AI Technical Summary
In existing guide rail structures with built-in louvered insulated glass, the screw fixing method is prone to loosening, causing the locking teeth to lose stable fixation and fail to accurately engage with the magnetic control handle. Furthermore, it is prone to swaying under strong wind loads outdoors, affecting operational safety and stability.
The first and second profiles, which are hooked together with the pressure wire assembly, use a hook structure with arc-shaped snap-fit parts and limit protrusions to replace the traditional screw fixation, ensuring a stable connection of the serrated strip. The aluminum alloy base also improves the load-bearing capacity and sealing performance.
This design achieves a secure installation of the serrated strip, avoids screw loosening issues, enhances the load-bearing capacity and sealing performance of the guide rail structure, and ensures smooth opening and closing and safety of the louvers.

Description
Technical Field
[0001] This utility model relates to the field of built-in louvered insulated glass technology, specifically to a composite guide rail structure for built-in louvered insulated glass. Background Technology
[0002] Built-in blinds insulated glass combines the advantages of both heat and sound insulation with the sunshade and adjustment functions of built-in blinds. Its core principle involves a magnetic handle on the outside of the glass and an internal magnet assembly on the inside, which magnetically attracts the controller's built-in magnets. This magnetic attraction causes the controller to rise and fall, thus controlling the opening and closing of the blinds. A guide rail, serving as the magnetic handle's running track, provides a precise sliding trajectory, ensuring smooth opening and closing of the blinds while limiting its range of motion to prevent deviation, jamming, or collisions during operation, ensuring both ease of operation and safety.
[0003] Based on the above, the inventors have discovered the following problems: the retaining teeth in current guide rails are generally fixed with screws. The threaded connection between the screws and the guide rail relies on the friction between the metals to maintain tightness. However, when the built-in louvers are adjusted, the magnetic control handle drives the retaining teeth to slide along the guide rail, which generates high-frequency micro-vibrations. At the same time, strong outdoor wind loads will cause the guide rail and glass to sway laterally, causing the thread gap between the screws and the guide rail to gradually widen and show a tendency to loosen. After long-term use, the screws loosen, causing the retaining teeth to lose stable fixation. When the magnetic control handle slides, the retaining teeth will move up and down and cannot accurately engage with the stop bar of the magnetic control handle.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a composite guide rail structure with built-in louvers and hollow glass, in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this invention is to provide a composite guide rail structure with built-in louvered hollow glass to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A composite guide rail structure for hollow glass with built-in louvers includes a first profile, a second profile, and a pressure wire assembly. The pressure wire assembly includes a guide rail, on which are provided a first extension arm, an arc-shaped locking part, a second extension arm, a limiting protrusion, a second groove, a plate, and a serrated retaining strip. Both ends of the plate are provided with breaks. A serrated retaining strip is slidably disposed between the guide rail and the plate. A through groove is formed on the plate, and a retaining groove is formed on the serrated retaining strip. One end of the retaining groove passes through the through groove of the plate and protrudes into the guide space of the guide rail. The longitudinal section of the serrated retaining strip is "T"-shaped, the distance between the two breaks is consistent with the length of the serrated retaining strip, and the opposite sides of the two breaks are respectively attached to the outer walls of the two ends of the serrated retaining strip.
[0007] Furthermore, the first profile includes a first base, with a protrusion and a snap-fit portion on one side of the first base, both the protrusion and the snap-fit portion being hook-shaped at the ends away from the first base; the second profile includes a second base, with a second sealing groove and a first groove on the second base; one end of the arc-shaped snap-fit portion hooks into the snap-fit portion, and one end of the limiting protrusion portion hooks into the protrusion portion, and the first and second profiles are specifically door and window profiles.
[0008] The beneficial effect of adopting the above-mentioned further solution is that, through the hook-fitting first profile, second profile and pressure wire assembly, when the arc-shaped locking part hooks with the locking part, one end of the limiting protrusion hooks with the protrusion, thereby realizing a stable connection between the first profile, second profile and pressure wire assembly, and improving the load-bearing capacity after the serrated clip is installed and fixed.
