[0020] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0021] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0022] One of the preferred embodiments of the present application is as follows: Figures 1 to 4 As shown, a sealing beam structure for protecting a closed door comprises a door frame 1 and a door body 2 rotatably mounted on one side of the door frame 1; a locking assembly 21 is arranged on the side of the door body 2, and the locking assembly 21 can lock the door body 2 after closing; a sealing assembly 22 is arranged on the side of the door frame 1, and the sealing assembly 22 can seal the gap between the door body 2 and the door frame 1, and the locking assembly 21 and the sealing assembly 22 cooperate with each other through a driving structure 11; when sealing, the door body 2 rotates into the door frame 1, and then the locking assembly 21 is driven to drive the sealing assembly 22 to seal the door body 2 and the door frame 1 through the driving structure 11, and then the locking assembly 21 is driven until the locking assembly 21 is engaged and locked with the side of the door frame 1, and then the door body 2 is locked and sealed. The structure is simple and easy to operate, and the sealing effect is good, which is convenient for reducing emergency operation time and improving the safe living environment for personnel.

[0023] In this embodiment, Figure 1 and Figure 2As shown, an installation groove is opened on the side of the door frame 1, and the installation groove is provided to install the sealing assembly 22. The sealing assembly 22 includes a sealing beam body 221 that is limitedly slidably installed on the side of the door body 2, and a sealing block 222 that is elastically installed in the installation groove by a spring; when sealing is performed, the locking assembly 21 moves to drive the sealing beam body 221 to move upward to extend into the installation groove to squeeze the sealing block 222, thereby facilitating better sealing and having strong practicality.

[0024] It should be known that a groove slightly higher than the door body 2 is provided on the side where the door frame 1 and the door body 2 are rotatably connected. Under normal conditions, the sealing block 222 is flush with the top of the door body 2 under the elastic limit of the spring, and the sealing beam 221 is driven by the locking assembly 11 so that the top of the sealing beam 221 and the top of the door body 2 are in the same horizontal plane, thereby preventing the sealing assembly 22 from interfering with the door body 2 when the door body 2 is opened. When the door body 2 is opened to the extreme position, the sealing beam 221 at this time moves into the groove along with the door body 2, thereby preventing the sealing beam 221 from causing interference.

[0025] In this embodiment, Figure 1 and Figure 2 As shown, it should be known that in order to allow the sealing beam 221 to move up and down stably, a limit groove perpendicular to the ground is opened on the side of the door body 2, and a limit block slidably installed in the limit groove is installed on the side of the sealing beam 221, so that the limit block can slide in the limit groove to stably drive the sealing beam 221 to slide stably and seal the gap, which is simple to operate and has a good sealing effect.

[0026] In this embodiment, Figures 2 to 4 As shown, the locking assembly 21 includes a locking block 211 limitedly installed on the side of the door body 2, and a locking groove 212 opened on the side of the door frame 1; the locking block 211 matches the locking groove 212; when locking, the locking block 211 moves in a direction parallel to the ground, and then the locking block 211 can be smoothly inserted into the locking groove 212 for engagement and locking, thereby facilitating better and safe locking of the door body 2, simple operation, and ensuring personnel safety.

[0027] In this embodiment, Figures 2 to 4 As shown, it should be known that in order to make the locking block 211 slide steadily, a limiting rod parallel to the ground is provided on the side of the door body 2, and the locking block 211 is sleeved on the outside of the limiting rod, so that the locking block 211 can slide back and forth steadily along the limiting rod, thereby facilitating better locking or opening.

[0028] In this embodiment, Figures 2 to 4As shown, it can be understood that the driving structure 11 includes mounting blocks 111 respectively arranged on the sides of the sealing beam body 221 and the locking block 211, and the same driving rod 112 hinged to the two mounting blocks 111; when sealing is performed, the locking block 211 can be driven to slide along the direction of the limit rod, and when the locking block 211 slides, the sealing beam body 221 can be driven to move upward through the driving rod 112 to elastically squeeze the sealing block 222, and then when the angle between the driving rod 112 and the travel direction is 90°, the upward movement distance of the sealing beam body 221 is the largest, and then the sealing block 222 is squeezed to the maximum force, and at this time, when the locking When the stop block 211 continues to slide, the angle between the driving rod 112 and the travel direction is greater than 90°, so that the sealing block 222 is elastically reset to squeeze the sealing beam 221 and move down until the locking block 211 extends into the locking groove 212 to engage, so that the driving rod 112 provides the locking block 211 with a force in the same direction of travel, which is convenient for better locking and fixing the locking block 211. At the same time, the sealing block 222 fits tightly with the sealing beam 221 to block the gap, and then seals while locking, reducing the emergency operation time, and performing faster and better closing and sealing protection, thereby ensuring the physical and mental safety of personnel to the greatest extent.

[0029] In this embodiment, Figure 1 As shown, it can be understood that a handle 12 is installed on the side of the locking block 211, so that the locking block 211 can be better driven by the handle 12, and the operation is convenient.

[0030] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
