Wherein the rotation shaft 321 rotates following the second gear 323 when the second gear 323 rotates in the second direction to rotate the catch tray mechanism 31, and is restricted from rotating when the second gear 323 rotates in the first direction. The double-sided optical disc changer further includes a second rack gear 7 located inside the housing 5, the second rack gear 7 being provided on the column 1 and extending in the vertical direction, being located on the second side of the disc housing 2 and being capable of meshing with the second gear 323. When the tray tilting assembly 3 moves to a second predetermined height in a direction away from the tray housing 2 on the second side, the second gear 323 engages with the second rack 7 to rotate in the second direction, so as to drive the rotating shaft 321 to rotate, and thus the tray-grabbing mechanism 31 to rotate.
The tilting tray mechanism 32 further comprises a limiting member 8, a first unlocking mechanism 9 and a second unlocking mechanism 10. The retaining member 8 has a hook 81, and the hook 81 is used for being caught in the aligned tooth grooves of the first gear 322 and the second gear 323 when the first gear 322 is not engaged with the first rack 6 to limit the rotation of the first gear 322, or is used for being caught in the aligned tooth grooves of the first gear 322 and the second gear 323 when the second gear 323 is not engaged with the second rack 7 to limit the rotation of the second gear 323. It can be understood that the tooth grooves of the first gear 322 and the second gear 323 are always aligned, so that the hook 81 can be simultaneously caught in the tooth grooves of the first gear 322 and the second gear 323.
The first unlocking mechanism 9 is disposed on the upright 1 and located on the first side of the disc cartridge 2, and is configured to move the hook 81 out of the tooth space where the first gear 322 and the second gear 323 are aligned when the flipping mechanism 32 drives the dual-sided optical disc 4 to return to the first side of the disc cartridge 2 and move by a first preset height. The second unlocking mechanism 10 is disposed on the upright 1 and located on the second side of the disk cartridge 2, and is configured to move the hook 81 out of the tooth slot where the first gear 322 and the second gear 323 are aligned when the disk-flipping mechanism 32 moves to the second side away from the disk cartridge 2 by a second preset height.
As long as the first gear 322 is disengaged from the first rack 6 or the second gear 323 is disengaged from the second rack 7, the hooks 81 on the limiting member 8 are all clamped in the aligned tooth grooves of the first gear 322 and the second gear 323, so as to prevent the tilting disk assembly 3 from tilting during the movement along the upright post 1.
As shown in fig. 8 and 9, the first unlocking mechanism 9 has a slope 91, and once the first gear 322 and the first rack 6 are engaged, the hook 81 of the stopper 8 contacts the slope 91, and when the tilting tray assembly 3 moves up along the upright 1, the hook 81 is pushed away by the slope 91, so that the hook 81 moves out of the aligned tooth slot of the first gear 322 and the second gear 323. In one embodiment, the second unlocking mechanism 10 is identical in structure to the first unlocking mechanism 9. The function of the hook 81 is to prevent the shaking of the tilting tray assembly 3 during the reciprocating motion on the upright 1 from causing the false rotation of the tray catching mechanism 31.
