Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 , figure 2 In the shown embodiment, an elevator synchronous door knife car door lock device includes a door knife assembly installed on the active door hanger, a secondary lock fixed on the passive door hanger and a door machine lower floor. The touch body mounting plate and the door knife assembly include a lock hook 1 that cooperates with the secondary lock and the touch body mounting plate. The lock hook and the auxiliary lock constitute the locking structure of the car door. The door knife assembly is the trigger control structure of the car door lock, and needs to cooperate with the gate ball 9 on the landing door.

[0029] The door knife assembly comprises a base plate 2, an active link 31, and a passive link 32, and the active link 31 and the passive link 32 are all hinged on the base plate 2 in the middle. A...

Abstract

The invention discloses a synchronous door cam and car door locking device of an elevator. The device comprises a door cam assembly which is mounted on an driving door hanging plate, a secondary lock fixed on a driven door hanging plate, and a triggering body mounting plate which is fixed on a lower bottom plate of a door machine; the door cam assembly comprises a lock hook which is in linkage fitting with the secondary lock and the triggering body mounting plate; the door cam assembly further comprises a bottom plate, a driving connecting rod and a driven connecting rod; the middles of the driving connecting rod and the driven connecting rod are hinged to the bottom plate; a fine moving blade and a movable blade are hinged between the driving connecting rod and the driven connecting rod to form a parallelogram structure; the fine moving blade is connected with the lock hook through a transmission mechanism; the driving connecting rod is connected with a door machine transmission mechanism; the door cam assembly is matched with a door ball on an elevator hall door to trigger the lock hook to act. With the adoption of the device, a car door and the hall door are synchronously opened and closed without adding extra triggering mechanism on the hall door; the mounting and repairing are convenient; the debugging is simple.

Description

technical field [0001] The invention relates to the technical field of elevator car door locks, in particular to an elevator synchronous door knife car door lock device. Background technique [0002] With the advancement of my country's modernization process, the use of elevators is becoming more and more extensive. At the same time, the safety performance of elevators is getting more and more attention. The door system with car door lock has better safety. At present, most of the car door locks on the market adopt a separate structure. This structure requires the installation of a mechanical structure on the landing door device to trigger the action of the car door lock, which takes up a lot of space and requires high installation accuracy. The car door lock must be adjusted on each floor. And the position of the trigger mechanism, the adjustment process is very loaded down with trivial details, and there are potential safety hazards. [0003] Such as Chinese Patent Public...
