Embodiment

[0045]First, install the mounting bracket 1 to a desired position by screws, such as a door hanger. When the door knife needs to be used, the pusher 41 drives the push rod 42 to move, and then the push rod 42 passes through the The first moving part 35 pushes the moving rod 31 to move, and then one end of the connecting rod 32 rotates around the moving rod 31, and the other end of the connecting rod 32 moves the door knife push plate 23 through the hinged frame 22. At this time, the elastic member 33 is compressed; when the door knife needs to be reset, the compressed elastic member 33 resets the moving rod 31 through the second moving member 36, and then one end of the connecting rod 32 surrounds the The moving rod 31 reversely rotates, and the other end thereof passes through the hinge frame 22 to make the door knife push plate 21 move in the opposite direction until the door knife push plate 21 resets.

Abstract

The invention relates to an elevator door vane device which comprises a mounting frame, a door vane mechanism and a connecting mechanism. The mounting frame is provided with a pushing mechanism and alimiting plate. The end of a connecting rod is connected with the end, away from the mounting frame, of a hinging frame, so that the travel of a door vane push plate is long; due to resetting throughan elastic piece, restoring force of the elastic piece can be flexibly adjusted; a push rod abuts against a first moving piece, the position of the first moving piece on a moving rod can be conveniently adjusted, the moving distance of the moving rod can be adjusted, a motor is prevented from being burnt down, reliability is good, the service life is long, and the elevator door vane device is suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator door knife device. Background technique [0002] The elevator door knife is installed on the car door of the elevator and is used to drive the hall door to realize the synchronization of the hall door and car door. The elevator door knife is one of the indispensable parts of modern elevators. [0003] The Chinese patent with the application number 201720537723.4 discloses an elevator door knife, which includes a door knife mounting frame, a push plate, a three-eye connecting rod, a push rod mechanism, and a transmission rod. The connecting end at the middle part and the inner connecting end positioned at the inner side, the outer connecting end is rotatably connected to the push plate, and the inner connecting end is rotatably connected to the door knife mounting frame. The top end of the transmission rod is rotatably connected to the middle connection end, and the bottom en...
