Description

Technical Field

[0001] The utility model relates to the technical field of window guard rails, in particular to an openable window guard rail. Background Art

[0002] Railings, known in ancient China as langgan (Langgan), or "hoolan" (Gou Lan), are safety features found on bridges and buildings. They serve as dividers and guides, ensuring clear boundaries between divided areas. Well-designed railings are highly decorative. Formally, they can be categorized into two types: intersegmental and continuous. The former consists of columns, handrails, and crossbars, with the handrails supported on the columns; the latter has a continuous handrail, consisting of a handrail, railing posts, and a base. To improve the safety of windows in high-rise buildings, window guards are often installed on the inside of the windows. To enhance the sealing effect of the windows, the windows are often designed to open inwards.

[0003] During the use of bedroom windows, in order to increase the ventilation area of the windows, some windows are set as two sets of upper and lower movable windows. However, at this time, the lower half of the window cannot be opened due to the obstruction of the window guard railings, which makes the movable windows in the lower half unable to be opened, affecting the indoor ventilation effect. Some users choose to remove the window guard railings. Although the lower half of the window can be opened at this time, the safety of window use is reduced.

[0004] Therefore, it is necessary to invent a kind of openable window guard railing to solve the above problems. Utility Model Content

The lower end of the fixed guardrail 1 is fixedly connected to the upper surface of the bay window, and the movable guardrails 2 on both sides are respectively rotatably connected to the walls on both sides. A locking module is provided between the fixed guardrail 1 and the movable guardrail 2, and the locking module includes a first connecting block 11, a plug-in slot 12, a second connecting block 21, a positioning slot 22, a positioning block 23, a support spring 24, and an adjustment block 28. The first connecting block 11 is respectively fixedly connected to the upper and lower sides of the left and right ends of the fixed guardrail 1, and the second connecting block 21 is respectively fixedly connected to the upper and lower sides of the movable guardrail 2 close to the fixed guardrail 1. The plug-in slot 12 is opened on the side of the first connecting block 11.

[0034] Among them, the fixed guardrail 1 and the movable guardrail 2 are installed on the upper side of the bay window, the fixed guardrail 1 is installed on the inside of the fixed window sash, and the movable guardrail 2 is installed on the inside of the movable window, and the window is set to two parts, the upper part can be opened for ventilation under normal conditions, and the locking module is in a locked state. At this time, the fixed guardrail 1 and the movable guardrail 2 are a whole, protecting the lower part of the window. When the window needs to be opened in a large area for ventilation, the locking module is opened, and the movable guardrail 2 is rotated outward. At this time, the lower part of the window is opened, thereby increasing the ventilation area of the window.

[0035] See Figure 1 、 Figure 2 and Figure 6 The lower end of the fixed guardrail 1 is fixedly connected to the first connecting plate 13, and the first connecting plate 13 is fixedly connected to the surface of the bay window through expansion bolts. The end of the movable guardrail 2 close to the wall is fixedly connected to the first rotating block 29, and the surface of the first rotating block 29 is rotatably connected to the second rotating block 31. The side of the second rotating block 31 is fixedly connected to the second connecting plate 3, and the second connecting plate 3 is fixedly connected to the wall through expansion bolts.

[0036] Specifically, through holes are provided on the surfaces of the first connecting plate 13 and the second connecting plate 3. The expansion screws are passed through the through holes on the surface of the first connecting plate 13 to connect with the bay window, and then the first connecting plate 13 and the fixed guardrail 1 are locked and fixed. The expansion screws are passed through the through holes on the surface of the second connecting plate 3 to connect with the wall, and then the second connecting plate 3 is locked and fixed to the wall. The position of the movable guardrail 2 is positioned, and the movable guardrail 2 rotates around the second connecting plate 3 through the cooperation of the first rotating block 29 and the second rotating block 31.

[0037] See Figure 4 and Figure 5 The positioning groove 22 is opened inside the second connecting block 21, and the positioning block 23 is slidably connected to the positioning groove 22. The positioning block 23 is located at one end outside the positioning groove 22 and is arc-shaped. The support spring 24 is located inside the positioning groove 22, and the two ends of the support spring 24 respectively abut against the side wall of the positioning groove 22 and the end of the positioning block 23. The upper and lower inner walls of the positioning groove 22 are provided with limiting grooves 25. The upper and lower surfaces of the positioning block 23 at one end inside the positioning groove 22 are fixedly connected to the limiting block 26. The limiting block 26 is slidably connected to the limiting groove 25. The front side surface of the second connecting block 21 is provided with an adjusting groove 27. The adjusting groove 27 is connected to the positioning groove 22. The adjusting block 28 is slidably connected to the adjusting groove 27, and the inner end of the adjusting block 28 is fixedly connected to the positioning block 23.

[0038] In addition, when locking the fixed guardrail 1 and the movable guardrail 2, the movable guardrail 2 is directly rotated toward the side of the fixed guardrail 1, and the positioning block 23 is located at one end outside the positioning groove 22 and is set to an arc shape, so that the positioning block 23 can slide directly into the inside of the plug-in groove 12. At this time, the locking module is locked and fixed, and then the fixed guardrail 1 and the movable guardrail 2 are locked and fixed.

[0039] At the same time, when the movable guardrail 2 is opened to the outside, the adjusting blocks 28 in the upper and lower locking modules are slid sideways inside the adjusting slots 27, thereby driving the positioning blocks 23 to slide inside the positioning slots 22. At this time, the end of the positioning block 23 located outside the positioning slot 22 is separated from the inside of the plug-in slot 12. At this time, the movable guardrail 2 can be rotated to the outside. After loosening the adjusting block 28, the supporting spring 24 pushes the positioning block 23 outward, and the positioning block 23 and the adjusting block 28 are reset.

[0040] The working principle of the utility model is as follows: by unlocking the locking module and rotating the movable guardrail 2 outward, the lower half of the window is opened, effectively improving the ventilation effect of the window. At the same time, when large-area ventilation is not required, the locking module is locked, so that the fixed guardrail 1 and the movable guardrail 2 are integrated as a whole to improve the safety of use. While ensuring safety, a large area of window opening can be achieved, effectively improving the indoor ventilation effect and improving the convenience of use.
