Inner opening window door

Abstract

The invention relates to an inner opening window door which comprises an aluminum alloy window frame composed of aluminum alloy profiles with 45 degrees corner sections. The inner opening window dooris characterized in that inlay grooves are formed in the inner side surfaces of sealing plates, notch angles are formed in the top ends of the sealing plates with the 45 degrees corner sections, and plates are arranged on the notch angles; and the outer sides of the plates are arc faces, the inner sides of the plates are right angles, inlay plates are arranged on the two right angle sides of the plates, the inlay plates are embedded in the inlay grooves on the inner side surfaces of the sealing plates of adjacent aluminum alloy profiles correspondingly, and arc-shaped sealing strip inlay grooves are arranged on the place surfaces of the plates. Compared with the prior art, the inner opening window door has the advantages that the rigidity and strength of the aluminum alloy window frame areensured, the formation of sharp edges of the sealing plates are avoided, and safety is achieved.

Description

Technical field: [0001] The present invention relates to a window. Background technique: [0002] In the existing aluminum alloy windows that open inward, the window door is composed of a window frame and a plate such as glass arranged in the window frame, and the window frame is formed by joining four aluminum alloy frames with 45-degree angle cut surfaces at the head and tail. There are floating sealing plates around the window frame and inlaid grooves on the side of the edge of the sealing plate for inlaying sealing strips. In this way, when the window is closed, the window door can seal the window. The window with this structure is mainly used In the north below 0 degrees in winter. Because it is an inward-opening window, the window and door are located indoors when they are opened. In this way, when people walk indoors, they are easy to collide with the window and door. Since the sealing plate floating out is relatively thin, the angle after the 45-degree cut surface i...

Problems solved by technology

Because it is an inward-opening window, the window and door are located indoors when they are opened. In this way, when people walk indoors, they are easy to collide with the window and door. Since the sealing plate floating out is relatively thin, the angle after the 45-degree cut surface is joined is easy. Form a sharp edge, so that when a person touches the sharp edge, it is easy to cause injury to the human body

Existing doors for non-inward opening windows, as disclosed in patent CN200720053887.6, the main frame of the door is composed of metal profiles with mosaic grooves and plastic connectors, and the metal profiles are connected together through plastic connectors to form a Although the frame of the door uses plastic connectors and rounds the corners of the plastic connectors to solve the problem of hard corners formed by the 45-degree angled joints of the aluminum alloy frame, since it is connected by plastic connectors, the , the connector needs to be relatively thick to ensure its rigidity and strength. Since the door of the patent is a non-inward-opening window door, its structure is essentially different from that of an inward-opening window door. The sealing plate is relatively thin. If plastic connectors are used for connection, the plastic connectors must be relatively thin, and the frame of the inward opening window is relatively large. Such a structure must not meet the requirements for firm connection. Therefore, the above-mentioned The existing technology to solve the problem of hard corners formed by the 45-degree angled surface joint of the aluminum alloy frame cannot be transferred to the inward-opening window to solve the existing inward-opening window.
