Abstract
Description
Technical Field
[0001] This application relates to the field of EPE packaging technology, and more particularly to an EPE packaging component with a moisture-proof interlayer. Background Technology
[0002] EPE (Expanded Polyethylene) foam, due to its excellent moisture-proof properties, is widely used for packaging moisture-sensitive items such as electronic products, precision instruments, and household appliances. EPE foam's excellent moisture-proof performance stems from its closed-cell foam structure, containing numerous independent air bubbles. These bubble layers effectively prevent water molecule penetration, thus preventing humid air from corroding the packaged items. This moisture-proof property allows EPE foam to keep packaged items dry even in humid environments. While the elasticity of EPE foam can make installation somewhat inconvenient, designing EPE packaging components can easily facilitate the packaging of electronic products with EPE foam.
[0003] Existing technology, patent document CN220465925U, discloses an EPE film positioning and packaging device. This device uses a clamping assembly, with a first baffle and a second baffle providing support and limiting for the clamping assembly. When clamping the EPE film, the clamping plates are pulled outwards, inserting the EPE film from top to bottom between the two sets of clamping plates. Telescopic springs are installed at the front and rear ends of the two sets of clamping plates, providing support at these ends. After the EPE film is inserted, the telescopic springs are compressed, naturally squeezing the EPE film outwards, thereby applying pressure to the front and rear ends of the EPE film and clamping and fixing it. Furthermore, when the EPE film is pulled, the two sets of clamping plates can rotate via a pivot, allowing the clamped and fixed EPE film to adjust its angle according to the direction of force, thus maintaining a constant tension in the EPE film.
[0004] Although the existing technical solutions mentioned above can achieve the adjustment of the angle of the clamped EPE film according to the direction of force through the clamping component, they still have the following drawbacks: the existing technology is an auxiliary EPE packaging, and the packaging process requires manual operation in conjunction with the equipment, which results in many packaging steps and low packaging efficiency.
[0005] In view of this, we propose an EPE packaging assembly with a moisture-proof interlayer. Utility Model Content
[0006] Technical problems to be solved
[0007] This utility model solves the problem of numerous packaging steps and low packaging efficiency mentioned in the background art through its design.
[0008] An EPE packaging assembly with a moisture-proof interlayer includes an EPE base;
[0009] EPE cover frame, wherein the EPE cover frame is inserted into the middle of the EPE base;
[0010] A moisture-proof structure includes connecting grooves at both ends of an EPE cover frame. Multiple moisture-proof clamps are installed inside the connecting grooves. Pressing plates are fixedly connected to the outer ends of the moisture-proof clamps at both ends. Limiting frames abut against the inner ends of the pressing plates. The limiting frames are glued and fixed to both ends of the EPE base. The moisture-proof clamps at the outer ends are slidably connected to the limiting frames and are inserted into the connecting grooves. The moisture-proof clamps in the middle are fixedly connected to the inner wall of the EPE cover frame. The multiple moisture-proof clamps abut against each other.
[0011] The EPE base and EPE cover frame are equipped with reinforcement structures.
[0012] Preferably, the moisture-proof structure includes multiple positioning grooves formed on the bottom surface of the two moisture-proof clamps at the outer end, and a positioning block is engaged in the two positioning grooves. The positioning block is connected and fixed to the limiting frame.
[0013] By adopting the above technical solution, the design of the EPE base and EPE cover frame enables simple and quick packaging of electronic devices, avoiding the problem of packaging with the equipment required by existing technologies. This allows the packaging process to be completed quickly and easily. Furthermore, with the moisture-proof structure design, after the EPE base and EPE cover frame are inserted, pushing the push plate causes the outer moisture-proof clips to insert into the connecting slots at both ends of the EPE cover frame. At this time, multiple moisture-proof clips abut against each other. After the outer moisture-proof clips move, their positioning slots also engage with the positioning blocks inside the limiting frame. This achieves initial stability of the connection between the EPE base and EPE cover frame. The moisture-proof clips also ensure that moisture is isolated, keeping the environment where the electronic device is located dry, achieving both ease of use and effective moisture protection.
[0014] Preferably, the reinforcement structure includes a plurality of longitudinal reinforcement grooves formed in the inner wall of the EPE cover frame, wherein a longitudinal reinforcement block is engaged with the interior of the longitudinal reinforcement groove, and the longitudinal reinforcement block is connected and fixed to the EPE base.
[0015] Preferably, the reinforcement structure includes multiple transverse reinforcement grooves formed in the inner wall of the EPE cover frame, and transverse reinforcement blocks are engaged with each other in the transverse reinforcement grooves, with both ends of the transverse reinforcement blocks having a trapezoidal structure.
[0016] By adopting the above technical solution and the design of the reinforcement structure, during the insertion process of the EPE base and the EPE cover frame, the longitudinal reinforcement groove on the EPE cover frame is connected to the longitudinal reinforcement block on the EPE base. This ensures the longitudinal stability of the EPE base and the EPE cover frame and prevents the EPE cover frame from moving up and down. Finally, the transverse reinforcement groove on the EPE cover frame is connected to the transverse reinforcement block on the EPE base, thus ensuring the transverse stability of the EPE base and the EPE cover frame. In addition, the trapezoidal structure design at both ends of the transverse reinforcement block can further increase the stability of the connection between the transverse reinforcement groove and the transverse reinforcement block. These multiple connections can ensure the stability of the connection between the EPE base and the EPE cover frame and prevent the packaging components from falling apart during transportation.
[0017] Preferably, multiple buffer blocks are fixedly connected to the inner end face of the EPE base and the EPE cover frame, and slots are provided at both ends of the EPE base.
[0018] By adopting the above technical solution and the design of the buffer block, the problem of reduced protection effect caused by the thin upper and lower walls of the EPE base and EPE cover frame can be avoided. In this way, the protection effect can be guaranteed while saving materials. In addition, the slots opened at both ends of the EPE base can make the electronic equipment securely fixed. Beneficial effects
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0020] 1. The design of this utility model, using an EPE base and an EPE cover frame, enables simple and quick packaging of electronic devices, avoiding the need for additional packaging equipment as required by existing technologies. This simplifies the packaging process and allows for rapid completion of the packaging steps. Furthermore, the moisture-proof structure allows for easy insertion of the outer moisture-proof clamps into the connecting slots at both ends of the EPE cover frame after the EPE base and cover frame are connected. At this point, the multiple moisture-proof clamps engage with each other. As the outer moisture-proof clamps move, their positioning slots engage with the positioning blocks inside the limiting frame, thus achieving initial stability of the connection between the EPE base and cover frame. The moisture-proof clamps also ensure moisture isolation, keeping the environment where the electronic device is located dry, achieving both ease of use and effective moisture protection.
[0021] 2. In this utility model, through the design of the reinforcement structure, during the insertion process of the EPE base and the EPE cover frame, the longitudinal reinforcement groove on the EPE cover frame is connected to the longitudinal reinforcement block on the EPE base. This ensures the longitudinal stability of the EPE base and the EPE cover frame, preventing the EPE cover frame from moving up and down. Finally, the transverse reinforcement groove on the EPE cover frame is connected to the transverse reinforcement block on the EPE base, thus ensuring the transverse stability of the EPE base and the EPE cover frame. In addition, the trapezoidal structure design at both ends of the transverse reinforcement block can further increase the stability of the connection between the transverse reinforcement groove and the transverse reinforcement block. These multiple connections ensure the stability of the connection between the EPE base and the EPE cover frame, preventing the packaging components from falling apart during transportation.

[0029] The present application will be further described in detail below with reference to the accompanying drawings. Example

[0031] EPE cover frame 2, EPE cover frame 2 is inserted into the middle of EPE base 1;
[0032] Moisture-proof structure 3 includes connecting grooves 301 at both ends of the EPE cover frame 2. Multiple moisture-proof clamps 302 are provided inside the connecting grooves 301. Pressing plates 303 are fixedly connected to the outer ends of the moisture-proof clamps 302 at both ends. Limiting frames 304 are attached to the inner ends of the pressing plates 303. The limiting frames 304 are glued and fixed to both ends of the EPE base 1. The moisture-proof clamps 302 at the outer ends are slidably connected to the limiting frames 304. The moisture-proof clamps 302 at the outer ends are inserted into the connecting grooves 301. The moisture-proof clamps 302 in the middle are fixedly connected to the inner wall of the EPE cover frame 2. Multiple moisture-proof clamps 302 are attached to each other.
[0033] The EPE base 1 and the EPE cover frame 2 are provided with a reinforcing structure 4.
[0034] The moisture-proof structure 3 includes multiple positioning grooves 305 on the bottom surface of the two moisture-proof clamps 302 at the outer end. A positioning block 306 is engaged in the two positioning grooves 305, and the positioning block 306 is connected and fixed to the limiting frame 304.
