provided on the side of the first top panel 4 away from the first side panel 2. The dimension of the second limiting portion 41 along the length direction of the first side panel 2 is greater than the dimension of the second top panel 5 in this direction. In this solution, the above-mentioned packaging corner protector blank is used to fold to form the packaging corner protector, preventing it from loosening and disintegrating during use.

[0042] Specifically, the packaging corner protector blank can be cut from a single piece of cardboard, with pre-extrusion creases formed in various areas of the cardboard to divide the cardboard into distinct foldable sections for subsequent folding. Preferably, a collision-proof notch 7 is provided at the junction of the base panel 1, first side panel 2, and second side panel 3. The collision-proof notch 7 can be rectangular to facilitate cutting. The presence of the collision-proof notch 7 prevents the first side panel 2 and second side panel 3 from collided with each other at the junction after folding, making folding easier.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
