[0047] Currently, when an elevator breaks down in an area that is not level or stalls due to a power outage, passengers in the car may panic and try to open the car door themselves to seek an escape route. In this case, passengers often cannot accurately determine the specific location of the car, and there may be a certain height difference between the car and the floor plane. Therefore, even if the passengers can successfully leave the car, they may be injured due to this height difference.
[0048] Based on this, this embodiment provides an anti-pick door protection device, such as Figure 1-10 As shown, the anti-pick door protection device includes a lock hook assembly 3 and a lock hook seat 4, the lock hook assembly 3 is arranged on the door machine bottom plate 1, and the lock hook seat 4 is arranged on the door knife bottom plate 2;
[0049] The lock hook assembly 3 includes a base 31, a movable base 32 and a lock hook 33. The base 31 is arranged on the door machine bottom plate 1, the movable base 32 is movably arranged on the base 31, the lock hook 33 is rotatably arranged on the movable base 32, and the lock hook 33 has a locking position relative to the lock hook base 4 and an unlocking position relative to the lock hook base 4.
[0050] An elastic member 34 is provided between the base 31 and the movable seat 32. The elastic member 34 is used to enable the movable seat 32 to drive the lock hook 33 to move relative to the base 31 so that the lock hook 33 contacts the striker plate 5. The lock hook 33 is used to rotate relative to the movable seat 32 under the joint action of the elastic member 34 and the striker plate 5, and switch from a locked position to an unlocked position.
[0051] Specifically, the elastic member 34 releases elastic potential energy to drive the moving seat 32 and the locking hook 33 to move relative to the base 31. When the elevator is located in the leveling area, Figure 7-8 As shown, the lock hook 33 contacts the striker plate 5 under the action of the elastic member 34; and the elastic member 34 continues to release elastic potential energy, the lock hook 33 rotates under the action of the elastic member 34 and the striker plate 5, and switches from the locked position to the unlocked position, at which time the lock hook 33 unlocks the lock hook seat 4. When the elevator is located in a non-level area, such as Figure 9-10 As shown, the lock hook 33 cannot contact the striker plate 5 , so the lock hook 33 is maintained in the locked position, and the lock hook 33 locks the lock hook seat 4 .
[0052] Specifically, the elastic member 34 includes a spring, but is not limited thereto.
[0053] The anti-door prying protection device provided in this embodiment can prevent passengers from prying the door to save themselves when the elevator car is not leveled, thereby avoiding the dangerous situation of falling into the shaft, and improving the safety of the elevator. At the same time, it can effectively prevent passengers (especially children) from prying open the elevator door, thereby reducing the risk of abnormal opening of the elevator door due to external interference and protecting passengers from accidental injuries. It can also ensure that the elevator door remains locked in a non-level area, avoiding unstable operation or failure of the elevator caused by passengers prying the door. This helps to improve the overall operation quality and stability of the elevator.
[0054] The anti-pick door protection device provided in this embodiment, when the elevator is in the level area, the anti-pick door protection device contacts the striker plate 5 and is unlocked under the action of the striker plate 5, when the elevator is in the non-level area, the anti-pick door protection device is separated from the striker plate 5, and the anti-pick door protection device cannot be unlocked. In other words, the anti-pick door protection device provided in this embodiment can only be unlocked with the cooperation of the striker plate 5, and this embodiment increases the difficulty of unlocking to avoid the elevator door opening caused by user misoperation; and although the anti-pick door protection device provided in this embodiment makes the unlocking condition more stringent, when the elevator reaches the designated floor in normal operation, passengers can still enter and exit the elevator easily and quickly, which helps to improve the overall satisfaction and trust of users in the elevator.
[0055] The anti-pick-door protection device provided in this embodiment is not limited by the door system and the type of door blade, can adapt to various types of elevator door systems, has a wide range of applicability, and can be widely used in elevators of different brands and models. In addition, the anti-pick-door protection device provided in this embodiment is independent of other structures of the elevator, which means that even if other parts of the elevator fail or are abnormal, the anti-pick-door protection device provided in this embodiment can still remain effective, greatly improving the safety of the elevator and preventing safety accidents caused by door pick-doors.
