Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical disc case technology, specifically a BD optical disc case with a protective structure. Background Technology
[0002] Blu-ray discs, also known as BD discs, are high-definition audio-visual storage optical disc media that followed DVDs. They utilize a shorter wavelength blue laser to read and write data, hence the name. Blu-ray significantly increased the storage capacity of optical discs, providing a leapfrog development opportunity for optical storage products.
[0003] A BD disc case is a box used to store BD discs. During use, there is a risk of it being dropped. When a BD disc case is dropped, it lands on its sharp corner, which can easily cause damage. Furthermore, the BD disc case only relies on its own elastic snap-fit structure to close, which makes it easy for the BD disc case to open upon impact when dropped. Therefore, a BD disc case with a protective structure is proposed to optimize the existing BD disc case. Utility Model Content
[0004] The purpose of this invention is to provide a BD disc case with a protective structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A BD disc case with a protective structure includes an upper case, a lower case, and a BD disc. Guide sleeves are fixedly embedded at each of the four corners of the lower case. A matching guide rod is slidably connected within each guide sleeve. An arc-shaped guard is fixedly connected to the end of each guide rod. The thickness of the arc-shaped guard is greater than the thickness of the BD disc case. Support rods are symmetrically hinged to both sides of the arc-shaped guard. A slider is hinged to the end of each support rod. The slider is slidably connected within a groove. The groove is fixedly connected to the corresponding outer wall of the lower case. A crossbar is fixedly connected within each groove. The crossbar slidably passes through the slider, allowing the slider to slide against the groove and be confined within the groove by the crossbar. A first spring is provided between each side of the slider and the inner wall of the groove end. The first spring is sleeved on the outside of the crossbar. The two first springs elastically limit the slider to the middle position of the groove.
[0007] As a further embodiment of this utility model: the upper box body is placed on top of the lower box body, and the rear surfaces of the upper box body and the lower box body are hinged together. The upper box body and the lower box body are both provided with a placement cavity, in which the BD disc is placed. The placement cavity on the lower box body is provided with a claw, in which the BD disc is secured. The claw can be elastically deformed to facilitate the placement, fixing and removal of the BD disc.
[0008] As a further improvement of this utility model: the front side of the upper box is symmetrically provided with through notches, and the middle part of the upper box corresponding to the through notches is provided with a horizontal slot, and a matching block is provided in the horizontal slot.
[0009] As a further improvement of this utility model: a pull block is fixedly connected to the card block, and the pull block is a pyramidal design.
[0010] As a further improvement of this utility model: an elastic mechanism is provided between the card block and the lower box body, the elastic mechanism including a step connecting rod and a second spring.
[0011] As a further embodiment of this utility model: the step connecting rod movably passes through the lower box and is fixedly connected to the locking block. The bottom surface of the lower box has a step groove adapted to the step connecting rod, and the second spring is located in the step groove and sleeved on the outside of the step connecting rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model has arc-shaped protection at all four corners of the lower box. The guide rod and guide sleeve work together to guide the movement, and the support rod provides auxiliary support. When the support rod is supporting, the slider can be limited to the middle position of the slide groove by the first spring and the crossbar. Thus, when it falls, the arc-shaped protection can buffer the impact and prevent the sharp corner of the BD disc box from falling directly and causing damage, reducing the possibility of damage from falling.
[0014] 2. This utility model uses a stepped connecting rod and a second spring in conjunction with a stepped groove to form an elastic mechanism, which can tighten the locking block and keep the locking block rotatable. The locking block can penetrate the upper box body through the cooperation of the locking block and the through notch. At the same time, the upper box body can be limited by the cooperation of the locking block and the transverse locking groove, so that the upper box body is closed, effectively preventing the elastic buckle from deforming and loosening after a collision.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 In this embodiment of the present invention, a BD disc case with a protective structure includes an upper case 1, a lower case 2, and a BD disc 3. Guide sleeves 4 are fixedly embedded at the four corners of the lower case 2. Guide rods 5 adapted to the guide sleeves 4 are slidably connected inside the guide sleeves 4. Arc-shaped guards 6 are fixedly connected to the ends of the guide rods 5. The thickness of the arc-shaped guards 6 is greater than the thickness of the BD disc case. Support rods 7 are symmetrically hinged to both sides of the arc-shaped guards 6. Slider 8 is hinged to the ends of the support rods 7. Slider 8 is slidably connected in a slide groove 9. The slide groove 9 is fixedly connected to the corresponding outer wall of the lower case 2. Horizontal bars 10 are fixedly connected in the slide groove 9. The horizontal bars 10 slide through the slider 8. The slider 8 slides in contact with the slide groove 9 and is limited in the slide groove 9 by the horizontal bars 10. First springs 11 are provided between the two sides of the slider 8 and the inner wall of the end of the slide groove 9. The first springs 11 are sleeved on the outside of the horizontal bars 10. The two first springs 11 elastically limit the slider 8 to the middle position of the slide groove 9.
