Abstract

The utility model relates to a door knife mechanism of a sundries elevator, which is an improvement of the structure of the door knife mechanism to realize the automatic opening and the automatic closing of a landing car door of a sundries elevator and solve the insufficiency that the landing car doors of past sundries elevators don not have automatic opening and automatic closing functions. The door knife mechanism is composed of a mounting base, a rotating shaft, a main rotating arm, a rotating arm, a wheel shaft, a bumping wheel, a guiding groove, an upper door knife, a lower door knife, a door knife shaft, springs and bearings. The utility model has the advantages that the automatic opening and the automatic closing of the landing car door of a sundries elevator are achieved, the smoothness of operation of the door knife mechanism is enhanced, the durability of the landing car door of a sundries elevator is enhanced and the utility model can be used for the sundries elevator.

Description

Dumb waiter door cutter mechanism

Technical field: the invention is the improvement to dumb waiter door cutter mechanism structure, is installed on the dumb waiter gate, realizes dumb waiter layer gate automatic switch.

Background technology: at present, the layer gate of domestic dumb waiter generally adopted the manually operated mode to realize not have the truly function of automatic opening and closing door by the switch door, therefore reduced the durability of layer gate greatly, increased the fugitiveness of elevator.

Summary of the invention: the purpose of the invention provides a kind of dumb waiter door cutter mechanism that can realize the layer gate automatic switch of dumb waiter; The purpose of the invention is achieved through the following technical solutions: dumb waiter door cutter mechanism: be by mounting seat, rotating shaft, main pivoted arm, pivoted arm, wheel shaft, hit wheel, guide groove, cutter, Xiamen cutter, door cutter shaft, spring, bearing constitute to the doorstep; Two rotating shafts and guide groove are installed on mounting seat, make strip hole on the guide groove, mounting spring in the rotating shaft is installed bearing in two rotating shafts, the main pivoted arm of fixed installation in a rotating shaft, wheel shaft is installed in main pivoted arm upper end, to hit wheel and be installed on the wheel shaft, two pivoted arms are inserted in the strip hole on the guide groove, its upper end is fixedly mounted on the bearing respectively, the middle part of two pivoted arms is fixed by the door cutter shaft cutter of will calling, and the lower end of two pivoted arms is fixed the Xiamen cutter by the door cutter shaft.

Description of operation: dumb waiter door cutter mechanism, integral installation is on gate, run into when hitting iron when hitting wheel, hit wheel along the orbital motion of hitting in the iron, at this moment hit wheel and at first move up again, when the time to left movement to left movement, main pivoted arm drives pivoted arm and promptly rotates counterclockwise to the right around two rotating shafts, two pivot point and four door cutter shaft points constitute two four-bar linkages, when upper and lower door cutter moves right be installed in layer on door lock mechanism contact, layer, gate are opened automatically.

The advantage of the invention: be used the layer gate automatic switch that to realize dumb waiter with the dumb waiter door lock mechanism; Owing to bearing has been installed in rotating shaft, and pivoted arm has been inserted in the strip hole of guide groove, improved the stationarity of running, therefore improved the durability of the layer gate of dumb waiter.

Description of drawings:

Fig. 1 is a dumb waiter door cutter mechanism structural representation;

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment: dumb waiter door cutter mechanism: by mounting seat 3, rotating shaft 12, main pivoted arm 5, pivoted arm 4, wheel shaft 8, hit wheel 6, guide groove 10, to the doorstep cutter 13, Xiamen cutter 14, door cutter shaft 1, spring 9, bearing 11 constitute; Two of rotating shafts, two of pivoted arms, pivoted arm is made hunchbacked shape, and makes the hole that cooperates with bearing in the upper end, makes the hole that cooperates with the door cutter shaft in middle part and lower end; On guide groove, make strip hole; Upper and lower door cutter is made the angle bar shape, makes the hole that cooperates with the door cutter shaft on one side at it; Mounting seat is made " " shape, is convenient to be installed on the gate, makes the hole that cooperates with rotating shaft thereon; Two rotating shafts of fixed installation on mounting seat, pocketed springs in one of them rotating shaft, in two rotating shafts, bearing is installed, main pivoted arm one end is fixedly mounted on the bearing, the two ends of spring are separately fixed on mounting seat and the main pivoted arm, spring can make main pivoted arm reset, wheel shaft is installed in main pivoted arm upper end, fastening with nut 7, to hit wheel is installed on the wheel shaft, hitting wheel adopts the rubber-like non-metallic material to make, play sound deadening, two pivoted arms are inserted in the strip hole on the guide groove, guide groove is fixedly mounted on the mounting seat, strip hole has guaranteed the stationarity that pivoted arm rotates, the upper end of two pivoted arms is fixed on the bearing, main pivoted arm and pivoted arm are rotated flexibly steadily, and the middle part of two pivoted arms is fixed by the door cutter shaft cutter of will calling, and uses nut locking, cutter can rotate around the door cutter shaft to the doorstep, the lower end of two pivoted arms is fixed the Xiamen cutter by the door cutter shaft, uses nut locking, and the Xiamen cutter can rotate around the door cutter shaft, use the nut locking place, have certain predetermincd tension between each part, prevent to become flexible, avoid fault to take place.
