Specific embodiments

[0033] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. The specific structure of the present application is as followsFigures 1-10 As shown in the middle.

[0034] The utility model discloses a kind of corrosion-resistant protective aluminum profiles, including the profile frame 1 with anticorrosive layer on surface, several surface connecting holes 3 are provided on the front side wall surface of the profile frame 1, corner protection piece is installed in the corner part of the front surface of the profile frame 1, middle protection piece is installed in the middle of the front side surface of the profile frame 1 between the two corner protection pieces, the outer surface of the two corner protection pieces and the middle protection piece are flush, the inner end of the two corner protection pieces and the inner end of the middle protection piece are all extended to the inside of the profile frame 1 and are connected by the protection connecting mechanism arranged at its top and bottom, and the two sides and front surface of each protection connecting mechanism are all abutted on the corresponding inner surface part of the profile frame 1.

[0035] Corrosion-resistant protective aluminum profile in the utility model can be used as protective aluminum profile when installing and using, after installation, the corner part and the middle of the whole profile structure can be effectively protected by middle protection piece and corner protection piece, and the protection effect of the whole structure when used outdoors or under harsh conditions can be further enhanced by anticorrosive layer on the surface of profile frame 1. After installing middle protection piece and corner protection piece on aluminum profile, positioning and locking can be quickly completed by protection connecting mechanism at top and bottom, and the risk of middle protection piece and corner protection piece falling off can be reduced in response to swing and vibration in harsh working conditions.

[0036] In any of the above schemes, it is preferred that the surface of the profile frame 1 is sprayed with an electroplated anticorrosive layer. The electroplated anticorrosive layer can form a dense and continuous protective film on the surface of the aluminum profile, isolating the aluminum matrix from the air, moisture, acid, alkali, salt and other corrosive media outside, preventing them from chemically reacting with aluminum, thereby greatly improving the corrosion resistance of the aluminum profile and prolonging its service life. For example, in outdoor building curtain walls, aluminum profiles treated by electroplated anticorrosion can resist the erosion of acid rain, ultraviolet rays and other natural factors.

[0037] In any of the above schemes, it is preferred that the profile frame 1 adopts an aluminum profile frame with a C-shaped cross section. The C-shaped structure is relatively open, and in some space-limited scenarios, compared with closed rectangular or other complex-shaped frames, it can better adapt to special space layout, can be flexibly combined with other components or spaces, is convenient for installing and maintaining various equipment or articles, can effectively utilize space while providing convenient operation space.

[0038] In any of the above solutions, it is preferred that the front surface of the profile frame 1 between the middle protective piece and the corresponding corner protective pieces on both sides thereof is integrally formed with an outwardly protruding reinforcing grid 4, and the outer surface of the outwardly protruding reinforcing grid 4 is flush with the front surface of the middle protective piece. The outwardly protruding reinforcing grid 4 increases the structural complexity and surface area of the aluminum profile, so that when the aluminum profile is subjected to external forces, the forces can be more evenly distributed through the grid structure, avoiding stress concentration in certain specific parts, thereby greatly improving the overall strength of the aluminum profile and enabling it to withstand greater loads.

[0039] In addition, the grid structure is similar to a "ribbed plate" that supports and reinforces the surface of the aluminum profile. When the aluminum profile is subjected to external forces such as bending and twisting, the outwardly protruding reinforcing grid 4 can limit the deformation of the surface of the aluminum profile, so that it can maintain the original shape and dimensional accuracy, ensuring the stability and reliability of the aluminum profile during use. For example, the aluminum profile bracket used in mechanical manufacturing can effectively prevent deformation caused by factors such as vibration during equipment operation.

[0040] In any of the above solutions, it is preferred that the middle protective piece includes a middle protective plate 5 that is butt-jointed to the middle part of the front surface of the profile frame 1, the left and right sides of the middle protective plate 5 are respectively abutted to the corresponding side walls of the outwardly protruding reinforcing grid 4 at their corresponding positions, and the middle protective plate 5 is connected to the protective connection mechanism at its respective corresponding position by means of the middle connecting screw 6 integrally formed on the upper and lower parts of the inner surface thereof and extending into the internal space of the profile frame 1.

[0041] In any of the above solutions, it is preferred that the corner protective piece includes a corner protective plate 7 that is butt-jointed to the edge corner part of the profile frame 1, the two edge corner parts of the corner protective plate 7 are abutted to the corresponding side walls of the profile frame 1 at their corresponding positions, and the corner protective plate 7 is connected to the protective connection mechanism at its respective corresponding position by means of the edge connecting screw 8 integrally formed on the upper and lower parts of the inner surface of the front side edge corner part thereof and extending into the internal space of the profile frame 1.

[0042] The middle protective plate 5 is connected to the corresponding protective connection mechanism by means of the middle connecting screw 6 on the upper and lower parts thereof, which can effectively ensure the stability of the entire connecting structure. At the same time, since the protective connection mechanism cannot rotate in the internal space of the C-shaped aluminum profile frame, it can maintain stable connection with the middle connecting screw 6 and ensure the anti-disconnection effect in a vibrating environment. Similarly, the protective connection mechanism can also simultaneously connect and fix the edge connecting screw 8 of the corner protective piece on both sides, preventing it from loosening and falling off.

