Description

Technical Field

[0001] The invention relates to a sliding window, in particular to a balcony screen integrated thermally-broken sliding window. Background Art

[0002] Balconies are enclosed with aluminum alloy windows, commonly known as "sealed windows", which is a common practice in today's high-rise residential buildings. The above method can use the balcony space as a closed space, increasing the actual area that can be used for living. Since balconies are generally open spaces with long distances between columns, aluminum alloy window sashes need to withstand greater wind pressure, especially when encountering typhoons or tornadoes. The limit at the bottom of existing sliding window sashes is relatively fragile, and it is easy for the window sashes to be blown away from the window frame, causing personal or property losses. On the other hand, after the window is sealed, the inner side of the window sash is directly used as a living space, which places high requirements on the sealing and sound insulation performance of the window sealing structure, and the general sliding window structure cannot meet the requirements.

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0020] like Figure 1-Figure 4 As shown, a specific embodiment of the present invention provides a balcony screen integrated thermal break sliding window, comprising a sliding lower frame 1, a sliding upper frame 2, a window sash 3 and a window sash 4; the sliding lower frame 1 comprises a limiting lower frame 11 and a window sash lower frame 12, the window sash lower frame 12 is arranged on the inner side of the limiting lower frame 11, and the window sash 4 is arranged on the window sash lower frame 12; the limiting lower frame 11 forms a accommodating cavity 111, the top of the accommodating cavity 111 is provided with a sealing groove 112, and the bottom is provided with a guide rail 113, the bottom of the window sash 3 is provided with a supporting plate 5, the supporting plate 5 passes through the sealing groove 112 and extends into the accommodating cavity 111, the bottom of the supporting plate 5 is provided with a pulley 6, and the pulley 6 can slide on the guide rail 113; sealing strips (not shown in the figure) are provided on both sides of the sealing groove 112.

[0021] This solution integrates the structure of a sliding window and a screen window on the window frame, which has strong integrity, high strength, firmness and reliability. The bottom of the window sash 3 extends into the independent accommodating cavity 111. After installation, even if the window sash 3 is subjected to a lifting force, it cannot be separated from the window frame, which is highly safe. In addition, the problem of poor sealing of the bottom sliding part of the ordinary sliding window is solved. By setting a sealing groove 112 and setting sealing strips on both sides of the sealing groove 112, the sealing strips can be rubber strips or wool strips, which can perfectly achieve a sealed connection between the bottom of the window sash 3 and the window frame.

[0022] Preferably, the window sash 3 includes a window sash lower frame 31, and a card slot 311 is provided at the bottom of the window sash lower frame 31; a rectangular card block 51 is provided at the upper part of the support plate 5, and the rectangular card block 51 is inserted into the card slot 311; a triangular support frame 52 is provided at the lower part of the support plate 5, and the top of the support frame 52 is connected to the support plate 5, and the two side edges of the bottom extend downward to form a limit plate 521, and the pulley 6 is arranged between the limit plates 521.

[0023] It should be noted that the rectangular block 51 has strong torsion resistance and can reliably connect the support plate 5 to the lower frame 31 of the window sash; the triangular support frame 52 can evenly disperse the pressure of the window sash 3 to the pulley 6, and the support frame 52 has strong deformation resistance. When the window sash 3 is subjected to external force and attempts to be pulled out of the lower frame 31 of the window sash, the support frame 52 can reliably block under the sealing groove 112 to prevent the lower part of the window sash 3 from detaching from the lower frame 31 of the window sash.

[0024] In order to improve the sound insulation and heat insulation effect of the sliding window, the aluminum alloy frame of this embodiment adopts the broken bridge technology. The limit lower frame 11 includes an outer frame 13, an inner frame 14 and a bottom frame 15; the outer frame 13 and the inner frame 14 are connected by a heat insulation strip 16; the bottom frame 15 is arranged below the outer frame 13 and the inner frame 14, and extends from the inner side of the inner frame 14.

[0025] Among them, the bottom surface of the outer frame 13 on the side of which the heat insulating rubber strip 16 is provided is provided with a first hooking portion 131, and the bottom surface of the inner frame 14 on the side of which the heat insulating rubber strip 16 is provided is provided with a limiting tip 141 extending toward the first hooking portion 131; the upper surface of the bottom frame 15 is provided with a second hooking portion 151, and the second hooking portion 151 can be inserted between the first hooking portion 131 and the limiting tip 141, and abuts against the heat insulating rubber strip 16. Through the above design, the contact area between the bottom frame 15 and the inner frame 14 or the outer frame 13 can be reduced to a minimum, and it is arranged near the heat insulating rubber strip 16 with the strongest heat insulating ability, so as to reduce the heat transfer from the outer frame 13 to the inner frame 14 or the bottom frame 15. Compared with the ordinary sliding window structure without the bottom frame 15, its heat or sound is not easily transmitted directly to the lower wall through the outer frame 13, thereby improving the heat insulation and sound insulation effects.

[0026] Preferably, the bottom frame 15 is provided with a screen window slide rail 121, and the screen window lower frame 12 is provided on the screen window slide rail 121. The thermal insulation strips 16 are arranged in parallel in a group of two, and a group of thermal insulation strips 16 and the corresponding surface enclose a thermal insulation cavity 161.

[0027] In order to better utilize the bottom frame 15 to form a heat-insulating and sound-proofing barrier, a third hooking portion 142 is provided on the bottom surface of the inner frame 14, and a fourth hooking portion 152 is also provided on the upper surface of the bottom frame 15, and the fourth hooking portion 152 is hooked with the third hooking portion 142; the second hooking portion 151 and the third hooking portion 142 and the corresponding bottom surface of the inner frame 14 and the heat-insulating rubber strip 16 on the bottom frame 15 together form a central buffer cavity 7; the central buffer cavity 7 is adjacent to the heat-insulating cavity on the bottom frame 15 and the inner frame 14. Based on the above structure, when sound or heat attempts to propagate into the room through the window frame, it needs to pass through the central buffer cavity 7 and one or more heat-insulating cavities to further enhance the sound-insulating and heat-insulating effects of the sliding window.

[0028] In order to adapt to different balcony sizes, the window sash 3 also includes a window sash upper frame 32, and the upper part of the window sash upper frame 32 abuts against the fixed window frame 8. In addition, a decorative inclined plate 9 is also provided on the top of the window sash upper frame 32, and one end of the decorative inclined plate 9 abuts against the side of the fixed window frame 8. The decorative inclined plate 9 solves the current situation that the existing aluminum alloy window has only a rectangular frame appearance. The decorative inclined plate 9 provides a small amount of inclined surface, which cooperates with the rest of the frame surface, and the overall appearance is more high-end and fashionable.

[0029] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
