The utility model discloses a computer positioning rotating shaft, which is arranged between a computer host board and a liquid crystal screen board and comprises a core shaft, a movable bracket connected with the liquid crystal screen board and a fixed bracket connected with the computer host board, wherein the core shaft is provided with a central through hole through which a cable penetrates, one end of the core shaft is fixed with the fixed bracket, and the other end of the core shaft sequentially penetrates through and is tightly matched with a pair of rolling circles arranged side by side; the pair of rolling circles are made of rigid material and provided with rolling circle holes with end edges; the two end edges of the pair of rolling circles and the movable bracket are integrally formed; and corresponding to the clearance between the pair of rolling circles, the middle part of the core shaft is provided with an annular step capable of preventing axial sliding of the pair of rolling circles and the core shaft. Rotating positioning of the computer rotating shaft is ensured, the cable conveniently penetrates through the core shaft, and guarantee can be provided for wiring convenience and safety of a notebook computer.

Description

The computer positioning rotating shaft

Technical field

The utility model belongs to the improvement of computer positioning rotating shaft, particularly a kind ofly is used for the computer positioning rotating shaft between the liquid crystal screen and motherboard on the notebook computer.

Background technology

The space is bigger between traditional notebook computer liquid crystal plate and the motherboard, makes things convenient for 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 the motherboard is also just more and more littler so thereupon, and this has just caused the difficulty of crossing line.

Summary of the invention

In order to remedy above deficiency, the utility model provides a kind of computer positioning rotating shaft, has both guaranteed the rotational positioning of computer rotation shaft, makes things convenient for cable to pass axle simultaneously, so can be convenience and safe providing safeguard that notebook computer is crossed line.

The technical scheme of the utility model is such realization: a kind of computer positioning rotating shaft; Be installed between computer motherboard and the 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 hole of being convenient to pass cable, and this axle one end and this fixed support fix, and this axle 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 have volume circular hole of holding limit of circle for being formed by the rigidity material, and this is fixed in this travel(l)ing rest simultaneously to two end limits of rolling up on the circle.

As the further improvement of the utility model, this is one-body molded to rolling up round two end limits and this travel(l)ing rest.

As the further improvement of the utility model, to should be to rolling up the gap between the circle, this axle middle part be provided with and can prevents that this is to rolling up circle and axle ring-shaped step in axial sliding.

As the further improvement of the utility model, the central through hole two ends on this axle form all chamferings of ring respectively.

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

As the further improvement of the utility model, the ring-shaped step both sides on this axle form the ring-type chamfering respectively.

As the further improvement of the utility model, this axle and this to roll up be respectively equipped with on the circle can control this axle relatively this to rolling up the spacing protuberance and the block of round rotational angle.

The useful technique effect of the utility model 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 have volume circular hole of holding limit of circle for being formed by the rigidity material, and this is fixed in this travel(l)ing rest simultaneously to two end limits of rolling up on the circle, interferes with the close-fitting of axle rolling up circle through this; Produce torsion; This axle and this travel(l)ing rest have been realized the location rotation, and this axle is provided with the central through hole of being convenient to pass cable simultaneously, has reduced the space of notebook computer.

Embodiment:

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

A kind of computer positioning rotating shaft; Be installed between computer motherboard and the 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 hole 11 of being convenient to pass cable; And this axle one end and this fixed support 3 are fixing; And this axle other end passes successively and a pair of volume circle that oppositely is arranged side by side of close-fitting, in the present embodiment, defines this and is respectively first volume circle 21 and second volume circle 22 to rolling up circle; This has the volume circular hole of hold limit to rolling up circle for what is formed by the rigidity material, and this is one-body molded to two end limits and this travel(l)ing rest 4 rolled up on justifying.

To should to roll up the circle between the gap; This axle 1 middle part 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 this axle 1 gets loose with travel(l)ing rest 4 in the rotation process; And ring-shaped step 12 both sides on this axle 1 form the ring portion chamfering, can make things convenient for this axle to be assembled into this smoothly to rolling up in the volume circular hole on the circle.

For making things convenient for notebook computer cable (comprising database line and connection) wiring; This axle 1 is designed to central through hole 11 on axially; Can make things convenient for various power supplys of notebook or data line therefrom to pass; And for preventing in this axle rotation process power supply or data line to be damaged, central through hole 11 two ends on this axle form all chamferings 111 of ring respectively.

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

This axle 1 can be controlled this axle this spacing protuberance 13 and block 24 to rolling up round rotational angle relatively with this to rolling up to be respectively equipped with on the circle.

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