Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to aluminum alloy door and window slide rails. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and sashes. Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material for 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. Aluminum alloy doors and windows need to be installed with slide rails during use. With the development of technology, such slide rails have more and more functions, making them more convenient to use.

[0003] In view of this, Chinese Patent No. CN211524476U proposes an aluminum alloy door and window slide rail. The staff pushes the limit column, and the limit column moves to squeeze the spring, which will drive the limit block to move and make the limit column move into the fixed plate. Then the staff will clamp the block into the discharge port, and then the staff will release the limit column. At this time, the spring recovers its elasticity and makes the limit column move. The movement of the limit column drives the limit block to move, and the limit block moves to the top of the block to limit the block, which can prevent the block from sliding out of the slot. At the same time, the block can be limited and fixed to prevent the block from falling out of the discharge port when the door and window are carried and transported. However, the above technical solution and the existing aluminum alloy door and window slide rails need to be screwed into the door frame with screws to fix them when in use, which is very troublesome to operate, and the screws are easily corroded by oxidation, which may easily cause the slide rail to fall off in the later stage, thereby reducing the practicality of the device. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide an aluminum alloy door and window sliding rail to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model proposes an aluminum alloy door and window slide rail, comprising a slide rail base, an extrusion type fixing mechanism is arranged at the upper end of the slide rail base, and a press type door and window installation mechanism is arranged inside the slide rail base;

[0006] The extrusion type fixing mechanism includes connecting holes opened at both ends of the slide rail base, a bolt is inserted into the middle position of the bottom of the slide rail base, and the outer wall of one end of the bolt is threadedly connected to the inner wall of the slide rail base, the inner walls of the two connecting holes are inserted with fixing buckles, one side of the two fixing buckles is opened with a connecting groove, a connecting rod is rotatably provided between the inner walls of the two connecting grooves, a first spring is fixedly provided on one side of the inner wall of the slide rail base, and one end of the first spring is in contact with one side of the connecting rod.

[0007] In one example, a rubber pad is fixedly provided on the other side of the two fixing buckles, and one end of the bolt contacts the other side of the connecting rod.

[0008] In one example, three limit bars are fixedly provided at equal distances on the bottom of the slide rail base, and limit grooves are provided at both ends of the inner wall of the slide rail base.

[0009] In one example, the push-type door and window installation mechanism includes pulleys inserted into the two ends of the inner walls of the two limiting grooves, and two connecting blocks are rotatably arranged between the four pulleys.

[0010] In one example, a clamping groove is provided at the middle position of the bottom of the two connecting blocks, and a clamping shaft is inserted through the inner walls of the two clamping grooves.

[0011] In one example, the outer walls of the two clamping shafts are both fixedly provided with second springs, and one end of the two second springs is respectively fixedly connected to one side of the inner walls of the two clamping slots.

[0012] In one example, limiting blocks are fixedly provided on both sides of the inner walls of the two limiting grooves, and a plurality of rubber strips are fixedly provided at equal distances on the top of the slide rail base.

[0013] The aluminum alloy door and window slide rail proposed by the utility model can bring the following beneficial effects:

[0014] 1.
