Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a track-pressing installation structure and an inward tilting sliding window. Background Technology

[0002] Aluminum alloy doors and windows are widely used in the construction industry due to their excellent performance, such as corrosion resistance, high strength, and lightweight. Inward-tilting sliding windows, as an innovative type of aluminum alloy door and window, combine the advantages of casement and sliding windows. They can achieve both inward tilting for micro-ventilation and side-sliding opening without occupying interior space, meeting users' diverse needs for ventilation, lighting, and space utilization, and are becoming increasingly popular in modern architecture.

[0003] Referring to a high-sealing inward-tilting sliding window with patent publication number CN222759691U, existing inward-tilting sliding windows have some problems in the design and installation of the opening track joists. Because the horizontal track of an inward-tilting sliding window needs to avoid sliding hardware (such as pulleys), the structural design of the horizontal track and the vertical frame differs significantly. This design results in insufficient overlap of the horizontal track joists after installation in some products, easily leading to gaps between the joists and the window frame and glass. These gaps allow air and rainwater to leak in, directly affecting the window's sealing performance, stability, and lifespan. For example, in strong winds or heavy rain, rainwater may seep into the room through these gaps, causing dampness on interior walls and floors, and even leading to leaks. Furthermore, loose overlaps can cause the joists to loosen or deform during frequent use, further reducing the window's performance. Utility Model Content

[0004] The purpose of this utility model is to provide a track-mounted pressure line installation structure and an inward tilting sliding window. By adding track auxiliary materials to assist the horizontal track pressure line in overlapping, a tight overlap between the pressure line and the window frame and glass is achieved, which improves the window's sealing performance, stability and service life.

[0005] In a first aspect, this utility model provides a track pressing and mounting structure, comprising:

[0006] A horizontal rail profile includes an integrally formed glass mounting part and a slide rail part, wherein the glass mounting part is used to place glass, and the extension height of the glass mounting part is greater than the extension height of the slide rail part;

[0007] A pulley assembly is provided on the slide rail section;

[0008] The track accessory has one end located on the glass mounting part and the other end extending above the pulley assembly. The track accessory also has one of a mounting slot and a mounting block on the side facing away from the pulley assembly.

[0009] The horizontal rail pressure line has one of a mounting slot and a mounting block on the side facing the rail accessory. The mounting block is detachably installed in the mounting slot, and the horizontal rail pressure line can press and fix the glass.

[0010] The track clamping installation structure provided by this utility model, by setting track accessories on the glass mounting part, with the other end of the track accessories extending above the pulley assembly, avoids the pulley assembly and provides a stable and reliable installation position for the horizontal track clamping line. The horizontal track clamping line is fixed to the track accessories by mounting slots and mounting blocks, thereby completing the clamping and fixing of the glass. This structural design ensures a tight overlap between the horizontal track clamping line, the horizontal track profile, and the glass, significantly improving the sealing performance, effectively preventing air and rainwater leakage, and enhancing the overall performance and service life of the window.

[0011] Furthermore, the track accessory is provided with a first mounting plate on the side facing the glass mounting part, and a first mounting point is provided at the end of the first mounting plate away from the glass. The glass mounting part is provided with a second mounting plate, and a second mounting point is provided at the end of the second mounting plate facing the glass. The first mounting point can be inserted into the side of the second mounting point away from the glass to fix the track accessory to the glass mounting part.

[0012] By employing the above technical solution, a secure connection is formed between the track lining and the glass mounting section through the cooperation of the first and second mounting points. This locking point design ensures that the track lining will not loosen or shift after installation, enhancing the overall structural stability.

[0013] Furthermore, the track accessory is provided with a first support foot on the side facing the glass mounting part, the first support foot being used to abut against the glass mounting part; and / or, the glass mounting part is provided with a second support foot on the side facing the track accessory, the second support foot being used to abut against the track accessory.

