Description

Technical Field

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

[0002] At present, the assembly between door and window profiles, such as between the ends of window frame profiles, between the ends of sash frame profiles, and the installation of door and window center columns, is only assembled and connected by inserting the existing conventional assembly angle code into the profile cavity. The angle code is an accessory that assembles two profiles set at 90° together. Various angle codes have appeared on the market. In order to meet the airtightness of the profile after assembly, it is necessary to inject glue into the angle code. When assembling door and window frames, the profiles need to be connected by using angle codes. Under normal circumstances, the profiles are connected at 90 degrees, which requires the ends of the profiles to be made into a 45-degree angle, and then the two profiles are connected by the angle code at a 90-degree angle. Then, glue is generally injected into the angle code to ensure that the angle code and the profile are connected and fixed reliably to prevent loosening. When injecting glue into the angle code, it is often necessary to first splice the profiles through the angle code. The existing angle code is easy to move when injecting glue, so that the angle code is not fixed tightly to the profile, resulting in glue overflow. Utility Model Content
