[0002] Automatic sealing and clamping devices are usually used in cabinets that require high sealing performance and safety, especially those cabinets that have special requirements such as waterproofing, dustproofing, and gas leakage prevention. For example, laboratory safety cabinets are used to store flammable, explosive or toxic substances such as chemicals and medicines. Cabinets need to have high sealing performance to prevent harmful gas leakage.
[0003] However, traditional clamping devices achieve sealing by applying pressure to make the sealing strip between the cabinet door and the cabinet fit tightly. However, the seals are easily worn during the process and may require more frequent maintenance and replacement. The sealing effect is easily affected by material deformation or wear, which may lead to the risk of leakage in the cabinet during long-term use.
[0004] Therefore, in order to solve the above problems, an automatic sealing and pressing device for an intelligent metal cabinet is proposed. Utility Model Content

[0006] In response to the problems existing in the prior art, the purpose of the present utility model is to provide an automatic sealing and clamping device for an intelligent metal cabinet. This solution can create a tighter seal by discharging the gas in the card groove, and is less dependent on the material of the sealing strip. Even if the sealing strip is worn, under the negative pressure state generated by the vacuum, the sealing strip can still be deformed and squeezed together, thereby achieving a good sealing effect and effectively extending the service life of the device.
[0007] 2. Technical solution

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.
[0034] Example:
[0035] See also Figure 1-3 , including a cabinet body 1 and a cabinet door 2. A snap-in groove 10 is provided at the edge of the cabinet body 1 near one end of the cabinet door 2. The snap-in groove 10 is arranged around the open end of the cabinet body 1. The cabinet door 2 is fixedly connected to one end of the cabinet body 1 with a snap-in block 9 matching the snap-in groove 10, and a pair of handles 4 are fixedly connected to the outer end of the cabinet door 2. The inner wall of the snap-in groove 10 and the outer end of the snap-in block 9 are covered with rubber pads. An air pump 3 is installed on the top of the cabinet body 1, and a flow channel is provided inside the cabinet body 1. The air pump 3 is connected to the flow channel. The inner wall of the snap-in groove 10 is provided with a plurality of air vents 11 connected to the flow channel.
[0036] Automatic sealing and clamping devices are usually used in cabinets that require high sealing performance and safety. However, traditional clamping devices achieve sealing by applying pressure to make the sealing strip between the cabinet door and the cabinet fit tightly. However, the seals are easily worn during the process and may require more frequent maintenance and replacement. The sealing effect is easily affected by material deformation or wear, which may lead to the risk of leakage in the cabinet during long-term use.
[0037] The air in the clamping groove 10 is sucked away by the air pump 3, so that a vacuum is formed between the clamping block 9 and the inner wall of the clamping groove 10. The negative pressure generated by the vacuum environment will force the clamping block 9 to further squeeze into the inside of the clamping groove 10, thereby enhancing the close fit between the cabinet 1 and the cabinet door 2 and continuously ensuring this close fit. Compared with the traditional pressing device, the present device can create a tighter seal by discharging the gas in the clamping groove 10, and is less dependent on the material of the sealing strip. Even if the sealing strip is worn, the sealing strip can still be deformed and squeezed together under the negative pressure state generated by the vacuum, thereby achieving a good sealing effect and effectively extending the service life of the device.
[0038] An air-blocking valve 7 is installed at the outer end of the cabinet 1 , and the air-blocking valve 7 is connected to the flow channel.
[0039] The air-locking valve 7 is a sealing valve that belongs to the existing technology. This valve is sealed under normal conditions, but the pressure can be released when the valve is turned. The air-locking valve 7 can ensure the sealing of the flow channel under normal conditions. When the user needs to open the cabinet 1, turning the switch on the air-locking valve 7 can allow outside air to enter the flow channel through the air-locking valve 7, thereby releasing the negative pressure state in the flow channel, and then the user can pull the handle 4 outward and open the cabinet 1.
[0040] See also Figure 2-3 One end of the cabinet body 1 close to the air-locking valve 7 is rotatably connected to a pair of rotating blocks 5, one end of the rotating block 5 is fixedly connected to a connecting rod 6, and the cabinet door 2 is slidably connected to the pair of connecting rods 6.
