Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0041] In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features.
[0042] The specific embodiments are described with reference to Figures 1 to 4 The present application provides a foldable paper pulp molded buckle structure 100, which is in a strip shape and comprises a main body 10, a first foldable edge 20 and a second foldable edge 30 connected to both ends of the main body 10 and foldable relative to the main body 10.
[0043] The main body 10, the first foldable edge 20 and the second foldable edge 30 in the embodiment are all molded by paper pulp material. Preferably, the main body 10, the first foldable edge 20 and the second foldable edge 30 in the embodiment are integrally formed.
[0044] Preferably, the main body 10, the first foldable edge 20 and the second foldable edge 30 in the embodiment are all provided with clamping blocks 60, as shown in Figure 5 The middle of the clamping block 60 is provided with a clamping groove 61. The clamping groove 61 of the clamping block 60 is used to clamp the side edge of the notebook computer.
[0045] It can be understood that the foldable paper pulp molded buckle structure 100 of the present application is not limited to clamping the side edge of the notebook computer as the inner packaging of the notebook computer, but can also be used as the inner packaging of electronic products such as tablets, mobile phones and other products.
[0046] At least one of the first foldable edge 20 and the second foldable edge 30 of the paper pulp molded buckle structure 100 of the present application is connected by a hole column structure 40 after being folded. As Figure 1As shown in FIG. 1, the first folding edge 20 and the second folding edge 30 are in a long strip shape before being folded relative to the main body 10, Figure 2 As shown in FIG. 2, the first folding edge 20 and the second folding edge 30 are folded 90 degrees relative to the main body 10 to form a U-shaped structure. In other embodiments, the first folding edge 20 and the second folding edge 30 can be folded at various angles, such as 70 degrees, 100 degrees, etc. In this embodiment, the main body 10 is attached to the short side or the long side of the notebook computer, and the first folding edge 20 and the second folding edge 30 of the U-shaped structure are clamped between the upper and lower adjacent sides or the left and right adjacent sides of the notebook computer, thereby providing cushioning protection for the notebook computer.
[0047] The hole-column structure 40 in this embodiment is located at the position where the first folding edge 20 and / or the second folding edge 30 is in close contact with the main body 10 after being folded. The hole-column structure 40 uses a hole and a column in a plug-in fit, and the column has a size larger than the hole after being inserted into the hole to achieve an interference fit. This hole-column structure 40 is equivalent to an embedded expansion fit, which can firmly clamp the first folding edge 20 and / or the second folding edge 30 on the main body 10 to prevent loosening. In the prior art, the packaging and folding of the notebook computer does not have a hole-column structure for embedded fit, so it is easy to come off and cause secondary rework.
[0048] Specifically, the end of the main body 10 of the buckle structure 100 in this embodiment is provided with a blocking wall 11 protruding from the surface of the main body. As shown in the figure, both ends of the main body 10 in this embodiment are provided with blocking walls 11, which are vertically protruding from the surface of the main body 10. The blocking wall 11 has two functions: one is to limit the folding angle of the first folding edge 20 and the second folding edge 30 relative to the main body 10, such as not being able to fold inward any more after being folded 90 degrees in this embodiment, and the other is to be in close contact with the first folding edge 20 and the second folding edge 30 for clamping.
[0049] As an implementation manner, as shown in Figure 3 The hole-column structure 40 in this embodiment includes a buckling hole 41, which is formed in the blocking wall 11, and a buckling boss 42, which is arranged on the first folding edge 20 adjacent to the blocking wall 11. In this embodiment, the buckling boss 42 is protruding from the surface of the first folding edge 20 and adjacent to the blocking wall 11 of the main body 10, and the side wall of the blocking wall 11 facing the buckling boss 42 is provided with the buckling hole 41. In this way, when the first folding edge 20 is folded towards the main body 10, as shown in Figure 2 the buckling boss 42 can be pressed into the buckling hole 41 to achieve buckling in interference fit with the buckling hole 41.
