Assembly connecting structure of inward side-hung window

Abstract

The invention belongs to the field of inward side-hung windows, and particularly discloses an assembly connecting structure of an inward side-hung window. According to the assembly connecting structure of the inward side-hung window, window frame connectors and movable sash frame connectors of different structures are adopted, and under the conditions of meeting respective requirements for connecting strength, the production cost of the side-hung window is lowered. The assembly connecting structure of the inward side-hung window comprises a window frame and a movable sash frame, the window frame connectors are arranged at the four corners of the window frame, and the movable sash frame connectors are arranged at the four corners of the movable sash frame. The window frame connectors comprise left supports and right supports, first cavities and second cavities are formed in the left supports and the right supports, a hollow column is arranged in each first cavity, three hollow columns are arranged in each second cavity, and the axial direction of the hollow columns is perpendicular to the length direction of the left supports and the length direction of the right supports. The movable sash frame connectors comprise connector bodies, a plurality of protrusions are arranged on an outer frame of each connector body at intervals, a plurality of grooves are formed in an inner frame of each connector body at intervals, and supporting columns are arranged between the two sides of the bottom edges of the grooves and the inner frames.

Description

technical field [0001] The invention belongs to the field of inner casement windows, in particular to an assembly and connection structure of inner casement windows. Background technique [0002] At present, there are mainly two types of exterior windows used in buildings: casement windows and sliding windows. Among them, sliding windows were popular in the market due to their reliable use and simple processing in the initial stage of popularization and use. However, after years of engineering practice tests, many of their shortcomings gradually emerged. One of the components, its main disadvantage is that the sealing performance is poor, and the air tightness and water tightness indicators are not good, which is unfavorable for heat preservation, heat insulation, energy saving and environmental comfort. Therefore, most of the current high-rise buildings use casement windows. [0003] During the assembly process of the existing casement windows, the group corners of the wi...

Problems solved by technology

[0003] During the assembly process of the existing casement windows, the group corners of the window frame and the fan frame are connected by the corner codes with the same structure, but in the actual use process, the force received by the window frame and the fan frame is not the same, so the two The required connection strength is also different. If the corner brackets with the same structure are used, if the connection strength of the corner brackets is too large, the production cost will increase. If the connection strength is low, the window frame or fan frame will be loosened, which will affect the entire system. The use of door and window structures
