Abstract

The invention relates to a computer positioning rotation shaft arranged between a computer motherboard and an LCD screen panel. The rotation shaft comprises a core shaft, a movable support connected to the LCD screen panel, and a fixed support connected to the computer motherboard. A central through hole used for threading electric cables is provided on the core shaft. One end of the core shaft is fixed with the fixed support, and the other end of the core shaft sequentially penetrate and is firmly fitted with a pair of opposite and juxtaposed hollow rolls. The pair of hollow rolls is formed by roll holes with end edges, wherein the roll holes are formed by a rigid material. Two end edges of the hollow rolls are integrated with the movable support. Corresponding to the gap between the pair of the hollow rolls, an annular step used for preventing axial sliding of the pair of the rolls and the core shaft is provided at a central position of the core shaft. With the rotation shaft provided by the invention, computer rotation positioning can be ensured, and the electric cables can conveniently penetrate the core shaft. Therefore, laptop cabling convenience and safety are ensured.

Description

Computer-positioning spindle

Technical field

The invention belongs to the improvement of computer-positioning spindle, particularly a kind of for the computer-positioning spindle between liquid crystal screen on notebook computer and host board.

Background technique

Between traditional notebook computer liquid crystal plate and host board, the space is larger, facilitates line, but along with other electronic products are more and more lightening, the frivolous epoch of notebook also arrive.But, frivolously meaning dwindling of space, the space between liquid crystal screen and host board is also just more and more less so thereupon, and this has just caused the difficulty of crossing line.

Summary of the invention

In order to make up above deficiency, the invention provides a kind of computer-positioning spindle, both guaranteed the rotating position of computer rotation shaft, facilitate simultaneously elastic cable paper to pass axle, so can be notebook computer and cross the convenience of line and provide safeguard safely.

Technological scheme of the present invention is such realization: a kind of computer-positioning spindle, be installed between computer motherboard and liquid crystal screen, comprise axle, connect the travel(l)ing rest of liquid crystal screen and the fixed support that connects computer motherboard, this axle is provided with the central through bore of being convenient to pass elastic cable paper, and this axle one end and this fixed support are fixed, and this axle the other end passes successively and a pair of volume circle that oppositely is arranged side by side of close-fitting, this is to rolling up the volume circular hole with end limit of circle for being formed by rigid, and this holds the limit to be fixed in simultaneously this travel(l)ing rest to two of rolling up on circle.

As a further improvement on the present invention, this is one-body molded to rolling up round two end limits and this travel(l)ing rest.

As a further improvement on the present invention, to should be to rolling up the gap between circle, this axle intermediate portion be provided with and can prevents that this is to rolling up circle and axle ring-shaped step in axial sliding.

As a further improvement on the present invention, the central through bore two ends on this axle form respectively all chamferings of ring.

As a further improvement on the present invention, this forms respectively chamfering to the volume circular hole both sides of rolling up on circle.

As a further improvement on the present invention, the ring-shaped step both sides on this axle form respectively the ring-type chamfering.

As a further improvement on the present invention, this axle can be controlled relative this stopper protrusion and the link stopper to rolling up round rotation angle of this axle with this to rolling up to be respectively equipped with on circle.

Useful technique effect of the present invention is: this axle one end and this fixed support are fixed, and the other end passes successively and a pair of volume circle that oppositely is arranged side by side of close-fitting, this is to rolling up the volume circular hole with end limit of circle for being formed by rigid, this to roll up the circle on two the end limit be fixed in simultaneously this travel(l)ing rest, interfere with the close-fitting of axle rolling up circle by this, produce torsion, this axle and this travel(l)ing rest have been realized locating rotation, this axle is provided with the central through bore of being convenient to pass elastic cable paper simultaneously, has reduced the space of notebook computer.

Fig. 1 is assembling schematic diagram of the present invention;

Fig. 2 is structural representation of the present invention;

Fig. 3 is the structural representation of the circle of volume described in the present invention;

Fig. 4 is the structural representation of axle described in the present invention.

Contrast above accompanying drawing, be supplemented as follows explanation:

Embodiment:

In conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4, below be described in detail:

a kind of computer-positioning spindle, be installed between computer motherboard and liquid crystal screen, comprise axle 1, connect the travel(l)ing rest 4 of liquid crystal screen and the fixed support 3 that connects computer motherboard, this axle 1 is provided with the central through bore 11 of being convenient to pass elastic cable paper, and this axle one end and this fixed support 3 are fixing, and this axle the other end passes successively and a pair of volume circle that oppositely is arranged side by side of close-fitting, in the present embodiment, define this and be respectively first volume circle 21 and volume Two circle 22 to rolling up circle, this is to rolling up the volume circular hole with end limit of circle for being formed by rigid, this to roll up the circle on two the end limit and this travel(l)ing rest 4 one-body molded.

To should to roll up the circle between the gap, this axle 1 intermediate portion is provided with and can prevents that this is to rolling up circle and axle ring-shaped step 12 in axial sliding, can prevent that like this in rotation process, this axle 1 gets loose with travel(l)ing

rest

4, and 12 both sides of the ring-shaped step on this axle 1 form the ring portion chamfering, can facilitate this axle to be assembled into smoothly this to rolling up in the volume circular hole on circle.

For convenience of notebook computer elastic cable paper (comprising database line and connection) wiring, be designed to central through bore 11 on this axle 1 is axial, can facilitate the various power supplys of notebook or datawire therefrom to pass, and for preventing in this axle rotation process power supply or datawire damage, central through bore 11 two ends on this axle form respectively all chamferings 111 of ring.

For convenience of moulding and assembling, this has respectively chamfering 23 to the volume circular hole both sides of rolling up on circle.

This axle 1 can be controlled relative this stopper protrusion 13 and the link stopper 24 to rolling up round rotation angle of this axle with this to rolling up to be respectively equipped with on circle.

When opening or closing liquid crystal screen, liquid crystal screen drives travel(l)ing rest 4 and rotates, and produces torsion by integrated this of this axle 1 and travel(l)ing rest 4 to rolling up round interference.
