Embodiment Construction

[0021] Please see first figure 1 , a door leaf 1, rectangular, and preferably rectangular, it can be fixed to the door stile 301 by the installation and fixing holes 11 that are basically evenly distributed on it, although 4 installation and fixing holes are shown in the figure 11, but this is not the only one. For example, installation and fixing holes 11 can be opened on the upper, middle and lower sides of the two sides, thereby increasing the number of installation and fixing holes 11 to six. A material is a bent plate 4 made of stainless steel, the front end of which is welded vertically to one side of the door leaf 1 facing the door frame leaf 2, and is slightly offset. The height of the bent plate 4 is suitable for passing through the rectangular hole 21. A limit step 42 is formed on the upper end of the bent plate 4. The function of the limit step 42 is to control the movement of the body of the bent plate 4 through the rectangular hole 21. degree. The end of the ben...

Abstract

A hinge with improved structure is composed of a hinge plate for door sash, a hinge plate for door frame, and a mandrel. Said hinge plate for door sash has an extended and curved plate whose end is curled for passing the mandrel through it. Said hinge plate for door frame has a central rectangular hole for recepting said curved plate, and upper and lower connecting plates with mandrel hole on them. The lower end of mandrel has a fastening part. When the door is closed, the hinge is hidden. Its other advantages are low friction and noise, and flexible rotation.

Description

technical field [0001] The invention discloses a hinge with improved structure, in particular to a hinge used for a combined door of a metal-pressed sandwich panel and an aluminum alloy profile. Background technique [0002] Hinges in the prior art can be roughly divided into three categories: one is exposed hinges; the other is exposed hinges; the third is concealed hinges, which are also called invisible hinges. [0003] Exposed hinges and exposed hinges are widely used in the connection between door leaf and door frame, window leaf and window frame of buildings. The disadvantages of these two types of hinges are: the former, no matter whether the door leaf is in the open or closed state, the hinge shaft or the hinge mandrel used to pivot the two hinge plates is always exposed outside, which is easy to be cut in by external attacks. The goal is especially for those who have the intention of stealing into the room; there is a gap between the door leaf and the door frame at...
