Description

Technical Field

[0001] The utility model relates to the field of packaging boxes, in particular to a fastening type EPE shock-absorbing packaging structure. Background Art

[0002] In the existing packaging field, EPE (expanded polyethylene) is widely used due to its excellent shock absorption properties and lightweight weight, especially for packaging precision workpieces or fragile items that require shock absorption protection. However, traditional EPE packaging structures often have some problems, such as easy deformation and easy dislocation and separation of joints. These problems may cause damage to the workpiece or packaging failure during transportation and storage.

[0003] To address these issues, some improved EPE packaging structures have emerged on the market, but they are often complex in structure, expensive to manufacture, and in some cases still cannot completely prevent the problem of joint dislocation and falling off. Therefore, it is particularly important to develop a fastening EPE shock-absorbing packaging structure that is simple in structure, low in cost, and can effectively prevent joint dislocation and falling off. Utility Model Content

[0004] The purpose of the present utility model is to provide a fastening type EPE shock-absorbing packaging structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fastening type EPE shock-absorbing packaging structure, comprising an EPE base box, a reserved groove is provided on the top of the EPE base box, an EPE box cover is sleeved on the upper part of the reserved groove, a plastic frame 1 is sleeved and fixed on the inner annular surface of the reserved groove, a plastic frame 2 is fixed on the inner annular surface of the EPE box cover, the EPE box cover is sleeved on the reserved groove, and the plastic frame 2 is sleeved on the plastic frame 1.

[0006] A limiting clamp is provided between the first plastic frame and the second plastic frame.

[0007] Preferably, an EPE partition frame is fixed to the inner wall of the EPE base box, and the EPE partition frame has a grid-like structure.

[0008] Preferably, the reserved groove is an annular groove, and the heights of the reserved groove, the first plastic frame and the second plastic frame are equal.

[0009] Preferably, the limit card includes an embedding groove, a limit plug-in plate, a positioning socket and a rubber support block. The embedding groove is a "convex" shaped groove, and the embedding groove is provided on the outer ring surface of the plastic frame 1. There are two embedding grooves, and the two embedding grooves are symmetrically distributed about the EPE base box. The limit plug-in plate is a "convex" shaped plate, and one end of the limit plug-in plate is inserted into the positioning socket, and the positioning socket is provided on the surface of the plastic frame 2. The rubber support block is fixed between one end of the limit plug-in plate extending into the embedding groove and the embedding groove.

[0010] Preferably, a slope is provided on the top surface of one end of the limiting plug plate.

[0011] Preferably, after the EPE box cover is placed on the reserved groove, a limiting clamp is exposed on the inner side of the groove.

[0012] Preferably, an EPE sealing sheet is fixed to the top surface of the notch, the height of the EPE sealing sheet is equal to the height of the notch, and gaps are reserved between the two sides of the EPE sealing sheet and two parallel side walls of the notch.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The fastened EPE shock-absorbing packaging structure proposed in this utility model forms a rigid, non-deformable frame at the connection between the EPE base box and the EPE lid by placing plastic frames 1 and 2 between them and adding a position-limiting clip between them. This structure significantly enhances the stability of the packaging and avoids the problem of dislocation and detachment at the connection caused by the easily deformable EPE material. The position-limiting clip is cleverly designed, utilizing the elastic deformation of the rubber support block to accommodate the downward movement of plastic frame 2. Once plastic frame 2 is fully encased in plastic frame 1, the rubber support block's rebound forces the position-limiting plate into the positioning socket, achieving a secure connection. This design not only improves the packaging's anti-slip position-limiting capability but also makes disassembly of the EPE lid relatively simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 7 The utility model provides a technical solution: a fastened EPE shock-absorbing packaging structure, comprising an EPE base box 1, an EPE partition frame 13 is fixed to the inner wall of the EPE base box 1, and the EPE partition frame 13 is in a tic-tac-toe grid structure. A reserved groove 3 is provided on the top of the EPE base box 1, and an EPE box cover 2 is sleeved on the top of the reserved groove 3. A plastic frame 1 4 is sleeved and fixed on the inner ring surface of the reserved groove 3, and a plastic frame 2 5 is fixed on the inner ring surface of the EPE box cover 2. After the EPE box cover 2 is sleeved on the reserved groove 3, the plastic frame 2 5 is sleeved on the plastic frame 1 4. The reserved groove 3 is an annular groove, and the heights of the reserved groove 3, the plastic frame 1 4 and the plastic frame 2 5 are equal.

[0026] During use, an EPE partition frame 13 that matches the shape of the workpiece to be stored is installed inside the EPE base box 1 according to actual needs, so as to isolate multiple workpieces stored inside the EPE base box 1 from each other; after the EPE box cover 2 is put on the top of the EPE base box 1, the plastic frame 2 5 is put on the plastic frame 1 4, forming a non-deformable frame at the connection between the EPE base box 1 and the EPE box cover 2, thereby avoiding the problem of misalignment and falling off of the EPE base box 1 and the EPE box cover 2 at the installation point due to the easy deformation of the EPE box cover 2 and the EPE base box 1.

