Abstract

The utility model discloses a disk inclination adjusting structure of a compact disk player, which comprises an optical head base, an optical head, an auxiliary guide rod, a main guide rod, a spindle motor and a motor support for fixing the spindle motor. The motor support is mounted on the optical head base, the front surface of the motor support is provided with a cylindrical shaft for fixing the spindle motor, a hole for positioning an adjusting screw and a positioning part for positioning an elastic component, and an adjusting spring and the adjusting screw are arranged under one end of the main guide rod or auxiliary guide rod. The disk inclination adjusting structure of a compact disk player can not only adjust inclination of disks of the compact disk player accurately, but also reduce the number of the parts and reduce cost.

Description

The adjustment structure of CD player video disc degree of tilt

Technical field

The utility model relates to the CD player field, specifically is meant a kind of adjustment structure of CD player video disc degree of tilt.

Background technology

In the CD player field, all the time be placed on the dish platform in the video disc playing process, rely on dish platform high speed rotating under the drive of Spindle Motor to realize the tracking continuity of shaven head, and the relative distance variable quantity of video disc and shaven head directly has influence on the light beam focusing of shaven head, Gu guaranteeing to place video disc face (dish table top) is to ensure the key of reading the dish ability with being parallel to each other of bare headed face, all is at present by assembling the back dependent part product to be adjusted the depth of parallelism of proofreading and correct both.

At present, the adjustment mode of CD player Spindle Motor generally has two kinds on the market: a kind of for adjusting secondary guide rod inside and outside Tuesday of point and leading rod periphery a bit, by adjusting the master, the degree of tilt of secondary guide rod, guarantee the depth of parallelism of bare headed object lens and Spindle Motor dish platform, main, place below the secondary guide rod and adjust spring, by adjusting screw guide rod is adjusted, this kind adjustment mode is far away from Spindle Motor dish platform central shaft distance because of adjusting point, often producing dish table top and bare headed seat surface after the adjustment produces than mitre, influence video disc space up and down, especially read the dish ability and bring influence for the high ultrathin design movement of space requirement.Influence the machine-readable dish performance of dvd playback; Another kind of adjustment mode is directly to adjust Spindle Motor 3 points, this kind adjustment mode is adjusted a little near with Spindle Motor central shaft distance, even exist dimensional discrepancy also not have the error of amplification when adjusting, it generally is direct three locating shafts of riveting and overlap three springs thereon on shaven head seat, adjust by adjusting screw then, because of major and minor guide rod directly locked on the shaven head seat, this can require the dimensional accuracy of shaven head seat very high, improved the difficulty of bare headed seat mould and moulding, though this kind mode is adjusted comparatively accurate, cost of parts height, processing step are many.

The utility model content

At above-mentioned defective, the technical matters that the utility model solves is to provide a kind of adjustment structure of CD player video disc degree of tilt, and the degree of tilt that it can either adjust the CD player video disc more exactly can reduce parts again, reduces cost.

In order to solve above technical matters, the adjustment structure of the CD player video disc degree of tilt that the utility model provides, comprise shaven head seat, shaven head, secondary guide rod, leading rod and Spindle Motor, also comprise the motor bracket that is used for fixing Spindle Motor, described motor bracket is installed on the described shaven head seat, and the front of described motor bracket is provided with the axis of a cylinder that is used for fixing Spindle Motor, the keeper that is used to locate the hole of adjusting screw and is used to locate the placement elastomeric element; On one end of described leading rod and/or secondary guide rod/below be provided with elastomeric element and adjust screw.

Preferably, described motor bracket fixed leg is more than two.

Preferably, described screw pilot hole is more than two.

Preferably,, described elastomeric element is spring or shell fragment.

Preferably, described motor bracket, fixed leg, screw pilot hole and keeper are structure as a whole.

Preferably, the back side of described motor bracket is installed on the described shaven head seat by the circle fixed leg.

The adjustment structure of the CD player video disc degree of tilt that the utility model provides, also comprise the motor bracket that is used for fixing Spindle Motor, motor bracket is installed on the shaven head seat, and the front of motor bracket is provided with the axis of a cylinder that is used for fixing Spindle Motor, be used for placement positioning adjusts the hole of screw and be used to locate the keeper of placing elastomeric element; Be provided with below one end of described leading rod or secondary guide rod and adjust spring and adjust screw.Compared with prior art, this adjusts structural adjustment Spindle Motor 2 points, adjusts guide rod simultaneously a bit, the size of shaven head seat can suitably be relaxed, and mould and size are guaranteed easily, and it can either adjust the CD player Spindle Motor more exactly, can reduce parts again, reduce cost.
