Abstract

The utility model discloses a component of an elevator floor door system, and in particular discloses a novel elevator floor door device. The novel elevator floor door device comprises an upper bank frame, a floor door strap, a door hanging wheel and a locking device, wherein the locking device is used for controlling the opening/closing of the floor door, a strap pressing wheel component is connected to the door strap, the door hanging wheel is mounted on the door strap, a guide rail for the door hanging wheel to roll back and forth is arranged on the bottom of the upper bank frame, the cross section of the guide rail is in a transverse S shape, a convex ring is arranged on the outer surface of the pressing wheel of the strap pressing wheel component, the door strap is connected to the upper cambered surface of the guide rail through the door hanging wheel, and simultaneously, the convex ring on the outer surface of the pressing wheel is inserted into a notch with a downward opening in the guide rail. The technical problem that an existing floor door device is poor in application safety performance is solved; after the floor door of the elevator floor door system is matched with the novel elevator floor door device provided by the utility model, when the floor door is thrust by external force, the floor door only slightly shakes back and forth, and the working stability of the whole elevator floor door system is improved.

Description

Novel elevator layer door gear

Technical field

The utility model relates to a kind of elevator landing door system parts, particularly novel elevator layer door gear.

Background technology

Elevator landing door comprises upper sill frame, layer door hanging plate, door change gear and closing appliance, and layer door hanging plate is suspended on the guide rail of upper sill frame by the door change gear, and can prolong guide rail and move.

As shown in Figure 1; upper sill frame 1 in the existing layer door gear; its guide rail 2 parts are positioned at the waist of upper sill frame 1 integral body; this guide rail 2 parts belows usually have an extension 7 in order to door strap 3 on link plate pinch roller assembly 4 coordinate, to avoid door strap 3 guide rail 2 parts from upper sill frame 1 under the effect of external force, come off.But due to above-mentioned door strap 3 with upper sill frame 1 does not carry out cross spacing between the two or be unidirectional cross spacing, therefore after layer door installed with door strap 3, when external force is thrusted layer door, layer door there will be back and forth and rocks, occur that even layer door hanging plate deviates from the situation of guide rail, the usage safety performance of the whole elevator landing door of impact.

The utility model content

The purpose of this utility model is the novel elevator layer door gear that a kind of energy hoisting elevator layer door system working stability and safety are provided in order to solve above-mentioned the deficiencies in the prior art.

To achieve these goals, the novel elevator layer door gear that the utility model is designed, comprise upper sill frame, layer door hanging plate, door change gear and the closing appliance opened or closed for the key-course door, on described door strap, be connected with the link plate pinch roller assembly, the door change gear is installed on door strap, the bottom of described upper sill frame is formed with the guide rail rolled back and forth for the door change gear, the vertical section of this guide rail is " ∽ " shape, the pinch roller outside face of described link plate pinch roller assembly is provided with bulge loop, door strap is articulated on the upper cambered surface of guide rail by the door change gear, bulge loop on the pinch roller outside face inserts in guide rail upper shed recess down simultaneously.

When on the guide rail of door strap at upper sill frame, doing while moving back and forth, between bulge loop and guide rail, rub, affect door strap regular event in orbit, the utility model provides between the inwall of bulge loop described in novel elevator layer door gear and guide rail upper notch and is free-running fit, and each lateral wall of bulge loop is 1.3mm ~ 1.7mm with the gap width between the madial wall of corresponding recess, and the gap width between the bottom surface of its end face and recess is 3.2mm ~ 3.8mm.

The novel elevator layer door gear that the utility model obtains, the bottom of upper sill frame described in its structure is formed with the guide rail rolled back and forth for the door change gear, the vertical section of this guide rail is " ∽ " shape, the pinch roller outside face of described link plate pinch roller assembly is provided with bulge loop, door strap is articulated on the upper cambered surface of guide rail by the door change gear, bulge loop on the pinch roller outside face inserts in guide rail upper shed recess down simultaneously, the existence of above-mentioned matching relationship is arranged between the two due to door strap and upper sill frame, after when door strap, being installed on the guide rail of upper sill frame, guide rail will carry out the actv. cross spacing to door strap, therefore after the layer door in elevator landing door system installed with above-mentioned door strap, when external force is thrusted layer door, layer door only there will be the slight situation of rocking back and forth, promote the working stability of whole elevator landing door system.
