Abstract
The utility model relates to a vernier angle drawing ruler for mechanical drawing, comprising a basal ruler and a movable ruler whose end part is hinged with the basal ruler. One ruler at the hinge point is provided with base circle graduations, and the other ruler is provided with vernier graduations; a locking mechanism is adopted for hinging. One end of the basal ruler is hinged with one movable ruler, and alternately, either of both ends of the basal ruler is provided with one movable ruler. When straightened, the drawing ruler can be used as a long ruler; When folded, the drawing ruler can be used as a short ruler and is convenient for storage; When partly unfolded into an angle, an angle included between the two rulers being read out from the vernier graduations, the drawing ruler can be used as a protractor. The utility model can be used as a ruler for students and engineering drawing.
Description
The utility model relates to the drawing rule that a kind of mechanical drawing is used, particularly a kind of folding drawing rule.
In the prior art, the drawing rule that mechanical drawing is used is a ruler, and a kind of folding chi is also arranged in engineering survey, and the simple function of drawing straight line and measuring length is all only arranged, and purposes is limited.
The purpose of this utility model is to provide a kind of and can folds, and has the drawing rule of multiple function again.
For achieving the above object, the utility model adopts following technical proposals: the utility model is a kind of vernier angle drawing rule, and it is the same with prior art to include basic chi and at end and the hinged moving chi of basic chi.Be characterized in: at the hinged end of basic chi and moving chi, wherein on the chi basic circle calibrated dial is arranged, the vernier calibrated dial is arranged on another chi.This drawing rule can be worked as short chi and be used when amounting to, be convenient to collection; Can work as long chi when stretching uses; When being opened into certain angle, can make protractor and use, make a chi have multiple function at the angle that reads on the vernier calibrated dial between basic chi and the moving chi.
This drawing rule also can be designed at the both ends of basic chi each hinged one moving chi, and the strain when drawing to adapt to is used, and becomes long chi when stretching, can provide two angles simultaneously during bending.
Hinged between basic chi of this drawing rule and the moving chi, adopt retaining mechanism.When retaining mechanism unclamped, moving chi can rotate relative to basic chi; When retaining mechanism was locked, moving chi and basic chi relative fixed then kept the relative position between them to become a ruler or angled.Its retaining mechanism can be designed to: with the hinged basic chi of tubular rivet and moving chi, the lower end of tubular rivet is lined with bottom washers, and the upper end is lined with knob and wedge surface packing ring, and the below of knob has lug to match with circular arc wedge on the wedge surface packing ring.When the lug of knob was threaded to the low points of circular arc wedge, retaining mechanism unclamped, and moving chi can rotate relative to basic chi; When the lug of knob was threaded to the high site of circular arc wedge, retaining mechanism was pieced together tight, moving chi and basic chi relative fixed.
When basic chi of this drawing rule and moving chi are hinged, can be designed to basic chi and be in the top, moving chi is in the below, the lower limb of base chi has decurved flange, and the lower surface of moving chi has uniform small convex pillar, the end face of small convex pillar flushes with the end face of flange, basic chi is flushed with drawing with moving chi contact.Because the small convex pillar under the moving chi breaks away from chi edge and drawing, prepared Chinese ink is being stained with the chi edge and is being occurred dragging line to influence drawing quality when preventing to draw simultaneously.
The utility model compared with prior art, have following conspicuous advantage: 1. a chi has multiple function, enlarges purposes, and is convenient to collection; 2. when being used as the protractor use, because the vernier calibrated dial is arranged, its angular readings is more accurate; Can prevent when 3. drawing that prepared Chinese ink from dragging line.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the example structure schematic diagram of the utility model single action chi
Fig. 2 is the example structure schematic diagram of the two moving chis of the utility model
Fig. 3 is the structural representation of retaining mechanism
Fig. 4 is the anti-schematic diagram that drags line structure of chi
Label representative in the accompanying drawing: the moving chi 7-tubular rivet 8-wedge surface packing ring 9-lug 10-knob 11-flange 12-bottom washers 13-small convex pillar of the moving chi 5-base of 1-retaining mechanism 2-basic circle calibrated dial 3-vernier calibrated dial 4-chi 6-
An embodiment of the present utility model: referring to Fig. 1, the left end of basic chi 5 hinged is moving chi 4.Be carved with length scale made in Great Britain on the base chi, be carved with metric system length scale on the moving chi.Moving 4 and basic chi 5 between be hinged and adopt retaining mechanism 1.Center with retaining mechanism 1 is the center of circle, is carved with basic circle calibrated dial 2 on moving chi 5, and matches with basic circle calibrated dial 2 on the moving chi being carved with vernier calibrated dial 3 on the basic chi 5.Base chi 5 and moving chi 4 all adopt transparent lucite or plastics to make.
Another embodiment of the present utility model is: referring to Fig. 2, this drawing rule is that each is hinged one moving chi 4,6 at the two ends of a basic chi 5, and the hinged place, two ends is to be carved with basic circle calibrated dial 2 on moving chi 4,6 equally, and is carved with vernier calibrated dial 3 on basic chi 5.The retaining mechanism 1 of the hinged employing of moving chi 4,6 and basic chi 5 as shown in Figure 3, with tubular rivet 7 hinged basic chis 5 and moving chi 4,6, the lower end of tubular rivet 7 is lined with bottom washers 12, and the upper end is lined with knob 10 and wedge surface packing ring 8, and the below of knob 10 has lug 9 to match with circular arc wedge on the wedge surface packing ring 8.Moving chi 4,6 is to cooperate with taper surface with basic chi 5 hinged places, to guarantee positioning accuracy.Referring to Fig. 3 and Fig. 4, basic chi 5 is in the top, and moving chi 4,6 is in the below, and the lower limb of basic chi 5 has decurved flange 11, and the lower surface of moving chi 4,6 has uniform small convex pillar 13, and the end face of small convex pillar 13 flushes with the end face of flange 11.
The utility model can be used chi as what the student did one's assignment, also can make engineering drawing chi.
