Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a die-cast aluminum and stainless steel combined expansion glue injection corner code. Background Art

[0002] When assembling door and window frames, the profiles need to be connected by using angle brackets. Normally, the profiles are connected at 90 degrees, which requires making the ends of the profiles at a 45-degree angle and then connecting the two profiles with a 90-degree angle bracket.

[0003] As a result, various kinds of angle codes have appeared on the market. For example, patent number CN207686542U discloses a connecting angle code structure, which is a typical angle code connection device. The angle code is fixed and tightened by a slotted pin. The groove on the surface of the angle code body facilitates the guidance of glue filling and achieves a sealing effect with high air tightness.

[0004] For example, patent number CN207598131U discloses a movable corner bracket for doors and windows provided by the utility model, which includes two vertically arranged corner bracket substrates, and the corner bracket substrates between the bending part and the locking part are provided with a glue injection channel, so that the fixing effect between the corner bracket and the door and window frame is greatly enhanced, the door and window are not easily deformed, and outdoor dust is not easy to enter the room.

[0005] After referring to various angle brackets on the market, we found that the die-cast angle brackets on the market are easy to break, have low strength, and poor wind pressure and earthquake resistance. They are easy to loosen and crack during transportation, have high subsequent maintenance costs, poor safety performance, and high risks. Utility Model Content

[0006] The utility model aims to provide a die-cast aluminum and stainless steel combined expansion glue injection angle code to solve the technical problems of easy breakage and low strength of the die-cast angle code.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0009] As a further solution of the utility model: an upper marble groove is arranged at the lower end of the upper corner code substrate, and a lower marble groove is arranged at the upper end of the lower corner code substrate. The lower marble groove and the upper marble groove form a circular through groove, and glue-injected marbles are rolled in the circular through groove.

[0010] As a further solution of the utility model: the upper end of the upper angle code base and the lower end of the lower angle code base are both provided with a pad support connected to the pad.

[0011] As a further solution of the utility model: the pad support is a cylinder, and a plurality of clamping protrusions distributed in a ring array are arranged on the outer circumference of the pad support.

[0012] As a further solution of the utility model: the upper angle code substrate includes an upper substrate, and a substrate flange is arranged at the lower end of the upper substrate; the lower angle code substrate includes a lower substrate, and a lower flange matching with the substrate flange is arranged at the upper end of the lower substrate.

[0013] As a further solution of the utility model: the base flange and the lower flange are both provided with a snap-in pin and a snap-in hole, and the snap-in pin and the snap-in hole are transitionally plug-fitted.

[0014] As a further solution of the utility model: an upper glue injection groove is arranged at the lower end of the upper corner code base, and a lower glue injection groove is arranged at the upper end of the lower corner code base, and the upper glue injection groove and the lower glue injection groove are combined to form a glue injection flow channel.

[0015] Beneficial effects of the utility model:

[0016] (1) The upper and lower corner bracket substrates are made of die-cast aluminum, while the upper and lower pads are made of stainless steel. The upper pad is flush with the upper end surface of the upper corner bracket substrate, and the lower pad is flush with the lower end surface of the lower corner bracket substrate. The pad is used to strengthen the corner bracket substrate, thereby improving the overall strength of the entire injection-molded corner bracket and greatly improving the wind pressure resistance and earthquake resistance of the corner bracket.

[0017] (2) Add glue injection marbles into the glue injection corner code. During the glue injection process, the glue injection marbles roll along the marble groove under the action of the glue liquid. When they roll to one side of the glue overflow groove, the glue liquid will fill the glue injection groove, ensuring comprehensive and uniform glue injection.

[0018] (3) During the glue injection process, the glue injection beads play a guiding or positioning role, ensuring that the glue can be evenly and fully filled into the gap between the corner bracket and the connecting part. This can not only improve the sealing of the connection and prevent the intrusion of external factors such as moisture and dust, but also improve the durability and stability of the overall structure.