[0022] Arc-shaped guards 6 are provided at all four corners of the lower housing 2. The guards move and guide the lower housing through the cooperation of the guide rod 5 and the guide sleeve 4. At the same time, the guards 7 provide auxiliary support. When the guards 7 are supporting the lower housing, the slider 8 can be limited to the middle position of the slide groove 9 by the first spring 11 and the crossbar 10. Thus, when the lower housing is dropped, the arc-shaped guards 6 can provide cushioning, preventing the sharp corners of the BD disc case from hitting the ground directly and causing damage, thus reducing the possibility of damage from falling.
[0023] The upper box 1 covers the lower box 2. The rear surfaces of the upper box 1 and the lower box 2 are hinged by a hinge 12. The upper box 1 and the lower box 2 are both provided with a placement cavity 13. The BD disc 3 is placed in the placement cavity 13. The placement cavity 13 on the lower box 2 is provided with a claw 14. The BD disc 3 is locked on the claw 14. The claw 14 can be elastically deformed to facilitate the placement, fixing and removal of the BD disc 3.
[0024] The upper box 1 has symmetrical through notches 15 on the front side, and a horizontal slot 16 is provided in the middle of the upper box 1 corresponding to the through notch 15. The horizontal slot 16 is provided with a matching card block 17.
[0025] A pull block 18 is fixedly connected to the card block 17. The pull block 18 is a pyramidal design.
[0026] An elastic mechanism 19 is provided between the card block 17 and the lower box 2. The elastic mechanism 19 includes a step connecting rod 20 and a second spring 21.
[0027] The step connecting rod 20 moves through the lower box 2 and is fixedly connected to the locking block 17. The bottom surface of the lower box 2 is provided with a step groove 22 that is adapted to the step connecting rod 20. The second spring 21 is located in the step groove 22 and is sleeved on the outside of the step connecting rod 20.
[0028] The step connecting rod 20 and the second spring 21, together with the step groove 22, form an elastic mechanism 19, which can tighten the locking block 17 and keep the locking block 17 rotatable. Thus, the locking block 17 can penetrate the upper box 1 through the through notch 15, and the locking block 17 can limit the upper box 1 through the transverse groove 16, so that the upper box 1 is closed, effectively preventing the elastic buckle from deforming and loosening after a collision.
[0029] The working principle of this utility model is as follows:
[0030] In use, the BD disc is placed in the placement cavity 13 and locked onto the claw 14. The locking block 17 is rotated so that it aligns with the through notch 15. At this time, the upper housing 1 is closed by the hinge 12. The locking block 17 is now located inside the through notch 15. The locking block 17 is further pulled outward by the pull block 18 and rotated so that it aligns with the horizontal slot 16. The pull block 18 is then released, and the step connecting rod 20 pulls the locking block 17 back under the action of the second spring 21, so that the locking block 17 is locked into the horizontal slot 16, thereby fixing the upper housing 1 and completing the storage of the BD disc.
[0031] Arc-shaped guards 6 are provided at the four corners of the lower housing 2. The guide rods 5 and guide sleeves 4 work together to guide the movement, while the support rods 7 provide auxiliary support. When the support rods 7 are supporting, the first spring 11 and the crossbar 10 can limit the slider 8 to the middle position of the slide groove 9. Thus, when it falls, the arc-shaped guards 6 can buffer the impact and prevent the sharp corners of the BD disc box from falling directly and causing damage.
[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
