DETAILED DESCRIPTION
[0033] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0034] like Figures 1 to 3 A sliding door and window anti-slip sealing system includes two or more door and window sashes mounted between an upper frame 6 and a lower frame 5. The door and window sashes include a sash plate, an upper stile 7 fixed to the top of the sash plate, a lower stile 8 fixed to the bottom of the sash plate, and a pulley 9 mounted within the lower stile 8. The door and window sashes are rollingly mounted on vertical rails 5-2 within the mounting grooves of the lower frame 5 via pulley 9.
[0035] like Figure 1 The top of the upper stile 7 of the door and window fan is flush with the top of the hook, and the bottom end of the lower stile 8 of the door and window fan is flush with the bottom end of the hook.
[0036] like Figures 6 to 8 Two adjacent door and window sashes are joined by an indoor hook 3 and an outdoor hook 4. The indoor hook 3 is equipped with a reinforcing protrusion that protrudes indoors and runs the entire length of the door and window. The indoor hook 3 and the outdoor hook 4 overlap each other through the overlapping portion, improving sealing performance while also enhancing the stability of the door and window sash, thereby increasing the safety of the sliding door and window.
[0037] Sealing strips are secured within the first sealing slot 3-1 on the indoor hook 3 and the second sealing slot 4-1 on the outdoor hook 4. The sealing strips within the first sealing slot 3-1 and the second sealing slot 4-1 overlap and seal with the opposing overlapping surfaces. The first wedge-shaped claw 3-3 on the indoor hook 3 and the second wedge-shaped claw 4-3 on the outdoor hook 4 interlock to enhance sealing. The first limiting baffle 3-2 and the inner side surface 3-4 of the first slot form a first channel with the overlapping surface of the indoor hook 3. The second limiting baffle 4-2 and the inner side surface 4-4 of the second slot form a second channel with the overlapping surface of the outdoor hook 4.
[0038] The top and bottom ends of the first and second channels are respectively provided with anti-slip seals 2. The anti-slip seals 2 include plug-in protrusions, and the anti-slip seals 2 are plugged into the channel via the plug-in protrusions. The plug-in protrusions include a second blocking surface 2-5 for blocking the channel, and the plug-in protrusions are plugged into the channel via a first limiting side surface 2-6 and a second limiting side surface 2-7 vertically connected to the second blocking surface 2-5. The anti-slip seals 2 also include a heightening block 2-1 for sealing the ends of the hook-and-edge overlap portion and preventing the door and window sashes from falling off. The heightening block 2-1 also includes a third blocking surface 2-8 for blocking the gap between the wedge-shaped claw and the hook-and-edge overlap surface on the side facing the overlap portion, and a first blocking surface 2-4 for blocking the gap at the bottom end of the sealing slot. Countersunk holes 2-3 for accommodating screw heads are provided on the two side surfaces of the heightening block 2-1 parallel to the overlap surface, and the bottom surfaces of the two countersunk holes 2-3 are connected by a through hole 2-2. With the plug-in cooperation between the plug-in protrusion of the anti-slip seal 2 and the channel, the anti-slip seal 2 can be fixed to the corresponding overlapping surface by only one screw without swinging, which simplifies the operation process and improves the installation efficiency.
[0039] A third sealing slot 2-9 and a fourth sealing slot 2-10 are provided on one side of the heightened block 2-1 near the lap joint and on the opposite side, respectively. A U-shaped sealing strip is fixed to the anti-slip seal 2 connected to the top of the hook-and-edge lap joint. The ends of the U-shaped sealing strip extend through the third and fourth sealing slots 2-9 and 2-10, respectively, with their openings facing the corresponding lap joints. This seals the gap at the top of the hook-and-edge lap joint.
[0040] like Figure 3, let h1 be the distance between the top of the hook and the bottom of the upper sliding sealing rib 6-1 in the installation groove of the upper frame 6; h2 be the distance between the top of the hook and the bottom of the upper sliding sealing rib 6-1; h3 be the distance between the top of the upper stile 7 and the top surface of the installation groove of the upper frame 6; h4 be the overlapping height between the lower stile 8 of the door and window sash and the side stop 5-1 of the lower frame 5; and h5 be the height of the heightened block 2-1 of the anti-slip seal 2. To ensure that the upper sliding sealing rib 6-1 and the side stop 5-1 of the frame do not hinder the insertion of the door and window sash, the following conditions must be met: h1+h3≥h1+h2>h4; to ensure that the anti-slip seal 2 effectively prevents it from falling off, the following conditions must also be met: h2-h5≥5mm and h5 / h2≥80%. As a preferred example of the present invention, h1=10cm, h2=h3=13cm, h4=8cm, h5=11cm. When this parameter is met, the door and window sashes can be inserted smoothly, and the anti-fall-off function of the anti-fall-off seal 2 can also be effectively exerted.
[0041] like Figure 1 and Figure 2 The anti-slip sealing system further comprises an X-shaped sealing member 1 provided on the downwardly sliding sealing rib 5-3, the top of the X-shaped sealing member 1 contacts the bottom of the anti-slip sealing member 2 at the lower end of the channel. Figure 5 The "X"-shaped seal 1 is made of a flexible material with high elasticity and aging resistance. Its bottom is provided with an inner cavity 1-3 that cooperates with the downward sealing rib 5-3. The top surface of the "X"-shaped seal 1 is evenly spaced with multiple parallel strip-shaped water retaining ribs 1-2, which are used to block the hook and the bottom end of the anti-slip seal 2 to improve sealing. Anti-slip claws 1-1 are provided on both sides of the "X"-shaped seal 1, and rectangular holes are opened on the vertical rails 5-2 for fixing the anti-slip claws 1-1.
[0042] The following example illustrates the installation of the anti-slip sealing system of the present invention.
[0043] When pre-installing in the workshop, first install the sealing strip of the sealing slot according to the design requirements, and assemble the anti-slip seal 2 that needs to be installed with the U-shaped sealing strip in advance. At the installation site, after fixing the frame, install the Chinese-shaped seal 1 at the corresponding position of the lower frame 5. Subsequently, fix the anti-slip seal 2 with the U-shaped sealing strip installed at the top of the hook-joint part, and install the anti-slip seal 2 without the sealing strip installed at the bottom of the hook-joint part. Next, put the screws into the countersunk holes 2-3 on the anti-slip seal 2, and fix the anti-slip seal 2 to the corresponding positions at both ends of the hook by means of screws. Finally, place the door and window sashes into the corresponding installation grooves to complete the installation of the sliding doors and windows.
[0044] When the door and window sash is closed, the bottom end of the anti-drop seal 2 installed at the bottom end of the hook contacts the top of the cross-shaped seal 1. The water retaining ribs 1-2 of the cross-shaped seal 1 block the gap at the bottom of the hook and cooperate with the sealing strip to solve the airtightness and watertightness problems at the same time.
[0045] When the door and window sash is closed and locked, under the restriction of the heightening block 2-1, and because the anti-slip seal 2 is installed on the overlapping surface of the indoor hook 3 and the outdoor hook 4, if it is necessary to remove it, it is necessary to unlock it from the interior, stagger the overlapping hooks, remove the screws fixing the anti-slip seal 2, and remove the anti-slip seal 2 at the upper end before the door and window sash can be removed. This prevents the door and window sash from accidentally falling off and from being pried open from the outside, thereby enhancing the anti-theft performance of the sliding door and window.
[0046] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
