Description

A wind brace with a quick-release function for opening angle limit of an outer-hung window

technical field

The invention relates to the technical field of exterior window engineering, in particular to a wind brace for limiting the opening angle of an exterior-hung window with a quick-release function.

Background technique

At present, the hanging window has gradually become a popular window type in the construction industry. In the fire protection design, the hanging window needs to be opened at 70 degrees to meet the needs of fire and smoke exhaust. However, in daily use, it does not need to be opened at a large angle according to the ventilation requirements. Moreover, when opening at a large angle, people tend to lean outward, causing potential safety hazards; at present, the wind braces on the hanging windows generally can only limit the fixed opening angle and cannot be adjusted at will, and the wind braces are generally fixed on the hanging windows, which is inconvenient to disassemble and cannot be quickly Realizing daily and emergency two-way applications has certain risks and hidden dangers.

Contents of the invention

The present invention aims to solve the above-mentioned problems that the wind brace of the hanging window cannot be quickly disassembled, the opening angle is limited, and the two-way application of daily and emergency is inflexible, and provides a wind brace with a quick release function for the opening angle limit of the outer hanging window .

In order to achieve the above object, the present invention adopts the following technical solutions: a wind brace with a quick release function to limit the opening angle of the outer hanging window, including a wind brace chute, a slider, a fastening bolt, a quick release bolt, and a wind brace, The wind brace chute is installed on the main frame of the window, and the slider slides in the wind brace chute and is fixed by fastening bolts. One end of the wind brace is movably connected to the slider, and the other end is movably connected to the window sash, and the wind brace The rod and slider can be quickly disassembled through quick release bolts.

In particular, the wind brace chute is fixed on the window main frame by screws.

In particular, the fastening bolts are threaded on the slide block, and the slide block is fixed against the wind brace chute by the fastening bolts.

In particular, reinforcing ribs are provided on the wind struts.

In particular, the bottom of the nut of the quick release bolt is provided with a raised plate, and the quick release bolt is threadedly connected to the slide block.

In particular, one end of the wind strut is sleeved on the threaded rod of the quick release bolt and is held by a convex plate, and the end of the wind strut adjacent to the quick release bolt is provided with a quick release hole corresponding to the convex plate, and the wind strut rotates through the convex plate. Get out of the slider in the quick release hole.

The beneficial effects of the present invention are: the opening angle of the hanging window in daily use can be adjusted arbitrarily by setting the wind brace, the wind brace chute, the slider, the fastening bolt, and the quick release bolt; the number of components required by the wind brace Less, high standardization, with the demand for rapid and mass production; the wind brace is easy to disassemble, simple and convenient to use, and can quickly realize the switching between the daily and emergency states of the hanging window; The risk of the window, to ensure the safety of personnel, and does not damage the original structure of the hanging window, does not affect the overall quality of the window, which is conducive to the use of the hanging window in rooms with fire and smoke exhaust requirements.

The following will be described in detail in conjunction with the embodiments of the present invention with reference to the accompanying drawings.

Detailed ways

The present invention will be further described below in conjunction with embodiment:

As shown in Figures 1 and 2, a wind brace with a quick release function for opening angle limit of the outer hanging window, including a wind brace chute 3, a slider 6, a fastening bolt 7, a quick release bolt 9, and a wind brace 4. The wind brace chute 3 is installed on the window main frame 1, the wind brace chute 6 is fixed on the window main frame 1 by screws, the slider 6 is slid in the wind brace chute 3 and fixed by fastening bolts 7, The fastening bolt 7 is threadedly connected on the slider 6, and the slider 6 is fixed against the wind brace chute 3 by the fastening bolt 7. The wind brace 4 is provided with a reinforcing rib 5, and one end of the wind brace 4 is flexibly connected to the slider. On the block 6, the other end is movably connected to the window sash 2, and the wind strut 4 and the slider 6 are quickly disassembled through the quick release bolt 9.

The bottom of the nut of the quick release bolt 9 is provided with a convex plate 10, and the quick release bolt 9 is threadedly connected to the slider 6, and one end of the wind strut 4 is sleeved on the threaded rod of the quick release bolt 9 and is stuck by the convex plate 10 One end of the wind strut 4 adjacent to the quick release bolt 9 is provided with a quick release hole 8 corresponding to the convex plate 10, and the wind strut 4 is transferred to the quick release hole 8 through the convex plate 10 to disengage from the slider 6.

The components of the wind brace are made of stainless steel, and there will be no rust in outdoor use. The opening angle of the hanging window in daily use can be set by the processing length of the wind strut 4 .

The application scenario of the wind brace is suitable for the daily and emergency situations of the hanging window. In daily use, the hanging window does not need to be opened to a large angle. The wind brace acts as an angle limiter, and the limit angle depends on the length of the wind brace 4 and the position of slider 6.

When the sash 2 is opened and closed, the slide block 6 slides up and down in the track of the wind brace chute 3, and when there is no angle to be maintained, the fastening bolt 7 is tightened to fix the slide block 6 to realize the function of fixing the opening angle.

When using in an emergency state, rotate the quick-release bolt 9, turn the convex plate 10 into the quick-release hole 8, push the wind strut 4 sideways to separate it from the slider 6, and contact the opening angle limit of the window sash 10. At this time, the window sash 2 It can meet the functional requirements of the original hanging window with a large opening angle, so as to realize functions such as fire-fighting and smoke exhaust, emergency evacuation, etc.

After the emergency state is over, return the sash 2 to the length range of the wind brace 4, align the quick release hole 8 of the wind brace 4 with the quick release bolt 9, and rotate the quick release bolt 9 so that the convex plate 10 blocks the wind brace The rod 4 makes the wind strut 4 continue to be movably connected to the slide block 6, continues the angle limiting function of the sash 2, and returns to the daily small opening angle state.

The invention allows the opening angle of the hanging window to be adjusted at will during daily use, avoiding the risk of people falling due to the excessive opening angle of the outer hanging window in normal use; the number of components required for the wind brace is small, the standardization is high, and it has the advantages of rapid and mass production Requirements; wind braces are easy to disassemble, simple and convenient to use, and can quickly realize the switching between the daily and emergency states of the hanging window; it can reduce the risk of people leaning out to open the window in daily use, ensuring the safety of personnel, and not Destroying the original hanging window structure does not affect the overall quality of the window, which is conducive to the use of hanging windows in rooms with fire and smoke exhaust requirements.
