Description

Technical Field

[0001] This application belongs to the field of aluminum profile technology, and particularly relates to an aluminum profile for concealed fasteners used in sliding doors. Background Technology

[0002] Aluminum profiles, as a material that combines structural stability and processing flexibility, are widely used in the fields of building decoration and furniture. They are not only commonly used in the construction of window frames, but also extensively used in the structural composition of sliding doors, providing basic support for various opening and closing devices.

[0003] In the assembly of sliding doors, traditional aluminum profile fixing methods often rely on screw heads for connection. These screw heads secure the aluminum profile to other components of the sliding door, ensuring the overall structural stability. This installation method is relatively simple and is commonly used in current sliding door production and assembly. However, after installation, the screw heads are directly exposed on the outer surface of the aluminum profile, compromising its appearance and flatness, significantly impacting the overall visual effect of the sliding door. Furthermore, in actual installation, if the screw head's position is off or the installation depth is improperly controlled, the protruding screw head can easily contact or interfere with the sliding door's track, door frame, and other moving parts, hindering smooth sliding. In severe cases, this can lead to door jamming, component wear, and shortened lifespan of the sliding door. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this application is to provide an aluminum profile for concealed fasteners in sliding doors, which can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a concealed fastener aluminum profile for sliding doors, comprising: The fixing profile includes a first base plate and mating edges located on both sides of the first base plate, the mating edges being used to install a sliding door; The mounting profile is located at the bottom of the fixing profile and includes a second base plate and a mating protrusion at one end of the second base plate. A hidden space for hiding fasteners is formed between the second base plate and the first base plate. Mounting holes are provided on the second substrate for fasteners to pass through; The bottom of the mating edge is provided with a mating groove, which is adapted to the mating protrusion.

[0006] The aforementioned concealed fastener aluminum profile for sliding doors, through the combination of a fixed profile and an installation profile, forms a hidden space between the first and second substrates. When the mounting hole allows the fastener to pass through, the top of the fastener can be completely accommodated within the hidden space, solving the problem of exposed screw heads in traditional sliding door aluminum profile installation. This makes the overall appearance of the sliding door smoother and more complete, enhancing its aesthetics. Simultaneously, the mating grooves on the edges and the mating protrusions on the installation profiles match, providing positioning for the fixed and installation profiles during installation, preventing installation deviations, and thus preventing fasteners or profile structures from interfering with the sliding door's movement, ensuring smooth door sliding. Furthermore, the mating edges of the fixed profile, used for installing the sliding door, provide support. The matching connection between the installation and fixed profiles further enhances the overall structural stability of the aluminum profile, ensuring that the sliding door is less prone to loosening or deformation during long-term use, extending its service life.

[0007] Furthermore, the inner wall of the mating groove is provided with an inwardly protruding limiting protrusion, which is adapted to the mating protrusion and used to limit the mating protrusion.

[0008] The limiting protrusions on the inner wall of the mating groove are adapted to the mating protrusions, effectively limiting the mating protrusions and preventing them from shifting within the mating groove after installation. This further enhances the connection stability between the fixed profile and the installation profile, preventing the sliding door from shaking during use due to loose connections. The limiting function of the limiting protrusions also helps to calibrate the position of the mating protrusions during installation, reducing the difficulty of installation operations, minimizing installation errors, ensuring that the fixed profile and the installation profile always maintain precise alignment, guaranteeing the flatness of the sliding door after installation, and avoiding door movement jamming caused by profile alignment deviations.

[0009] Furthermore: the mating protrusion includes: The positioning protrusion is T-shaped; The sliding latch is arc-shaped, with a T-shaped groove at the bottom that matches the positioning protrusion, and the sides that cooperate with the limiting protrusion. The sealing strip is located on both sides of the positioning protrusion and contacts the side wall of the positioning protrusion and the bottom of the sliding snap-fit ​​component; The sliding latch is made of elastic material, and its two ends are in contact with the top of the limiting protrusion.

