Description

Technical Field

[0001] This utility model relates to the technical field of aluminum-plastic door and window profiles, and in particular to an aluminum-plastic door and window profile with enhanced wind pressure resistance. Background Technology

[0002] Window profiles are one of the main components of windows. Currently, the most common and frequently used window and door profiles on the market are plastic profiles (PVC materials), aluminum alloy profiles, and thermally broken aluminum alloy materials.

[0003] Chinese utility model patent CN202023337550.2 discloses a corrosion-resistant aluminum-plastic door and window profile, including a PVC plastic body and a middle frame. A first aluminum alloy profile and a second aluminum alloy profile are embedded on the inner side of the PVC plastic body. The first and second aluminum alloy profiles are connected and riveted together by tenons and mortises. A groove is provided on one side of the PVC plastic body, and a limiting post is connected to the other side surface of the PVC plastic body. A closing buffer device is installed on the inner surface of one side of the PVC plastic body. If the door and window are closed with excessive force, causing collisions between the profiles, the closing buffer device can reduce the closing force between the profiles and increase the stability of the door and window. Polyurethane foam filler is filled between the two tenons on the inner side of the profile. After curing, the polyurethane foam filler has the effects of filling gaps, bonding, sealing, heat insulation, sound absorption, and sealing, increasing the structural stability of the profile and improving the thermal insulation effect.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: aluminum-plastic door and window profiles constructed by wrapping two separate aluminum alloy profiles with PVC plastic have poor connection strength between the aluminum-plastic door and window profiles and the glass, weak wind pressure resistance, and are prone to unstable closure of the profiles, affecting the stability of the doors and windows. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an aluminum-plastic door and window profile with enhanced wind pressure resistance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wind pressure-resistant aluminum-plastic door and window profile, comprising a top plastic profile, a middle aluminum profile, and a bottom plastic profile, wherein the bottom of the top plastic profile is provided with a middle aluminum profile, the bottom of the middle aluminum profile is provided with a bottom plastic profile, a support block is provided inside the top plastic profile, and a plurality of equidistantly distributed pressure-resistant grooves are provided inside the support block, a connecting component is provided between the top plastic profile and the middle aluminum profile, a support component is provided between the middle aluminum profile and the bottom plastic profile, and baffles are provided on both sides of the top of the bottom plastic profile.

[0007] By adopting the above technical solutions, the connection strength between the top plastic profile and the middle aluminum profile can be enhanced by setting up connecting components, and the connection strength between the bottom plastic profile and the middle aluminum profile can be enhanced by setting up supporting components, thereby enhancing the wind pressure resistance and wind pressure strength of aluminum-plastic doors and windows, and improving the stability and service life of doors and windows.

[0008] Furthermore, both ends of the top-molded profile are fixedly connected with locking blocks, which are T-shaped blocks.

[0009] By adopting the above technical solution, the set clips can provide support for the glass, thereby enhancing the wind pressure resistance of aluminum-plastic doors and windows.

[0010] Furthermore, cavities are provided on both sides of the top of the aluminum profile, and positioning grooves are provided inside the aluminum profile, with lightweight foam material filling the positioning grooves.

[0011] By adopting the above technical solution, the cavity set inside the aluminum profile reduces the structural weight while enhancing the compressive strength of the aluminum profile. The lightweight foam material filled in can provide aluminum-plastic doors and windows with high strength and thermal insulation effect.

[0012] Furthermore, the connecting assembly includes a support plate fixedly connected to both sides of the bottom end of the top plastic profile. A limiting block is fixedly connected to the bottom end of the support plate. The limiting block is slidably connected inside the limiting groove. The limiting groove is opened inside the reinforcing seat. The reinforcing seat is fixedly connected to the bottom end of the positioning groove. The support plate is slidably connected to the slot. The slot is opened on both sides of the top of the middle aluminum profile. The limiting block is a trapezoidal block.

[0013] By adopting the above technical solution, the top plastic profile drives the support plate and the limiting block to slide into the limiting groove inside the reinforcing seat. When the limiting block at the bottom of the support plate slides into the limiting groove, filler glue is injected into the limiting groove. The filler glue wraps the support plate and the limiting block with the inside of the limiting groove, thereby restricting the position of the support plate and the limiting block. Then, lightweight foam material is filled into the positioning groove to enhance the connection strength between the top plastic profile and the middle aluminum profile. The filled lightweight foam material can provide high strength and thermal insulation effect for aluminum-plastic doors and windows.

[0014] Furthermore, the connecting assembly also includes filler adhesive filling the inside of the limiting groove, and a groove plug is provided on one side of both the limiting groove and the positioning groove.

[0015] By adopting the above technical solution, the filling adhesive can limit the positioning of the limiting block, while also enhancing the internal support strength of the aluminum profile and improving its wind pressure resistance. The groove plug can also provide protection for the outer side of the aluminum profile.

[0016] Furthermore, the support assembly includes a support member fixedly connected to the top of the bottom plastic profile, and an insert block fixedly connected to the inner wall of the support member. The insert block is engaged with the inside of a slot, and the slot is opened inside both ends of the middle aluminum profile.

[0017] By adopting the above technical solution, the insertion blocks, slots and support components facilitate the connection between the aluminum profile and the plastic profile, while also providing protection for the aluminum profile.

[0018] Furthermore, the support assembly also includes sliding grooves formed on both sides of the top of the bottom plastic profile, a bottom drainage groove is formed at the bottom of the bottom plastic profile, and a top drainage groove is formed on both sides of the top of the bottom plastic profile.

[0019] By adopting the above technical solution, the bottom drainage groove and top drainage groove set on both sides of the bottom plastic profile can drain water completely without leaving any water, thus avoiding freezing and cracking in winter due to water retention.

