Description
Technical field
The utility model relates to a kind of books protection instrument, is specifically related to a kind of protective sleeve that is used to avoid book angle fold.
Background technology
Books are that people learn important instrument.People are to use cover in order to protect books, but existing cover function singleness; people's use needs can not have been satisfied; for example: existing cover does not have the function at protection book angle, can not prevent that the book angle from fold taking place, curl, and the book angle of books is polished or comes off.
The utility model content
The purpose of this utility model is, provides a kind of book angle wrinkle resistant protective sleeve, solves above technical problem.
The technical problem that the utility model solved can realize by the following technical solutions:
The wrinkle resistant protective sleeve in book angle, comprise the protective sleeve that top and bottom are triangular in shape, dug triangular groove in the described protective sleeve, the hypotenuse of described triangular groove overlaps with the hypotenuse of described protective sleeve, it is characterized in that, be provided with a leg-of-mutton active clapboard that can in described triangular groove, move up and down in the described triangular groove, be fixed with at least one spring between the upper surface of described active clapboard and described triangular groove; The wrinkle resistant protective sleeve in described book angle also comprises a positioning rod, and the end of described backstay and described active clapboard are fixed, and described backstay passes the upper surface of triangular groove, stretches out in protective sleeve.
Be fixed with three springs between the upper surface of described active clapboard and described triangular groove, three springs are one " product " font, are distributed in around the described backstay.
Be the holding sheet at clamping book angle between the lower surface of active clapboard and triangular groove, need only during use by being pulled upwardly backstay, make holding sheet have enough spaces that the book angle is clamped, put down backstay then, under the effect of spring, active clapboard is flat to weigh down the corners of the book, can realize the wrinkle resistant effect in book angle like this, also do not influence moving of books, the gross weight of increase also seldom, it is extremely convenient to use.
Described protective sleeve comprises the wooden layer of being made by wood in the outside, the plastic layer that the inboard is made of plastics.The utility model structure is smaller and more exquisite, drops in use easily and loses on the ground or because of carelessness, if the protective sleeve list is made of plastics; be easy to fragmentation, working life is not long, and the protective sleeve list is made by wooden; may be because the carelessness in the manufacturing process; cause triangle body groove inside coarse, jagged, not only do not play wrinkle resistant effect, the book angle that is placed in the triangular groove also may be wrinkling; even scratch; plastics are compared wood, and material is more smooth, and quality is more soft.
Described protective sleeve is for adopting metal metal protection protector.Because the utility model structure is smaller and more exquisite, drops easily, the protective sleeve of metal material can guarantee quality of the present utility model.And the sound that sends when dropping is clearer and more melodious, warns easily.
Beneficial effect: owing to adopt technique scheme, the utility model can effectively be protected the book angle, have simple in structure light and handy, with low cost, easy to use, be convenient to advantage such as popularization.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, the wrinkle resistant protective sleeve in book angle comprises top and bottom protective sleeve triangular in shape 1, has dug triangular groove 2 in the protective sleeve 1, and the hypotenuse of triangular groove 2 overlaps with the hypotenuse of protective sleeve 1; Be provided with a leg-of-mutton active clapboard 3 that can in triangular groove 2, move up and down in the triangular groove 2, be fixed with at least one spring 4 between the upper surface of active clapboard 3 and triangular groove 2; Also comprise a positioning rod 5, the end of backstay 5 and active clapboard 3 are fixing, and backstay 5 passes the upper surface of triangular groove 2, stretches out in protective sleeve 1.When making the utility model, have an opening that backstay 5 can be passed on the protective sleeve 1, backstay 5 passes opening, is fixed on the active clapboard 3, preferably adopts glue to fix.Spring 4 preferably is provided with three, and three springs 4 are one " product " font, are distributed in around the backstay 5.Be arranged to said structure, stressed unanimity when active clapboard 3 clamping book angles is avoided leaving impression on the book angle.Be the holding sheet at clamping book angle between the lower surface of active clapboard 3 and triangular groove 2, need only during use by being pulled upwardly backstay 5, make holding sheet have enough spaces that the book angle is clamped, put down backstay 5 then, under the effect of spring 4, active clapboard 3 flat weighing down the corners of the book can be realized the wrinkle resistant effect in book angle like this, also do not influence moving of books, the gross weight of increase also seldom.
Protective sleeve 1 comprises the wooden layer of being made by wood in the outside, the plastic layer that the inboard is made of plastics.The utility model structure is small and exquisite, drops in use easily and loses on the ground or because of carelessness, if protective sleeve 1 singly is made of plastics; be easy to fragmentation, working life is not long, and protective sleeve 1 list is made by wooden; may be because the carelessness in the manufacturing process; cause triangle body groove 2 inner coarse, jagged, not only do not play wrinkle resistant effect, the book angle that is placed in the triangular groove 2 also may be wrinkling; even scratch; plastics are compared wood, and material is more smooth, and quality is more soft.Protective sleeve 1 is for adopting metal metal protection protector.Because the utility model structure is smaller and more exquisite, drops easily, the protective sleeve 1 of metal material can guarantee quality of the present utility model.And the sound that sends when dropping is clearer and more melodious, warns easily.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
