Technical Field
[0001] This invention belongs to the field of windows, and specifically relates to a windproof sliding window. Background Technology
[0002] Currently, ordinary aluminum alloy sliding windows on the market have a large gap between the inner and outer windows and the upper and lower sliding surfaces. This causes the inner and outer windows to tilt slightly under the influence of gravity. The angle and direction of this tilt are random; it may tilt inwards or outwards. As a result, it is easy for outside wind to enter the room, making it ineffective for wind protection. At the same time, the drainage holes of existing sliding windows are located on both sides of the lower sliding surface of the window frame. When the window is closed, there is always one drainage hole on the outside and one on the inside, allowing wind to enter the room through both drainage holes. Summary of the Invention

[0008] As a further optimization of the present invention, the outer window protrusion and the inner window protrusion are interference-fitted with the outer window groove and the inner window groove, or the outer window protrusion and the inner window protrusion are made of elastic material.
[0009] As a further optimization of the present invention, the opening angle of the figure-eight structure or inverted figure-eight structure formed by the outer window and the inner window is no greater than 5°.
[0010] As a further optimization of the present invention, a window lock is also included, the window lock comprising an outer latch sleeve, an inner latch sleeve, a latch, a insert, and a first compression spring;
[0011] The outer latch sleeve is located on the side of the outer window hook; the inner latch sleeve is located on the side of the inner window hook, and the opening direction of the inner latch sleeve is opposite to the opening direction of the outer latch sleeve.

Detailed Implementation
[0039] The existing sliding window includes a window frame 1, an outer window 2, and an inner window 3.
[0040] The window frame 1 has an outer window sliding rail 1a1 and an inner window sliding rail on its lower side. The bottom of the outer window 2b is provided with an outer window sliding groove that is engaged with the outer window sliding rail 1a1. The bottom of the inner window 3b is provided with an inner window sliding groove that is engaged with the inner window sliding rail.
[0041] The upper slide 1b of the window frame 1 is provided with an outer window upper slide rail 1b1 and an inner window upper slide rail 1b2. The top of the upper part 2a of the outer window is provided with an outer window upper slide groove that is locked on the outer window upper slide rail 1b1. The top of the upper part 3a of the inner window is provided with an inner window upper slide groove that is locked on the inner window upper slide rail 1b2.
[0042] The external window sliding groove, external window upper sliding groove, internal window sliding groove, and internal window upper sliding groove are usually made of two parallel plates with a certain gap between them, hence they are also called plate 4.
[0043] The outer window and the inner window are staggered one after the other, respectively mounted on two parallel sliding rails 1a1 and 1b1 for the outer window and 1b2 for the inner window, and sliding on the two parallel sliding rails 1b1 and 1b2 for the outer window. By sliding left and right alternately, the outer window 2 and the inner window 3 can be in overlapping or spliced states to achieve the purpose of opening and closing the window.
[0044] Example 1
[0045] like Figure 1-4 As shown, this embodiment adds a brush 8 and a counterweight 9 to the existing sliding window. Specifically, a counterweight 9 and a brush 8 are provided on the plate 4 above the outer window 2a near the interior, and a counterweight 9 and a brush 8 are provided on the plate 4 above the inner window 3a near the exterior.
[0046] When the outer window 2 and the inner window 3 are installed on the window frame 1, the upper part 2a of the outer window will tilt inward due to the gravity of the counterweight 9, causing the outer window upper part 2a near the outside to rest against the upper slide rail 1b1 of the outer window. Similarly, the upper part 3a of the inner window will tilt outward, causing the inner window upper part 3a near the outside to rest against the upper slide rail 1b2 of the inner window.
[0047] Thus, the outer window 2 and the inner window 3 form an "eight"-shaped structure that converges at the top and separates at the bottom. In this structure, the brush 8 on the plate 4 near the interior of the outer window 2a is away from the upper sliding rail 1b1, and the brush 8 on the plate 4 near the exterior of the inner window 3a is also away from the upper sliding rail 1b2. Simultaneously, this embodiment also provides brush 8 on the plate 4 near the exterior of the outer window 2b and the plate 4 near the interior of the inner window 3b. Due to the "eight"-shaped structure of the outer window 2 and the inner window 3, the brush 8 on the plate 4 near the exterior of the outer window 2b is also away from the lower sliding rail 1a1, and the brush 8 on the plate 4 near the interior of the inner window 3b is also away from the lower sliding rail. Therefore, when the outer window 2 and the inner window 3 slide left and right on the window frame 1, the brush 8 minimizes contact with the sliding rail, reducing sliding resistance.
