The working principle of the utility model is:

One, when playing

Disc is inserted into the cabinet 1 from the opening 13, the disc of insertion is clamped in described by the clamping limb 4 On disc record 2.That is, the clamping piece 420 moves upwards and compresses the second spring 411, the lower part 415 of the clip It is resisted against on disc, disc is clamped on the disc record 2.

During disc is clamped in disc record 2, the edge of disc is resisted against on the push and block part 511 and drives The push and block part 511 is moved to the direction far from the disc record 2, and one end of first driving member 51 also rotates with it, i.e. institute The one end for stating the first driving member 51 is rotated to the direction far from the disc record 2.The torsional spring deformation, 611 He of the first elastic slice Second elastic slice 612 contacts, and the switch 61 is connected, and the control structure 6 works, and the motor 63 drives the disc record 2 Rotation.

At the same time, it described first is resisted against in the lateral projection 3222 against protrusion 512 originally, prevents the revolution Frame 322 rotates, that is, prevents the tone arm 3 from rotating to the direction close to the disc record 2, due to one end of first driving member 51 It is rotated to the direction far from the disc record 2, the other end of first driving member 51 is rotated to the direction close to the disc record 2. So that described first rotates against protrusion 512 to the direction close to the disc record 2, described first is no longer abut against against protrusion 512 In the lateral projection 3222, the lateral projection 3222 is lost against power, and the reversing frame 322 rotates.The tone arm 3 It is rotated to the direction close to the disc record 2, the revolving bed 32 drives the tone arm 3 to be moved to the upper of disc from stand Side, the record contacts of the pickup 31 and rotation, the lateral projection 3222 are resisted against on the lateral supporter 522.At this point, The phonograph work, the loudspeaker 64 send sound.

During broadcasting, the pickup 31 is first located on the outer ring of disc, described to sing with the growth of play time First 31 is mobile to the inner ring of disc, and the reversing frame 322 is resisted against the transverse direction and supports also with rotation, the lateral projection 3222 On lever 522, so that second driving member 52 is also with rotation.When the pickup 31 is moved to the innermost circle of disc, i.e., Disc has finished, and at this moment, the other end of second driving member 52 is resisted against in the rotary spacing protrusion 151, institute Third camber of spring is stated, second driving member 52 no longer rotates, and the reversing frame 322 also no longer rotates, and the tone arm 3 is not yet It is rotated further by, disc continues to rotate, and the pickup 31 is always positioned in the innermost circle of disc.

Two, disc is taken out

The impeller 53 is pushed, the other end of second driving member 52 is rotated to the direction far from the disc record 2, institute It states first to be resisted against in the lateral projection 3222 against protrusion 512, and rotates the reversing frame 322, the reversing frame 322 The tone arm 3 is driven to rotate to the direction far from the disc record 2, i.e., the described revolving bed 32 drives the tone arm 3 to return to and parks position It sets.One end of second driving member 52 is rotated to the direction close to the disc record 2, the torsional spring recovery deformation, and described first One end of driving member 51 is resisted against on first elastic slice 611, so that first elastic slice 611 and second elastic slice 612 divide It opens, the switch 61 disconnects.The control structure 6 stops working, and the motor 63 stops that the disc record 2 is driven to rotate.

In the rotation of one end of second driving member 52, the push and block part 511 is resisted against the edge of disc, described to push away Block piece 511 drives disc mobile to the direction far from the transmission mechanism 5 on the disc record 2 so that a part of disc from The opening 13 reaches the outside of the cabinet 1, takes disc away.

The utility model is sung due to using the clamping limb, the revolving bed and the transmission mechanism when needing to play When piece, it is only necessary to which disc, which is inserted into phonograph, to be played, and when needing to take out disc, the transmission mechanism is driven to transport It is dynamic, a part of disc will be shifted out to take disc away from phonograph, facilitate pick-and-place disc；Regardless of the phonograph is put Can where be set, the phonograph play a record, even if mentioning the phonograph on hand, the phonograph still be broadcast It plays a disc, has many advantages, such as that easy to carry, broadcasting is convenient and it is convenient to pick and place disc.

It should be noted that being explained in detail for the respective embodiments described above, purpose be only that the utility model into Row explain, in order to be able to preferably explanation the utility model, still, these description cannot with any explanation at be to this The limitation of utility model, in particular, each feature described in various embodiments can also mutual any combination, thus Other embodiments are formed, in addition to there is clearly opposite description, these features should be understood to can be applied to any one reality It applies in mode, and is not limited merely to described embodiment.
