Description

Technical Field

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

[0002] During the assembly process of casement windows, when doors, windows or sashes are connected by angle brackets, the interface becomes a weak point. The role of the angle piece is to enhance the strength of the connection point, make the interface smooth, and make the doors and windows stronger and more durable.

[0003] In the related technology, a solution of a top-thread glue-injected corner piece (Announcement No. CN210918750U) was found through a search. The glue liquid is injected through the injection port, sent into the guide groove through the guide channel and then distributed in the entire injection area, which makes the injection efficiency higher. After the injection glue is completely cured, it is more beautiful, strong, waterproof, heat-insulating and sound-proof.

[0004] However, the corner piece used in the above scheme is a commonly used one in the industry. The positioning concave strips are used to create a gap between the corner piece and the window frame, which makes it easier to inject glue into the gap. However, the length of the window frame is much larger than the corner piece. When injecting glue, after the glue flows into the gap, the glue will flow into the window frame, making it difficult for the glue to completely fill the gap between the corner piece and the window frame. Injection of glue can only be based on experience, and it is difficult to judge whether the injected glue is sufficient, and over-injection of glue is very likely to occur. Utility Model Content

[0005] The utility model aims to provide a door and window corner piece to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a door and window corner piece, comprising a bending plate, a glue injection hole is provided at the corner of the bending plate, a bending portion is provided at the corner of the bending plate, a receiving groove is provided on the surface of the bending plate, and the receiving groove is surrounded by the side of the glue injection hole;

[0007] A balancing block, which is arranged in an arc shape and is fixedly connected to the surface of the bent portion. The balancing block cooperates with the sealing strip to ensure that the bent plate will not tilt in the window frame;

[0008] Two sealing strips are provided and fixedly connected to the lower edge of the surface of the bending plate. The sealing strip cooperates with the bending plate and the window frame to limit the free flow of the glue, so that the glue completely covers the bending plate, thereby improving the strength of the connection between the bending plate and the window frame.

[0009] Furthermore, a groove is provided on the surface of the bending plate, and a convex block is provided on the other side of the bending plate, and the position of the convex block corresponds to the position of the groove, and the surface of the convex block window frame supports the bending plate to facilitate glue injection.

[0010] Furthermore, an overflow port is provided on the surface of the sealing strip, which can discharge air more quickly and facilitate smooth injection of glue.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The lower part of the bending plate is sealed by a sealing strip. When the bending plate is installed on the window frame, the sealing strip can form a boundary for the gap between the bending plate and the window frame to prevent the glue from flowing freely into the window frame. When the glue is filled, the receiving groove overflows into the receiving groove, which is convenient for judging whether the glue injection is completed. The receiving groove can also prevent the anti-glue liquid on the bending plate from flowing to the outside.

[0013] (2) The bending plate is supported by a balancing block, a sealing strip, and a convex block, so that after the bending plate is placed together with the window frame, the bending plate and the window frame are kept parallel, thereby improving the connection accuracy between the window frame and the bending plate, and between the window frames.

[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] Example:

[0020] See also Figure 1-3 The utility model provides a technical solution: a door and window corner piece, comprising a bending plate 1, a glue injection hole 4 is provided at the corner of the bending plate 1, a bending portion 2 is provided at the corner of the bending plate 1, a receiving groove 3 is provided on the surface of the bending plate 1, the receiving groove 3 is surrounded by the side of the glue injection hole 4, and the receiving groove 3 can hold excess glue. When the amount of glue injected is slightly too much, the glue is prevented from flowing to the surface of the bending plate 1;

[0021] The balancing block 6 is arranged in an arc shape and is fixedly connected to the surface of the bending portion 2. The balancing block 6 supports the corner of the bending plate 1 and prevents the bending plate 1 from tilting when the bending plate 1 is connected to the window frame.

[0022] The sealing strips 8 are provided in two pieces and are fixedly connected to the lower edge of the surface of the bending plate 1. The sealing strips 8 cooperate with the window frame to seal the lower surface of the bending plate 1, and the sealing strips 8 prevent the glue from freely flowing into the window frame.

[0023] In this embodiment, if Figure 1 and Figure 2 As shown, a groove 5 is provided on the surface of the bending plate 1, and a protrusion 7 is provided on the other side of the bending plate 1, and the position of the protrusion 7 corresponds to that of the groove 5. The groove 5 and the protrusion 7 are simultaneously formed on the surface of the bending plate 1 by stamping. When the protrusion 7 contacts the window frame, it cooperates with the balance block 6 to provide multi-point support for the bending plate 1.

[0024] In this embodiment, if Figure 3 As shown, a limiting groove 10 is provided on the lower edge of the surface of the bending plate 1, and the sealing strip 8 is placed inside the limiting groove 10. The limiting groove 10 improves the stability of the connection between the bending plate 1 and the sealing strip 8, and can also limit the position deviation of the sealing strip 8, thereby playing a positioning role for the sealing strip 8.

[0025] In this embodiment, if Figure 3 As shown, an overflow port 9 is provided on the surface of the sealing strip 8 , and when the glue enters between the bending plate 1 and the window frame, the air is discharged through the overflow port 9 .

[0026] 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. At this time, the balance block 6 and the protrusion 7 are in contact with the window frame. Since the balance block 6 and the protrusion 7 are in a protruding state on the bending plate 1, there is a gap between the bending plate 1 and the window frame. When the glue injection equipment is aligned with the glue injection hole 4, the glue is sent to the gap between the bending plate 1 and the window frame. The sealing strip 8 limits the flow range of the glue to ensure that the glue completely fills the gap, thereby improving the glue quality and making the connection between the bending plate 1 and the window frame more stable.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
