Description

Technical Field

[0001] This utility model relates to the field of column profile technology, and in particular to a high-performance lightweight aluminum alloy column profile. Background Technology

[0002] In temporary buildings or supporting structures such as outdoor tents, the column profiles are important load-bearing and connecting components. Existing column profiles often have some limitations in design and use. For example, in order to ensure sufficient strength and stability, many profiles have to use thicker materials or complex structures, resulting in excessive weight, which is not conducive to handling and installation and also increases costs. On the other hand, if lightweighting is pursued excessively, its bending and torsional resistance may be sacrificed, and it may not be able to meet the complex outdoor stress requirements, especially under wind load or uneven load, it is easy to deform or even break.

[0003] In addition, the existing column profiles are usually connected by bolts, pins or simple clips. These methods are prone to loosening and are not secure. Even if two methods are combined, the installation process is still too complicated, which is not conducive to installation, disassembly and later maintenance. Utility Model Content

[0004] The purpose of this invention is to significantly reduce its weight while providing excellent bending and torsional resistance, and to facilitate installation, disassembly, and maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-performance lightweight aluminum alloy column profile, including a base plate, wherein an annular flange on the top surface of the base plate divides the top surface of the base plate into an inner surface and an outer surface, at least three L-shaped plates distributed at equal angles are fixed on the inner surface, and a hollow column is placed on the inner surface, the hollow column being located between the annular flange and each L-shaped plate, and each of the three sides of the hollow column is provided with a threaded rod penetrating the hollow column and the corresponding L-shaped plate, and the hollow column is provided with a partition and a locking component for automatically locking when the screw is tightened;

[0006] The locking assembly includes a spring fixed to the partition, and a spring-loaded pin that can extend into a socket on the inner surface to prevent the base plate from detaching from the hollow column.

[0007] As a further description of the above technical solution: the outer surface is provided with at least three positioning holes, which are used to cooperate with the ground mounting base.

[0008] As a further description of the above technical solution: a first connecting plate is fixedly provided on the top of the hollow column, and the first connecting plate is provided with at least two crossbar mounting holes.

[0009] As a further description of the above technical solution: a second connecting plate is fixed to the outer wall of the hollow column and at the bottom position of the first connecting plate, and the second connecting plate is provided with at least two diagonal brace mounting holes.

[0010] As a further description of the above technical solution: the partition divides the inner cavity of the hollow column into three equal-section chambers, and each chamber is provided with a spring, which is used to push the pin to reset when the screw is unscrewed.

[0011] As a further description of the above technical solution: During the screw tightening process, the axial force of the screw causes the pin to enter the insertion hole.

[0012] As a further description of the above technical solution: the annular flange is provided with a locking block, which cooperates with the corresponding slot on the outer wall of the hollow column for quick positioning of the base plate and the hollow column.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By using a triangular base plate and hollow column formed by integral extrusion of aluminum alloy, the self-weight of the component is greatly reduced while ensuring the excellent strength and rigidity of the profile. This improves the portability and ease of use of the product. Furthermore, the design of the triangular cross section and the annular flange gives the column profile excellent bending and torsional resistance, enabling it to withstand complex outdoor loads and meet the stringent requirements of outdoor tents and other structures for column stress.

[0015] 2. Through the partition, spring, pin and socket, mechanical locking can be automatically achieved when the screw is tightened, which further enhances the stable connection between the base plate and the hollow column and significantly improves the safety of the connection. In addition, the partition and spring design inside the hollow column allows the spring to automatically push the pin to reset and disengage from the socket when the screw is loosened, which facilitates the disassembly of the column profile and reduces the difficulty and cost of later maintenance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a high-performance lightweight aluminum alloy column profile, including a triangular base plate 10, the top surface of the base plate 10 is provided with an annular flange 101, the annular flange 101 divides the top surface of the base plate 10 into an inner surface 102 and an outer surface 103.

[0025] No fewer than three L-shaped plates 11 are fixedly installed on the inner surface 102 at equal angles. This equal angle distribution design helps to evenly distribute the force. At the same time, a hollow column 12 is also placed on the inner surface 102. The hollow column 12 is inserted between the annular flange 101 and each L-shaped plate 11 to ensure its positional stability.

