Abstract

The utility model discloses a main shaft motor bearing disk and the utility model is for bearing the CD or DVD disk and is a component of a CD or DVD player. The character of the utility model is that the utility model comprises a constitution strengthening structure, a stop slide cloth formation and combination structure and a resisting close bearing plate device. The constitution strengthening structure is that a disk body stent 2 is injection molding in a die and is connected with a disk seat 3 and thus is processed a second injection molding in a bearing plate die. The disk body stent 2 is covered by the bearing plate to integrate as a whole and the constitution is strengthened and the rotating stability is improved. The stop slide cloth is a concentric round concave groove12 which is arranged on the plate surface and the concave groove is injected with aqueous resin or composition. The aqueous resin or the composition freezes and forms the stop slide cloth 4 and the stop slide effect and the level effect is realized at one time. The resisting close bearing plate device is that the center convex circumference of the disk body stent 2 is provided with three steel ball ports 23 and an assembling room 24 which is on the inner surface and is corresponding to the steel ball port. The assembling room 24 is provided with a steel ball 5, a U type shrapnel 6 or a rubber block 7, a compelling close stent 8. The U type shrapnel 6 or the rubber block 7 flexibly presses the steel ball 5 to make the spherical part of the steel ball 5 enters the steel ball port23 to closely resis the bearing slice to prevent slide in the rotating process.

Description

The Spindle Motor carrier

The utility model relates to the Spindle Motor carrier that carries CD or DVD sheet in a kind of CD or the DVD player.

At present, in relevant CD or the DVD player, the Spindle Motor loading plate that is used for carrying CD or DVD sheet all is processed into copper coin, and coil on the seat in conjunction with being fixed in central shaft, because its material and processing cost are all high, so the design people's test is made of injection mo(u)lding, but, directly one piece injection mo(u)lding, the tiltedly poor and card degree of rocking of its washing shrinkage, degree of deformation, card be all up to 0.1mm, poor practicability.

In addition, be to paste the on-slip member of one deck slide-resistant fabric on the existing carrier card as CD or DVD, time-consuming when pasting slide-resistant fabric, the processing cost height, furthermore make on-slip effect forfeiture along with the inefficacy of viscose glue.Other utilizes attraction to fix or other fixed form fixes, and still, its function that prevents the carrying tablet slip is all not satisfactory.

The purpose of this utility model provides the Spindle Motor carrier that a kind of cost is low, anti-slip effect good, quality is high.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

The utility model includes Spindle Motor carrier physique and adds competent structure, slide-resistant fabric formation and combined structure and hold out against the carrying tablet device, it is that bag is provided with disc body support in carrier that its Spindle Motor carrier physique adds competent structure, this disc body support is that injection mo(u)lding combines with the dish seat in mould, place quadric injection mould moulding in the carrier mould again, disc body support is coated by carrier to be combined into one, in order to strengthen the physique of carrier, to promote the carrier stability of rotation; Slide-resistant fabric forms and combined structure is, the carrier card is established a concentric round recessed, is provided with injection water-base resin or complex in this groove and solidifies the slide-resistant fabric of formation, skids in order to prevent carrying tablet; Holding out against the carrying tablet device is to be provided with three steel ball holes that are equally spaced at disc body support center protuberance periphery, its inner face is provided with the assembly room that matches and answer, in order to the installing stainless shot, assemblies such as the block rubber of U-shaped shell fragment or high-low temperature resistant and clamping base, it is to oppress steel ball protrusion steel ball hole with the elasticity of U-shaped shell fragment or block rubber to hold out against carrying tablet, skids during in order to the rotation of prevention carrying tablet.

The utility model will be further described below in conjunction with drawings and Examples:
