Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite aluminum profile technology, specifically a multifunctional composite aluminum profile. Background Technology
[0002] Composite aluminum profiles are made by mixing and casting aluminum alloy profiles with liquid polymer materials (such as polyurethane) to form an integral structure with two metal layers connected by thermal insulation materials, thereby blocking heat conduction. Because composite aluminum profiles combine aluminum alloys and polymer materials through innovative processes, they have become building materials that are energy-saving, environmentally friendly and durable, and have broad prospects, especially in the fields of doors, windows and curtain walls.
[0003] The published patent document with announcement number CN222595859U discloses a composite aluminum profile. This patent document uses a locking protrusion and a locking strip in partial contact to create a rigid and rough structure at the contact point between the locking protrusion and the locking strip, which greatly improves the interlocking force. This significantly enhances the tensile and shear strength of the finished product. Furthermore, due to the partial contact, the stress point is concentrated, forming a stable compression interlocking connection. However, the aforementioned patent document cannot be spliced into profiles of the required length according to actual needs, and the connection position cannot be adjusted or controlled, making it inflexible in use. Utility Model Content
[0004] The purpose of this utility model is to provide a multifunctional composite aluminum profile that solves the problems mentioned in the background art.
[0005] This application provides a multifunctional composite aluminum profile, including a composite aluminum profile body. A horizontal connecting component is provided between every two horizontally placed composite aluminum profile bodies, and vertical connecting components are provided on both sides between every two vertically placed composite aluminum profile bodies. The horizontal connecting component includes a connector and two threaded shafts. The two threaded shafts are respectively welded to both sides of the connector, and the connector is adapted to the composite aluminum profile body. A threaded hole is opened in the middle of the composite aluminum profile body, and the threaded hole is adapted to the threaded shaft.
[0006] By adopting the above technical solution, the connector is aligned with the two composite aluminum profile bodies, and the composite aluminum profile body is rotated so that the threaded shaft enters the interior of the threaded hole, thus completing the rapid assembly of the two composite aluminum profile bodies and giving the composite aluminum profile a splicing function.
[0007] Optionally, the vertical connecting assembly includes an L-shaped rod and two inner connecting plates. The two inner connecting plates are respectively disposed at the two ends of the L-shaped rod, and the inner connecting plates are integrally cast with the L-shaped rod. A threaded shaft II is threaded through and threadedly connected to the inner connecting plate. A hexagonal groove is provided at one end of the threaded shaft II. Trapezoidal holes matching the vertical connecting assembly are provided at the four outer walls of the composite aluminum profile body.
[0008] By adopting the above technical solution, the vertical connecting component is placed in the corresponding trapezoidal holes of two vertically distributed composite aluminum profile bodies. The end of the hexagonal wrench is inserted into the hexagonal groove and the threaded shaft is rotated to move the threaded shaft and push the inner connecting plate against the trapezoidal hole, thus completing the connection between the two vertically distributed composite aluminum profile bodies. Not only can the connection position be controlled arbitrarily, but the connection is also hidden.
[0009] Optionally, rubber pads are fixedly connected to the four corners at both ends of the composite aluminum profile body.
[0010] By adopting the above technical solution, the friction between the composite aluminum profile body and the connector is reduced, as is the friction between the two composite aluminum profile bodies connected vertically, thus providing a protective function.
[0011] Optionally, two frosted strips are fixedly connected to the edge of the inner connecting plate, and the frosted strips are adapted to the trapezoidal holes.
[0012] By adopting the above technical solution, the friction between the frosted strip and the trapezoidal hole is increased, which can ensure the stability of the inner connecting plate inside the trapezoidal hole.
[0013] Optionally, a hemisphere is fixedly connected to the other end of the threaded shaft.
[0014] By adopting the above technical solution, direct contact between the threaded shaft 2 and the composite aluminum profile body is prevented, thus preventing damage to the composite aluminum profile body.
[0015] Optionally, rounded edges are provided at all four corners of the outer wall of the composite aluminum profile.
[0016] By adopting the above technical solution, the rounded corners of the four outer walls of the composite aluminum profile body reduce the impact force caused by the collision of the composite aluminum profile body.
[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0018] 1. The technical solution of this application can quickly assemble two composite aluminum profile bodies by using the cooperation between the transverse connecting component consisting of the connector and the threaded shaft and the threaded hole, so that the composite aluminum profile has a splicing function and can be spliced into a profile of the required length according to actual needs, making it flexible and convenient to use.
[0019] 2. The technical solution of this application can complete the connection between two vertically distributed composite aluminum profile bodies by using the vertical connection components composed of L-shaped rod, inner connecting plate, threaded shaft, frosted strip, internal hexagonal groove, and hemisphere and trapezoidal hole. Not only can the connection position be controlled arbitrarily, but the connection is also flexible and convenient. Moreover, the connection is hidden and does not occupy space.
