[0002] Corner bracket connectors for doors and windows refer to the connectors between aluminum alloy door panels and outer frames. They are generally made of materials such as aluminum, glue, and zinc. Corner bracket connectors mainly play a role in the installation of the main door frame and the assembly of door frame components during the assembly of doors and windows.
[0003] For example, in the corner bracket connector for door and window frames disclosed in CN215213125U, a connecting rod is connected between the bottom plate and the top plate, and a rotating bolt is connected to the outer wall of the connecting rod. The upper part of the connecting rod has a positive thread, and the lower part has a negative thread opposite to the positive thread, so that when the connecting rod rotates, it can drive the bottom plate and the top plate to move in two opposite directions, thereby realizing the clamping and fixing function of the connector and the outer frame of the door and window.
[0004] The aforementioned corner bracket connectors are connected by connecting rods, which are threaded to the base plate. The threaded holes on the connecting rods do not penetrate the base plate, so the moving distance of the connectors is less than the thickness of the connectors. The maximum change in distance between the two connectors is the sum of the thicknesses of the two connectors. Therefore, the corner bracket connectors are applicable to a limited range of door and window frames. Utility Model Content

[0007] Preferably, the telescopic frame is equipped with connecting rods at the top and bottom, and a sleeve is installed between the two connecting rods. The sleeve has a through hole, and a pin is inserted into the through hole.
[0008] Preferably, a corner groove is provided at the corner of the connecting workpiece, a friction layer is provided on the connecting workpiece, and a guide groove is provided in the middle of the friction layer.
[0009] Preferably, the length of the friction layer is less than the width of the connected workpiece, and a sponge is installed on the side of the friction layer away from the corner of the connected workpiece.
[0010] Preferably, a fixing hole is provided on the side of the connecting workpiece, and a fixing bolt is provided inside the fixing hole. The fixing bolt has a hollow structure, and the interior of the fixing bolt communicates with the outside through an injection hole. An adhesive outlet hole is provided inside the fixing bolt.
[0011] Preferably, the dispensing hole and the injection hole are connected, and connecting grooves are provided at both ends of the workpiece. The connecting grooves penetrate the interior of the fixing hole and are aligned with the dispensing hole.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model is equipped with a telescopic frame and a sleeve. The telescopic frame changes the distance between two connected workpieces, and the sleeve fixes the telescopic frame, so that the length of the telescopic frame is fixed. The change in the distance between the connected workpieces is the telescopic length of the telescopic frame. It can be adjusted according to the door and window frame, so as to expand the application range of the corner bracket connector.
[0014] 2. This utility model incorporates a sponge, whose elasticity facilitates pushing the door and window frame on the other side, reducing friction between the door and window frame and the connecting workpiece. The corner glue fills the corner glue groove and the guide groove, so that the connecting parts are fixed and their stability is enhanced by the corner glue, thereby strengthening their durability and service life.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 The present invention provides the following technical solution:
[0023] A corner bracket connector for door and window frames includes a connecting workpiece 1, a telescopic frame 2 installed on the connecting workpiece 1, the telescopic frame 2 connecting two connecting workpieces 1, a connecting rod 3 installed at the top and bottom of the telescopic frame 2, a sleeve 10 installed between the upper and lower connecting rods 3, a through hole 15 installed on the sleeve 10, and a pin 11 inserted inside the through hole 15.
[0024] Insert the end of the connecting workpiece 1 away from the telescopic frame 2 into the hollow part of the door and window outer frame. Then pull the connecting workpiece 1 up and down. The movement of the connecting workpiece 1 causes the connecting rod 3 to move synchronously. The movement of the connecting rod 3 causes the sleeve 10 to extend until it can no longer be pulled. Then stop pulling and insert the pin 11 into the through hole 15. The pin 11 fixes the sleeve 10, thereby fixing the connecting workpiece 1 and achieving the clamping and fixing function of the door and window outer frame.
[0025] An angle glue groove 5 is provided at the corner of the connecting workpiece 1. A friction layer 4 is provided on the connecting workpiece 1. A guide groove 9 is provided in the middle of the friction layer 4. A fixing hole 13 is provided on the side of the connecting workpiece 1. A fixing bolt 6 is provided inside the fixing hole 13. The fixing bolt 6 has a hollow structure. The interior of the fixing bolt 6 is connected to the outside through the glue injection hole 12. A glue outlet hole 7 is provided inside the fixing bolt 6. The glue outlet hole 7 is connected to the glue injection hole 12. A connecting groove 14 is provided at both ends of the connecting workpiece 1. The connecting groove 14 penetrates the interior of the fixing hole 13 and is aligned with the glue outlet hole 7.
[0026] Rotate the fixing bolt 6 from the outside of the door / window into the fixing hole 13 inside the connecting workpiece 1 for secondary fixation. When the fixing bolt 6 is completely rotated into the fixing hole 13, the position of the glue outlet 7 matches the connecting groove 14. Next, after the connecting parts and the outer frame of the door / window are completely fixed, inject corner glue into the fixing bolt 6 through the glue injection hole 12. The corner glue inside the fixing bolt 6 then enters the guide groove 9 through the connecting groove 14. The corner glue in the guide groove 9 then enters the corner glue groove 5 along the guide groove 9. This achieves the effect of filling the connecting workpiece 1 with corner glue, making the connection structure more stable and sealed. Finally, let the outer frame of the door / window stand still to allow the corner glue to fully expand and fill the interior of the connecting workpiece 1.
[0027] The length of the friction layer 4 is less than the width of the connecting workpiece 1, and a sponge 8 is installed on the side of the friction layer 4 away from the corner of the connecting workpiece 1.
[0028] After the door and window frame on one side of the workpiece 1 is installed, the door and window frame is then put on the other side of the workpiece 1. Due to the setting of the sponge 8, the sponge 8 has a certain degree of softness, so it is easy to put on the door and window frame quickly.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
