[0004] The defect of the above-mentioned invention patent is that the opening and locking actions of the above-mentioned interlocking device and the door locking device are linked with each other, the interlocking device cannot be installed and used independently, and the existing elevator structure cannot be independently installed to realize the interlocking of the door panels. Moreover, the existing door-panel interlocking device is used in close cooperation with the landing door device, which is very complicated in structure, which is not conducive to re-installing the interlocking device on the existing elevator device, and is also not conducive to when one-sided door panel is stressed, it can be transformed into The condition that the double-sided door panels are evenly stressed

Embodiment Construction
[0023] The interlocking device for anti-falling door panels of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 1 , figure 2 In the anti-falling door interlocking device shown, the door interlocking device 8 includes a mounting bracket 3, a swing arm 4, a dead bolt 5, and a lock hook 6; The main focus of the lock device 8.
[0025] One end of the swing arm 4 is connected to the mounting bracket 3, the other end of the swing arm 4 is connected to the lock tongue 5, and the lock hook 6 is fixed on the closed end of the landing door panel 2, and the lock hook 6 is used to cooperate with the lock tongue 5 to intersect to realize the interlocking of the landing doors . The design of the swing arm 4 and the dead bolt 5 is to facilitate the overall folding and interlocking effect of the door panel interlocking device 8 during the closing and opening process of the landing door pan...

The invention relates to an anti-falling door plate interlocking device which comprises a landing door device, landing door plates and a door plate interlocking device body. The door plate interlocking device body comprises a mounting support, a swing arm, a spring bolt and lock hooks. The mounting support is connected with a shaft wall through expansion bolts. One end of the swing arm is connected with the mounting support, and the other end of the swing arm is connected with the spring bolt. The lock hooks are fixed to the closed ends of the landing door plates and used for cooperating with the spring bolt for achieving penetrating and inserting to achieve landing door interlocking. The anti-falling door plate interlocking device has the beneficial effects that door plate interlocking can be achieved after landing doors are closed, and it can be guaranteed that the door plates on the two sides can be stressed at the same time when the door plate on one side is impacted by external force.
Description
technical field [0001] The invention relates to the field of elevator structure layout, in particular to a door panel interlocking anti-falling device. Background technique [0002] Elevators are a must-have device for high-rise buildings in our current urban development, so now elevator safety has become our daily concern. As we all know, the elevator door is not a wall. When we wait for the elevator, leaning on the elevator door, hitting the elevator door and other similar behaviors are very dangerous. According to the national standard: when the elevator is still, the load-bearing capacity of the elevator door is about 15kg, and the force generated when the elevator door is closed is about 7.5kg. When the elevator is running, the bearing force of the inner door of the elevator is about 2.5kg. The elevator doors pinch the passengers, so the elevator has very little closing force. As a result, when the elevator is running, the elevator landing door will open as long as it...
