CN202413119U - Set square capable of being used as simple vernier caliper - Google Patents

Abstract

The utility model relates to a set square capable of being used as a simple vernier caliper. The set square comprises a main scale and an auxiliary scale, wherein a scale body of the main scale is provided with standard scale, 50-graduated vernier graduation and 20-graduated vernier graduation; a scale body of the auxiliary scale is provided with standard scale and 10-graduated vernier graduation; and a datum hole is formed at each of the beginning parts of the vernier graduations of the main scale and the auxiliary scale. The measuring principle of the vernier caliper is applied to the set square, so that the set square is simple in structure, convenient to operate, low in cost and high in practicality, is applicable to most students and people, and brings convenience to study and work.

Description

Can make the set square of simple and easy slide measure

Technical field

The utility model relates to a kind of drawing instrument, especially a kind of set square of making simple and easy slide measure.

Background technology

Slide measure is a kind of measurer of measuring length, interior external diameter, the degree of depth.Slide measure by main scale be attached to that slidable vernier two parts constitute on the main scale.Main scale is a unit with the millimeter generally, and 10,20 or 50 lattices are then arranged on the vernier, and according to the difference of lattice, slide measure can be divided into ten minutes degree slide measure, 20 fens degree slide measures, 50 fens degree slide measures etc.Two secondary movable measuring jaws are arranged on the main scale of slide measure and the vernier, are respectively interior measuring claw and external pelivimetry pawl, and interior measuring claw is commonly used to measure internal diameter, and the external pelivimetry pawl is commonly used to measure length and external diameter.

Existing slide measure structure relative complex, meticulous, cost of manufacture is higher, generally only in teaching or test, uses, and the purchase approach is school or unit group purchase mostly.For general student or individual colony, the high and purchase inconvenience of use cost.

The utility model content

In order to solve the existing slide measure problem that use cost is higher and purchase is inconvenient for general student or individual; The utility model provides a kind of set square of making simple and easy slide measure; It applies to the measuring principle of slide measure to efficiently solve the problems referred to above on the set square.

In order to realize that the technical scheme that the utility model purpose is adopted is: a kind of set square of making simple and easy slide measure; It is characterized in that: it by main scale with attach chi and constitute; The chi body of main scale is provided with the vernier graduation of master scale, 50 calibration, the vernier graduation of 20 calibration; The chi body that attaches chi is provided with the vernier graduation of master scale, 10 calibration, and main scale is equipped with datum hole with the vernier graduation section start that attaches chi.

The beneficial effect of the utility model is: the utility model applies to the measuring principle of slide measure on the set square, and is simple in structure, easy to operate, and cost is low and practical, is applicable to most of students and individual, offers convenience for study, work.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.

Fig. 1 is the utility model main scale structural representation

Fig. 2 is that the utility model attaches the chi structural representation

1-chi body, 2-master scale, 3-vernier graduation, 4-datum hole among the figure.

The specific embodiment

In Fig. 1, first embodiment shown in Figure 2; A kind of set square of making simple and easy slide measure; It is characterized in that: it by main scale with attach chi and constitute; The chi body of main scale is provided with the vernier graduation of master scale, 50 calibration, the vernier graduation of 20 calibration, and the chi body that attaches chi is provided with the vernier graduation of master scale, 10 calibration, and main scale is equipped with datum hole with the vernier graduation section start that attaches chi.

In Fig. 1, second embodiment shown in Figure 2, when needing to measure length, select main scale (or attaching chi) as dip stick according to required precision, attach chi (or main scale) as vernier.During measurement, dip stick is corresponding with the measuring object starting point zero point, and the datum hole of vernier is corresponding with the zero point of dip stick, reads length according to the vernier caliper measurement principle.

In Fig. 1, the 3rd embodiment shown in Figure 2, when needing the straight line of picture regular length, select main scale (or attaching chi) as dip stick according to required precision, attach chi (or main scale) as vernier.The datum hole of vernier is corresponding with the zero point of dip stick, and pass the datum hole starting point of drawing with pen; According to the straight length moving cursor, aim at this length graduation mark to datum hole, and pass the datum hole terminal point that draws with pen and get final product.

Claims (1)

1. the set square that can make simple and easy slide measure; It is characterized in that: it by main scale with attach chi and constitute; The chi body of main scale is provided with the vernier graduation of master scale, 50 calibration, the vernier graduation of 20 calibration; The chi body that attaches chi is provided with the vernier graduation of master scale, 10 calibration, and main scale is equipped with datum hole with the vernier graduation section start that attaches chi.
