Abstract
Provided is a multifunctional scale, comprising a tri-prism body and a proportional rod inserting in the tri-prism body. Two ends of the proportional rod are respectively blocked in the tri-prism body through an annular rubber ring. The proportional rod is in the shape of a regular polygon, and each edge is provided with scales in different proportions and dimensions. The multifunctional scale is advantageous in that based on the inserted proportional rod, the multifunctional scale can be rotated at will to use scales in different proportions and dimensions; the variety of proportions is large, the use is simple, and the structure is portable, benefiting convenient and flexible use.
Description
Technical field
The utility model relates to the measurement rule, and what be specifically related to is a kind of engineer's scale that has multiple proportional sizes.
Background technology
At present; Engineer's scale relatively more commonly used is positive prismatic or triangle, and it is provided with different proportional sizes on the limit that each bar is fixed, and the proportional sizes quantity of this engineer's scale is provided with limited; The ratio kind is less; When the different ratio of needs is drawn, often need to prepare the different engineer's scale of multiple quantity, be with inconvenience for the drawing user.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and a kind of novel structure is provided, and the alternative multifunction ratio chi of multiple proportional sizes is arranged.
The utility model is realized through following technical scheme: a kind of multifunction ratio chi, by tri-prismoid and be inserted in the inner modelling bar of tri-prismoid and form, the two ends of said modelling bar are blocked in tri-prismoid through ring apron respectively.
Said modelling bar is that regular polygon constitutes, and each bar limit is provided with different proportional sizes scales, and the two ends of modelling bar laterally are provided with the groove that a circle ring apron is installed respectively.
One cylinder of said tri-prismoid is provided with the 1:1 scale graduation, and a cylinder is made as the arc cylinder, makes things convenient for grasping, on the face of side column always between 1:1 scale graduation cylinder and the arc cylinder, also is provided with even scale.
The interior post through hole that vertically offers an end to the other end near an even scale straight flange cylinder of said tri-prismoid; The face of side column always of this post through hole and tri-prismoid forms an opening; The diameter of post through hole is greater than the diameter of modelling bar; Insert in the post through hole so that modelling bar is convenient, and the A/F of said post through hole and evenly scale straight flange cylinder formation is less than the diameter dimension of modelling bar.
The post through hole can be circle or positive multiform.
The beneficial effect of the utility model embodies and is: compared with prior art, the utility model engineer's scale, the modelling bar that inserts according to its inside can rotate the different proportional sizes scale of use arbitrarily; The ratio kind is more; Use simply, structure is light, convenient, flexible use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed explanation.
Fig. 1 is the utility model overall structure sketch map.
Fig. 2 is the utility model decomposition texture sketch map.
Fig. 3 be in the utility model tri-prismoid the cross section structure sketch map.
The concrete title of each sign among the figure: 1 modelling bar, 2 tri-prismoids, 3 ring aprons, 11 grooves, 12 grooves, 21 post through holes, 22 straight flange cylinders, 23 arc cylinders, 24 1:1 scale graduation cylinders, 25 openings.
The specific embodiment
Like Fig. 1 to shown in Figure 3, a kind of multifunction ratio chi, by tri-prismoid 2 and be inserted in tri-prismoid 2 inner modelling bars 1 and form, the two ends of said modelling bar 1 are blocked in tri-prismoid 2 through ring apron 3 respectively.
Said modelling bar 1 is that regular polygon constitutes, and each bar limit is provided with different proportional sizes scales, and the two ends of modelling bar 1 laterally are provided with the groove (11,12) that a circle ring apron 3 is installed respectively.
Be made as 1:1 scale graduation cylinder 24, one cylinders on one cylinder of said tri-prismoid 2 and be made as arc cylinder 23, make things convenient for grasping, on the even scale straight flange cylinder 22 between 1:1 scale graduation cylinder 24 and the arc cylinder 23, also be provided with even scale.
The said tri-prismoid 2 interior post through holes 21 that vertically offer an end to the other end near an even scale straight flange cylinder 22; This post through hole 21 forms an opening 25 with the face of side column always 22 of tri-prismoid 2; The diameter of post through hole 21 is greater than the diameter of modelling bar 1; So that modelling bar 1 convenient the insertion in the post through hole 21, and opening 25 width of said post through hole 21 and evenly scale straight flange cylinder 22 formation are less than the diameter dimension of modelling bar 1.
Post through hole 21 can be circle or positive multiform.
Be respectively equipped with the ratio numeral of 1 ︰, 2.5,1 ︰, 5,1 ︰, 10,1 ︰, 20,1 ︰, 50,1 ︰ 100 on each side of modelling bar 1; And and the corresponding scale of ratio numeral; Modelling bar 1 can freely rotate in post through hole 21, and its two ends are blocked through ring apron respectively.
During use, only need to rotate the pairing scale graduation of modelling bar, can chart, modelling bar also can be prepared many different ratio kinds, and convenient the insertion in the tri-prismoid used.
The utility model engineer's scale ratio kind is many, can convenient, flexiblely use.
