Abstract
The utility model discloses a kind of four line lattice instruments of drawing, comprise bracing frame and scriber, on four angles of support frame as described above, be respectively arranged with a sucker, described sucker equates with the outer rim distance of bracing frame, described sucker be shaped as square, on described sucker, be provided with the first chalk jack, on described scriber, be provided with four the second chalk jacks, four the second chalk jacks are evenly distributed up and down, and the second chalk jack at two ends equates with the distance at scriber edge; The utility model adopts after above technical scheme, has the following advantages: simple in structure, be easy to carry; Can disposablely draw four straight lines, and ensure that the spacing between every straight line equates, setting-out speed is fast; In the time using the drawn line segment length of scriber inadequate, can continue to be connected, and be still straight line.
Description
Technical field
The utility model relates to a kind of four line lattice instruments of drawing, and belongs to teaching equipment field.
Background technology
When the Chinese phonetic alphabet, need in four line lattice, write phonetic professor, draw four line lattice on blackboard time, the existing method that draws four line lattice is: draw one by one single line according to the spacing of having measured with long ruler and chalk, complete the drafting of four line lattice; Or rule of thumb directly to carry out free-hand drafting in order saving time, to be often difficult to ensure that line-spacing is consistent.Consuming time many in drawing four line lattice, in the time that needs are drawn four lines continuously, operating difficulties, cannot ensure the regular of lines.
Utility model content
The technical problems to be solved in the utility model is for above deficiency, and a kind of four line lattice instruments of drawing are provided, and has disposable four lines that draw, and can perfectly be connected the advantage that continues setting-out.
For solving above technical problem, the utility model is by the following technical solutions: a kind of four line lattice instruments of drawing, comprise bracing frame and scriber, on four angles of support frame as described above, be respectively arranged with a sucker, described sucker equates with the outer rim distance of bracing frame, described sucker be shaped as square, on described sucker, be provided with the first chalk jack, on described scriber, be provided with four the second chalk jacks, four the second chalk jacks are evenly distributed up and down, and the second chalk jack at two ends equates with the distance at scriber edge.
The inner side of support frame as described above is provided with two chutes, and two chutes are symmetrical arranged along the center line of bracing frame.
Described scriber is arranged between two chutes.
Between described scriber and bracing frame for removably connecting.
The left and right framework of support frame as described above is respectively equipped with folding, and described folding is arranged on middle part.
Described sucker is inserted in bracing frame.
Between described sucker and bracing frame for removably connecting.
Described scriber is rectangle structure, and the second chalk jack center of circle on described scriber point-blank.
Described scriber is provided with hand-held device.
The two ends up and down of described scriber are provided with sliding bearing, and described sliding bearing is arranged in chute.
The utility model adopts after above technical scheme, compared with prior art, has the following advantages: simple in structure, be easy to carry; Can disposablely draw four straight lines, and ensure that the spacing between every straight line equates, setting-out speed is fast; In the time using the drawn line segment length of scriber inadequate, can continue to be connected, and be still straight line.
Below in conjunction with drawings and Examples, the utility model is elaborated.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of drawing four line lattice instrument in the utility model embodiment;
In figure,
1-bracing frame, 2-scriber, 3-the first chalk jack, 4-hand-held device, 5-chute, 6-the second chalk jack, 7-sliding bearing, 8-sucker, 9-folding.
Detailed description of the invention
Embodiment 1, as shown in Figure 1, a kind of four line lattice instruments of drawing, comprise bracing frame 1 and scriber 2, on four angles of bracing frame 1, are respectively arranged with a sucker 8, sucker 8 equates with the outer rim distance of bracing frame 1, sucker 8 be shaped as square, on sucker 8, be provided with the first chalk jack 3, on scriber 2, be provided with four the second chalk jacks 6, four the second chalk jacks evenly distributed and equal diameters Shang Xia 6, the second chalk jack 6 at two ends equates with the distance at scriber 2 edges.
The inner side of bracing frame 1 is provided with 5, two chutes 5 of two chutes and is symmetrical arranged along the center line of bracing frame 1.
Scriber 2 is arranged between two chutes 5.
Between scriber 2 and bracing frame 1, for removably connecting, its connected mode can be selected the connected mode such as latch closure, bolt.
The left and right framework of bracing frame 1 is respectively equipped with folding 9, and folding 9 is arranged on middle part.
Sucker 8 is inserted in bracing frame 1.
Sucker 8 removably connects with bracing frame 1, and its connected mode can be selected the connected modes such as latch closure.
Scriber 2 is rectangle structure, and second chalk jack 6 centers of circle on scriber 2 point-blank.
Scriber 2 is provided with hand-held device 4.
The two ends up and down of scriber 2 are provided with sliding bearing 7, and sliding bearing 7 is arranged in chute 5.
When use, chalk is inserted into respectively in the first chalk empty 3 and the second chalk jack 6, bracing frame 1 is placed on blackboard, draw four straight lines by mobile handsets 4; In the time that line segment distance is inadequate, by needing, near two suckers 8 junction are motionless, bracing frame 1 is taken down from blackboard, and Rotate 180 degree, then bracing frame 1 is injected to fixed sucker 8 on blackboard, be adsorbed onto on blackboard, then carry out setting-out; In the time that line segment distance is inadequate and whole drafting four line lattice have taken off completely with instrument, can first two suckers 8 on one side on bracing frame 1 be fixed to the place of chalk mark, then carries out setting-out.
The above is giving an example of the utility model preferred forms, and the part of wherein not addressing is in detail those of ordinary skill in the art's common practise.Protection domain of the present utility model is as the criterion with the content of claim, and any equivalent transformation carrying out based on technology enlightenment of the present utility model, also within protection domain of the present utility model.
