Abstract

The present utility model discloses a semi-automatic rotating and sliding hinge, arranged between a master and a covering body of an electronic device, which compromises an insert-in connecting axle with a rotating shaft, on the brim of which are arranged with two parallel sustaining surfaces; a joining shaft of the canister body, of which a hole is formed on the center for an insertion-joining and arranged with a longitudinally slot through a insertion-joining hole. The hole is provided for the joining of the rotation shaft. In addition, a plurality of annular elastic flakes are sheathed outside the canister body. The flake has location block protruding inwards and forms a pressing level. The location block is used for clamping in a slot, while the pressing level is used for the clamping towards the sustaining surface of the rotation shaft. After the shaft rotates relative to the canister body, elastic flakes will expand and compress after resist from the rotation shaft. By elastic compression of the flake, the rotation shaft will turn and displace by sliding relative to the canister body.

Description

Pivot with the sliding position of semi-automatic rotation

Technical field
