Description

A disc lock mechanism, a disc cartridge, a disc cartridge and a disc cartridge

Technical field

The present invention relates to an optical disc magazine assembly for an optical disc library, and more particularly to an optical disc cartridge locking mechanism, a disc cartridge housing, an optical disc cartridge, and a disc magazine.

Background technique

Optical disc library is a kind of opto-mechanical mass data storage device with standardized optical disc as data storage medium, which is widely used for long-term archival preservation of data. In the prior art, the most occupied space in the optical disc library is the storage portion of the optical disc, which is usually composed of a plurality of modular side-opening disc magazines, and each disc magazine is provided with a plurality of disc holders arranged side by side. A disc holder is stacked to set a disc cartridge containing the disc cartridge, and the disc is stored in the disc cartridge. When it is necessary to move the disc cartridge from one disc library to another disc library, or when the disc needs to be removed from the disc library after the disc is damaged, it is necessary to manually access the disc cartridge operation; when the disc library information is cleared A large number of discs that need to be cleaned are removed from the disc library, and the manual operation of the disc cartridge is required. When the robot fails to work when the power is off, the manual operation of the disc cartridge is also required. Since the disc magazine needs to be pulled from the front side, the disc cartridge can only be accessed from the side opening of the disc magazine. However, the overall size of the disc magazine is limited. In order to improve space utilization, the disc cartridge is adjacent to the upper, lower, left and right sides. The space between the jewel cases is small, and it is difficult to take the jewel case by hand.

At the same time, when the disc magazine is taken out from the disc library, if the disc library is not placed in a horizontal position, the disc cartridge may slip off the side opening of the disc magazine, causing personal danger and economic loss, so it is necessary to set the disc cartridge. The locking mechanism allows the disc cartridge to be smoothly fixed in the disc magazine.

Summary of the invention

In order to overcome the deficiencies of the prior art, the present invention aims to provide a disc cartridge locking mechanism, a disc cartridge accommodating compartment, a disc cartridge and an optical disc magazine, and the device of the present invention can conveniently take the disc cartridge without the aid of a robot. , improve the efficiency of loading the disc, the space utilization of the disc magazine and the physical stability of the disc storage.

In order to solve the above technical problem, the present invention provides a disc cartridge locking mechanism including a tailgate, a spring, a pusher, a lock body and a lock tongue, wherein one end of the spring is fixed on the tailgate. The push piece is connected to the other end of the spring, and the lock body has an elongated shape, and an inner portion of the lock body is formed with an elongated lock body cavity, and an end of the lock body is fixed on the tailgate. The front end of the lock body is provided with a locking notch near the side of the optical disc case, and the locking tongue has an elongated shape, and the end of the locking tongue passes through the cavity of the lock body and is connected with the push piece. The front end of the bolt is provided with a protruding latch. When the disc cartridge pushes the pusher piece inwardly to the locking position, the latch protrudes from the corresponding locking notch and is inserted into the corresponding recessed hole on the side of the disc cartridge.

Specifically, the CD case locking mechanism further includes an unlocking pad, and when the unlocking paddle is moved away from the disk cartridge, the unlocking pad drives the locking tongue to be offset, thereby enabling the The latch is disengaged from the locking notch and the disc cartridge is unlocked.

Preferably, the front end of the unlocking paddle is flush with the front end of the lock body.

The invention has the following two technical solutions: the unlocking paddle is a portion of the locking tongue extending toward the front end, or the unlocking paddle is an elastic strip whose end is fixed on the locking body.

It should be noted that the front end portion of the locking tongue is an elastic section, and when in the unlocked state, the elastic section is deformed so that the locking buckle is in close contact with the side wall of the locking body cavity.

Preferably, a limiting strip for limiting the deviation of the spring is provided on the tailgate near the fixing spring.

Accordingly, the present invention also provides a disc cartridge housing, comprising a disc cartridge locking mechanism as described above and a side panel, the disc cartridge locking mechanism and the side panel forming a storage disc cartridge The space of the disc cartridge locking mechanism and the side panel are correspondingly provided with a supporting guiding structure that cooperates with the disc cartridge.

Specifically, a support plate is disposed at a corner connecting the lock body and the tailgate, and the support plate is in contact with a concave surface at a corner of the optical disc case.

Accordingly, the present invention also provides an optical disc case having a side wall having a recessed hole that cooperates with a latch of the disc cartridge locking mechanism as described above.

In particular, a corner of the bottom surface of the disc cartridge has a concave surface that cooperates with a support plate of the disc cartridge housing as described above.

Accordingly, the present invention also provides an optical disc magazine comprising a side opening magazine body and a plurality of disc holders, the disc holder comprising a plurality of stacked disc housings as described above, the disc holder The cartridges are sequentially arranged and fixed.

The principle of the invention is that when the optical disc case is stored in the optical disc magazine, the optical disc box is pushed to push the light The pusher on the rear of the disc cartridge, while the pusher strap is moved inwardly until the disc cartridge completely enters the disc holder to reach the locked position, at which time the latch on the latch protrudes from the corresponding locking notch and is inserted into the disc. In the corresponding concave hole on the side of the box, the optical disc case is locked, so that the spring is kept in a compressed state; when it is required to take the optical disc case, the human hand toggles the unlocking paddle, and the unlocking paddle drives the locking tongue away from the CD case to disengage the locking buckle from the lock. When the notch is not in use, the spring is not subjected to the restraining force and rebounds to the pusher until the spring is reset, and at the same time, the pusher pushes the stored disc cartridge toward the exit direction until the spring reaches the uncompressed state, and the disc cartridge is pushed out. A distance can be easily removed by hand.

According to the above technical solution, the invention has the following beneficial effects: 1 the unlocking paddle is a thin strip, and the position of the unlocking paddle is not intentionally left between adjacent disc cartridges, which saves space and improves the space utilization of the disc magazine. Rate; 2The unlocking paddle is an elastic strip. The smaller the force, the latch can be disengaged from the locking notch, and the corresponding disc box is automatically ejected under the action of the spring, which is convenient for manual removal; 3 whether it is locked or unlocked In the state, the front end of the pick-up piece does not exceed the front end surface of the lock body, so the space in the optical disc library is not occupied, and the unlocking pick-up ejecting disc box can be used to facilitate manual removal without affecting the robot to store the disc case. Operation; 4 The disc cartridge is locked by the lock when the disc is stored, that is, when the disc cartridge is taken out from the disc library, the disc cartridge does not fall off the disc library due to factors such as whether the placement position is horizontal or the like. In summary, the present invention can easily and easily access the optical disc case without expanding the overall space of the optical disc magazine and without affecting the operation of the robot, thereby improving the space utilization of the optical disc magazine and the physical stability of the optical disc storage.
