Description

Technical Field

[0001] This utility model relates to the field of door and window connectors, and in particular to a PVC door and window mullion connector. Background Technology

[0002] The mullion connector for PVC windows and doors is a core hardware accessory used to connect the mullion to the frame / sash of windows and doors. Its core function is to ensure that the mullion (the horizontal / vertical profile that separates the window glass and enhances the overall rigidity) is firmly spliced ​​with the main frame or sash, while ensuring the sealing, stability and service life of the windows and doors. It is a key component for PVC windows and doors to achieve the "large size, multi-cavity" design.

[0003] However, the existing mullion connectors for PVC doors and windows have certain drawbacks in use. First, the connectors have poor resistance to deformation and are prone to deformation under external forces. Second, the protective effect of the connector's fixing base is poor, and the fixing base is easily damaged.

[0004] Therefore, it is necessary to propose a mullion connector for PVC doors and windows to solve the above problems. Utility Model Content

[0008] Preferably, the protective structure includes a fixing pad, an anti-slip pad, a perforation, a protective base, a left connecting clip, and a right connecting clip. The protective base has a perforation in the middle. The left connecting clip is provided on one outer surface of the protective base, and the right connecting clip is provided on the other outer surface of the protective base. The inner walls of both the left and right connecting clips are provided with anti-slip pads, and the lower outer surface of the protective base is provided with a fixing pad.

[0009] Preferably, the outer surfaces of both sides of the anti-deformation frame are fixedly connected to the outer surfaces of one side of the bottom connecting frame and the top connecting frame; the outer walls of the bottom connecting frame and the top connecting frame are fixedly connected to the outer walls of the rivets; the inner wall of the anti-deformation frame is fixedly connected to the outer wall of the reinforcing insert; the rear outer surface of the top connecting frame is fixedly connected to the front outer surface of the connecting base by rivets; and the lower outer surface of the bottom connecting frame is fixedly connected to the upper outer surface of the fixed base by rivets.

[0010] Preferably, one outer surface of the protective base is fixedly connected to one outer surface of the left connecting clip, and the other outer surface of the protective base is fixedly connected to one outer surface of the right connecting clip. The inner walls of both the left and right connecting clips are fixedly connected to the outer wall of the anti-slip pad.

[0012] Compared with the prior art, this utility model provides a mullion connector for PVC doors and windows, which has the following advantages: 1. This type of PVC window and door mullion connector, through the setting of an anti-deformation structure, allows the anti-deformation frame to be installed on the fixed base and connecting base via rivets, a top connecting frame, and a bottom connecting frame during use. The anti-deformation frame and reinforcing plate can improve the anti-deformation capability of the mullion connector. This anti-deformation structure can improve the anti-deformation capability of the connector and prevent the connector from deforming under the action of external force.

[0013] 2. This type of PVC window and door mullion connector, through the set protective structure, allows the protective base to be installed on the lower end of the fixed base via the left and right connecting clips during connector installation.
