Embodiment 1

[0034] As attached figure 1 , 2 , 3, and 5, including the left and right landing doors 1 oppositely arranged, the upper door cover 2 arranged above the landing door 1, and the landing door sill 3 arranged below the landing door 1. The side door covers 4 on both sides of the landing door 1 are respectively arranged on the upper sealing structure above the landing door 1, and the lower sealing structure, the end stop 5 and several sealing strips 6 are respectively arranged under the landing door 1;

[0035] The upper door cover 2, the side door cover 4 and the floor door sill 3 are arranged on the wall;

[0036] The closed positions of the two landing doors 1 are provided with mutually offset and complementary stepped steps, and a sealing strip 6 is provided on the stepped steps;

[0037] The end stop 5 is vertically arranged at the outer end of the landing door 1, and a sealing strip 6 is vertically arranged on the side close to the side door cover 4. When the elevator door is closed,...

Embodiment 2

[0048] As attached Image 6 , 10 As shown, the difference between this embodiment and Embodiment 1 is that the separation control device in the lower sealing structure is different.

[0049] The separation control device includes a lower extension spring mounting seat 88 and a lower extension spring 89; the lower extension spring mounting seat 88 is fixed on the landing door 1 above the first rotating arm 821; the lower extension spring 89 The upper end is connected to the lower tension spring 89, and the lower end is connected to the upper surface of the front end of the first rotating arm 821.

[0050] As attached Image 6 , 10 As shown in 11, the lower seal of the door system can also be realized in the form of a tension spring, replaced with a lower tension spring 89 seat and a lower tension spring 89. When the door is opened, the lower swing arm 82 is pulled to the position of the lower limit block 85 due to the action of the lower compression spring 87, so that the sealing st...

Abstract

The invention discloses a fireproof and smokeproof door for an elevator. The fireproof and smokeproof door for the elevator comprises a left landing door, a right landing door, upper door sleeves arranged on the landing doors, landing sills arranged on the lower portions of the landing doors, side door sleeves, upper sealing structures arranged on the landing doors, lower sealing structures arranged on the lower portions of the landing doors, end stopping blocks and a plurality of sealing strips, wherein the left landing door and the right landing door are oppositely arranged; and the side door sleeves are arranged on the two sides of the left landing door and the two sides of the right landing door. The upper portion of the elevator door is sealed through the upper sealing structures; the lower portion of the elevator door is sealed through the lower sealing structures; due to cooperation of the end stopping blocks and the side door sleeves, the side portions of the elevator door are sealed; and the sealing strips are arranged between the two landing doors, and when the landing doors are closed, the portion between the landing doors is sealed. The fireproof and smokeproof door for the elevator is good in sealing effect, five portions of the elevator door can be totally sealed, the sealing devices are opened and closed along with movement of the landing doors, and design is simple, ingenious and practical.

Description

Technical field [0001] The invention relates to an elevator fire and smoke prevention door, in particular to a fully sealed elevator fire prevention and smoke release door. Background technique [0002] For some shopping malls, buildings, and apartment residences with dense populations, in the event of a fire, elevator escape becomes an important way of escape that affects life safety. The passenger elevators on the domestic market cannot be used under fire conditions. The main reason is that the elevator's landing door system cannot meet the technical requirements for fire and smoke prevention. [0003] At present, some marine fire doors, elevator fire doors that introduce fire prevention methods, and fire door headboards have been invented on the market. However, these inventions are only for the sealing method of fire doors, or for the control system. There is no invention that can easily open and close the landing door in the case of fire sealing, and there is no invention tha...