[0014] By employing the above technical solution, a first support foot is provided on the track material, and a second support foot is provided on the glass mounting part. The two support feet abut against each other, providing additional physical support. This design ensures a tight contact between the track material and the glass mounting part, reducing loosening or displacement caused by external forces.

[0015] Furthermore, the track auxiliary material is provided with a first mounting hole, and the glass mounting part is provided with a second mounting hole. The first mounting hole and the second mounting hole can be aligned with each other so that the fixing screw can pass through the first mounting hole and the second mounting hole in sequence.

[0016] By adopting the above technical solution, a first mounting hole and a second mounting hole are respectively set on the track auxiliary material and the glass mounting part, and fixed screws are used for connection, ensuring a firm connection between the track auxiliary material and the glass mounting part.

[0017] Furthermore, there are multiple first mounting holes and multiple second mounting holes. The multiple first mounting holes are spaced apart along the length extension direction of the track auxiliary material, and the multiple second mounting holes are spaced apart along the length extension direction of the glass mounting part.

[0018] By employing the above technical solution, and by setting multiple mounting holes on the track lining and the glass mounting section, and using multiple fixing screws for connection, the fixing strength between the track lining and the glass mounting section is significantly enhanced. This multi-point fixing method can evenly distribute external forces, reducing loosening or deformation caused by excessive local stress.

[0019] Furthermore, it also includes a foaming glue stick, and the mounting slot is provided with a snap-fit ​​block. The opposite ends of the mounting slot are respectively provided with a glue stick groove and a snap-fit ​​groove. The foaming glue stick is detachably disposed in the glue stick groove. The foaming glue stick can abut against the side wall of the mounting slot so that the snap-fit ​​block is inserted into the snap-fit ​​groove.

[0020] By employing the above technical solution, the foaming adhesive rod abuts against one side of the mounting slot, thereby pressing the buckle block on the other side into the buckle slot, achieving a tight connection between the mounting block and the mounting slot. This design not only enhances the connection strength between the horizontal rail pressure line and the track auxiliary material, but also further improves the sealing performance through the elastic filling effect of the foaming adhesive rod, effectively preventing the leakage of air and rainwater.

[0021] Furthermore, it includes a vertical frame profile and a vertical frame pressure line. The vertical frame profile is vertically disposed on the horizontal rail profile. The vertical frame pressure line abuts against the surface of the horizontal rail pressure line away from the track auxiliary material, so as to press the horizontal rail pressure line tightly onto the track auxiliary material.

[0022] Using the above technical solution, the vertical frame trim and horizontal rail trim only require 90-degree cutting and installation, eliminating the need for other complex processing. This design significantly simplifies the profile processing steps, reducing processing costs and installation time. Furthermore, the 90-degree cutting installation method ensures a tight fit between the vertical frame trim and the horizontal rail trim, guaranteeing a secure connection between the trim and the window frame and glass. This not only further improves the window's sealing performance, effectively preventing air and rainwater leakage, but also ensures the window's airtightness and watertightness, enhancing overall performance and service life.

[0023] Furthermore, it also includes a cover plate, and both the track material and the vertical frame pressure line are provided with cover plate locking points on the side away from the glass. The cover plate is provided with a cover plate locking groove, and the cover plate locking points can be engaged and fixed in the cover plate locking groove so that the cover plate respectively covers the track material and the vertical frame pressure line.

[0024] By employing the above technical solution, cover plate locking points are set on the track lining and vertical frame pressure lines, and these points cooperate with the cover plate slots to achieve concealed installation of the pressure lines. This design makes the connection between the pressure lines and the window frame more discreet, reduces exposed connectors, and improves the overall aesthetics of the window.

[0025] Furthermore, the cover plate on the track auxiliary material is provided with a first splicing angle, and the cover plate on the vertical frame pressure line is provided with a second splicing angle, and the first splicing angle can be spliced ​​with the second splicing angle.

[0026] By adopting the above technical solution, the design of the splicing corners makes the installation between the cover plates more precise. Installers only need to align the first splicing corner with the second splicing corner and splice them together to complete the installation, reducing gaps caused by installation errors.