[0056] like Figure 1-6 As shown, in one embodiment, the lock hook 33 is rotatably disposed on the movable seat 32 via a first connecting structure 36, wherein the first connecting structure 36 is disposed transversely so that the lock hook 33 can rotate in a longitudinal plane under the cooperation of the elastic member 34 and the striker plate 5.
[0057] This embodiment allows the lock hook 33 to rotate in the longitudinal plane with the cooperation of the elastic member 34 and the striker plate 5. That is to say, after the lock hook 33 is switched to the unlocked position and the elevator floor door is closed (that is, the striker plate 5 is not in contact with the lock hook 33), the lock hook 33 can naturally fall back under the action of gravity and switch from the unlocked position to the locked position to achieve natural closure, so as to ensure that the elevator floor door remains closed during the subsequent elevator operation, thereby improving the overall safety of the elevator system.
[0058] Furthermore, the structure provided in this embodiment that uses gravity to achieve natural locking is simple and reliable, reduces the probability of failure events caused by complex mechanical structures, improves the stability of the elevator system, and reduces maintenance and repair costs.
[0059] In one embodiment, the first connection structure 36 is disposed transversely relative to the horizontal plane, so that the locking hook 33 can rotate in the longitudinal plane under the cooperation of the elastic member 34 and the striker plate 5 .
[0060] In one embodiment, the first connection structure 36 is arranged parallel to the horizontal plane, so that the lock hook 33 rotates in a longitudinal plane perpendicular to the horizontal plane under the cooperation of the elastic member 34 and the striker plate 5 .
[0061] like Figure 2 As shown, in one embodiment, the first connecting structure 36 includes a rotating shaft 361, and the rotating shaft 361 is arranged on the surface of the movable seat 32 close to the locking hook 33, and the rotating shaft 361 passes through the locking hook 33, so that the locking hook 33 can be rotatably arranged on the movable seat 32.
[0062] like Figure 1-6 As shown, in one embodiment, one end of the lock hook 33 is bent to form a hook-shaped portion 332, and the other end of the lock hook 33 is provided with a first connecting structure 36;
[0063] An unlocking member 3311 is also provided on the lock hook 33. The unlocking member 3311 is located between the hook portion 332 and the first connecting structure 36. The distance between the unlocking member 3311 and the first connecting structure 36 is smaller than the distance between the unlocking member 3311 and the hook portion 332. The lock hook 33 contacts the striker plate 5 through the unlocking member 3311.
[0064] This embodiment allows the unlocking member 3311 to be away from the hook portion 332. When the striker plate 5 acts on the unlocking member 3311, a longer force arm can be generated, thereby making it easier to achieve a large rotation of the hook portion 332, so that the lock hook 33 can have a sufficiently long stroke during the unlocking process to complete the unlocking action, ensuring that the lock hook 33 is separated from the lock hook seat 4.
[0065] Furthermore, since the present embodiment realizes a large rotation of the hook portion 332, when the striker plate 5 acts on the unlocking member 3311, the lock hook 33 can quickly drive the hook portion 332 to rotate and separate from the lock hook seat 4, thereby realizing rapid unlocking and improving unlocking efficiency.
[0066] In one embodiment, the unlocking member 3311 includes a door ball.
[0067] like Figure 1-6 As shown, in one embodiment, the lock hook 33 is provided with a reset member 37, one end of the reset member 37 is arranged on the lock hook 33, and the other end of the reset member 37 is arranged on the connecting structure, and the reset member 37 is used to drive the lock hook 33 to rotate from the unlocking position to the locking position.
