Abstract
The utility model belongs to the technical field of study articles, and provides a drawing pen-rolling aid. The drawing pen-rolling aid comprises a body and a cylindrical roller which is arranged on the body, wherein the body is provided with a hole for accommodating a pen. The utility model has the advantages that: the drawing pen-rolling aid has a simple structure, is convenient to use, and is only provided with a roller and a hole for accommodating the pen; the drawing pen-rolling aid is only required to be sleeved on a pen point, so that the pen point is prevented from slipping under the action of sliding of the cylindrical roller; and meanwhile, an aid with a measuring distance can be selected, the rolling circles of the roller are calculated through a distance measuring chip, and the length of a drawn straight line is displayed on a display screen, so that straight lines of any length can be drawn conveniently and optionally in a very practical way.
Description
Technical field
The utility model belongs to the study article technical field, relates to a kind of drawing and rolls an assistor.
Background technology
Have now when manual drawing engineering drawing, form and need describe straight line, usually people adopt ruler and pencil to be used simultaneously just and can to finish the work, but because the limited length of ruler, because when the straight line that drafting length is grown, can not accomplish without any letup, influenced operating efficiency like this, become the direction that present technique field personnel make great efforts because design a kind of instrument that can draw straight line arbitrarily.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, and provides a kind of simple in structure, and is easy to use, can make things convenient for the drawing of any length straight line that draws arbitrarily to roll an assistor.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: an assistor is rolled in a kind of drawing, it is characterized in that: comprise body and be arranged on cylindrical roller on the body, offer the hole that is used to place a space on the described body.
The measure of taking for the optimization such scheme specifically comprises:
Roll in the assistor in above-mentioned a kind of drawing, described body comprises fixed part and moving part, and described hole is positioned on the fixed part, and roller is fixed on the moving part, and moving part bends downwards with respect to fixed part.
Roll in the assistor in above-mentioned a kind of drawing, have anti-slop serrations on the outer circumference surface of described roller.
Roll in the assistor in above-mentioned a kind of drawing, also be built-in with the range finding chip that is used to calculate the roller rolling number of turns in the described body, on body, also be provided with the display screen that is used to show drawn straight length.
Compared with prior art, advantage of the present utility model is simple in structure, easy to use, a roller and the hole of putting pen are only arranged, only need it is enclosed within on the nib, rely on the slip of cylinder roller to prevent that nib from skidding, simultaneously also can select to have the assistor of range finding, it calculates the roller rolling number of turns by range finding chip, and shows drawn straight length on display screen, can make things convenient for any length straight line that draws arbitrarily very practical.
Description of drawings
Fig. 1 is that an assistor overall structure schematic diagram is rolled in this drawing;
Fig. 2 is the structural representation after this drawing is rolled an assistor and pen is cooperated.
Among the figure, body 1; Fixed part 11; Moving part 12; Roller 3; Anti-slop serrations 31; Hole 4; Display screen 5.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As depicted in figs. 1 and 2, an assistor is rolled in this drawing, comprises body 1 and is arranged on cylindrical roller 3 on the body 1, and offer the hole 4 that is used to place a space on the described body 1, hole 4 is nested with on pen during use.
Here body 1 comprises fixed part 11 and moving part 12, and hole 4 is positioned on the fixed part 11, and roller 3 is fixed on the moving part 12, and moving part 12 bends downwards with respect to fixed part 11, like this when with this assistor with cooperate rear roller 3 just in time with plane contact; In order to prevent that nib skids when drawing straight line, has anti-slop serrations 31 on the outer circumference surface of described roller 3.
This drawing is rolled an assistor and also can be adopted the assistor that has range finding in addition, mainly be also to be built-in with the range finding chip that is used to calculate the roller 3 rolling number of turns in the body 1, on body 1, also be provided with the display screen 5 that is used to show drawn straight length, so conveniently on display screen 5, show drawn straight length.
