Patent ID: 8245355

Claim:
A hinge assembly, comprising: a pivot shaft; a fixing leaf rotatably connected to the pivot shaft; a restricting member rotatably sleeved on the pivot shaft and abutting the fixing leaf, the restricting member defining a positioning groove at an end surface thereon; a deformable member non-rotatably sleeved on the pivot shaft, comprising a base plate and two protrusions extending substantially perpendicularly from an end surface of the base plate away from the restricting member, and the base plate of the deformable member defining a latching groove at another end surface thereon adjacent to the restricting member; a limiting block partially received in the positioning groove and connected to the deformable member, wherein the limiting block comprises a resisting portion, a latching portion, and a position portion extending from opposites ends of the resisting portion; the positioning portion is received in the positioning groove, the latching portion is latched in the latching groove, and the resisting portion resists the base plate of the deformable member; when the pivot shaft is rotated, the limiting block slides out of the positioning groove to press the base plate of the deformable member such that the deformable member becomes elastically deformed and applies an axial force effecting on the restricting member; and a fastening member fixed on an end of the pivot shaft to prevent the deformable member from moving along the pivot shaft.