[0027] A limit card is provided between the plastic frame 1 4 and the plastic frame 2 5. The limit card includes an embedding groove 8, a limit plugboard 9, a positioning socket 11 and a rubber support block 12. The embedding groove 8 is a "convex" shaped groove. The embedding groove 8 is opened on the outer ring surface of the plastic frame 1 4. There are two embedding grooves 8. The two embedding grooves 8 are symmetrically distributed about the EPE base box 1. The limit plugboard 9 is a "convex" shaped plate. One end of the limit plugboard 9 is plugged into the positioning socket 11. The positioning socket 11 is opened at On the surface of the plastic frame 5, the rubber support block 12 is fixed between one end of the limiting plug plate 9 extending into the embedding groove 8 and the embedding groove 8. A slope 10 is provided on the top surface of one end of the limiting plug plate 9. After the EPE box cover 2 is sleeved on the reserved groove 3, the limiting card is exposed on the inner side of the notch 6; an EPE sealing sheet 7 is fixed on the top surface of the notch 6, and the height of the EPE sealing sheet 7 is equal to the height of the notch 6. Gaps are reserved between the two sides of the EPE sealing sheet 7 and the two parallel side walls of the notch 6.

[0028] When in use, in order to enhance the anti-dropping limit of the EPE box cover 2 after it is set on the EPE base box 1, a limit card is added. When the EPE box cover 2 is set on the top of the EPE base box 1, the plastic frame 2 5 slides down along the plastic frame 1 4. The bottom end of the plastic frame 2 5 pushes the limit plug-in plate 9 along the inclined surface 10 and retracts into the embedded groove 8. At this time, the limit plug-in plate 9 squeezes the rubber support block 12 to produce elastic deformation. Until the plastic frame 2 5 is completely set on the plastic frame 1 4, the positioning socket 11 and the limit plug-in plate 9 correspond, and the rubber support block 12 rebounds and pushes the limit plug-in plate 9. The positioning plug plate 9 is reset, and one end of the limit plug plate 9 is inserted into the positioning socket 11 to connect the plastic frame 1 4 and the plastic frame 2 5, so as to prevent the EPE box cover 2 from falling off the EPE base box 1; the reason for reserving the notch 6 is that when the EPE box cover 2 is disassembled, the finger is inserted into the notch 6, pushing the limit plug plate 9, and after the limit plug plate 9 is pushed out of the positioning socket 11, the plastic frame 1 4 is lifted up to remove the EPE box cover 2 from the top of the EPE base box 1, and an EPE sealing piece 7 is added on the inner side of the notch 6 to block the notch 6.

[0029] The specific process of use is as follows:

[0030] Structural Assembly and Configuration: First, install appropriate EPE dividers 13 inside the EPE base box 1, based on the shape and size of the workpieces to be stored. These dividers 13 are grid-like structures, used to divide the interior of the EPE base box 1 into multiple smaller areas for storing and isolating multiple workpieces. A reserved groove 3 is provided at the top of the EPE base box 1, with a plastic frame 1 4 fixed to its inner annular surface. A plastic frame 2 5 is fixed to the inner annular surface of the EPE lid 2.

[0031] Closing and initial fixation: Put the EPE box cover 2 on the top of the EPE base box 1, and slide the plastic frame 2 5 along the plastic frame 1 4 and put it on it. Since the reserved groove 3, plastic frame 1 4 and plastic frame 2 5 are of equal height and all have an annular structure, they can fit tightly together to form a preliminary fixation.

[0032] The function of the limiting card: In order to further ensure that the EPE box cover 2 will not fall off the EPE base box 1, a limiting card is added. The limiting card consists of an embedding groove 8, a limiting plug plate 9, a positioning socket 11 and a rubber support block 12. When the EPE box cover 2 is mounted on the EPE base box 1, the bottom end of the plastic frame 2 5 will slide along the inclined surface 10 on the limiting plug plate 9, thereby pushing the limiting plug plate 9 to retract into the embedding groove 8. At this time, the rubber support block 12 is squeezed and elastically deformed. When the plastic frame 2 5 is completely mounted on the plastic frame 1 4, the positioning socket 11 corresponds to the limiting plug plate 9. At this time, the rubber support block 12 rebounds, pushing the limiting plug plate 9 to reset, so that one end of it is inserted into the positioning socket 11, thereby achieving a firm connection between the plastic frame 1 4 and the plastic frame 2 5.

[0033] Disassembly process: To disassemble the EPE box cover 2, you need to first operate through the notch 6. The notch 6 is located at a certain position on the EPE box cover 2, and an EPE sealing sheet 7 is fixed on its top surface to block the notch 6. The height of the EPE sealing sheet 7 is equal to the height of the notch 6, and there is a gap between its two sides and the two parallel side walls of the notch 6. You can insert your fingers into the notch 6 and push the limit plate 9 to push it out of the positioning socket 11. Then, lift up the plastic frame 2 5 (that is, the part of the EPE box cover 2) to remove the EPE box cover 2 from the top of the EPE base box 1.

[0034] Overall Function and Effect: This tight, shock-absorbing EPE packaging structure, through the coordinated use of components such as the EPE base box 1, EPE divider 13, EPE cover 2, and position-limiting clips, tightly stores and secures workpieces. Furthermore, thanks to its use of EPE (expanded polyethylene) material, the packaging structure also offers excellent shock-absorbing properties, effectively protecting workpieces from external shock and vibration.
