[0035] Currently, the protection of the refrigerator drawer is mainly achieved through the structural design of packaging materials, so that the protection structure can support the refrigerator drawer to prevent the refrigerator drawer from being damaged due to displacement during transportation. However, the existing guard plates of refrigerator drawers are often formed through processes such as cutting and gluing during production, which greatly wastes materials and significantly increases the production cost of materials.

[0036] Based on this, the present utility model proposes a protection plate, aiming to solve the problem that the existing guard plates of refrigerator drawers waste a large amount of materials during production, resulting in a relatively high production cost of materials.

[0037] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, the protection plate 100 includes a plurality of plate segments connected to each other. The plurality of plate segments include at least one trimmed and formed plate segment 1. The trimmed and formed plate segment 1 can be folded in the length direction of the protection plate 100 to protrude and extend a clamping portion 3 in the thickness direction of the protection plate 100 for clamping the refrigerator drawer 200.

[0038] In the technical solution of the present utility model, when cutting the packaging material, the regular-shaped protective plate 100 is first cut out, and then the regular-shaped protective plate 100 is folded to protrude and extend the clamping portion 3 in the thickness direction of the protective plate 100, so as to form the special-shaped protective plate 100, enabling the protective plate 100 to meet the protection requirements of the refrigerator drawer 200. Thus, by providing the trimming and forming plate segment 1, the protective plate 100 can be folded to form the clamping portion 3, so that the special-shaped protective plate 100 can be formed by the regular-shaped protective plate 100. When cutting the packaging material, the cutting thickness of the protective plate 100 can be reduced, greatly reducing the loss during the cutting of the packaging material, thereby solving the problem that the waste of the protective plate of the existing refrigerator drawer 200 is relatively large during production, resulting in a relatively high material production cost.

[0039] It should be noted that, referring to Figure 5 , when cutting the existing packaging material, the clamping portion 3 on the protective plate 100 is usually obtained by direct cutting. The existence of the clamping portion 3 will increase the cutting thickness of the protective plate 100, and only a small part of the increased thickness is used to form the clamping portion 3, and most of the rest is discarded, resulting in relatively serious waste of the packaging material. Therefore, in the present utility model, by providing the trimming and forming plate segment 1, the protective plate 100 can be folded to form the clamping portion 3, so that the special-shaped protective plate 100 can be formed by the regular-shaped protective plate 100. When cutting the packaging material, the cutting thickness of the protective plate 100 can be reduced, greatly reducing the loss during the cutting of the packaging material.

[0040] For the convenience of folding the trimming and forming plate segment 1, in an embodiment of the present utility model, referring to Figure 1 and Figure 2 , the trimming and forming plate segment 1 has a first trimming and forming surface 11 in its thickness direction, and a notch is provided on the first trimming and forming surface 11, so that the trimming and forming plate segment 1 can be folded on one side of the first trimming and forming surface 11. Thus, by providing the notch, the bending trace of the trimming and forming plate segment 1 can be positioned on the protection, which is not only convenient for bending the trimming and forming plate segment 1, but also can avoid the protective plate 100 being squeezed and deformed due to insufficient bending space.

[0041] Furthermore, there are multiple locations for setting the incision. Specifically, in one embodiment of the utility model, the plurality of plate segments include a connecting plate segment 2, the trimmed and formed plate segment 1 includes an end connected to the connecting plate segment 2, and the incision includes a first incision 12 provided at the end. In this way, by setting the first incision 12, the trimmed and formed plate segment 1 can be bent toward a side away from the first trimmed forming surface 11 at the connection between the trimmed and formed plate segment 1 and the connecting plate segment 2, so that the trimmed and formed plate segment 1 can protrude along the thickness direction of the protective plate 100 to form the clamping portion 3. Furthermore, if the first incision 12 is too shallow, the bending space of the trimming and shaping plate segment is small, which may easily cause the protective plate 100 to be squeezed and deformed. Conversely, if the depth of the first incision 12 is too large, the trimming and forming plate segment 1 may be easily broken when bending. For this reason, in the present embodiment, the depth of the first incision 12 is H, and the thickness of the end of the trimming and forming plate segment 1 is D, wherein D / 2≤H≤3D / 4. This can prevent the connection between the trimming and forming plate segment 1 and the connecting plate segment 2 from being broken due to the first incision 12 being too deep, and also ensure that the trimming and forming plate segment 1 has sufficient bending space to prevent the protective plate 100 from being squeezed and deformed due to insufficient bending space.

[0042] Furthermore, the first incision 12 has a first incision side wall 121 and a second incision 13 side wall 122 distributed along the length direction of the protective plate 100, the first incision side wall 121 is located on the side of the second incision 13 side wall 122 facing the connecting plate segment 2, the first incision side wall 121 extends along the thickness direction of the protective plate 100, and the second incision 13 side wall 122 extends obliquely along the thickness direction of the protective plate 100, so that the first incision 12 is gradually expanded from its bottom toward its opening direction, and the first incision side wall 121 is set so that the trimmed and formed plate segment 1 after bending can be flush with the end face of the connecting plate segment 2, and the second incision 13 side wall 122 is set so that the first incision 12 is gradually expanded, so that the trimmed and formed plate segment 1 has sufficient bending space to bend outward to prevent deformation due to the involvement of the trimmed and formed plate segment 1 and the connecting plate segment 2. Of course, in other embodiments, the first cut side wall 121 may also be inclined, etc., and the present invention does not limit this. However, if the first cut side wall 121 is inclined, after the trimmed and formed plate segment 1 is folded, a gap will be formed at the fold, which will affect the strength of the clamping portion 3.