[0043] Embodiment 2: Compared with Embodiment 1, the difference lies in that it further comprises the following technical features.

[0044] Preferably, in any of the above solutions, the protection connecting mechanism comprises two opposite and spaced edge anti-loose nuts 9, each of which is threadedly engaged with the end threaded segment of the edge connecting screw rod 8 at its corresponding position, a middle anti-loose nut 10 is arranged between the two edge anti-loose nuts 9, the middle anti-loose nut 10 is threadedly engaged with the outer side wall of the middle connecting screw rod 6 at its corresponding position, a rectangular positioning frame 11 is arranged at the rear side of the middle anti-loose nut 10 and the two edge anti-loose nuts 9, an anti-loose through hole 12 is arranged on the front side wall of each rectangular positioning frame 11 along its left-right direction, a stepped shaft 13 is movably inserted into each anti-loose through hole 12, and the small-diameter segment of the stepped shaft 13 penetrates out of the anti-loose through hole 12 and is coaxially welded and fixedly connected with the rear end face of the middle anti-loose nut 10 or the edge anti-loose nut 9 at its corresponding position.

[0045] The protection connecting mechanism in the utility model mainly relies on the edge anti-loose nut 9 being threadedly engaged with the end threaded segment of the edge connecting screw rod 8 at the corresponding position, and the edge anti-loose nut 9 and the edge connecting screw rod 8 are tightly combined together through the mutual engagement of threads.

[0046] Similarly, the middle anti-loose nut 10 and the middle connecting screw rod 6 are tightly connected through the characteristics of thread connection, and the connection firmness of the middle connecting screw rod 6 is ensured.

[0047] The rectangular positioning frame 11 provides a stable positioning basis for the entire protection connecting mechanism, limits the positions of the nuts and screw rods in space, and prevents unnecessary transverse or longitudinal displacement of the nuts and screw rods during work. Through the constraint of the rectangular positioning frame 11, it is ensured that the nuts and screw rods are always in the correct working position, thereby improving the stability and reliability of the connection. When the nut has a tendency to fall off under the action of external force, the stepped shaft 13 will be limited by the rectangular positioning frame 11, thereby preventing the nut from falling off the screw rod, effectively improving the safety and reliability of the connection, and at the same time, the stepped shaft 13 fitted in the corresponding hole will not affect the flexible rotation during the installation of the nut.

[0048] This buffering action can reduce the direct impact of external force on the connection part of the nut and the screw rod, and reduce the possibility of loosening or falling off of the nut due to excessive instantaneous force.

[0049] In any of the above solutions, preferably, a pressing spring 14 is installed in the space between the middle anti-loose cap 10 and the edge anti-loose cap 9, with the front end of the pressing spring 14 abutting against the front part of the C-shaped cavity of the profile frame 1. The rear end of the pressing spring 14 is fixed to the front surface of the rectangular positioning frame 11 at its corresponding position. When subjected to external forces such as vibration, impact, etc., causing relative looseness between the cap and the screw rod, the front end of the pressing spring 14 abuts against the front part of the C-shaped cavity of the profile frame 1, and the rear end is fixed to the front surface of the rectangular positioning frame 11. The pressing force generated by the spring makes the threads between the cap and the screw rod tightly fit, reducing or even eliminating the thread gap, thereby enhancing the tightness and stability of the connection.

[0050] In any of the above solutions, preferably, side edges perpendicular to the front surface of the profile frame 1 are provided on both sides of the front surface, and a plurality of side reserved holes 2 are arranged on each side edge. The plurality of side reserved holes 2 arranged on the side edges of the front surface of the profile frame 1 provide convenience for the connection of the profile frame 1 with other components. These reserved holes can be used as mounting holes, and bolts, screws, etc. are used to pass through the reserved holes to firmly connect the profile frame 1 with other structural members. For example, when building a large aluminum profile frame structure, different profile frames 1 can be connected to each other through the side reserved holes 2 to form a complete frame system, making the entire structure more stable and firm.

[0051] In summary, the corrosion-resistant protective aluminum profile can be used as a protective aluminum profile during installation and use. After installation, the middle protective member and the corner protective member can effectively strengthen the edge and corner parts and the middle part of the entire profile structure, and the corrosion-resistant layer on the surface of the profile frame 1 can further enhance the protective effect of the entire structure when used outdoors or in harsh conditions. After installing the middle protective member and the corner protective member on the aluminum profile, the protective connection mechanism at the top and the bottom can quickly complete positioning and locking, and can also cope with swinging, vibration, etc. in harsh working conditions, reducing the risk of the middle protective member and the corner protective member falling off. During use, the surface electroplated corrosion-resistant layer can achieve better corrosion resistance; after installation, the middle protective member and the corner protective member on the surface can effectively protect the key parts, ensuring safety when subjected to impact or edge scratching. When connected with the profile frame 1, the protective connection mechanism at the top and the bottom can achieve quick connection and stable positioning; it can also effectively cope with vibration and impact during use, reducing the risk of loosening and falling off; the one-piece middle part with the outwardly protruding reinforcing grid 4 can effectively enhance the strength of the entire aluminum profile structure and the anti-collision effect of the middle part, and also has a certain modeling and decorative effect.

[0052] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application; any alternative improvement or change made by those skilled in the art to the embodiments of the present application falls within the protection scope of the present application.
