Description

Technical Field

[0001] The utility model relates to the technical field of outward-opening windows, in particular to an outward-opening window. Background Art

[0002] An outward-opening window is a type of window. Its window sash is connected to the window frame through connectors such as hinges and can be opened outward at a certain angle, providing good ventilation. The outward-opening method allows air to enter the room more smoothly, increasing the indoor-outdoor air exchange and improving the indoor air quality. Even when the window is open, the inclined angle can effectively prevent rainwater from directly entering the room. Compared with traditional windows, the opening method of the outward-opening window reduces the risk of accidental falls by children.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Referring to Figure 2 , Figure 3 and Figure 4 , an embodiment provided by the present invention: an externally hung window, including a window frame 1 and a window sash 3. Hinge seats 4 are fixedly connected to the left and right ends at the rear sides of the window frame 1 and the window sash 3. Hinge shafts 5 are rotatably connected to the inner walls of the two hinge seats 4 on the left end and the two hinge seats 4 on the right end. Sliding grooves 6 are opened on the left and right sides of the inner wall of the window frame 1. A plurality of nut holes 7 are equidistantly opened on the adjacent sides of the inner walls of the two sliding grooves 6. Sliding bolts 8 are slidably connected to the inner walls of the two sliding grooves 6. Adjusting nuts 18 are threadedly connected to the far ends of the two sliding bolts 8 away from each other. Limiting strips one 9 are rotatably connected to the outer walls of the two sliding bolts 8. Rotating shafts 10 are arranged at the front ends of the two limiting strips one 9. Limiting strips two 11 are rotatably connected to the middle parts of the outer walls of the two rotating shafts 10. The adjacent sides of the two limiting strips two 11 are rotatably connected to the left and right bottom ends of the window sash 3. Buffer and vibration damping mechanisms 2 are arranged at the bottom of the front ends of the two limiting strips one 9;

[0040] Specifically, the left and right rear ends of the window frame 1 and the window sash 3 are connected by a hinge seat 4 and a hinge shaft 5, enabling the window sash 3 to rotate relative to the window frame 1. On the left and right sides of the inner wall of the window frame 1, there are sliding grooves 6, in which a plurality of nut holes 7 are equidistantly distributed. At the same time, a sliding bolt 8 can slide up and down in the sliding groove 6, and one end of it is threadedly connected to an adjusting nut 18. When it is necessary to adjust the maximum angle at which the window sash 3 is pushed outwards, rotate the sliding bolt 8 to loosen the adjusting nut 18 in the sliding groove 6, increasing the distance between the adjusting nut 18 and the top end of the sliding bolt 8 until the sliding bolt 8 is in a state where it can move freely up and down. Since there are a plurality of nut holes 7 with different heights in the sliding groove 6, the sliding bolt 8 can be moved to the nut hole 7 at the corresponding position. After finding the nut hole 7 at the appropriate position, rotate the sliding bolt 8 again to make the adjusting nut 18 engage with the nut hole 7 and tighten the rotation of the sliding bolt 8 again. During the process of the window sash 3 being pushed outwards, the first limiting strip 9 and the second limiting strip 11 function as limits. At the same time, since the first limiting strip 9 is rotationally connected to the sliding bolt 8, the second limiting strip 11 is connected to the first limiting strip 9 through a rotating shaft 10 and is rotationally connected to the window sash 3. When the window sash 3 is pushed outwards, as the window sash 3 rotates, the angles of the first limiting strip 9 and the second limiting strip 11 will change. During the adjustment process, by adjusting the positions of the sliding bolt 8 and the adjusting nut 18, the starting positions and the rotatable ranges of the first limiting strip 9 and the second limiting strip 11 are changed. Therefore, even when the window sash 3 is pushed outwards and the lengths of the first limiting strip 9 and the second limiting strip 11 when fully opened remain unchanged, the maximum angle that the window sash 3 can reach can be adjusted. Fix the adjusting nut 18 in the nut hole 7 at a higher position. When the window sash 3 is pushed outwards, due to the higher starting positions of the first limiting strip 9 and the second limiting strip 11 and the smaller limiting range, the window sash 3 can reach a larger opening angle. On the contrary, fix the adjusting nut 18 in the nut hole 7 at a lower position, and the maximum opening angle of the window sash 3 will be correspondingly reduced. By rotating the sliding bolt 8 and the adjusting nut 18, the maximum angle at which the window sash 3 is pushed outwards can be flexibly adjusted according to actual needs to meet different usage requirements.

