[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 and Figure 2 As shown, this embodiment provides a corner bracket and aluminum profile assembly for quick assembly and disassembly of aluminum profiles, including a corner bracket body 1 and an aluminum profile body 2.

[0023] The corner bracket body 1 is injection molded from engineering plastic, possessing good toughness and strength. The corner bracket body 1 includes two integrally molded connecting parts 10, which are symmetrically arranged to form a cylindrical structure. The cross-section of each connecting part 10 is rectangular, and each connecting part 10 has a snap-fit ​​protrusion 11 on both surfaces. A movable slot 12 is provided around each snap-fit ​​protrusion 11, allowing it to have a certain elastic deformation capacity under stress, facilitating insertion and removal. The surface of the snap-fit ​​protrusion 11 is provided with anti-slip grooves 13 and anti-slip textures to facilitate worker operation and increase friction during operation. A positioning post 14 is provided between the two connecting parts 10 to improve the stability of the aluminum profile body 2 during installation.

[0024] The four surfaces of the connecting part 10 are provided with reinforcing ribs 15, which extend to the ends of the connecting part 10, effectively enhancing the bending resistance of the connecting part 10 and allowing it to be pressed against the inner wall of the aluminum profile body 2, thus increasing the connection effect. The edges of the reinforcing ribs 15 are provided with chamfered portions 16, and the ends of the connecting part 10 are machined with guide bevels. The chamfered portions 16 and the guide bevels are flush, together forming a smooth guide structure, which facilitates the insertion of the corner bracket body 1 into the aluminum profile body 2.

[0025] The aluminum profile body 2 is an extruded aluminum material, and its end has a rectangular cavity that matches the shape of the connecting part 10. On the side wall of the aluminum profile body 2, there is a snap-fit ​​groove 21 corresponding to the position of the snap-fit ​​protrusion 11. On the inner side of the end face of the aluminum profile body 2, there is a positioning groove 22 that matches the positioning post 14 on the corner bracket body 1. One side edge of the aluminum profile body 2 extends outward to form a poster mounting plate 23, which has a poster mounting groove 24 for clamping the edge of the poster. To increase the clamping force and prevent the poster from slipping out, the inner wall of the poster mounting groove 24 is designed to be corrugated.

[0026] During assembly, the two connecting parts 10 of the corner bracket body 1 are aligned and inserted into the end cavities of the two aluminum profile bodies 2 to be connected. During insertion, the guide bevel and chamfer 16 guide the corner bracket smoothly into place, and the locking protrusion 11 is squeezed by the inner wall of the cavity, generating elastic deformation through the movable seam 12. When the corner bracket is inserted into place, the locking protrusion 11 springs into the locking groove 21 on the side wall of the aluminum profile, making a "click" sound, completing the locking. At the same time, the positioning post 14 is also inserted into the positioning groove 22 at the end of the aluminum profile, achieving precise positioning and preventing the profile from rotating. During disassembly, simply pull the aluminum profile outward to disengage the locking protrusion 11 from the locking groove 21.

[0027] Example 2

[0028] This embodiment further enhances the design for structural stability based on Embodiment 1.

[0029] like Figure 3As shown, for larger poster stands, a reinforcing rod 3 is added in this embodiment to enhance the overall frame rigidity and prevent swaying in the middle. The reinforcing rod 3 is a metal rod or a high-strength composite rod, and a connecting plate 31 is fixed to its end. The connecting plate 31 has mounting holes 32. During assembly, the connecting plates 31 at both ends of the reinforcing rod 3 are respectively placed to connect with the aluminum profile body 2 connected to the upper and lower ends of the corner bracket body 1. Expansion screws 34 and expansion tubes 33 are used to pass through the mounting holes 32 and lock them to the side wall of the aluminum profile body 2. This detachable reinforcing structure ensures the stability of the frame without affecting the overall quick assembly and disassembly characteristics.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
