Abstract

The utility model relates to a gradient measuring ruler which measures the inclination. The utility model is characterized in that a ruler body is made up of the plastic, a curved level tube and a curved scale are arranged on the ruler body, and meanwhile a comparison table of the angle, the inclination, the levelness and the verticality are also arranged on the ruler body. When the gradient measuring ruler is used to measure the measured surface, the user can know whether the measured surface is level or vertical or not, and meanwhile the particular number value of the angle and the length of slant inclination in the range of 0 DEG to 90 DEG can be measured. The use is very convenient.

Description

Gradient measuring ruler

The utility model relates to surveying instrument, is a kind ofly to fill liquid and leave bubble in airtight container, to measure the instrument of degree of tilt.

At present, the surveyor's staff of measuring degree of tilt has straight surveyor's staff and frame level, and they are embedded with the scale mark that is carved with on straight level tube, the chi body for contrast usefulness and form by the chi body that usefulness wood, iron or aluminium are made in the chi body.This straight surveyor's staff is only limited to levelness or the length of measuring on direction of testee; Frame level has two mutually perpendicular alignment measurement faces, the levelness (verticality) of energy measurement testee on level and vertical both direction.When measuring, this two kinds of surveyor's staffs (instrument) only know whether level or vertical of testee, can not know directly how many degree of tilt of this testee has, so function singleness, use inconvenience, particularly in building trade, because not convenient, survey instrument intuitively, the build labourer is when building the slope, can only make rough measure with above-mentioned surveyor's staff (instrument), estimate its gradient then by rule of thumb or connect with the letter of digital scale mode to try to achieve, precision is not high.And the chi body complex manufacturing technology of these two kinds of surveyor's staffs, especially wooden chi body paints until the surface from blanking, rough, refining, polishing, raggle, needs through tens procedures, and in addition, irony chi body weight is heavier, and inconvenience is carried, and then price is more expensive for aluminium matter chi body.

The utility model provides a kind of levelness and verticality of both energy measurements testee, and the surveyor's staff on arbitrarily angled or slope between 0 °～90 ° of energy measurements, and above-mentioned wood, iron, aluminum chi body have been overcome in technology, weight, the deficiency of aspects such as price at one stroke.

Task of the present utility model realizes as follows: the chi body is designed to have the special-shaped chi body of a collimation measurement face, can make triangle, semicircle or shape such as trapezoidal, a leg-of-mutton limit, semicircular base and trapezoidal base are the alignment measurement face; Have an arc groove on the chi body, wherein be embedded with the arc level tube, the chi body two sides at arc groove place are provided with and match, have a transparent arc-shaped window, meter full scale with chi body arc groove size is 0 °～90 ° curved scale scale.When utilizing this Gradient measuring ruler to measure, the alignment measurement face of chi is placed tested object plane, the angle of bubble stops is the angle of tested surface in the level tube, and when tested surface was in horizontality, bubble was 0 ° of position, and when being in plumbness, bubble is 90 ° of positions.

This Gradient measuring ruler forms with plastic mould pressing, and the central angle of chi body arc slot length correspondence is 105 °～120 °, and the central angle of arc level tube length correspondence is 95 °～110 °, and promptly the length of the length guide body arc groove of arc level tube is short slightly.The external diameter of the arc bubble pipe also width of guide body arc groove is slightly little, like this, the arc level tube can be embedded in the chi body arc groove with loose distribution structure.The curved scale scale is equipped with in arc groove both sides on the chi body.

In addition, on this Gradient measuring ruler body, can be provided with long, the vertical long table of comparisons of gradient, angle, hypotenuse and level, can check on this table of comparisons of chi body immediately by measured angle, gradient that corresponding hypotenuse is long, level is long or vertical length.

The utility model has the advantages that the arbitrarily angled or gradient that can measure easily between 0 °～90 ° of tested surfaces, and can find in the table of comparisons of chi body directly that corresponding hypotenuse is long, the horizontal length of side or vertical edges length.And, because of the chi body and function plastic mould pressing of this Gradient measuring ruler forms,, being suitable for producing in enormous quantities so technology is simple, constant product quality simultaneously, also has lightly nimble, cheap characteristics.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a graduated scale of the present utility model.

Fig. 3 is the attached table of comparisons that is affixed on the chi body.

Fig. 4 is the structural representation of another kind of pattern of the present utility model-semicircle Gradient measuring ruler.

Embodiment of the present utility model as shown in drawings.Among Fig. 1,1 is trapezoidal chi body made of plastic, has an arc groove 2 on this chi body, wherein is embedded with arc level tube 3, and the central angle of arc groove 2 length correspondences is 110 ° in the present embodiment, and width is 7mm; The central angle of arc level tube 3 length correspondences is 105 °, and external diameter is φ 5.5mm, makes the length of arc level tube 3 lack 0.5～1 millimeter than the length of arc groove 2.The two sides of arc groove 2 are stained with curved scale scale 4 on chi body 1, it is the arc transparent window 5 of 5mm that there is a width these graduated scale 4 middle parts, 0 °～90 ° scale mark 6 is carved with on camber line top on the transparent window 5, levelness, verticality and gradient scale mark are carved with in following camber line bottom, make with this scale value also can record corresponding gradient when recording certain angle.On chi body 1, also be pasted with the table of comparisons 7, can on this table of comparisons 7, find the corresponding length of side according to angle that records or gradient.8 is bubble among Fig. 1.
