Description

Technical Field

[0001] This utility model relates to the field of data optical disc storage technology, specifically to a scratch-resistant protective cover for data optical discs. Background Technology

[0002] With the rapid development of digital information technology, data optical discs, as an important information storage medium, are widely used in data backup, multimedia file storage, and software distribution due to their moderate capacity, low cost, portability, and ease of use. However, the physical structure of data optical discs is relatively fragile, especially their surface, which is highly susceptible to scratches and impacts. Once the disc surface is scratched or damaged, data reading failure is highly likely, seriously affecting data integrity and security. Therefore, how to effectively protect data optical discs and prevent them from being damaged during storage and transportation has become an urgent problem to be solved in the field of storage media protection.

[0003] Most existing data optical disc protective sleeves adopt a simple box-like design, mainly encasing the disc in a closed shell. Some sleeves achieve positioning by clamping the disc through a central hole or simply securing the disc's edges. However, these designs generally have the following shortcomings: First, the top and bottom surfaces of the disc are usually in direct contact with the inner wall of the protective sleeve or other fixed structures, making them highly susceptible to scratches from friction and impact. Second, the clamping structure lacks elastic cushioning, making it difficult to effectively absorb impact during transportation or bumps, leading to disc displacement or uneven stress. Furthermore, the insertion and removal of the disc are not smooth enough, often increasing operational difficulty and the risk of scratches due to poor guidance. In summary, existing protective sleeves have significant room for improvement in preventing disc scratches, enhancing cushioning performance, and improving ease of operation, failing to meet users' needs for efficient and secure protection of data optical discs.

[0004] Therefore, this solution proposes a scratch-resistant protective cover for data optical discs to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a scratch-resistant protective cover for data optical discs.

[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: A scratch-resistant protective cover for a data optical disc includes a rectangular flat outer casing and a data optical disc. The front end of the outer casing has a strip-shaped insertion port for inserting the data optical disc. Several insertion holes are arranged sequentially from front to back on the left and right walls of the inner cavity of the outer casing. Each insertion hole is provided with a side clamping member. The side clamping member includes an insertion post that slides into the insertion hole, a fixing frame fixed to one side of the insertion post, and a clamping wheel fixed in the fixing frame. A top-tightening spring is provided at one side of the insertion hole. The outer side of the top-tightening spring is fixedly connected to one side of the insertion post. Each clamping wheel is dumbbell-shaped and clamps the edge of the data optical disc.

[0007] Preferably, a horizontally distributed slider is slidably engaged at the rear end of the inner cavity of the outer case, the rear edge of the data optical disc is pressed against the front end face of the slider, and a vertically distributed sliding perforation is opened at the top of the outer case. A sliding plate is slidably engaged inside the sliding perforation, and the bottom of the tail end of the sliding plate is fixedly connected to the top center of the slider.

[0008] Preferably, the rear end of the skateboard is provided with an arc-shaped spring.

[0009] Preferably, the front end of the outer box is hinged with a strip-shaped cover, and a pressing protrusion is provided on the inner end face of the strip-shaped cover. The inner end face of the pressing protrusion passes through the strip-shaped insertion port and presses against the front edge of the data optical disc.

[0010] Preferably, the pressing protrusion is made of an elastic material.

[0011] Preferably, longitudinally distributed guide rails are provided on both the left and right sides of the upper and lower cavity walls of the outer casing, and guide teeth are provided on the upper and lower sides of the left and right ends of the slide bar, with the guide teeth slidingly engaged inside the guide rails.

[0012] Preferably, guide wheels are provided on both the left and right sides of the strip-shaped insertion port, and the distance between the two guide wheels is the same as the diameter of the data optical disc.

[0013] Preferably, the strip-shaped box lid and the front end of the outer box are closed by a locking mechanism.

[0014] The beneficial effects of this utility model are reflected in: This data CD scratch-resistant protective sleeve achieves lateral clamping and positioning of the data CD by incorporating multiple sliding and adjustable side clamps on both sides of the outer casing. The clamping wheels within the side clamps feature a dumbbell-shaped design, which grips the edge of the CD while completely suspending the upper and lower surfaces of the disc, preventing direct contact with the upper and lower walls of the outer casing. This fundamentally eliminates scratches on the disc surface caused by friction or impact, greatly enhancing the protection of the CD.

[0015] Furthermore, the clamping spring provides appropriate and continuous elastic clamping force to the clamping wheels, ensuring the disc is securely fixed and also acting as a buffer against external impacts or transportation jolting, preventing the disc from shifting or being damaged due to sudden shocks. The cooperative design of the slider and slide plate ensures smooth and stable insertion and removal of the disc, and, in conjunction with the guide wheels, effectively avoids the risk of scratches on the disc edges. The elastic rebound function of the curved spring further stabilizes the disc's storage position and enhances the overall structure's shock resistance.

[0016] In summary, this protective sleeve not only achieves precise lateral clamping and positioning of the data optical disc, ensuring that the top and bottom surfaces of the disc do not come into contact with any part of the sleeve structure, thus avoiding the scratching problems common in traditional storage methods, but also effectively improves the safety and stability of the disc during transportation and daily use through its elastic clamping and cushioning design. Its compact structure and convenient operation greatly facilitate users' needs for storing and carrying data optical discs, significantly extending the disc's lifespan, and demonstrating excellent practical value and promising prospects for widespread adoption.

