Problems solved by technology
Usually, the device for retracting the safety touch panel to the inside of the door panel will be set independently, either using a combination of cam and connecting rod, or using other methods such as electric. These methods are relatively complicated and will increase the cost of elevator manufacturing and maintenance invisibly. cost

Embodiment Construction
[0026] like Figure 1 to Figure 4 As shown, the elevator door knife and movable light curtain linkage device of the present invention includes a set of elevator door knife device, a set of movable elevator light curtain assembly, and a set of door knife linkage mechanism.
[0027] According to the position of the movable arm of the door knife, it can be divided into two implementation modes. When the movable arm of the door knife is on the left side, the linkage mechanism is a linkage linkage structure, such as figure 1 , 2 As shown; when the movable arm of the door knife is on the right side, the linkage mechanism is a rigid rod structure, such as image 3 , 4 shown.
[0028] The above-mentioned door knife is driven by a certain device. When the elevator door is just opened, the movable arm 2 of the elevator door knife will clamp the door ball 3 of the landing door. When the elevator door is about to close, the movable arm 2 of the elevator door knife will Can release lan...

The invention discloses a linkage device for an elevator door cutter and a movable light curtain. The linkage device comprises a commonly used elevator door cutter device, a set of movable light curtain assemblies with safety touch plates and a set of door cutter link mechanisms for connecting the elevator door cutter and the movable light curtain. The elevator door cutter device is installed on an elevator door or an elevator door crane, and is a mechanical device which can guarantee the synchronous opening and closing of the landing door along with the elevator door through one drive device in the manner that when the mechanical device opens the door, a movable arm of the door cutter clamps a landing door ball, and when the door is closed, the movable arm of the door cutter releases the landing door ball. The simple link mechanisms are used for connecting the elevator door cutter device and the movable light curtain device, the movable light curtain can detect people or animals between door leaves mechanically, a device for independently driving the movable light curtain to move is replaced, the conception is novel, the design is ingenious, the structure is simple, the performance is reliable, the installation is convenient, and cost is low.
Description
technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator door knife and a movable light curtain linkage device. Background technique [0002] In some elevators currently in use, in order to ensure that people are not caught between the elevator doors by mistake, photoelectric sensing is often used to detect people or objects between the doors, and at the same time, safety touch points placed on the edge of the door panels are also used. The board uses a mechanical method to detect people or objects between the doors, which provides an extra insurance for the safety of the elevator. For this kind of safety touch panel, it is generally required that when the door is in the open state, the safety touch panel should protrude from the edge of the door panel to ensure that it can realize the detection function, and when the door is in the closed state, at least one side of the safety touch panel should be retracted ...
