Description
Technical Field
The utility model belongs to the technical field of drawing appliance and specifically relates to a can conveniently extend an elongated ruler.
Background
The length of the ruler carried by students is limited, a longer ruler is sometimes needed in the drawing process, in addition, in the prior art, due to the displacement of the painting brush relative to the ruler, the brush ink leaves stains on the edge of the ruler, and the picture is further polluted.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses pass through the dovetail groove with two rulers and combine together, realize the ruler extension, the painting brush does not have the displacement for the ruler when drawing the straight line moreover, avoids a china ink to leave the spot at the ruler edge.
The utility model discloses the scheme that adopts is:
the ruler capable of being lengthened comprises a first ruler and a second ruler, wherein both the first ruler and the second ruler are provided with scale marks, the end of one side surface of the first ruler is provided with a convex plate, the convex plate is perpendicular to the first ruler, so that the plane of the first ruler is L-shaped, the side surface of the first ruler where the convex plate is located is provided with a dovetail groove, and one end of the dovetail groove is sealed by the convex plate; one side surface of the second ruler is provided with a dovetail joint, the first ruler and the second ruler are connected with the dovetail joint into a whole through the dovetail joint, the dovetail joint is in sliding fit with the dovetail joint, and the second ruler can slide along the length direction relative to the first ruler, so that the ruler is lengthened, and the ruler is convenient to carry and use; the cylinder diameter can also be measured.
The utility model has the advantages that:
the utility model can easily realize the extension of the ruler, and the painting brush has no displacement relative to the ruler when drawing a straight line, and only slides out the dovetail joint, thereby avoiding the pen ink from leaving stains on the edge of the ruler, and measuring the diameter of the cylindrical surface; first ruler and second ruler pass through the forked tail and are connected as an organic whole with the dovetail for it is all convenient to carry and use.
Drawings
The following is further illustrated in connection with the figures of the present invention:
fig. 1 is a schematic plan view of the present invention; FIG. 2 is a right side view of FIG. 1;
FIG. 3 is an enlarged partial schematic view of FIG. 2;
FIG. 4 is a schematic view in use; fig. 5 is a schematic view when measuring the cylinder diameter.
In the figure, 1 is a first ruler, and 2 is a second ruler.
Detailed Description
FIG. 1 is a schematic plan view of the present invention, reflecting the plane of the present invention,
fig. 2 is a right side view of fig. 1, reflecting the side of the present invention,
the ruler comprises a first ruler 1 and a second ruler 2, wherein both the rulers are provided with scale marks, the end of one side face of the first ruler 1 is provided with a convex plate, the convex plate is perpendicular to the first ruler 1, so that the plane of the first ruler 1 is L-shaped, the side face of the first ruler 1 where the convex plate is located is provided with a dovetail groove, and one end of the dovetail groove is sealed by the convex plate; one side of the second ruler 2 is a dovetail joint, the first ruler 1 and the second ruler 2 are connected with the dovetail joint through the dovetail joint as a whole, the dovetail joint is in sliding fit with the dovetail joint, and the second ruler 2 can slide along the length direction relative to the first ruler 1, so that the ruler is lengthened, and the ruler is convenient to carry and use.
Fig. 3 is a partially enlarged view of fig. 2, reflecting the tongue and groove sliding fit of the first and second rulers 1, 2.
As shown in fig. 4, when the drawing instrument is used, the second ruler 2 can slide relative to the first ruler 1, and the drawing pen can draw a straight line along with the translation of the second ruler 2, and the drawing pen does not need to be displaced relative to the second ruler 2, so that the ink does not leave stains on the edge of the second ruler 2, and the sliding of the second ruler 2 relative to the first ruler 1 is a parallel movement of the two edges.
As fig. 5 is a schematic view when measuring the cylinder diameter, the cylinder diameter can be measured.
The ruler capable of being lengthened comprises a first ruler 1 and a second ruler 2, wherein both the first ruler and the second ruler are provided with scale marks, a convex plate is arranged at one side end of the first ruler 1 and is perpendicular to the first ruler 1, so that the plane of the first ruler 1 is L-shaped, a dovetail groove is formed in the side surface of the first ruler 1 where the convex plate is located, and one end of the dovetail groove is sealed by the convex plate; one side of the second ruler 2 is a dovetail joint, the first ruler 1 and the second ruler 2 are connected with the dovetail joint through the dovetail joint as a whole, the dovetail joint is in sliding fit with the dovetail joint, the second ruler 2 can slide along the length direction relative to the first ruler 1, and therefore the ruler is lengthened, carrying and using are all convenient, and the diameter of a cylindrical surface can be measured.
