[0014] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following describes the preferred implementation schemes of the present utility model in combination with specific embodiments. However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] The present utility model will be further described below in combination with the drawings and preferred embodiments.

[0016] Embodiment 1

[0017] Refer to Figures 1 to 3 As shown, a damping hinge involved in this embodiment includes a stud, which is composed of a first stud portion 1, a second stud portion 2, and a stud shoulder 3 connected between the first stud portion and the second stud portion. A first external hexagonal nut 4 is threadedly connected to the first stud portion 1. An active connection portion 5 extending radially is connected to the side surface of the first external hexagonal nut 4. A fixed connection portion 6 is provided on the second stud portion 2. A second external hexagonal nut 7 is threadedly connected to the second stud portion 2;

[0018] It further includes an L-shaped connecting member 8, which is composed of a connecting bottom plate 81 and a connecting side plate 82. A process hole 83 is formed in the connecting bottom plate 81. The second stud portion 2 penetrates into the process hole 83. The connecting bottom plate 81 is arranged between the stud shoulder 3 and the second external hexagonal nut 7 and is clamped. The connecting side plates 82 respectively abut against the first external hexagonal nut 4 and the stud shoulder 3.

[0019] Further, connecting holes 9 are respectively formed in the movable connecting portion 5 and the fixed connecting portion 6.

[0020] Further, the movable connecting portion 5 and the first external hexagonal nut 4 are fixed by welding.

[0021] In this embodiment, the second external hexagonal nut 7 screwed on the second stud portion 2 is paired with the stud shoulder 3 and used for locking and fixing the L-shaped connecting member 8. One side surface of the first external hexagonal nut 4 in the reset state is close to and parallel to the connecting side plate 82. When the movable connecting portion 5 drives the first external hexagonal nut 4 to rotate by 60°, 120° or 180°, the first external hexagonal nut 4 will push the elastic connecting side plate 82 outwards to deform it. After the position of the first external hexagonal nut 4 is adjusted, the connecting side plate 82 deforms and resets until one side surface of the first external hexagonal nut 4 returns to the state of being close to and parallel to the connecting side plate 82.

[0022] Among them, since the movable connecting portion 5 drives the first external hexagonal nut 4 to rotate, and the multiple rotation circumferential angles are not greater than 360°, the rotational relationship between the first stud portion 1 and the first external hexagonal nut 4 can be realized by means of threaded connection; it also has the characteristic of facilitating the disassembly and assembly between components.

[0023] Embodiment 2

[0024] See Figures 1 to 3 As shown, a damping hinge involved in this embodiment is further provided on the basis of Embodiment 1, such that one side of the stud shoulder 3 facing the connecting side plate 82 has a first notch groove 31, and the connecting side plate 82 is arranged in the first notch groove 31.

[0025] In this embodiment, through the provision of the first notch groove 31, it is used for the installation and positioning of the connecting side plate 82.

[0026] Embodiment 3

[0027] See Figures 1 to 3 As shown, a damping hinge involved in this embodiment is further provided on the basis of Embodiments 1 and 2, such that two second notch grooves 84 arranged symmetrically left and right are provided on the connecting side plate 82, and the second notch grooves 84 are close to the connecting bottom plate 81.

[0028] In this embodiment, through the provision of the second notch grooves 84, the effect of preventing stress concentration is achieved, and good elasticity is imparted to the connecting side plate 82.

[0029] The damping hinge involved in the present utility model is provided with an elastic connecting side plate on one side of the first external hexagonal nut that rotates actively, which abuts against the first external hexagonal nut. After the first external hexagonal nut is rotated by 60° each time, the position of the first external hexagonal nut can be defined by the connecting side plate that abuts against it, achieving an arbitrary stop positioning effect. Moreover, the overall installation is convenient, the function is perfect, and the practicability is strong.

[0030] Unless otherwise clearly specified and defined, in the present utility model, if there are terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated is based on the actual orientation or positional relationship shown. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms used to describe the orientation or positional relationship in the present utility model are only for exemplary illustration and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood in combination with the embodiments and according to the specific circumstances.

[0031] Unless otherwise clearly specified and defined, in the present utility model, if there are terms such as "set", "connected" and "connected", they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0032] The above has described in detail the preferred specific embodiments of the present utility model. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present utility model without creative labor.
