Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aluminum alloy door and window technology, specifically relating to a sliding and adjustable aluminum alloy slider for installing aluminum alloy door and window frames. Background Technology
[0002] Aluminum alloy doors and windows refer to doors and windows made from extruded aluminum alloy profiles for frames, mullions, and sashes. The quality of aluminum alloy doors and windows can be roughly judged from factors such as the selection of raw materials (aluminum profiles), the surface treatment and internal processing quality, and the price. Due to its high strength, light weight, high precision, durability, and ease of processing, aluminum alloy has always been the preferred material for building exterior windows. Before assembly, aluminum alloy doors and windows require processing steps including material selection and cutting, frame, mullion, and sash fabrication, hardware assembly, frame and sash assembly, glass installation, sealant application, and finished product inspection. Each step in the aluminum alloy door and window manufacturing process is important, with the opening form of each profile and the type of installation accessories being particularly crucial. The sealing performance of the frame and structure directly affects the watertightness of the aluminum alloy doors and windows.
[0003] Currently, aluminum alloy window frames are generally installed using three common methods: fasteners, expansion bolts, and screws embedded in the subframe. The primary installation method for aluminum formwork windows and doors is expansion bolt installation. This method involves drilling mounting holes in the aluminum alloy window frame and using expansion bolts to connect the frame to the structure. The drawback of this method is its susceptibility to leakage. Leaking water and moisture can enter the window frame through the mounting holes and seep into the room. Over time, acids and alkalis in the air can corrode and oxidize the bolt holes and expansion bolts, affecting the safety and watertightness of the aluminum alloy windows and doors. Utility Model Content
[0004] The purpose of this utility model is to provide a sliding adjustable aluminum alloy slider for installing aluminum alloy door and window frames that is simple in structure, easy to use, safe and reliable, and improves the water tightness and service life of aluminum alloy doors and windows.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A sliding adjustable aluminum alloy slider for installing aluminum alloy door and window frames is provided, comprising an aluminum alloy window frame profile and a galvanized fastener connected by the aluminum alloy slider. The features are: a window frame groove is provided on the outer side of the window frame profile; a groove is provided on the slider profile; the aluminum alloy slider is provided with a limit switch; a nail wire is provided on the aluminum alloy slider; and a screw extension cavity is provided on the aluminum alloy slider. The aluminum alloy slider is sized to match the aluminum alloy window frame groove, and the aluminum alloy slider is embedded within the frame groove, allowing the slider to slide freely in one direction within the groove. The aluminum alloy fastener has a screw extension cavity that matches a self-tapping screw for connection; the galvanized fastener is connected to the aluminum alloy slider; and the galvanized fastener is connected to the structure via stainless steel expansion bolts.
[0006] Furthermore, aluminum alloy door and window frames do not require drilling installation holes, reducing the leakage rate of the frames.
[0007] Furthermore, the aluminum alloy slider can slide freely within the frame slot, and its positioning is not restricted.
[0008] Furthermore, the galvanized fastener is connected to the aluminum alloy slider, and the aluminum alloy slider has a bottom hole.

[0010] 1. This utility model effectively solves the problem of precision in existing door and window processing and installation, greatly reduces production and installation technology, and improves installation and production efficiency.
[0011] 2. The fixing block of this utility model has a large thickness and rigidity, which greatly improves the installation strength of door and window frames and ensures the safety of door and window frames.
[0012] 3. The fixing block of this utility model is a clamping sliding structure, which does not require drilling holes in the frame and effectively solves the problem of water leakage from the expansion screw holes.
[0013] 4. The clamping structure of the fixing block of this utility model does not require drilling holes in the frame, effectively solving the problem of adjustability, thereby improving the lifespan, refinement, and aesthetics of the door and window frame. Attached Figure Description