[0068] This embodiment realizes automatic locking by providing a reset member 37 to ensure that the elevator door remains in a closed state during the subsequent elevator operation, thereby improving the overall safety of the elevator system. In addition, the reset member 37 provided in this embodiment cooperates with the gravity locking structure to ensure that the lock hook 33 re-locks the lock hook seat 4, avoiding the situation where the gravity locking function fails when the lock hook 33 is disturbed by external forces (such as wind, vibration, etc.), ensuring that the lock hook 33 can quickly return to the locked state, further enhancing the safety of the elevator.
[0069] In one embodiment, the return member 37 includes a torsion spring, but is not limited thereto.
[0070] like Figure 1-6 As shown, in one embodiment, the lock hook 33 includes a lock hook body 331, an unlocking member 3311 is disposed on the lock hook body 33, one end of the lock hook body 331 is bent relative to the lock hook body 331 to form a hook-shaped portion 332, and the other end of the lock hook body 331 is bent relative to the lock hook body 331 to form a bent portion 333, and the first connecting structure 36 is located at the bent portion 333;
[0071] A limiting member 32111 is disposed on the movable seat 32 . The limiting member 32111 is located between the locking hook body 331 and the bending portion 333 to limit the rotation angle of the bending portion 333 .
[0072] In this embodiment, a limit piece 32111 is provided to limit the rotation range of the lock hook 33, thereby preventing the lock hook 33 from excessively rotating under the joint action of the elastic piece 34 and the striker plate 5, thereby reducing the risk that the lock hook 33 cannot be reset due to excessive rotation range, reducing the safety risks caused by the inability to reset the lock hook 33, and improving the stability and reliability of the anti-door pick-off protection device.
[0073] Furthermore, the end of the lock hook body 331 is bent relative to the lock hook body 331 to form a bent portion 333 to provide an accommodation space for the stopper 32111, so that the stopper 32111 can be cleverly accommodated between the lock hook body 331 and the bent portion 333, avoiding the stopper 32111 from bulging outward, making the overall structure compact and reducing the overall volume. In addition, the space utilization rate is improved and unnecessary space waste is avoided.
[0074] like Figure 1-6 As shown, in one embodiment, a mounting plate 321 is provided on the movable seat 32, and the mounting plate 321 includes a mounting portion 3211 and a blocking portion 3212, the mounting portion 3211 is provided on the movable seat 32, the limiting member 32111 is provided on the mounting portion 3211, and a first buffer member 32121 is provided on the blocking portion 3212, and the first buffer member 32121 is used to contact the lock hook seat 4.
[0075] In this embodiment, the blocking part 3212 is provided to prevent the lock hook seat 4 from colliding with the stopper 32111 under the drive of the door knife bottom plate 2, and the first buffer 32121 is provided to effectively reduce the impact force brought by the lock hook seat 4, reduce the damage caused by the lock hook seat 4 to the blocking part 3212, and prevent the blocking part 3212 from deformation and rupture, thereby enhancing the durability of the anti-pick door protection device and extending the service life of the anti-pick door protection device. In addition, the first buffer 32121 can also reduce the noise generated when the lock hook seat 4 collides with the blocking part 3212.
[0076] Specifically, the mounting portion 3211 is arranged parallel to the moving seat 32 , and the blocking portion 3212 is arranged perpendicular to the moving seat 32 .
[0077] In one embodiment, the first buffer member 32121 includes a silicone member.
[0078] like Figure 1-6 As shown, in one embodiment, the first end of the base 31 and the first end of the movable seat 32 are slidably connected via a second connection structure 38 ; the elastic member 34 is located between the second end of the base 31 and the second end of the movable seat 32 .
[0079] This embodiment separately arranges the second connecting structure 38 and the elastic member 34 at different positions to avoid mutual interference between the second connecting structure 38 and the elastic member 34 during operation, ensures that their respective functions can be performed normally, and helps to improve the stability and reliability of the anti-pick door protection device.
[0080] In addition, this embodiment can make full use of limited space resources by rationally planning the positions of the second connecting structure 38 and the elastic member 34, so that the sliding connecting structure and the elastic member 34 are arranged between the base 31 and the movable seat 32 in an optimal manner, thereby improving space utilization, making the overall structure compact, and reducing unnecessary space waste.
