Description

Technical Field

[0001] This utility model relates to the field of storage and organization technology, and in particular to an inflatable, sealed, moisture-proof storage box. Background Technology

[0002] With the booming development of the consumer electronics industry, the number of electronic products such as smartphones, tablets, professional cameras, and drones continues to rise. The accessories such as chargers, lenses, memory cards, and batteries that accompany them are also becoming increasingly abundant. These electronic products and accessories have strict requirements for environmental humidity, sealing, and damage prevention during storage. Humid environments can easily lead to oxidation and corrosion of circuit boards and poor contact of contacts. Dust intrusion may affect the operating accuracy of precision components, while accidental friction and collision can cause scratches or functional damage. Therefore, special storage boxes have become an essential tool for the maintenance of electronic devices.

[0003] Existing moisture-proof storage boxes for electronic components mostly employ a fixed sealing structure. Their core sealing relies on a combination of silicone sealing rings, rubber gaskets, and snap-fit ​​or threaded clamps. Specifically, the contact area between the box body and the lid has a pre-set groove containing an elastic sealing element. Through snap-fitting or threaded tightening, the sealing element is tightly fitted to the contact surface, thus blocking external moisture and dust. While this type of fixed sealing structure meets basic sealing requirements in the initial stage, it has technical defects in the long term. Firstly, the sealing performance of fixed sealing structures deteriorates significantly. Over long-term use, the silicone and rubber elastic sealing elements age and deform due to frequent compression, friction, and changes in ambient temperature, causing their fit with the box body and lid to gradually decrease, and the sealing gap to increase accordingly. Meanwhile, clamping components such as buckles and threads may wear or loosen due to repeated stress, further weakening the sealing effect. When the sealing performance drops to a certain level, external humid air and dust will continuously seep into the box, which may not only cause oxidation of the metal interfaces of electronic devices, but also significantly increase the risk of malfunctions such as fogging of lens elements and battery bulging, failing to provide long-term stable storage protection for electronic products. On the other hand, the operation convenience and adaptability of the fixed sealing structure are poor. To ensure the sealing effect, the buckles of these storage boxes are usually designed to be tight, or the thread engagement stroke is long, which means that a large external force must be applied during opening and closing, making operation laborious and prone to causing bumps to the edges of the box. At the same time, the size and shape of the fixed sealing components are fixed, and the sealing pressure cannot be flexibly adjusted according to the placement of items in the box.

[0004] Therefore, to address the aforementioned technical pain points, an inflatable, sealed, moisture-proof storage box can be designed. This box uses an inflatable airbag to replace the traditional fixed seal. By inflating the airbag, it expands and tightly fills the gap between the box body and the lid, forming an adaptive sealing layer that improves the stability of the sealing structure and operational flexibility. Utility Model Content

[0005] To overcome the problem that most electronic component moisture-proof storage boxes have fixed sealing structures, long-term repeated stress will reduce the sealing effect, and fixing the sealing structure requires a large external force to ensure the sealing effect, resulting in poor operation convenience and inability to adapt to storage boxes of different shapes.

[0006] The technical solution of this utility model is as follows: an inflatable and sealed moisture-proof storage box, including a box body and a box lid, with the box lid hinged to one side of the box body, multiple storage compartments provided inside the box body, and an inflatable and deflated sealing airbag disposed between the box body and the box lid, with an inflation port provided on one side of the sealing airbag, and an inflation device connected to the inflation port. The sealing airbag is inflated or deflated through the inflation port to adjust the sealing between the box body and the box lid.

[0007] Preferably, the opening edge of the box body is provided with an annular groove, and a sealing airbag is embedded in the groove. The edge of the groove is set as a slope to limit the expansion direction of the sealing airbag.

[0008] Preferably, a vent valve is installed on the outside of the sealing airbag to release the gas inside the sealing airbag.

[0009] Preferably, a locking block is fixedly connected to the other side of the box, and a slot matching the locking block is opened on the outer wall of the box lid.

[0010] Preferably, a limiting mechanism is provided in the groove, which includes a wedge-shaped slide rail and a wedge-shaped slider. The edge of the groove is provided with a wedge-shaped slide rail, and the outside of the sealing airbag is provided with a wedge-shaped slider that matches the wedge-shaped slide rail.

[0011] Preferably, a sealing strip is installed on the top of the wedge-shaped slider.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared to existing moisture-proof storage boxes, the contact method between the sealing airbag and the box body is changed from the traditional rigid friction to a flexible fit. The sealing airbag can be deflated to shrink, which greatly reduces frictional wear between components and effectively slows down the decay of sealing performance. At the same time, the sealing pressure can be flexibly controlled by adjusting the inflation volume. It can not only adapt to storage box structures of different sizes, but also achieve dynamic sealing adjustment according to the storage needs of items, perfectly meeting the needs of electronic products for a long-term stable storage environment.