[0048] like Figure 5 , Figure 6As shown, in this embodiment, the outer window 2 is located on the left side, and the inner window is located on the right side. The side of the outer window latch 2c facing inwards has an outer window gasket 5 that is lower on the left and higher on the right, while the side of the inner window latch 3c facing outwards has an inner window gasket 6 that is higher on the left and lower on the right, opposite to the outer window gasket 5. When the window is closed, the outer window gasket 5 and the inner window gasket 6 overlap to form a sealing structure. In other embodiments, the outer window 2 can be located on the right side, and the inner window 3 on the left side, in which case the outer window gasket 5 is higher on the left and lower on the right, and the inner window gasket 6 is lower on the left and higher on the right.
[0049] Meanwhile, in this embodiment, the outer window gasket 5 and the inner window gasket 6 overlap to form a shape that is thicker at the top and thinner at the bottom, which is an inverted trapezoid in this embodiment. After the window is closed, the upper parts of the outer window gasket 5 and the inner window gasket 6 press against each other, causing the original "V"-shaped structure formed by the outer window 2 and the inner window 3 to become an inverted "V" shape. Under the inverted "V" shape, the brush 8 on the plate 4 near the interior of the upper 2a of the outer window will press against the upper slide rail 1b1 of the outer window, the brush 8 on the plate 4 near the exterior of the upper 3a of the inner window will press against the upper slide rail 1b2 of the inner window, the brush 8 on the plate 4 near the exterior of the lower 2b of the outer window will press against the lower slide rail 1a1 of the outer window, and the brush 8 on the plate 4 near the interior of the lower 3b of the inner window will press against the lower slide rail of the inner window, thereby achieving a sealing effect.
[0050] In this embodiment, the opening angle of the “eight” shaped structure and the inverted “eight” shaped structure formed by the outer window 2 and the inner window 3 is 1°. In other embodiments, it can also be 5° or other angles not greater than 5°.
[0051] Furthermore, brushes 8 are provided on opposite sides of both the outer window gasket 5 and the inner window gasket 6 to enhance the sealing effect of the outer window hook 2c and the inner window hook 3c after the window is closed.
[0052] In addition, when the outer window 2 and the inner window 3 form an inverted "V" shape, the counterweight 9 located at the top will further tend to increase the tilt angle of the upper part of the outer window 2a and the upper part of the inner window 3a, further strengthening the force of the brush 8 squeezing the slide rail and enhancing the sealing effect.
[0053] In this embodiment, when the window is closed, the pressure brush 8 enhances its sealing performance and improves its windproof effect; when the window is opened, the brush 8 does not affect the sliding effect of the outer window 2 and the inner window 3.
[0054] Preferably, such as Figure 7 , Figure 8As shown, in this embodiment, a vertical outer window strip groove 2e is provided on the side of the outer window light fixture 2d, and an outer window protrusion is provided on the left side of the window frame 1 at the position corresponding to the outer window strip groove 2e. After the outer window is closed, the outer window protrusion is inserted into the outer window strip groove 2e, which serves to seal the gap between the outer window light fixture 2d and the window frame 1. Furthermore, in this embodiment, the outer window protrusion is inclined from top to bottom towards the interior. The purpose of this structure is to allow the outer window 2 to better form an inverted "V" shape with the inner window 3 after closing, through the compression of the outer window protrusion and the outer window strip groove 2e.
[0055] Similarly, in this embodiment, a vertical inner window strip groove is provided on the side of the inner window light fixture 3d, and an inner window protrusion 1c is provided on the right side of the window frame 1 at the position corresponding to the inner window strip groove. After the outer window is closed, the inner window protrusion 1c is inserted into the inner window strip groove, which serves to seal the gap between the inner window light fixture 3d and the window frame 1. Furthermore, in this embodiment, the inner window protrusion 1c is inclined from top to bottom towards the outside. The purpose of this structure is to allow the inner window 3 to better form an inverted "V" shape with the outer window 2 after closing, through the compression of the inner window protrusion 1c and the inner window strip groove.
