Abstract

The utility model discloses a multi-purpose active bare L-square ruler, comprising a fiducial L-square ruler and an active L-square ruler which are intersectant. A moving button is arranged at the intersecting point of the two L-square rulers, and makes the two L-square rulers relative move or fix. The utility model is easy to learn and manufacture, having the advantages of high speed and high precision.

Description

Multi-purpose active bare L-square rule

The utility model relates to a kind of movable square of using more, belongs to the stationery class.

Use present monolithic square to draw the grid of all size, need make two bites at a cherry, speed is slow and be easy to generate error, draws form and also need retouch out earlier each point, and is very inconvenient; As with two square draw squares, hand will be pinned two squares, is moved easily between chi and the chi, produces error.

The purpose of this utility model provides and can draw fast, amplifies various forms, grid and other pattern uses movable square more.

In order to achieve the above object, the utility model is to realize like this.It utilizes relatively moving of two squares to produce differ in size square, and square can amplify nine palace lattice, draws various forms etc. fast.It is intersected by benchmark square and mobile square and forms, has in the intersection of two chis in conjunction with them and mobile the turning round that it relatively moved or fix.

The utility model also has, and on the benchmark square dovetail groove is arranged, and trapezoidal strip hole is arranged on the mobile square, moves to turn round in dovetail groove and trapezoidal strip hole and removable.

The utility model is all right, moves to turn round to be " ten " font, is trapezoidal horizontal stripe and cross section by the cross section and is trapezoidal vertical bar and forms, and horizontal stripe is arranged in trapezoidal strip hole, and vertical bar is arranged in dovetail groove.

It compared with prior art, advantage such as it is fast to have render speed, accurate, easy to learn, manufacture easily.

Fig. 1 is many structure charts with movable square;

Fig. 2 is many with movable square A-A ' cutaway view;

Fig. 3 is many with movable square B-B ' cutaway view.

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1, 2, 3, dovetail groove 5 is arranged on benchmark square 1, trapezoidal strip hole 4 is arranged on the mobile square 3; Move and to turn round 2 and be " ten " font, by the cross section is that trapezoidal horizontal stripe 6 and cross section are trapezoidal vertical bar 7 and form, horizontal stripe 6 is arranged in trapezoidal strip hole 4, and the cross sectional shape of the cross sectional shape of horizontal stripe 6 and strip hole 4 matches, and makes horizontal stripe 6 direction along the hole move and can not swing in strip hole 4; Equally, vertical bar 7 is arranged in dovetail groove 5, and their cross sectional shape matches, and makes vertical bar 7 move and can not swing along the groove direction in groove 5; It is 6 fixing with vertical bar 7 to grow crosswise.The utility model can also adopt other scheme, for example has groove on two squares, has the hole in groove, and the bolt in conjunction with two squares is arranged in groove, turns bolt and can make relatively moving of it or fixing.

Claims

1, a kind ofly many use movable square, it is characterized in that: it is intersected by benchmark square 1 and mobile square 3 and forms, have in the intersection of two squares in conjunction with they and it is relatively moved or fix mobilely turn round 2.

2, according to claim 1ly many use movable square, it is characterized in that: dovetail groove 5 is arranged on the benchmark square 1, trapezoidal strip hole 4 is arranged on the mobile square 3, mobilely turn round 2 in dovetail groove 5 and trapezoidal strip hole 4 and removable.

3, according to claim 1 and 2ly many use movable square, it is characterized in that: mobilely turn round 2 and be " ten " font, be trapezoidal horizontal stripe 6 and cross section by the cross section and be trapezoidal vertical bar 7 and form.
