Rotary shaft wire passage structure

Abstract

A rotary shaft wire passage structure includes a pivot pin and a pivot seat respectively fixedly connected with a pivotal rotary member and a relative pivotal rotary member. The pivot pin has a pivoted section and an annular raised section disposed at one end thereof. The pivoted section is formed with an axial through hole in full communication with outer side via a split. The pivot seat has a shaft hole in which the pivoted section is fitted. One side of the shaft hole is formed with a fissure in communication with the outer side. The fissure is adjustable to a position where the fissure is aligned with the split for placing a wire into the through hole. When the relative pivotal rotary member is pivotally rotated to a working position by a certain angle, the fissure is misaligned from the split to prevent the wire from slipping out.

Description

REFERENCE TO RELATED APPLICATION[0001]This Application is being filed as a Continuation Application of Serial #13 / 552,811, filed 19 Jul. 2012, currently pending.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to an improved rotary shaft wire passage structure, and more particularly to a rotary shaft structure, which is easy to assemble and able to provide full protection for the wire without affecting operation of the product.[0004]2. Description of the Related Art[0005]A conventional rotary shaft wire passage structure generally includes a rotary shaft pivotally connected between a pivotal rotary member (such as a screen) and a relative pivotal rotary member (such as a main body). The rotary shaft is formed with a central through hole having two openings at two ends of the rotary shaft respectively. A wire can be conducted from the relative pivotal rotary member (the main body) through the rotary shaft into the pivotal rotary ...

AI Technical Summary

Benefits of technology

The present invention provides an improved rotary shaft wire passage structure that is easier to assemble and has better product quality. The manufacturing process is also simplified, with the need for transfer of the hollow rotary shaft to a wiring workshop being eliminated, saving time and increasing efficiency. Additionally, the wire is fully protected to prolong its lifespan.

Problems solved by technology

Therefore, the relative pivotal rotary member (the main body) and the pivotal rotary member (the screen) often fail to provide sufficient assembling space on two sides of the rotary shaft.

This makes it difficult to conduct the wire through the through hole.

1. It is necessary to first transfer the rotary shaft to the wiring workshop to wire the rotary shaft. This leads to increase of processing time and cost. Moreover, the semi-product of the rotary shaft is likely to damage during the transfer. As a result, the ratio of defective products is increased.

2. The processing procedure of the semi-product of the rotary shaft leads to increase of the number of the manufacturing steps. Furthermore, the rotary shaft is relatively inconvenient to assemble. As a result, the production efficiency is lower and the cost is increased.Patent application U.S. Pat. No. 6,671,929 B1 “Hinge for a Notebook Computer” discloses that a pintle 10 and a resilient sleeve 20. The sleeve 20 has a trough hole, an elongate opening 21 and protrusions 22. Also, a barrel 30(or 40) is formed with an axial hole and a lug 31 or 41. In this embodiment, the structure of the pintle 10 cannot reach the goal of installing the wire.
