[0002] Air defense doors are civil defense protection equipment. After installation, they need to ensure their tightness and meet the requirements of protection and sealing functions. Therefore, they need to be tested for tightness before leaving the factory. Testing their air leakage is an important indicator for evaluating the performance of air defense doors.
[0003] At present, when inspecting civil air defense doors, it is generally necessary to inspect multiple sets of data such as verticality, sealing and stability. When conducting sealing inspection, water is generally sprayed on the edge of the civil air defense door for inspection. This kind of inspection not only wastes water resources, but also has poor inspection quality. Moreover, during the long-term use of civil air defense doors, its simple preliminary quality inspection cannot guarantee the quality problems in the subsequent use. Therefore, a civil air defense inspection door is proposed to address the above problems. Utility Model Content

[0010] At present, when testing civil air defense doors, it is generally necessary to test multiple sets of data such as their verticality, sealing and stability. When performing sealing tests, water is generally sprayed on the edges of the civil air defense doors for testing. This type of testing not only wastes water resources, but also has poor testing quality. Moreover, during the long-term use of civil air defense doors, the simple preliminary quality test cannot guarantee the quality problems during subsequent use. During the use of this device, the door leaf rotates and cooperates with the door frame. The double-output shaft motor is started to drive the threaded shaft to rotate, and the threaded shaft drives the moving sleeve to rotate. The moving sleeve drives the push rod to move. At this time, the push rod drives the push plate to squeeze the airbag, and the internal air of the airbag is discharged into the airway through the exhaust pipe, and directly contacts the inner wall of the door frame through the exhaust hole. At this time, when the pressure value of the air pressure sensor remains unchanged for a long time, it means that it is well sealed. Once the pressure sensor value continues to decrease, a signal can be sent to the external controller and alarm to remind the staff to perform maintenance. At this time, the sealing of the equipment can be continuously tested by this device to ensure the quality of the civil air defense door.
[0011] As an optional solution of the civil air defense detection door described in the utility model, an air pressure sensor is also installed on the outside of the airbag, the bottom of the airbag is connected to an air inlet pipe, and a one-way valve is installed on the outside of the air inlet pipe.
[0012] The two sides of the airbag are fixedly connected to the limit frame and the push plate, which makes it convenient for the airbag to be squeezed and stretched. At the same time, the setting of the one-way valve makes it convenient for the air intake pipe to inflate the airbag when it is reset.
[0013] As an optional solution for the civil defense detection door described in the utility model, wherein: a first gear plate is also fixedly connected to one side of the movable sleeve, a transition gear is meshed on the top of the first gear plate, the interior of the transition gear is rotationally connected to the installation frame through a rotating shaft, a rotating gear is meshed on the outside of the transition gear, the interior of the rotating gear is fixedly connected to a rotating shaft, and both ends of the rotating shaft are rotationally connected to the installation frame.

[0015] When the movable sleeve moves, the movable sleeve drives the first gear plate to move, the first gear plate drives the transition gear to rotate, the transition gear drives the rotating gear to move, and the rotating gear drives the rotating shaft to rotate, thereby causing another rotating gear to rotate, so that the rotating gear drives the second gear plate to move, and then the second gear plate drives the limiting plate below to engage with the top of the door leaf, thereby further fixing the door leaf and ensuring the stability of the door leaf.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] During use, the utility model rotates the door leaf and cooperates with the door frame, starts the double-output shaft motor to drive the threaded shaft to rotate, and the threaded shaft drives the moving sleeve to rotate, and the moving sleeve drives the push rod to move. At this time, the push rod drives the push plate to squeeze the airbag, and the internal air of the airbag is discharged into the airway through the exhaust pipe, and directly contacts the inner wall of the door frame through the exhaust hole. When the pressure of the air pressure sensor remains unchanged for a long time, it indicates that the air pressure is well sealed. Once the value of the air pressure sensor continues to decrease, a signal can be sent to the external controller and the alarm to remind the staff to perform maintenance. At this time, the sealing of the equipment can be continuously detected by this device to ensure the quality of the civil air defense door.
[0018] When the movable sleeve moves, the movable sleeve drives the first gear plate to move, the first gear plate drives the transition gear to rotate, the transition gear drives the rotating gear to move, and the rotating gear drives the rotating shaft to rotate, thereby causing another rotating gear to rotate, thereby moving the second gear plate, and then causing the second gear plate to drive the limiting plate below to engage with the top of the door leaf, thereby further fixing the door leaf and ensuring the stability of the door leaf.