[0010] The positioning protrusion is T-shaped and matches the T-shaped groove of the sliding connector. It provides precise sliding guidance for the sliding connector, prevents the sliding connector from shifting during installation or use, ensures the accuracy of the fit between the sliding connector and the limiting protrusion, and further guarantees the stability of the connection between the fixed profile and the installation profile.

[0011] In this application, the sliding snap-fit ​​component is made of elastic material and is arc-shaped. Its two ends contact the top of the limiting protrusion. The elastic material can adapt to minor errors during the installation process and achieve a tight fit with the limiting protrusion through its own deformation. The sealing strip is set on both sides of the positioning protrusion and contacts the side wall of the positioning protrusion and the bottom of the sliding snap-fit ​​component. It can effectively fill the gap between the positioning protrusion and the sliding snap-fit ​​component, extend the service life of the mating protrusion, and maintain the stability of its mating performance.

[0012] Furthermore, the second substrate has an upwardly protruding edge on the side away from the mating protrusion, and the bottom of the first substrate has a edging that contacts the edge, with the sidewall of the edging contacting the sidewall of the edge.

[0013] The second substrate, with its upward protruding edge away from the mating protrusion, contacts the edge sidewall at the bottom of the first substrate, which can improve the stability of the connection between the two. The edge can shield the connection between the edge and the first substrate, further optimizing the appearance of the aluminum profile. In addition, the contact between the edge and the sidewall of the edge can form a protective barrier, preventing external dust and impurities from entering the interior of the aluminum profile through the gap between the two.

[0014] Furthermore, the second substrate is provided with upwardly protruding waterproof protrusions, which are located on both sides of the mounting hole and abut against the bottom of the first substrate.

[0015] The upward-protruding waterproof bumps on the second substrate are located on both sides of the mounting hole and abut against the bottom of the first substrate. They can form a waterproof barrier around the mounting hole, effectively preventing external moisture and liquid from seeping into the hidden space through the gaps in the mounting hole, and preventing fasteners from rusting due to moisture. The waterproof bumps abut against the bottom of the first substrate, which can enhance the structural support between the second substrate and the first substrate, reduce the deformation of the first substrate during the installation and use of the sliding door, and maintain the overall structure of the aluminum profile. In addition, the waterproof bumps can also fill the tiny gaps between the first substrate and the second substrate to a certain extent, reduce dust from entering the hidden space, and further protect the internal components.

[0016] Furthermore, a waterproof rubber strip is provided on the waterproof protrusion, and the waterproof rubber strip contacts the bottom of the first substrate.

[0017] The waterproof rubber strip on the waterproof protrusion contacts the bottom of the first substrate. Utilizing the elastic properties of the rubber strip, it can closely fit the tiny uneven surfaces on the bottom of the first substrate, filling the gap between the waterproof protrusion and the first substrate. Compared with a simple waterproof protrusion structure, it further improves the waterproof sealing effect and effectively prevents moisture and dust from seeping in from the gap.

[0018] Furthermore, a sealing tape is provided between the first substrate and the second substrate for connecting the fixing profile and the mounting profile.

[0019] The sealing tape between the first substrate and the second substrate can tightly connect the two, forming an all-round seal. The adhesiveness of the tape can further strengthen the connection between the two and reduce loosening after installation.

[0020] The beneficial effects of this application are: 1. By combining the fixing profile and the mounting profile, a hidden space is formed between the first base plate and the second base plate. When the mounting hole allows the fastener to pass through, the top of the fastener can be completely accommodated in the hidden space, which solves the problem of exposed screw heads in the installation of traditional sliding door aluminum profiles. 2. The mating grooves on the edge are matched with the mating protrusions on the mounting profile, which can provide positioning for the fixed profile and the mounting profile during installation, avoid installation deviation, and thus prevent fasteners or profile structure from interfering with the movement of the sliding door, ensuring smooth sliding of the door. 3. The upward-protruding waterproof protrusions on the second substrate are located on both sides of the mounting hole and abut against the bottom of the first substrate. They can form a waterproof barrier around the mounting hole, effectively preventing external moisture and liquid from seeping into the hidden space through the gaps in the mounting hole, and preventing fasteners from rusting due to moisture.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The following description, in conjunction with the accompanying drawings, details the aluminum profile for concealed fasteners used in sliding doors provided in this application through specific embodiments and application scenarios.

