Abstract
The utility model discloses a scheme is, a scale slidable T square, including erecting the chi, with perpendicular chi perpendicular and an adhesive transverse ruler and an at least moving scale chi. The moving scale chi can slide in transverse ruler's draw -in groove, just the scale of moving scale chi is two kind at least scales, and the one of which is the scale zero and is located the scale middle part in moving scale chi tip, another scale zero for aim at axis or symmetrical line, in order to draw symmetrical figure. The utility model discloses the beneficial effect of type is: owing to adopted the scale that can slide, when drawing, can just directly aim at size benchmark or technological standard with the zero graduation, directly measure required size, accomplish the drawing of figure line.
Description
invention field
The present invention relates to a kind of plotting equipment, particularly a kind of scale slidably T-square.
background of invention
When carrying out three-view diagram and drawing, usually to select size datum and technological datum, and the reference position of the T-square of reality is for benchmark with drawing board frame, this makes drawing personnel often need to carry out the conversion of size when drawing, therefore be necessary to design the T-square that a kind of rule can slide, when needs are drawn, just zero graduation aimed at size datum or technological datum, size required for directly measuring, can complete the drafting of figure line.
Summary of the invention
Scheme of the present utility model is, a kind of scale slidably T-square, comprises perpendicular chi, and the crossfoot that bond and at least one piece moving scale chi vertical with perpendicular chi.
Arrange draw-in groove in described crossfoot, there is rule crossfoot side;
Described at least one moving scale chi comprises dop, scale and handle, described dop is consistent with the draw-in groove size of described crossfoot, and in the middle part of dop, tapped through hole is set, holding screw is had to screw with it in through hole, when slip rule slides into precalculated position, screw holding screw with fixing slip rule, described holding screw end arranges pad and rubs in order to increase and protect crossfoot, in order to avoid be damaged, when needs shift scale chi, unclamp holding screw, hand-held handle slides to desired location;
Wherein, the feature of described crossfoot is that the first plane is higher than the second plane, when described at least one moving scale chi inserts draw-in groove and is buckled in the second plane of crossfoot, first plane of crossfoot is mutually concordant with the first plane of described at least one moving scale chi, and the second plane of crossfoot and the second plane of described at least one moving scale chi fit;
Wherein, described at least one moving scale chi, can be the rule that many engineer's scales are different;
Described rule is the conventional scale of engineer's scale 1:1, and zero point of scale is at the infall of perpendicular chi and crossfoot;
The scale of described moving scale chi is at least two kinds of scales, one be scale zero at moving scale ruler end part, another scale zero is positioned in the middle part of rule, in order to alignment axis or line of symmetry, to draw symmetric figure;
The beneficial effect of the utility model type is: owing to have employed the rule that can slide, and when needs are drawn, directly just zero graduation can be aimed at size datum or technological datum, the size required for directly measuring, complete the drafting of figure line.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
A kind of scale slidably T-square, comprises perpendicular chi 1, the crossfoot 2 that also bond vertical with perpendicular chi 1 and at least one moving scale chi 3.
Arrange draw-in groove 24 in described crossfoot 2, there is rule 21 crossfoot 2 side;
Described at least one moving scale chi 3 comprises dop 34, scale 31 and handle, described dop 34 is consistent with draw-in groove 24 size of described crossfoot, and in the middle part of dop, tapped through hole is set, holding screw is had to screw with it in through hole, when slip rule slides into precalculated position, screw holding screw with fixing slip rule, described holding screw end arranges pad and rubs in order to increase and protect crossfoot, in order to avoid be damaged, when needs shift scale chi, unclamp holding screw, hand-held handle slides to desired location;
Wherein, the feature of described crossfoot is that the first plane 22 is higher than the second plane 23, when described at least one moving scale chi 3 inserts draw-in groove 21 and is buckled in the second plane 23 of crossfoot, first plane 22 of crossfoot is mutually concordant with the first plane 32 of described at least one moving scale chi, and the second plane 23 of crossfoot fits with the second plane 33 of described at least one moving scale chi;
Wherein, described at least one moving scale chi 3, can be the rule that many engineer's scales are different;
Described rule 21 is the conventional scale of engineer's scale 1:1, and zero point of scale is at the infall of perpendicular chi and crossfoot;
The scale 31 of described moving scale chi is at least two kinds of scales, one be scale zero at moving scale ruler end part, another scale zero is positioned in the middle part of rule, in order to alignment axis or line of symmetry, to draw symmetric figure.
The foregoing is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model; The those of ordinary skill of all industry, all can shown in by specification accompanying drawing and the above and implement the utility model swimmingly; But making the equivalent variations of differentiation not departing from technical solutions of the utility model, being Equivalent embodiments of the present invention, all still belong to the technical scheme of the utility model protection.
