Abstract

The utility model relates to a T-square, which comprises a fixed ruler and a main ruler fixed on the fixed ruler, the main ruler is provided with a movable ruler, two first slide ways are respectivelyarranged along the length direction of the main ruler on both sides of the main ruler, the upper end of the movable ruler is provided with a socket matched with the main ruler, a slider matched withthe first slide ways is arranged in the socket, and two second slide ways are respectively arranged along the length direction of the fixed ruler on both sides of the fixed ruler. The T-square can beconveniently used, and can quickly draw lines with different inclinations, thus increasing the drawing speed; after use, the movable ruler can be slid out of the first slide ways of the main ruler, and is then connected with the second slide ways of the fixed ruler, at the moment, the main ruler is parallel with the movable ruler, and thereby carrying is convenient.

Description

A kind of T-square

Technical field

The utility model relates to a kind of drawing instrument, specifically, relates to a kind of drawing T-square.

Background technology

T-square, claim T shape chi again, it is " fourth " font ruler that an end is provided with crosspiece, constitute by mutually perpendicular chi head and blade, T-square is used very extensive in various designing and mappings, in use, T-square can be used with drawing instruments such as set square, protractors, thereby can draw the straight line of various different angles as requested.

Present employed T-square is very convenient when drawing horizontal line and parallel lines, but when drawing vertical line, parallax and proportional segment, must be used with drawing instruments such as set square, engineer's scale or protractors, the various different straight lines that require just can draw, the T-square function ratio is more single, and workload is big in drawing course, uses inconvenient, plotting speed is slow, inefficiency.

The utility model content

Problem to be solved in the utility model is at above problem, provide a kind of easy to use, drawing is fast, can draw the lines of differing tilt angles, portable T-square fast.

For addressing the above problem, the technical scheme that the utility model adopted is: a kind of T-square, comprise fixed ruler and the main scale of fixedlying connected with fixed ruler, described main scale is provided with moving chi, the both sides of described main scale are respectively arranged with first chute along the length direction of main scale, described moving chi upper end is provided with the groove that matches with main scale, is provided with the slide block that matches with first chute in the described groove.

A kind of concrete prioritization scheme, the both sides of described fixed ruler are respectively arranged with second chute along the length direction of fixed ruler.

A kind of concrete prioritization scheme, described moving chi bottom is connected with ruler.

A kind of concrete prioritization scheme, described moving chi bottom is provided with T type link slot, and described ruler is provided with the connector that matches with T type link slot.

A kind of concrete prioritization scheme, described ruler is provided with the length groove.

A kind of concrete prioritization scheme is respectively arranged with the length groove on described main scale and the moving chi.

The utility model is taked above technical scheme, have the following advantages: in use, can be by the main scale horizontal line that draws, draw and the perpendicular vertical curve of horizontal line by moving chi, moving chi can slide at the length direction of main scale upper edge main scale, so, can will move the position that chi slides into needs setting-out as required, then straight line is drawn, moving chi bottom is provided with ruler, and ruler can slide by the length direction along moving chi in T type link slot, and ruler can rotate around connector, so, can be as required with ruler along T type link slot to lower slider, rotate around connector then, draw by the straight line of ruler differing tilt angles, also ruler can be skidded off independent use in T type link slot, this T-square is easy to use, can draw out the lines of different angle fast, has improved the speed of drawing, after finishing using, can in first chute of main scale, skid off moving chi, will move chi then and be connected, at this moment with second chute of fixed ruler, main scale and moving chi are parallel to each other, and are convenient for carrying.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Accompanying drawing 1 is the structural representation of T-square among the utility model embodiment;

Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to view;

Accompanying drawing 3 is that the C-C of accompanying drawing 2 is to view;

Accompanying drawing 4 is the structural representation of ruler among the utility model embodiment;

Accompanying drawing 5 is that the B-B of accompanying drawing 1 is to view.

Among the figure: the 1-fixed ruler; 11-second chute; The 2-main scale; 21-first chute; 3-moves chi; The 31-slide block; 32-T type link slot; The 4-ruler; The 41-connector.

The specific embodiment

Embodiment: as shown in Figure 1, a kind of T-square comprises fixed ruler 1 and the main scale 2 of fixedlying connected with fixed ruler 1, and fixed ruler 1 is vertical mutually with main scale 2, and main scale 2 is provided with moving chi 3, is respectively arranged with the length groove on main scale 2 and the moving chi 3.

Shown in accompanying drawing 2, accompanying drawing 3, the both sides of main scale 2 are respectively arranged with first chute 21 along the length direction of main scale 2, moving chi 3 upper ends are provided with the groove that matches with main scale 2, be provided with the slide block 31 that matches with first chute 21 in the groove, the bottom of moving chi 3 is provided with T type link slot 32 along the length direction of moving chi 3, ruler 4 is provided with the connector 41 that matches with T type link slot 32, connector 41 comprises the connecting axle that an end is fixedlyed connected with ruler 4, and the other end of connecting axle is fixedly connected with terminal pad.

As shown in Figure 4, ruler 4 is provided with the length groove, and the profile of terminal pad is circular disk.

As shown in Figure 5, the both sides of fixed ruler 1 are respectively arranged with second chute 11 along the length direction of fixed ruler 1.

In use, can be by main scale 2 horizontal line that draws, draw and the perpendicular vertical curve of horizontal line by moving chi 3, moving chi 3 can slide at the length direction of main scale 2 upper edge main scales 2, so, can the position that chi 3 slides into needs setting-out will be moved as required, then straight line is drawn, moving chi 3 bottoms are provided with ruler 4, ruler 4 can slide by the length direction along moving chi 3 in T type link slot 32, and ruler 4 can rotate around connector 41, so, can be as required with ruler 4 along T type link slot 32 to lower slider, rotate around connector 41 then, draw by the straight line of ruler 4 again, also ruler 4 can be skidded off independent use in T type link slot 32 differing tilt angles.

After finishing using, can in first chute 21 of main scale 2, skid off moving chi 3, will move chi 3 then and be connected with second chute 11 of fixed ruler 1, at this moment, main scale 2 is parallel to each other with moving chi 3, is convenient for carrying.
