Embodiment Construction
[0031] Combine below Figure 1~8 , the present invention will be described in detail according to four special states. This integrated car door lock asynchronous door knife device comprises a door knife base plate 4, a left knife arm 1, a right knife arm 15 and a lock hook 11 hinged on the door knife base plate through a bearing II 21. The hook bracket 13 is fastened, and when in the flat area, the floor gate ball 29 is located between the left knife arm 1 and the right knife arm 15. The lock hook 11 is provided with a main contact 12, and the lock hook bracket is provided with an auxiliary contact 14 matched with the main contact. The door knife bottom plate side is provided with some damping pads 16 and positioning pieces 26 for the right knife arm. The left knife arm 1 is hinged on the door knife base plate 4 by more than two left swing arms 3 (there are two in this embodiment, more than two left knife arms must be able to realize the corresponding functions, but compared...

An integrated car door lock asynchronous door knife device comprises a door knife bottom plate, a left knife arm, a right knife arm and a lock hook hinged to the door knife bottom plate. When the lockhook is at the horizontal position, the lock hook is buckled with a lock hook support. According to the technical scheme, the left knife arm is hinged to the door knife bottom plate through two or more left swing arms, one end of the right knife arm is hinged to the door knife bottom plate through a right swing arm, the other end of the right knife arm is hinged to the lock hook, the left knife arm is indirectly linked with the right knife arm through a lock hook, motor linkage, a car door lock and an asynchronous door knife are combined on an integrally-mounted door machine, and the above problems are thoroughly solved. The device is ingenious in structural design and has the beneficial effects of being simple in structure, easy to machine, mount and maintain, stable and reliable in running, capable of meeting the new national standard needs and the like. Under any condition, a car door in the unlocking area, and the outside of an office can be opened.
Description
technical field [0001] The invention relates to the field of elevators, in particular to a door blade unlocking device for elevators, in particular to an integrated car door lock asynchronous door blade device for elevators. Background technique [0002] my country's national standard stipulates that the horizontal distance between the inner surface of the elevator shaft and the edge of the nearest door of the car sill, car door frame or sliding door should not be greater than 0.15m. If the car is equipped with a mechanically locked door that can only be opened in the unlocked area of the landing door, and the car door is locked by an electrical safety device that meets certain requirements, the above distance is not limited. The newly revised national standard requires: when the car leaves the unlocking area, there should be a device to prevent the car door from being accidentally opened more than 50mm, and the blocking position can withstand a force of 1000N. This device...
