Abstract

The utility model relates to a multifunctional underlay with a square. A square type structure is used, and a bottom plate (1), a plate surface (2) and the square (3) are arranged. The plate surface (2) is superposed on the bottom plate (1) to buffer the hardness of the bottom plate (1), and the bottom plate (1) is connected with the square (3) by a switching connecting piece (4). When the utility model is used, nothing remains but to push the concave slope to move upwards by a forefinger, and the square (3) can be opened in all directions. The utility model is underlaid under the writing page of a book, a notebook and a piece of paper, the square (3) is closed, and an iron clamping sheet (11) is combined with an iron sheet (5). The writing page is compacted tightly by the square (3) to obtain the aim of rolling edge prevention for books, notebooks and paper, and smooth writing. The utility model has the advantages of reasonable design and convenient carrying and can protect the book, the notebook and the paper, a plurality of functions are combined as a whole, and the utility model is a novel multifunctional underlay.

Description

A kind of multi-functional backing plate that square is arranged

The utility model relates to a kind of student and uses backing plate, particularly a kind of multi-functional backing plate that square is arranged.

In present technology, backing plate is the articles for use that the student popularizes, and mainly adopts herd polyvinyl chloride material to make, and fills up basis and paper and writes page or leaf down, and hardness will be conducted to writing page or leaf when writing; Easily draw and decrease the page or leaf that writes; Easily write out the distortion word; The page or leaf that writes easily slides; Pen easy to wear; Easily roll up the margin that writes; Be difficult for wieling the pen; Be difficult for having write out vigour of style in writing word, be not suitable for multi-functional development need.

The purpose of this utility model is for overcoming the shortcoming of above-mentioned prior art, and a kind of multi-functional backing plate that square is arranged is provided, and the student is used the backing plate multifunction, the convenient use.

The purpose of this utility model can realize by following measure: backing plate is provided with base plate and plate face, the plate face coincides with on the base plate, there is rivet hole the edge, with tubular rivet riveted base plate and plate face, the plate face is provided with iron plate, injection mo(u)lding has the concave slope face, scale, casket, domatic, the square of open slot, iron clamp sheet nose is bumped in two rectangular laterally saturating grooves at the bottom of the casket down, permanent magnet embeds in the middle of two iron clamp sheets, four on casket is helped the edge center place respectively a laterally saturating groove, four card correspondences of casket lid snap in four saturating grooves of casket group, and the edge fit of base plate and plate face and square is provided with the folding fitting, and forefinger is scratched into concave slope towards last pulling, square can comprehensively be opened, the plate face is inserted under the page or leaf that writes, and square puts down base and the right of pushing down the page or leaf that writes, the iron plate on the iron clamp sheet energy adhesive plate face on the square, square can close tight plate face, can be used for writing, prevent book, this, the paper roll limit can reach the smoothness of writing.Concrete structure of the present utility model and embodiment are provided by the following drawings:

Fig. 1 is an axonometric drawing of the present utility model.

Fig. 2 is the profile of square.

Fig. 3 is the front schematic view of square.

Fig. 4 is the plane of iron clamp sheet.

Fig. 5 is the plane of casket lid.

Below with reference to accompanying drawing example structure of the present utility model is described in further detail:

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, backing plate is established base plate (1) and plate face (2), the available rigid plastics sheet of base plate (1) is made, the available soft plastic film of plate face (2) is made, base plate (1) combines with plate face (2), by tubular rivet (9) riveted, plate face (2) is provided with iron plate (5), by tubular rivet (9) rivet clasp, injection mo(u)lding has concave slope face (7), scale (8), casket (10), open slot (13), permanent magnet (6) and iron clamp sheet (11) are housed in the casket (10), the casket flap has casket lid (14) base plate (1) and plate face (2) to connect with the available folding fitting of square (3) (4), fitting (4) can be put on the open slot (13), fitting (4) but gold mining belongs to hinge, soft plastic film, forefinger is scratched upwards pulling of concave slope face (7), open square (3), base plate (1) and plate face (2) insert below the page or leaf that writes, square (3) is closed in the page or leaf that writes, iron clamp sheet (11) sucks iron plate (5), on the page or leaf that writes, write, book, this, paper is crimping not, can reach the smoothness of writing.

Of the present utility model simple in structure; reasonable in design; backing plate adopts chi formula structure; protected book, basis, paper effectively, carried easily, easy to use; self is independent to form centimetre and a millimeter rule; combine write, protection, the multiple function of rule be one, adapts to the different needs that require of student, is a kind of multi-functional backing plate that square is arranged.
