[0038] The rotating member 1 and the sensing member 2 are both arranged on the elevator landing door 3, the rotating member 1 has a first trigger part 11 and a second trigger part 12, the rotating member 1 can rotate in a first direction x under the action of external force, so as to drive the lock hook 41 of the landing door lock 4 to rotate, unlock the landing door lock 4, and trigger the sensing member 2 through the second trigger part 12, so as to send a signal to the main control module of the elevator.

[0039] Specifically, the landing door lock 4 can be arranged above the elevator landing door 3 as shown in Figure 1 The landing door lock 4 comprises a lock hook 41 and a hook block 42, wherein the lock hook 41 can be arranged on the door hanging plate 5 connected with the elevator landing door 3, and the hook block 42 can be arranged on the door machine bottom plate 6 connected with the door hanging plate 5. When the lock hook 41 is hooked with the hook block 42, the landing door lock 4 is locked, and the elevator landing door 3 is locked; when the lock hook 41 is separated from the hook block 42, the landing door lock 4 is unlocked, and the elevator landing door 3 is unlocked.

[0040] In actual application, when the staff needs to unlock the elevator landing door 3 to enter the elevator shaft, an external force is applied to the rotating member 1, so that the rotating member 1 rotates in the first direction x, the first trigger part 11 of the rotating member 1 directly or indirectly contacts the lock hook 41 of the landing door lock 4, thereby driving the lock hook 41 to rotate, so that the lock hook 41 is separated from the hook block 42, the landing door lock 4 is unlocked, and the elevator landing door 3 is unlocked. At the same time, the second trigger part 12 of the rotating member 1 triggers the sensing member 2, and the sensing member 2 sends a signal to the main control module of the elevator, so that the main control module controls the elevator car to stop running, or controls the elevator car not to move to the floor where the current opened landing door is located.

[0041] Understandably, the utility model discloses can realize the unlocking of elevator floor door 3 based on the rotation of rotating part 1, and rotating part 1 unlocks elevator floor door 3 simultaneously, and will also trigger sensing part 2, make sensing part 2 send signal to the main control module of elevator, to make elevator take corresponding braking measure. Therefore, the utility model further increases the unlocking verification mechanism based on sensing part 2 on the unlocking verification mechanism of floor door lock 4 itself, when the unlocking verification mechanism of floor door lock 4 itself is invalid, still can open the floor door through sensing part 2 to sensing, thereby control the operation of elevator car, and the use safety of elevator is improved significantly.

[0042] Optionally, sensing part 2 can send signal to the main control module of elevator through wired transmission, also can send signal to the main control module of elevator through wireless transmission.

[0043] In one embodiment, the hook 41 is provided with a transmission member 7, and the end of the transmission member 7 away from the hook 41 is formed with a contact portion 71. The first trigger portion 11, the contact portion 71, the second trigger portion 12 and the sensing part 2 are sequentially arranged along the first direction x. Thus, when the rotating part 1 rotates along the first direction x, the first trigger portion 11 gradually approaches the contact portion 71, and the second trigger portion 12 gradually approaches the sensing part 2. When the first trigger portion 11 of the rotating part 1 contacts and pushes the contact portion 71, the second trigger portion 12 triggers the sensing part 2, at this time, the transmission member 7 is pushed to drive the hook 41 to rotate, the floor door lock 4 is unlocked, and the sensing part 2 sends a signal to the main control module of the elevator.

[0044] Exemplarily, the transmission member 7 can be an unlocking plate, one end of the unlocking plate is fixedly connected with the hook 41 by bolts, and the contact portion 71 includes an abutting plate arranged at the end of the unlocking plate away from the hook 41. For specific structure, please refer to Figure 1 When the rotating part 1 rotates along the first direction x, the first trigger portion 11 abuts against and pushes the bottom of the abutting plate, and then the transmission member 7 is lifted upward, so that the transmission member 7 drives the hook 41 to rotate, the hook 41 is separated from the hook block 42, and the floor door lock 4 is unlocked.

[0045] In this embodiment, since the rotating part 1 indirectly drives the hook 41 to rotate through the transmission member 7, the rotating part 1 does not need to directly contact the hook 41, so the structural complexity of the rotating part 1 can be reduced. In addition, the first trigger portion 11, the contact portion 71, the second trigger portion 12 and the sensing part 2 are sequentially arranged along the first direction x, which improves the compactness of the device structure and makes the device structure more simple.

[0046] In one embodiment, please refer to Figure 1 , 3, 4, the rotating member 1 is fixedly provided with a rotating shaft 8, the rotating member 1 is rotatably connected to the elevator landing door 3 through the rotating shaft 8, and an end of the rotating shaft 8 away from the rotating member 1 penetrates through the elevator landing door 3 and is exposed on a side of the elevator landing door 3 away from the rotating member 1.

[0047] Specifically, the circumferential direction of the rotating shaft 8 coincides with the first direction x, and the first direction x is a fixed direction of surrounding along the circumferential direction of the rotating shaft 8.

[0048] Exemplarily, the cross section of the end of the rotating shaft 8 away from the rotating member 1 can be non-circular, including but not limited to triangular, rectangular, elliptical and the like. The side of the elevator landing door 3 away from the rotating member 1 can be provided with an unlocking slot 31, and the end of the rotating shaft 8 away from the rotating member 1 is located in the unlocking slot 31. The unlocking slot 31 is used for inserting a key (not shown in the figure), and the key is matched with the shape of the end of the rotating shaft 8 away from the rotating member 1, so that after being inserted into the unlocking slot 31, the rotating shaft 8 can be rotated by the rotation of the key, and then the rotating member 1 is driven to rotate.

[0049] In the embodiment, the staff can rotate the rotating shaft 8 on the side of the elevator landing door 3 away from the rotating member 1, thereby driving the rotating member 1 to rotate, which is convenient to use and good in experience.

[0050] In one specific embodiment, referring again to Figure 1 , the rotating member 1 is further used for rotating along the second direction y under the action of an external force, so that the second trigger part 12 abuts against the top of the contact part 71 and the lock hook 41 of the landing door lock 4 is reset by the transmission member 7, thereby locking the landing door lock 4.

[0051] Specifically, the second direction y is the opposite direction of the first direction x. When the rotating member 1 rotates along the second direction y, the abutment of the first trigger part 11 and the contact part 71 is released, the second trigger part 12 gradually approaches the contact part 71, and finally abuts against the top of the contact part 71, so that the lock hook 41 is reset by the transmission member 7, thereby locking the landing door lock 4.

[0052] It can be understood that in the embodiment, the locking of the landing door lock 4 can be realized by rotating the rotating member 1 along the second direction y, which can effectively reduce the risk of accidental opening of the elevator landing door 3.