[0081] like Figure 1-6 As shown, in one embodiment, the second connecting structure 38 includes a guide rail 381 and a slider 382, one of the first end of the base 31 and the first end of the movable seat 32 is provided with the guide rail 381, and the other of the first end of the base 31 and the first end of the movable seat 32 is provided with the slider 382, and the guide rail 381 and the slider 382 are slidably connected.
[0082] The second connection structure 38 of this embodiment includes a guide rail 381 and a slider 382 , which helps to make the movement of the movable seat 32 relative to the base 31 more stable.
[0083] like Figure 1-6As shown, in one embodiment, the second end of the base 31 extends outwardly into a first arm 311 and a second arm 312, and the second end of the movable base 32 extends outwardly into a third arm 322 and a fourth arm 323, and the third arm 322 and the fourth arm 323 are both located between the first arm 311 and the second arm 312.
[0084] The elastic member 34 is provided with a guide rod 35, one end of the guide rod 35 is arranged on the first arm 311, and the other end of the guide rod 35 passes through the third arm 322 and the fourth arm 323 and is then arranged on the second arm 312. The elastic member 34 is wound around the guide rod 35, one end of the elastic member 34 abuts against the first arm 311, and the other end passes through the third arm 322 and then abuts against the fourth arm 323.
[0085] The elastic member 34 of this embodiment is provided with a guide rod 35, so that when the elastic member 34 drives the moving seat 32, the guide rod 35 can provide stable support for the elastic member 34, ensuring the stability of the movement of the moving seat 32. In addition, the guide rod 35 can provide movement guidance for the elastic member 34, ensuring the accuracy of the movement of the moving seat 32, which helps to improve the stability and reliability of the anti-pick door protection device.
[0086] like Figure 1-6 As shown, in one embodiment, a second buffer member 324 is disposed on the second arm 312 and / or the fourth arm 323 , and the second buffer member 324 is located between the second arm 312 and the fourth arm 323 .
[0087] The second buffer 324 of this embodiment effectively reduces the impact force of the mobile seat 32 on the base 31, reduces the damage caused by the mobile seat 32 to the base 31, and prevents the second arm 312 and the fourth arm 323 from being deformed or broken, thereby enhancing the durability of the anti-pick door protection device and extending the service life of the anti-pick door protection device. In addition, the second buffer 324 can also reduce the noise generated when the second arm 312 and the fourth arm 323 collide.
[0088] like Figure 1-10 As shown, this embodiment also provides an elevator, including the anti-door picking protection device described in any of the above embodiments.
[0089] The elevator provided in this embodiment includes an anti-door prying protection device, which can prevent passengers from prying the door to save themselves when the elevator car is not leveled, thereby avoiding the dangerous situation of falling into the shaft, and improving the safety of the elevator. At the same time, it can effectively prevent passengers (especially children) from prying open the elevator door, thereby reducing the risk of abnormal opening of the elevator door due to external interference and protecting passengers from accidental injuries. It can also ensure that the elevator door remains locked in a non-level area, avoiding unstable operation or failure of the elevator caused by passengers prying the door. This helps to improve the overall operation quality and stability of the elevator.
[0090] The elevator provided in this embodiment includes an anti-pick door protection device. When the elevator is in the level area, the anti-pick door protection device contacts the striker plate 5 and is unlocked under the action of the striker plate 5. When the elevator is in the non-level area, the anti-pick door protection device is separated from the striker plate 5 and cannot be unlocked. In other words, the anti-pick door protection device provided in this embodiment can only be unlocked with the cooperation of the striker plate 5. This embodiment increases the difficulty of unlocking and avoids the elevator door opening caused by user misoperation; and although the anti-pick door protection device provided in this embodiment makes the unlocking condition more stringent, when the elevator reaches the designated floor in normal operation, passengers can still enter and exit the elevator easily and quickly, which helps to improve the overall satisfaction and trust of users in the elevator.