[0009] Furthermore, both the first and second extension arms are perpendicular to the guide rail, and a receiving space is formed between the first and second extension arms; the arc-shaped snap-fit part is provided at the end of the first extension arm away from the guide rail, and the limiting protrusion part is provided at the end of the second extension arm away from the guide rail.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the accommodating space formed between the first extension arm and the second extension arm can provide sufficient installation clearance for the cooperation of the first profile, the second profile and the pressure wire assembly, ensuring that the hook structure, namely the arc-shaped snap-fit part and the snap-fit part, and the limiting protrusion part and the protrusion part, can hook together.
[0011] Furthermore, the limiting protrusion is arranged opposite to the protrusion, the limiting protrusion is outwardly convex hook-shaped, the arc of the arc-shaped locking part is 90 degrees-120 degrees, and the end of the arc-shaped locking part is rounded hook-shaped.
[0012] The beneficial effect of adopting the above-mentioned further solution is that the limiting protrusion is outwardly hook-shaped and is arranged opposite to the protrusion, which can form a reverse hook with the protrusion, enhance the locking effect, and prevent the first profile from separating from the pressure wire assembly; the arc of the arc-shaped snap-fit part is 90°-120° and the end is rounded hook-shaped, which can ensure a tight fit with the snap-fit part.
[0013] Furthermore, a second groove is provided on the first extension arm, the second groove is arranged opposite to the first groove, and a hollow glass is engaged between the second groove and the first groove, and the hollow glass is provided with louvers inside.
[0014] The beneficial effect of adopting the above-mentioned further solution is that the second groove is arranged opposite to the first groove and engages with the insulated glass with built-in louvers, which can clamp and fix the insulated glass with built-in louvers from both sides, ensuring the accurate position of the insulated glass with built-in louvers.
[0015] Furthermore, the first substrate is provided with two first sealing grooves, and a sealing strip is installed in each of the two first sealing grooves. There are two second sealing grooves, and the two sealing strips are respectively embedded in the two second sealing grooves at the ends away from the first sealing grooves.
[0016] The beneficial effect of adopting the above-mentioned further solution is that the two first sealing grooves and the two second sealing grooves are fitted together by the corresponding sealing strips to form a double-layer sealing structure, which can significantly improve the sealing performance of the insulating glass. The outer sealing strip blocks most of the rainwater and air penetration, and the inner sealing strip further blocks residual leakage.
[0017] Furthermore, both the first substrate and the second substrate are made of aluminum alloy.
[0018] The beneficial effect of adopting the above-mentioned further solution is that, since the first substrate and the second substrate are made of aluminum alloy, aluminum alloy has the characteristics of high strength and light weight; spraying the surface of the first substrate and the second substrate can improve the corrosion resistance, wear resistance and weather resistance of the first substrate and the second substrate.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The built-in louvered hollow glass composite guide rail structure achieves a stable connection between the first profile, the second profile, and the pressure wire assembly through hook-and-fitting first profile, second profile, and pressure wire assembly, improving the load-bearing capacity after the serrated clip is installed and fixed; due to the punched breaks at both ends of the plate, the snap-fit installation of the breaks at both ends of the plate with the T-shaped serrated clip replaces the traditional screw fixing. During production, workers can directly insert the serrated clip into the breaks and use the T-shaped structure for self-locking, improving the installation stability of the serrated clip; when the stop bar of the locking component on the magnetic control handle outside the built-in louvered hollow glass is engaged in the slot of the serrated clip, the position of the magnetic control handle is locked, avoiding the loosening problem that may occur with traditional bolt connections, and ensuring that the serrated clip will not be displaced or shaken due to load impact during long-term use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-7This utility model provides a technical solution: a composite guide rail structure with built-in louvered hollow glass, including a pressure wire assembly 3; the pressure wire assembly 3 has a guide rail 31, on which are provided a first extension arm 32, an arc-shaped locking part 33, a second extension arm 34, a limiting protrusion 35, a second groove 36, a plate 37, and a serrated locking strip 39. Both ends of the plate 37 are provided with breaks 38. The serrated locking strip 39 is slidably arranged between the guide rail 31 and the plate 37. The plate 37 has a through groove, and the serrated locking strip 39 has a locking groove. One end of the locking groove passes through the through groove of the plate 37 and protrudes into the guide space of the guide rail 31. The longitudinal section of strip 39 is T-shaped. The distance between the two breaks 38 is the same as the length of the serrated strip 39, and the opposite sides of the two breaks 38 are respectively attached to the outer walls of both ends of the serrated strip 39. Since the two ends of the plate 37 are punched with breaks 38, the snap-fit installation of the two ends of the plate 37 and the T-shaped serrated strip 39 replaces the traditional screw fixing. During production, workers can directly insert the serrated strip 39 into the breaks and use the T-shaped structure to lock itself, which improves the installation stability of the serrated strip 39. When the locking component of the magnetic control handle outside the central control glass is inserted into the slot of the serrated strip 39, the position of the magnetic control handle is locked.