[0026] Furthermore, in order to firmly connect the hollow column 12 to the L-shaped plate 11, screws 13 are provided on three sides of the hollow column 12. The screws 13 adopt a threaded connection and penetrate through the wall of the hollow column 12 and the corresponding L-shaped plate 11.

[0027] Furthermore, the hollow column 12 has a partition 14 inside and a locking component 20 inside. The locking component 20 can automatically lock when the screw 13 is tightened, thereby enhancing the reliability of the connection.

[0028] By using a triangular base plate 10 and hollow column 12 formed by integral extrusion of aluminum alloy, the self-weight of the components is greatly reduced while ensuring the excellent strength and rigidity of the profile, thus improving the portability and ease of use of the product. Furthermore, the design of the triangular cross section and the annular flange 101 gives the column profile excellent bending and torsional resistance, enabling it to withstand complex outdoor loads and meet the stringent requirements of outdoor tents and other structures for column stress.

[0029] Furthermore, the locking assembly 20 includes a spring 21, which is fixed to the partition plate 14. A pin 22 is connected to and fixed to the spring 21. The pin 22 can extend into the insertion hole 23 provided on the inner surface 102 of the base plate 10. Through the cooperation between the pin 22 and the insertion hole 23, the base plate 10 and the hollow column 12 can be effectively prevented from accidentally separating, thus ensuring the stability of the overall structure.

[0030] Furthermore, the outer surface 103 of the base plate 10 is provided with at least three positioning holes 104. The main purpose of these positioning holes 104 is to facilitate the connection between the profile and the ground fixing parts or special mounting bases, thereby achieving a stable installation of the entire column on the ground.

[0031] Furthermore, a first connecting plate 15 is fixedly provided on the top of the hollow column 12. The first connecting plate 15 is provided with at least two crossbar mounting holes 151, which are used to connect transverse rods.

[0032] Furthermore, a second connecting plate 16 is fixedly installed on the outer wall of the hollow column 12 and at the bottom of the first connecting plate 15. The second connecting plate 16 is provided with at least two diagonal brace mounting holes 161, which are used to install diagonal support rods, thereby further improving the stability and load-bearing capacity of the overall structure.

[0033] Furthermore, the partition 14 is provided inside the hollow column 12 to divide the inner cavity of the hollow column 12 into three chambers with equal cross-sectional areas. A spring 21 is provided in each such chamber. When the screw 13 is unscrewed, the spring 21 can actively push the pin 22 to reset and disengage it from the socket 23 for easy operation.

[0034] Furthermore, when the screw 13 is tightened, the axial force generated by the screw 13 will act on the pin 22, causing it to enter the socket 23, thereby achieving a secure locking effect.

[0035] The partition 14, spring 21, pin 22, and socket 23 enable automatic mechanical locking when the screw 13 is tightened, further enhancing the stable connection between the base plate 10 and the hollow column 12 and significantly improving the safety of the connection. Furthermore, the design of the partition 14 and spring 21 inside the hollow column 12 allows the spring 21 to automatically push the pin 22 to reset and disengage from the socket 23 when the screw 13 is loosened, facilitating the disassembly of the column profile and reducing the difficulty and cost of later maintenance.

[0036] Furthermore, in order to achieve rapid positioning and initial fixation between the base plate 10 and the hollow column 12, a locking block 17 is provided on the annular flange 101, and a slot 18 corresponding to the locking block 17 is provided on the outer wall of the hollow column 12. During the assembly process, the hollow column 12 can be quickly and accurately positioned on the base plate 10 through the cooperation of the locking block 17 and the slot 18, simplifying the installation steps.

[0037] The locking block 17 on the annular flange 101 engages with the slot 18 on the outer wall of the hollow column 12, enabling it to be positioned during initial installation without the need for additional tools, thus simplifying the installation process. The positioning hole 104 along the outer surface 103 of the base plate 10 can directly engage with the ground fixing component or mounting base, achieving efficient and stable ground installation.