[0041] Refer to Figure 4 and Figure 5 As shown in FIGS. 7 and 8, the buffer and shock absorption mechanism 2 includes a fixing plate 201. On the left and right sides of the top wall of the fixing plate 201, triangular grooves 202 are fixedly connected. Spring holes 203 are opened on the inner top walls of the two triangular grooves 202. Tension springs 204 are fixedly connected to the inner bottom walls of the two spring holes 203. The top ends of the plurality of tension springs 204 are fixedly connected to arc-shaped steel clips 205. Arc-shaped rubber pads 206 are fixedly connected to the top walls of the two arc-shaped steel clips 205. A cylindrical impact member 207 penetrates through the middle parts of the left and right sides of the second limiting strip 11, and the cylindrical impact member 207 is engaged with the two arc-shaped rubber pads 206;

[0042] Specifically, during the rapid closing of the window sash 3 or under the influence of external forces, the second limiting strip 11 will be driven to move inward. Since the cylindrical impact member 207 is fixed to the second limiting strip 11, it will move together with the second limiting strip 11. When the cylindrical impact member 207 approaches the two arc-shaped rubber pads 206, it will exert pressure on them, thereby pushing the arc-shaped steel clip 205 downward. The downward movement of the arc-shaped steel clip 205 will compress the tension spring 204 located in the spring hole 203. During the compression process, the tension spring 204 will absorb and store the impact energy from the cylindrical impact member 207. When the impact ends, the energy stored in the tension spring 204 will be gradually released, thus reducing the impact caused by the shaking of the window sash 3, protecting the window structure, and extending the service life of the window.

[0043] Referring to Figure 1 and Figure 2 , a plurality of T-shaped round holes 12 are equidistantly arranged around the inner wall of the window frame 1, and expansion bolts 13 are fixedly connected to the inner walls of the plurality of T-shaped round holes 12; the top end of the rear side of the window sash 3 is fixedly connected with a handle 14, and a rubber sleeve 15 is fixedly connected to the outer wall of the handle 14; a rubber strip 16 is fixedly connected to the outer wall of the window sash 3, and the rubber strip 16 is in mutual contact with the inner wall of the window frame 1;

[0044] Specifically, the expansion bolts 13 in the T-shaped round holes 12 can enhance the connection stability between the window frame 1 and the wall, ensuring that the window will not loosen due to external forces during use, improving the overall safety and stability of the window. The handle 14 facilitates the user to operate the opening and closing of the window sash 3, and the rubber sleeve 15 can increase the friction of the handle 14, and at the same time can also play a certain role in anti-slip and shock absorption. The rubber strip 16 is in contact with the inner wall of the window frame 1, which can enhance the sealing performance of the window, effectively block the intrusion of wind, rain, dust and noise, and improve the comfort of the interior.

