Description

Technical Field

[0001] The utility model relates to the technical field of protective sealing doors, and more specifically, to a rapidly deployable protective sealing door. Background Art

[0002] The protective sealed door is a specially designed door, mainly used to prevent harmful substances from entering a specific area and protect the safety of personnel and equipment. It is usually installed in laboratories, hospitals, factories or other places where the environment needs to be controlled. The main function of the protective sealed door is to block shock waves, meet the corresponding resistance requirements, and can block the spread of toxic gases and other harmful substances.

[0003] In order to provide higher security, the protective sealed doors currently on the market may sacrifice the speed of opening and closing the doors. Protective sealed doors are often equipped with complex mechanical locking systems to ensure that they can remain closed under extreme conditions. These systems may include multi-point locking mechanisms, automatic locking devices, etc. The operations of opening and closing protective sealed doors are mostly cumbersome, resulting in a poor user experience. The operations of opening and closing protective sealed doors may require certain training and practice to master. If the operator is not familiar with the operating procedures, the time required for opening and locking will be long, which will consume physical strength. In addition, if the operation is incorrect, the locking purpose may not be achieved, resulting in a poor sealing effect of the entire protective sealed door.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a rapidly deployable protective sealing door. Utility Model Content

[0009] Preferably, the connection point where one end of the No. 1 rod and one end of the No. 2 rod are rotatably connected to the top of the frame is located in the middle of the top of the frame, and the connection point where the other end of the No. 3 rod is rotatably connected to the top of the sealing door is located in the middle of the top of the sealing door, and the length of the rack is equal to half the circumference of the gear, ensuring that the sealing door can be fully opened or closed.

[0010] Preferably, two rollers for flexibly moving the sealing door are provided at the bottom of the sealing door to facilitate the opening and closing of the sealing door.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, by setting the gear, the cylinder piston rod extends out, the rack drives the gear to rotate counterclockwise, the No. 1 rod, the No. 2 rod and the No. 3 rod rotate counterclockwise, the sealed door opens, the cylinder piston rod retracts, the rack drives the gear to rotate clockwise, the No. 1 rod, the No. 2 rod and the No. 3 rod rotate clockwise, and the sealed door closes, thereby achieving the technical effect of quickly and simply opening and closing the sealed door, thereby solving the problem that most of the operations of opening and closing the protective sealed door in the prior art are cumbersome, and the operation of opening and closing the protective sealed door may require certain training and practice to be proficiently mastered. If the operator is not familiar with the operation process, the time required for opening and locking is relatively long, and the locking purpose may not be achieved when the operation is incorrect, thereby causing the sealing effect of the entire protective sealed door to deteriorate.

[0014] 2. In the utility model, by arranging rollers at the bottom of the sealing door, the technical effect of flexibly moving the sealing door is achieved, thereby solving the problem of the sealing door being difficult to move and inconvenient to open and close in the prior art.
