Description

Improvement of Opening Structure of CD Box

technical field

The utility model relates to an improvement of an opening structure of a disc case, in particular to a pushing type positioning structure of the pivot joint of the disc case.

Background technique

Having entered the digital age, computers require a large amount of data input, and CD-ROM drives have become necessary equipment; CD-ROMs have also become essential components. Many software packages or audio-visual materials have been stored on CD-ROMs, making CD-ROMs an important data medium. There needs to be a storage space and a device to protect the CD, so it is the best choice to place the CD in a CD case.

As shown in Fig. 1 and Fig. 2, it is one of the most commonly used optical disc cases known, mainly suitable for the packaging of standard optical discs 10 with a diameter of twelve centimeters wide. The optical disc case is composed of a bottom cover 1 and a top cover 2 , the bottom cover 1 has a bottom plate 11, and the front and rear sides of the bottom plate 11 are respectively protruded with side strips 12 in a symmetrical manner near the periphery. Form a flange 13 so that the partition between the two side bars 12 becomes a pick-and-release opening 15 for the optical disc 10, and a left side plate 16 and a right side plate 17 are respectively connected to the left and right sides of the base plate 11, and a right side plate 17 is provided in the middle of the outer surface of the bottom plate 11. There is a groove 171 for opening; each side bar 12 extends outwards a protruding piece 19 toward the left side plate 16, and each protruding piece 19 has a rotating shaft 191 facing inwardly.

The top cover 2 has a top plate 21, the bottom surface of the top plate 21 protrudes from the left, the front and the rear and is respectively provided with side plates 24, 22, 23, and the right side of the top plate 21 is open, and the top plate 21 is located near the left side of the plate 24. At the corner, the top plate 21 has a gap 25 at the front and rear sides of the left side plate 24, and a pivot joint 26 is protruded from the left side plate 24 of the breach 25, and a pivot joint hole 261 is contained in the pivot joint plate 26 to pivot. The connecting hole 261 is connected with the rotating shaft 191, and the front side plate 22 and the rear side plate 23 of the top plate 21 are respectively provided with a fastening groove 221, 231. A protruding point 121 provided on the top is buckled and connected.

Since one end of the bottom cover 1 and the top cover 2 is connected to the rotating shaft 191 by a pair of pivot holes 261, and the other end is connected to the fastening grooves 221, 231 by two protruding points 121, since the two covers are getting thinner and thinner, the same The buckle is only pulled hard at the groove 171 and cannot be opened smoothly, which constitutes inconvenience in use and also affects the stability of the use process. Therefore, in order to provide items that are more in line with actual needs, the designer conducts research and development to solve the known problems. The problem of the positioning of the pivoting device.

Detailed ways

Referring to Fig. 3 to Fig. 6, it is an improvement of a disc case of the present invention, the case body 3 has a bottom cover 30 and a top cover 40, the bottom cover 30 and the top cover 40 are connected by a pivoting device, so that the bottom When the cover 30 and the top cover 40 are closed, the cover 30 and the top cover 40 are nested, abutted and socketed, and are unfolded in half by the pivot joint device.

Bottom cover 30 contains a bottom plate 31, bottom plate 31 near front side, near rear side are respectively provided with a front edge bar 32, a rear edge bar 33, the front edge bar 32, rear edge bar 33 are divided into symmetrical left and right halves section, and the middle of each side strip 32, 33 two halves is disconnected and unconnected, and becomes the pick-and-place opening of the optical disc, and a left side plate 36 and a right side plate 37 are respectively connected to the left and right sides of the base plate 31, And each side plate 36, 37 connects with each side bar 32, 33 to form a frame shape, and forms an accommodating space therein for positioning the optical disc.

The front side bar 32 and the rear side bar 33 each extend a protruding end 39 from the left side plate 36, and each protruding end 39 is provided with a slotted hole 38 opposite to each other, forming a part of the pivotal joint device, and the slotted hole 38 is not necessarily at the protruding end 39. , the pivot 48 described later can also be relocated at the protruding end 39.

The top cover 40 has a top plate 41, the left side, the front edge and the rear side of the bottom surface of the top plate 41 respectively have side plates 46, 42, 43 to form a U-shaped frame, wherein the top plate 41 is slightly larger than the bottom plate 31, and the top plate 41 is on the near left side. The front side plate 42 and the rear side plate 43 of the plate 46 respectively extend an extension end 47, and the extension end 47 has a pivot 48, and the oblong hole 38 in the shape of an oval is connected with the corresponding pivot 48 to form a pivot device. The shaft 48 does not have to be arranged at the extension end 47 , and the aforementioned elongated hole 38 can also be reconfigured at the extension end 47 .

When the front panel 42 and the rear panel 43 of the top cover 40 are covered respectively outside the front panel 32 and the rear panel 33 of the bottom cover 30, the lower ends of the front panel 42 and the rear panel 43 of the top cover 40 can be overlapped on the bottom cover 30 The bottom plate 31 of the bottom plate 31 is connected with the front edge bar 32 and the rear edge bar 33 on the outer side plate surface. And because the top cover 40 is larger than the bottom cover 30, the left side plate 46 of the top cover 40 is positioned at the outside of the bottom cover 30 left side plate 36, which forms a groove-like space. The plate 46 hooks out the box body 3 .

The front side plate 42 of top plate 41, rear side plate 43 interior surfaces are respectively provided with a protruding point 44,45, and the appearance of the front side bar 32 of base plate 31, the appearance of rear side bar 33 respectively establishes a guide groove 34,35, as shown in Figure 5, to protrude Points 44,45 are in contact with the openings of the arc-shaped or oblique guide grooves 34,35, so that the protruding points 44,45 move along the guide grooves 34,35 toward the pivot 48, that is, the top cover 40 is Push and move horizontally, the top cover 40 is just naturally fastened to the bottom cover 30, wherein the pivot 48 is moved from one end (inner end) of the elongated hole 38 to the other end (outer end), as shown in Figure 6, when untied , then reverse the action.

When the box body 3 is about to be opened, push the top cover 40 horizontally to drive the pivot 48 to move, follow the movement limit of the guide grooves 34 and 35 of the bottom cover 30, move to the other side away from the pivot 48, and move in the opening direction of the two covers , just make the top cover 40 and the bottom cover 30 close together and float up, and then it can be opened. At the openings of the guide grooves 34 and 35, press the top cover 40 downwards to naturally combine the two covers, and the top cover 40 will move obliquely downward along the guide grooves 34 and 35 to the end, naturally driving the movement of the top cover 40 , resulting in a close function.

To sum up the above-mentioned structure, the utility model uses a simplified structure, and only the top cover and the bottom cover are used to form the box body. The main difference from the known ones is that the pivotal positioning device is not a simple pivotal buckle, and the pivotal point is only The pivot is connected with the long hole, the inner end of the long hole is used as the positioning end, and the outer end of the long hole is used as the pivoting end, which is different from the known ones. In addition, the guiding and positioning function formed by the protruding point and the guide groove forms an oblique The function of pushing the opening and closing of the traversing type, so the utility model can provide good usability, and is a mechanism completely different from the known ones.

The above is a detailed description and drawings of the embodiments of the utility model, and is not intended to limit the utility model. All scopes of the utility model should be based on the following patent scope, and the spirit of the patent scope and the embodiments with similar changes Approximate structures should all be included in the utility model.
