Description

Technical Field

[0001] This utility model relates to the field of electrostatic protection technology, and in particular to a parts storage cabinet that can prevent static electricity. Background Technology

[0002] Anti-static storage cabinets are widely used for electronic components, semiconductor chips, and precision instruments. When storing static-sensitive items, the instantaneous high voltage generated by electrostatic discharge can break down the insulation layer of semiconductor devices, leading to permanent failure. Alternatively, non-fatal electrostatic damage may reduce the long-term reliability of components and is difficult to detect through routine testing, thus becoming a potential hazard.

[0003] Currently available anti-static component storage cabinets can provide a stable and controllable internal environment, effectively preventing damage to electronic components caused by static electricity. However, most storage cabinets only have single functions of static shielding or static dissipation, and cannot simultaneously meet the needs of physical protection, moisture protection, and electromagnetic shielding. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a parts storage cabinet that can prevent static electricity, aiming to improve the problem that storage cabinets cannot provide multiple protections during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a parts storage cabinet capable of preventing static electricity, comprising an anti-static shell, with grounding terminals fixedly connected to the four corners of the bottom of the anti-static shell, an electromagnetic shielding layer fixedly connected to the bottom of the inner wall of the anti-static shell, a buffer layer fixedly connected to the bottom of the inner wall of the electromagnetic shielding layer, two cabinet doors provided on the front side of the anti-static shell, two hinges fixedly connected to each of the two cabinet doors and the anti-static shell, sealing frames fixedly connected to the rear side of each of the two cabinet doors, a sealing strip fixedly connected to the front side of the right cabinet door, two meshes fixedly connected between the left and right sides of the inner wall of the buffer layer, multiple guide rails provided on the rear side of the inner wall of the buffer layer, connecting frames fixedly connected to the top of two adjacent guide rails, elastic sponges fixedly connected to the bottom of the inner walls of the three connecting frames, silicone baskets fixedly connected to the top of the three elastic sponges, and a moisture-proof component provided inside the meshes.

[0006] Preferably, the moisture-proof component includes two connecting blocks, which are tightly fitted to the antistatic shell. A silicone strip is fixedly connected to the outer surface of each of the two connecting blocks. A groove is provided on the right side of each of the two connecting blocks, and a mesh frame is fixedly connected to the left side of each of the two connecting blocks. A moisture-absorbing pad is provided at the bottom inside the mesh frame.

[0007] Preferably, the two cabinet doors fit together tightly, and the joint between the two cabinet doors is an L-shape that interlocks with each other.

[0008] Preferably, the rear side of the sealing frame is tightly fitted to the front side of the antistatic housing, and the front side of the sealing strip is tightly fitted to the left cabinet door.

[0009] Preferably, the silicone basket has a shape with fences on the left, right, and rear sides, and the silicone basket fits tightly with the connecting frame.

[0010] Preferably, the top four guide rails are fixedly connected to the partition net, and the bottom two guide rails are fixedly connected to the bottom of the inner wall of the buffer layer.

[0011] Preferably, the mesh frame is a cuboid made of wire mesh, the moisture-absorbing pad is tightly fitted to the mesh frame, and the mesh frame is tightly fitted to the partition mesh.

[0012] Preferably, the right side of the connecting block is permeated by a buffer layer, an electromagnetic shielding layer, and an antistatic shell, and the silicone strip is tightly fitted to the antistatic shell.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting the two outer layers of the cabinet as an anti-static shell and an electromagnetic shielding layer, and setting a grounding terminal at the bottom of the anti-static shell, the static electricity in the cabinet is defended and conducted away. By setting a sealing frame and sealing strip on the cabinet door, the inside of the cabinet can be dustproof and moistureproof when the cabinet door is closed, thus solving the problem that the storage cabinet cannot provide multiple protections during use.

[0015] 2. In this utility model, a moisture-proof pad is set in the mesh to absorb moisture in the cabinet. The connecting block is designed to extend through to the outside of the anti-static shell. By snapping the groove on the right side of the connecting block, the connecting block can be pulled out, thereby pulling out the mesh frame and the moisture-proof pad together for quick replacement of the moisture-proof pad. This solves the problem of cumbersome replacement of moisture-proof components for storage cabinets. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of an anti-static parts storage cabinet, comprising an anti-static shell 1, with grounding terminals 5 fixedly connected to the four corners of the bottom of the anti-static shell 1, an electromagnetic shielding layer 2 fixedly connected to the bottom of the inner wall of the anti-static shell 1, a buffer layer 3 fixedly connected to the bottom of the inner wall of the electromagnetic shielding layer 2, two cabinet doors 6 on the front side of the anti-static shell 1, two hinges 4 fixedly connected to each of the two cabinet doors 6 and the anti-static shell 1, sealing frames 7 fixedly connected to the rear side of each of the two cabinet doors 6, a sealing strip 8 fixedly connected to the front side of the right cabinet door 6, two meshes 9 fixedly connected between the left and right sides of the inner wall of the buffer layer 3, multiple guide rails 10 on the rear side of the inner wall of the buffer layer 3, connecting frames 11 fixedly connected to the top of the two adjacent guide rails 10, elastic sponges 12 fixedly connected to the bottom of the inner walls of the three connecting frames 11, silicone baskets 13 fixedly connected to the top of the three elastic sponges 12, and a moisture-proof component inside the meshes 9.

