Abstract

The utility model relates to a protective sleeve for CDs, which is composed of a circular cover body and a shielding sheet, wherein, the centers of the cover body and the shielding sheet are provided with symmetrical circular holes. The surface is provided with a fan-shaped opening. The opposite side of the fan-shaped opening is provided with an arc-shaped slip hook thereof. In addition, convex wall whose top end is concave inwards is arranged at the circumference roundly. While the opposite side of the fan-shaped opening of the shielding sheet is provided with a notch. Thus, a convex sheet which is bended downwards is formed. The convex sheet can be extended and exposed at an arc-shaped slip groove after the shielding sheet and the cover body are overlapped. The opening and the closing of the fan-shaped opening of the cover body are formed by the slippage of the convex sheet. When the protective sleeve for CDs is used, the convex sheet is pulled so that the CD is exposed at the fan-shaped opening of the cover body for a CD machine to read data.

Description

The CD protecting cover

The utility model relates to a kind of CD protecting cover, refers to a kind of CD dish that supplies to preserve especially, and when use, does not need to take via hand, to prevent CD dish scratch or stained protective sleeve.

Because scientific-technical progress; the storage of data is replaced by the CD dish in a large number; because of CD coils except storing mass data; Shang Kecun make video recording picture, figure and sound; and it is made based on the CD dish with extremely precise and tiny digital technology; its surface is once suffer stained or scratch; to make data, image or audio distortions; therefore the CD dish all lies against in the box body; reaching the protection effect, but when the user took the CD dish with hand, unavoidable finger can touch the surface of CD dish; and, also make the scratch of CD dish because of colliding his thing easily in putting into the CD player process.

Fundamental purpose of the present utility model; be to provide a kind of CD simple in structure dish protective sleeve; formed by a circular lid and matte; be provided with the circular hole of symmetry in the central authorities of this lid and matte; and establish the suitable height and the inside prominent wall of stubborn folding in the periphery ring of lid; after making this matte and lid stacked, supply the prominent wall of CD rim lid to be inserted in, and reach protective effect.

Another purpose of the present utility model is to provide a kind of CD protecting cover that need not take and only promptly be can read by the protective sleeve opening part.It is in this lid and matte surface one side; be respectively equipped with fan-shaped opening; wherein; the opposite side of the fan-shaped opening of lid is provided with the sliding ditch of an arcuation; the fan-shaped opening opposite side of matte then is provided with a tab; make matte and lid when stacked; this tab is stretched in the sliding ditch of arc and is slided along sliding ditch; to constitute the keying of the fan-shaped opening of lid; and can when using, protective sleeve and CD dish be placed CD player, make the light read element read the data of CD dish by fan-shaped opening; and do not need to take via hand, to prevent the stained of CD dish.

CD protecting cover of the present utility model comprises a lid, it is characterized in that: also comprise a circular matte;

Described lid, be the circle sheet shape, its central authorities are provided with a circular hole, be provided with a fan-shaped opening in a surperficial side, the opposite side of fan-shaped opening is provided with the sliding ditch of an arcuation, and its periphery then is provided with the prominent wall of suitable height, and prominent wall forms a breach in fan-shaped opening part, and the apical margin of prominent wall is inwardly stubborn folding shape, constitutes a surface level;

Described circular matte is stacked and placed on the lid inner peripheral surface, and its central authorities are provided with the center hole with lid circular hole equity, and a surperficial side is provided with a fan-shaped opening, and in shape opening of opposite side cutting of opening, forms one and bend slidably tab downwards;

Matte is mutually stacked with lid, constitutes a body.

Described CD protecting cover is characterized in that, the surface level of the prominent wall of described lid periphery, and the both sides being positioned at contiguous indentation, there are respectively equipped with line of cut, are beneficial to the CD dish and are inserted in.

Conjunction with figs. and embodiment are described in detail as follows principal feature of the present utility model and novelty thereof:
