Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a corner bracket device for connecting UPVC profiles. Background Technology

[0002] In the existing technology, the corners of UPVC profiles are usually connected by welding. However, due to the insufficient strength of the UPVC profiles themselves, the corners have poor load-bearing capacity and are prone to cracking, deformation, and short service life, which cannot meet the current market demand.

[0003] Therefore, to solve the above problems, horizontal and vertical steel linings are respectively installed inside the horizontal and vertical profiles, and external corner brackets are fastened to the corners of the horizontal and vertical profiles. The corner brackets are connected to the horizontal and vertical steel linings through locking devices, thereby transferring the load-bearing force on the corners of the profile components to the pulleys of the built-in steel lining components or corner bracket components. This improves the corner connection strength and load-bearing capacity of the UPVC profiles and greatly extends their service life. Utility Model Content

[0024] like Figure 1-4 As shown, a corner bracket device for connecting UPVC profiles includes a profile assembly 1 and a corner bracket assembly 2. A steel liner assembly 3 is disposed inside the profile assembly 1. The profile assembly 1 includes a horizontal profile 11 and a vertical profile 12 arranged at an angle to each other. The connection between the horizontal profile 11 and the vertical profile 12 forms a corner. The steel liner assembly 3 includes a horizontal steel liner 31 disposed inside the horizontal profile 11 and a vertical steel liner 32 disposed inside the vertical profile 12. The corner bracket assembly 2 is disposed at the corner and is connected to the horizontal steel liner 31 and the vertical steel liner 32 respectively by locking members.

[0025] In this embodiment, by providing horizontal steel linings 31 and vertical steel linings 32 in the horizontal profile 11 and vertical profile 12 respectively, and fastening them to the corners of the horizontal profile 11 and vertical profile 12 by external corner bracket 2, and connecting the corner bracket 2 to the horizontal steel linings 31 and vertical steel linings 32 by locking members, the load-bearing force on the corner of the profile assembly 1 is transferred to the built-in steel lining assembly 3, thereby improving the corner connection strength and load-bearing capacity of the UPVC profile and greatly extending its service life.

[0026] In this embodiment, the above structure can satisfy the reliable connection of small and large profile components 1 at different angles.

[0027] Furthermore, such as Figure 1 As shown, in order to improve the corner strength of the profile assembly 1, the ends where the horizontal steel liner 31 and the vertical steel liner 32 are connected to each other are respectively provided with oblique cut surfaces 10.

[0028] Furthermore, such as Figure 1 , 2As shown in Figures 3 and 4, the corner bracket assembly 2 includes a fixed corner bracket 21 and a connecting corner bracket 22 that cooperate with each other. The fixed corner bracket 21 is connected to the corner and is connected to the vertical steel liner 32 and / or the horizontal steel liner 31 through a locking member. The connecting corner bracket 22 is connected to the fixed corner bracket 21 and the vertical steel liner 32 and / or the horizontal steel liner 31 through a locking member.

[0029] One end of the connecting bracket 22 is provided with a pulley 5 that is slidably connected to the outside.

[0030] In this embodiment, the fixed corner bracket 21 is connected to the built-in steel liner assembly 3 by a locking member, and the connecting corner bracket 22 is connected to the fixed corner bracket 21 and the steel liner assembly 3 by a locking member, thereby transferring the load-bearing force on the corner of the profile assembly 1 to the steel liner assembly 3 or the pulley 5.

[0031] Furthermore, such as Figure 1 , 2 As shown in Figures 3 and 4, in order to improve the connection stability between the fixed angle bracket 21 and the steel liner assembly 3, and to improve the connection stability between the connecting angle bracket 22 and the fixed angle bracket 21 and the steel liner assembly 3, the locking component is a locking screw, and the fixed angle bracket 21 and the connecting angle bracket 22 are respectively provided with multiple threaded holes 20.

[0032] In this embodiment, the screw passes directly through the threaded holes 20 of the fixing bracket 21 and the connecting bracket 22 by rotating the locking screw, and then through the profile assembly 1 and the steel liner assembly 3 for threaded locking connection.

[0033] Furthermore, such as Figure 1 , 2 As shown in Figures 3 and 4, in order to quickly and accurately align the components during connection and improve connection stability, a limiting structure 6 is provided between the fixed corner code 21 and the connecting corner code 22.
