Description

Technical Field

[0001] The invention relates to an aluminum alloy door and window for home decoration, in particular to a lifting and sliding door and window with good heat insulation performance. Background Art

[0002] As users' demands for green buildings are getting higher and higher, the structural performance of aluminum alloy doors and windows is changing accordingly. Among them, air tightness and water tightness are one of the more important functions. Traditional aluminum alloy doors and windows have large gaps and are usually sealed with a single rubber strip. In particular, lifting and sliding doors and windows require a lifting action when they are used, so the requirements for thermal insulation and sealing are relatively special. The sealing method that only relies on the upper and lower sliding rubber strips has poor air tightness and water tightness performance and cannot meet the increasing demand. It is difficult for ordinary flat track sliding doors and windows to achieve high water tightness.

[0003] Therefore, how to improve effective air tightness and water tightness is a problem that needs to be solved urgently. Summary of the invention

[0004] The technical problem solved by the present invention is to provide a heat-insulating sealed lifting and sliding door and window with good heat-insulating performance.

[0005] The technical means adopted in the present invention are as follows.

[0006] A heat-insulating sealed lifting and sliding door and window comprises an upward sliding door, a downward sliding door and at least one sliding door leaf that can be pushed and pulled between the two. At least one track mounting position is arranged at the bottom of the upward sliding door leaf, and the two inner side walls of each track mounting position are relatively provided with an upward sliding sealing strip; at least one sealing reinforcement groove is arranged at the top of the downward sliding door leaf, and the two inner side walls of each sealing reinforcement groove are relatively provided with a downward sliding sealing strip; the upper horizontal clamp of the sliding door leaf is arranged between the two upward sliding sealing strips, and the bottom surface of the lower horizontal clamp of the sliding door leaf is connected with at least one first sealing member; it also comprises at least one supporting profile, and the upper end of the supporting profile is fixed to the lower horizontal clamp; when the sliding door leaf is closed, the bottom of the first sealing member is tightly pressed on the downward sliding door leaf, and the lower end of the supporting profile is inserted between the two downward sliding sealing strips of the sealing reinforcement groove; when the sliding door leaf is opened, the first sealing member moves upward away from the downward sliding door leaf, and the lower end of the supporting profile is not inserted between the two downward sliding sealing strips of the sealing reinforcement groove.

[0007] Furthermore, each sliding door corresponds to one track installation position, one sealing reinforcement groove and one supporting profile.

[0008] Furthermore, the bottom surface of each lower horizontal portion includes a first snap groove, the top of the first seal is a first snap portion that cooperates with the first snap groove and is fixed thereto, and the bottom of the first seal is a clamping portion. When the bottom of the first seal is pressed downwardly on the lower slide, the bottom surface of the clamping portion elastically deforms upwardly.

[0009] Furthermore, the first sealing member is a plastic member, and the bottom surface of the pressing portion is a downwardly protruding arc-shaped structure or a rounded structure.

[0010] Furthermore, a descending slide rail is provided on the upper surface of the slide, and a second sealing member is provided at the bottom of the hook sealing plate of the push-pull fan. A groove matching the descending slide rail is provided at the bottom of the second sealing member. A sealing strip is also connected to the bottom of the second sealing member, which is connected to a connection groove preset at the bottom of the second sealing member. When the push-pull fan is closed, the bottom of the sealing strip is pressed on the descending slide and the descending slide rail.

[0011] Furthermore, a second snap groove is provided on the lower horizontal part, the top of the support profile is a second snap portion, and the second snap portion is fastened in the second snap groove to connect the support profile to the lower horizontal part, and the bottom of the support profile is a thin plate structure.

[0012] Furthermore, it also includes a cover plate, which is installed at the stepped structure of the downward slide to form a non-stepped structure on the top surface of the downward slide, and a cover plate drainage hole is provided on the cover plate at a position corresponding to the downward drainage part.

[0013] Preferably, it also includes a drainage component, the indoor and outdoor sides of which are snap-on structures that cooperate with the lower slide, so that the drainage component is installed on the lower slide and clamped between the cover plates at both ends. The drainage component is provided with a lower concave slope on the outdoor side, which forms a drainage channel connecting the upper surface of the lower slide and the outdoor side surface. The drainage channel is independent and is not connected to the chamber formed by the lower slide and the cover plate.

