When a user performs a closing operation on the inner side of the civil air defense door, after the civil air defense door 12 moves to the closing position in a transverse direction, and at this time, the inward pushing shaft 43 and the outward pushing shaft 21 are in the unlocking state shown in fig. 11, firstly, the folding handle 25 is rotated clockwise in the direction shown in fig. 11, the cam 55 is rotated synchronously until one end with a large diameter is rotated to be separated from the locking rod 28, the baffle 50 is pushed to be close to the buckle cover 29 under the elastic force of the spring 51, the whole locking rod 28 is moved to the right in the direction shown in fig. 11 for a certain distance, as shown in fig. 12, the locking rod 28 which is moved to the right no longer presses the locking block 53, the locking block 53 is rotated clockwise into the locking groove 54 under the elastic force of the torsion spring 52, at this time, the inward pushing shaft 43 and the outward pushing shaft 21 are in a mutually locking state and can be moved axially together, and then, the outward pushing shaft 21 is moved, the polygon prism 48 is separated from the locking block 49, the outer pushing shaft 21 and the inner pushing shaft 43 can rotate freely, then the folding handle 25 is rotated to drive the outer pushing shaft 21, the inner pushing shaft 43, the first bevel gear 32 and the second bevel gear 36 which are engaged with each other, the inner pushing transmission shaft 31 and the swing arm 46 to rotate, further the shifting block 45 is driven to rotate to be close to the guide convex rib 44, because the guide convex rib 44 is fixed, the shifting block 45 drives the inner pushing transmission shaft 31 and the civil air defense door leaf 12 to move longitudinally into the civil air defense door frame in the process of rotating to be close to the guide convex rib 44, and the sealing operation is completed, in the operation process, the hand of an operator applies a horizontal leftward force in the direction shown in fig. 12 to the folding handle 25 while rotating, and the first bevel gear 32 and the second bevel gear 36 are ensured to be always engaged with each other. After the civil air defense door 12 is closed, the folding handle 25 is pulled to move rightwards in the direction shown in fig. 12, the second bevel gear 36 is separated from the first bevel gear 32, the third bevel gear 37 is meshed with the first bevel gear 32, at the moment, the polygon prism 48 extends into the polygon hole 42 in the locking block 49 to be in inserting fit, then, the folding handle 25 is rotated anticlockwise, the large-diameter end of the cam 55 is rotated to the locking rod 28, the locking rod 28 is integrally moved leftwards, the locking rod 28 moved leftwards pushes the locking block 53 to be rotated anticlockwise to be separated from the locking groove 54, the state is restored to the state shown in fig. 11, and the inner pushing shaft 43 and the outer pushing shaft 21 are unlocked. After that, the inward pushing shaft 43 and the inward pushing transmission shaft 31 do not rotate any more, and then the stirring block 45 and the swing arm 46 are locked, so that the sealing property between the civil air defense door leaf 12 and the civil air defense door frame is ensured, and the civil air defense door leaf 12 is prevented from being easily separated from the installation groove 15. Wherein the inner push shaft 43 and the outer push shaft 21 are no longer locked, the inner push shaft 43 can be axially moved alone so that an operator outside the security door can open the security door leaf 12 outside after the closing operation is performed inside.
When the user performs the opening operation at the inner side of the door, the same operation as the opening operation at the outer side of the door is performed except that the direction in which the folding handle 25 is rotated is reversed.
Further, in order to prevent the square rail 9 from getting into the gap between the adjacent bearing sets when moving laterally on the traverse bearing set 7 and the longitudinal bearing set 8, as shown in fig. 3, a horizontally arranged vertical plate 16 is installed in the traverse sliding groove 5 and the longitudinal sliding groove 6, the vertical plate 16 passes through the traverse bearing set 7 and the longitudinal bearing set 8, and the height of the vertical plate 16 is lower than the height of the traverse bearing set 7 and the longitudinal bearing set 8, so as to support the square rail 9 to a certain extent.
In order to avoid the above situation, as the toggle block 45 rotates to approach the guide rib 44, because the toggle block 45 moves along an arc-shaped path at one end, a transverse component force is generated when contacting the guide rib 44, so that when the civil air defense door 12 is pushed to move longitudinally, the transverse component force may cause the civil air defense door 12 reaching the closed position to move transversely, and further, accurate sealing closure cannot be performed, as shown in fig. 9, two sets of pushing-in transmission shafts 31 are installed in the civil air defense door 12, wherein a first bevel gear 32 at the bottom end of one set of pushing-in transmission shafts 31 can be engaged with a second bevel gear 36 on the pushing-in shaft 43, a second bevel gear 36 engaged with the first bevel gear 32 at the bottom end of the other set of pushing-in transmission shafts 31 is installed on the inner wall of the civil air defense door 12, and the second bevel gears 36 at both sides are connected by a transmission device, the transmission device comprises a transmission rod 38, the drive rod 38 is provided with fourth bevel gears 39 at each end, the fourth bevel gears 39 being capable of meshing with the second bevel gears 36 on each side. When transmission is carried out, the two groups of pushing transmission shafts 31 rotate reversely, the shifting blocks 45 on one sides of the two groups of pushing transmission shafts rotate synchronously, after the two groups of shifting blocks 45 rotate reversely and approach the guide convex ribs 44, transverse component forces generated by the two groups of shifting blocks are mutually offset, and only the anti-man door leaf 12 is driven to move longitudinally, so that the accuracy of the sealing and closing position is ensured.
Further, in order to facilitate opening and closing operations inside the civil air defense door, as shown in fig. 10, the folding handle 25 includes a first handle 251 hinged to the outward pushing shaft 21, the first handle 251 is provided with a first through groove 255, a second handle 252 is hinged in the first through groove 255, a second through groove 253 is provided on the second handle 252, and a third handle 254 is hinged in the second through groove 253, as shown in fig. 12, the third handle 254 can rotate to a position parallel to the first handle 251 so as to rotate the outward pushing shaft 21. The third handle 254 can be folded into the second handle 252, and the second handle 252 can be folded into the first handle 251, so that the overall folding handle 25 has a smaller volume and is convenient to fold and accommodate into the side wall of the civil air defense door 12.
Further, a grouting pipe 56 is installed on the side wall of the civil air defense door leaf 12, one end of the grouting pipe 56 penetrates through the side wall of the civil air defense door leaf 12 to be communicated with the cavity inside the civil air defense door leaf 12, and the other end of the grouting pipe 56 is located on the outer side of the civil air defense door leaf 12 and is provided with a sealing cover 57. Under the emergency situation in wartime, when the user needs to seal the civil air defense sealing door permanently, the concrete can be poured into the interior of the civil air defense door leaf 12 through the grouting pipe 56, so that the civil air defense door leaf 12 is utilized to seal the door opening of the civil air defense sealing door permanently, and the sealing cover 57 can prevent dust or other impurities from entering the civil air defense door leaf 12 to influence the normal use of the bidirectional door opening and closing device when the grouting pipe 56 is in an unused state.
The technical solution of the present invention is not limited to the scope of the embodiments of the present invention. The technical contents not described in detail in the present invention are all known techniques.
