Description

Technical Field

[0001] The utility model relates to the technical field of corner assembly pieces, in particular to a corner assembly piece. Background Art

[0002] The function of the corner piece is to enhance the strength of the corner and make it smooth. With the development of energy-saving window frames, the quality standards for aluminum door and window frames are getting higher and higher. The quality of door and window frames depends on the most important factory processing and assembly process. The corner assembly process is one of the important links, which makes the window frame stronger and more durable.

[0003] In the related art, a solution of an assembled corner piece (Announcement No.: CN219365849U) was discovered through searching. When in use, since the top bending head is formed by bending the tops of two sets of connecting pieces downward, after the two sets of window frame strips are tightly connected, the top bending head is also close to the inner wall of the window frame strip, making the assembled corner piece body more fitting, flush and firm when installed.

[0004] However, after the corner piece is installed, it is necessary to inject glue into the corner piece so that the corner piece can be better fixed inside the window frame. However, during the injection process, the glue will be tightly attached between the window frame and the corner piece, resulting in the corner piece not having a certain buffer space inside the window frame. Therefore, the lack of buffering of the corner piece may increase the friction between the window and the window frame, thereby causing damage or aggravated wear of the window. Long-term friction may cause wear of the window components and the window frame, reducing the service life of the window and the window frame. In view of this, we have introduced a corner piece. Utility Model Content

[0005] The purpose of the utility model is to provide a corner assembly piece to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an angle assembly piece, comprising: a bending plate, a bending portion and a glue injection hole;

[0007] The surface of the bending plate is provided with a stamped convex adjustment group piece, and a buffer groove is provided between the adjustment group piece and the bending plate. The common arrangement of the adjustment group piece and the buffer groove can make the bending plate have a certain elasticity, a buffer space, and will not deform;

[0008] The bending portion is arranged in an arc shape, and the bending portion is arranged at the top end of the outer corner side of the bending plate. After the two sets of window frame strips are tightly connected, the bending portion is also closely attached to the inner wall of the window frame strip, so that the bending plate is more fitted, flush and firm when installed;

[0009] The glue injection hole is circular and is opened on the surface of the bending plate and located at the adjustment assembly piece. The glue injection hole and the bending plate are integrally formed. At the same time, the glue is injected to fix the corner assembly piece after the corner assembly piece is installed.

[0010] Preferably, the bending plate is provided with protrusions at the tails of both wings on one side facing the profile. After the protrusions are allowed to enter the interior of the window frame, they can be used to insert into the interior of the window frame, thereby increasing the firmness between the bending plate and the window frame.

[0011] Preferably, a polished edge is provided on the outer side of the surface of the bending plate. The provision of the polished edge allows the bending plate to be better inserted into the interior of the window frame, thereby making the operation more labor-saving for the operator.

[0012] Preferably, the inner corner of the bending plate is provided with an auxiliary docking semicircular groove for tightly fitting the two wings of the bending plate with the window frame, so that after the window frame is assembled, the inner corner and the outer corner of the window frame are tightly combined to ensure a more perfect window frame assembly.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model contacts the window frame through the adjusting piece and the buffer groove. Since the adjusting piece is protruding on the bending plate, it is convenient to insert the adjusting piece into the interior of the window frame, and then send the glue to the gap between the bending plate, the buffer groove and the window frame. The protruding adjusting piece can limit the flow range of the glue, ensuring that the glue completely fills the gap, improving the quality of gluing, making the connection between the bending plate and the window frame more stable, and there will be no glue overflowing into the inner groove of the window frame, further improving the firmness and integrity of the combination of this group of corner pieces and the window frame strips; and the setting of the buffer groove has a certain elasticity, a buffer space, and will not deform, and then this group of corner pieces improves the safety, beauty and durability of the window frame through reasonable design and efficient sealing.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a corner piece, comprising: a bending plate 1, a surface of the bending plate 1 is provided with a stamped convex adjustment piece 6, and a buffer groove 7 is provided between the adjustment piece 6 and the bending plate 1;

[0020] The bending portion 4 is arranged in an arc shape and is arranged at the top end of the outer corner side of the bending plate 1;

[0021] The glue injection hole 8 is circular and is opened on the surface of the bending plate 1 and is located at the adjustment group piece 6 .

[0022] The bending plate 1 is provided with protrusions 2 at the tail ends of both wings on one side facing the profile. After the protrusions 2 are allowed to enter the interior of the window frame, the protrusions 2 can be used to insert into the interior of the window frame, thereby increasing the firmness between the bending plate 1 and the window frame.

[0023] The outer side of the surface of the bending plate 1 is provided with a polished edge 3. The provision of the polished edge 3 allows the bending plate 1 to be better inserted into the interior of the window frame, thereby making the operation more labor-saving for the operator.

[0024] The inner corner of the bending plate 1 is provided with an auxiliary docking semicircular groove 5 for tightly fitting the two wings of the bending plate 1 with the window frame, so that after the window frame is assembled, the inner corner and the outer corner of the window frame are tightly combined to ensure a more perfect window frame assembly.

[0025] Specifically, when in use, the two folded edges of the bending plate 1 are respectively plugged into the window frame, so that the two window frames are spliced ​​together.
