Description

The intelligency activity chi

The utility model belongs to survey instrument, is a kind of intelligency activity chi specifically.

Existing ruler is mainly used in linear measure longimetry and draws straight line, and common tape only is used for linear measure longimetry, and these rulers are function singleness mostly.In the tabulation of drawing, often one reinstate ruler and divide set square equally.Sometimes need manyly just can finish a job to ruler, the user is brought inconvenience.Existing adjustable rule generally adopts hard ruler and the movable hard ruler formation that is slidingly connected, and its structure is not too reasonable, and stretching friction force is big, and it is big to take up room after the stretching, damage easily, and function is less, is not suitable for children and uses.

The purpose of this utility model is to provide a kind of intelligency activity chi at the deficiencies in the prior art, and it is simple in structure, compact, and is easy to use, and adjustable rule moves flexibly, and is not fragile, and function is more, is specially adapted to children and uses.

The purpose of this utility model is achieved by the following technical solution: a kind of intelligency activity chi, comprise fixedly ruler, adjustable rule and vernier, it is characterized in that the described long strip-board shape adjustable rule base that fixedly is provided with above the ruler, in the middle of the adjustable rule base, have axial elongated slot, one its fixed rotating shaft and the vertical vertical roller of elongated slot respectively are set at the elongated slot two ends, described adjustable rule is the endless belt-shaped tape measure of dividing equally on two rollers that are enclosed within the elongated slot, described vernier is the driving vernier that is fastened on the adjustable rule base, be zero graduation above the plane on the driving vernier, and fixedly connected with the zero graduation place that divides tape measure equally in the bottom.

All have long recess on the described adjustable rule base front and back sides, the inboard convex edge that is provided with of driving vernier front and back sides embeds in the adjustable rule base front and back sides long recess, a surface level pointer along prolonging forward at the bottom of the driving vernier leading flank, have the numerical value observation panel on it.

Under plane on the described driving vernier, a top cover that has a long rabbet is set on the adjustable rule base top surface.

In described endless belt-shaped dividing equally a horizontal fagging is set between the tape measure levels, and is fixed on the interior front and back sides of adjustable rule base elongated slot.

Also be provided with in described driving vernier both sides and select the number vernier, its shape and driving vernier are basic identical, and are fastened on the adjustable rule base, and plane has tape measure numerical value observation panel on it.

The utility model compared with prior art has many advantages and good effect: the utility model organically is combined as a whole ruler and adjustable rule, because adjustable rule is the endless belt-shaped tape measure of dividing equally, turn round in the rolling friction mode by the driving vernier drive that links to each other with tape measure, simple in structure, compact, adjustable rule moves flexibly, and is not fragile; With an alternative ruler of ruler, divide set square equally, work such as finish linear measure longimetry, draw a diagram, and can also realize other functions, as: the calculation reason that can intuitively disclose plus-minus method, can help the pupil to learn number sequence (positive sequence, inverted order), study 10 is with interior plus-minus method and gather the carry addition and 20 of 10 methods with interior subtraction.Select the number vernier can assist children to select number, calculating.Can also be used for drawing, it can be on the straight line of finishing divides according to required length and cuts, and removes the trouble of secondary measurement from.It still is that the student learns sketch, estimates the good assistant of ratio, and it can estimate out the accurate ratio of object exactly, and ratio data directly occurs.Both energy measurement length directly represented ratio, can draw straight line again, can also computational mathematics topic, carry very conveniently, be specially adapted to children and use, be the good assistant that the student learns.In addition, can make large-scale teaching aid, teacher can impart knowledge to students intuitively with the intelligency activity chi, and teaching efficiency is good, and the student is acceptant.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Referring to Fig. 1-Fig. 3, a kind of intelligency activity chi, fixedly be provided with above the ruler 1 width than fixing ruler 1 the identical long strip-board shape adjustable rule base 5 of narrow and length and fixing ruler 1, on adjustable rule base 5 front and back sides, all have long recess, the centre has axial elongated slot, vertically vertical roller 9 of one its fixed rotating shaft and elongated slot respectively is set at the elongated slot two ends, a top cover 6 that has a long rabbet is set on its end face.There is an endless belt-shaped tape measure 3 of dividing equally to be enclosed within on the two interior rollers 9 of elongated slot.Divide equally a horizontal fagging 8 is set between tape measure 3 levels, and be fixed on the front and back sides in adjustable rule base 5 elongated slots.Vernier is the driving vernier 4 that is fastened on the adjustable rule base, be zero graduation above the plane on the driving vernier 4, and bottom protrusion is fixedlyed connected with the zero graduation place that divides tape measure 3 equally.The inboard convex edge that is provided with of driving vernier 4 front and back sides embeds in the adjustable rule base 5 front and back sides long recess 7, a surface level pointer along prolonging forward at the bottom of driving vernier 4 leading flanks, has the numerical value observation panel on it.Along also a surface level pointer that extends back being set, have the numerical value observation panel on it at the bottom of driving vernier 4 trailing flanks.Also be provided with in described driving vernier 4 both sides and select number vernier 2, its shape and driving vernier 4 are basic identical, and are fastened on the adjustable rule base 5, and plane has tape measure 3 numerical value observation panels on it.

Blade is made by plastics (transparent or opaque), and fixedly ruler is that base is same as general ruler, has scale on long limit, one or both sides.Adjustable rule base 5 and top cover 6 also can be made into integrative-structure.It is the front and back of axis of symmetry or symmetrical structure up and down that whole ruler can be made into fixing ruler 1 axis.Dividing tape measure 3 equally and make for soft plastic or leather, is zero graduation (" 0 ") in the middle of it, and left and right sides scale is ascending to be symmetrical arranged, and goes up the driving vernier 4 that connects at zero graduation (" 0 ") and makes the tape measure 3 that moves about measure accurate data with its move left and right.The number vernier 2 that selects of driving vernier 4 both sides can be used for selecting number, calculating.
