The working process of the invention is as follows:
the fire door to be detected is closed, at the moment, a detection person drives the detector body 11 to move to the closed position of the fire door or the closed position between two fire doors through the handheld rod 20, at the moment, the pressing plate 19 is pressed inwards, the pressing plate 19 overcomes the elastic action of the moving spring 18 to move inwards under the pressing action of the detection worker, at the moment, the moving pull rope 16 is connected with the clamping pull rope 15 to be loosened, at the moment, the clamping slide blocks 21 on the upper side and the

the detection worker supports against any position of the closed position of the fire door through the right end face of the detector body 11, at the moment, the rotating motor 46 is started, at the moment, the rotating motor 46 rotates and drives the rotating bevel gear 31 to rotate, at the moment, the rotating bevel gear 31 rotates and drives the meshing bevel gear 30 to rotate through gear meshing, at this time, the meshing bevel gear 30 drives the rotating fan 27 to rotate through the transmission of the rotating shaft 28, at this time, the rotating fan 27 rotates and sucks external air and inputs the air into the air pressure detection chamber 34 through the air inlet pipe 61, so that the air pressure in the air pressure detection chamber 34 is increased, at this time, the air pressure in the air pressure detection chamber 34 is detected through the air pressure detection plate 33, at the same time, the rotating motor 46 drives the centrifugal wheel 60 to rotate, at this time, the centrifugal wheel 60 rotates and increases the centrifugal force applied to the clutch slider 56, at this time, the clutch slider 56 moves outwards under the action of the centrifugal force against the elastic force of the clutch spring 54, at this time, the clutch slider 56 moves outwards and pushes the switching plate 58 to move upwards against the elastic force of the switching spring 57, at this time, the switching plate 58 moves upwards and pulls the upper and lower side switching pull ropes 59, at this time, the upper side switching pull ropes 59 move against the torsional spring 51 by connecting and pulling the rotating reel 52, at the moment, the rotating wire wheel 52 rotates and drives the overturning plate 43 to overturn into the overturning cavity 45 through the transmission of the overturning shaft 39, at the same time, the lower side switching pull rope 59 pulls the connecting pull rope to move, at the moment, the connecting pull rope pulls the connecting slide block to move leftwards by overcoming the elastic force of the connecting spring through connection, at the moment, the connecting slide block drives the closed ring 48 to move leftwards through fixed connection, when the air pressure detection plate 33 detects that the air pressure in the air pressure detection cavity 34 is stable, at the moment, the rotating motor 46 stops rotating, at the moment, the rotating fan 27 stops rotating and enables the centrifugal wheel 60 to stop rotating, at the moment, the centrifugal switching plate 58 resets under the elastic force of the switching spring 57, at the moment, the connecting slide block moves rightwards under the elastic force of the connecting spring, the connecting slide block moves to drive the closed ring 48 to move rightwards integrally and be attached to the detection surface, and reach stable closure through the surface with elasticity, and at the electromagnet is started and has magnetism, at the moment, the switch board overcomes the elastic action of the switch spring 63 to move leftwards under the pushing of the magnetic force of the electromagnet, the upper side and the lower side of the air inlet pipeline 61 are sealed, the effect of completely sealing the inside of the air pressure detection cavity 34 is further achieved, meanwhile, the rotating wire wheel 52 rotates and resets under the torsional elastic action of the torsion spring 51, at the moment, the rotating wire wheel 52 drives the overturning shaft 39 to rotate and reset through fixed connection, at the moment, the overturning plate 43 rotates to the vertical state and drives the supporting plate 41 to rotate to the vertical state, at the moment, the supporting plate 41 is abutted against the detection surface and plays a certain supporting effect, the detection stability performance of the device is further improved, at the moment, the air pressure is detected inside the air pressure detection cavity 34 through the air pressure detection board 33, if the air pressure is reduced, the gas loss inside the air pressure detection cavity 34 is proved, at the moment, the detection is carried out through the rotating speed detector 47, and if the detection fan 36 is pushed to rotate by the air flow, at this time, the detecting fan 36 rotates to drive the detecting shaft 37 to rotate and detect the rotating speed through the rotating speed detector 47, at this time, it can be judged that gas leakage needs to be detected again due to the fact that the sealing operation of the sealing ring 48 is not achieved optimally, on the contrary, a conclusion that the airtightness of the fire door is poor can be obtained, when the gas leakage needs to be detected again or the fire door needs to be detected again in the same place, the detector body 11 can be rotated, connected and supported through the rotating connecting plate 23, and further the detector body 11 is rotated conveniently for subsequent repeated detection, after the airtightness detection is completed, a detector can loosen and not press the pressing plate 19, at this time, the pressing plate 19 can be reset under the elastic force of the moving spring 18, at this time, the clamping springs 14 on the upper side and the lower side are reset under the pulling action of the clamping pull rope 15, at this time, the clamping slider 21 and the rotating connecting plate 23 are not clamped any more, then, the detector can pull the hand-holding rod 20 leftwards and pull the connecting plate 44 to move leftwards, at this time, the hand-holding rod 20 and the detector body 11 can be disconnected, at this time, the detector can re-install the clamping slider 44 into the air pressure detecting cavity 34, and drive the fixed sliding slider 21 to be aligned with the fixed pressing slider 32, and then the other end surface of the fire door to be opened, and the detector can be connected to the left-detecting temperature