[0045] Referring to Figure 2 , Figure 4 and Figure 5 , engaging grooves 17 are provided on the top walls of the two first limiting strips 9, and the inner walls of the two engaging grooves 17 are mutually engaged with the two cylindrical impact members 207; the four corners of the inner wall of the window frame 1 are all designed to be smooth, and the four corners of the outer wall of the window sash 3 are all smooth; the adjacent ends of the two sliding bolts 8 are both designed to be regular hexagons, and the middle parts of the adjacent ends of the two sliding bolts 8 are both designed to be hexagonal grooves;

[0046] Specifically, the engagement between the engaging groove 17 on the first limiting strip 9 and the cylindrical impact member 207 helps to maintain the stability of the first limiting strip 9 and the second limiting strip 11 after contraction, and reduces the occupied space of the two limiting strips, enabling the second limiting strip 11 to be hidden inside the first limiting strip 9. The rounded design of the corners of the window frame 1 and the window sash 3 reduces the risk of collision damage caused by sharp corners, increases the safety during use, and also makes the appearance of the window more beautiful and smooth. The regular hexagonal design at the top of the sliding bolt 8 facilitates the rotation operation of the sliding bolt 8 using tools, and the hexagonal groove design provides another operation method, increasing the convenience and flexibility of adjustment.

[0047] Working principle: The left and right ends of the rear sides of the window frame 1 and the window sash 3 are connected through the hinge seat 4 and the hinge shaft 5, enabling the window sash 3 to rotate relative to the window frame 1. Multiple nut holes 7 are equidistantly distributed in the sliding grooves 6 on the left and right sides of the inner wall of the window frame 1. At the same time, the sliding bolt 8 can slide up and down in the sliding grooves 6, and one end of it is threadedly connected to the adjusting nut 18. When it is necessary to adjust the maximum angle at which the window sash 3 is pushed outwards, rotate the sliding bolt 8 to loosen the adjusting nut 18 in the sliding groove 6 and increase the distance between the adjusting nut 18 and the top of the sliding bolt 8 until the sliding bolt 8 is in a state where it can move freely up and down. Since there are multiple nut holes 7 with different heights in the sliding groove 6, the sliding bolt 8 can be moved to the nut hole 7 at the corresponding position. After finding the nut hole 7 at the appropriate position, rotate the sliding bolt 8 again to engage the adjusting nut 18 with the nut hole 7 and tighten the rotation of the sliding bolt 8 again. During the process of the window sash 3 being pushed outwards, the first limiting strip 9 and the second limiting strip 11 act as limiting functions. At the same time, since the first limiting strip 9 is rotationally connected to the sliding bolt 8, the second limiting strip 11 is connected to the first limiting strip 9 through the rotating shaft 10 and is rotationally connected to the window sash 3. When the window sash 3 is pushed outwards, as the window sash 3 rotates, the angles of the first limiting strip 9 and the second limiting strip 11 will change. During the adjustment process, by adjusting the positions of the sliding bolt 8 and the adjusting nut 18, the starting positions and the rotatable ranges of the first limiting strip 9 and the second limiting strip 11 are changed. Therefore, even when the window sash 3 is pushed outwards and the lengths of the first limiting strip 9 and the second limiting strip 11 when fully opened remain unchanged, the maximum angle that the window sash 3 can reach can be adjusted. Fix the adjusting nut 18 in the nut hole 7 at a higher position. When the window sash 3 is pushed outwards, due to the higher starting positions of the first limiting strip 9 and the second limiting strip 11 and the smaller limiting range, the window sash 3 can reach a larger opening angle. On the contrary, fix the adjusting nut 18 in the nut hole 7 at a lower position, and the maximum opening angle of the window sash 3 will be correspondingly reduced.

[0048] Moreover, during the rapid closing of the window sash 3 or under the influence of external force, the second limiting strip 11 will be driven to move inwards. Since the cylindrical impact member 207 is fixed to the second limiting strip 11, it will move together with the second limiting strip 11. When the cylindrical impact member 207 approaches the two arc-shaped rubber pads 206, it will exert pressure on them, thereby pushing the arc-shaped steel clip 205 to move downwards. The downward movement of the arc-shaped steel clip 205 will compress the tension spring 204 located in the spring hole 203. During the compression process of the tension spring 204, it will absorb and store the impact energy from the cylindrical impact member 207. When the impact ends, the energy stored in the tension spring 204 will be gradually released, thereby reducing the impact caused by the shaking of the window sash 3.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