If the specific posture changes, the directional indicators will also change accordingly.

[0020] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.

[0021] Please refer to the instruction manual appendix. Figures 1-6 This utility model provides a scratch-resistant protective case for data optical discs. The case consists of a rectangular, flat outer casing 1, which is flat and rectangular in shape for easy carrying and storage. A strip-shaped insertion port 11 is provided at the front end of the outer casing for inserting a data optical disc 8. Multiple insertion holes 13 are arranged sequentially from front to back on the left and right walls of the inner cavity, and each insertion hole is fitted with a side clamping member 2.

[0022] Each side clamp 2 includes: Plug-in post 22: Plugs into plug hole 13, allowing for sliding adjustment of position.

[0023] Fixing bracket 23: Fixed to one end of the outer side of the plug-in post 22, providing a support structure.

[0024] Clamping roller 24: Installed inside the fixing frame 23, it is dumbbell-shaped and clamps the edge of the data optical disc 8. This structural design allows the upper and lower surfaces of the clamped data optical disc 8 to be detached from the upper and lower cavity walls inside the outer casing 1, directly avoiding contact and effectively preventing the upper and lower surfaces of the data optical disc 8 from being scratched during storage.

[0025] A clamping spring 21 is provided at one end of the inner side of the insertion hole 13. One end of the clamping spring 21 is fixed inside the insertion hole 13, and the other end is fixedly connected to one end of the inner side of the insertion post 22. It is used to provide elastic pressure to ensure that the clamping wheel 24 applies appropriate clamping force to the edge of the optical disc. This elastic design can also provide a certain buffering effect when the entire protective sleeve is bumped or transported, further ensuring the storage safety of the data optical disc 8.

[0026] At the rear end of the inner cavity of the outer casing 1, a horizontally arranged slider 3 is slidably engaged. The rear edge of the data optical disc 8 is pressed against the front end of the slider 3, which serves to press and position the rear edge of the data optical disc 8. It also serves as a sliding structure to assist in pushing the data optical disc 8 forward to achieve the export operation.

[0027] At the top of the outer casing 1, there are longitudinally distributed sliding perforations 14. A slide plate 7 is slidably fitted inside the perforations. The bottom of the tail end of the slide plate 7 is fixedly connected to the top center of the slide bar 3, which makes it easy for the user to push the slide plate 7 from the outside to drive the slide bar 3 to push. It is a component for exporting data CD 8.

[0028] The rear end of the slide plate 7 is equipped with an arc-shaped spring piece 4, which provides elastic rebound force to maintain the stable position of the optical disc. At the same time, it can also provide a certain cushioning effect when the entire protective cover is bumped or shaken during transportation, further ensuring the storage security of the data optical disc 8.

[0029] The outer case 1 has a strip-shaped cover 5 hinged to its front end. The inner end face of the cover has a pressing protrusion 51, and the whole is made of elastic material. The pressing protrusion 51 is inserted into the strip-shaped insertion port 11 and pressed against the front edge of the optical disc 8 to realize the positioning operation of the front edge of the data optical disc 8.

[0030] The strip-shaped box lid 5 and the outer box 1 are closed by a latch 52 to ensure that the protective cover is not easily opened accidentally during use.

[0031] The outer casing 1 has longitudinal guide rails 12 on both the left and right sides of the upper and lower parts of the cavity wall to guide the slider 3 to slide longitudinally. The upper and lower parts of the left and right ends of the slider 3 are provided with guide teeth 31, which cooperate with the guide rails 12 to slide, ensuring that the slider 3 moves smoothly along the rails and enhancing the stability of the positioning.

[0032] The strip-shaped insertion port 11 is equipped with guide wheels 6 on both sides. The spacing between the guide wheels 6 is consistent with the diameter of the data optical disc 8, which helps to guide the optical disc to be inserted and removed smoothly and avoids scratches.

[0033] The insertion and extraction process of the data optical disc is as follows: First, the user opens the front strip cover 5 of the protective case using the latch 52, lifts the cover, and allows the clamping protrusion 51 to pass through the strip insertion port 11 and be positioned at the front edge of the optical disc 8. At this time, the user guides the data optical disc 8 to be stored through the guide wheel 6, pushing the slide bar 3 inward. During the insertion process, the clamping wheels 24 in the several side clamping pieces 2 on both sides sequentially contact the data optical disc 8. As the disc continues to be pushed inward, the clamping wheels 24 and the fixing frame 23 drive the insertion post 22 to slide into the insertion hole 13, compressing the top spring 21. The top spring 21 then clamps the data optical disc 8. The clamping wheels 24 provide appropriate pressure through the spring 21, so that the edge of the optical disc is clamped and the upper and lower disc surfaces do not contact the cavity wall of the outer case 1, thereby achieving scratch protection. After the data optical disc 8 is fully inserted, the slide bar 3 slides to the rear end, where it is cushioned by the elasticity of the arc-shaped spring piece 4 at the rear end of the slide plate 7, keeping the optical disc in a stable position. To eject the disc, the user pushes the slide plate 7 forward, causing the slide bar 3 to slide along the guide rail 12, pushing the rear edge of the disc outward. At the same time, the guide wheel 6 guides the disc out smoothly.