[0024] Please see Figure 2This utility model provides a technical solution: a first profile 1 includes a first base 11, with a protrusion 14 and a snap-fit portion 15 on one side of the first base 11. Both the protrusion 14 and the snap-fit portion 15 are hook-shaped at the ends away from the first base 11. A second profile 2 includes a second base 21, with a second sealing groove 22 and a first groove 23 on the second base 21. One end of the arc-shaped snap-fit portion 33 hooks into the snap-fit portion 15, and one end of the limiting protrusion 35 hooks into the protrusion 14. The first extension arm 32 and the second extension arm 34 are both perpendicular to the guide rail 31, and a receiving space is formed between the first extension arm 32 and the second extension arm 34. The arc-shaped snap-fit portion 33 is located at the end of the first extension arm 32 away from the guide rail 31, and the limiting protrusion 35 is located at the end of the second extension arm 34 away from the guide rail 31. The limiting protrusion 35 and the protrusion 14... In terms of relative configuration, the limiting protrusion 35 is outwardly convex and hook-shaped, and the arc-shaped locking part 33 has an arc of 90-120 degrees, with the end of the arc-shaped locking part 33 having a rounded hook shape; the second extension arm 34 is directly connected to the guide rail 31, with no gap at the connection point, forming a rigid direct connection structure without any compression space. Therefore, when the end of the limiting protrusion 35 hooks with the protrusion 14 of the first profile 1, it mainly bears the longitudinal stabilizing force, which is suitable for areas with small vertical loads in insulated glass with built-in blinds; the first extension arm 32 is directly connected to the guide rail 31, but a compression space is reserved at the connection point. This space can provide a slight buffer when the arc-shaped locking part 33 hooks with the locking part 15 to receive force, avoiding component damage caused by rigid collision; the arc of the arc-shaped locking part 33 is 90 degrees, and its hooking cooperation with the locking part 15, combined with the buffering effect of the compression space, can adapt to slight lateral vibrations.
[0025] Please see Figure 3This utility model provides a technical solution: a first profile 1 includes a first base 11, with a protrusion 14 and a snap-fit portion 15 on one side of the first base 11, both the protrusion 14 and the snap-fit portion 15 being hook-shaped at the ends away from the first base 11; a second profile 2 includes a second base 21, with a second sealing groove 22 and a first groove 23 on the second base 21; one end of the arc-shaped snap-fit portion 33 is hooked to the snap-fit portion 15, and one end of the limiting protrusion 35 is hooked to the protrusion 14; the first extension arm 32 and the second extension arm 34 are both arranged perpendicular to the guide rail 31, and a receiving space is formed between the first extension arm 32 and the second extension arm 34; the arc-shaped snap-fit portion 33 is located at the end of the first extension arm 32 away from the guide rail 31, and the limiting protrusion 35 is located at the end of the second extension arm 32 away from the guide rail 31. At the end of arm 34 furthest from guide rail 31, a limiting protrusion 35 is positioned opposite to protrusion 14. The limiting protrusion 35 is in the shape of an outwardly protruding hook, and the arc of the arc-shaped locking part 33 is 90-120 degrees. The end of the arc-shaped locking part 33 is in the shape of a rounded hook. The second extension arm 34 is directly connected to guide rail 31, and a compression space is provided at the connection. When the limiting protrusion 35 and protrusion 14 are hooked together to bear vertical loads, this space can disperse stress through slight deformation, which is suitable for the parts of the insulated glass with built-in louvers that have a large self-weight. The first extension arm 32 is directly connected to guide rail 31 without compression space, forming a rigid support structure. After the arc-shaped locking part 33 hooks with the locking part 15, it can provide stronger lateral tensile strength, preventing the insulated glass with built-in louvers from lateral displacement under strong wind loads.
