Abstract
The utility model discloses an extendable ruler which is provided in order to solve the problem that the ruler of the prior art cannot extend and cannot meet the length requirement of actual use. The utility model provides the design of the extendable ruler. The extendable ruler comprises a ruler body, measurement carving marks are arranged on the ruler body, at least two through holes are arranged at one longitudinal end of the ruler, and projecting spots having the same size and number with the through holes are arranged at the opposite end. After the projecting spots are embedded and fixed in the through holes, a longer ruler is formed to meet the requirements of actual use.
Description
Technical field
The utility model relates to a kind of lattice chi, particularly a kind of extensible lattice chi.
Background technology
People are in study, and drawing is in the process of drawing; The length of lattice chi usually can not satisfy the needs of actual use when drawing longer orthoscopic; Usually can take segmentation to draw, but in the process of segmentation, can cause drawn straight line not straight, badly influence work quality and operating efficiency.
The utility model content
To the problems referred to above, the utility model provides a kind of lattice chi that can prolong.
For achieving the above object, the utility model lattice chi comprises lattice chi body, and it is provided with the tolerance indentation, and a said lattice chi end longitudinally is provided with at least two through holes, and a rightabout end is provided with and said hole size, the raised points that quantity is suitable.
Particularly, the raised points of described lattice chi can inlay, be fixed to other one in the through hole of same lattice chi.
Particularly, the two ends of described lattice chi are provided with unfilled corner, match after said two unfilled corners combination.The beneficial effect of the utility model:
The utility model can prolong the lattice chi through raised points and through hole that the two ends at the lattice chi are provided with respectively, can make two or two above lattice chis be connected into a longer lattice chi, has eliminated the problem that the lattice chi falls short of in real life.
Description of drawings
Fig. 1 is the structural representation of the utility model one specific embodiment;
Fig. 2 is that the A of the said specific embodiment of the utility model is to structural representation;
The specific embodiment
Below in conjunction with Figure of description the utility model is done further description.
As illustrated in fig. 1 and 2, the utility model can prolong the lattice chi, comprises lattice chi body 1; It is provided with tolerance indentation 2; A said lattice chi end longitudinally is provided with at least two through holes 3, and a rightabout end is provided with and said hole size, the raised points 4 that quantity is suitable.Inlay, be fixed to other one through the raised points 4 that can prolong the lattice chi and can prolong same model in the through hole 3 of lattice chi, make two lattice chis form one, can realize many in theory the combination of lattice chi longer lattice chi with one.
Particularly, the two ends of the utility model lattice chi are provided with unfilled corner, match after two unfilled corners 5 and 6 combinations, inlay with other lattice chi, fixing in, can make it fixing more firm, and be more conducive to actual use needs.
More than; Be merely the preferred embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claim was defined.
Claims (3)
1. a lattice chi comprises lattice chi body, and it is provided with the tolerance indentation, it is characterized in that: a said lattice chi end longitudinally is provided with at least two through holes, and a rightabout end is provided with and said hole size, the raised points that quantity is suitable.
2. lattice chi according to claim 1 is characterized in that: the raised points of described lattice chi can inlay, be fixed to other one in the through hole of same lattice chi.
