Abstract

The invention discloses a disc-pressing device of a CD player, which comprises a disc-pressing cover, a disc-pressing seat and a disk cover spring plate respectively matched with the disc-pressing cover and the disc-pressing seat. The disc-pressing seat is provided with an upper fixed part and a lower fixed part; the disk cover spring plate is provided with a limit platform, a downward bend matched with the upper fixed part and a limit bend, the disc-pressing cover is provided with a limit groove matched with the limit bend, a lug boss matched with the lower fixed part and a protrusion matched with the limit platform, and the disc-pressing cover is arranged between the disk cover spring plate and the lower fixed part. In the disc-pressing device of the CD player, the disc-pressing cover is simultaneously positioned by the coaction of the disk cover spring plate and the disc-pressing seat so that the disk cover spring plate can have a smaller size, be made of thinner plates and have easily controlled size precision, low plate cost and relatively simple and convenient assembly.

Description

technical field [0001] The invention relates to an optical disc player, in particular to a disc pressing device of the optical disc player. Background technique [0002] The disc pressing device is an important component of the optical disc player mechanism. It is responsible for pressing the disc on the designated surface after the disc is in place and assisting the high-speed rotation of the disc. The key to the device is to reliably connect the gland seat, the elastic disc cover spring plate and the pressure disc cover. The current connection method is mainly to lock the disc cover spring plate on the gland seat by screws, and then pass the spring plate to support the platen cover. This structure has two disadvantages: one is that the disc cover is completely positioned by the disc cover spring plate, the design area of ​​the disc cover spring plate is large, and the cost of the parts is high; the other is that because the disc cover spring plate is an elastic body, it i...
