[0026] See also Figure 1-5 The utility model provides a technical solution: a hinge device for hinged doors and windows, comprising a first hinge 1 and a second hinge 3, two first shaft sleeves 4 are fixedly installed on the side of the first hinge 1 close to the second hinge 3, a second shaft sleeve 6 is fixedly connected to the side of the second hinge 3 close to the first hinge 1, an axis core 7 is slidably connected inside the second shaft sleeve 6 and the two first shaft sleeves 4, a circular plate 5 is fixedly installed at one end of the axis core 7, a threaded rod 10 is threadedly connected to the inner thread of the circular plate 5, a handle 14 is fixedly installed at one end of the threaded rod 10 extending outside the circular plate 5, a moving column 9 is rotatably connected to one end of the threaded rod 10, and the moving column 9 is on the axis core 7 An internal sliding connection is formed, an extrusion block 17 is fixedly installed at one end of the movable column 9, and the shape of the extrusion block 17 is an isosceles trapezoid. Two positioning shafts 19 are fixedly installed inside the shaft core 7, and sliders 18 are slidably connected on the surfaces of the two positioning shafts 19. Bumps 8 are fixedly installed on the two sliders 18. The two bumps 8 are slidably connected inside the shaft core 7, and the two bumps 8 extend to the outside of the shaft core 7. Tension springs 20 are movably sleeved on the two positioning shafts 19, and the opposite ends of the two tension springs 20 are respectively fixedly connected to the two sliders 18, and the opposite ends of the two tension springs 20 are fixedly connected to the inside of the shaft core 7.

[0027] The handle 14 is turned to rotate the threaded rod 10, thereby moving the threaded rod 10 outward, pulling the moving column 9 to slide inside the shaft core 7, so that the squeezing block 17 follows the moving column 9 to move, so that the squeezing block 17 no longer squeezes the two protrusions 8, so that the two protrusions 8 and the two sliders 18 are reset by the tension of the two tension springs 20, so that the two protrusions 8 are retracted into the interior of the shaft core 7, so that the two protrusions 8 no longer protrude from the outside of the shaft core 7, and the shaft core 7 is inserted into the interior of the two first sleeves 4 and the second sleeve 6, and then the handle 14 is turned in the opposite direction to move the moving column 9 and the squeezing block 17 to move, squeeze the two protrusions 8, and then stretch the two tension springs 20, so that the two protrusions 8 protrude from the outside of the shaft core 7, so that the second hinge 3 and the first hinge 1 are connected conveniently, so as to facilitate the assembly of the second hinge 3 and the first hinge 1, improve the convenience of assembling the second hinge 3 and the first hinge 1, and thus reduce the assembly time.

[0028] The first hinge 1 and the second hinge 3 are both provided with mounting holes 2 .

[0029] The installation holes 2 are provided to facilitate fixing the first hinge 1 and the second hinge 3 by bolts.

[0030] An insertion rod 11 is fixedly mounted on one side of the circular plate 5 , and an insertion hole 12 is opened on one side of the movable column 9 , and the insertion rod 11 is slidably connected inside the insertion hole 12 .

[0031] When the movable column 9 moves, the insertion rod 11 will slide inside the insertion hole 12, and then the movable column 9 can be restricted by the setting of the insertion rod 11 and the insertion hole 12 so that the movable column 9 can only slide inside the shaft core 7.

[0032] A steel ball hole 15 is provided on the shaft core 7, and a steel ball 21 is arranged inside the steel ball hole 15. The diameter of the outer side of the steel ball hole 15 is smaller than the diameter of the steel ball 21. The steel ball 21 contacts the movable column 9. A steel ball groove 16 is provided on the inner wall of the first sleeve 4. The steel ball 21 rolls and connects inside the steel ball groove 16. A groove 13 is provided on the surface of the movable column 9.

[0033] When the moving column 9 moves, the steel ball 21 will gradually enter the interior of the groove 13, and then the steel ball 21 will shrink into the interior of the groove 13. The steel ball 21 is no longer located in the steel ball groove 16, and the shaft core 7 is inserted into the interior of the first sleeve 4. When the moving column 9 rotates in the opposite direction, the steel ball 21 is squeezed into the interior of the steel ball hole 15 through the inclined surface of the groove 13, and enters the interior of the steel ball groove 16, so that the steel ball 21 is convenient to contact with the steel ball groove 16. When the first sleeve 4 rotates, the steel ball 21 will roll, so as to reduce the friction between the first sleeve 4 and the shaft core 7, so as to facilitate the rotation of the door and window, reduce the rotation resistance, improve the rotation effect, and at the same time, it is convenient to fix the first sleeve 4 and the shaft core 7, so as to strengthen the stability of the connection between the first hinge 1 and the second hinge 3.

[0034] Working principle:

[0035] The handle 14 is turned to rotate the threaded rod 10, thereby moving the threaded rod 10 outward, pulling the movable column 9 to slide inside the shaft core 7, and causing the extrusion block 17 to move following the movable column 9, so that the extrusion block 17 no longer squeezes the two protrusions 8, and the two protrusions 8 and the two sliders 18 are reset by the tension of the two tension springs 20, so that the two protrusions 8 are retracted into the interior of the shaft core 7, so that the two protrusions 8 no longer protrude from the outside of the shaft core 7, and the shaft core 7 is inserted into the interior of the two first sleeves 4 and the second sleeve 6, and then the handle 14 is rotated in the opposite direction to move the movable column 9 and the extrusion block 17, squeezing the two protrusions 8, and stretching the two tension springs 20, so that the two protrusions 8 protrude from the outside of the shaft core 7, so as to facilitate the connection of the second hinge 3 and the first hinge 1.

[0036] The steel ball 21 is gradually introduced into the groove 13, and then the steel ball 21 is retracted into the groove 13. The steel ball 21 is no longer located in the steel ball groove 16, and then the shaft core 7 is inserted into the first sleeve 4. When the movable column 9 rotates in the opposite direction, the steel ball 21 is squeezed into the steel ball hole 15 through the inclined surface of the groove 13, and enters the steel ball groove 16, so that the steel ball 21 is in contact with the steel ball groove 16. When the first sleeve 4 rotates, the steel ball 21 will roll, so as to reduce the friction between the first sleeve 4 and the shaft core 7.
