Description

Technical Field

[0001] This utility model relates to the technical field of thermally insulated aluminum profiles, specifically a thermally insulated aluminum profile with broken bridge. Background Technology

[0002] Thermally broken aluminum profiles, also known as thermally broken aluminum, are a type of building material with excellent performance. They are made by breaking the aluminum alloy in the middle and connecting the broken aluminum alloy with rigid plastic. Since plastic has a significantly lower thermal conductivity than metal, heat does not easily pass through the entire material, thereby improving the material's thermal insulation performance.

[0003] According to a public notice of a thermally broken aluminum profile (Announcement No.: CN217439818U), the above application uses a first mounting base, a second mounting base, a first threaded mounting hole, and a second threaded mounting hole to install the aluminum alloy frame. Even when the thermally broken aluminum profile is compressed, there will be no misalignment between the two aluminum alloy frames that make up the thermally broken aluminum profile, thus affecting the normal use of the thermally broken aluminum profile.

[0004] However, in actual use, the contact area between the aluminum profile and the intermediate plastic connector is limited, making it more prone to loosening due to external forces and thermal expansion and contraction during assembly and use, which in turn leads to safety hazards in the assembly and use of the aluminum profile. In view of this, we propose a thermally insulated aluminum profile. Summary of the Invention

[0005] The purpose of this utility model is to provide a thermally insulated aluminum profile to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermally insulated aluminum profile, comprising an aluminum profile body, an inner cavity formed inside the aluminum profile body, a threaded connecting plate fixedly installed on the outer surface of the end of the aluminum profile body, a mating cavity formed at the end of the aluminum profile body, a serrated groove formed on the inner surface of the mating cavity, a protruding rib fixedly connected to the inner surface of the inner cavity, an inner cylinder fixedly connected to the side wall of the protruding rib, a cross plate fixedly installed on the arc-shaped inner surface of the inner cylinder, an arc-shaped band fixedly connected to the side wall at the center of the cross plate, a snap-fit ​​block fixedly installed on the side wall of the cross plate, and a contact groove formed on the side wall of the snap-fit ​​block near the cross plate.

[0007] Preferably, the number of the docking cavities is set to four, and the four docking cavities are evenly distributed in a circular array around the cross-section of the end of the aluminum profile body, so that when the two sets of aluminum profile bodies are docked, the protrusion of the specially manufactured plastic part located between the two sets of aluminum profile bodies can be inserted into the docking cavity.

[0008] Preferably, the serrated groove is formed on the inner surface of the mating cavity on the side away from the end of the aluminum profile body, and the end of the plastic part that mats with the aluminum profile body is provided with a connecting part adapted to the serrated groove, thereby further increasing the contact area between the plastic part and the aluminum profile body when subjected to force.

[0009] Preferably, the cross plate is located at the center of the inner cylinder and divides the internal cavity of the inner cylinder into four spaces of the same size, in conjunction with four sets of protruding ribs, so that the internal cavity of the aluminum profile body is divided into multiple small spaces.

[0010] Preferably, the length of the cross plate is less than the length of the inner cylinder, so that the plastic part used as the connecting bridge between the two sets of aluminum profile bodies is partially inserted into the inner cavity of the inner cylinder during insertion.

[0011] Preferably, the snap-fit ​​blocks are L-shaped, and there are four sets of snap-fit ​​blocks arranged in a circumferential array on the outer surface of the cross plate. Adjacent sets of snap-fit ​​blocks are staggered, thereby further improving the connection stability between the snap-fit ​​blocks and the plastic parts used for connecting the aluminum profile bodies.

[0012] Compared with the prior art, this utility model provides a thermally insulated aluminum profile with the following advantages:

[0013] 1. This thermally broken aluminum profile features a butt joint cavity and serrated groove, which increases the contact area at the connection point of the aluminum profile body during installation. Simultaneously, the design of the protruding ribs and cross plates enhances the compressive strength and deformation resistance of the plastic parts used for butt joints after the aluminum profile body is assembled, ensuring the stability of the connection between the plastic parts and the aluminum profile body, thereby improving the service life and safety of the aluminum profile body.

[0014] 2. The thermally broken aluminum profile features four sets of circumferentially arrayed and staggered snap-fit ​​blocks and contact grooves, which improves the anti-slip and displacement effect between the plastic parts used to connect the two sets of aluminum profile bodies and the aluminum profile body. This ensures the deformation resistance of the aluminum profile body during assembly and use, thereby guaranteeing the performance of the aluminum profile body. Attached Figure Description

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a thermally insulated aluminum profile, including an aluminum profile body 1, an inner cavity 2 inside the aluminum profile body 1, a threaded connecting plate 3 fixedly installed on the outer surface of the end of the aluminum profile body 1, a mating cavity 4 at the end of the aluminum profile body 1, a serrated groove 5 on the inner surface of the mating cavity 4, a protruding rib 6 fixedly connected to the inner surface of the inner cavity 2, an inner cylinder 7 fixedly connected to the side wall of the protruding rib 6, a cross plate 8 fixedly installed on the arc-shaped inner surface of the inner cylinder 7, an arc-shaped band 9 fixedly connected to the side wall of the center of the cross plate 8, a snap-fit ​​block 10 fixedly installed on the side wall of the cross plate 8, and a contact groove 11 opened on the side wall of the snap-fit ​​block 10 near the cross plate 8.