[0050] In the process of folding the long strip-shaped buckle structure 100 into a U shape, the buckle boss 42 is pressed against the back of the first folding edge 20 and pressed towards the buckling buckle 41 of the blocking wall 11 until the buckle boss 42 is inserted into the buckling hole 41 of the blocking wall 11 of the main body 10, and the buckle boss 42 is tightly clamped in the buckling hole 41 by the interference fit of the buckle boss 42 and the buckling hole 41. In this embodiment, the outer diameter of the buckle boss 42 is larger than the hole diameter of the buckling hole 41, so that when the buckle boss 42 is embedded in the buckling hole 41, the two are in an interference fit, and due to the rough characteristics of the pulp material, the contact surface of the buckle boss 42 and the buckling hole 41 is rough, and the buckle boss 42 is larger than the buckling hole 41. The effect of the two superimposed makes the friction between the buckle boss 42 and the buckling hole 41 very large, which can tightly clamp the first folding edge 20 after folding on the main body 10 and will not be separated, avoiding the defect that the clamping is easy to be separated relative to the prior art.
[0051] Preferably, the first folding edge 20, the second folding edge 30 and the main body 10 are provided with a hole column structure 40 for folding and clamping.
[0052] The buckle boss 42 and the buckling buckle 41 in the utility model are structures that do not exist in the prior art.
[0053] As a way, the buckling hole 41 is a blind hole that can be broken under pressure.
[0054] The blind hole type buckling hole 41 is integrally formed on the blocking wall 11 of the main body 10, which can be designed as follows on the corresponding pulp product forming suction mold:
[0055] In the position of the blocking wall forming groove 201 on the pulp suction mold 200, the side wall of the blocking wall forming groove 201 is made into an inner concave groove 202, and the convex block structure 203 is arranged in the middle of the groove 202. The convex block structure 203 is close to the bottom of the blocking wall forming groove 201 Figure 6 The thickness of the bottom of the blocking wall forming groove 201 in the above is thin, and the thickness of the other three sides is thicker than the bottom, so that the product after forming, the buckling hole 41 on the blocking wall 11 is a blind hole with thin upper part and thick bottom. The thin upper part is beneficial to break the blind hole by pressing and make the buckle boss 42 inserted into the buckling hole 41. The design method makes height difference of suction position through the groove 202, reduces the amount of pulp hanging, and makes the pulp accumulated in the groove 202 in the suction process, thereby greatly reducing the amount of overflow.
[0056] As another way, as shown in Figure 3 The buckling hole 41 of the embodiment is a through hole.
[0057] Preferably, as shown in Figure 3As shown, the fastening boss 42 in this embodiment is provided with a guide slope 421. The guide slope 421 is provided so that the fastening boss 42 of the first folded edge 20 can be smoothly inserted into the fastening hole 41 during the folding process.
[0058] Preferably, such as Figure 4 and Figure 5 As shown, the first folded edge 20 and the second folded edge 30 are provided with a slot 50 on the side adjacent to the baffle wall 11, and a protrusion 111 is provided on the top of the baffle wall 11, which can be engaged with the slot 50. That is, when the first folded edge 20 and the second folded edge 30 are bent closer to the main body 10, in addition to the engagement and fixation by the hole column structure 40, they can also be engaged with the slot 50 by the protrusion 111, thereby playing a double engagement and fixation role and improving the fixation effect after folding.
[0059] Preferably, in this embodiment, a reinforcing rib 12 is further connected between the baffle 11 of the main body 10 and the clamping block 60 of the main body 11. For example... Figure 1 and Figure 2 As shown, the reinforcing ribs 12 between the baffle 11 and the clamping block 60 can enhance the strength of the main body 10 and the baffle 11.
[0060] Preferably, such as Figure 7 As shown, the clamping block 60 has a reinforced cavity 62 recessed at the bottom of the clamping groove 61. The reinforced cavity 62 enhances the strength of the bottom of the clamping groove 61, thus providing better support for the object. Furthermore, the cavity wall of the reinforced cavity 62 is also provided with reinforcing ribs 63 to further enhance the structural strength.
[0061] The above description is merely an example to clearly illustrate the present utility model and is not intended to limit the patent scope of the present utility model. It is impossible to exhaustively list all the embodiments here.
