Abstract
The utility model relates to a kind of Multifunctional band tape drafting instrument, comprise flexible tape measure, tape measure comprises chi shell and closely coils the chi bar in chi shell, chi shell have for the flexible chi hole of chi bar, the front of chi bar is printed on the scale of measuring length, this instrument is provided with the picture circular hole entered for penholder at the starting point place of chi bar scale, the chi shell wall of chi orifice part is provided with the sharp-pointed supporting leg of end; As long as tape measure is stretched out the circle that predetermined length just can draw equal radius by this instrument, structure is not only simple but also practical, is especially applicable to building-site surveying and mapping.
Description
Technical field
The utility model relates to a kind of drafting instrument, is specifically a kind of Multifunctional band tape drafting instrument.
Background technology
At present, market is sold and variously paints sired results tool, its main structure is all that the two legs of compasses is fixed on an angle, then with pin pin leg for painting circle in the center of circle, but in some special occasions such as interlayer, paint circle or draw larger-size bowlder, the compasses of this kind of structure just cannot be finished the work, and this kind of compasses radius more thigh will be longer, therefore the compasses of some large sizes take up room very much.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provide a kind of volume little, can draw large scale circle and draw accurate Multifunctional band tape drafting instrument.
In order to solve above technical problem, the utility model provides a kind of Multifunctional band tape drafting instrument, comprise flexible tape measure, tape measure comprises chi shell and closely coils the chi bar in chi shell, chi shell have for the flexible chi hole of chi bar, the front of chi bar is printed on the scale of measuring length, and be provided with the picture circular hole entered for penholder at the starting point place of chi bar scale, the chi shell wall of chi orifice part is provided with the sharp-pointed supporting leg of end; As long as tape measure is stretched out the circle that predetermined length just can draw equal radius by this instrument, this structure is very simple and practical, is especially applicable to building-site surveying and mapping.
The technical scheme that the utility model limits further is:
Further, at the picture circular hole interpolation limited location frame of described chi bar.
Further, position-limited rack inserts penholder primarily of the tubulose that a section runs through picture circular hole and one end embeds and passes the holding screw composition inserting penholder sidewall, adjust nib exposed length and tighten holding screw can directly paint as long as paintbrush is inserted in penholder, this paintbrush being socketed with position-limited rack is very firm in painting process, there will not be and cause arc drafting to occur error, as long as holding screw can ensure that any paintbrush can insert in penholder can complete accurate drawing because rock.
Further, the tip of one end end face and described supporting leg that slotting penholder exposes the chi bar back side is in same level, and this paints bowlder to ensure, chi bar is in level, improves drafting accuracy.
Further, also comprise chi bar locking device, locking end and the chi bar of locking device keep magnetic contact, and the operating side of locking device is extended chi shell and become sliding pair with described chi hull shape, and this device is in order to fixed ruler is long, are exactly briefly to play to determine.
Further, the side of described chi shell is provided with protractor.
The beneficial effects of the utility model are: the utility model structure is simple, is easy to carry, easy to use, can draw the circle of any radius, circular arc, point cyclotomy and measuring angle, and draw accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Chi shell 1, chi bar 2, chi hole 3, inserts penholder 4, supporting leg 5, locking device 6, protractor 7, holding screw 8.
Detailed description of the invention
embodiment 1
The Multifunctional band tape drafting instrument that the present embodiment provides, as shown in Figure 1, comprise steel tape, steel tape comprises chi shell 1 and closely coils the steel ruler bar 2 in chi shell 1, chi shell 1 has for the flexible chi hole 3 of steel ruler bar 2, the front of steel ruler bar 2 is printed on the scale of measuring length, is provided with the picture circular hole entered for penholder at 0 place of steel ruler bar 2 scale, in picture circular hole, run through the slotting penholder 4 having one section of tubulose, the sidewall of slotting penholder 4 is bolted with holding screw 8; The chi shell wall of chi hole 3 oral area is provided with the sharp-pointed supporting leg of end 5; Also comprise chi bar locking device 6, locking end and the steel ruler bar 2 of locking device 6 keep magnetic contact, and the operating side of locking device 6 is extended chi shell 1 and formed sliding pair with chi shell 1, and the side of chi shell 1 is provided with protractor 7.
Using method is: suppose that user needs picture radius to be the circle of 7cm; (1) first steel ruler bar 2 is pulled out to scale 7cm place, moves locking device 6 and fix steel ruler bar 2, graduation mark corresponding to scale 7cm is just overlapped with the side in chi hole 3; (2) because the tip of inserting one end end face and supporting leg 5 that penholder 4 exposes the chi bar back side is in same level, so paintbrush to be inserted in penholder 4 and to look at straight by eye level, as long as when seeing that nib exposes the end face of slotting penholder 4, tighten the installment and debugging that holding screw 8 can complete whole drawing tool; (3) with supporting leg 5 for the center of circle, it is the circle of 7cm that paintbrush can be drawn as a radius around it.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
