[0024] The utility model provides a universal corner combination connection profile, which includes a connection profile installed between a first window frame and a second window frame on different planes. One end of the first window frame and the second window frame in the width direction are close to each other, and the other end of the first window frame and the second window frame in the width direction are far from each other to form a corner (included angle a). The connection profile includes a first connection module connected to one side of the first window frame close to the second window frame. A second connection module is connected to one side of the second window frame close to the first window frame. A third connection module in a fan shape is arranged between the first connection module and the second connection module. One end of the first connection module and the second connection module close to the included angle a are fixedly connected by hinge, so that the first connection module and the second connection module can rotate. The first connection module and the second connection module are respectively fixedly connected to the third connection module by screws. The utility model solves the problems of multi-angle and non-standard angle corner windows of the existing window frames, and at the same time solves the problems of small corner connection strength, poor sealing performance, and easy air leakage and water leakage.

[0025] Specifically, please refer to Figure 1, A universal corner combination connecting profile according to an embodiment of the present utility model is disposed at the included angle between a first window frame 1 and a second window frame 2. The universal corner combination connecting profile includes a first connecting module 3 connected to the first window frame 1, a second connecting module 4 connected to the second window frame 2, and a third connecting module 5 located between the first connecting module 3 and the second connecting module 4. The connection manner between the first window frame 1 and the first connecting module 3 and the connection manner between the second window frame 2 and the second connecting module 4 can follow the prior art, for example, it can be selected as screw connection, with sealant provided on the outside, etc., which will not be elaborated here. One end of the first connecting module 3 is hinged to one end of the second connecting module 4. The other end of the first connecting module 3 has a first clamping notch 31, and the other end of the second connecting module 4 has a second clamping notch 41. The openings of the first clamping notch 31 and the second clamping notch 41 face each other. The third connecting module 5 is fan-shaped, and both ends of the third connecting module 5 are respectively and fittingly clamped in the first clamping notch 31 and the second clamping notch 41. Thus, the included angle between the first connecting module 3 and the second connecting module 4 can be rotationally adjusted and positioned by the third connecting module 5.

[0026] Preferably, a toothed structure 51 is provided on the outer arc surface of the fan shape of the third connecting module 5. The toothed structure 51 forms a plurality of tooth grooves. Inside the inner sides of the opening ends of the first clamping notch 31 and the second clamping notch 41, there are clamping blocks 52, and the clamping blocks 52 can be fittingly engaged with the tooth grooves of the toothed structure 51. More specifically, the first clamping notch 31 and the second clamping notch 41 are U-shaped, and the side walls are fan-shaped (or arc-shaped) curved. Thus, the fan-shaped third connecting module 5 can be fittingly extended and retracted in the first and second clamping notches to adjust the length of the exposed part of the third connecting module 5 and limit the corresponding angle. The arc-shaped walls on the outer sides of the U-shapes of the first and second clamping notches are used for clamping, and the arc-shaped walls on the inner sides of the U-shapes of the first and second clamping notches are used for auxiliary limiting of the third connecting module 5.

[0027] Further, between the third connection module 5 and the first connection module 3 and the second connection module 4, at the engagement part of the clamping block 52 and the toothed structure 51, they are connected by sealant. The engagement of the aforesaid clamping block 52 and the toothed structure 51 can provide a certain contact strength and sealing performance. Applying sealant at the engagement part can further improve the sealing performance. Also, between the third connection module 5 and the first connection module 3 and the second connection module 4, they are fixedly connected by screws to form an integral corner combination, providing sufficient structural strength. It is preferred to set sealant and screws simultaneously. More specifically, at least three screws are connected between the third connection module 5 and the first connection module 3 and the second connection module 4. Among them, the first screw connects the first clamping groove 31 and one end of the third connection module 5 close to the first connection module 3, the second screw connects the second clamping groove 41 and one end of the third connection module 5 close to the second connection module 4, and the third screw connects the fan-shaped inner side (the arc wall) of the third connection module 5 and the arc wall of the first clamping groove 31 or the second clamping groove 41; thus ensuring the structural stability and reliability with fewer screws. Correspondingly, through holes for installing screws are provided on the first connection module 3, the second connection module 4, and the third connection module 5.

