Description

Disc player with disc clamping device {DISC PLAYER HAVING APPARATUS FOR CLAMPING DISC}

The present invention relates to a disc clamping apparatus of a disc player, and more particularly, to a coupling structure that allows a clamp and a clamp fixing holder to be coupled more stably.

A disc player for reproducing information recorded on a disc is provided with a disc clamping device for clamping the disc to rotate the disc inserted into the disc player.

1 to 3 show the structure of a disc player having a conventional disc clamping device, FIG. 1 is an assembly view of a disc player, FIG. 2 is an assembly view of a clamp and a clamp fixing holder, and FIG. 3 is an enlarged view of a main part. It is a cross section.

As shown in FIG. 1, a conventional disc player is provided with a disc clamping device for firmly clamping a disc (not shown) to the turntable 20. As shown in FIG.

The disk clamping device includes a clamp fixing holder 40 fixed to the deck 10 and a clamp 50 coupled to the fixing holder 40, and the disk clamp 30 of the deck 10 through the disk tray 30. When a disk (not shown) inserted into the turntable 20 is seated, the clamp 50 comes into close contact with the disk and clamps it.

As shown in FIG. 2, the clamp fixing holder 40 has a coupling hole 43 formed at the center thereof, and the clamp 50 is detachably mounted to the coupling hole 43.

In more detail, the clamp 50 has a fixing groove 51 is formed in the edge portion 52 of the wing, the clamp fixing holder 40 is a locking jaw 41 protruding inward to the coupling hole 43 and; A support jaw 42 formed below the locking jaw 41; It comprises a supporting means configured to include.

Therefore, when the clamp 50 is inserted into the coupling hole 43, the locking jaw 41 of the clamp fixing holder 40 passes through the fixing groove 51 of the clamp 50, all the locking jaw formed radially After the 41 passes through the fixing groove 51, the clamp 50 is rotated a predetermined angle in an arbitrary direction, so that the edge of the blade of the clamp by the groove 44 between the locking jaw 41 and the supporting jaw 42. Since the portion 52 is positioned and supported by the locking jaw 41 and the supporting portion 42, the clamp 50 is coupled to the clamp fixing holder 40.

By the way, since such a clamp device supports the upper side of the turntable on which the disk is mounted, it is inevitably directly exposed to vibration, and the fixing groove (b) in the edge portion 52 of the blade of the clamp 50 as described above. 51 is formed so that the fixing groove 51 is inserted into the support means formed in the coupling groove 43 of the clamp fixing holder 40 and the clamp 50 is engaged by rotating by a predetermined angle, by vibrating As the clamp 50 performs an unexpected rotational movement, the position of the fixing groove 51 is fixed to the locking jaw 41 while the edge portion 52 of the clamp 50 is pushed in one direction of the coupling hole 43. ), The fixing groove 51 passes through the locking jaw 41 and the clamp 50 can be separated from the clamp fixing holder 40.

In order to solve this problem, a method of coupling the clamp 50 to the lateral direction by forming a coupling guide hole in the lateral direction of the clamp fixing holder 40 has been proposed, but such a method has a high strength of the clamp fixing holder 40. There is a problem that the structure is vulnerable to degradation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a disc player having a disc clamp device that has a structure that allows the clamp to be coupled more stably without detaching from the clamp fixing holder.

In order to achieve the object as described above, the present invention, a disk having a disk clamping device comprising a clamp for pressing and fixing the disk seated on the turntable, and a clamp fixing holder having a coupling hole of the clamp and fixed to the deck A player, wherein the clamp comprises: an elastically deformed evacuation portion that is a through hole formed at an edge portion of the wing thereof; An elastic deformation portion capable of elastic contraction as an outer portion of the through hole; It includes a fixing means configured to include, wherein the clamp fixing holder and the locking projection protruding inwardly in the coupling hole to be coupled to the clamp by elastic contraction of the elastic deformation portion; A support jaw formed at a lower side of the locking jaw to support an edge portion of the wing of the clamp; A disc player having a disc clamping device, comprising a support means configured to include.

In addition, it is preferable that the clamping means of the clamp and the supporting means of the clamping holder are formed as a radial structure at a position corresponding to each other.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

4 and 5 show the structure of a disc player having a disc clamping device according to the present invention. FIG. 4 is an assembly view of a clamp and a clamp fixing holder, and FIG. 5 is a plan view of the clamp.

Basically, a disc player according to the present invention is provided with a disc clamping device for firmly clamping a disc (not shown) to the turntable 20, which disc clamping device is clamped holder fixed to the deck 10. And a clamp 100 coupled to the fixed holder 200, and a disc (not shown) drawn into the deck 10 through the disc tray 30 is attached to the turntable 20. When seated, the clamp 50 has the same structure as the conventional case in that the clamp 50 is in close contact with the disk to perform clamping.

4 and 5, however, the clamp 100 includes an elastically deformed evacuation portion 101 which is a through hole formed in the edge portion 103 of the wing thereof; An elastic deformation portion 102 capable of elastic contraction as an outer portion of the through hole; It includes a fixing means configured to include, the clamp fixing holder 200 is a plurality of engaging protruding inwardly in the coupling hole 210 to be coupled to the clamp 100 by the elastic shrinkage of the elastic deformation portion 102 Jaw 211; A support jaw 212 formed under the locking jaw 211 to support the edge 103 of the wing of the clamp 100 coupled thereto; It is characterized in that it comprises a supporting means configured to include.

That is, by forming the through hole at the edge of the blade of the clamp 100, the through hole constitutes the elastic deformation evacuation portion 101, the outer portion of the through hole constitutes the elastic deformation portion 102, The outer diameter of the elastic deformation portion 102 is formed to be substantially the same as the outer diameter of the edge portion 103.

When the clamp 100 having such a structure is coupled to the coupling hole 210 of the clamp fixing holder 200, the process is as follows.

The outer diameter of the edge portion 103 and the elastic deformation portion 102 of the clamp 100 is formed by the projection of the engaging jaw 211 and the supporting jaw 212 formed in the coupling hole 210 of the clamp fixing holder 200 Since it is larger than the inner diameter, when the clamp 100 is inserted into the coupling hole 210, the elastic deformation portion 102 of the clamp 100 is caught in the locking jaw 211 of the clamp fixing holder 200.

At this time, when a predetermined pressure is applied in the direction of the coupling hole 210 in the clamp 100, the elastic deformation portion 102 of the clamp 100 causes elastic contraction to the elastic deformation evacuation portion 101 side, that is, the inner direction is locked. Since the jaw 211 can be passed through, the clamp 100 main body eventually passes through the engaging jaw 211 of the coupling hole 210 of the clamp fixing holder 200.

Since, the upper side of the edge of the wing of the clamp 100 is supported by the locking jaw 211, the lower side is supported by the supporting jaw 212, thereby taking a stable coupling structure as a whole.

Comparing the coupling structure of the present invention with the conventional one, in the conventional case, the vibration direction due to the rotation of the disk mounted on the turntable and the mounting direction of the clamp are the same. Since the vibration direction and the mounting direction of the clamp are different from each other, there is a remarkable difference in that there is little fear that the clamp will be separated from the clamp fixing holder even if the clamp device is vibrated.

In addition, in order to achieve a more stable coupling structure, it is preferable that the fixing means 101 and 102 of the clamp 100 and the supporting means 211 and 212 of the clamp fixing holder 200 are formed as a radial structure at a position corresponding to each other. .

The present invention provides a disc player having a disc clamp device that has a structure that allows the clamp to be coupled more stably without detaching from the clamp fixing holder.
