Description

A kind of grafting environmental protection cover

Technical field

A kind of cover structure belongs to field of stationery, relates generally to a kind of grafting environmental protection cover.

Background technology

Cover typically refers to be made one layer of the outermost of books of ground paper, cloth, thin,tough silk, skin etc., with the development of technology, cover Generally use cloth or paper or other lightweight materials are made, and practicality is stronger, however, folding cover of the prior art subsequently needs Sticker etc. is fixed, and the problem of book angle crimping easily occurs.

Utility model content

To solve the above-mentioned problems, it is simple in structure the utility model discloses a kind of grafting environmental protection cover, consolidate without sticker Fixed, protecting effect is more preferably.

What the purpose of this utility model was realized in：

A kind of grafting environmental protection cover, including left front cover and right front cover, left front cover and right front cover are established by spine and connected, left Front cover is identical with the structure of right front cover, left front cover include face body and be arranged circumferentially in the upper hem of face body surrounding, side edgefold and under Flanging, upper hem, side edgefold and lower hem face body are established by fold line and connected, and upper hem is equipped with the first broken line and the second folding Line, the first broken line and the second broken line have a public point, the friendship of fold line where fold line where upper hem and side edgefold Point is overlapped with the public point, is provided with notch on the side edgefold, and upper hem is along after the first broken line and the second folding line Tongue is formed, the end of tongue is inserted in notch.

Further, the upper hem is identical with lower hem structure, the upper hem at the first broken line and the second broken line Stretch out to form lug, the tongue is formed after upper hem is folded by respective folded line, the both sides of lug and upper hem Joint is provided with notch, and lug forms mortise lock structure, prevents tongue from coming off.

Further, the upper end of the spine upwardly extends to form the first screening glass, and the lower end of spine is downwardly extending Second screening glass.

Further, the shape size of the first screening glass and the second screening glass is identical, and isosceles trapezoid is presented in the first screening glass, After first screening glass and the second screening glass are folded against, the inner side of spine is placed in, strengthens the protection at spine.

Further, the face body outer lateral side is covered with course label, and name is covered with the outer lateral side of side edgefold Label, applicability are stronger.

Further, fold line where the side edgefold is the first broken line and the angular bisector of the second broken line.

Further, the cover is papery cover, solid fiberboard cover or plastic cover, and feeding is various, is met different The demand of crowd.

The utility model compared with prior art, has the advantages that the utility model is simple in structure, utilizes production Technique, broken line at compacting, is folded according to broken line on upper hem or lower hem, and tongue is fixed using notch, is prevented Flanging warpage after only folding, causes cover to come off, while is also possible to prevent the curling at book angle, without chemical materials such as stickers Auxiliary is fixed, environmental and durable beneficial to the recycling in later stage, meets the needs of environmental protection production.
