Abstract
Description
Technical Field
[0001] This application relates to the field of antistatic EPE technology, and more particularly to an antistatic EPE for the protection of electronic equipment. Background Technology
[0002] EPE (Expanded Polyethylene) foam, also known as polyethylene foam, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also has excellent chemical resistance. When used in the packaging of electronic devices, EPE foam requires anti-static treatment to prevent static electricity from damaging the electronic equipment.
[0003] The prior art patent document CN216270428U discloses an antistatic foam pad for electronic products. This device, through the cooperation of a second locking block and a second locking slot, enables the antistatic pad and EPE pearl cotton to be spliced and installed together. This allows for timely replacement of the antistatic pad when it is damaged, eliminating the need to replace the EPE pearl cotton and reducing the cost associated with damage to the foam pad itself. Furthermore, through the cooperation of a first locking block, a mounting plate, and a mounting rod, four sets of foam pads can be combined into a single foam pad when installed inside a mounting frame. This design allows for the replacement of damaged foam pads with new ones, avoiding the need to replace the entire foam pad when damaged, thus reducing production and usage costs. Simultaneously, the mounting plate and mounting rod ensure greater stability when splicing the four sets of foam pads, preventing misalignment.
[0004] Although the existing technical solutions mentioned above can avoid the problem of having to replace all foam pads when they are damaged by using the second card block and the second card slot, they still have the following defects: When connecting the antistatic pad and EPE pearl cotton, the connection between the antistatic pad and EPE pearl cotton is not tight due to the large proximity of the two connection points, resulting in poor protective and antistatic effects.
[0005] In view of this, we propose an anti-static EPE for the protection of electronic equipment. Utility Model Content
[0006] Technical problems to be solved
[0007] This invention solves the problems mentioned in the background art by setting up an anti-static protection structure.
[0008] Technical solution
[0009] An antistatic EPE for protecting electronic equipment includes an antistatic protection structure. The antistatic protection structure includes an antistatic layer, on which a pearl cotton layer is abutted. Multiple fixing grooves are formed on the inner end faces of both the pearl cotton layer and the antistatic layer. Connecting posts are inserted into two of the fixing grooves. Slots are formed at both ends of the connecting posts. Insert rods are inserted into the slots. Connecting rods are fixed to the multiple insert rods. The insert rods have an L-shaped structure, and the two ends of the connecting posts have an arc-shaped structure.
[0010] By adopting the above technical solution, after the antistatic layer or pearl cotton layer of the antistatic protection structure is damaged, the plug on the connecting rod can be inserted into the corresponding slot of the connecting post according to the corresponding needs. This increases the connection strength between the connecting post and the undamaged structure, allowing the antistatic layer and pearl cotton layer to be directly pulled apart. The damaged structure can then be removed and secured with the intact structure. Replacement is convenient, and the multi-point connection method provides a more stable connection. This design avoids the problem of large-area connection gaps caused by the concentrated connection structure in existing technologies, ensuring the tight connection between the antistatic layer and the pearl cotton layer, thus guaranteeing the protective and antistatic effects.
[0011] Preferably, a limiting frame is slidably connected to the insertion rod and the insertion rod, and a fixing strip is fixedly connected to the limiting frame.
[0012] Preferably, multiple positioning rings are connected and fixed on the fixing strip. The fixing strip, the limiting frame and the positioning rings located at the top and bottom are respectively connected and fixed to the antistatic layer and the pearl cotton layer. Corresponding holes and grooves are opened inside the antistatic layer and the pearl cotton layer.
[0013] Preferably, pressing blocks are fixedly connected to both ends of the connecting rod, and the pressing blocks slide in fit with the internal grooves of the antistatic layer and the pearl cotton layer.
[0014] Preferably, a pressing rod is abutted on the pressing block, and the pressing rod is inserted into the groove on the outer wall of the antistatic layer and the pearl cotton layer.
[0015] By adopting the above technical solution, during the process of the pressing rod abutting against and driving the connecting rod and the insertion rod on the pressing block to move, the limiting frame can slide and limit them. On the one hand, it ensures that the connecting rod drives the insertion rod to move smoothly, and on the other hand, it ensures that the insertion rod can be accurately inserted into the slot. The fixing strip on the limiting frame, together with the positioning ring, can make the connection between the limiting frame and the antistatic layer and the pearl cotton layer more stable and prevent displacement. Beneficial effects
[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0017] 1. In this utility model, after the antistatic layer or pearl cotton layer of the antistatic protection structure is damaged, the plug on the connecting rod can be inserted into the corresponding slot of the connecting post according to the corresponding needs. This increases the connection strength between the connecting post and the undamaged structure, allowing the antistatic layer and pearl cotton layer to be directly pulled apart. The damaged structure can then be removed and secured with the intact structure. Replacement is convenient, and the multi-point connection method provides a more stable connection. This design avoids the problem of large-area connection voids caused by the concentrated connection structure in existing technologies, ensuring the tight connection between the antistatic layer and the pearl cotton layer, thus guaranteeing the protective and antistatic effects.
