Technical Field

The utility model relates to a door and window is spacing technical field, in particular to make the rotatory 170 connecting rod location wind brace of flat-open casement of installing the hinge.

Background

In modern buildings, windows are indispensable conditions for ventilation, lighting and decoration, and casement windows have good safety, sound insulation, sealing and heat preservation and simple operation, so the casement windows are widely applied to high-rise buildings, when ventilation is needed, the window is often supported and fixed by a positioning wind brace for ventilation, the positioning wind brace enables window sashes to be opened to a certain angle and fixed, the window sashes are limited to swing due to wind pressure, the opening angle of the traditional casement window is smaller than 90 degrees, in addition, the casement window is generally opened indoors due to the fact that the high-rise buildings prevent the casement window from falling off, the occupied indoor space is large, in addition, children or old people are often injured due to the edges and corners of the casement window, in order to increase the opening angle of the casement window, a plurality of improvements and creations are carried out on the wind brace for the casement window, but the improvements and creations often lead to complicated structures, cause the unstable scheduling problem after flat-open window opens, like patent number: "CN 205117005U full open type casement wind props stop device" opening angle is 180 degrees oversizes, makes the five metals handle of installation above its fan collide with the fixed glass on the window and cause the damage of glass and accessory very unsafe, and in addition when this kind of wind props and installs on flat-open window, because the orbit that the casement was opened is not an circular arc, so, can not install on the flat-open type casement wind props stop device to the whole loading of weight that leads to the flat-open window is on the wind props, can appear the wind and prop the motion deformation, or its fan and frame collision send great noise during the motion, long this past, lead to the flat-open window to damage.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that above-mentioned flat-open casement window fan wind brace that exists and take the hinge can not open and be greater than 90 or open 180 when, the hardware fitting of installation above the fan collides with window frame and glass and causes the damage of glass and accessory unsafe very much, for solving above-mentioned problem, the utility model provides a make the rotatory 170 connecting rod location wind brace of flat-open casement window fan who installs the hinge.

The purpose of the utility model is realized with the following mode: make the rotatory 170 connecting rod location wind braces of flat-open casement of installing the hinge, locate between window frame and the casement, including rectangular slide rail, rectangular slide rail fix the window frame on, seted up the sliding tray on the rectangular slide rail, be equipped with one on the rectangular slide rail with sliding tray complex slider, one side of rectangular slide rail is equipped with chevron shape link assembly, chevron shape link assembly includes first connecting rod, second connecting rod and third connecting rod, first connecting rod one end articulates on the slider, the articulated second connecting rod middle part of first connecting rod other end, second connecting rod one end articulates at rectangular slide rail right-hand member, the second connecting rod other end articulates the one end at the third connecting rod, the third connecting rod other end articulates there is the fan connecting plate, the fan connecting plate articulates on the casement.

A plurality of convex blocks are fixed on the sliding groove at intervals.

And the sliding block is provided with a positioning bolt.

The fan connecting plate is an arch bridge-shaped rectangular plate, the fan connecting plate is fixed on the window sash through screws, and the third connecting rod is hinged to the fan connecting plate.

A lug is fixed at the right end of the sliding groove.

The fixing holes are formed in the two ends of the long-strip sliding rail, and the screws fix the long-strip sliding rail on the window frame through the fixing holes.

Compared with the prior art, the utility model discloses a slider, chevron shape link assembly and third connecting rod's cooperation makes the casement opening angle about 170, effectively solved the casement and opened the undersize, it is big to occupy the indoor space, the window shines into the injury easily to children by the edges and corners, the casement angle is opened oversize, influence life, and chevron shape link assembly and third connecting rod are when opening, form triangle-shaped, make location wind brace more stable, effectually prevent that the casement from rocking after opening, be equipped with protruding piece in the sliding tray in addition, prevent that the slider from sliding through the fix with screw back, thereby lead to the casement to rock, the stability of location wind brace has further been increased.
