Clampingpiece structure for inhalation type CD machine

Abstract

The invention discloses a suction-type CD player clamping piece structure. An upper chassis and a lower chassis are nested to form a chassis, the front end of the chassis is connected with a panel, the upper chassis is provided with a central hole, a pressure ring is arranged at the periphery of the central hole and is concaved-down to form a stage shape, a guide channel is concaved-down to be arranged at the periphery of the pressure ring facing the front end of the chassis, one end of the guide channel obliquely extends from the pressure ring to the surface of the upper chassis, a convex rib part is convexly arranged in the guide channel through punching, a plurality of strengthening ribs are concavely arranged at the periphery of the pressure ring in a dispersed and radial manner, and a side wall bends upwards at the inner periphery of the pressure ring so as to enhance the strength of the clamping piece.

Description

technical field [0001] The invention relates to a slot-in type optical disc drive, in particular to a clip structure for clamping optical discs in the slot-in type optical disc drive. Background technique [0002] The slot-in optical disc drive uses the guide rod to automatically suck in the disc, guide it to the playback position, or automatically guide the disc out of the disc drive, and can directly insert or take out the disc, without the need for a telescopic tray to carry the disc. It is more convenient to use and widely used. Favored by consumers. [0003] see figure 1 , is the existing slot-in optical disk drive 1, its casing is made of upper casing 2 and lower casing 3, a panel 4 is established at the front end of the casing, and an inlet and outlet 5 is provided on the panel 4 for optical disc D (referring to the figure 2) Inserting or withdrawing the optical disc drive, the center of the upper case 2 is provided with a central hole 6, and the periphery of the ce...

Problems solved by technology

[0005] However, in order to avoid obstructing the optical disc D and to guide the insertion of the optical disc D smoothly, a part of the step-shaped pressure ring 7 is formed into a flat and inclined guide groove 8, so that the pressing force is stronger than that of the pressure ring 7. The strength is weak, and the guide groove 8 is easily deformed when pressing the fixing hole 12 (as shown by the dotted line), and cannot evenly press the surroundings of the fixing hole 12, causing the optical disc D to be skewed, and the fixing hole 12 of the optical disc D cannot be inserted normally. into the turntable 9, resulting in the clip failure, or even damage to the disc

In addition, in order to reduce weight, the metal casing of the slot-in optical disk drive is getting thinner and thinner. Under the turntable 9 with a limited rising height, the casing cannot provide sufficient support structure strength for the pressure ring 7, which is more likely to cause the clip to fail.