[0021] In one embodiment of this utility model, four sets of rectangular grooves are provided on the outer wall of the aluminum profile body 1, and the four sets of rectangular grooves are arranged in a circumferential array on the outer wall of the aluminum profile body 1 in the four directions of up, down, left, and right. By setting the rectangular grooves, the internal contact area of ​​the aluminum profile body 1 is increased, thereby improving the docking and installation effect of the aluminum profile body 1 while ensuring the overall strength of the aluminum profile body 1. At the same time, multiple sets of threaded connecting plates 3 are provided, and the threaded connecting plates 3 are respectively set at both ends of the aluminum profile body 1. The threaded connecting plates 3 are provided with through holes for bolt connection, so as to lock and install the aluminum profile body 1 when splicing with other aluminum profile bodies 1.

[0022] In addition, four sets of docking cavities 4 are provided, and the four sets of docking cavities 4 are evenly distributed in a circular array around the cross-section of the end of the aluminum profile body 1. So when two sets of aluminum profile bodies 1 are docked, the protrusion of the specially manufactured plastic part located between the two sets of aluminum profile bodies 1 can be inserted into the docking cavity 4, thereby increasing the contact area between the plastic part and the aluminum profile body 1, and thus increasing the torsional resistance between the aluminum profile body 1 and the plastic part. This avoids the problem of displacement and deformation of the aluminum profile body 1 and the plastic part when subjected to external force after assembly. Furthermore, the serrated groove 5 is formed on the inner surface of the docking cavity 4 away from the end of the aluminum profile body 1. Specifically, the end of the plastic part that docks with the aluminum profile body 1 is provided with a connecting part that matches the serrated groove 5, thereby further increasing the contact area between the plastic part and the aluminum profile body 1 when subjected to force, and ensuring the stability of the plastic part when connected to the aluminum profile body 1.

[0023] In this embodiment of the utility model, four sets of protruding ribs 6 are provided, and the four sets of protruding ribs 6 are evenly distributed in a circumferential array on the arc-shaped outer wall of the inner cylinder 7. The four sets of protruding ribs 6 fix the arc-shaped outer wall of the inner cylinder 7 to the inner surface of the inner cavity 2, thereby ensuring that the inner cylinder 7 can be installed in the center of the inner cavity 2. Furthermore, the separation between the protruding ribs 6 and the inner cylinder 7 divides the space in the inner cavity 2 into several small intervals, so as to facilitate the insertion of sound insulation cotton, thereby improving the sound insulation effect of the aluminum profile body 1 during assembly. At the same time, the cross plate 8 is set in the center of the inner cylinder 7 and divides the internal cavity of the inner cylinder 7 into four spaces of the same size. Together with the four sets of protruding ribs 6, the internal cavity of the aluminum profile body 1 is divided into multiple small spaces, thereby improving the heat insulation and sound insulation effect of the aluminum profile body 1 in conjunction with the filled sound insulation cotton.

[0024] Furthermore, four sets of arc-shaped bands 9 are provided, and the arc-shaped bands 9 are arranged around the center of the cross plate 8 to strengthen the connection between the plates of the cross plate 8, and to make the outer surface of the connection between the plates have an outward arc shape. The length of the cross plate 8 is less than the length of the inner cylinder 7, so that the plastic part used as the connecting bridge between the two sets of aluminum profile bodies 1 is partially inserted into the inner cavity of the inner cylinder 7 during insertion. The end of the plastic part has a cross-shaped notch that matches the end of the cross plate 8, thus maintaining a sufficiently large contact area between the plastic part and the cross plate 8, thereby ensuring the connection stability of the plastic part. Specifically, the plastic part… The end is provided with a connection end adapted to the snap-fit ​​block 10. Specifically, the snap-fit ​​block 10 is L-shaped and has multiple sets of contact grooves 11 arranged in a linear array on the lower surface of the snap-fit ​​block 10. There are four sets of snap-fit ​​blocks 10 arranged in a circumferential array on the outer surface of the cross plate 8, and adjacent sets of snap-fit ​​blocks 10 are staggered. This further improves the connection stability between the snap-fit ​​block 10 and the plastic parts used for the connection between the aluminum profile body 1 and the aluminum profile body 1, ensuring the deformation resistance of the aluminum profile body 1 during assembly and use, and thus ensuring the performance of the aluminum profile body 1.

[0025] In this utility model, during use, the aluminum profile body 1 is connected to another set of aluminum profile bodies 1, and the plastic part that serves as a bridge between the two is first aligned with the end of one set of aluminum profile bodies 1 and inserted, so that the protrusion of the plastic part is inserted into the docking cavity 4 and finally abuts against the serrated groove 5. At the same time, the cross-shaped notch at the end of the plastic part is aligned with the cross plate 8, and finally, after insertion, the connecting end of the plastic part is inserted into the staggered L-shaped snap-fit ​​blocks 10, thereby strengthening and fixing the plastic part inside the aluminum profile body 1. Then, the other set of aluminum profile bodies 1 is connected to the other end of the plastic part in the same way. After that, the threaded connecting plates 3 of the two sets of aluminum profile bodies 1 are threaded and locked together with bolts to realize the docking and installation of the aluminum profile bodies 1. Finally, after the assembly is completed, sound insulation cotton is stuffed into the space in the inner cavity 2 to ensure the heat insulation effect of the aluminum profile body 1 during use.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