[0014] Furthermore, three equidistant positioning walls are extended downward from the bottom of the upper slide, and two track mounting positions are formed between the three positioning walls. An upper slide track is provided in each track mounting position, and an upper pulley assembly is provided at a position of the upper horizontal plane corresponding to the upper slide track; a lower slide rail is provided on the upper surface of the lower slide, and a lower pulley assembly is provided at a position of the lower horizontal plane corresponding to the lower slide rail.

[0015] Furthermore, the pulley in the upper pulley assembly adopts an anti-swing wheel.

[0016] Furthermore, the first sealing member is clamped on the side of the light seal of the push-pull fan, and when the push-pull fan is closed, the light seal and the side seal are tightly sealed by the first sealing member.

[0017] The technical effects produced by the present invention are as follows.

[0018] 1. The present invention adds three components to enhance the sealing between the lower horizontal and the lower sliding. The first is to add a first sealing member with a certain elastic deformation ability. The first sealing member that can be deformed to a small extent fills the gap of the traditional aluminum alloy door, effectively ensuring the air tightness, water tightness and other sealing effects of the whole door; the second is to preset a sealing reinforcement groove on the lower sliding, and add a supporting profile for use in conjunction, and use the supporting profile to further seal the gap between the lower horizontal and the lower sliding; the third is to set a second sealing member at the bottom of the hook-and-seal plate, which can effectively improve the air tightness and waterproof performance of the bottom of the hook-and-seal plate when the sliding door is closed. When the sliding door and window are closed, the above three components are added and used in combination to fill the gap of the traditional aluminum alloy door, effectively ensuring the air tightness, water tightness, heat insulation and other sealing effects of the whole door.

[0019] 2. The slide in the present invention adopts a flat track and no-step design, which can effectively avoid the trouble of tripping and achieve a safety effect.

[0020] 3. The present invention uses a plurality of sealing strips to cooperate in sliding up and sliding down, which perfectly reflects the sealing performance of the entire door.

[0021] 4. The present invention provides an independent drainage component, which can maintain the discharge speed even when the amount of rainwater is large, avoid water accumulation, and prevent rainwater from entering the interior of the slide. It can also avoid the accumulation of water in the slide, improve water tightness, and avoid adverse consequences caused by internal moisture. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention provides a heat-insulating sealed lifting and sliding door and window, comprising an upper slide 1, a lower slide 2 and a sliding sash 3 therebetween, wherein the sliding sash 3 is pushed and pulled by sliding on a slide rail relatively arranged between the upper slide 1 and the lower slide 2. The following is a detailed description of an embodiment comprising two inner and outer sliding sashes, wherein the structures of the two sliding sashes are the same, and the directions of the two sliding sashes are different only because of different pushing and pulling directions.

[0034] like Figure 2 , Figure 4 As shown, the upper slide 1 includes an upper slide inner frame 11 on the indoor side and an upper slide outer frame 12 on the outdoor side, and the upper slide inner frame 11 and the upper slide outer frame 12 are connected by an upper slide heat insulation strip 13. Three equidistant positioning walls 14 are extended downward from the bottom of the upper slide inner frame 11 and the upper slide outer frame 12, and two track mounting positions 10 are formed between the three positioning walls 14, and each track mounting position 10 is provided with an upper slide track 15. In the above structure, the position of the upper slide heat insulation strip 13 is required not to affect the upper slide track 15 and the middle positioning wall 142. Upper slide sealing strips 16 are provided on the opposite sides of the positioning wall 14, which are respectively fixed in the preset card grooves of the positioning wall 14.

[0035] The lower slide 2 comprises an inner lower slide frame 21 on the indoor side and an outer lower slide frame 22 on the outdoor side. The inner lower slide frame 21 and the outer lower slide frame 22 are connected by a lower lower heat insulation strip 23 .