[0043] In another embodiment of the present utility model, the incision further includes a second incision 13 provided in the middle of the trimming and forming plate section 1. The trimming and forming plate section 1 can be folded along the second incision 13. Thus, by providing the second incision 13 in the middle of the trimming and forming plate section 1, the inner folding position of the trimming and forming plate section 1 is positioned in the middle of the trimming and forming plate section 1, so that the trimming and forming plate section 1 can be bent inward, thereby facilitating the folding of the trimming and forming plate section 1 at the second incision 13.

[0044] Furthermore, the second incision 13 has two third incision side walls 131 distributed along the length direction of the protection plate 100. The third incision side walls 131 extend obliquely along the thickness direction of the protection plate 100, so that the second incision 13 is arranged to gradually expand from its bottom to its opening. Thus, by providing the two third incision side walls 131, the second incision 13 is arranged to gradually expand, so that the trimming and forming plate section 1 has sufficient bending space to bend inward, preventing the trimming and forming plate section 1 from being deformed due to extrusion when bending at the second incision 13.

[0045] In an embodiment of the present utility model, the depth of the second incision 13 is L, and the thickness of the trimming and forming plate section 1 is D, where D / 2 ≤ L ≤ 3D / 4. This can not only avoid the connection between the trimming and forming plate section 1 and the connecting plate section 2 being broken due to the second incision 13 being too deep, but also enable the trimming and forming plate section 1 to have sufficient bending space, so as to prevent the protection plate 100 from being deformed due to insufficient bending space.

[0046] In order to enable the trimming and forming plate section 1 to maintain a folded state, in an embodiment of the present utility model, please refer to Figures 1 to 3 , the trimming and forming plate section 1 has a first trimming and forming surface 11 in its thickness direction. A bonding layer is provided on the first trimming and forming surface 11, so that the folded trimming and forming plate section 1 is adhesively bonded and fitted. Thus, by providing the bonding layer, the trimming and forming plate section 1 can be adhesively bonded together after folding, so that the trimming and forming plate section 1 maintains a folded state. It can be understood that the bonding layer can be a tape, glue, etc., as long as it can fix the folded trimming and forming plate section 1 together. The present utility model does not limit this.

[0047] It should be noted that there are various ways to fix the trimming and forming plate section 1. In other embodiments, the trimming and forming plate section 1 can also be fixed by riveting, etc. The present utility model does not limit this.

[0048] In order to enable the trimming and forming plate section 1 to have sufficient bending space, in an embodiment of the present utility model, please refer toFigures 1 to 3 The trimming and forming plate segment 1 has a first trimming and forming surface 11 and a second trimming and forming surface 14 opposite to each other in its thickness direction. The second trimming and forming surface 14 is concave, so that the formed clamping portion 3 is tapered along its protruding direction, so that the second trimming and forming surface 14 can increase the length along the length direction of the protection plate 100, so that when the second trimming and forming surface 14 is bent outward, it has enough bending length to prevent the trimming and forming plate segment 1 from being deformed due to extrusion during folding, thus facilitating the folding of the trimming and forming plate segment 1 to form the clamping portion 3.

[0049] In order to make the thickness of the folded clamping portion 3 meet the requirements of the refrigerator drawer 200, in this embodiment, a plurality of the plate segments include a connecting plate segment 2 connected to the trimming and forming plate segment 1. Before folding, in the thickness direction of the protection plate 100, the trimming and forming plate segment 1 is retracted relative to the connecting plate segment 2, so that the thickness of the trimming and forming plate segment 1 is less than the thickness of the connecting plate segment 2, so as to reduce the thickness of the clamping portion 3 and prevent the clamping portion 3 from being too thick to be inserted into the drawer 200 of the refrigerator, so that the folded clamping portion 3 can meet the requirements of the refrigerator drawer 200.

[0050] In an embodiment of the present invention, a plurality of the trimming and forming plate segments 1 are provided, and the plurality of trimming and forming plate segments 1 are arranged at intervals along the length direction of the protection plate 100. In this way, by providing the trimming and forming plate segments 1, the protection plate 100 can directly form a plurality of the clamping portions 3, so as to avoid forming a plurality of the clamping portions 3 by splicing later, which helps to improve the production efficiency of the protection plate 100.

[0051] There are various materials for the protection plate 100. For example, the material of the protection plate 100 can be EPS foam (polystyrene foam), or EPE foam (polyethylene foam), etc. The present invention does not limit this, but if EPS foam is used for protection, since EPS foam will continuously volatilize odors, the smell will be pungent after the refrigerator door is opened in a long-term closed environment, which extremely affects the use experience. At the same time, the EPS foam protection piece is formed by foaming and is extremely easy to break during use, thus losing its protection function. Therefore, in this embodiment, the material of the protection plate 100 includes polyethylene foam, which can not only avoid the problem of odor generation by EPS foam, but also avoid the problem that the protection plate 100 is easy to break, and enhances the protection strength.

[0052] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
