[0002] Hidden hinges are mechanical devices used to connect two solid objects and allow them to rotate relative to each other. Hidden hinges can be composed of movable components or foldable materials. Hidden hinges are mostly installed on cabinets. They are mainly divided into stainless steel hinges and iron hinges according to the material. Hidden hinges are not only used on doors, windows and cabinets, but also on some household items that require angle adjustment and positioning, such as computer stands. In order to ensure the stability after the angle adjustment, a positioning protrusion structure is usually used in conjunction with the hidden hinge so that the hinge structure can be stabilized in the current rotation position.

[0003] When the existing hidden hinge positioning protrusion is used in conjunction with a hidden hinge, the positioning strength is usually fixed, and the positioning strength cannot be adjusted according to the load requirements of the hidden hinge. As a result, when the hidden hinge positioning protrusion is loaded with a large load and shakes, positioning failure is prone to occur, which greatly affects the positioning tightness of the hidden hinge positioning protrusion and reduces the use effect of the hidden hinge positioning protrusion. Therefore, a technician in this field provides a hidden hinge positioning protrusion to solve the problems raised in the above background technology. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Refer to the figure Figure 1-4The utility model discloses a hidden hinge positioning protrusion, comprising two mounting plates 1, wherein the right side of one mounting plate 1 is fixedly connected to two supporting blocks 2, and the left side of the other mounting plate 1 is fixedly connected to a rotating block 3, and the interior of each mounting plate 1 is threadedly connected to two mounting bolts 13, and one end of each mounting bolt 13 close to the mounting plate 1 penetrates the mounting plate 1 and extends to the back side of the mounting plate 1, and the mounting bolts 13 can fix the mounting plate 1 in the working position, so that the device can be quickly installed in the required position.

[0023] The two supporting blocks 2 are fixedly connected with a rotating column 4 on one side close to each other. The rotating column 4 is rotatably connected to the inside of the rotating block 3. The outer surface of the rotating column 4 is clamped with a limiting ring 14. The bottom surface of the limiting ring 14 is in contact with the upper surface of the rotating block 3. The limiting ring 14 can limit the position of the rotating block 3 so that the rotating block 3 will not slide up and down on the rotating column 4 at will, thereby improving the stability of the rotating block 3 during use.

[0024] Two compression springs 5 ​​are fixedly connected to the upper surface of the rotating block 3, and the top ends of the two compression springs 5 ​​are fixedly connected to the lower toothed disk 6. A limiting column 15 is arranged inside each compression spring 5, and the top end of each limiting column 15 is fixedly connected to the bottom surface of the lower toothed disk 6. Each limiting column 15 is slidably connected to the inside of the rotating block 3. The limiting column 15 can increase the stability of the compression spring 5 without affecting the extension and contraction of the compression spring 5, so that the compression spring 5 is not prone to excessive bending and deformation when under pressure.

[0025] The upper surface of the lower gear plate 6 is meshedly connected with the upper gear plate 7, and the inner wall of the lower gear plate 6 and the inner wall of the upper gear plate 7 are in contact with the outer surface of the rotating column 4. Two sliding columns 8 are slidably connected to the inside of one of the support blocks 2, and the bottom end of each sliding column 8 is fixedly connected to the upper surface of the upper gear plate 7. Two adjusting bolts 9 are connected to the internal thread of one of the support blocks 2, and the bottom end of each adjusting bolt 9 is in contact with the top of the sliding column 8. Two sealing rings 16 are fixedly connected to the upper surface of one of the support blocks 2, and the inner wall of each sealing ring 16 is in contact with the outer surface of the adjusting bolt 9. The sealing ring 16 can close the gap between the support block 2 and the adjusting bolt 9, making it difficult for dust and impurities to enter the gap, thereby ensuring the smooth rotation of the adjusting bolt 9.

[0026] A rotating table 10 is arranged above the other supporting block 2, and the inner wall of the rotating table 10 is fixedly connected to the outer surface of the rotating column 4. A knob 17 is fixedly connected to the top of each adjusting bolt 9, and a positioning hole 18 is opened on the front of each mounting plate 1. The knob 17 can facilitate the user to manually rotate the adjusting bolt 9, thereby increasing the convenience of manual operation of the adjusting bolt 9. The positioning hole 18 can locate the position of the mounting plate 1, thereby increasing the installation accuracy of the mounting plate 1.

[0027] A plurality of ball bearings 11 are slidably connected inside the rotating table 10, an annular groove 12 is provided on the bottom surface of the rotating block 3, and each ball bearing 11 is slidably connected inside the annular groove 12. Two support columns 19 are fixedly connected to the upper surface of the other support block 2, and the top of each support column 19 is fixedly connected to the bottom surface of the rotating table 10. The support columns 19 can reinforce the rotating table 10 and increase the bearing capacity of the rotating table 10.

[0028] The working principle of the utility model is as follows: when in use, firstly, the mounting plate 1 is fixed in the required position by the mounting bolt 13 in cooperation with the positioning hole 18. When the positioning strength of the hidden hinge positioning protrusion needs to be adjusted after the angle adjustment, the adjusting bolt 9 is rotated to push the sliding column 8 to move downward. When the sliding column 8 moves downward, the upper toothed disc 7 and the lower toothed disc 6 can be pushed downward, thereby forcing the compression spring 5 to contract and accumulate pressure. At this time, the pressure accumulated by the compression spring 5 can make the upper toothed disc 7 and the lower toothed disc 6 mesh more tightly, and then the right mounting plate 1 is rotated to cooperate with the rotating block 3 to adjust the opening and closing angle based on the left mounting plate 1, forcing the upper toothed disc 7 and the lower toothed disc 6 to mesh more tightly. It is more laborious when the toothed disc 6 is forced to disengage and re-engage, thereby improving the load-bearing capacity of the hidden hinge positioning protrusion after positioning, allowing the positioning strength of the hidden hinge positioning protrusion to be quickly adjusted as needed, greatly improving the positioning tightness and adaptability of the hidden hinge positioning protrusion. Finally, by rotating the ball 11 inside the rotating table 10 and the annular groove 12 to cooperate with the fixed connection relationship between the rotating table 10 and the rotating column 4, the vertical bearing capacity of the rotating block 3 can be provided without affecting the smooth rotation of the rotating block 3, and the wear of the rotating block 3 on the rotating column 4 can be reduced, thereby ensuring the service life and stability of the hidden hinge positioning protrusion.
