Hinge with adjustable sealing performance

Abstract

The invention relates to a hinge with adjustable sealing performance. An adjusting concave cavity is formed in an adjusting column, so that a first shaft part of an eccentric adjusting shaft can be inserted into the adjusting concave cavity, and the horizontal position of a window sash is adjusted by rotating a second shaft part which is eccentrically arranged; an adjusting nut is arranged, so that the axial position of the window sash is adjusted, then the window sash is adjusted according to needs, and the sealing performance of a product is improved; and a limiting clamping plate is arranged, so that the hinge is prevented from shaking in a closed state.

Description

technical field [0001] The invention relates to the field of building door and window hardware, in particular to a hinge with adjustable sealing. Background technique [0002] Existing hinges for doors and windows usually include a mounting plate, mutually hinged long support arms, short support arms, window mounting arms and other components. The mounting plate is provided with sliding parts, and its structure is relatively simple. Wherein the window frame and the window sash are fixed with hinges, and rely on the hinges to realize opening and closing. The difference in connection position of the window frame, sash and hinge will affect the degree of tightness after closing. In order to ensure the sealing of the window sash after closing, sealing strips are usually set on the window frame and sash. [0003] Modern energy-saving requirements are high, and windows require higher sealing performance, resulting in a larger design of the rubber strip and greater compression, re...

Problems solved by technology

On the other hand, customers hope to obtain a relaxed operating feel, which makes the gap between the hinge and the window closure need to be adjustable to meet the needs of different customers. Windows without gap adjustment functions cannot meet these requirements of different customers. Due to the extremely low outdoor temperature in some cold climate areas, the sealing performance between the window frame and the window sash is very high. If there is a small gap between the window sash and the window frame, the indoor temperature will drop a lot. Therefore, in order to reduce Difficult to install, the hinges of this kind of windows often have the adjustment function of adjusting the vertical and horizontal margins between the sash and the hinge, and this kind of structure can effectively avoid the inconsistency between the sash and the window frame caused by punching errors during installation. The problem that the window sash cannot be opened and closed normally due to being in a plane, but this type of hinge cannot solve the problem of sealing between the window sash and the window frame after it is installed on the window frame, that is, it cannot be adjusted when there is a large gap between the window sash and the window frame, resulting in The sealing performance is reduced, which cannot meet the needs of use well. At the same time, after the existing hinge is closed, the hinge still swings slightly, which affects the sealing of the window.
