Abstract
The present invention relates to a kind of students' work backing plate, including backing plate main body, the backing plate main body is the transparent backing plate of rectangle, and the edge of the transparent backing plate is divided into backing plate top, backing plate following, on the right of the backing plate left side and backing plate；The following left side of the backing plate is equipped with the graphometer of one, the following right side of the backing plate is equipped with 45 ° of set squares of one, the backing plate top is equipped with the first length scale line, the second length scale line is equipped on the right of the backing plate, it is additionally provided in the backing plate main body away from surveying device and sensing probe, it is described that alarm device is equipped in device away from surveying.Function of the present invention is more, and structure novel is easy to use, and effectively prevents students and cause visual impairment because of abnormal sitting posture, it is therefore prevented that deformity of spinal column influence body development and so on, many benefits are brought to students.
Description
Technical field
The present invention relates to mathematics auxiliary tool technology field more particularly to a kind of students' work backing plates.
Background technique
Operation backing plate is colored opaque plastic plate at present, and the upper front of plastic plate is equipped with clip, and clip is used to press from both sides
Operation, the front of plastic plate is used to pad to do the homework, at low cost although the plastic plate structure is simple, has a single function；And student
When doing the homework, sit up straight once for a long time, vertebra fatigue makes students slowly hunch, head as low as on homework book,
The eyes of students are seriously compromised, habitually hunch will cause the deformity of spinal column, to influence the body hair of student
It educates, brings many puzzlements to students.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of students' work backing plate.
The present invention is achieved through the following technical solutions:
A kind of students' work backing plate, including backing plate main body, the backing plate main body are the transparent backing plate of rectangle, the transparent pad
The edge of plate is divided into backing plate top, backing plate following, on the right of the backing plate left side and backing plate；
The following left side of the backing plate is equipped with the graphometer of one, and the following right side of the backing plate is equipped with 45 ° three of one
Gusset, the backing plate top are equipped with the first length scale line, are equipped with the second length scale line, the transparent pad on the right of the backing plate
The lower left of plate is equipped with rectangular through-hole, and the through-hole is adapted with the pen clip of pen cap, is equipped in the top of the transparent backing plate
Entrainment hole；
Be additionally provided in the backing plate main body away from surveying device and sensing probe, it is described that alarm device is equipped in device away from surveying, it is described away from
It surveys below device and electronics piece is installed, it is described to be switched away from survey device right side equipped with system control, it is described away from survey device and sensing probe, electronics piece one
System at.
Further, the transparent backing plate is organic glass.
Further, the front of the transparent backing plate is equipped with homework book, and the homework book is fixed on described by card circle
On entrainment hole.
Compared with prior art, the beneficial effects of the present invention are: transparent backing plate is equipped with the first length scale line and second
Length scale line, and integrate transparent backing plate, graphometer and 45 ° of set squares, it is not necessary in addition prepare graphometer, set square and
Ruler, use are easy to carry.In addition rectangular through-hole of the present invention is used to grafting pen clip, and Portable pen is convenient.The present invention is in transparent backing plate
Top be equipped with entrainment hole, convenient for pass through card circle fixed operation sheet.Mathematical formulae area sum number is printed in transparent backing plate front
Theorem area is learned, searches and reviews convenient for student.Therefore, function of the present invention is more, and structure novel is easy to use, and effectively prevents
Stop students and causes visual impairment because of abnormal sitting posture, it is therefore prevented that deformity of spinal column influence body development and so on, it gives
Students bring many benefits.
