Description

Technical Field

[0001] This utility model relates to the technical field of sealing equipment for metal products, specifically to rust-proof packaging and sealing equipment for metal products. Background Technology

[0002] During the storage and transportation of metal products (such as precision parts, tools, and machine components), the penetration of environmental moisture is a major factor leading to corrosion. Current mainstream rust-proof packaging technologies delay the oxidation reaction on the metal surface by sealing and isolating environmental moisture. Traditional sealing structures use rubber gaskets or mechanical pressing methods, which can provide basic moisture protection and meet the short-term protection needs under normal storage and transportation environments. However, the sealing reliability is insufficient during long-term use, and aging and deformation are prone to occur. At the same time, gaps are easily formed under vibration, allowing moisture to continuously penetrate and damage the metal products. Therefore, we propose rust-proof packaging and sealing equipment for metal products. Utility Model Content

[0014] The working principle of the rust-proof packaging and sealing device for metal products provided by this utility model is as follows: After the metal product is placed in the sponge box 2 of the storage box 1, the sealing plate 31 is closed so that the connecting frame 33 is inserted into the storage box 1. At this time, air is injected into the annular airbag 34 through the air injection pipe 61 of the air injection component 6. The expanded annular airbag 34 is tightly embedded in the groove of the inner wall of the storage box 1, forming the first airtight barrier. Figure 2As shown, when the sealing plate 31 is pressed down, it pushes the sealing frame 42 of the second sealing assembly 4 to move down and compress the spring 41. The reaction force of the spring 41 makes the upper end of the sealing frame 42 tightly inserted into the connecting groove of the sealing plate 31, forming a second mechanical seal. The calcium chloride adsorption bag 35 placed in the sealed space continuously absorbs residual moisture. The sponge plate 32 and the sponge box 2 buffer vibration to prevent damage to the metal products. After the sealing plate 31 is closed, the torsion spring 54 of the fastening assembly 5 drives the rotating tube 53 to rotate, which drives the fastening frame 55 to automatically press the upper surface of the sealing plate 31. Then, the actuating disk 76 of the bidirectional screw 74 of the rotating fixing assembly 7 is rotated, so that the two moving bars 72 move towards each other along the limiting rod 75, pushing the locking rod 73 to insert into the support hole on the side of the fastening frame 55 to achieve mechanical interlocking. The shut-off valve 62 closes the air injection pipe 61 to maintain the pressure of the annular airbag 34 and completes the full sealing state, thereby effectively preventing moisture from entering.
