Description

Technical Field

[0001] This utility model relates to the field of PCB board storage technology, and more specifically, to a moisture-proof storage device for PCB boards. Background Technology

[0002] In the electronics manufacturing industry, PCB (printed circuit board) is a key component of electronic devices. Its storage environment is crucial to maintaining its performance and extending its service life. Moisture-proof storage is an effective means to ensure that PCB is protected from humidity, prevent oxidation, corrosion and short circuits. Traditional PCB moisture-proof storage devices usually use moisture-proof boxes with built-in desiccants to absorb moisture inside the box and maintain a low humidity environment.

[0003] However, a significant problem exists in existing technologies: when PCB boards need to be placed or removed, the lid of the desiccant box is opened, exposing the desiccant inside to the outside air. Because the desiccant is hygroscopic, its drying effect rapidly decreases upon contact with humid air, thus shortening its effective lifespan and reducing the dehumidifying performance of the desiccant box. Therefore, we propose an improvement to address this issue by developing a moisture-proof storage device for PCB boards. Utility Model Content

[0004] The purpose of this invention is to address the problem that the desiccant absorbs moisture from the external environment when the lid is opened.

[0005] In order to achieve the above-mentioned objectives, this utility model provides a moisture-proof storage device for PCB boards to improve the above-mentioned problems.

[0006] The application is as follows:

[0007] A moisture-proof storage device for PCB boards includes a storage box and a box cover body installed on the storage box. A cover plate is fixedly installed on the box cover body. A cavity for placing desiccant is provided between the cover plate and the box cover body. A plurality of control components are provided between the box cover body and the cover plate. The control components are used to control the opening and closing of the cavity and the storage box.

[0008] The control component includes a rotating shaft rotatably connected between the cover plate and the main body of the box cover via a sealed bearing. The bottom end of the rotating shaft is connected to a baffle located below the main body of the box cover. The baffle has a plurality of second air ports. The bottom of the main body of the box cover has a plurality of first air ports. The number and position of the first air ports correspond to the number and position of the second air ports.

[0009] As a preferred technical solution of this application, a turntable is fixedly connected to the top of the rotating shaft, and the turntable is in contact with the top of the cover plate.

[0010] As a preferred technical solution of this application, the cover plate is provided with a pick-up and drop-out port, and a sealing cap is threadedly connected to the inner wall of the pick-up and drop-out port.

[0011] As a preferred technical solution of this application, handles are installed on the sealing cover, turntable and box cover body.

[0012] As a preferred technical solution of this application, a hinge is provided between one side of the box cover body and the storage box body, and a locking element is provided between the side of the box cover body away from the hinge and the storage box body.

[0013] As a preferred technical solution of this application, the locking component includes a latch installed on the storage box and a hook installed on the box cover body, and the hook and the latch are connected.

[0014] As a preferred technical solution of this application, the top of the storage box is connected to a sealing gasket, and the sealing gasket is in contact with the bottom of the box cover body.

[0015] As a preferred technical solution of this application, the front of the storage box is threaded with a hand-tightening bolt. One end of the hand-tightening bolt extends into the storage box and is rotatably connected to a sliding plate via a bearing. Several second limiting frames are fixedly connected to the side of the sliding plate away from the hand-tightening bolt. Several first limiting frames are fixed on the inner wall of the storage box away from the sliding plate. The positions of the first limiting frames correspond to the positions of the second limiting frames. Protective pads are installed inside both the second limiting frames and the first limiting frames.

[0016] As a preferred technical solution of this application, the bottom of the second limiting frame is slidably connected to the bottom of the inner cavity of the storage box.

[0017] As a preferred technical solution of this application, a support plate is installed inside the storage box. The support plate is located between the first limiting frame and the second limiting frame, and the support plate is used to support the PCB board.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] To address the problem in existing technologies where desiccants absorb moisture from the external environment when the lid is opened, this application addresses this issue by placing the desiccant between the lid body and the cover plate. Before opening the lid body, a baffle is rotated to offset the second air vent from the first air vent, thereby sealing the cavity between the lid body and the cover plate. This isolates the desiccant from the outside air when the lid body is opened for PCB board handling, reducing unnecessary moisture absorption and significantly extending the desiccant's lifespan.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] For an example, please refer to... Figures 1-4A moisture-proof storage device for PCB boards includes a storage box 1 and a box cover body 2 installed on the storage box 1. A cover plate 202 is fixedly installed on the box cover body 2. A cavity for placing desiccant is provided between the cover plate 202 and the box cover body 2. A plurality of control components are provided between the box cover body 2 and the cover plate 202. The control components are used to control the opening and closing of the cavity and the storage box 1.

