Abstract

An industrial computer hinge assembly includes a bolt having a head and an extension, a first positioning ring with a first hook, a second positioning ring with a second hook, multiple leaf springs and an assembly device having an extension hole and a first fixing hole defined in a main board casing to correspond to the extension of the bolt and the first hook respectively and a hole and a second fixing hole defined in a screen casing to correspond to the extension and the second hook respectively. After the extension combines with the nut, engagement between the first positioning ring and the second positioning ring provides friction force to support the screen casing relative to the main board casing.

Claims

1. An industrial computer hinge assembly comprising:

a bolt having a head and an extension extending from a side face of the head and a threading formed on the extension;

a first positioning ring with a first hook formed on an outer periphery of the first positioning ring;

a second positioning ring with a second hook formed on an outer periphery of the second positioning ring;

multiple leaf springs each with a through hole corresponding to the extension; and

an assembly device comprising an extension hole and a first fixing hole defined in a main board casing to correspond to the extension of the bolt and the first hook respectively and a hole and a second fixing hole defined in a screen casing to correspond to the extension and the second hook respectively,

wherein the bolt has a flat portion formed on two opposite sides of the bolt and the threading extending from a free end of the extension,

wherein at least one through hole of one of the leaf springs is so configured that after the extension extends through the at least one through hole of the leaf spring, the extension is immovable relative to the one of the first leaf springs,

whereby after the extension extends through the first positioning ring, the second positioning ring and the leaf springs to combine with the nut, engagement between the first positioning ring and the second positioning ring provides friction force to support the screen casing relative to the main board casing.

2. The industrial computer hinge assembly as claimed in claim 1, wherein the threading has a length larger than a thickness of the nut together with a thickness of the second leaf springs.
