Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a civil air defense door capable of monitoring an explosion-proof locking state. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. There are distinct classifications of civil defense doors, including ordinary single-leaf and double-leaf protective closed doors and closed doors, single-leaf and double-leaf protective closed doors and closed doors with movable thresholds, and other civil defense equipment. Under normal circumstances, civil defense doors are in a locked state, and the material of civil defense doors is relatively thick, which can achieve an explosion-proof effect.

[0003] However, during use, the civil air defense door can only play a safety and explosion-proof role when it is locked, and the normal locked state is an important indicator for safety inspection. Therefore, monitoring probes are often installed to monitor the locked state of the civil air defense door. However, once the lock body is opened, it is necessary to close it manually. Once a dangerous situation occurs during this process, it will cause serious casualties due to the civil air defense door not being in a locked state, which is very dangerous. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that during use, the civil air defense door can only play a safety and explosion-proof role when it is in the locked state, and the normal locked state is an important indicator for safety inspection. Therefore, a monitoring probe is often equipped to monitor the locked state of the civil air defense door. However, once the lock body is opened, it is necessary to go forward to close it manually.

[0019] In summary, the beneficial effects of the utility model are:

[0020] 1. By setting up an adjustable locking device, when the operating lever drives the first gear to rotate, it can cooperate with the rack plate to drive the rectangular block to move, and then it can be fixed with the rectangular slot. This is in a locked state. When it is found that it is not in a locked state, the drive motor connected to the external console through the Internet is controlled at this time, so that the half-tooth gear can be driven to rotate, and then the second gear can be used to drive the operating lever to rotate, so that it is in a locked state. No special person is required to be present for operation. Since the main control of the civil air defense door must be purely mechanical control to avoid power outage and inability to control, the non-meshing part at the bottom of the half-tooth gear rotates one circle to the top of the second gear, which will not affect the control of the operating lever.

[0021] 2. By setting up an auxiliary locking device, the sliding block can drive the locking rod to move, so that the locking rod can be locked into the locking hole, so that the operating rod can be fixed inside, and then during the civil defense and explosion-proof process, it cannot be opened from the outside, thereby increasing the overall safety.

[0028] The specific settings and functions of the regulating locking device 7 and the auxiliary locking device 8 are described in detail below.

[0029] Reference Figure 2 and Figure 3When the locking cam 75 is in the state of being moved, the locking cam 71 is in the state of being moved along the cam 74, and the cam 73 is in the state of being moved along the cam 74. When the locking cam 75 is in the state of being moved, the cam 73 is in the state of being moved along the cam 74. A driving motor 79 is fixedly installed on one side of the first door body 4, and a rotating rod 710 is fixedly connected to the output end of the driving motor 79, and one end of the rotating rod 710 is fixedly connected to a half-tooth gear 711. The outer surface of the operating rod 72 is located on one side of the half-tooth gear 711 and is fixedly connected to the second gear 712. By setting the rotating rod 710 and the half-tooth gear 711, the rotating rod 710 drives the meshing surface of the half-tooth gear 711 to mesh with the second gear 712 to play a role. When the non-meshing surface is rotated to be located above the second gear 712, it can avoid affecting the operation of the operating rod 72. A rectangular slot 713 is opened on one side of the second door body 5, and a rectangular block 78 is fixedly connected to one side of the rack plate 77. The rectangular block 78 can be stuck into the inner wall of the rectangular slot 713. By setting the rectangular block 78 and the rectangular slot 713, the first door body 4 and the second door body 5 can be in a locked state.

[0030] Reference Figure 4 As shown, in this embodiment: the auxiliary locking device 8 includes a rectangular frame 81, one side of the outer surface of the rectangular frame 81 is fixedly connected to one side of the outer surface of the second door body 5, the inner wall of the rectangular frame 81 is slidably connected with a sliding block 82, and one side of the outer surface of the sliding block 82 is fixedly connected with an auxiliary rod 83.
