Description

Technical Field

[0001] The utility model relates to the technical field of door and window slide rails, in particular to a door and window slide rail structure. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and sashes, referred to as aluminum doors and windows. Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material of load-bearing rods (rods that bear and transmit deadweight and loads) and doors and windows composited with wood and plastic, referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows.

[0003] In the prior art, the sliding rail structure of doors and windows mostly adopts the sliding rail set on the frame to cooperate with the groove in the window frame for sliding. Long-term use will lead to poor cooperation between the sliding rail and the sliding groove, which will easily cause jamming between the window and the sliding rail and the door and window derailing in the sliding rail when pushing and pulling. Therefore, we propose a sliding rail structure for doors and windows to solve the above problems. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: See Figure 1-4 The utility model provides a technical solution: a door and window sliding rail structure: including a main frame 1, a slider 2 is provided in the inner cavity of the main frame 1, a bearing 3 is provided in the inner cavity of the slider 2, a connecting rod 4 is provided in the inner cavity of the bearing, rotating rods 5 are provided at both ends of the connecting rod 4, and a roller 11 is provided on one side of the rotating rod 5.

[0018] Wherein, a protective shell 6 is provided on both sides of the slider 2 , and a small bearing 7 is provided in the inner cavity of one side of the protective shell 6 .

[0019] In this embodiment, the main frame 1 is formed by folding and welding stainless steel plates, and four limit plates are installed in the inner cavity, which are also welded. Secondly, stainless steel has the function of corrosion resistance and wear resistance, which can make the service life of the device longer. The slider 2 is provided with two and the inner cavity is fixed with two bearings 3 and evenly distributed. The inner cavity of the two bearings 3 is fixed with a connecting rod 4, and the two ends of the two connecting rods 4 are respectively fixed with a turning rod 5. The turning rod 5 is smaller than the area of ​​the connecting rod 4. A roller 11 is provided at one end of the four turning rods 5. The material of the roller 11 is rubber. The above structure is a slide rail structure. The above slide rail structure can effectively solve the problem that the fit between the slide rail and the slide groove is not high due to long-term use, and the window and the slide rail are prone to jamming and the door and window are derailed in the slide rail when pushing and pulling. At the same time, the roller 11 made of rubber can greatly reduce the sound when switching, thereby greatly improving the usability of the structure. Four protective shells 6 are fixedly provided on both sides of the slider 2 and are evenly distributed on both sides of each bearing 3. A small bearing 7 is fixedly provided in the inner cavity of one end of the small opening of the protective shell 6. A rotating rod 5 is fixedly provided in the inner cavity of the small bearing 7. The small bearing 5 and the bearing 3 can be used together to greatly improve the stability of the structure when pushing and pulling, and also improve the smoothness of the roller 11 when rotating. The protective shell 6 can effectively protect the bearing 3 from damage caused by dust, and can also greatly reduce the entry of dust.

[0020] A slide groove 8 is provided below the main frame 1 , a connecting plate 9 is provided below the sliding block 2 , and a through hole 10 is provided through the top of the connecting plate 9 .
