Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron magnet production technology, specifically to a moisture-proof packaging structure for neodymium iron boron magnets. Background Technology

[0002] Currently, packaging structures are needed to package neodymium iron boron magnets during their production process. This facilitates the repackaging, transportation, and sales of the magnets. Additionally, the outer packaging provides some protection against scratches caused by impacts.

[0003] Existing NdFeB magnet packaging typically consists of an inner plastic bag and an outer white paper box. The NdFeB magnets are individually packaged in the plastic bags, and then multiple packages are stacked in the white paper box. However, this packaging structure lacks moisture protection and is easily affected by humid air during storage and transportation. Because NdFeB magnets contain a high amount of iron, they are prone to oxidation and corrosion in humid environments, reducing their overall performance and lifespan, which is detrimental to their use.

[0004] To address this, a moisture-proof packaging structure using neodymium iron boron magnets is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a moisture-proof packaging structure for neodymium iron boron magnets, which solves the problem that existing neodymium iron boron magnet packaging structures lack moisture-proof function, and that the external humid environment will cause corrosion to neodymium iron boron magnets during transportation and storage, reducing the overall performance and service life of neodymium iron boron magnets.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A moisture-proof packaging structure for neodymium iron boron magnets includes a shell. A cushioning assembly is fixedly connected to the bottom of the shell's inner cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a screw to control the threaded sleeve and adjusting rod to press the inclined surface of the push block, causing the two push blocks to control the reinforcing frame to move downward. The reinforcing frame then controls the pressure plate to press the sealing cover downward.

A sealing cover 4 is fitted on the top of the shell 1 to seal the top of the shell 1. A rubber ring 5 is fixedly connected to the top of the inner cavity of the sealing cover 4. The rubber ring 5 can deform under pressure and fill the gap between the sealing cover 4 and the shell 1 to prevent the external humid environment from affecting the neodymium iron boron magnets inside the shell 1. A reinforcing frame 6 is provided at the bottom of the shell 1 to increase the strength of the shell 1. The reinforcing frame 6 has two pressure plates 7 that are movably connected to the top of the reinforcing frame 6. The pressure plates 7 can squeeze the sealing cover 4 and compress the rubber ring 5 downwards. Push blocks 8 are fixedly connected to the top of the inner cavity of the reinforcing frame 6. The push blocks 8 can cooperate with the adjusting rod 11 to control the movement of the reinforcing frame 6. The top of the push blocks 8 extends into the inner cavity of the housing 1. The rear side of the right side of the inner cavity of the housing 1 is movably connected to the screw 9. The two sides of the surface of the screw 9 are threaded with threaded sleeves 10. The threaded sleeves 10 can cooperate with the screw 9 to control the movement of the two adjusting rods 11. The front side of the threaded sleeves 10 is movably connected to the adjusting rod 11. The left side of the screw 9 extends into the outer side of the housing 1.

[0025] As one embodiment of this utility model, refer to Figure 3 and Figure 4 The buffer assembly 2 includes a buffer shell 201, the bottom of which is fixedly connected to the inner wall of the housing 1. A movable plate 202 is provided inside the buffer shell 201. The movable plate 202 can control the push roller 204 to compress the elastic rubber ring 205, and simultaneously stretch the tension spring 207 to absorb impact. A pressure rod 203 is fixedly connected to the top of the movable plate 202, which can transmit the impact force received by the positioning plate 3 to the movable plate 202. The top of the pressure rod 203 extends through the inner cavity of the housing 1. Push rollers 204 are movably connected to both sides of the bottom of the movable plate 202, and the push rollers 204 can compress the elastic rubber ring. 205 is squeezed to deform the elastic sheet 206. An elastic rubber ring 205 is provided at the bottom of the inner cavity of the buffer shell 201. The elastic sheet 206 is fixedly connected between the two sides of the elastic rubber ring 205 and the buffer shell 201. The elastic sheet 206 can absorb the impact force after contraction. A tension spring 207 is sleeved on the surface of the pressure rod 203. The tension spring 207 can buffer the movable plate 202 and use its tension after being stretched to offset the impact force. The top and bottom of the tension spring 207 are fixedly connected to the buffer shell 201 and the movable plate 202 respectively. The top of the buffer shell 201 has a through hole that cooperates with the pressure rod 203.

[0026] As one embodiment of this utility model, refer to Figure 1 , Figure 2and Figure 3 A sliding rod is fixedly connected to the front side between the two sides of the inner cavity of the housing 1. Sliding sleeves are slidably connected to both sides of the sliding rod surface. The rear side of the sliding sleeves is movably connected to the adjusting rod 11. The sliding rod and sliding sleeves can limit the adjusting rod 11, allowing it to move smoothly left and right, preventing the adjusting rod 11 from shifting when pressing the push block 8. A slide rail is fixedly connected to the rear side of the inner cavity of the housing 1. A slider is slidably connected to the inner cavity of the slide rail. The front side of the slider is fixedly connected to the threaded sleeve 10. The sliding sleeves and slider can limit the threaded sleeve 10, preventing it from rotating during movement. The threads on both sides of the screw 9 surface are opposite. A knob 12 is fixedly connected to the left side of the screw 9. Knob 12 allows operators to easily rotate screw 9 to seal and lock the sealing cover 4. The right side of screw 9 is movably connected to housing 1 via bearing. The bearing increases the stability of screw 9 during rotation. The bottom of pressure plate 7 is provided with anti-slip texture, which increases the anti-slip effect of pressure plate 7. Support plates are fixedly connected to the front and rear sides of the bottom of reinforcing frame 6. The support plates improve the protection effect of reinforcing frame 6 on housing 1. Guide strips are fixedly connected to both sides of the inner cavity of housing 1. Guide grooves are opened on both sides of positioning plate 3 to cooperate with guide strips. The guide strips and guide grooves can limit the positioning plate 3 and prevent it from shaking inside housing 1.

[0027] Working principle: After the neodymium iron boron magnets are placed inside the plastic bag, they are evenly arranged into the groove of the positioning plate 3. After covering with another positioning plate 3 and the sealing cover 4, the two pressure plates 7 are rotated so that they contact the top of the sealing cover 4. The knob 12 is rotated, and the knob 12 cooperates with the screw 9 to control the movement of the threaded sleeve 10 and the adjusting rod 11. The movement of the adjusting rod 11 presses the inclined surface of the push block 8, causing the push block 8 to control the reinforcing frame 6 to move downward. The movement of the reinforcing frame 6 controls the pressure plate 7 to press the top of the sealing cover 4, so that the sealing cover 4 and the shell 1 compress the rubber ring 5, causing the rubber ring 5 to deform and fill the gap between the sealing cover 4 and the shell 1. The inside of the shell 1 is filled with... The enclosure is completely sealed to prevent external humidity from affecting the neodymium iron boron magnets stored inside, thus preventing them from rusting after getting damp. During transportation, if the magnets encounter bumps or collisions, the positioning plate 3 moves downwards, transmitting the impact force to the push roller 204 through the pressure rod 203 and the movable plate 202. When the push roller 204 is compressed, it stretches the elastic ring 205. The elastic ring 205 absorbs the impact force when stretched, and at the same time, it squeezes the two elastic plates 206. When the two elastic plates 206 are compressed, they can also absorb part of the impact force. The remaining impact force is absorbed by the stretched tension spring 207, preventing the neodymium iron boron magnets from being damaged by impacts during transportation.
