Technical fields:

[0001] This utility model relates to the field of aluminum profile technology, and in particular to a sealed aluminum profile for doors and windows. Background technology:

[0002] Aluminum alloy doors and windows are widely used in home interior decoration. As users' quality of life improves, the overall quality requirements for aluminum alloy doors and windows also increase. As an important external envelope structure of buildings, aluminum alloy doors and windows have functions such as wind and rain protection, heat insulation, lighting, and ventilation, such as thermally broken aluminum alloy doors and windows. However, in the installation of thermally broken aluminum alloy doors and windows, due to window size limitations or other design factors, the door and window profiles need to be connected by a tenon and mortise structure to form a relatively stable whole. The existing joints between aluminum alloy profiles and tenon and mortise components have poor sealing effects, which leads to indoor and outdoor air flow and affects the heat insulation effect. Therefore, it is necessary to design a new type of aluminum profile structure for doors and windows to solve the above problems. Utility Model Content:

[0003] To solve the above-mentioned technical problems, this utility model provides two connectors of a sealed door and window aluminum profile, which are respectively connected to the locking rails of two profile bodies by a locking plate. The sealing layer on the locking plate can fill the gap between the locking plate and the sealing plate. In addition, the connector is provided with a receiving groove, and a sealing strip is locked in the receiving groove, thereby improving the sealing between the connector and the profile body and preventing indoor and outdoor air flow from affecting the heat insulation effect.

The two connectors are respectively engaged with the retaining rails of the two profile bodies through the retaining plates. The opposite sides of the two connectors are provided with receiving grooves, and sealing strips are engaged in the receiving grooves.

[0005] Preferably, the bending plate is an L-shaped plate, the guide rail is disposed on the inner side of the bending plate, and the top surface length of the guide rail is greater than the bottom surface length.

[0006] Preferably, the card plate is bent outward and has a hook-shaped structure, the sealing layer is disposed on the inner side of the card plate, and the sealing layer abuts against the bent plate when the card plate is engaged with the card rail.

[0007] Preferably, the top of the left and right sides of the connector section is provided with a cover plate, the top of the outer side of the bent plate is provided with a slot, and the cover plate of the connector is inserted into the slot of the bent plate.

[0008] Preferably, the two connectors are connected at the middle of their opposite sides by a heat insulation plate, and multiple retaining strips are provided on the left and right sides of the accommodating groove cross-section.

[0009] Preferably, the sealing strip has a T-shaped structure, and the lower part of the sealing strip is provided with multiple elastic pieces that are inclined outward, and the multiple elastic pieces of the sealing strip are engaged with the multiple retaining strips of the receiving groove.

[0010] The beneficial effects of this utility model are: the sealed aluminum profile for doors and windows works together with the profile body and the connector, so that the two connectors are respectively engaged with the two profile bodies by the clamping plates, and the sealing layer on the clamping plate can fill the gap between the clamping plate and the sealing plate.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0016] like Figure 1-3 As shown, a sealed aluminum profile for doors and windows includes a profile body 1 and a connector 2. Two profile bodies 1 are arranged facing each other, and both the top and bottom of the facing sides of the cross sections of the two profile bodies 1 are provided with inwardly extending bending plates 3, and the bending plates 3 are provided with retaining rails 4. The left and right sides of the cross section of the connector 2 are provided with retaining plates 5, and the retaining plates 5 are provided with sealing layers 6. The two connectors 2 are respectively engaged with the retaining rails 4 of the two profile bodies 1 through the retaining plates 5. The opposite sides of the two connectors 2 are provided with receiving grooves 7, and sealing strips 8 are engaged in the receiving grooves 7.

[0017] The working principle of the sealed aluminum profile for doors and windows described in this utility model is that the profile body 1 and the connector 2 cooperate with each other. The two connectors 2 are respectively engaged with the rails 4 of the two profile bodies 1 by the clamping plates 5. The sealing layer 6 on the clamping plate 5 can fill the gap between the clamping plate 5 and the sealing plate. In addition, the connector 2 is provided with a receiving groove 7, and a sealing strip 8 is engaged in the receiving groove 7, thereby improving the sealing performance between the connector 2 and the profile body 1. Compared with traditional door and window profiles, this sealed aluminum profile for doors and windows provides a sealing layer 6 between the clamping plate 5 and the bending plate 3 of the connector 2 and a sealing strip 8 in the receiving groove 7 of the connector 2, which improves the overall sealing performance and can prevent indoor and outdoor air flow from affecting the heat insulation effect.

[0018] Specifically, the bending plate 3 is an L-shaped plate, the locking rail 4 is disposed on the inner side of the bending plate 3, and the top surface length of the locking rail 4 is greater than the bottom surface length. The locking plate 5 is bent outwards and has a hook-shaped structure. The sealing layer 6 is disposed on the inner side of the locking plate 5, and when the locking plate 5 and the locking rail 4 are engaged, the sealing layer 6 abuts against the bending plate 3. Figures 1 to 3 As shown, the clamping plate 5 is easy to engage with the clamping rail 4 of the bending plate 3. The sealing layer 6 can be a sealing adhesive layer. After the clamping plate 5 and the clamping rail 4 are engaged, a cavity is formed between the clamping plate 5 and the bending plate 3 so that the sealing layer 6 can wrap the sealing layer 6 and fill the gap between the bending plate 3 and the clamping plate 5, thereby improving the sealing performance between the two.

[0019] Furthermore, cover plates 9 are provided on the top of the left and right sides of the cross-section of the connector 2, and slots 10 are provided on the top of the outer side of the bent plate 3. The cover plates 9 of the connector 2 are inserted into the slots 10 of the bent plate 3. The middle of the two connectors 2 facing each other is connected by a heat insulation plate. Multiple retaining strips 11 are provided on the left and right sides of the cross-section of the receiving groove 7. Furthermore, the sealing strip 8 has a T-shaped structure. Multiple elastic pieces 12 are provided on the lower part of the sealing strip 8 at an outward angle. The multiple elastic pieces 12 of the sealing strip 8 are correspondingly engaged with the multiple retaining strips 11 of the receiving groove 7. Figures 1 to 3 As shown, the cover plate 9 of the connector 2 is inserted into the slot 10 of the bending plate 3 to shield the sealing layer 6. The sealing layer 6 improves the sealing performance between the bending plate 3 and the clamping plate 5. The sealing strip 8 can be a sealing rubber strip. The elastic sheet 12 of the sealing rubber strip is pressed into the receiving groove 7 towards the clamping strip 11. The elastic sheet 12 can be made of elastic rubber material. The elastic sheet 12 contacts the clamping strip 11 and undergoes elastic deformation. The elastic sheet 12 bends towards the side wall of the sealing strip 8. After the sealing strip 8 is inserted into the receiving groove 7, the elastic sheet 12 recovers its elastic deformation, thereby making the sealing strip 8 and the receiving groove 7 engage and improving the sealing performance of the connector 2.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
