a lifting door

Abstract

The invention relates to a lifting door. The lifting door comprises a guide rail and a first door plate, wherein the guide rail comprises a longitudinal guide rail and a transverse guide rail; the longitudinal guide rail is vertically arranged; the transverse guide rail is horizontally arranged above the longitudinal guide rail; an arc guide rail is arranged between the transverse guide rail and the longitudinal guide rail for transition connection; first guide components are respectively arranged on the tops of the left side and the right side of the first door plate; second guide components are also respectively arranged on the left side and the right side of the first door plate; the second guide components are positioned below the first guide components; grooves which are communicated with one another are formed in the longitudinal guide rail, the transverse guide rail and the arc guide rail; the first guide components and the second guide components are arranged in the grooves; a hydraulic oil cylinder is also arranged in the groove in the lower section of the longitudinal guide rail; and a piston rod of the hydraulic oil cylinder is connected with the second guide component in a transmission way. The lifting door is good in wind-proof effect, anti-theft property and fire-proof property. After the lifting door is lifted, the rear door plate can be horizontally positioned at a lintel of a door, and the door which is turned can also be horizontally retracted through a transverse retracting device, so that the space is more concise.

Description

technical field [0001] The invention relates to a lifting door. Background technique [0002] At present, rolling doors are generally used at the entrances of garages, warehouses, shops, and shopping malls. The materials of rolling doors are generally iron sheet, aluminum sheet, and stainless steel sheet, that is, sheet materials are used as materials, and the door can be closed by lifting and lowering. However, the current rolling door still has deficiencies, such as poor safety performance, windproof performance, anti-theft performance and fireproof performance, and the rolling door occupies the space above the door beam after being folded up, which affects the appearance. Especially it is very unsafe to utilize this common rolling door in bank vaults, army firearms and ammunition depots. Contents of the invention [0003] In view of the technical problems in the background technology, the technical problem solved by the present invention is to provide a lifting door wi...
