Abstract
The utility model discloses a parallel line drawing tool, which comprises a T-square and a ruler. The T-square comprises a main scale and an auxiliary scale, wherein the main scale is provided with a slide groove in parallel to the main scale, the auxiliary scale is provided with a roller in a rotating way, one end of the ruler is provided with a bulge which is arranged in the slide groove in a sliding way, and a clamping sleeve is jacketed on the bulge. The utility model can accurately draw parallel lines with any width, has simple structure, and facilitates the teaching of teachers.
Description
Technical field
The utility model relates to a kind of drawing instrument, relates in particular to a kind of parallel lines drawing instrument that can conveniently draw parallel lines that is used on the blackboard.
Background technology
The teacher runs into and need draw parallel lines through regular meeting during writing process on blackboard; as the matts of mathematics mapping, staff, Chinese character and the writing lattice of blackboard newspaper etc.; yet ordinary circumstance teacher only relies on a ruler to draw with the sensation of oneself; the parallel lines error of drawing out like this is very big; lack aesthetic feeling, also can influence teaching effect of teachers sometimes.
The utility model content
Technical problem to be solved in the utility model provides a kind of parallel lines drawing instrument, and this drawing instrument can be drawn out the parallel lines of any width accurately, and is simple in structure, makes things convenient for teacher's teaching.
For solving the problems of the technologies described above, the technical solution of the utility model is: the parallel lines drawing instrument comprises: T-square, described T-square comprise main scale and secondary chi, and described main scale is provided with the chute parallel with main scale; Ruler, described ruler is slidingly mounted in the chute of described main scale.
As a kind of improvement, an end of described ruler is provided with the projection that is slidingly mounted in the described chute, is set with gripping sleeve on the described projection.
Improve as another kind, be rotatablely equipped with roller on the described secondary chi.
Owing to adopted technique scheme, effect of the present utility model is: because described parallel lines drawing instrument comprises: T-square, described T-square comprise main scale and secondary chi, and described main scale is provided with the chute parallel with main scale; Ruler, described ruler is slidingly mounted in the chute of described main scale, therefore just can will slide in the chute of described ruler on described main scale, thereby draw out parallel lines, just can determine the width of parallel lines according to the scale on the described main scale, thereby guarantee the parallel lines of drawing out any width accurately, simple in structure, make things convenient for teacher's teaching.
Again because an end of described ruler is provided with the projection that is slidingly mounted in the described chute, be set with gripping sleeve on the described projection, therefore gripping sleeve can be taken off when not needing to draw parallel lines, described ruler can use separately again, makes things convenient for teacher's teaching.
Again owing to be rotatablely equipped with roller on the described secondary chi, therefore the secondary chi of described T-square is positioned over the top edge of blackboard, described roller just can roll on the blackboard top edge, so just can promote described T-square and move, the parallel lines that convenient drafting is long along the blackboard top edge.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the cutaway view of the utility model embodiment at the A-A place;
In the accompanying drawing: 1. T-square; 11. secondary chi; 12. main scale; 13. chute; 2. ruler; 21. projection; 3. roller; 4. gripping sleeve.
The specific embodiment
A kind of parallel lines drawing instrument, as depicted in figs. 1 and 2, it comprises T-square 1 and ruler 2, described T-square 1 comprises main scale 12 and secondary chi 11, described main scale 12 is provided with the chute 13 parallel with main scale 12, be rotatablely equipped with two rollers 3 on the described secondary chi 11, described roller 3 can place the top edge of blackboard and roll in the above, described ruler 2 one ends are provided with and are slidingly mounted on square protruding 21 in the chute 13, be set with a gripping sleeve 4 on described protruding 21, described gripping sleeve 4 can be the rubber material, and described ruler 2 can slide in chute 13, thereby draws out parallel lines.
Operation principle of the present utility model is: the roller 3 on the secondary chi 11 is placed the blackboard top edge, promoting ruler 2 slides its relative T-square 1, and scale is arranged on the main scale 12 of described T-square 1, therefore just can draw out the parallel lines of any width, and the roller 3 on the secondary chi 11 can roll on the top edge of blackboard, whole drawing instrument is moved on blackboard, the long parallel lines of being convenient to draw, when not needing to draw parallel lines, just gripping sleeve 4 can be taken off, use separately thereby take off ruler 2, make things convenient for teacher's teaching.