[0026] Please see Figure 4This utility model provides a technical solution: a first profile 1 includes a first base 11, with a protrusion 14 and a snap-fit portion 15 on one side of the first base 11, both the protrusion 14 and the snap-fit portion 15 being hook-shaped at the ends away from the first base 11; a second profile 2 includes a second base 21, with a second sealing groove 22 and a first groove 23 on the second base 21; one end of the arc-shaped snap-fit portion 33 is hooked to the snap-fit portion 15, and one end of the limiting protrusion 35 is hooked to the protrusion 14; the first extension arm 32 and the second extension arm 34 are both perpendicular to the guide rail 31, and a receiving space is formed between the first extension arm 32 and the second extension arm 34; the arc-shaped snap-fit portion 33 is located at the end of the first extension arm 32 away from the guide rail 31, and the limiting protrusion 35 is located at the end of the second extension arm 34 away from the guide rail 31. At one end away from the guide rail 31, the limiting protrusion 35 is positioned opposite to the protrusion 14. The limiting protrusion 35 is in the shape of an outwardly protruding hook, and the arc-shaped locking part 33 has an arc of 90-120 degrees, with the end of the arc-shaped locking part 33 having a rounded hook shape. The second extension arm 34 is directly connected to the guide rail 31 without any compression space. The first extension arm 32 is also directly connected to the guide rail 31 without any compression space. Both form a high-strength rigid structure that can simultaneously withstand large vertical loads and lateral tensions, making it suitable for corners of insulated glass with built-in louvers or high wind pressure areas. The arc-shaped locking part 33 has an arc of 120 degrees and forms a tight hook with the locking part 15. Combined with the rigid support without compression space, the overall deformation resistance is significantly improved. The hook-fitting of the limiting protrusion 35 and the protrusion 14 further enhances the longitudinal stability.
[0027] Please see Figure 7 This utility model provides a technical solution: the guide rail 31 does not have a first extension arm 32 and a second extension arm 34. A plate 37 is installed inside the guide rail 31. Both ends of the plate 37 are provided with breaks 38. A serrated strip 39 is slidably provided between the guide rail 31 and the plate 37. A through groove is opened on the plate. One end of the serrated strip 39 with the groove extends through the through groove of the plate 37 to the outside of the guide rail 31. The longitudinal section of the serrated strip 39 is "T" shaped. The distance between the two breaks 38 is the same as the length of the serrated strip 39, and the opposite sides of the two breaks 38 are respectively attached to the outer walls of the two ends of the serrated strip 39.
[0028] Please see Figure 1-7This utility model provides a technical solution: a second groove 36 is provided on the first extension arm 32, the second groove 36 is arranged opposite to the first groove 23, and an insulated glass is engaged between the second groove 36 and the first groove 23. The insulated glass has louvers inside. The first base 11 is provided with two first sealing grooves 12, and a sealing strip 13 is installed in each of the two first sealing grooves 12. There are two second sealing grooves 22, and the two sealing strips 13 are respectively embedded in the two second sealing grooves 22 at the ends away from the first sealing grooves 12. The first base 11 and the second base 21 are both made of aluminum alloy. The two first sealing grooves 12 and the two second sealing grooves 22 are correspondingly engaged by the sealing strips 13 to form a double-layer sealing structure, which can significantly improve the sealing performance of the insulated glass with built-in louvers. The outer sealing strip 13 blocks most of the rainwater and air penetration, and the inner sealing strip 13 further blocks residual leakage. Since the first base 11 and the second base 21 are made of aluminum alloy, aluminum alloy has the characteristics of high strength and light weight.
