Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge installation structure for aluminum alloy doors and windows. Background Art

[0002] Hinge is also called hinge, and its official name is hinge. It is usually composed of two folds, and is a part that connects two parts of an object and enables them to move. Ordinary hinges are used for cabinet doors, windows, etc.; the materials include iron, copper and stainless steel. Pipe hinges are also called spring hinges; they are mainly used to connect furniture door panels, and they generally require a panel thickness of 16 to 20 mm.

[0003] After searching, the existing Chinese patent announcement number is: CN 215108207 U, which provides a hinge. The patent is connected to the first sleeve through a first connecting member, and then connected to the second sleeve through the cooperation of the second connecting member and the connecting sleeve, so that the smoothness of rotation between the first hinge piece and the second hinge piece is improved through the rotation action between the second connecting member and the first connecting member; and because the bearing is made of self-lubricating material, the hinge does not need to add damping oil, and damping oil leakage will not occur. It has better lubrication effect and ensures service life.

[0004] Although the above patent can prevent the leakage of damping oil, the above hinge still has the following problems: a mounting hole is provided on the surface of the hinge. However, when installing with bolts, the bolts are inserted into the mounting holes and then fixed to the aluminum alloy door frame. However, when the doors and windows swing back and forth, the bolts are easily loosened, causing the bolts to separate from the hinges, and then causing the bolts to fall off.

[0005] In view of the above problems, a hinge installation structure for aluminum alloy doors and windows is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a hinge installation structure for aluminum alloy doors and windows, which can solve the problems of the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hinge installation structure for aluminum alloy doors and windows, comprising a first hinge and a second hinge, wherein a second sleeve is fixedly installed on a side of the first hinge close to the second hinge, and a first sleeve is fixedly installed on a side of the second hinge close to the first hinge, a core shaft is slidably connected inside the second sleeve and the first sleeve, and two sliding holes are provided inside the core shaft, and limiting baffles are slidably connected inside the two sliding holes, and return springs are fixedly installed on opposite sides of the two limiting baffles, and opposite ends of the two return springs are respectively fixedly connected to the inside of the two sliding holes, and protrusions are fixedly installed on opposite sides of the two limiting baffles, and the two protrusions respectively slide through the core shaft and extend to the outside of the core shaft.

[0008] Preferably, the surfaces of the two protrusions are both curved.

[0009] Preferably, both the first hinge and the second hinge are provided with mounting holes.

[0010] Preferably, a sliding groove is provided on one side of the first hinge, and a sliding block is slidably connected inside the sliding groove.

[0011] Preferably, the sliding groove and the sliding block are both T-shaped, and a cover plate is fixedly mounted on the sliding block.

[0012] Preferably, a moving groove is provided on one side of the first hinge, a moving block is slidably connected inside the moving groove, a baffle is fixedly installed on one side of the moving block, and the baffle is located on one side of the sliding groove.

[0013] Preferably, a fixed guide rod is fixedly installed inside the movable groove, and the surface of the fixed guide rod is slidably connected to the inside of the movable block.

[0014] Preferably, an elastic spring is movably sleeved on the surface of the fixed guide rod, one end of the elastic spring close to the moving block is fixedly connected to the moving block, and one end of the elastic spring away from the moving block is fixedly connected to the inside of the moving groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The hinge installation structure of the aluminum alloy door and window pushes the sliding block into the interior of the sliding groove, so that the cover plate covers the installation hole, thereby covering the installation hole, thereby avoiding the movement of the screw to the greatest extent, thereby preventing the screw from falling off to the greatest extent, reducing the loosening of the screw, and ensuring the stability of the connection.

[0017] (2) The hinge installation structure of the aluminum alloy door and window allows the core shaft to pass through one end of the first shaft sleeve, so that the two protrusions are reset by the elastic force of the two reset springs, thereby blocking the core shaft, thereby completing the connection between the first hinge and the second hinge, thereby facilitating the connection and installation of the first hinge and improving the convenience of installation.

[0018] (3) The hinge installation structure of the aluminum alloy door and window, after the sliding block is installed in the sliding groove, the baffle plate is no longer pushed, so that the baffle plate and the moving block are reset by the elastic force of the elastic spring, and then the baffle plate blocks the sliding block, thereby preventing the sliding block from sliding inside the sliding groove and preventing the sliding phenomenon, thereby ensuring the use effect of the cover plate.
