Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to an easily adjustable building curtain wall hinge. Background Technology

[0002] Building curtain walls refer to the non-load-bearing exterior wall cladding of a building, typically composed of panels (glass, metal, stone, ceramic, etc.) and a supporting structure behind them (aluminum beams and columns, steel structures, glass ribs, etc.). Building curtain walls are composed of a supporting structure system and panels, and can have a certain displacement capacity relative to the main structure. They are building exterior envelope structures or decorative structures that do not share the loads of the main structure.

[0003] A curtain wall is the exterior wall enclosure of a building. It is non-load-bearing and hangs up like a curtain, hence it is also called a suspended wall. In order to allow for normal ventilation, operable unit panels need to be installed at intervals on the curtain wall. Most of the unit panels are installed by hinges, and the principle is similar to that of conventional building windows. During the installation of the curtain wall, installation errors are prone to occur, resulting in gaps between the curtain walls that are too small or too large. However, the existing curtain wall hinges have poor adjustability, making it difficult to adjust the gaps after installation. Utility Model Content

[0004] The purpose of this utility model is to provide an easily adjustable building curtain wall hinge to solve the problem mentioned in the background art that the existing curtain wall hinges have poor adjustability and are difficult to adjust the gap after installation.

[0006] Preferably, the fixing page is plate-shaped, and the first mounting plate is symmetrically distributed in two groups on the surface of the fixing sleeve.

[0007] Preferably, the rotating shaft is cylindrical in shape, and the rotating shaft is symmetrically distributed in two sets on both sides of the rotating connecting block.

[0008] Preferably, the ball bearings and the rotating shaft are tumblingly connected, and the rotating sleeves are movably connected via the ball bearings and the rotating shaft. The rotating sleeves are arranged in six groups on the surface of the movable page.

[0009] Preferably, the movable page is rotatably connected to the fixed page via a rotating sleeve, ball bearings, and a rotating shaft, and the limiting plate is in the shape of a circular plate.

[0010] Preferably, the lead screw is movably connected to the movable leaf via a limiting plate, and the surface of the rotating head is provided with a cross groove.

[0011] Preferably, the movable block is block-shaped and is slidably connected to the movable page via a lead screw.

[0024] An easily adjustable building curtain wall hinge includes a fixed hinge 1 for installation on a fixed unit curtain wall. A fixed sleeve 2 is fixedly connected to the surface of the fixed hinge 1, and a first mounting plate 3 is fixedly connected to the surface of the fixed sleeve 2. The fixed sleeve 2 and the first mounting plate 3 are used to install the fixed hinge 1 on the fixed unit curtain wall. The first mounting plate 3 cooperates with mounting bolts. A rotating connecting block 4 is fixedly connected to the surface of the fixed hinge 1, and a rotating shaft 5 is fixedly connected to the surface of the rotating connecting block 4. The rotating connecting block 4 and the rotating shaft 5 are used to realize the rotation of a movable hinge 8, thereby allowing the movable unit curtain wall to rotate. Ball bearings 6 are embedded in the surface of the rotating shaft 5, and a rotating sleeve 7 is movably connected to the surface of the ball bearings 6. The ball bearings 6 and the rotating sleeve 7 are used to change the sliding friction between the rotating shaft 5 and the movable hinge 8 into rolling friction, thereby effectively reducing wear between the rotating shaft 5 and the movable hinge 8, and thus improving the service life of the hinge. The movable hinge 8 is fixedly connected to the surface of the rotating sleeve 7. The movable page 8 is used to install on the movable unit curtain wall. The movable page 8 is internally connected to a limit plate 9, which limits the lead screw 10 so that the lead screw 10 can only rotate in place. The lead screw 10 is fixedly connected to the surface of the limit plate 9. The lead screw 10 is used to drive the moving block 12 to move up and down. The end of the lead screw 10 away from the limit plate 9 is fixedly connected to a rotating head 11, which is used to facilitate the rotation of the lead screw 10 by the operator. The moving block 12 is movably connected to the surface of the lead screw 10. The moving block 12 is used to drive the movable sleeve 13 and the second mounting plate 14 to move up and down, thereby driving the movable unit curtain wall to move up and down, and thus adjusting the gap between the two curtain walls. The movable sleeve 13 is fixedly connected to the surface of the moving block 12. The second mounting plate 14 is fixedly connected to the surface of the movable sleeve 13. The movable sleeve 13 and the second mounting plate 14 are used to install the movable page 8 on the movable unit curtain wall. The second mounting plate 14 is used in conjunction with the mounting bolts.

[0025] Furthermore, the fixing page 1 is plate-shaped and is used to install on the fixed unit curtain wall. The first mounting plate 3 is symmetrically distributed in two sets on the surface of the fixing sleeve 2. The fixing sleeve 2 and the first mounting plate 3 are used to install the fixing page 1 on the fixed unit curtain wall. The first mounting plate 3 is used in conjunction with the mounting bolts.

[0026] Furthermore, the rotating shaft 5 is cylindrical in shape, and two sets of rotating shaft 5 are symmetrically distributed on both sides of the rotating connecting block 4. The rotating connecting block 4 and the rotating shaft 5 are used to realize the rotation of the movable page 8, so that the movable unit curtain wall can rotate.

[0027] Furthermore, the ball bearing 6 and the rotating shaft 5 are in a rolling connection, and the rotating sleeve 7 is in a movable connection with the rotating shaft 5 via the ball bearing 6. The rotating sleeve 7 is distributed in six groups on the surface of the movable leaf 8. The ball bearing 6 and the rotating sleeve 7 are used to change the sliding friction between the rotating shaft 5 and the movable leaf 8 into rolling friction, thereby effectively reducing the wear between the rotating shaft 5 and the movable leaf 8, and thus improving the service life of the hinge.

[0028] Furthermore, the movable page 8 is rotatably connected to the fixed page 1 via the rotating sleeve 7, ball bearing 6 and rotating shaft 5. The movable page 8 is used to install on the movable unit curtain wall. The limiting plate 9 is in the shape of a circular plate and is used to limit the lead screw 10, so that the lead screw 10 can only rotate in place.

[0029] Furthermore, the lead screw 10 is movably connected to the limiting plate 9 and the movable page 8. The lead screw 10 is used to drive the moving block 12 to move up and down. The surface of the rotating head 11 is provided with a cross groove. The rotating head 11 is used to facilitate the operator to rotate the lead screw 10.

[0030] Furthermore, the movable block 12 is block-shaped and is slidably connected to the movable page 8 via the lead screw 10. The movable block 12 is used to drive the movable sleeve 13 and the second mounting plate 14 to move up and down, thereby driving the movable unit curtain wall to move up and down, and thus adjusting the gap between the two curtain walls. The movable sleeve 13 and the second mounting plate 14 are slidably connected to the movable page 8 via the movable block 12. The second mounting plate 14 is symmetrically distributed in two sets on the surface of the movable sleeve 13. The movable sleeve 13 and the second mounting plate 14 are used to install the movable page 8 on the movable unit curtain wall. The second mounting plate 14 is used in conjunction with the mounting bolts.

[0031] Working principle: Rotating the rotating head 11 drives the lead screw 10 to rotate, which controls the moving block 12 to move the movable sleeve 13 and the second mounting plate 14, thereby moving the movable unit curtain wall and adjusting the gap between the two curtain walls.

[0032] The ball bearing 6 and the rotating sleeve 7 can change the sliding friction between the rotating shaft 5 and the moving leaf 8 into rolling friction, thereby effectively reducing the wear between the rotating shaft 5 and the moving leaf 8 and thus improving the service life of the hinge.
