Abstract
Description
Technical Field
[0001] This utility model relates to the field of shielding bag technology, and in particular to an antistatic self-sealing shielding bag. Background Technology
[0002] Antistatic shielding bags are commonly used for packaging electronic components to prevent damage caused by electrostatic discharge (ESD). Typically, antistatic shielding bags employ a two-layer composite or even a four-layer structure. The bag creates a Faraday cage effect, maximizing the isolation of the contents from the electrostatic field, preventing static electricity buildup, and protecting them from ESD hazards.
[0003] The antistatic self-sealing shielding bag mentioned in patent CN218318269U has a release film that is movably attached to the top of the adhesive layer. This allows users to seal the opening of the cavity by tearing off the release film from the top of the adhesive layer and then bending the part of the bag body that is longer than the top of the bag body. However, this patent uses an adhesive layer to seal the bag opening. After long-term use, the adhesive layer becomes less sticky, reducing the bonding effect on the bag body. This makes it difficult for the bag to self-seal, and the adhesive layer is still quite sticky when opening the bag, making it difficult to open the bag. Therefore, there is a need to provide an antistatic self-sealing shielding bag to solve the above problems. Utility Model Content

An extension bag 6 is fixedly connected to the top of the shielding bag 2, and the extension bag 6 is set vertically. An installation side plate 7 is fixedly connected to the inner wall of one side of the extension bag 6, and a connecting rail 8 is fixedly connected to the side of the installation side plate 7. A filling groove 11 is opened in the middle of the side of the connecting rail 8 away from the installation side plate 7, and a sealing filling strip 9 is fitted inside the filling groove 11. The sealing filling strip 9 is tightly connected to the connecting rail 8, and a connecting side plate 10 is fixedly connected to the side of the sealing filling strip 9 away from the connecting rail 8. The connecting side plate 10 is fixedly connected to the inner wall of the extension bag 6 away from the installation side plate 7. The shielding bag 2 and the antistatic shielding bag 3 enhance the strength of the shielding bag body 1. The sealing filling strip 9 is snapped into the filling groove 11 in the middle of the connecting rail 8, thereby achieving a seal on the shielding bag body 1. No adhesive connection is required, which facilitates the reuse of the shielding bag body 1. The connection plate 4 and the sealing connection plate 5 improve the connection stability between the antistatic shielding bag 3 and the shielding bag 2. Please see Figure 1 , Figure 2 , Figure 4As shown, the separator assembly 12 includes a mounting plate 13. A separator plate 14 is provided on the side of the mounting plate 13, and a magnetic adsorption strip 17 and an adsorption strip 18 are provided on one side of the separator plate 14. A connecting seat 15 and a mounting groove 16 are provided in the middle of the mounting plate 13. There are two mounting grooves 16, symmetrically distributed at both ends of the middle of the mounting plate 13. The connecting seat 15 is engaged in the middle of the mounting groove 16, and the connecting seat 15 penetrates the mounting plate 13 and connects to the interior of the extension bag 6. The end of the connecting seat 15 connected to the interior of the extension bag 6 is horizontally aligned with the inner wall of the extension bag 6. The top of the mounting plate 13 is fixedly connected to... A partition plate 14 is provided, with one end of the partition plate 14 away from the mounting plate 13 connected to the side of the extension bag 6 away from the connecting seat 15.

The outer wall of the antistatic shielding bag 3 is fixedly connected to the shielding bag 2 via the connecting plate 4 and the sealing connecting plate 5, thereby further improving the strength of the shielding bag body 1. Then, the connecting rail 8 and the sealing filling strip 9 are aligned, and the connecting rail 8 and the sealing filling strip 9 are pressed down, causing the sealing filling strip 9 to be pressed into the filling groove 11 on the side of the connecting rail 8 under force, thus sealing the shielding bag body 1. Next, the partition plate 14 at the top of the mounting plate 13 is snapped onto the outside of the extension bag 6, so that the magnetic adsorption strip 17 on the inner wall of the partition plate 14 contacts the adsorption strip 18 on the outer wall of the extension bag 6, thereby blocking the port of the extension bag 6 and preventing foreign matter from entering the interior of the extension bag 6 and entering the interior of the shielding bag body 1 when opened, affecting the storage effect. When opened, the side walls of the extension bag 6 are pulled away from the sides of the extension bag 6, causing the sealing filling strip 9 to separate from the connecting rail 8 under the action of tension, facilitating the reuse of the device.
