[0036] Further, the limit switch 11 is arranged at the lower part of the first lock slot 3, the limit switch 11 detects whether the lock rod 15 is placed down, and the limit switch 11 sends the detected signal to the monitoring end of the elevator.

[0037] Further, the part of the limit switch 11 in contact with the first lock rod 5 is designed with elastic rubber.

[0038] Further, the limit switch 11 and the electromagnetic lock 7 are covered with a cover body for protecting the limit switch 11 and the electromagnetic lock 7.

[0039] Further, the mechanical lock 21 is also installed on the first left door lock plate 2, one end of the bracket 8 is connected to the first left door lock plate 2, and the other end is connected to the outside of the first lock slot 3, the mechanical lock 21 is installed on the bracket 8, and the mechanical lock 21 includes a lock hook 13, a lock tail 14, and a steel wire rope 20; the mass of the lock tail 14 is much greater than the mass of the lock hook 13, and the purpose of such design is mainly to make one end of the mechanical lock 21 heavy and the other end light; the lock hook 13 can be automatically raised under the action of the lock tail 14 and is inserted into the mechanical lock jack 5-2 after being raised; specifically, the lock hook 13 and the lock tail 14 of the mechanical lock are respectively connected to the bracket 8 through a pin shaft, the lock hook 13 can rotate relative to the bracket 8, and the rotation of the lock hook 13 is controlled by the lock tail 14 on one hand and by the steel wire rope 20 on the other hand; one end of the steel wire rope 20 is connected to the lock hook 13, and the other end of the steel wire rope 20 is connected to the handle 10 after winding around some steering wheels; the handle 10 can be placed on the second left door lock plate 17 on the other side of the floor door, and the operator can open the mechanical lock 21 by pulling the handle of the steel wire rope 20 at the back of the door; under normal circumstances, when the lock rod 5 falls into the lock slot 3, the lock hook 13 of the mechanical lock can be automatically inserted into the corresponding mechanical lock jack 5-2 on the lock rod 5; when the operator on the other side wants to open the already locked lock hook 3, the lock hook 13 can be separated from the mechanical lock jack 5-2 by pulling the handle of the steel wire rope 20, and the second level locking is formed by the above-mentioned mechanical lock in the embodiment.

[0040] Furthermore, the views of the second right door lock plate 16 and the second left door lock plate 17 on the rear side of the door are as follows: Figure 3 As shown, this is a rear view of the door lock; a second locking rod 19 is fixed on the second left door lock plate 17, and a second locking groove 18 is installed on the second left door lock plate 17, which is used to cooperate with the second locking rod 19; wherein, the first locking rod 5 and the second locking rod 19 are connected together by a connecting shaft 4, so that the two can rotate together, that is, when the first locking rod 5 is rotated on one side, the second locking rod 19 on the other side rotates together, which can open the door; furthermore, a handle 9 and a handle 12 are respectively installed on the first locking rod 5 and the first locking rod 19, and the operator can hold the handle to pull up the first locking rod 5 and the second locking rod 19.

[0041] Furthermore, the second lock groove 18, the second left door lock plate 17, the second lock rod 19, the first left door lock plate 2, and the first lock groove 3 are also provided with unlocking holes 23 located on the same axis. When an unlocking rod is inserted into the unlocking hole 23 on the back side of the door, the lock cylinder of the electromagnetic lock can be mechanically retracted. Specifically, the unlocking rod is inserted into the aforementioned unlocking hole 23, and can be inserted all the way to the location of the lock cylinder of the electromagnetic lock.

[0042] Furthermore, the first locking rod 5 and the second locking rod 19 are connected together by a connecting shaft 4. The connecting shaft starts from the side of the second locking rod 19 and passes through the second locking rod 19, the second right door lock plate 16, the first right door lock plate 1, and the first locking rod 5 in sequence. A shaft valve is installed on the shaft section between the first locking rod 5 and the first right door lock plate 1 to prevent the connecting shaft 4 from moving back and forth. After passing through the second locking rod 9, the connecting shaft 4 connects to the first locking rod 5. The position of the first locking rod 5 on the connecting shaft is controlled by another shaft valve. The position of the first locking rod 5 on the connecting shaft 4 can be adjusted by the shaft valve, that is, the distance between the first left door lock plate and the second left door lock plate can be adjusted to accommodate floor doors of different thicknesses.

[0043] The aforementioned shaft valve comprises two parts: the upper part is fixed on the first locking rod 5, and the lower part is fixed on the connecting shaft 4. When it is necessary to move the position of the first locking rod 5, the lower half of the shaft valve is first fixed on the connecting shaft 4 at the required position, and then the upper part of the first locking rod 5 is connected to the lower half, thereby realizing the position adjustment of the first locking rod 5 on the connecting shaft 4.

[0044] The specific usage method is as follows:

[0045] When the elevator does not reach the corresponding floor, the electromagnetic lock 7 keeps the door locked, and when the elevator reaches the floor, the electronic door is opened, the electromagnetic lock 7 receives the signal and keeps the unlocking (lock head retraction) state; then pull the wire rope handle outward, the lock hook 13 can be separated from the reserved hole of the first lock rod 5; finally, rotate the second lock rod 19 to separate the second lock rod 19 from the corresponding lock slot, and after the second lock rod 19 is taken away together with the second lock rod 5, the left and right doors of the corresponding floor are opened.

[0046] When the electromagnetic lock 7 is broken and cannot be normally opened, a mechanical unlocking method can be used to open the electromagnetic lock 7 by inserting an unlocking rod into the unlocking hole 23, which can be inserted into the position of the lock core of the electromagnetic lock 7 through the unlocking hole 23, and at the same time, the position of the first lock rod 5 can be detected in real time through the limit switch.

[0047] When the personnel enter the designated floor, the first lock rod 5 is manually rotated into the corresponding lock slot again, and then the electromagnetic lock 7 receives the door locking signal again to lock the first lock rod 5, and the mechanical lock 21 automatically locks the first lock rod 5.

[0048] Finally, it should be noted that the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.

[0049] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
