[0024] like Figure 1-4 As shown, this utility model discloses a high-sealing polyurethane gasket storage device, comprising a storage box 1, a lid 2 mounted on the top of the storage box 1, an inner frame 3 welded inside the lid 2, the surface of the inner frame 3 being attached to the inner wall of the storage box 1, and a sealing frame 4 bonded to the inside of the lid 2. By installing the sealing frame 4, a sealing effect is provided between the storage box 1 and the lid 2, preventing water from entering the gap between the lid 2 and the storage box 1, thus providing a sealing effect during use. The bottom of the sealing frame 4 is attached to the top of the storage box 1. A vacuum pump 5 is welded to the top of the lid 2, and an air pipe 8 is mounted on the surface of the vacuum pump 5. The air pipe 8... The sealing seat 10 is embedded inside the lid 2. A valve 9 is installed on the surface of the air pipe 8. A control device 6 and a power supply device 7 are welded to the top of the lid 2. By installing a vacuum pump 5, a vacuum can be created between the lid 2 and the inside of the storage box through the air pipe 8. During this process, because the air pressure inside the device is lower than the external air pressure, the sealing frame 4 is squeezed between the storage box 1 and the lid 2, thereby improving the sealing effect. After a certain amount of air is extracted, the valve 9 can be closed to prevent the air pressure inside the box from flowing back through the air pipe 8. At this time, the device can have a high sealing effect and strong sealing performance during use.

[0025] The top of the cover 2 is fixedly connected to the fixing seat 15. The fixing seat 15 is internally fitted with the shaft 19. The fixing strip 16 is welded to one end of the shaft 19. The fixing strips 16 are symmetrically distributed. The side of the fixing strip 16 is welded with the handle 17. By installing the handle 17, when it is necessary to carry or move the device, the handle 17 can be used as the force point. The device can be directly driven through the handle 17, which is very convenient to use.

[0026] A threaded rod 11 is welded to the top of the cover 2. A protective cover 20 is provided on the top of the cover 2. The power supply device 7 and the control device 6 are both located inside the protective cover 20. A side plate 21 is welded to the side of the protective cover 20. The threaded rod 11 passes through the side plate 21. A nut 12 is sleeved on the surface of the threaded rod 11. One end of the nut 12 is attached to the top of the side plate 21. By installing the protective cover 20, the control device 6 and the power supply device 7 can be hidden, thereby protecting the control device 6 and the power supply device 7. The protective performance is strong during use.

[0027] The storage box 1 has a card block 14 welded to its surface, and the bottom of the box cover 2 is fixedly connected to a card frame 13. The card frame 13 is fitted with the card block 14 inside. The card frames 13 are symmetrically distributed. By installing the card frame 13 and the card block 14, when installing the box cover 2, the card frame 13 can be used to fit the card block 14, which can provide a fixed installation effect for the box cover 2, making it very convenient to use.

[0028] The protective cover 20 has a slot 22 at the top, and the control device 6 is at the bottom of the slot 22. By opening the slot 22, the control device 6 can be provided with operating space. At this time, the control device 6 can be used directly through the slot 22, which is very convenient to use.

[0029] The fixed base 15 is symmetrically distributed, and the grip 17 is bonded with an anti-slip sleeve 18. By installing the anti-slip sleeve 18, the friction of the grip 17 surface can be increased, so that the palm can be anti-slip when holding the grip 17, thus improving the stability of the grip during use.

[0030] The working principle of this highly airtight polyurethane gasket storage device is as follows: When using this device, a lid 2 is installed on the top of the storage box 1, and an inner frame 3 is welded inside the lid 2. The surface of the inner frame 3 adheres to the inner wall of the storage box 1. Simultaneously, a sealing frame 4 is bonded inside the lid 2, with its bottom adhering to the top of the storage box 1. A vacuum pump 5 is welded to the top of the lid 2, and an air pipe 8 is installed on the surface of the vacuum pump 5. The air pipe 8 is embedded inside the lid 2 through a sealing seat 10, and a valve 9 is installed on the surface of the air pipe 8. A control device 6 and a power supply device 7 are welded to the top of the lid 2. The power supply device 7, control device 6, and vacuum pump 5 are connected by an electrical circuit. When using this device, the polyurethane gasket can be placed inside the storage box 1 first, and then the lid 2 can be installed on top of the storage box 1. When installing the lid 2, the clip frame 13 can be used to engage the clip block 14, thus providing a fixed installation effect for the lid 2. At this time, the bottom of the sealing frame 4... The device is attached to the top of the storage box 1. Then, the vacuum pump 5 is started by the control device 6, and the power supply device 7 provides support for the vacuum pump 5. At this time, the vacuum pump 5 will evacuate the lid 2 and the inside of the storage box through the air pipe 8. During this process, since the air pressure inside the device is lower than the outside air pressure, the sealing frame 4 is squeezed between the storage box 1 and the lid 2, thereby improving the sealing effect. After a certain amount of air is extracted, the valve 9 can be closed to prevent the air pressure inside the box from flowing back through the air pipe 8. At this time, the device has a high sealing effect and strong sealing performance during use. When it is necessary to remove the polyurethane pad, the valve 9 can be opened first. At this time, outside air will enter the inside of the storage box 1 through the air pipe 8. When the air pressure inside the storage box 1 is the same as the outside air pressure, the card frame 13 and the card block 14 can be separated. Then, the lid 2 can be removed directly, which will expose the space inside the storage box 1. Then, the polyurethane pad can be removed directly.

[0031] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
