[0017] Specifically, the worm gear 5 is driven to rotate by the torsion member 4 on the mounting base 2 of the main door frame 1. The worm gear 5 meshes with and drives the worm wheel 6 and the gear plate 7 to rotate synchronously. The gear plate 7 further meshes with and drives the two rack plates 8 to slide in opposite directions in a straight line, so that the shaft 9 on the rack plate 8 slides along the mounting base 2 and achieves rotational engagement with the kit 10 of the inspection door body 3. At the same time, relying on the self-locking characteristics of the worm gear 5 and worm wheel 6 and the precise meshing of the rack of the gear plate 7, the structural stability and sealing reliability of the inspection door after connection are ensured.

[0019] Specifically, the rotating handle of the operating torsion member 4 drives the shaft 9, which is rotatably connected to the mounting base 2, to rotate. This, in turn, drives the worm 5, which is fixedly sleeved on the outer surface of the shaft 9, to rotate synchronously. The worm 5 meshes with the transmission worm wheel 6 and the coaxially fixed gear plate 7. The gear plate 7 then meshes with and drives the two rack plates 8 to slide in opposite directions along the sliding grooves built into the mounting base 2. This causes the shaft 9, which is fixed to the rack plate 8 at the end away from the gear plate 7, to slide synchronously with the rack plate 8 and form a stable rotational engagement with the kit 10 of the inspection door body 3.
