Referring to FIG. 3 at the same time, the abutting portion 11 is substantially cylindrical and has a first end surface 111 and a second end surface 113 opposite to each other.

The shaft 13 extends perpendicularly from the first end surface 111 of the abutting portion 11 and includes a limiting portion 131, a guiding portion 133 and a threaded portion 135. The limiting portion 131 is disposed at one end of the shaft 13 adjacent to the abutting portion 11 and includes a guiding portion 1311 and a limiting portion 1313 communicating with the guiding portion 1311. The guiding portion 1311 is an annular groove around the circumference of the shaft 13. The limiting portion 1313 is a groove extending from the guiding portion 1311 to the first end surface 111 of the abutting portion 11. In this embodiment, the limiting portion 1313 has two It is symmetrically disposed on the circumferential surface of the shaft 13. The guiding portion 133 is a two groove extending axially parallel to the shaft 13 and symmetrically disposed on the shaft 13. The threaded portion 135 is disposed on the shaft 13 away from one end of the abutting portion 11.

The engaging rod 15 is a rod body that extends perpendicularly from the second end surface 113 of the abutting portion 11 and has a non-circular cross section.

Referring to FIG. 1 and FIG. 4 simultaneously, the locking member 20 has a substantially cylindrical structure, and the outer wall is formed with two opposite positioning faces 21, and the inner wall has opposite locking portions 23 protruding therefrom. The locking member 20 can be sleeved on the shaft 13 of the rotating shaft 10 , and the locking portion 23 can slide into the limiting portion 131 via the guiding portion 133 of the shaft 13 .

Referring to FIG. 1 , the spacer 30 has a substantially cylindrical structure, and the outer wall is formed with two opposite positioning faces 31 , and the spacer 30 can be sleeved on the shaft 13 of the rotating shaft 10 .

The elastic member 40 is a spring piece that can be sleeved on the shaft 13 of the rotating shaft 10. The number of the elastic pieces can be one or plural. In the embodiment, the elastic piece has two.

The first bracket 50 includes a body 51 and a fixing plate 53 extending from the body 51. A non-circular receiving hole 511 for receiving the locking member 20 and the spacer 30 is formed through the main body 51. The positioning cut surface 21 of the locking member 20 and the positioning cut surface 31 of the spacer 30 can prevent the locking member 20 and the spacer 30 from rotating relative to the first bracket 50. A fixing hole 531 is defined in the fixing plate 53 for fixing the first bracket 50 to an electronic device (not shown).

The second bracket 60 has a connecting piece 61. The connecting piece 61 has a non-circular connecting hole 611 extending therethrough, and the connecting hole 611 is provided for the connecting rod 15 of the rotating shaft 10 to pass through. The connecting rod 15 has an interference fit with the connecting hole 611 to fix the rotating shaft 10 to the second bracket 60.

The fastener 70 is engageable with the threaded portion 135 of the rotating shaft 10 to fix the components that are sleeved on the shaft 13 of the rotating shaft 10. In this embodiment, the fastener 70 is a fastening nut.

Referring to FIG. 1 to FIG. 3 , when the hinge structure is assembled, the locking component 20 and the spacer 30 are first sleeved on the shaft 13 of the rotating shaft 10 , wherein the locking portion 23 of the locking component 20 is received in the shaft 13 . Inside the guide portion 133. Then, the first bracket 50 is sleeved on the locking member 20 and the spacer 30, and the elastic member 40 is sleeved on the shaft 13 to be in contact with the spacer 30. The components are then secured to the shaft 13 by nesting the fastener 70 over the threaded portion 135 of the shaft 13, at which point the resilient member 40 is compressed and abuts against the spacer 30. The second bracket 60 can be directly sleeved on the connecting rod 15 of the rotating shaft 10.

Referring to FIG. 4 together, the first bracket 50 is rotated, and the pressure of the elastic member 40 against the spacer 30 can cause the spacer 30 to move axially on the shaft 13 and push the locking member 20 to move along the guiding portion 133 of the shaft 13. Until the locking portion 23 of the locking member 20 moves to the guiding portion 1311 of the limiting portion 131 of the shaft 13 . The first bracket 50 continues to rotate, and the locking portion 23 slides along the guiding portion 1311 of the limiting portion 131. When the locking portion 23 slides to the binding portion 1313 of the limiting portion 131 and the guiding portion 1311, the locking portion 23 automatically Sliding into the limit segment 1313, the self-locking of the hinge structure is achieved.

The hinge structure provided by the embodiment of the present invention cooperates with the locking portion 23 of the locking member 20 to achieve self-locking, which saves components and reduces manufacturing costs. In addition, the locking component 20 is received in the first bracket 50, so the occupied space is small.
