Description

A disc case with a locking device

technical field

The utility model provides an optical disc case, in particular to an optical disc case with a locking device.

Background technique

Usually provide storage media for computers, information and entertainment appliances, including audio tapes, video tapes, floppy disks, hard disks, CDs, VCDs, DVDs and other items; with the advancement of technology, various machines for reading storage media have gradually become popular. Especially VCD or DVD disc players are widely used by the public, and various optical discs are circulated in the market in large quantities, so disc rental shops are followed; The discs are kept together in the case and placed on the shelf for customers to choose. The disc case is usually two-piece and simply closed. Therefore, the industry provides a lockable and fixed optical disc box structure, the main structure of which is shown in Figure 1, which includes:

A disc case 10 is made up of upper and lower casings 101, 102. The opening sides of the casing are respectively provided with a front embankment 1011, 1021, and two convex ribs 1041, 1051 are respectively arranged in the ラ-shaped grooves on both sides. , and a hole 106, 107 is provided in the center;

A locking member 20 is provided with a group of opposite through holes 201 on both sides, and a hook body 202, 203 is provided on the edge; in addition, a protrusion 204 is provided in the center of the locking member 20, please refer to FIG. 2 As shown, the cards can be inserted into the holes 106, 107 of the disc case 10, and the hooks 202, 203 on both sides are inserted into the ribs 1041, 1051 to fasten, so as to fix the upper and lower shells 101, 102 cannot be opened;

An opening member 30 has a convex portion 3011, 3021 protruding upwards on both sides of its end surface, which can be inserted into the through hole 201 of the locking member 20, and squeeze the hook body 202, 203 to separate from the convex rib 1041, 1051 , and then the locking member 20 and the disc case 10 are disengaged, whereby the store can use the opening member 30 to unlock the disc case when the consumer selects the film, so as to prevent thieves from opening the disc case by themselves to take away the optical disc in it .

However, there are still many missing problems in the above-mentioned locking and fixing structure to be solved: the upper and lower casings 101, 102 of the optical disc casing 10 themselves are flexible, and there are no fixing members on both sides, and the hooks 202, 102 are flexible. 203 is only fastened against the convex ribs 1041, 1051, and only the central projection 204 of the locking member 20 is inserted into the holes 106, 107 of the optical disc case 10. Please refer to Fig. 2 for cooperation, so the upper and lower Both sides of casing 101, 102 are easy to be pried open, and the optical disc shell 10 forms a state of being pulled apart, and the optical discs placed in it are easy to be stolen; troubled.

Moreover, the hook bodies 202, 203 are only fastened against the convex ribs 1041, 1051, and there are no blocking members on the upper and lower sides of the hook bodies 202, 203. Please refer to Figs. The tool stretches into the pushing hook body inwardly to unlock from the gap between the side of the lock piece and the optical disc shell; therefore, the anti-theft effect is still not ideal.

Contents of the invention

The purpose of this utility model is to improve the deficiencies in the prior art, and provide a kind of optical disc box after the upper and lower boards are covered correspondingly, and the locking piece covers the box, and the upper and lower boards are covered, which can be firmly locked. , A disc case with a locking device that prevents it from being pried open.

A further object of the present invention is to provide a disc case with a locking structure that can only be unlocked by using a specific unlocking element to prevent people from using tools to unlock at will, thereby increasing the anti-theft effect of the disc case.

The purpose of this utility model is achieved in that:

The utility model provides an optical disc case with a locking device, which has an upper and a lower case body which can be closed correspondingly to accommodate discs, a locking piece is sleeved on the open side of the upper and lower case body and Locking, once the locking piece is unlocked, the locking piece can be opened and separated from the upper and lower boxes, and the upper and lower boxes can be unfolded for use; it is characterized in that:

The upper and lower boxes are respectively provided with a predetermined number of fastening posts on the opening sides of the upper and lower boxes, and the fastening posts are independent of each other;

The locking piece, in order to reliably connect the upper and lower boxes, and is provided with an equal number of locking members corresponding to the locking column, and the locking members are arranged in a circle with a plurality of locking pieces that can be expanded and shrunk. There is a perforated groove at the center of the catch member, which communicates with the inner surface of the catch piece; It is fixedly connected to the locking piece to form a multi-point locking structure, which can be folded and used;

The unlocking element is provided with an equal number of jacking posts corresponding to the latching member corresponding to the locking piece, and the structure of the jacking post is matched with the perforated groove and the latching piece of the latching member, such as the length and cross-sectional size, Make it extend into the perforated groove of the locking member at the top column, and push the locking piece to make it open, and at the same time break away from the locking column of the upper and lower box bodies, the unlocking element, the locking The upper and lower box bodies can be taken out to release the sheet.

The inside of the opening side of the upper and lower plates is provided with the fastening column, and the upper plate of the optical disc case is provided with an equal number of hollow grooves corresponding to the fastening column of the lower plate, such as U-shaped grooves, Or an equal number of hollow grooves are provided on the plate body of the lower plate body corresponding to the clamping column of the upper plate body, so that when the upper and lower plate bodies are covered, the clamping column fits the hollow groove, The fastening posts on the upper and lower boards are arranged at equal heights.

The fastening column of the upper and lower boards has a large-diameter fastening end formed at its front end; a hook edge is formed on the inner top end of the catch piece of the locking piece, and the hook edge of the catch piece hooks the card. The joint end forms a clamping joint structure.
