[0032] Please refer to Figure 2 The door and window frame outer profile splicing and correction structure provided in the embodiments of the present application includes a correction sheet 3 and a slot 2 located on the inner side of the frame outer profile 1 for inserting and mounting the correction sheet 3. On the inner side of each of the two frame outer profiles 1 to be spliced, there are two slots 2 on each frame outer profile 1, and the two slots 2 are both surrounded by an L-shaped structure protruding from the inner side of the frame outer profile 1, and are respectively used for inserting the two side edges of the correction sheet 3; the corresponding slots 2 on the two frame outer profiles 1 to be spliced are vertically connected with the joint as the boundary.

[0033] Please refer to Figure 3 and Figure 2 , the correction piece 3 is integrally formed by two vertical inserts 4 and two vertical side plates 5. The two inserts 4 are respectively inserted into the corresponding slots 2, and the two side plates 5 are integrally connected to the outer edges of the corresponding inserts 4, and the side faces are perpendicular to the frame outer profile 1, and the two side plates 5 are also integrally connected at the joint.

[0034] Please refer to Figure 3 and Figure 2 , the side plate 5 is provided with a first platform surface 61 and a first inclined surface 62 on the side face away from the frame outer profile 1. The first platform surface 61 is located at one end of the side plate 5 close to the joint, and the first platform surface 61 is in interference fit with the inner side wall of the slot 2, and the interference distance is 0.1mm. The length of the first platform surface 61 along the length direction of the side plate 5 is at least 5mm, and at most 1 / 10 of the length of the side plate 5; the length of the first platform surface 61 in this embodiment is preferably 5mm. The first platform surfaces 61 on the two side plates 5 are flush.

[0035] Please refer to Figure 3 and Figure 2 , the first inclined surface 62 is located between the first platform surface 61 and the end of the side plate 5 away from the joint, the top of the first inclined surface 62 is connected with the first platform surface 61, and the bottom is located at the end of the side plate 5 away from the joint, and there is a gap between the first inclined surface 62 and the inner side wall of the slot 2; on the one hand, the gap can make the side plate 5 smoothly and unobstructedly inserted into the slot 2, and on the other hand, it also reduces the contact area of the interference fit between the side plate 5 and the inner side wall of the slot 2, and reduces the probability that the unevenness of the inner side wall of the slot 2 affects the correction effect of the correction piece 3. The end of the insert 4 and the side plate 5 away from the joint is provided with a round corner 13, which has a guiding effect on the insertion of the correction piece 3 into the slot 2.

[0036] Please refer to Figure 3 and Figure 2 , the two flush first platform surfaces 61 on the two side plates 5 are in interference fit with the inner side wall of the slot 2, which can top the inner side faces of the two frame outer profiles 1 to the same distance from the inner side wall of the slot 2, so that the outer side faces of the two frame outer profiles 1 are flush. The inner side wall of the slot 2 is inevitably locally uneven, compared with the prior art that the entire side face of the correction piece 3 is in interference fit with the inner side wall of the slot 2, the first platform surface 61 with a smaller area on the side plate 5 is in interference fit with the inner side wall of the slot 2, which reduces the probability that the unevenness of the inner side wall of the slot 2 affects the correction effect of the correction piece 3; and the contact area of the first platform surface 61 and the inner side wall of the slot 2 is located at the mouth of the slot 2, even if the mouth of the slot 2 has unevenness, it is also convenient to polish.

[0037] Please refer to Figure 3 and Figure 2The outer side of the side plate 5 is provided with a second platform surface 71 and a second inclined surface 72. The second platform surface 71 is located at one end of the side plate 5 close to the joint, and the second platform surface 71 is in interference fit with the groove bottom of the slot 2, and the interference distance is 0.1 mm. The length of the second platform surface 71 along the length direction of the side plate 5 is at least 5 mm, and at most 1 / 10 of the length of the side plate 5; the length of the second platform surface 71 is preferably 5 mm in this embodiment. The second inclined surface 72 is located between the second platform surface 71 and the end of the side plate 5 away from the joint, the top of the second inclined surface 72 is connected with the second platform surface 71, and the bottom of the second inclined surface 72 is located at the end of the side plate 5 away from the joint. The second inclined surface 72 has a gap with the groove bottom of the slot 2, and the gap has the same effect as the gap between the first inclined surface 62 and the inner side wall of the slot 2.