[0036] like Figure 2 , Figure 5 As shown, the downward sliding outer frame 22 is usually provided with an inclined drainage portion 221, which is provided with an outer frame drainage hole 222, so as to collect and drain rainwater on the outer fan when it rains, and discharge it to the outside of the room. In the present invention, in order to achieve both drainage and sealing performance between the inner and outer fans and the downward sliding door, the downward sliding door 2 adopts a flat track non-step structure. Specifically, it also includes a cover plate 7, which is fixed on the drainage portion 221 of the downward sliding outer frame 22, so that the top surface of the downward sliding door 2 is a horizontal non-step structure, and the cover plate drainage hole 71 is also provided on the cover plate 7. The provision of such a hidden drainage system ensures the water tightness of the entire door.

[0037] The drainage hole 71 may be a prefabricated hole on the cover plate 7. More preferably, an independent auxiliary drainage member 72 is provided, such as Fig. 9 and Fig.10 In the structure shown, the indoor side and outdoor side of the drainage member 72 are respectively buckle structures that cooperate with the lower slide 2, so that the drainage member 72 can be buckled and installed on the lower slide 2, and the two ends of the drainage member 72 are adjacent to the cover plate 7, that is, the two cover plates 7 sandwich it in the middle, and the upper surface of the drainage member 72 is preferably flush with the upper surface of the cover plate 7. The drainage member 72 is provided with a concave slope on the outdoor side, which forms a drainage channel 721 connecting the upper surface and the outdoor side. The drainage channel 721 is independent and does not communicate with the chamber formed by the lower slide 2 and the cover plate 7. The drainage member 72 is provided with a perforation, and it is screwed and fixed to the lower slide 2 by a connecting member such as a screw. When installing, the drainage member 72 and the cover plate 7 are in a manner of being adjacent and pressed. With such an independent drainage member, rainwater on the upper surface of the lower slide 2 is discharged to the outdoor side of the lower slide through the drainage channel 721, and the discharge speed can be maintained even when the amount of rainwater is large to avoid water accumulation, and rainwater will not enter the inside of the lower slide, and the situation of water accumulation inside the lower slide can also be avoided, thereby improving water tightness and avoiding adverse consequences caused by internal moisture.

[0038] Two sealing reinforcement grooves 24 corresponding to the two sliding fans 3 are provided on the lower slide 2, and corresponding lower slide sealing strips 26 are provided on the inner and outer sides of the sealing reinforcement grooves 24. Two lower slide rails 25 corresponding to the two sliding fans 3 are provided on the upper surface of the lower slide 2, and the lower slide rails 25 are located on the indoor side of the sealing reinforcement grooves 24, which is more conducive to heat insulation sealing and protection of the slide rails and pulleys.

[0039] The arrangement of the cover plate 7 does not affect the arrangement of the sealing reinforcement groove 24 and the lower sliding rail 25. The sealing reinforcement groove 24 can be arranged on the lower sliding inner frame 21 and the lower sliding outer frame 22, or it can also be arranged in the embodiment shown in the figure. The sealing reinforcement groove 24 corresponding to the inner fan is formed by the relative arrangement of the lower sliding inner frame 21 and the cover plate 7. Specifically, a snap groove is extended downward from the indoor end of the cover plate 7, and a corresponding snap groove is arranged on the outdoor side of the lower sliding inner frame 21.

[0040] The top thickness of the upper cross section 31 of the sliding door 3 matches the spacing between the two upper sliding sealing strips 16 in the track mounting position, and an upper pulley assembly 5 extending into the upper sliding track 15 is provided at the top of the upper cross section 31. The pulley assembly 5 can use an anti-sway wheel as shown in the figure to prevent the shaking of the door leaf and increase the rolling force of the door leaf, so that the entire door leaf can be pushed without resistance and is easier to push and pull.

[0041] The bottom center of the lower crossbar 32 is a cavity opening downward, which is used to install the lower pulley assembly 6. Another key point of the present invention is to arrange a first sealing member 4 between the lower crossbar 32 and the contact surface of the lower pulley. Figure 2 , Figure 3 and Figure 6As shown, the first snap groove 321 is reserved on the inner and outer sides of the bottom surface of the lower cross 32, and the first seal 4 is installed on the first snap groove 321. The top of the first seal 4 is the first snap portion 41 that is fastened with the first snap groove 321, and the bottom of the first seal 4 is the pressing portion 42, which can be a protruding arc structure or a rounded structure. When the bottom of the first seal 4 is pressed on the top surface of the lower slide 2, the pressing portion 42 at the bottom of the first seal 4 is squeezed and elastically deformed upward, increasing the contact area between the bottom surface of the pressing portion 42 and the top surface of the lower slide 2, so as to achieve the function of strengthening the sealing. Therefore, it is better to select a plastic part with both small deformation and hardness for the first seal 4, and of course other materials with a certain deformation can also be used.

