Abstract
A multifunctional measuring tape comprises a tape box, a tape wound in the tape box, a drawing needle arranged on the bottom of the tape head, a tape locking device arranged on the tape box, a circle center positioning needle arranged on the bottom of the tape box, a blind hole arranged on one side of the tape box, a spring arranged in the blind hole, a press key arranged on the upper end of the spring, and a locking block arranged on the lower end of the spring, wherein the circle center positioning needle is mounted in the blind hole by the spring and the locking hole. The drawing positioning device is improved, thus the structure of the measuring tape is subtler, and the circle or arc drawing by the measuring tape is more accurate, and the measuring tape is more convenient to operate. The measuring tape is endowed with new functions, and has higher practical value.
Description
Technical field
The utility model relates to survey instrument, is specifically related to a kind of tape measure of using more.
Background technology
Tape measure is survey instrument commonly used in the daily life, and what everybody often saw is the steel tape of building and finishing usefulness, also is one of indispensable instrument of family.Tape measure is to realize the survey instrument of retraction automatically under the elastic force effect of wind spring, and is easy to carry because its volume is little, is widely used.But tape measure still only is used as survey instrument extremely at present, is not endowed other functions, and in actual use, people tend to utilize tape measure to draw circle diagram, draw arc etc., and such technique of painting is inconvenience, out of true naturally.I use tape measure a kind of of first to file more, patent No. ZL200820036756.1, and this tape measure is operated too loaded down with trivial details in use, center of circle pilot pin need be fiddled with, and the improved place of needs is still arranged technically.
The utility model content
The utility model provides a kind of at the existing technical matters of existing tape measure and uses tape measure more, and purpose is: not only make things convenient for but also accurate with this tape measure picture circle, picture arc.
The technical solution of the utility model
A kind ofly many use tape measure, comprising: the chi box, be around in chi band in the chi box, be positioned at chi band tape head hook base the picture pin, be located at chi on the chi box and with lockly decide device, be located at the center of circle pilot pin bottom the chi box, it is characterized in that: described chi box one side is provided with blind hole; Be provided with spring in the described blind hole; Described spring upper end is provided with button, the lower end is provided with latch segment; Described center of circle pilot pin is installed in the blind hole by spring, latch segment.
Described latch segment is from vertically seeing center line and center of circle pilot pin dead in line.
Described picture pin can protrude from the tape head hook base, also can recess be set on the base, allows the base be sharp tooth for one jiao.
The beneficial effects of the utility model
The utility model makes structure more ingenious, more accurate, more convenient to operate when drawing circle or drawing arc with tape measure by improving drawing round locating device, has given new function with tape measure, has good practical values.
Description of drawings
Figure one looks synoptic diagram for the utility model master;
Figure two looks synoptic diagram for the utility model left side.
Wherein: 1 chi box, 2 chis are with lock to be decided device 3 buttons 4 springs 5 chi bands 6 and draws pins 7 latch segments 8 center of circle pilot pins 9 blind holes
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in Fig. 1 to 2, a kind of tape measure of using more, comprise: chi box 1, be around in chi band 5 in the chi box 1, be positioned at chi band 5 tape head hook bases picture pin 6, be located at the chi center of circle pilot pin 8 of deciding device 2, being located at chi box 1 bottom with lock on the chi box 1, it is characterized in that: described chi box 1 one sides are provided with blind hole 9; Be provided with spring 4 in the described blind hole 9; Described spring 4 upper ends are provided with button 3, and the lower end is provided with latch segment 7; Described center of circle pilot pin 8 is installed in the blind hole 9 by spring 4, latch segment 7.
The concrete course of work:
When drawing circle or drawing arc with the utility model, only need pull out chi band 5, promote button 3 downwards, thereby compression spring 4, the latch segment 7 that is positioned at spring 4 belows is being pushed down scale required on the chi band 7 downwards under the effect of spring force, center of circle pilot pin 8 ejects under the effect of spring force automatically simultaneously, because latch segment 7 is from vertically seeing center and 9 deads in line of center of circle pilot pin, so be the radius that center of circle pilot pin 8 is located by the scale of clamping block 7 lockings.After finishing using, only need upwards promote center of circle pilot pin 8(movable axis), center of circle pilot pin 8 will be hidden under the effect of spring force in the blind hole 9 on the chi box 1 automatically.
Only be when carrying out simple dimensional measurement when not needing picture circle or drawing arc, can the chi of being located on the chi box 1 is with lock to be decided device 2 and carry out the locking of chi band 7 by pressing, finish the surveying work of simple size.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineering technical personnel make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
Claims (3)
1. using tape measure one kind more, comprising: the chi box, be around in chi band in the chi box, be positioned at chi band tape head hook base the picture pin, be located at chi on the chi box and with lockly decide device, be located at the center of circle pilot pin bottom the chi box, it is characterized in that: described chi box one side is provided with blind hole; Be provided with spring in the described blind hole; Described spring upper end is provided with button, the lower end is provided with latch segment; Described center of circle pilot pin is installed in the blind hole by spring, latch segment.
2. as claimed in claim 1ly a kind ofly use tape measure, it is characterized in that: described latch segment is from vertically seeing center line and center of circle pilot pin dead in line more.
3. a kind ofly according to claim 1 use tape measure, it is characterized in that: described picture pin can protrude from the tape head hook base, also can recess be set on the base, allows the base be sharp tooth for one jiao more.
