Locative structure for grip slipper of optical disc carrying disc

Abstract

A clamping seat positioning structure of an optical disc carrying disc, which includes a carrying disc, a clamping seat and a positioning collar. A shaft tube protrudes from the bearing plate. The holding seat is provided with a middle hole, several holding pieces and several elastic elements, the inner wall of the middle hole forms a stepped part, and the holding pieces and elastic elements can elastically hold the optical disc. The positioning collar is provided with a radial flange. The inner wall of the positioning collar can be combined with the outer wall of the shaft tube of the carrier plate, and the outer wall of the positioning collar can be combined with the inner wall of the middle hole of the clamping seat, and the radial flange of the positioning collar can clamp the clamping seat The step part, thereby overcoming the defects of the prior art, effectively prevents the clamping seat from accidentally detaching from the carrier plate, and has the effect of increasing the assembly stability of the clamping seat.

Description

Technical field [0001] The invention relates to a positioning structure for a clamping seat of an optical disc carrier, in particular to an optical disc carrier that uses a positioning collar to firmly position and combine a clamping seat on a carrier to prevent the clamping seat from accidentally detaching Positioning structure of the clamping seat of the disc. Background technique [0002] For the positioning structure of the clamping base of the well-known optical disc carrier plate, please refer to figure 1 and 2 As shown, a general optical disc drive has a spindle motor, which usually includes a carrier plate 10, a clamping seat 20, a shaft 30, a fixed sub-assembly 40, a bearing seat 50 and a base plate 60. The carrier plate 10 is the rotor shell of the spindle motor, and a coupling portion 11 is embedded therein. The coupling portion 11 forms a shaft tube 111 and a shaft hole 112. The clamping base 20 is provided with a middle hole 21, a plurality of clamping members 22 an...

AI Technical Summary

Problems solved by technology

[0003] Although the tight-fit combination of the carrier plate 10 and the clamping base 20 can simplify and speed up the assembly process of the clamping base 20 of the spindle motor, the plastic material of the clamping base 20 has only a relatively low deformation margin compared with the metal material. Therefore, the inner wall (plastic) of the middle hole 21 of the clamping seat 20 cannot provide enough firm bonding force after the tight fit, so as to be permanently attached to the outer wall (metal) of the shaft tube 111 of the joint 11

Due to the lack of firm bonding force between the inner wall of the middle hole and the outer wall of the shaft tube 111 and poor assembly stability, when the user takes out the optical disc clamped on the clamping member 22 upwards, the clamping part 22 may be caused to be clamped together. The seat 20 is accidentally disengaged from the shaft tube 111 of the joint part 11 of the carrier plate 10