[0027] Secondly, the present invention provides an inward tilting sliding window, which includes any of the track pressure installation structures described above.

[0028] As can be seen from the above, the track clamping installation structure provided by this utility model, by setting track accessories on the glass mounting part, with the other end of the track accessories extending above the pulley assembly, not only avoids the pulley assembly but also provides a stable and reliable installation position for the horizontal track clamping line. The horizontal track clamping line is fixed to the track accessories by mounting slots and mounting blocks, thereby completing the clamping and fixing of the glass. This structural design ensures a tight overlap between the horizontal track clamping line, the horizontal track profile, and the glass, significantly improving the sealing performance, effectively preventing air and rainwater leakage, and enhancing the overall performance and service life of the window.

[0040] The track pressure line installation structure disclosed in this utility model is mainly used in inward tilting side sliding windows. By adding track auxiliary materials to assist the horizontal track pressure line in overlapping, a tight overlap between the pressure line and the window frame and glass is achieved, which improves the window's sealing performance, stability and service life.

[0041] Reference Appendix Figure 1 In one embodiment, the track pressing installation structure includes a horizontal rail profile 100, a pulley assembly 200, track accessories 300, and a horizontal rail pressing line 400.

The glass mounting part 110 is used to place the glass 115, and the extension height of the glass mounting part 110 is greater than the extension height of the slide rail part 120. The pulley assembly 200 is disposed on the slide rail part 120. One end of the track accessory 300 is disposed on the glass mounting part 110, and the other end of the track accessory 300 extends above the pulley assembly 200.

[0042] Specifically, the horizontal rail pressure line 400 has a detachable adhesive strip on the side facing the glass 115, and the horizontal rail pressure line 400 presses the glass 115 tightly through the adhesive strip. The track auxiliary material 300 is made of high-strength 6063-T6 material, which is not easily deformed, increases the strength of the opening track pressure line, and can provide sufficient support and fixation for the glass 115.

[0043] As can be seen from the above, the track clamping installation structure provided by this utility model, by setting a track accessory 300 on the glass mounting part 110, with the other end of the track accessory 300 extending above the pulley assembly 200, not only avoids the pulley assembly 200 but also provides a stable and reliable installation position for the horizontal track clamping line 400. The horizontal track clamping line 400 is fixed to the track accessory 300 through the mounting slot 310 and the mounting block 320, thereby completing the clamping and fixing of the glass 115. This structural design ensures that the horizontal track clamping line 400, the horizontal track profile 100, and the glass 115 overlap tightly, significantly improving the sealing performance, effectively preventing air and rainwater leakage, and enhancing the overall performance and service life of the window.

[0045] By employing the above technical solution, a secure connection is formed between the track accessory 300 and the glass mounting part 110 through the cooperation of the first mounting point 331 and the second mounting point 112. This locking point design ensures that the track accessory 300 will not loosen or shift after installation, enhancing the stability of the overall structure.

[0046] In one embodiment, the track accessory 300 is further provided with a first support foot 340 on the side facing the glass mounting part 110, the first support foot 340 being used to abut against the glass mounting part 110; and / or, the glass mounting part 110 is further provided with a second support foot 113 on the side facing the track accessory 300, the second support foot 113 being used to abut against the track accessory 300.

The two abut against each other, providing additional physical support. This design ensures a tight contact between the track auxiliary material 300 and the glass mounting part 110, reducing loosening or displacement caused by external forces.

[0048] Reference Appendix Figure 1 Appendix Figure 3 In one embodiment, the device also includes a foaming glue rod 500. The mounting slot 310 is provided with a snap-fit ​​block 311. The mounting slot 320 has a glue rod groove 321 and a snap-fit ​​groove 322 at opposite ends. The foaming glue rod 500 is detachably disposed in the glue rod groove 321. The foaming glue rod 500 can abut against the side wall of the mounting slot 310 so that the snap-fit ​​block 311 is inserted into the snap-fit ​​groove 322.

[0049] By employing the above technical solution, the foaming adhesive rod 500 abuts against one side of the mounting groove 310, thereby pressing the buckle block 311 on the other side into the buckle groove 322, achieving a tight connection between the mounting block 320 and the mounting groove 310. This design not only enhances the connection strength between the horizontal rail pressure line 400 and the track auxiliary material 300, but also further improves the sealing performance through the elastic filling effect of the foaming adhesive rod 500, effectively preventing the leakage of air and rainwater.

[0050] Reference Appendix Figure 4 In one embodiment, the track accessory 300 is provided with a first mounting hole 350, and the glass mounting part 110 is provided with a second mounting hole 114. The first mounting hole 350 and the second mounting hole 114 can be aligned with each other so that the fixing screw can pass through the first mounting hole 350 and the second mounting hole 114 in sequence.

[0051] By adopting the above technical solution, a first mounting hole 350 and a second mounting hole 114 are respectively provided on the track auxiliary material 300 and the glass mounting part 110, and a fixing screw is used for connection, ensuring a firm connection between the track auxiliary material 300 and the glass mounting part 110.

The multiple first mounting holes 350 are spaced apart along the length extension direction of the track auxiliary material 300, and the multiple second mounting holes 114 are spaced apart along the length extension direction of the glass mounting part 110.

[0053] By employing the above technical solution, multiple mounting holes are provided on the track auxiliary material 300 and the glass mounting part 110, and multiple fixing screws are used for connection, significantly enhancing the fixing strength between the track auxiliary material 300 and the glass mounting part 110. This multi-point fixing method can evenly distribute external forces, reducing loosening or deformation caused by excessive local stress.

[0054] Reference Appendix Figure 5 Appendix Figure 6 In one embodiment, it includes a vertical frame profile 600 and a vertical frame pressure line 700. The vertical frame profile 600 is vertically disposed on the horizontal rail profile 100. The vertical frame pressure line 700 abuts against the surface of the horizontal rail pressure line 400 away from the track auxiliary material 300 to press the horizontal rail pressure line 400 onto the track auxiliary material 300.

[0055] Specifically, the vertical frame pressure line 700 is also provided with a detachable adhesive strip on the side facing the glass 115, and the vertical frame pressure line 700 presses the glass 115 tightly through the adhesive strip.

[0056] Using the above technical solution, the vertical frame trim 700 and the horizontal rail trim 400 only require 90-degree cutting and installation, without any other complex processing. This design significantly simplifies the profile processing steps, reducing processing costs and installation time. Furthermore, the 90-degree cutting installation method allows the vertical frame trim 700 and the horizontal rail trim 400 to fit tightly together, ensuring a close fit between the trim and the window frame and glass 115. This not only further improves the window's sealing performance, effectively preventing air and rainwater leakage, but also ensures the window's airtightness and watertightness, enhancing overall performance and service life.

The cover plate locking points 710 can be locked and fixed in the cover plate locking groove 810 so that the cover plate 800 covers the track auxiliary material 300 and the vertical frame pressure line 700 respectively.

[0058] By adopting the above technical solution, cover plate locking points 710 are set on the track auxiliary material 300 and the vertical frame pressure line 700, and they cooperate with the cover plate locking groove 810 to achieve concealed installation of the pressure line. This design makes the connection between the pressure line and the window frame more concealed, reduces exposed connecting parts, and improves the overall aesthetics of the window.

[0059] In one embodiment, the cover plate 800 on the track auxiliary material 300 is provided with a first splicing angle 820, and the cover plate 800 on the vertical frame pressure line 700 is provided with a second splicing angle 830. The first splicing angle 820 can be spliced ​​with the second splicing angle 830.

[0060] By adopting the above technical solution, the design of the splicing angles makes the installation between the cover plates 800 more precise. The installer only needs to align and splice the first splicing angle 820 with the second splicing angle 830 to complete the installation, reducing gaps caused by installation errors.