[0026] Example 1: like Figure 1 and Figure 3 As shown, this application embodiment provides a concealed fastener 500 aluminum profile for sliding doors, comprising: The fixing profile 100 includes a first substrate 110 and mating edges 120 located on both sides of the first substrate 110, the mating edges 120 being used to install a sliding door; Mounting profile 200 is disposed at the bottom of fixing profile 100, including second substrate 210 and mating protrusion 220 located at one end of second substrate 210, and a hidden space 300 for hiding fastener 500 is formed between second substrate 210 and first substrate 110. Mounting hole 400 is provided on the second substrate 210 for fastener 500 to pass through; The bottom of the mating edge 120 is provided with a mating groove 130, which is adapted to the mating protrusion 220.

[0027] In some embodiments of this application, such as Figure 1As shown, using the aforementioned concealed fastener 500 aluminum profile for sliding doors, a concealed space 300 is formed between the first substrate 110 and the second substrate 210 through the combination of the fixing profile 100 and the mounting profile 200. When the mounting hole 400 allows the fastener 500 to pass through, the top of the fastener 500 can be completely accommodated within the concealed space 300, solving the problem of exposed screw heads in traditional sliding door aluminum profile installation. This makes the overall appearance of the sliding door smoother and more complete, improving its aesthetics. Simultaneously, the mating groove 130 of the edge 120 cooperates with the mounting profile... The mating protrusion 220 of the 200 is compatible and can provide positioning for the fixed profile 100 and the mounting profile 200 during installation, avoiding installation deviation and preventing the fasteners 500 or the profile structure from interfering with the movement of the sliding door, thus ensuring smooth sliding of the door. At the same time, the mating edge 120 of the fixed profile 100 is used to install the sliding door and can provide support for the sliding door. The compatible connection between the mounting profile 200 and the fixed profile 100 further enhances the overall structural stability of the aluminum profile, ensuring that the sliding door is not prone to loosening or deformation during long-term use and extending the service life of the sliding door.

[0028] Furthermore, a sealing tape 800 is provided between the first substrate 110 and the second substrate 210 for connecting the fixing profile 100 and the mounting profile 200.

[0029] The sealing tape 800 between the first substrate 110 and the second substrate 210 can tightly connect the two to form an all-round seal. The adhesiveness of the tape can further strengthen the connection between the two and reduce loosening after installation.

[0030] Example 2: This application provides an aluminum profile for concealed fasteners in sliding doors. In addition to the above-mentioned technical features, the aluminum profile for concealed fasteners in sliding doors in this application also includes the following technical features.

[0031] like Figure 1 and Figure 3 As shown, the inner wall of the mating groove 130 is provided with an inwardly protruding limiting protrusion 600, which is adapted to the mating protrusion 220 and used to limit the mating protrusion 220.

[0032] In this embodiment, the limiting protrusion 600 on the inner wall of the mating groove 130 is adapted to the mating protrusion 220, which can effectively limit the mating protrusion 220, preventing the mating protrusion 220 from shifting within the mating groove 130 after installation. This further enhances the connection stability between the fixed profile 100 and the mounting profile 200, and avoids shaking of the sliding door during use due to loose connection between the two. The limiting function of the limiting protrusion 600 can also assist in calibrating the position of the mating protrusion 220 during the installation stage, reducing the difficulty of installation operation, reducing installation errors, ensuring that the fixed profile 100 and the mounting profile 200 always maintain precise alignment, ensuring the flatness of the sliding door after installation, and avoiding door movement jamming caused by profile alignment deviation.

[0033] Furthermore: the mating protrusion 220 includes: The positioning protrusion 610 is T-shaped; The sliding latch 620 is arc-shaped, with a T-shaped groove 621 at the bottom that matches the positioning protrusion 610, and the sides that cooperate with the limiting protrusion 600. A sealing strip 630 is disposed on both sides of the positioning protrusion 610 and contacts the side wall of the positioning protrusion 610 and the bottom of the sliding snap-fit ​​member 620. The sliding latch 620 is made of elastic material, and its two ends are in contact with the top of the limiting protrusion 600.