[0024] Specifically, by setting the cabinet shell as an anti-static shell 1 and an electromagnetic shielding layer 2, static electricity is prevented externally and shielded internally. Static electricity generated on the cabinet is conducted away by the grounding terminal 5 at the bottom of the anti-static shell 1. At the same time, the innermost layer of the cabinet is set as a buffer layer 3, and the elastic sponge 12 and silicone basket 13 set at the bottom of the connecting frame 11 provide a cushioning effect for the items stored inside the cabinet, protecting the items from vibration and collision damage. Since the guide rail 10 is set at the bottom of the connecting frame 11, the items can be easily accessed by pulling out the connecting frame 11. When the cabinet door 6 is closed, the sealing frame 7 and sealing strip 8 are used to prevent dust and moisture inside the cabinet, solving the problem that the storage cabinet cannot provide multiple protections during use.

[0025] Reference Figure 4 The moisture-proof component includes two connecting blocks 16, which are tightly fitted to the antistatic housing 1. Silicone strips 18 are fixedly connected to the outer surface of each of the two connecting blocks 16. Grooves 17 are provided on the right side of each of the two connecting blocks 16. Mesh frames 14 are fixedly connected to the left side of each of the two connecting blocks 16. Moisture-absorbing pads 15 are provided at the bottom inside each of the two mesh frames 14.

[0026] Specifically, by setting a moisture-absorbing pad 15 in the partition 9, and by pulling the groove 17 on the connecting block 16 set on the outside of the antistatic housing 1, the connecting block 16, the mesh frame 14 and the moisture-absorbing pad 15 can be pulled out simultaneously to replace the moisture-absorbing pad 15, thereby maintaining the dehumidification effect. After the moisture-absorbing pad 15 is replaced, the moisture-absorbing component is pushed back into the partition 9, and the connection between the connecting block 16 and the antistatic housing 1 is sealed by the silicone strip 18 set on the outer surface of the connecting block 16. At the same time, since the silicone strip 18 is filled between the two, it prevents the connecting block 16 from falling off the antistatic housing 1 during daily use, thus solving the problem of cumbersome replacement of components for moisture protection of the storage cabinet.

[0027] Reference Figure 1 and Figure 2 The two cabinet doors 6 fit together tightly, and the joint between the two cabinet doors 6 is an L-shape that interlocks with each other.

[0028] Specifically, the two cabinet doors 6 are designed to interlock at the joint, so that when the cabinet doors 6 are closed, there is no large gap between them due to their interlocking.

[0029] Reference Figure 2 The rear side of the sealing frame 7 is tightly fitted to the front side of the antistatic housing 1, and the front side of the sealing strip 8 is tightly fitted to the left cabinet door 6.

[0030] Specifically, by setting a sealing frame 7 and a sealing strip 8 on the cabinet door 6, the sealing frame 7 and the sealing strip 8 fill the space between the cabinet door 6 and the antistatic outer shell 1 after the cabinet door 6 is closed, thus achieving the purpose of dust and moisture prevention inside the cabinet.

[0031] Reference Figure 3 The silicone basket 13 is shaped with fences on the left, right and rear sides, and the silicone basket 13 fits tightly with the connecting frame 11.

[0032] Specifically, by setting the silicone basket 13 in this shape, the items placed inside are protected by the railings on its three sides when the silicone basket 13 is pulled out of the cabinet.

[0033] Reference Figure 2 and Figure 3The top four guide rails 10 are fixedly connected to the partition net 9, and the bottom two guide rails 10 are fixedly connected to the bottom of the inner wall of the buffer layer 3.

[0034] Specifically, by setting two guide rails 10 at the bottom of each connecting frame 11, excessive friction can be avoided when the connecting frame 11 is pulled out, thus preventing the generation of static electricity.

[0035] Reference Figure 4 The frame 14 is a cuboid made of wire mesh. The moisture-absorbing pad 15 is tightly attached to the frame 14, and the frame 14 is tightly attached to the partition net 9.

[0036] Specifically, both the frame 14 and the partition 9 are made of hollow material, which facilitates the absorption of moisture inside the cabinet by the moisture-absorbing pad 15.

[0037] Reference Figure 4 The buffer layer 3, electromagnetic shielding layer 2 and antistatic shell 1 pass through the right side of the connecting block 16 in sequence, and the silicone strip 18 is tightly attached to the antistatic shell 1.

[0038] Specifically, when the connecting block 16 is inserted into the antistatic housing 1, the silicone strip 18 on its outer surface not only isolates the inside and outside of the cabinet, but also allows the connecting block 16 to be engaged in the antistatic housing 1 through the friction of the silicone strip 18.

[0039] Working principle: When using the storage cabinet to store items, the cabinet shell is set as an anti-static shell 1 and an electromagnetic shielding layer 2, thereby preventing static electricity from the outside and shielding it from the inside. The static electricity generated on the cabinet is conducted away by the grounding terminal 5 at the bottom of the anti-static shell 1. At the same time, the innermost layer of the cabinet is set as a buffer layer 3, and the elastic sponge 12 and silicone basket 13 set at the bottom of the connecting frame 11 provide a cushioning effect for the items stored inside the cabinet, protecting the items from vibration and collision damage. Since the guide rail 10 is set at the bottom of the connecting frame 11, the items can be easily accessed by pulling out the connecting frame 11. When the cabinet door 6 is closed, the sealing frame 7 and sealing strip 8 are used to prevent dust and moisture inside the cabinet.

[0040] When the moisture-proof pad 15 in the storage cabinet needs to be replaced, the connecting block 16, the wire mesh frame 14 and the moisture-absorbing pad 15 are pulled out simultaneously by pulling the groove 17 on the connecting block 16 set on the outside of the antistatic housing 1 to replace the moisture-absorbing pad 15. After replacement, the moisture-absorbing component is pushed back into the mesh 9, and the connection between the connecting block 16 and the antistatic housing 1 is sealed by the silicone strip 18 set on the outer surface of the connecting block 16. At the same time, since the silicone strip 18 is filled between the two, it prevents the connecting block 16 from falling off the antistatic housing 1 during daily use.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
