Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that these descriptions are only for further illustrating the features and advantages of the present utility model, and are not limiting the patent claims of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model will be further described with reference to the drawings and preferred embodiments.

Example 1

Referring to fig. 1 and 2, the hinge assembly with a limiting function according to this embodiment includes a hinge pivot 1, a first hinge plate 2 and a second hinge plate 3 are rotatably connected to the hinge pivot 1, one end of the first hinge plate 2 facing the second hinge plate is provided with a first notch 4, one end of the second hinge plate 3 facing the first hinge plate is provided with a second notch 5, the second notch 5 and the first notch 4 are internally provided with a limiting post 6 which is arranged on the hinge pivot and is in a regular hexagonal prism shape, one end of the first notch 4 is abutted against one side surface of the limiting post, the other end of the first notch is connected with a fixed locking plate 7 on the first hinge plate, and one end of the second notch 5 is abutted against one side surface of the limiting post, and the other end of the second hinge plate is connected with an elastic locking plate 8.

Further, two sides of the elastic locking piece 8 are respectively provided with a crumple groove 9 formed on the second hinge plate 3.

Further, the hinge pivot 1 includes a pivot main body 11 and a limiting post 6 connected in series to the pivot main body 11, the pivot main body 11 is provided with a clamp spring groove 12, and an outer clamp spring 13 is embedded in the clamp spring groove 12.

Further, a transition portion 14 is provided between the pivot main body 11 and the limiting post 6, and the transition portion 14, the pivot main body 11 and the limiting post 6 are in an integral structure.

In this embodiment, the second hinge plate 3 is rotatable relative to the hinge pivot 1 and the first hinge plate 2, in connection with the hinge pivot 1. During the rotation of the second hinge plate 3 relative to the hinge pivot 1, the limiting post 6 on the hinge pivot 1 is propped against by the fixed locking plate 7, so that the second hinge plate 3 rotates relatively, the elastic locking plate 8 deforms first, and then one side surface of the limiting post 6 is changed into the other side surface, so that the second hinge plate 3 is locked at one position every 60 degrees.

Wherein, through the seting up of the crumple groove 9, make the elastic locking plate 8 deformation more obvious, cause the rotation second hinge board 3 more laborsaving.
