Description

Technical Field

[0001] This utility model relates to the field of antistatic bag technology, and in particular to a multi-layer antistatic shielding bag. Background Technology

[0002] Antistatic shielding bags are packaging materials specifically designed to protect static-sensitive components. They combine antistatic and electromagnetic shielding functions and are widely used in electronics, semiconductors, communications, and other fields. When using existing antistatic shielding bags, excess air needs to be drawn out to save floor space. However, when it is necessary to remove static-sensitive components from the bag, air cannot quickly enter the bag after opening the opening, requiring the user to manually open the shielding bag to access the components, which reduces work efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where vacuum-sealed bags save space but require users to manually open the bag to access components, thus reducing access efficiency. Therefore, this invention proposes a multi-layer anti-static shielded bag.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a multi-layer antistatic shielding bag, including a bag body, a fixing ring adhered to the bag body, a sealing plate slidably connected inside the fixing ring, an air extraction nozzle fixedly connected to the surface of the bag body, and a bag body opening assembly, the bag body opening assembly including two rotating shafts, the rotating shafts being rotatably connected to the fixing ring, an opening frame fixedly connected to the side of the rotating shafts, and a plurality of opening plates fixedly connected to the opening frame, the opening frame and the opening plates being adhesively fitted to the bag body.

[0006] Preferably, the pivot shaft extends through the bag body.

[0007] Preferably, a gear is fixedly connected to the end of the rotating shaft, four sets of guide rails are symmetrically fixedly connected to the fixed ring, and a rack is slidably connected inside the guide rail, with the gear and rack meshing with each other.

[0008] Preferably, four sliding rods are slidably connected to the fixed ring, a cross plate is fixedly connected between two adjacent sliding rods, an L-shaped rod is fixedly connected to the end of each sliding rod, and the L-shaped rod is fixedly connected to the rack.

[0009] Preferably, a spring is fixedly connected between the cross plate and the fixing ring.

[0010] Preferably, two partitions are symmetrically arranged inside the bag.

[0011] Preferably, a sealing plug is threaded onto the air extraction nozzle.

[0012] Preferably, the sealing plate is fixedly connected to a pull lug on its side.

[0013] The multi-layer antistatic shielding bag proposed in this utility model has the following advantages: When the sealing plate is opened during use, the air pressure inside the bag returns to normal, the spring pushes the rack to move downwards, the rack moves and drives the gear to rotate, and the gear rotates the shaft and the opening frame to rotate at a certain angle, thereby automatically opening the bag during storage and retrieval, improving work efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figure 1-5This utility model is a multi-layer antistatic shielding bag, including a bag body 1, a fixing ring 2 bonded to the bag body 1, a sealing plate 3 slidably connected inside the fixing ring 2, an air extraction nozzle 4 fixedly connected to the surface of the bag body 1, and a bag body 1 opening assembly, which includes two rotating shafts 5, the rotating shafts 5 being rotatably connected to the fixing ring 2, an opening frame 6 fixedly connected to the side of the rotating shafts 5, and several opening plates 7 fixedly connected to the opening frame 6, both the opening frame 6 and the opening plates 7 being bonded to the bag body 1.

[0024] The rotating shaft 5 passes through the bag body 1. Two partition plates 15 are symmetrically arranged inside the bag body 1. A sealing plug 16 is threaded onto the air extraction nozzle 4. A pull lug 17 is fixedly connected to the side of the sealing plate 3.

[0025] The operation process of this embodiment is as follows: the bag body 1 is an anti-static shielding bag. When using this device, the static-sensitive components to be stored are placed in the bag body 1. Different components are separated by the partition plate 15. After the components are loaded, the pull ear 17 is pushed so that the sealing plate 3 seals the fixing ring 2. Then, the gas in the bag body 1 is extracted from the air extraction nozzle 4, thereby reducing the area occupied by the device.

[0026] When storage or retrieval is required, the pull tab 17 is moved, causing the sealing plate 3 to move as well. However, outside air cannot quickly fill the bag 1, requiring the user to manually open the bag 1 to access the components. In this case, the two rotating shafts 5 are rotated synchronously in opposite directions, such as... Figure 3 As shown, the rotation of the shaft 5 drives the expansion frame 6 to rotate, and the rotation of the expansion frame 6 drives the expansion plate 7 to move. Since both the expansion frame 6 and the expansion plate 7 are bonded to the bag body 1, rotating the shaft 5 can quickly expand the bag body 1, thereby improving the user's work efficiency.

[0027] Example 2

[0028] While rotating the pivot 5 can open the bag 1, it still requires manual rotation, making the operation somewhat cumbersome. Therefore, please refer to [the relevant documentation / reference needed]. Figure 3-5 Based on the first specific embodiment, a gear 8 is fixedly connected to the end of the rotating shaft 5, four sets of guide rails 9 are symmetrically fixedly connected to the fixed ring 2, a rack 10 is slidably connected inside the guide rail 9, the gear 8 and the rack 10 mesh with each other, four slide rods 11 are slidably connected to the fixed ring 2, a cross plate 12 is fixedly connected between two adjacent slide rods 11, an L-shaped rod 14 is fixedly connected to the end of the slide rod 11, the L-shaped rod 14 is fixedly connected to the rack 10, and a spring 13 is fixedly connected between the cross plate 12 and the fixed ring 2.

[0029] The operation process of this embodiment is as follows: In the initial state, the spring 13 always pushes the horizontal plate 12 and the slide bar 11 to move downward. The movement of the slide bar 11 drives the L-shaped bar 14 and the rack 10 to move. The rack 10 limits the position of the gear 8 so that the support frame 6 always maintains a fixed angle when the bag body 1 is not closed for air extraction. That is, the bag body 1 always remains open when it is not being extracted. When storing, the horizontal plate 12 is pulled upward. The horizontal plate 12 moves and stretches the spring 13, and drives the slide bar 11, the L-shaped bar 14 and the rack 10 to move upward. The rack 10 moves downward and drives the gear 8 to rotate. The rotation of the gear 8 reduces the space inside the bag body 1, making it easier to extract air from the extraction nozzle 4. After the air extraction is completed, the sealing plug 16 is used to seal the space inside the bag body 1.

[0030] When storage or retrieval is required, the sealing plate 3 is pulled out to the outside. At this time, the air pressure inside the bag 1 returns to normal, the spring 13 resets and drives the rack 10 to move downward. The movement of the rack 10 drives the gear 8 to rotate. The rotation of the gear 8 drives the rotating shaft 5 and the opening frame 6 to open the bag 1 again. That is, when the sealing plate 3 is opened, the spring 13 resets and can automatically open the opening frame 6, further improving the efficiency of storage and retrieval.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