[0041] Through the structural design of this solution, the cabinet body 1 and the cabinet door 2 move towards each other in the same direction during the merging and separation process. The cabinet door 2 can slide on the connecting rod 6. After the connecting rod 6 is completely separated from the cabinet body 1, the user rotates the rotating block 5 to rotate the cabinet door 2 to one side of the cabinet body 1. With this arrangement, the snap-fit block 9 and the snap-fit groove 10 can fit together more tightly. This tight snap-fit can effectively reduce the gap and improve the sealing effect. The snap-fitting of the snap-fit block 9 and the snap-fit groove 10 moving towards each other will result in a more uniform pressure distribution around the joint. In comparison, the traditional rotating connection method may generate greater pressure at the contact point between the cabinet door 2 and the cabinet body 1, resulting in poor sealing effect at the joint.
[0042] See also Figure 3-6 A button 8 is installed at the outer end of the cabinet 1, and the button 8 is electrically connected to the air pump 3. The button 8 is arranged on the inner side of one of the rotating blocks 5. A limiting groove 13 is provided on the rotating block 5 located outside the button 8. A push rod 12 is slidably connected in the limiting groove 13. The push rod 12 matches the button 8. Both ends of the push rod 12 extend to the outside of the rotating block 5, and the material of the push rod 12 is set to metal. A plurality of magnets 14 are installed on the inner wall of the limiting groove 13 close to the button 8.
[0043] The push rod 12 is attracted by the magnet 14 and will stick to the inner wall of the limiting groove 13 close to the magnet 14. At this time, one end of the push rod 12 extends to the inner side of the rotating block 5. When the user rotates the rotating block 5 in an attempt to merge the cabinet body 1 and the cabinet door 2, the push rod 12 will squeeze the button 8. The button 8 is a push switch connected to the air pump 3. The principle of the button 8 is to control the on and off of the circuit through the mechanical structure of the button, and then control the start and stop of the air pump 3. When the button 8 is pressed, the mechanical structure inside the button will connect the electrical contacts at both ends of the button, closing the circuit. Through the closed circuit, the current flows through the button and enters the circuit of the air pump 3, starting the air pump 3. When the button 8 is released, the mechanical structure inside the button will disconnect the electrical contacts, disconnecting the air pump 3. Circuit, the circuit interruption causes the current to stop flowing to the air pump 3, and the air pump 3 stops working. Therefore, when the user rotates the rotating block 5 to make the rotating block 5 close to the outer end of the cabinet 1, the air pump 3 will start automatically. At this time, the user only needs to push the cabinet door 2 to merge it with the cabinet 1, and the air pump 3 will automatically draw out the air between the clamping block 9 and the clamping groove 10. When the user needs to open the cabinet door 2, first open the air closing valve 7 to release the negative pressure state in the clamping groove 10, and then pull the push rod 12 to the outside of the rotating block 5, so that the push rod 12 slides in the limit groove 13 and disengages from the magnet 14, and then the push rod 12 disengages from the button 8, thereby stopping the air pump 3. At this time, it will become easy for the user to open the cabinet door 2. Such a setting can improve the convenience of using this device.
[0044] Working principle:
[0045] When in use, the user first ensures that the air-closing valve 7 is in the closed state, and then rotates the rotating block 5 to drive the cabinet door 2 to rotate, so that the cabinet door 2 comes to the side of the open end of the cabinet body 1. At this time, the push rod 12 will squeeze the button 8, thereby starting the air pump 3. Then the user pushes the cabinet door 2 to merge with the cabinet door 2, and the clamping block 9 is clamped with the clamping groove 10, so that the cabinet door 2 is tightly attached to the open end of the cabinet body 1. The air pump 3 draws out the air in the flow channel, and then the air inside the clamping groove 10 also enters the flow channel through the vent 11 and is sucked away by the air pump 3, so that a pressure relief valve 2 is formed between the clamping block 9 and the inner wall of the clamping groove 10. Vacuum, the negative pressure generated by the vacuum environment will force the clamping block 9 to further squeeze into the inside of the clamping groove 10, thereby enhancing the close fit between the cabinet body 1 and the cabinet door 2, and continuously ensuring this close fit state. When the user needs to open the cabinet door 2, first open the air-closing valve 7 to allow outside air to enter the flow channel through the air-closing valve 7, thereby relieving the negative pressure state in the flow channel, and then pull the push rod 12 toward the outside of the rotating block 5 to disengage the push rod 12 from the magnet 14, and then make the push rod 12 slide in the limit groove 13 and disengage from the button 8, so that the air pump 3 stops working. At this time, it will become easy for the user to open the cabinet door 2.
[0046] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