[0056] For ease of processing and installation, this embodiment actually provides external window slats and internal window slats 1c on both sides of the window frame 1, with two external window slats and two internal window slats 1c on each side, which are parallel to each other. The two external window slats and two internal window slats 1c respectively engage the two sides of the external window groove 2e and the internal window groove. In other embodiments, only one external window slat and one internal window slat 1c may be provided, but the external window slat and the internal window slat 1c need to be made thicker so that the two sides of the external window slat and the internal window slat 1c can abut against the two sides of the external window groove 2e and the internal window groove. In other words, it is best to use an interference fit between the outer window spur and the inner window spur 1c and the outer window groove 2e and the inner window groove. It should be noted that the degree of interference fit is only to ensure that the outer window spur and the inner window spur 1c can be locked with the outer window groove 2e and the inner window groove, but it does not affect the opening of the window. Therefore, the outer window spur and the inner window spur 1c can be made of plastic or elastic materials with a certain deformation capacity.
[0057] The tilt angle of the outer window slats and the inner window slats 1c, that is, the opening angle of the inverted "V" shape of the outer window slats and the inner window slats 1c, is also 0.1°, which is consistent with the opening angle of the inverted "V" shape formed by the outer window 2 and the inner window 3 when the window is closed.
[0058] This embodiment also provides a window lock 7, such as Figure 9 As shown, the window lock 7 specifically includes an outer latch sleeve 7a, an inner latch sleeve 7b, a latch 7d, a insert 7c, and a first compression spring 7e.
[0059] like Figure 11 As shown, the outer latch sleeve 7a is located on the side of the outer window hook 2c. The outer latch sleeve 7a is barrel-shaped and its opening faces inward.
[0060] As shown in Figure 12, the inner latch sleeve 7b is located on the side of the inner window hook 3c. In this embodiment, the inner latch sleeve 7b is sleeve-shaped; in other embodiments, the inner latch sleeve 7b can also be made into a barrel shape. In this embodiment, the opening direction of the inner latch sleeve 7b faces the outside and is opposite to the opening direction of the outer latch sleeve 7a.
[0061] The inner window hook 3c has a mounting groove on its side. The insert 7c and the first compression spring 7e are both located in the mounting groove. One end of the first compression spring 7e abuts against the bottom surface of the mounting groove, and the other end of the first compression spring 7e abuts against one end of the insert 7c. The other end of the insert 7c is an arc-shaped end 7c1.
[0062] like Figure 13 As shown, in this embodiment, the insert 7c is made into a semi-circular piece with a certain thickness. The other end of the first compression spring 7e abuts against the straight end 7c2. There are three first compression springs 7e, which abut against the upper, middle and lower parts of the straight end 7c2 respectively.
[0063] like Figure 14 As shown, in this embodiment, the pin 7d is cylindrical. One end of the pin 7d is inserted into the opening end of the outer pin sleeve 7a, and the other end of the pin 7d is inserted into the opening end of the inner pin sleeve 7b. The side wall of the other end of the pin 7d is provided with a slot 7d3 corresponding to the arc-shaped end 7c1.
[0064] The window lock 7 has two operating states: a locked state where the curved end 7c1 of the insert 7c is inserted into the slot 7d3, preventing the outer window 2 and the inner window 3 from sliding relative to each other; and an unlocked state where rotating the bolt 7d retracts the insert 7c into the mounting slot, causing the bolt 7d to disengage from the outer bolt sleeve 7a. Because the bolt 7d is cylindrical, rotating it easily compresses the curved end 7c1, preventing it from jamming.
[0065] The window lock 7 adopts this outward push structure, which, in addition to locking the window, also has the function of further pushing the outer window 2 and the inner window 3 from the "eight" shape to the outward "eight".
[0066] To facilitate the rotation of the pin 7d, this embodiment also provides a handle 7d2 on the side wall of the pin 7d, and a notch 7b2 is provided on the side wall of the open end of the inner pin sleeve 7b. In the locked state, the handle 7d2 is inserted into the notch 7b2, which makes it easy to disengage the pin 7d from the outer pin sleeve 7a to unlock it.
