The keyhole seat 5 is fixed on the lintel beam 1, and the side surface of the lintel beam 1 is connected with an emergency door baffle 10. These are conventional structures and will not be described in detail herein.
Referring to fig. 2, the locking hole 12 of the locking hole seat 5 is a slot hole for allowing the rotating member to pass through. The keyhole seat 5 is also provided with an ear seat 13 which is convenient for installing the rotating shaft of the rotating part.
The middle section of the Z-shaped rotating plate 6 is provided with a rotating shaft 9, and the rotating shaft 9 is rotatably arranged on an ear seat 13. The Z-shaped rotating plate 6 can rotate around the axis of the rotating shaft 9, and the rotating shaft 9 is sleeved with a reset torsion spring 4 which applies downward acting force to the rotating section of the rotating part positioned on one side of the lock hole.
Referring to fig. 3, the length of the rotation section 14 of the "Z" shaped rotating plate 6 on the side of the locking hole is greater than the length of the rotation section 15 on the side of the locking signal output means. Thus, the gravity of the rotating section 14 located on the side of the lock hole is made larger than the gravity of the rotating section 15 located on the side of the locking signal output means, so that the "Z" -shaped rotating plate 6 rotates toward the side of the lock hole in a natural state.
The rotating section 14 of the Z-shaped rotating plate 6 at one side of the lock hole is provided with a limiting plate 11 which prevents the rotating section 14 from rotating downwards and passing through the lock hole. So that in a natural state, the rotating section 14 of the Z-shaped rotating plate 6 at one side of the lock hole is positioned to just cover the lock hole 12.
Referring to fig. 1 again, a travel switch bracket 3 is installed at the front end of the keyhole seat 5, and a travel switch 2 is installed in the travel switch bracket 3.
In the door opening state, the rotating section 14 of the Z-shaped rotating plate 6 on the lock hole side is positioned to just cover the lock hole 12. The front end of the rotating section 15 of the Z-shaped rotating plate 6 on the side of the locking signal output device is positioned right above the contact of the travel switch 2.
Referring to fig. 1 again, in the locking process that the lock pin 7 of the emergency door lock 8 is inserted into the lock hole 12, the lock pin 7 touches and drives the rear end of the Z-shaped rotating plate 6 to rotate, so that the front end of the Z-shaped rotating plate 6 triggers the contact of the travel switch 2, and the travel switch 2 sends a locking signal.
Of course, the travel switch may be replaced by a signal trigger switch such as a proximity switch or a photoelectric switch.
The emergency door lock with the locking signal output function in the embodiment solves the problem that in the prior art, a station control center receives a door closing signal of an emergency door, but the emergency door is only closed in place and is not locked, so that potential safety hazards exist; when the emergency door is locked, the platform control center receives the closing and locking signals of the emergency door.
Example 2
The emergency door lock with the locking signal output function comprises a lock hole seat with a lock hole and an emergency door lock fixed on an emergency door body, wherein a lock pin of the emergency door lock is inserted into the lock hole to complete locking. The keyhole seat is fixed on the door lintel beam, and the side surface of the door lintel beam is connected with an emergency door baffle. The lock hole on the lock hole seat is a slot hole for the convenience of the rotating piece to pass through. The keyhole seat is also provided with an ear seat which is convenient for installing a rotating shaft of the rotating part.
The above-described structures are the same as those in embodiment 1, and are not described in detail here.
The differences from example 1 are:
the ear seat is positioned at the front end of the keyhole seat.
Referring to fig. 4, the rotating member is a linear rotating plate 16. The length of the linear rotating plate on one side of the lock hole is larger than that on one side of the locking signal output device.
The middle section of the I-shaped rotating plate 16 is provided with a rotating shaft which is rotatably arranged on the ear seat. The linear rotating plate 16 can rotate around the axis of the rotating shaft, and a reset torsion spring which applies downward acting force to the rotating section of the rotating part positioned on one side of the lock hole is sleeved on the rotating shaft.
The rotating section 17 of the I-shaped rotating plate on one side of the lock hole is provided with a limiting plate 19 which prevents the rotating section from rotating downwards and passing through the lock hole. So that the rotating section of the I-shaped rotating plate 16 at one side of the lock hole is positioned to just cover the lock hole in a natural state.
The front end of the keyhole seat is provided with a travel switch bracket, and a travel switch is arranged in the travel switch bracket. In the state of opening the door, the rotating section 17 of the I-shaped rotating plate, which is positioned at one side of the lock hole, is positioned to just cover the lock hole. The front end of the rotating section 18 of the linear rotating plate on one side of the locking signal output device is positioned right above the contact of the travel switch 2.
The emergency door lock with the locking signal output function in the embodiment solves the problem that in the prior art, a station control center receives a door closing signal of an emergency door, but the emergency door is only closed in place and is not locked, so that potential safety hazards exist; when the emergency door is locked, the platform control center receives the closing and locking signals of the emergency door.
