Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, specifically to an integrated corrugated support plate. Background Technology
[0002] In the packaging and shipping of plastic exterior parts, especially automotive plastic parts, their exteriors are generally polished and painted. Therefore, extra care must be taken to prevent scratches on their surfaces during transportation. When shipping in cardboard boxes, in order to prevent the plastic parts from shaking inside and rubbing against the outer surface, resulting in defective products, the plastic parts need to be secured.
[0003] There are many ways to secure components, with foam padding being a common method. However, this method has drawbacks, including high wear and tear (the components are discarded after a single use), and the risk of scratches on the paint surface of high-end plastic parts like car bumpers due to friction between the foam padding and the bumper during transport. Therefore, designing a packaging product that is reusable and effectively secures high-end plastic parts (such as car front bumpers) during transport is a problem that urgently needs to be solved by those in the field. Furthermore, this packaging product needs to be compatible with the outer carton. Utility Model Content
[0004] The purpose of this utility model is to design a packaging product with reusable value and effective fixation of high-end plastic parts during transportation. This utility model provides an integrated corrugated support plate.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0006] An integrated corrugated support board includes corrugated cardboard, wherein both opposite sides of the corrugated cardboard can be folded to form a box-shaped support unit, and the box-shaped support unit located at the center of the corrugated cardboard can be folded to form a positioning unit that supports plastic parts.
[0007] The positioning unit and the box-shaped support unit can be flattened on the same plane as the corrugated cardboard.
[0008] Furthermore, the box-shaped support unit includes a main cardboard connected to the corrugated cardboard with creases at the connection point and side cardboards connected to the two sides of the main cardboard with creases at the connection point. The side of the main cardboard away from the corrugated cardboard is connected to a top cardboard with creases at the connection point. The side of the top cardboard away from the main cardboard is connected to a back cardboard with creases at the connection point.
[0009] Furthermore, the two side panels have snap fasteners on their edges away from the main panel, and the back panel is configured for the snap fasteners to pass through snap-in holes.
[0010] Furthermore, the positioning unit includes a positioning groove at the connection between the main cardboard and the corrugated cardboard. Two positioning cardboards are connected by folds in the positioning groove. The two positioning cardboards are also connected to each other, and folds are also constructed at the connection point. Side positioning paper wings are connected by folds on both sides of the positioning cardboard.
[0011] Furthermore, it also includes positioning holes that extend through the thickness of the corrugated cardboard.
[0012] Furthermore, the number of positioning units and their relative positions on the corrugated cardboard are determined by the specific structure of the plastic part.
[0013] Furthermore, the number of positioning holes and their relative positions on the corrugated cardboard are determined by the specific structure of the plastic part.
[0014] Furthermore, the top of the box-shaped support unit can be used to support the corrugated cardboard stacked above it.
[0015] The beneficial effects of this utility model are as follows:
[0016] This utility model defines one direction of the plastic part between two main cardboard sections, and two positioning units on the other side define the displacement of the plastic part in the other direction. In combination with the structure of this application being installed in a packaging carton, the plastic part is relatively fixed relative to this structure, and this structure is relatively fixed relative to the packaging carton. Thus, there is no problem of friction caused by relative shaking between the plastic part and the carton, which would lead to damage to the surface paint.
[0017] This invention features snap fasteners on the edges of the two side cardboards away from the main cardboard, and the back cardboard structure is designed for the snap fasteners to pass through the insertion holes. The method of inserting the snap fasteners into the insertion holes allows the box support unit to be formed and prevents it from collapsing. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0022] This embodiment provides an integrated corrugated support plate, mainly used to design a packaging product with reusable value and effective fixation of high-end plastic parts during transportation. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-2 Please provide a detailed explanation: Example
[0023] A one-piece corrugated support board includes corrugated cardboard 1. The corrugated cardboard 1 used in this application is a multi-layered adhesive with high mechanical strength, capable of withstanding collisions and drops during handling, and is commonly used in the packaging industry (existing technology). Both opposite sides of the corrugated cardboard 1 can be folded to form box-shaped support units 2. The box-shaped support units 2, located at the center of the corrugated cardboard 1, can also be folded to form positioning units 3 that support plastic parts. (See also...) Figure 1 and Figure 2 The box-shaped support unit 2 includes a main cardboard 21 connected to the corrugated cardboard 1 with creases at the connection point, and side cardboard 22 connected to the two sides of the main cardboard 21 with creases at the connection point. A top cardboard 23 is connected to the side of the main cardboard 21 away from the corrugated cardboard 1 with creases at the connection point. A back cardboard 24 is connected to the side of the top cardboard 23 away from the main cardboard 21 with creases at the connection point. The above structure is arranged according to... Figures 2 to 1 By folding it in the form of a box, we can obtain box-shaped support unit 2. Please refer to [link / reference] for details. Figure 1 When this structure is placed in a packaging box, its four ends can abut against the four side walls of the packaging box (specifically, the two ends of the corrugated cardboard 1 and the two end walls of the box-shaped support unit 2), ensuring its relative stability with the cardboard box. Secondly, as... Figure 1 The positioning unit 3 includes a positioning groove 31 at the connection between the main cardboard 21 and the corrugated cardboard 1. Two positioning cardboards 32 are connected by folds within the positioning groove 31. The two positioning cardboards 32 are also connected to each other, and folds are also constructed at the connection point. Side positioning paper wings 33 are folded to both sides of each positioning cardboard 32. When the main cardboard 21 is positioned in the manner described above... Figure 1 After being folded in the middle form, the positioning slot 31 can be folded into... Figure 1 In the pattern shown, folding the positioning cardboard 32 to the side positioning wing 33 can construct a positioning protrusion. The key point of this application is that: generally, car bumpers or large exterior plastic parts are constructed with studs for assembly and latches to limit their own position. Therefore, by simply designing the position of the box support unit and the position of the positioning unit 3 according to the specific size of the product, the limitation can be achieved. That is to say, the two main cardboard 21 limit one direction of the plastic part, located in... Figure 1The two positioning units 3 on one side limit the displacement of the plastic part in another direction. In combination with the structure of this application being installed in a packaging carton, the plastic part is relatively fixed relative to this structure, and this structure is relatively fixed relative to the packaging carton. Thus, there is no problem of friction caused by relative shaking between the plastic part and the carton, which would lead to damage to the surface paint.
[0024] Furthermore, to ensure that the structure of this application can be applied to other batches of products after use, the positioning unit 3 and the box-shaped support unit 2 can be flattened onto the same plane as the corrugated cardboard 1, as shown in the following flattened state: Figure 2 As shown in the image. Example
[0025] Based on Embodiment 1, this embodiment adds the following technical solution: the two side cardboards 22 have snap fasteners 4 on their edges away from the main cardboard 21, and the back paper 24 is designed for the snap fasteners 4 to pass through the snap-in holes 5. The method of inserting the snap fasteners into the holes 5 allows the box support unit to be formed and prevents it from collapsing.
[0026] In this embodiment, the plastic part is more stably fixed on the corrugated cardboard 1, and a positioning hole 6 is also included that penetrates the thickness of the corrugated cardboard 1. The position and number of the positioning hole 6 on the corrugated cardboard 1 are determined by the specific structure of the plastic part.
[0027] The top of the box unit is designed to support the corrugated cardboard 1 stacked above it, so that multiple plastic items can be placed in a single carton.