[0042] A second buckle groove 322 is reserved on the side wall of the cavity at the bottom of the lower crossbar 32. In order to enhance the sealing performance, another key point of the present invention is to add a support profile 8, such as Figure 2 , Figure 3 class Figure 7 As shown, the upper part of the support profile 8 is provided with a snap portion 81 matching the second snap groove 322 , and the lower part thereof is a thin plate structure 82 , which can be movably inserted between the two lower sliding sealing strips 26 of the sealing reinforcement groove 24 .

[0043] The bottom of the lower pulley assembly 6 is preset with a recess that matches the lower slide rail 25 , or the bottom of the lower pulley assembly 6 is connected to a soft sealing belt 61 , and the sealing belt 61 is also preset with a recess that matches the lower slide rail 25 .

[0044] Each of the above-mentioned sliding doors 3 corresponds to one track installation position 10 , one sealing reinforcement groove 24 and one supporting profile 8 .

[0045] like Fig. 9 and Fig.11 As shown, a second sealing member 33 is installed at the bottom of the hook-shaped sealing plate of the push-pull fan 3, and is fixed by passing a fixing member such as a screw through a preset through hole on it. A groove 331 matching the lower slide rail 25 is provided at the bottom of the second sealing member 33, and a sealing strip is also connected to the bottom of the second sealing member 33, which is fixed to the bottom of the second sealing member 33 through a connection groove 332 preset at the bottom. After the second sealing member 33 is provided, the air tightness and waterproof performance of the bottom of the hook-shaped sealing plate can be effectively increased.

[0046] like Figure 2As shown, when the lifting and sliding door and window of the present invention is in the closed state, the window sash falls on the lower slide, and the upper crossbar 31 does not leave the track installation position, and is sandwiched between the two upper slide sealing strips 16 to keep the track installation position airtight; the lower crossbar 32 is tightly pressed on the top surface of the lower slide 2 through the first sealing member 4, and at the same time, the thin plate structure 82 of the supporting profile 8 is inserted into the corresponding pair of lower slide sealing strips 26, and at the same time, the concave part at the bottom of the lower pulley assembly 6 is pressed on the lower slide rail 25. In this use state, the downward movement of the window sash can effectively enhance the air tightness and water tightness of the entire door, and the pulley is lifted up while the window sash moves downward, which reduces the pulley from being depressed due to long-term stay, and can effectively extend the service life of the pulley.

[0047] like Figure 3 As shown, when the lifting and sliding door and window of the present invention is in the open state, the window sash is lifted, the upper crossbar 31 is still located in the track installation position, and the upper pulley assembly 5 is lifted up to cooperate with the upper slide track 15 to slide, and the track installation position is still kept airtight; the first sealing member 4 at the bottom of the lower crossbar 32 leaves the top surface of the lower slide 2, and at the same time, the thin plate structure 82 of the supporting profile 8 leaves a pair of lower slide sealing strips 26 upward, and at the same time, the concave part of the lower pulley assembly 6 leaves the lower slide rail 25, leaving only the pulley 62 in the pulley assembly 6 to slide on the lower slide rail 25. After opening, the separation of the window sash and the window frame makes the entire door sash push and pull more smoothly, and it can be positioned and closed at any time, and the load-bearing capacity of a single sash can reach 300 kg.

[0048] The first sealing member 4 is not only disposed at the bottom of the lower cross section 32 to enhance the sealing performance, but can also be applied to other locations. Figure 7 Another cross-sectional position of the sliding door and window is shown, and the side of the light support 91 can also be pressed against the edge seal 92 through the first seal 4, and its structural features are similar to those described above, and will not be described in detail. Such a setting can maximize the thermal insulation and sealing performance of the sliding door and window.
