Detailed description of the invention
Below, the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.
Fig. 1-Fig. 4 is an embodiment of the present utility model.As shown in the figure, what can adjust line pitch can the special picture chi of automatic shift hatching, be made up of chi plate 10-, pressing plate 20, limited block 30 ,-rubber tire 40, ratchet 41, wheel shaft 50-, turn 60, hypotenuse 11-is provided with before chi plate 10-, centre is provided with back-up block 12, both sides are provided with locating hole 16 ,-be provided with major axis cover 13-below; Has square hole 25 in the middle of described pressing plate 20, after limit be provided with short sleeve 21-, both sides are provided with ratchet 22; Chi plate 10-, pressing plate 20, rubber tire 40 and ratchet 41 are combined through series connection as a whole by described wheel shaft 50-.
Back-up block 12 upper and lower side is fixed on chi plate 10-, and top is provided with circular hole, and limited block 30 is connected by circular hole by screw 31, and the length of back-up block 12 and the diameter compatible of limited block 30 close, by rotary stopper block 30, and the height that adjustable pressing plate 20 is upspring; By trip bolt 31, limited block 30 can be fixed on back-up block 12.
Limited block 30 is designed to cylindrical, and the connected position of screw 31 is located at the centre of any line segment between limited block 30 center of circle and round edge.
Ratchet 22 is fixed in pressing plate 20 by rotating shaft 23, and ratchet 22 and rotating shaft 23 are in matched in clearance, and under gravity, pawl point swings to ratchet 41 to ratchet 22 all the time, and the rubber tire 40 be connected as a single entity with ratchet 41 can only be rotated to the direction set.
Rubber tire 40 and ratchet 41 are an entirety, and the two and wheel shaft 50-are interference fit.
Wheel shaft 50-diameter is less than the internal diameter of long inner hole of shaft sleeve 14 and short sleeve endoporus 24, and wheel shaft 50-and major axis overlap between 13-and short sleeve 21-in matched in clearance.
Pressing plate 20 (or be designed to external force be less than the elastic force of turn 60 time) when not having External Force Acting, the elasticity of turn 60 can push it to the location, below of limited block 30.
Using method:
1) chi plate 10-is placed on needs, on the figure paper of profile drawing line, to adjust the angle between setting-out limit 15 and the part outline needing profile drawing line;
2) hand pins pressing plate 20 downwards, and chi plate 10-is fixed, and another hand pen is near hypotenuse 11 setting-out in part outline;
3) Article 1 line is drawn complete, and unclamp pressing plate 20, pressing plate 20 upwards boosts by turn 60, and the ratchet 22 being positioned at pressing plate 20 both sides forces ratchet 41 to rotate, and ratchet 41 drives-and rubber tire 40 rotates, and makes chi plate 10-parallel shifted backward;
4) repeat 2) and 3) action, namely rapid drawing makes parallel and equidistant hatching;
5) unclamp screw 31-, rotation-limited block 30, can the height that pressing plate 20 is upspring be adjusted, again after trip bolt 31, according to newly-installed horizontal line spacing, the hatching with former different spacing can be drawn out.
Above-described embodiment of the present utility model is the exemplary embodiment for illustrating cited by the utility model, instead of to the restriction that embodiment of the present utility model is done.By the utility model embodiment prompting the obvious variation pattern of amplifying out be still in rights protection scope of the present utility model.