[0018] 2. In this utility model, during the process of the pressing rod abutting against and driving the connecting rod and the insertion rod on the pressing block to move, the limiting frame can slide and limit them. On the one hand, it ensures that the connecting rod drives the insertion rod to move smoothly, and on the other hand, it ensures that the insertion rod can be accurately inserted into the slot. The fixing strip on the limiting frame, together with the positioning ring, can make the connection between the limiting frame and the antistatic layer and the pearl cotton layer more stable and prevent displacement.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0026] The present application will be further described in detail below with reference to the accompanying drawings. Example
[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses an antistatic EPE for the protection of electronic equipment, including an antistatic protection structure 1. The antistatic protection structure 1 includes an antistatic layer 101, on which a pearl cotton layer 102 is abutted. Multiple fixing grooves 103 are formed on the inner end faces of both the pearl cotton layer 102 and the antistatic layer 101. Connecting posts 104 are inserted into two fixing grooves 103. Slots 105 are formed at both ends of the connecting posts 104. Insert rods 106 are inserted into the slots 105. Connecting rods 107 are connected and fixed to the multiple insert rods 106. The insert rods 106 have an L-shaped structure and the two ends of the connecting posts 104 have an arc-shaped structure.
[0028] In this embodiment, after the antistatic layer 101 or the pearl cotton layer 102 of the antistatic protection structure 1 is damaged, the insertion rod 106 on the connecting rod 107 can be inserted into the corresponding slot 105 of the connecting post 104 according to the corresponding requirements. This increases the connection strength between the connecting post 104 and the undamaged structure, allowing the antistatic layer 101 and the pearl cotton layer 102 to be directly pulled apart. The damaged structure can then be removed and the intact structure can be snapped on. Replacement is convenient, and the multi-point connection method provides a more stable connection. This design avoids the problem of large-area connection voids caused by the concentrated connection structure in the prior art, ensuring the tight connection between the antistatic layer 101 and the pearl cotton layer 102, thus guaranteeing the protective and antistatic effects. Example
[0029] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The insertion rod 106 and the limiting frame 2 are slidably connected on the insertion rod 106. The limiting frame 2 is connected and fixed with a fixing strip 3.
[0030] Multiple positioning rings 4 are connected and fixed on the fixing strip 3. The fixing strip 3, the limiting frame 2 and the positioning rings 4 located at the top and bottom are respectively connected and fixed to the antistatic layer 101 and the pearl cotton layer 102. Corresponding holes and grooves are opened inside the antistatic layer 101 and the pearl cotton layer 102.
[0031] The connecting rod 107 has pressing blocks 5 fixed at both ends, and the pressing blocks 5 slide in the grooves inside the antistatic layer 101 and the pearl cotton layer 102.
[0032] The pressing block 5 is fitted with a pressing rod 6, which is inserted into the groove on the outer wall of the antistatic layer 101 and the pearl cotton layer 102.
[0033] In this embodiment, during the process of the pressing rod 6 abutting against and driving the connecting rod 107 and the insertion rod 106 on the pressing block 5 to move, the limiting frame 2 can slide and limit them. On the one hand, it ensures that the connecting rod 107 drives the insertion rod 106 to move smoothly, and on the other hand, it ensures that the insertion rod 106 can be accurately inserted into the slot 105. The fixing strip 3 on the limiting frame 2, together with the positioning ring 4, can make the connection between the limiting frame 2 and the antistatic layer 101 and the pearl cotton layer 102 more stable and prevent displacement.
[0034] The implementation principle of the antistatic EPE for electronic equipment protection in this application embodiment is as follows: After the antistatic layer 101 or pearl cotton layer 102 of the antistatic protection structure 1 is damaged, the pressing rod 6 can be used to abut against and drive the pressing block 5 according to the corresponding needs. Then, the pressing block 5 drives the connecting rod 107 and its insert rod 106 to move under the limit of the limiting frame 2. Subsequently, the insert rod 106 is inserted into the slot 105 corresponding to the connecting post 104. This can increase the connection strength between the connecting post 104 and the undamaged structure. In this way, the antistatic layer 101 and the pearl cotton layer 102 can be directly pulled apart, and the corresponding damaged structure can be removed. Then, the intact structure can be snapped on and fixed. The replacement is more convenient, and the multi-point connection method is more stable.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