[0020] 3. The technical solution of this application reduces friction on the composite aluminum profile body during splicing and connection by setting rubber pads, thus playing a protective role. Attached Figure Description

Detailed Implementation
[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0028] Please see Figure 1-2This utility model provides a multifunctional composite aluminum profile, including a composite aluminum profile body 1. A horizontal connecting component 2 is provided between every two horizontally placed composite aluminum profile bodies 1, and a vertical connecting component 3 is provided on both sides between every two vertically placed composite aluminum profile bodies 1. The horizontal connecting component 2 includes a connector 21 and two threaded shafts 22. The two threaded shafts 22 are respectively welded to both sides of the connector 21, and the connector 21 is adapted to the composite aluminum profile body 1. A threaded hole 11 is opened in the middle of the composite aluminum profile body 1, and the threaded hole 11 is adapted to the threaded shaft 22.
[0029] In this technical solution, by aligning the connector 21 with the two composite aluminum profile bodies 1 and rotating the composite aluminum profile body 1 to allow the threaded shaft 22 to enter the threaded hole 11, the two composite aluminum profile bodies 1 can be quickly assembled, giving the composite aluminum profile a splicing function. It can be spliced into profiles of the required length according to actual needs, making it flexible and convenient to use.
[0030] In some technical solutions, such as Figure 1-3 As shown, the vertical connecting component 3 includes an L-shaped rod 31 and two inner connecting plates 32. The two inner connecting plates 32 are respectively located at the two ends of the L-shaped rod 31, and the inner connecting plates 32 and the L-shaped rod 31 are integrally cast. A threaded shaft 33 is threaded through and threadedly connected to the inner connecting plate 32. A hexagonal groove 35 is provided at one end of the threaded shaft 33. Trapezoidal holes 12 matching the vertical connecting component 3 are provided at the four outer walls of the composite aluminum profile body 1.
[0031] In use, by placing the vertical connecting component 3 into the corresponding trapezoidal holes 12 of the two vertically distributed composite aluminum profile bodies 1, inserting the end of the hexagonal wrench into the hexagonal groove 35 and rotating the threaded shaft 33, the threaded shaft 33 moves and pushes the inner connecting plate 32 against the trapezoidal hole 12, thus completing the connection between the two vertically distributed composite aluminum profile bodies 1. Not only can the connection position be controlled arbitrarily, making the connection flexible and convenient, but the connection point is also hidden and does not take up space.
[0032] In some technical solutions, such as Figure 2 As shown, rubber pads 13 are fixedly connected to the four corners at both ends of the composite aluminum profile body 1.
[0033] In use, the rubber pad 13 reduces friction between the composite aluminum profile body 1 and the connector 21, and also reduces friction when the two composite aluminum profile bodies 1 are vertically connected, thus providing protection.
[0034] In some technical solutions, such as Figure 3-4 As shown, two frosted strips 34 are fixedly connected to the edge of the inner connecting plate 32, and the frosted strips 34 are adapted to the trapezoidal hole 12.
[0035] In use, the friction between the abrasive strip 34 and the trapezoidal hole 12 is increased by the abrasive strip 34, which can ensure the stability of the inner connecting plate 32 inside the trapezoidal hole 12.
[0036] In some technical solutions, such as Figure 4 As shown, a hemisphere 36 is fixedly connected to the other end of the threaded shaft 33.
[0037] During use, the hemispherical body 36 prevents the threaded shaft 33 from directly contacting the composite aluminum profile body 1, thus preventing damage to the composite aluminum profile body 1.
[0038] In some technical solutions, such as Figure 2 As shown, rounded edges 14 are provided at the four corners of the outer wall of the composite aluminum profile body 1.
[0039] When in use, the impact force caused by bumps is reduced by rounding the four corners of the outer wall of the composite aluminum profile body 1.
[0040] Working principle: During use, align the connector 21 with the two composite aluminum profile bodies 1, rotate the composite aluminum profile body 1 so that the threaded shaft 22 enters the threaded hole 11, thus completing the quick assembly of the two composite aluminum profile bodies 1, giving the composite aluminum profile a splicing function. When the two composite aluminum profile bodies 1 are vertically connected, place the vertical connecting component 3 in the corresponding trapezoidal holes 12 of the two vertically distributed composite aluminum profile bodies 1, insert the end of the hexagonal wrench into the hexagonal groove 35 and rotate the threaded shaft 33, so that the threaded shaft 33 moves and drives the hemisphere 36 to contact and abut against the inner wall of the trapezoidal hole 12, and push the frosted strip 34 on the inner connecting plate 32 to abut against the trapezoidal hole 12, thus completing the connection between the two vertically distributed composite aluminum profile bodies 1. Not only can the connection position be controlled arbitrarily, but the connection is also hidden, and the rubber pad 13 can reduce the friction on the composite aluminum profile body during splicing and connection, thus playing a protective role.
[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