[0014] 2. The sealing airbag is transformed from a wear-prone sealing actuator into a pure and efficient power source. The expansion force of the sealing airbag is converted into a mechanical locking force with self-locking characteristics through a limiting mechanism, thus solving the problem of frictional loss of the sealing airbag.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] Please see Figures 1-4 This utility model provides an embodiment of an inflatable, sealed, moisture-proof storage box, comprising a box body 1 and a lid 2. The lid 2 is hinged to one side of the box body 1. The box body 1 is provided with multiple storage compartments 102. It also includes an inflatable and deflated sealing airbag 3 disposed between the box body 1 and the lid 2. An inflation port 301 is provided on one side of the sealing airbag 3. An inflation device is connected to the inflation port 301. The sealing airbag 3 is inflated or deflated through the inflation port 301 to adjust the sealing between the box body 1 and the lid 2.

[0026] In this embodiment, the inflation device can be an inflatable bladder. The inflation bladder is equipped with a one-way valve at the inflation end to prevent gas from flowing back out of the sealing bladder 3. By squeezing the inflatable bladder, air is injected into the inflation port 301, causing the sealing bladder 3 to expand and fit tightly against the mating edge of the box body 1 and the box cover 2 for sealing. The inflation device can also be an air pump or a gas generator.

[0027] In this embodiment, an annular groove 101 is provided at the edge of the opening of the box body 1, and a sealing airbag 3 is embedded in the groove 101. The edge of the groove 101 is set as a slope to restrict the expansion direction of the sealing airbag 3. When the sealing airbag 3 is not inflated, it is flat in the annular groove 101. After inflation, the sealing airbag 3 expands along the slope of the groove 101, squeezing the groove 101 and restricting the deformation of the sealing airbag 3 in the ineffective direction.

[0028] In this embodiment, a vent valve 5 is installed on the outside of the sealing airbag 3. The vent valve 5 is used to release the gas inside the sealing airbag 3. By rotating the vent valve 5, the air inside the sealing airbag 3 is discharged, and the cover 2 is opened.

[0029] In this embodiment, a locking block 6 is fixedly connected to the other side of the box body 1, and a locking groove 601 matching the locking block 6 is opened on the outer wall of the box cover 2, so that the box body 1 and the box cover 2 are closed by locking.

[0030] When storing electronic accessories, place the accessories in the storage compartment 102, rotate the lid 2 around one side of the box body 1 to engage the slot 601 with the block 6, and use an inflation device to inject gas from the inflation port 301 into the sealing airbag 3. The sealing airbag 3 gradually expands in the groove 101 and fills the gap between the lid 2 and the box body 1 along the inclined surface of the groove 101 to complete the seal.

[0031] When removing the electronic components, turn the vent valve 5 to expel the air from the sealed airbag 3. The sealed airbag 3 will then retract back into the groove 101, releasing the seal and opening the storage box.

[0032] Example 2

[0033] In Example 1, the sealing airbag 3 is directly used to seal the gap between the lid 2 and the body 1. In order to further improve the sealing reliability, the inflation sealing mechanism can be changed, and the sealing airbag 3 can be changed from a sealing element to a driving element. The sealing airbag 3 can be used to flexibly drive the fixed sealing element, thereby reducing the wear on the sealing airbag 3 itself.

[0034] Please see Figures 5-7 In another embodiment of this utility model, a limiting mechanism is provided in the groove 101. The limiting mechanism includes a wedge-shaped slide rail 4 and a wedge-shaped slider 401. The edge of the groove 101 is provided with a wedge-shaped slide rail 4. The outside of the sealing airbag 3 is provided with a wedge-shaped slider 401 that matches the wedge-shaped slide rail 4. A sealing strip 402 is installed on the top of the wedge-shaped slider 401.

[0035] In this embodiment, the sealing strip 402 is made of silicone or rubber. When inflated, the main direction of expansion of the sealing airbag 3 is guided to push the wedge slider 401 upward along the wedge slide rail 4. The wedge slide rail 4 is provided with protrusions to restrict the wedge slider 401 from sliding along a fixed path, thereby driving the sealing strip 402 to fill the gap, thus generating a composite sealing force that includes both vertical pressing force and horizontal locking force. While restricting the expansion direction of the sealing airbag 3, the expansion force of the airbag is converted into a mechanical locking force to assist in sealing and improve the reliability and durability of the sealing airbag 3. After deflation, the sealing airbag 3 contracts and drives the wedge slider 401 back to its original position along the wedge slide rail 4. The vertical pressing force and horizontal tension force are released, and the cover 2 can be easily opened.

[0036] Through the above steps, compared with existing moisture-proof storage boxes, the contact method between the sealing airbag 3 and the box body 1 is changed from the traditional rigid friction to a flexible fit. The sealing airbag 3 can be deflated to shrink, which greatly reduces the frictional loss between components and effectively delays the decay of sealing performance. At the same time, the sealing pressure can be flexibly controlled by adjusting the inflation volume. It can not only adapt to the structure of storage boxes of different specifications, but also achieve dynamic sealing adjustment according to the storage needs of items, perfectly meeting the needs of electronic products for long-term stable storage environment. The sealing airbag 3 is transformed from a easily worn sealing actuator into a pure and efficient power source. The expansion force of the sealing airbag 3 is transformed into a mechanical locking force with self-locking characteristics through the limiting mechanism, which solves the problem of frictional loss of the sealing airbag 3.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