[0035] In this embodiment, the design of the EPE base 1 and the EPE cover frame 2 enables simple and quick packaging of electronic devices, avoiding the problem of packaging with the equipment required in existing technologies. This allows the packaging process to be completed quickly and easily. Furthermore, the design of the moisture-proof structure 3 allows the outer moisture-proof clamps 302 to be inserted into the connecting grooves 301 at both ends of the EPE cover frame 2 after the EPE base 1 and EPE cover frame 2 are connected. At this time, the multiple moisture-proof clamps 302 engage with each other. After the outer moisture-proof clamps 302 move, their positioning grooves 305 engage with the positioning blocks 306 inside the limiting frame 304. This achieves initial stability of the connection between the EPE base 1 and the EPE cover frame 2. The moisture-proof clamps 302 also ensure the isolation of moisture, keeping the environment where the electronic device is located dry, achieving both ease of use and effective moisture protection. Example
[0036] Reference Figure 2 , Figure 3 and Figure 4In the second embodiment of this utility model, the reinforcement structure 4 includes a plurality of longitudinal reinforcement grooves 401 opened on the inner wall of the EPE cover frame 2. A longitudinal reinforcement block 402 is snapped into the interior of the longitudinal reinforcement groove 401, and the longitudinal reinforcement block 402 is connected and fixed to the EPE base 1.
[0037] The reinforcement structure 4 includes multiple transverse reinforcement grooves 403 opened on the inner wall of the EPE cover frame 2. Transverse reinforcement blocks 404 are snapped into the transverse reinforcement grooves 403. The two ends of the transverse reinforcement blocks 404 are trapezoidal structures.
[0038] Multiple buffer blocks 5 are fixedly connected to the inner end faces of the EPE base 1 and the EPE cover frame 2, and slots 6 are opened at both ends of the EPE base 1.
[0039] In this embodiment, the design of the reinforcement structure 4 allows the longitudinal reinforcement groove 401 on the EPE cover frame 2 to connect with the longitudinal reinforcement block 402 on the EPE base 1 during the insertion process of the EPE base 1 and the EPE cover frame 2. This ensures the longitudinal stability of the EPE base 1 and the EPE cover frame 2 and prevents the EPE cover frame 2 from moving up and down. Finally, the transverse reinforcement groove 403 on the EPE cover frame 2 connects with the transverse reinforcement block 404 on the EPE base 1, thus ensuring the transverse stability of the EPE base 1 and the EPE cover frame 2. Furthermore, the trapezoidal structure design at both ends of the transverse reinforcement block 404 further increases the stability of the connection between the transverse reinforcement groove 403 and the transverse reinforcement block 404. These multiple connections ensure the stability of the connection between the EPE base 1 and the EPE cover frame 2 and prevent the packaging components from falling apart during transportation.
[0040] The design of the buffer block 5 can avoid the problem of reduced protection effect caused by the thin upper and lower walls of the EPE base 1 and EPE cover frame 2. In this way, the protection effect can be guaranteed while saving materials. In addition, the slots 6 opened at both ends of the EPE base 1 can make the electronic equipment securely fixed.
[0041] The implementation principle of an EPE packaging assembly with a moisture-proof interlayer in this application embodiment is as follows: In the packaging of electronic devices, the two ends of the electronic devices are inserted into the slots 6 at both ends of the EPE base 1, and then the EPE cover frame 2 is covered. After the EPE base 1 and the EPE cover frame 2 are inserted, the push-press plate 303 is pushed to drive the moisture-proof clamps 302 at the outer end to be inserted into the connecting slots 301 at both ends of the EPE cover frame 2. At this time, the multiple moisture-proof clamps 302 abut against each other. After the moisture-proof clamps 302 at the outer end move, the positioning slots 305 on them will also engage with the positioning blocks 306 inside the limiting frame 304. In this way, the initial stability of the connection between the EPE base 1 and the EPE cover frame 2 can be achieved.
[0042] During the insertion process of EPE base 1 and EPE cover frame 2, the longitudinal reinforcing groove 401 on EPE cover frame 2 will connect with the longitudinal reinforcing block 402 on EPE base 1. This ensures the longitudinal stability of EPE base 1 and EPE cover frame 2 and prevents EPE cover frame 2 from moving up and down. Finally, the transverse reinforcing groove 403 on EPE cover frame 2 will connect with the transverse reinforcing block 404 on EPE base 1. This ensures the transverse stability of EPE base 1 and EPE cover frame 2. In addition, the trapezoidal structure design at both ends of transverse reinforcing block 404 can further increase the stability of the connection between transverse reinforcing groove 403 and transverse reinforcing block 404. These multiple connections ensure the stability of the connection between EPE base 1 and EPE cover frame 2 and prevent the packaging components from falling apart during transportation.
