Description

Technical Field

[0001] This utility model relates to the field of door and window corner bracket technology, and more specifically, to an aluminum alloy door and window corner bracket connection structure. Background Technology

[0002] Window corner brackets are metal or plastic products used to support the corners of doors and windows. They have a fixing and fastening function, making the installation of doors and windows more stable. They can also protect the edges of doors and windows from damage caused by impacts and other external factors.

[0003] Existing corner brackets typically consist of an L-shaped bracket body. To save materials, the bracket body is hollow. Meanwhile, the outer surface of the bracket body has adhesive channels and bolt holes. Connecting bolts in the bolt holes connect the bracket to the door / window profiles. Adhesive is then injected into the channels to bond the bracket to the profiles. After prolonged use, this type of bracket structure is prone to water seepage at the bolt holes. Since the adhesive is only thinly applied to the surface of the bracket, water ingress affects the bonding strength, impacting the strength and lifespan of the doors and windows.

[0004] A search revealed that Chinese patent CN222615187U discloses a novel aluminum alloy door and window corner bracket connection structure. This structure incorporates an adhesive injection groove within the corner bracket body and an adhesive injection plate within the door and window profile. During installation, the adhesive injection plate is inserted into the groove and adhesive is injected, allowing the adhesive to penetrate deep into the corner bracket body. This significantly improves bonding strength, thereby extending the service life and strength of the doors and windows. Furthermore, the adhesive injection groove saves materials, and the adhesive injection plate further enhances the strength of the profile, making this structure worthy of widespread adoption.

[0005] In actual use, the above-mentioned new aluminum alloy door and window corner bracket connection structure requires the use of multiple bolts for fixing when connecting two door and window profiles with the corner bracket body. Each bolt needs to be tightened one by one, which is cumbersome and time-consuming. Furthermore, only the corner bracket body is inserted into the two door and window profiles, which can cause slight loosening during the connection process, thus affecting the connection between the two door and window profiles. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides an aluminum alloy door and window corner bracket connection structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An aluminum alloy door and window corner bracket connection structure includes two first profiles, a corner bracket body is provided between the two first profiles, a connecting component and two protective mechanisms are installed inside the corner bracket body, and the two protective mechanisms are installed on one side of the connecting component.

[0009] The connecting assembly includes a threaded rod, which is threadedly connected to the corner bracket body and the first profile. A movable plate is threadedly connected to the outer side of the threaded rod. A first pushing block is fixedly connected to one side of the movable plate. First sliders are fixedly connected to both sides of the first pushing block. A second slider is fixedly connected to the top of the movable plate. Connecting grooves are formed inside both of the first profiles. A moving rod is slidably connected inside the corner bracket body. A first sliding groove is formed at the bottom of the moving rod. A second pushing block is fixedly connected to the top of the moving rod. Third sliding blocks are fixedly connected to both sides of the second pushing block. The inner side of the first sliding groove is slidably connected to the second slider. Two first sliding plates are slidably connected inside the corner bracket body. A second sliding groove is formed on one side of the first sliding plate. The inner side of the second sliding groove is slidably connected to the first slider. Two second sliding plates are slidably connected inside the corner bracket body. A third sliding groove is formed on one side of the second sliding plate. The inner side of the third sliding groove is slidably connected to the third sliding block. A limiting rod is fixedly connected to one end of both the second sliding plate and the first sliding plate. The limiting rod is engaged with the inner side of the connecting groove.

[0010] By adopting the above technical solution, the two first profiles and the corner bracket can be connected together by rotating a single threaded rod, thereby simplifying the installation process and improving work efficiency.

[0011] As a further description of the above technical solution: the protective mechanism includes a reinforcing cavity, which is opened inside the corner code body. A first reinforcing plate and a second reinforcing plate are fixedly connected inside the reinforcing cavity, and the second reinforcing plate is installed on one side of the first reinforcing plate.

[0012] By adopting the above technical solution, the strength of the corner bracket body can be enhanced by the first and second reinforcing plates, thereby effectively resisting deformation caused by external forces.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a connecting component, compared with the existing technology, the movement of the movable plate can push the two limiting rods to engage with the connecting groove, which can quickly connect the two first profiles together, reducing the complicated process of traditional multiple bolt fixing, simplifying the installation process and operation, and shortening the installation time of the two first profiles to improve installation efficiency. Furthermore, by using the protruding teeth on one side of the two limiting rods to engage with the connecting groove, a stable connection can be formed between the corner bracket and the first profile, thereby ensuring the stability of the connection.

[0015] 2. By setting up a protective mechanism, compared with the existing technology, the rigidity and load-bearing capacity of the corner bracket body can be increased by using the first and second reinforcing plates on both sides of the corner bracket body. Furthermore, the bending elastic deformation of the first and second reinforcing plates can absorb external impact energy, thereby effectively resisting deformation caused by external forces and increasing the stability of the connection with the two first profiles.