[0034] The positioning protrusion 610 is T-shaped and matches the T-shaped groove 621 of the sliding connector 620. It can provide precise sliding guidance for the sliding connector 620, prevent the sliding connector 620 from shifting during installation or use, ensure the accuracy of the fit between the sliding connector 620 and the limiting protrusion 600, and further ensure the stability of the connection between the fixed profile 100 and the installation profile 200.

[0035] In this application, the sliding snap-fit ​​620 is made of elastic material and is arc-shaped. Its two ends contact the top of the limiting protrusion 600. The elastic material can adapt to the slight errors in the installation process and achieve a tight fit with the limiting protrusion 600 through its own deformation. The sealing strip 630 is set on both sides of the positioning protrusion 610 and contacts the side wall of the positioning protrusion 610 and the bottom of the sliding snap-fit ​​620. It can effectively fill the gap between the positioning protrusion 610 and the sliding snap-fit ​​620, extend the service life of the mating protrusion 220, and maintain the stability of its mating performance.

[0036] Example 3: This application provides an aluminum profile for concealed fasteners in sliding doors. In addition to the above-mentioned technical features, the aluminum profile for concealed fasteners in sliding doors in this application also includes the following technical features.

[0037] like Figure 1 and Figure 3 As shown, the second substrate 210 has an upwardly protruding edge 700 on the side away from the mating protrusion 220, and the bottom of the first substrate 110 has a edging 710 that contacts the edge 700, with the sidewall of the edging 710 contacting the sidewall of the edge 700.

[0038] In this embodiment, the upward protruding edge 700 of the second substrate 210 away from the mating protrusion 220 contacts the side wall of the edging 710 at the bottom of the first substrate 110, which can improve the stability of the connection between the two. The edging 710 can shield the connection between the edge 700 and the first substrate 110, further optimizing the appearance of the aluminum profile. Moreover, the contact between the edging 710 and the side wall of the edge 700 can form a protective barrier to prevent external dust and impurities from entering the interior of the aluminum profile from the gap between the two.

[0039] Example 4: This application provides an aluminum profile for concealed fasteners in sliding doors. In addition to the above-mentioned technical features, the aluminum profile for concealed fasteners in sliding doors in this application also includes the following technical features.

[0040] like Figure 1 and Figure 3 As shown, the second substrate 210 is provided with an upwardly protruding waterproof protrusion 230, which is located on both sides of the mounting hole 400 and abuts against the bottom of the first substrate 110.

[0041] In this embodiment, the upward-protruding waterproof protrusions 230 on the second substrate 210 are located on both sides of the mounting hole 400 and abut against the bottom of the first substrate 110. They can form a waterproof barrier around the mounting hole 400, effectively preventing external moisture and liquid from seeping into the hidden space 300 through the gaps in the mounting hole 400, and preventing the fasteners 500 from rusting due to moisture. The waterproof protrusions 230 abut against the bottom of the first substrate 110, which can enhance the structural support between the second substrate 210 and the first substrate 110, reduce the deformation of the first substrate 110 during the installation and use of the sliding door, and maintain the overall structure of the aluminum profile. In addition, the waterproof protrusions 230 can also fill the tiny gaps between the first substrate 110 and the second substrate 210 to a certain extent, reduce dust from entering the hidden space 300, and further protect the internal components.

[0042] Furthermore, a waterproof rubber strip 240 is provided on the waterproof protrusion 230, and the waterproof rubber strip 240 contacts the bottom of the first substrate 110.

[0043] The waterproof rubber strip 240 provided on the waterproof protrusion 230 contacts the bottom of the first substrate 110. Utilizing the elastic properties of the rubber strip, it can closely fit the tiny uneven surfaces at the bottom of the first substrate 110, filling the gap between the waterproof protrusion 230 and the first substrate 110. Compared with the simple waterproof protrusion 230 structure, it further improves the waterproof sealing effect and effectively prevents moisture and dust from seeping in from the gap.
