[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Example 1

[0030] like Figures 1 to 5As shown, a corner connection structure for wooden doors and windows includes horizontal profiles 1 and vertical profiles 2 perpendicularly distributed to each other. The ends of the horizontal profiles are provided with beveled half-tenons 101, which are integral with the horizontal profiles to ensure structural strength. The beveled half-tenon 101 is an isosceles right-angled triangular plate-like structure formed by cutting off the front of the beveled tenon at the end of the horizontal profile. The ends of the vertical profiles are provided with mortises 201 that mate with the beveled half-tenons. The thicknesses of the horizontal and vertical profiles are... The thickness of the beveled half-tenon is equal to that of the horizontal profile. The beveled half-tenon and the mortise are bonded together with tenon adhesive. A connecting nail 4 is used to connect the beveled half-tenon to the beveled surface of the vertical profile to improve the stability and strength of the connection structure. In this embodiment, the connecting nail is a wave nail. The mortise is opened on the back of the vertical profile. After the horizontal profile and the vertical profile are spliced ​​together, they form the corner of the door and window. The beveled surface of the beveled half-tenon and the splice of the vertical profile form a 45° bevel angle of traditional doors and windows. Since the mortise is opened on the back of the vertical profile, the splice of the front of the vertical profile and the horizontal profile is a right angle structure, which can effectively hide the beveled part. Even if cracks occur at the beveled splice, they cannot be seen from the front (outer side) of the door and window corner, thus ensuring the aesthetics of the outer side of the door and window corner.

[0031] Combination Figure 1 and Figure 2 As shown, the side of the horizontal profile near the beveled half tenon is a sloping surface. The joint between the sloping surface 102 and the vertical profile forms an expansion joint 3. The expansion joint not only provides a certain deformation space for the wooden profile, effectively improving the cracking caused by changes in external temperature or humidity, but also enhances the aesthetics of the corner.

[0032] Example 2

[0033] like Figure 6 As shown, this embodiment of a wooden door and window corner connection structure adds an L-shaped positioning groove and an L-shaped positioning element to the structure of embodiment 1. A horizontal through groove 501 is provided on the back of the horizontal profile, and a vertical through groove 502 is provided on the back of the vertical profile. The horizontal and vertical through grooves are perpendicular to each other and connected to form an L-shaped positioning groove 5. An L-shaped positioning element 6 is provided within the L-shaped positioning groove. The L-shaped positioning element enhances the structural stability between the horizontal and vertical profiles and reduces the occurrence of cracking. In this embodiment, the L-shaped positioning element is made of aluminum alloy, which is lightweight and high-strength.

[0034] Example 3

[0035] like Figure 7As shown, this embodiment of a wooden door and window corner connection structure adds L-shaped positioning grooves and L-shaped positioning elements to the structure of embodiment 1, with two or more L-shaped positioning grooves. The L-shaped positioning elements improve the stability and connection strength of the wooden door and window corner connection structure. When this wooden door and window corner connection structure is applied to aluminum-wood or other composite doors and windows, the excess L-shaped positioning grooves can be used to accommodate sealing strips or snap fasteners for other composite profiles.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
