Ventilating door and window structures of built-in screen windows

Abstract

The invention discloses ventilating door and window structures of built-in screen windows, wherein each ventilating door and window structure mainly comprises an inner frame, a fixing baffle plate and two screen windows, wherein the inner sides of two vertical edges of the inner frame are provided with grooves facing to each other, and the grooves are divided into a first sliding groove and a second sliding groove; the inner side surfaces of two horizontal edges of the inner frame are provided with more than two outer frame strips so as to form an upper containing groove and a lower containing groove; the fixing baffle plate is provided with an upper groove and a lower groove, and the first sliding groove and the second sliding groove are internally provided with a first sliding baffle plate and a second sliding baffle plate; and the two screen windows are respectively arranged above and below the fixing baffle plate. According to the invention, the screen windows which are installed and fixed on the ventilating door and window can only be dismounted and taken down from the inner part mainly due to the arrangement of a blocking part on the inner frame which is close to the screen windows and faces to the external parts of the screen windows in a protruding mode, the screen windows can be prevented from being dismounted from outside by people effectively, and the ventilating door and window structure of the built-in screen window has the burglarproof benefit.

Description

technical field [0001] The present invention relates to a ventilation door and window structure, in particular to a ventilation door and window with a stopper, so that the screen window installed and fixed on the ventilation door and window can only be disassembled from the inside, so that the screen window can be effectively prevented from being broken by people. Ventilation door and window structure with built-in screens detached from the outside. Background technique [0002] According to the design of screen window components on the existing air convection flow door panel structure, as shown in Taiwan Patent No. 498924, M274437, M250028, etc., it not only has the benefit of increasing air convection flow, but also has quick installation and convenience to install the screen window Remove and clean other functions, but in fact, it does not consider that this kind of door and window structure cannot prevent unscrupulous people from removing the screen window from the outsi...

Problems solved by technology

[0004] However, although this anti-theft block has the above-mentioned advantages, in the assembly process, due to the setting of the anti-theft block, it is necessary to punch out some installation holes or holes on the screen window and its corresponding window frame track. groove, the anti-theft stopper can be assembled, and in this way, it is necessary to purchase stamping equipment and molds due to the stamping process, and an additional process time is required to install the anti-theft stopper. The manufacturing cost of a ventilation door remains high, so it cannot effectively enhance the competitiveness of the market