[0067] Furthermore, this embodiment also sets the end face of the opening of the inner pin sleeve 7b as an inclined surface 7b1. In the locked state, the handle 7d2 is located at the high position of the inclined surface 7b1, and in the unlocked state, the handle 7d2 is located at the low position of the inclined surface 7b1. During the transition between the locked and unlocked states, the handle 7d2 rotates against the inclined surface 7b1. Even further, a second compression spring is provided, located inside the opening of the outer pin sleeve 7a, with one end facing the opening of the outer pin sleeve 7a. During the unlocking process, the second compression spring can compress the pin 7d, allowing the handle 7d2 to rotate along the inclined surface 7b1 into the notch 7b2, improving the ease of unlocking.
[0068] like Figure 4 and Figure 15 As shown, a strip-shaped drainage channel 10 is formed by the downward sliding section 1a of the window frame 1 located between the outer window sliding track 1a1 and the inner window sliding track. In this embodiment, the drainage channel 10 is parallel to the outer window sliding track 1a1, and the two ends of the drainage channel 10 are respectively connected to the two sides of the window frame 1. In other embodiments, the two ends of the drainage channel 10 can also be set to be appropriately shorter. Specifically, the drainage channel 10 can be located in the middle of the downward sliding section 1a, and the two ends are not connected to the two sides of the window frame 1, or are only connected to one side of the window frame 1.
[0069] The side of the drainage channel 10 closest to the interior does not retract into the bottom surface below the interior window. In this embodiment, the side of the drainage channel 10 closest to the interior is flush with the outer side of the outer side of the inner window 3 facing the outside. This ensures that when the window is closed, the entire drainage channel 10 is located outdoors, preventing wind from entering the room through the drainage channel 10. This structure satisfies both drainage and windproof requirements.
[0070] To facilitate drainage, the bottom surface of the drainage channel 10 in this embodiment is inclined, with the end facing the outer window light fixture 2d being the high end and the end facing the inner window light fixture 3d being the low end, and a drainage hole is provided at the low end. This structure allows water in the drainage channel 10 to flow towards the outside and allows the drainage hole to be located outside the window.
[0071] In this embodiment, the inclination angle of the bottom surface of the drainage trough 10 is 0.65°. In other embodiments, the inclination angle of the bottom surface of the drainage trough 10 may also be 0.1° or other angles not greater than 5°.
[0072] In this embodiment, a drainage chamber 11 is provided below the drainage trough 10, and drainage outlets are provided at the drainage holes corresponding to the drainage chamber 11 and at the bottom of both ends of the side wall facing the outside of the drainage chamber 11. Water flowing downward from the drainage trough 10 enters the drainage chamber 11 through the drainage holes, and the water in the drainage chamber 11 flows to the outside through the drainage outlets. This embodiment has three drainage outlets to enhance the drainage effect. In other embodiments, drainage outlets may be provided only at the drainage holes corresponding to the drainage chamber 11, or at the bottom of one or both ends of the side wall facing the outside of the drainage chamber 11.
[0073] Example 2
[0074] This embodiment is basically the same as embodiment 1, except that in this embodiment, when the outer window 2 and the inner window 3 form an inverted "V" shape, the brush 8 moves away from the slide rail; when the outer window 2 and the inner window 3 form an "V" shape, the brush 8 presses against the slide rail to improve the sealing performance.
[0075] Specifically, in this embodiment, the card plate 4 above the outer window 2a near the outside is provided with a counterweight 9 and a brush 8, and the card plate 4 above the inner window 3a near the inside is provided with a counterweight 9 and a brush 8; the card plate 4 below the outer window 2b near the inside is provided with a brush 8, and the card plate 4 below the inner window 3b near the outside is provided with a brush 8; the outer window hook 2c facing the inside is provided with an outer window gasket 5, and the inner window hook 3c facing the outside is provided with an inner window gasket 6. The outer window gasket 5 and the inner window gasket 6 can be overlapped to form a structure that is thinner at the top and thicker at the bottom.
[0076] Furthermore, the sides of the outer window light fixture 2d and the inner window light fixture 3d are respectively provided with vertical outer window strip groove 2e and inner window strip groove; the two sides of the window frame 1 are respectively provided with outer window protrusion and inner window protrusion 1c corresponding to the outer window strip groove 2e and the inner window strip groove; the outer window protrusion slopes outward from top to bottom; the inner window protrusion slopes inward from top to bottom.
[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