[0028] The first connection module 3 is preferably a heat-insulating composite profile, including a first connection module proximal profile 32, a first connection module rubber strip 33, and a first connection module distal profile 34 connected in sequence. The second connection module 4 is also preferably a heat-insulating composite profile, including a second connection module proximal profile 42, a second connection module rubber strip 43, and a second connection module distal profile 44 connected in sequence. The first connection module proximal profile 32 and the second connection module proximal profile 42 are hinged. The hinging method between the profiles is prior art. For example, one end of the first connection module proximal profile 32 has a C-shaped groove, and one end of the second connection module proximal profile 42 has a cylinder, and the two are fitted together. Also, the first connection module proximal profile 32 and the second connection module proximal profile 42 are preferably in a triangular structure, so as to form a smaller angle and ensure the structural strength. The first clamping groove 31 is located on the first connection module distal profile 34, and the second clamping groove 41 is located on the second connection module distal profile 44. The number, model, and connection structure of the first connection module rubber strip 33 and the second connection module rubber strip 43 can be selected according to actual situations. It is preferred that the proximal profile and the distal profile are connected by two rubber strips. Optionally, a double-broken bridge aluminum profile structure is adopted, that is, it has three profiles and two groups of rubber strips at intervals; all these changes in the profile structure do not exceed the concept of the present utility model.

[0029] Preferably, the structures of the first connection module distal profile 34 and the second connection module distal profile 44 are the same and symmetrically arranged, that is, these two profiles can be universal, and only one type of profile needs to be produced, thereby reducing the number of mold openings and further reducing costs.

[0030] Furthermore, the window frame also adopts heat-insulating composite profiles. That is, the first window frame 1 includes a first window frame proximal profile 11, a first window frame rubber strip 12, and a first window frame distal profile 13 that are connected in sequence; the second window frame 2 includes a second window frame proximal profile 21, a second window frame rubber strip 22, and a second window frame distal profile 23 that are connected in sequence. Preferably, please refer to Figure 2 , the position of the first window frame rubber strip 12 is adjacent to and staggered with the first connection module rubber strip 33 (staggered means not arranged side by side, but similar to a diagonal setting). There is a spacing distance between the first connection module proximal profile 32 and the first window frame distal profile 13 (that is, they do not contact each other), and there is a spacing distance between the first connection module distal profile 34 and the first window frame proximal profile 11 (that is, they do not contact each other). Similarly, the position of the second window frame rubber strip 22 is adjacent to and staggered with the second connection module rubber strip 43. There is a spacing distance between the second connection module proximal profile 42 and the second window frame distal profile 23, and there is a spacing distance between the second connection module distal profile 44 and the second window frame proximal profile 21. This solution can ensure both structural strength and heat-insulating performance at the same time.

[0031] The third connection module 5 is preferably a single profile, which is a hollow tubular structure with a fan-shaped cross-section, saving materials and facilitating production. And, in practice, two or more models of the third connection module 5 with different lengths can be produced for selection, such as Figure 2 , Figure 3 as shown, so that the variable angle range can be expanded by replacing the single profile of the third connection module.

[0032] In summary, the universal corner combination connection profile of the present utility model solves the problems of multi-angle and non-standard angle corner windows of the existing window frames, realizes that the connection profile is applicable to the connection of multi-angle and non-standard angle corner window frames, can meet the requirements of the corner angles of common window frames such as 90°, 120°, and 135°, and can also meet the requirements of non-standard angle corner angles such as 91.5°, 93°, 94.5°, etc. Moreover, it ensures the corner connection strength and sealing performance, avoids problems such as air leakage and water leakage, and at the same time helps to reduce costs and construction difficulties. It should be noted that the orientation descriptions of "far" and "near" in the present utility model are based on the included angle between the first and second window frames and the hinge point of the universal corner combination connection profile for the convenience of description and understanding, and are not a limitation on the structure of the present utility model.