[0020] Furthermore, the top drainage groove is provided at the connection between the support member and the bottom plastic profile, the top of the support member abuts against the top plastic profile, and the aluminum profile is slidably connected inside the support member.

[0021] By adopting the above technical solution, the set support components can provide support for the top plastic profile and at the same time protect the middle aluminum profile.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. In this application, the top plastic material drives the support plate and the limiting block to slide into the limiting groove inside the reinforcing seat. When the limiting block at the bottom of the support plate slides into the limiting groove, filler is injected into the limiting groove. The filler wraps the support plate and the limiting block with the inside of the limiting groove, thereby restricting the position of the support plate and the limiting block. Then, lightweight foam material is filled into the positioning groove to enhance the connection strength between the top plastic material and the middle aluminum profile. The filled lightweight foam material can provide high strength and thermal insulation effect for aluminum-plastic doors and windows.

[0024] 2. In this application, the weight of the top plastic material is reduced by setting the pressure-resistant groove while enhancing the pressure resistance effect. The set card block can provide further support for the installed glass, making the wind pressure resistance stronger. The set support, plug and slot facilitate the connection between the middle aluminum profile and the bottom plastic material, further enhancing the wind pressure resistance of the middle aluminum profile, and at the same time providing support for the top plastic material.

[0025] 3. In this application, the bottom drainage channel and the top drainage channel are set to ensure thorough drainage and prevent water from accumulating, thus avoiding freezing and cracking in winter due to water retention. The cavity set inside the aluminum profile reduces the structural weight while enhancing the compressive strength of the aluminum profile. Attached Figure Description

[0031] like Figure 1-3 As shown in the figure, this application discloses a wind pressure-resistant aluminum-plastic door and window profile, including a top plastic profile 1, a middle aluminum profile 2, and a bottom plastic profile 3. The bottom of the top plastic profile 1 is provided with the middle aluminum profile 2, and the bottom of the middle aluminum profile 2 is provided with the bottom plastic profile 3. The top plastic profile 1 is provided with a support block 11 inside, and the support block 11 is provided with a plurality of equidistantly distributed pressure-resistant grooves 12 inside. A connecting component 4 is provided between the top plastic profile 1 and the middle aluminum profile 2, and a support component 5 is provided between the middle aluminum profile 2 and the bottom plastic profile 3. Baffles 31 are provided on both sides of the top of the bottom plastic profile 3.

[0032] Both ends of the top plastic profile 1 are fixedly connected with locking blocks 13, which are T-shaped blocks.

[0033] Both sides of the top of the aluminum profile 2 are provided with cavities 21, and the interior of the aluminum profile 2 is provided with positioning grooves 22, which are filled with lightweight foam material 23.

[0034] The connecting assembly 4 includes a support plate 41 fixedly connected to both sides of the bottom end of the top plastic profile 1. A limiting block 42 is fixedly connected to the bottom end of the support plate 41. The limiting block 42 is slidably connected inside the limiting groove 43. The limiting groove 43 is opened inside the reinforcing seat 45. The reinforcing seat 45 is fixedly connected to the bottom end of the positioning groove 22. The support plate 41 is slidably connected to the slot 47. The slot 47 is opened on both sides of the top of the middle aluminum profile 2. The limiting block 42 is a trapezoidal block.

[0035] The connecting component 4 also includes a filler adhesive 44 filled inside the limiting groove 43, and a groove plug 46 is provided on one side of both the limiting groove 43 and the positioning groove 22.

[0036] The support component 5 includes a support member 51 fixedly connected to the top of the bottom plastic profile 3. The inner wall of the support member 51 is fixedly connected to an insert 52. The insert 52 is engaged with the inside of a slot 53. The slot 53 is opened inside both ends of the middle aluminum profile 2.

[0037] The support component 5 also includes sliding grooves 56 formed on both sides of the top of the bottom plastic profile 3, a bottom drainage groove 55 formed at the bottom of the bottom plastic profile 3, and top drainage grooves 57 formed on both sides of the top of the bottom plastic profile 3.

[0039] The working principle of the wind-pressure-resistant aluminum-plastic window and door profile in this embodiment is as follows: During installation, the top plastic profile 1, along with the support plate 41 and the limiting block 42, slides into the limiting groove 43 inside the reinforcing seat 45. When the limiting block 42 at the bottom of the support plate 41 slides into the limiting groove 43, filler 44 is injected into the limiting groove 43. The filler 44 wraps the support plate 41 and the limiting block 42 with the inside of the limiting groove 43, thereby restricting the position of the support plate 41 and the limiting block 42. Then, lightweight foam material 23 is filled into the positioning groove 22, thereby enhancing the connection strength between the top plastic profile 1 and the middle aluminum profile 2. The filled lightweight foam material 23 can provide higher resistance to wind pressure in the aluminum-plastic window and door. The strength and thermal insulation effect are enhanced by reducing the weight of the top plastic profile 1 through the anti-compression groove 12 while increasing the compressive strength. The set block 13 can provide further support for the installed glass, making the wind pressure resistance stronger. The set support 51, insert 52 and slot 53 facilitate the connection between the middle aluminum profile 2 and the bottom plastic profile 3, further enhancing the wind pressure resistance of the middle aluminum profile 2, while providing support for the top plastic profile 1. The set bottom drainage groove 55 and top drainage groove 57 ensure thorough drainage and prevent water retention, avoiding freezing and cracking in winter due to water retention. The cavity 21 set inside the middle aluminum profile 2 reduces the structural weight while enhancing the compressive strength of the middle aluminum profile 2.