[0032] The control component includes a rotating shaft 203 rotatably connected between the cover plate 202 and the box cover body 2 via a sealed bearing. The bottom end of the rotating shaft 203 is connected to a baffle 204 located below the box cover body 2. The baffle 204 has a plurality of second air ports 205. The bottom of the box cover body 2 has a plurality of first air ports 201. The number and position of the first air ports 201 correspond to the number and position of the second air ports 205.

[0033] Before the main body 2 of the box is opened, the baffle 204 is rotated to make the second air port 205 separate from the first air port 201, thereby sealing the cavity between the main body 2 of the box and the cover plate 202. This isolates the desiccant from the outside air when the main body 2 of the box is opened for PCB board loading and unloading operations, reducing unnecessary moisture absorption and thus significantly extending the service life of the desiccant.

[0034] Furthermore, such as Figure 1 and Figure 4 As shown, a turntable 206 is fixedly connected to the top of the rotating shaft 203. The turntable 206 contacts the top of the cover plate 202. The friction between the turntable 206 and the top of the cover plate 202 can limit the rotating shaft 203 and reduce the situation where the rotating shaft 203 rotates on its own.

[0035] Furthermore, such as Figure 1 and Figure 4 As shown, the cover plate 202 has a loading port 207, and a sealing cap 208 is threadedly connected to the inner wall of the loading port 207. The desiccant can be an existing bagged desiccant. The bagged desiccant is easy to put into the cavity from the loading port 207 or take out from the cavity. Rotating the sealing cap 208 separates the sealing cap 208 from the loading port 207, or the used desiccant in the cavity can be taken out from the loading port 207 and a new desiccant can be put in.

[0036] Furthermore, such as Figure 1 As shown, handles 3 are installed on the sealing cover 208, the turntable 206, and the box cover body 2. The handles 3 on the sealing cover 208 can facilitate the rotation of the sealing cover 208, the handles 3 on the turntable 206 can facilitate the rotation of the turntable 206, and the handles 3 on the box cover body 2 can facilitate the opening and closing of the box cover body 2.

[0037] Before opening the main body 2 of the box cover, first turn the handle 3 on the turntable 206 so that the turntable 206 drives the baffle 204 to rotate through the rotating shaft 203, so that the second air port 205 is misaligned with the first air port 201, and the first air port 201 is closed by the baffle 204. Then open the main body 2 of the box cover to take out and put in the PCB board. After the PCB board is taken out and put in, close the main body 2 of the box cover and rotate the turntable 206 in the opposite direction so that the second air port 205 is aligned and connected with the first air port 201, so that the desiccant can absorb the moisture in the storage box 1 through the first air port 201 and the second air port 205.

[0038] Furthermore, a hinge is provided between one side of the lid body 2 and the storage box 1, and a locking element is provided between the side of the lid body 2 away from the hinge and the storage box 1. The hinge is used to realize the rotational connection between the lid body 2 and the storage box 1.

[0039] Furthermore, such as Figure 1 As shown, the locking mechanism includes a latch 108 installed on the storage box 1 and a latch 109 installed on the box cover body 2. The latch 109 is connected to the latch 108, and the latch 109 and the latch 108 cooperate with each other to limit the box cover body 2 after it is closed.

[0040] Furthermore, such as Figure 2 As shown, a sealing gasket 4 is connected to the top of the storage box 1, and the sealing gasket 4 is in contact with the bottom of the box cover body 2. The sealing gasket 4 can improve the sealing between the storage box 1 and the box cover body 2.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, a hand-tightening bolt 107 is threadedly connected to the front of the storage box 1. One end of the hand-tightening bolt 107 extends into the storage box 1 and is rotatably connected to a sliding plate 104 via a bearing. Several second limiting brackets 105 are fixedly connected to the side of the sliding plate 104 away from the hand-tightening bolt 107. Several first limiting brackets 103 are fixed to the inner wall of the storage box 1 on the side away from the sliding plate 104. The positions of the first limiting brackets 103 correspond to the positions of the second limiting brackets 105. Both the first limiting frame 103 and the first limiting frame 103 are equipped with protective pads 106. By turning the hand-tightening bolt 107, the position of the second limiting frame 105 can be adjusted through the sliding plate 104. When the side of the PCB board is inserted into the protective pad 106, the second limiting frame 105 moves closer to the first limiting frame 103 to fix the PCB board and improve the stability of the PCB board during storage and overall movement. When the second limiting frame 105 moves away from the first limiting frame 103, the fixation can be released and the PCB board can be taken out.

[0042] Furthermore, the bottom of the second limiting frame 105 is slidably connected to the bottom of the inner cavity of the storage box 1 to prevent the second limiting frame 105 from rotating when the hand-tightening bolt 107 is turned.

[0043] Furthermore, such as Figure 3 As shown, a support plate 110 is installed inside the storage box 1. The support plate 110 is located between the first limiting frame 103 and the second limiting frame 105. The support plate 110 is used to support the PCB board to improve the stability of the PCB board.
