Detailed implementation manners

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides an adjustable door and window hinge as shown in Figures 1-6 Figure 5, which includes a fixed page 1. A movable page 2 is arranged at the top of the fixed page 1. A rotating component 3 for rotating the movable page 2 is arranged on the opposite side of the fixed page 1 and the movable page 2. A sliding block 4 is hinged at the bottom of the movable page 2. A limiting component for restricting the moving direction of the sliding block 4 is arranged at the connection between the sliding block 4 and the fixed page 1. A blocking block 5 for restricting the moving distance of the sliding block 4 is arranged at the top of the fixed page 1. An adjusting component 6 for adjusting the position of the blocking block 5 is arranged at the connection between the blocking block 5 and the fixed page 1. The rotating component 3 includes a second rotating block 302 hinged at the top end of the fixed page 1. A first rotating block 301 is hinged at the top of the second rotating block 302. The first rotating block 301 is hinged at the bottom of the movable page 2.

[0023] It should be noted that when the arranged movable page 2 needs to rotate on the fixed page 1, it directly rotates on the fixed page 1 through the first rotating block 301 and the second rotating block 302. When the movable page 2 rotates, the sliding block 4 is pushed towards the side of the blocking block 5. The arranged blocking block 5 is used to restrict the moving distance of the sliding block 4, so as to restrict the rotation angle of the movable page 2 by restricting the moving distance of the sliding block 4, thereby realizing the adjustment of the rotation angle of the movable page 2 by adjusting the position of the blocking block 5.

[0024] Specifically, the limiting component includes a connecting rod 7 fixedly connected to the bottom of the sliding block 4. A limiting block 8 is arranged at the bottom of the fixed page 1. The limiting block 8 is fixedly connected to the bottom end of the connecting rod 7. A sliding hole 101 is formed in the middle of the fixed page 1. The connecting rod 7 is inserted and connected inside the sliding hole 101.

[0025] It should be noted that one end of the sliding block 4 is hinged to the bottom of the movable page 2. When the movable page 2 rotates on the top of the fixed page 1, it will drive the other side of the sliding block 4 to move on the top of the fixed page 1. The bottom end of the sliding block 4 fits but is not fixed to the top end of the fixed page 1, and the end of the fixed page 1 fits but is not fixed to the top end of the limiting block 8. The sliding block 4 and the limiting block 8 are connected by a connecting rod 7. The set connecting rod 7 is adapted to the opened sliding hole 101, and the horizontal longitudinal cross-sectional areas of the sliding block 4 and the limiting block 8 are both larger than the horizontal transverse cross-sectional area of the sliding hole 101, so that neither the sliding block 4 nor the limiting block 8 can pass through the sliding hole 101. Therefore, when the other side of the sliding block 4 moves, the sliding block 4 drives the connecting rod 7 to slide inside the sliding hole 101, so as to limit the moving direction of the other side of the sliding block 4 through the connecting rod 7 and the sliding hole 101.

[0026] Specifically, the adjusting assembly 6 includes a bottom plate 603 arranged at the bottom of the fixed page 1. The top end of the bottom plate 603 is fixedly connected with a threaded cylinder 602. A positioning bolt 601 is threaded through the middle of the blocking block 5. The bottom end of the positioning bolt 601 is inserted into the threaded cylinder 602. A plurality of limiting holes 604 are symmetrically opened at the center of the top end of the fixed page 1. The top end of the bottom plate 603 is symmetrically fixedly connected with limiting posts 605. The limiting posts 605 are inserted into the limiting holes 604.

[0027] It should be noted that the number of the set limiting posts 605 is two, both of which are fixed to the top end of the bottom plate 603, and the two limiting posts 605 are respectively inserted into the two limiting holes 604. The limiting posts 605 are restricted by the limiting holes 604 and cannot move horizontally. The rotation of the bottom plate 603 is restricted by the two limiting posts 605 that restrict movement. An equilateral hexagon hole is opened at the top of the positioning bolt 601. When the positioning bolt 601 needs to be rotated, it can be directly rotated by a hexagonal wrench that matches it. When the position of the blocking block 5 needs to be fixed, the positioning bolt 601 passes through the blocking block 5 and is threaded through the threaded cylinder 602. By screwing the positioning bolt 601, the blocking block 5 and the bottom plate 603 are both squeezed towards one side of the fixed page 1, so as to fix the position of the blocking block 5 by extrusion.

[0028] Furthermore, when the position of the blocking block 5 needs to be adjusted, first rotate the positioning bolt 601 with a hexagonal wrench to release the blocking block 5 on the top of the threaded cylinder 602, then move the position of the blocking block 5. When it moves to the required position, then tighten the positioning bolt 601 with a hexagonal wrench. The blocking block 5 and the bottom plate 603 are squeezed and fixed at the required position by the positioning bolt 601 and the threaded cylinder 602.

[0029] A kind of door and window, adopting the above adjustable door and window hinge, includes a frame body 9, the frame body 9 is fixedly connected to the bottom end of the fixed page 1, and a window 10 is inserted and connected inside the frame body 9, and the window 10 is fixedly connected to the top end of the movable page 2.

[0030] It should be noted that holes for bolts to pass through are provided on both the fixed page 1 and the movable page 2. When it is necessary to fix the window 10 to the frame body 9, first fix the fixed page 1 to the top of the frame body 9 through bolts, then move the window 10 to the movable page 2, and fix the window 10 to the movable page 2 through bolts. When it is necessary to rotate the window 10, it rotates on the frame body 9 through the hinge.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
