[0032] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A window frame structure strengthening connector includes an L-shaped connecting block 1 and square connecting blocks 2 fixed at both ends of the L-shaped connecting block 1. Counterbores 21 are machined on the square connecting blocks 2. It further includes: an insertion block 22, a locking pin 3, a limiting disc 31, a mounting plate 4, and a return spring 6.

[0033] Furthermore, by Figures 1-3As shown in the figure, in this embodiment, the insertion block 22 is fixed to one end of the square connection block 2. An insertion slot 13 for the insertion block 22 to be embedded is machined on the L-shaped connection block 1. A locking slot 221 is machined on the outer wall of the insertion block 22. A through hole 14 for the locking pin 3 to penetrate is machined on the L-shaped connection block 1. After the locking pin 3 penetrates through the through hole 14, it is embedded in the locking slot 221. And the end face of the embedded end of the locking pin 3 is a slope. The limiting disk 31 is fixed to the end of the locking pin 3 away from the insertion block 22. The mounting plate 4 is supported and fixed to the outer wall of the L-shaped connection block 1 by the fixing rod 5. The return spring 6 is fixed between the limiting disk 31 and the mounting plate 4. After adopting the above scheme, during use, first fix the square connection block 2 at a position near the end inside the window frame profile, and then use the L-shaped connection block 1 for connection. Insert the insertion block 22 into the insertion slot 13. Since the end face of the embedded end of the locking pin 3 is a slope, the slope of the locking pin 3 generates a component force under force, causing the locking pin 3 to move outward. At this time, the return spring 6 contracts until the locking slot 221 moves to the position of the locking pin 3. At this time, the return spring 6 releases elastic force to reset the locking pin 3, and the locking pin 3 is embedded in the locking slot 221 to form a lock, and the combination of the two window frame profiles can be completed. The window frame profiles at other positions are combined in the same way. Finally, use glue to bond and fix the L-shaped connection block 1 in the window frame. The utility model connects two adjacent window frame profiles through the provided L-shaped connection block 1 and two square connection blocks 2, which is convenient, safe, has high connection precision, and ensures the stability of the connection of the window frame profiles.

[0034] Preferably, as Figures 1-3 shown in the figure, in this embodiment, two symmetrically distributed locking pins 3 are provided on both the horizontal part and the vertical part of the L-shaped connection block 1. Two symmetrically distributed locking slots 221 are machined on the outer wall of the insertion block 22. After adopting the above scheme, the stability of the connection between the square connection block 2 and the L-shaped connection block 1 can be greatly improved, thereby improving the stability of the combination of the two window frame profiles.

[0035] Preferably, as Figures 1-3 shown in the figure, in this embodiment, four fixing rods 5 are diagonally distributed. After adopting the above scheme, the stability of the fixation of the mounting plate 4 can be greatly improved.

[0036] Preferably, as Figures 1-4 shown in the figure, in this embodiment, it further includes: positioning convex blocks 131. Two positioning convex blocks 131 are symmetrically fixed to the inner wall of the insertion slot 13. A positioning slot 222 for the positioning convex blocks 131 to be embedded is machined on the outer wall of the insertion block 22. After adopting the above scheme, during use, make the positioning convex blocks 131 embedded in the positioning slots 222, further position the insertion position of the insertion block 22, and at the same time further improve the stability of the insertion of the insertion block 22, and improve the stability of the connection of the window frame profiles.

[0037] Preferably, asFigures 1-3 As shown, in this embodiment, the outer wall of the insertion block 22 abuts against the inner wall of the insertion slot 13. After adopting the above design, during use, the stability of the insertion of the insertion block 22 is further improved, and the insertion block 22 is prevented from shaking, thereby improving the stability of the connection of the window frame profiles.

[0038] Preferably, Figures 1-3 As shown, in this embodiment, the outer wall of the locking pin 3 abuts against the inner wall of the through hole 14. After adopting the above solution, during use, the stability of the locking pin 3 can be effectively improved, and the locking pin 3 is prevented from shaking, thereby improving the stability of the connection of the window frame profiles.

[0039] Preferably, Figure 1 As shown, in this embodiment, a glue storage groove 11 is machined on the outer wall of the L-shaped connecting block 1. After adopting the above solution, during use, the glue will enter the glue storage groove 11, increasing the bonding area, thereby further improving the stability of the L-shaped connecting block 1 bonded in the window frame and improving the stability of the connection of the window frame profiles.

[0040] Preferably, Figure 1 As shown, in this embodiment, it further includes: a corner brace block 12, the corner brace block 12 is fixed between the horizontal part and the vertical part of the L-shaped connecting block 1, and the corner brace block 12 and the L-shaped connecting block 1 are an integrally formed structure by welding. After adopting the above solution, by providing the corner brace block 12, the structural strength of the L-shaped connecting block 1 is further improved.

[0041] The components not described in detail herein are prior art.

[0042] The working principle and usage process of the present utility model: For the connecting piece of the present utility model, during use, first fix the square connecting block 2 at a position near the end inside the window frame profile using bolts, and then use the L-shaped connecting block 1 for connection;

[0043] Insert the insertion block 22 into the insertion slot 13. Since the end face of the embedding end of the locking pin 3 is a slope, a component force is generated when the slope of the locking pin 3 is stressed, causing the locking pin 3 to move outward. At this time, the return spring 6 contracts until the locking groove 221 moves to the position of the locking pin 3. At this time, the return spring 6 releases its elastic force to reset the locking pin 3, and the locking pin 3 is embedded in the locking groove 221 to form a lock, thus completing the combination of two window frame profiles. The window frame profiles at other positions are combined in the same way;

[0044] Finally, use glue to bond and fix the L-shaped connecting block 1 in the window frame, and the glue will enter the glue storage groove 11, increasing the bonding area, thereby further improving the stability of the L-shaped connecting block 1 bonded in the window frame and improving the stability of the connection of the window frame profiles;

[0045] The utility model connects two adjacent window frame profiles through the provided L-shaped connecting block 1 and two square connecting blocks 2, which is convenient, safe, and has high connection precision, and ensures the stability of the connection of the window frame profiles.
