Description

Technical Field

[0001] This utility model relates to the field of building door and window hardware components and metal profile processing, specifically a quick-install aluminum alloy door and window frame. Background Technology

[0002] Currently, aluminum alloy door and window installations commonly use traditional glue-injected corner brackets or screw fixing methods, which have the following technical drawbacks: low installation efficiency (traditional corner brackets require on-site glue injection and waiting for curing, which takes more than 2 hours and depends on the operator's skill level); poor sealing performance (the glue is prone to aging and cracking, leading to water and air leakage at the corners, especially in cold regions where the glue becomes brittle at low temperatures); high precision requirements (a deviation of more than 0.5mm in profile cutting necessitates rework, and manual correction takes more than 30% of the total installation time); difficult maintenance (disassembling glued corner brackets can damage the profiles, and replacement requires complete window removal); although quick-installation solutions such as spring-loaded corner brackets have emerged in the market, they still have defects such as easy fatigue and breakage of the clips, lack of physical sealing, and inaccurate positioning due to the absence of guide grooves. Utility Model Content

[0003] To solve the above problems, this utility model provides the following technical solution: a quick-install aluminum alloy door and window frame, including door and window profiles and locking corner brackets. The door and window profiles cooperate with the positioning protrusions on the inner sides of the two arms of the locking corner brackets through guide grooves provided on the inner side of the corners. The locking corner brackets are right-angled, and bidirectional elastic claws are symmetrically provided at the ends of the two arms. A pre-installed sealing gasket is embedded on the outer surface of the locking corner brackets.

[0004] Preferably, the guide groove has a trapezoidal cross-section, with the long base facing the inside of the profile and the short top facing the outside of the profile, and the depth is 1 / 3 to 1 / 2 of the profile wall thickness.

[0005] Preferably, the end of the bidirectional elastic claw is provided with a guide slope with an inclination angle of 15° to 30°, and the material is phosphor bronze. The width in the free state is 1 to 2 mm larger than the inner diameter of the profile cavity.

[0006] Preferably, the pre-installed sealing gasket is made of EPDM rubber with a thickness of 1.5 to 2 mm.

[0007] Preferably, the inner sides of the two arms of the locking bracket are provided with positioning protrusions, and the bottom width of the guide groove is 0.1 to 0.3 mm larger than the positioning protrusions.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] By combining the guide groove of the door and window profile with the positioning protrusion of the locking angle bracket, along with the innovative design of bidirectional elastic claws and pre-installed sealing gaskets, rapid installation and reliable sealing of aluminum alloy doors and windows are achieved. The trapezoidal cross-section design of the guide groove, the guide bevel structure of the bidirectional elastic claws, and the synergistic effect of the pre-installed EPDM sealing gaskets improve installation efficiency by over 80%, eliminates the need for adhesive curing, ensures stable sealing performance, and provides a ±1.5mm installation tolerance. It also supports non-destructive disassembly and maintenance, solving the technical challenge of balancing installation efficiency and sealing performance in traditional doors and windows.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1-2 As shown, the quick-install aluminum alloy door and window frame of this embodiment includes a door and window profile 1 and a locking corner bracket 2. The door and window profile 1 cooperates with the positioning protrusions 201 on the inner side of the corner of the locking corner bracket 2 through the guide groove 101 provided on the inner side of the corner. The locking corner bracket 2 is right-angled, and the ends of the two arms are symmetrically provided with bidirectional elastic claws 3. The outer surface of the locking corner bracket 2 is embedded with a pre-installed sealing gasket 4.

[0016] The guide groove 101 has a trapezoidal cross-section, with the long base facing the inside of the profile and the short top facing the outside of the profile, and the depth is 1 / 3 to 1 / 2 of the profile wall thickness.

[0017] The end of the bidirectional elastic claw 3 is provided with a guide slope 301 with an inclination angle of 15° to 30° and is made of phosphor bronze. Its width in the free state is 1 to 2 mm larger than the inner diameter of the profile cavity.

[0018] The pre-installed sealing gasket 4 is made of EPDM rubber with a thickness of 1.5 to 2 mm.

[0019] The inner sides of the two arms of the locking bracket 2 are provided with positioning protrusions 201, and the bottom width of the guide groove 101 is 0.1 to 0.3 mm larger than the positioning protrusions 201.

[0020] The working principle of this utility model is as follows: when the bidirectional elastic claws 3 of the locking corner bracket 2 are inserted into the guide groove 101 of the door and window profile 1, the guide inclined surface 301 is used to achieve automatic centering and positioning. At the same time, the positioning protrusion 201 and the trapezoidal section of the guide groove 101 form a precise fit. During installation, the bidirectional elastic claws 3 are deformed by pressure and automatically rebound to clamp the inner wall of the profile. With the compression deformation of the pre-installed sealing gasket 4, physical sealing is achieved. Thus, the door and window frame corners can be quickly assembled and permanently sealed without the need for adhesive fixation.
