Detailed Implementation

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Figures 1 to 6 illustrate a damping hinge according to an embodiment, comprising a first mounting base 1, a second mounting base 2, a clamping shaft 3, and a clamping nut 4. A first sleeve 11 and a third sleeve 12 are formed on the first mounting base 1, and a second sleeve 21 and a fourth sleeve 22 are formed on the second mounting base 2. The first sleeve 11, fourth sleeve 22, third sleeve 12, and second sleeve 21 are arranged alternately along a straight line. The first sleeve 11 and fourth sleeve 22, the fourth sleeve 22 and third sleeve 12, and the third sleeve 21 are positioned alternately. Friction pads 5 are provided between the first sleeve 11 and the second sleeve 21. The clamping shaft 3 is formed along its axis by a clamping head 31, a shaft 32 and a stud 33. The stud 33 of the clamping shaft 3 passes through the first sleeve 11, the fourth sleeve 22, the third sleeve 12 and the second sleeve 21 in sequence and is threadedly connected to the clamping nut 4. The clamping head 31 of the clamping shaft 3 and the clamping nut 4 together clamp the first mounting seat 1 and the second mounting seat 2, so that a damping force is generated between the first mounting seat 1 and the second mounting seat 2.

[0024] The working principle of this embodiment is as follows:

[0025] In use, by adjusting the tightness between the stud part 33 of the clamping shaft 3 and the clamping nut 4, the clamping force of the first mounting seat 1 and the second mounting seat 2 on the friction pad 5 can be adjusted, thereby adjusting the friction damping force between the first mounting seat 1 and the second mounting seat 2. This design makes it convenient to adjust the damping force of this damping hinge.

[0026] As shown in Figures 1 and 4, a mounting groove 111 is formed on one end face of the first sleeve 11. The bottom of the mounting groove 111 is connected to the other end face of the first sleeve 11 through a first pivot hole. The shaft portion 32 of the clamping pivot 3 passes through the first pivot hole, and the clamping head 31 of the clamping pivot 3 is embedded in the mounting groove 111 and abuts against the bottom of the mounting groove 111. This design prevents the clamping head 31 of the clamping pivot 3 from being exposed on the surface of the damping hinge, preventing the clamping pivot 3 from being accidentally operated during use and changing the damping force between the first mounting base 1 and the second mounting base 2, thereby improving the stability of the damping hinge.

[0027] As shown in Figure 4, a lubricating pad 6 is provided between the clamping head 31 of the clamping shaft 3 and the first mounting base 1. By providing the lubricating pad 6, the friction between the clamping head 31 of the clamping shaft 3 and the first mounting base 1 can be reduced. During the relative rotation of the first mounting base 1 and the second mounting base 2, this design can prevent the clamping shaft 3 from being driven to rotate by the first mounting base 1, thereby changing the magnitude of the damping force between the first mounting base 1 and the second mounting base 2 and improving the stability of this damping hinge.

[0028] As shown in Figures 2, 4, and 5, a locking groove 211 is formed on one end face of the second sleeve 21. The locking groove 211 is a hexagonal groove, and the bottom of the locking groove 211 is connected to the other end face of the second sleeve 21 through a second rotating shaft hole. The clamping rotating shaft 3 passes through the second rotating shaft hole. The clamping nut 4 is embedded in the locking groove 211 and abuts against the bottom of the locking groove 211. The clamping nut 4 is locked and positioned with the locking groove 211 in the circumferential direction. With this design, on the one hand, the clamping nut 4 is prevented from being exposed on the surface of the damping hinge, preventing the clamping nut 4 from being accidentally operated during use and changing the damping force between the first mounting base 1 and the second mounting base 2, thus improving the stability of the damping hinge. On the other hand, by locking and positioning the clamping nut 4 with the locking groove 211 in the circumferential direction, the clamping nut 4 does not need to be manually positioned when adjusting the damping force. The damping force can be adjusted simply by rotating the clamping rotating shaft 3, making the operation more convenient.

[0029] As shown in Figures 2, 4, 5, and 6, the clamping nut 4 includes a nut body 41 and a friction spring 42. The nut body 41 is threadedly connected to the stud portion 33 of the clamping shaft 3. The nut body 41 includes a locking portion 411 and a boss portion 412. The outer contour of the cross-section of the locking portion 411 is hexagonal, and the boss portion 412 is located on the side of the locking portion 411 closest to the opening of the locking groove 211. The friction spring 42 is disposed on the boss portion 412 of the nut body 41, and the friction spring 42 abuts against the thread of the stud portion 33 of the clamping shaft 3 and applies an elastic force. Through the structure of the friction spring 42, the friction force between the clamping nut 4 and the stud portion 33 of the clamping shaft 3 is increased, giving the clamping nut 4 good anti-loosening performance. In a vibration environment, the clamping nut 4 is less likely to rotate and change the magnitude of the damping force between the first mounting seat 1 and the second mounting seat 2, thereby improving the stability of this damping hinge.

[0030] As shown in Figures 1 and 4, an adjustment groove 311 is formed on the end face of the clamping head 31 of the clamping shaft 3. In use, an external wrench drives the clamping shaft 3 to rotate through the adjustment groove 311. In this embodiment, the adjustment groove 311 is a hexagonal groove. In use, the user can drive the clamping shaft 3 to rotate by inserting a hexagonal wrench into the adjustment groove 311 of the clamping shaft 3, thereby adjusting the damping force between the first mounting base 1 and the second mounting base 2. The operation is relatively simple.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