[0038] In this embodiment, the interference fit between the second platform surface 71 and the groove bottom of the slot 2 can push the inner side wall of the slot 2 in the width direction of the frame outer profile 1, so that the anti-deformation ability of the frame outer profile 1 in the width direction is improved, and the frame outer profile 1 is not easy to protrude outward or recess inward, thereby providing a prerequisite for the outer surfaces on both sides of the joint of the frame outer profile 1 to be flush.

[0039] Please refer to Figure 2 and Figure 3 The central part of the groove bottom of the slot 2 in the width direction protrudes upward to form a protruding strip 9, and the protruding strip 9 extends along the length direction of the slot 2. The top surface of the protruding strip 9 replaces the original groove bottom of the slot 2, and the top surface of the protruding strip 9 serves as a new groove bottom and is in interference fit with the second platform surface 71, and the interference distance is also 0.1 mm; the second inclined surface 72 has a gap with the top surface of the protruding strip 9. The protruding strip 9 is equivalent to a reinforcing rib, which strengthens the groove bottom of the slot 2 and makes the groove bottom of the slot 2 not easy to deform in concave-convex manner; under the premise that the groove bottom is not easy to deform in concave-convex manner, the top surface of the protruding strip 9 formed on the groove bottom will not be deformed. The contact surface between the top surface of the protruding strip 9 and the second platform surface 71 is smaller than the contact surface between the groove bottom of the slot 2 and the second platform surface 71, so the probability that the unevenness at the contact surface affects the correction sheet 3 is also reduced.

[0040] Please refer to Figure 2 One side of the insertion piece 4 facing the frame outer profile 1 is a flat surface and is attached to the inner side surface of the frame outer profile 1; the other side of the insertion piece 4 away from the frame outer profile 1 is provided with a third platform surface 81 and a third inclined surface 82, and the third platform surfaces 81 on the two insertion pieces 4 are flush. The third platform surface 81 is located at one end of the insertion piece 4 close to the joint, and the third platform surface 81 is in interference fit with the inner side wall of the slot 2, and the interference distance is also 0.1 mm. The third inclined surface 82 is located between the third platform surface 81 and the end of the insertion piece 4 away from the joint, the top of the third inclined surface 82 is connected with the third platform surface 81, and the bottom of the third inclined surface 82 is located at the end of the insertion piece 4 away from the joint. The third inclined surface 82 has a gap with the inner side wall of the slot 2, and the gap has the same effect as the gap between the first inclined surface 62 and the inner side wall of the slot 2.

[0041] The two third platform surfaces 81 on the two inserts 4 are in flush interference fit with the inner side walls of the slots 2, which can top the inner side walls at the opening of the slots 2 of the two frame outer profiles 1 to flush, thereby indirectly making the outer surfaces of the two frame outer profiles 1 flush at the joint.

[0042] Please refer to Figure 3 and Figure 2 After the two vertical frame outer profiles 1 are spliced, a male corner is generated at the joint, and the male corner points to the inner corner where the two inserts 4 meet. The two inserts 4 are provided with a clearance hole 12 at the inner corner, which is used to avoid the male corner.

[0043] Please refer to Figure 2 and Figure 4 After the correction piece 3 is clamped into the slots 2 of the two frame outer profiles 1 and the outer surfaces of the joint are flush, glue needs to be injected to firmly bond the correction piece 3 to the frame outer profiles 1. The correction piece 3 is provided with a glue injection groove 10 on the side surface facing the frame outer profiles 1, and the glue injection groove 10 is arranged in the direction of the joint. The third platform surface 81 is provided with a glue injection hole 11 communicating with the glue injection groove 10. A glue injection needle tube injects glue into the glue injection groove 10 from the glue injection hole 11, and the glue enters the slots 2 from the upper and lower ends of the glue injection groove 10, respectively, to fill the gap between the surface of the correction piece 3 and the inner wall of the slot 2. After the glue solidifies, the correction piece 3 is stably fixed in the slot 2.

[0044] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
