Description

Telescopic writing surface capable of being supported on bookshelf

Technical Field

The invention relates to a telescopic writing surface capable of being supported on a bookshelf, in particular to a novel product, namely a writing surface, which can be placed on an original plane desk for use, can be used for placing books, can increase the writing area and can also be used for writing by adopting an inclined surface, and belongs to a combined device of a desktop plate and the bookshelf capable of changing the writing conditions of the plane desk.

Background

Traditional desk is the plane table, and the desktop board area is limited, to high school student, because the content of study is more, most students all put the front end of desk to books and review data, the desktop area of leaving writing like this is just very limited, writing efficiency has been influenced, narrow and small plane desktop space makes the lower of student's the curved head simultaneously, cause bow-back and myopia easily, influence healthy and image quality, it is impassable to bow for a long time to cause qi and blood, easy cerebral circulation is not enough, influence learning efficiency. If the desk is replaced in a large area, the resource waste of the existing plane desk is obviously unrealistic, and the desktop function can be upgraded only by placing a matched desktop plate combination device on the basis of the original plane desk.

The invention content is as follows:

the purpose of the invention is as follows:

the invention is designed for solving the problems, firstly, the invention solves the problem of effective utilization of the resources of the existing flat table, the desktop plate, the bookshelf and the whole table are separately designed, the bookshelf is used as a supporting device to design a set of desktop plate combination device which can be matched with the original desk for use, the desk can be placed on the original flat table for use and can move, the application range is enlarged, the function upgrade of the existing flat table is realized, and the resources of the existing flat table are effectively utilized; secondly, the problem that the plane table is not beneficial to healthy writing is solved, the supporting function of the bookshelf is utilized, the desktop plate can form an inclined surface state which accords with human engineering during writing, humpback and myopia can be prevented, and the learning efficiency is improved; thirdly, the desktop plate can extend outwards from the lower surface of the bookshelf and form an inclined plane, so that the writing area of the desktop is enlarged, the backrest of the chair can play a role, and the back of a student leans against the chair back to read and write, so that the waist fatigue can be effectively relieved; fourthly, a bookshelf is designed at the front end of the desktop plate, so that more books and data can be placed on the bookshelf; fifthly, the front end of the desktop plate is provided with a rectangular opening and an inverted L-shaped stop strip, and the desk stand can be used together with the front baffle of the bookshelf to form a book stand, so that the reading is convenient; sixthly, the desktop plate is made of transparent materials, so that the desktop plate does not need to be taken down from a desk during examination at ordinary times, the moving trouble is reduced, and seventhly, the front baffle of the bookshelf is provided with a series of transverse notches, so that the desktop plate can form inclined planes with different angles, the overall height can be improved, and the bookshelf is suitable for students with higher heights.

The technical scheme is as follows:

in order to achieve the purpose, the invention adopts the following scheme to achieve the functions:

the design area of desktop board is less than the original desk top, can keep flat and use on the original desk top, there is a space that can hold a part of desktop board below the bookshelf, the bookshelf can lean on the edge at the front end of original desk top, it is fixed with original desk top with two clamps about, a part can contract in the space below the bookshelf when the desktop board is in the planar state, the preceding baffle of bookshelf has a series of horizontal breach, the breach width is greater than desktop board thickness, and with the size of desktop board, the position corresponds mutually, desktop board one end can insert and form the support in the horizontal breach like this, under the cooperation support of original desktop, the desktop board can form the inclined plane of different angles.

One end of the desk panel is provided with an L-shaped notch, a series of vertical stop bars are arranged between the transverse notches of the front baffle of the bookshelf, the width of the horizontal stop bars is smaller than the opening width of the L-shaped notch at one end of the desk panel, the size and the position of the horizontal stop bars correspond to each other, so that one end of the desk panel can be inserted into the transverse notch of the bookshelf and then moves towards the other side after being inserted, the turning hollowed-out part of the L-shaped notch and the vertical stop bars of the bookshelf form a yin-yang fit, the desk panel cannot move up and down randomly, and the inclined plane state is relatively stable.

The front baffle of the bookshelf is provided with a series of transverse notches which are different in height, the desktop plate is inserted into the transverse notches with different heights to form different inclined plane angles, and the height of the desktop plate can be integrally improved by matching with the cushion blocks placed below the desktop plate.

One end of the desktop plate is provided with a vertical upward baffle strip which can prevent books from sliding off, a rectangular notch and an inverted L-shaped baffle strip are arranged at the position close to the L-shaped notch, the spine part at the lower end of an opened book is placed in the rectangular notch, the inverted L-shaped baffle strip can block the left side and the right side of the lower end of the book to prevent the book from being closed, and the back of the book leans against the front baffle of the bookshelf, so that a simple book stand can be formed.

The bookshelf is a bookshelf which is closed on four sides and can be used for placing books and is formed by the front baffle, the rear baffle and the side baffles, and a fixing piece which can be clamped together with the original desktop by a clamp is arranged below the side baffles.

The desktop plate is made of transparent materials, and the desk pad can be taken as a writing desk pad without being taken down in ordinary examinations.

Advantageous effects
