Abstract
The utility model discloses a kind of instrument for drawing stair drawing, comprise at least two the first bars be parallel to each other, the length of the first bar increases from top to bottom successively, and be provided with two the second bars between the first adjacent bar, the second bar is mutually vertical with the first bar; The end of the first bar that the length in the first bar that one end of the second bar is adjacent with two is less is connected; The first bar that length in the first bar that one end of second bar is adjacent with two is larger is flexibly connected; First bar slidably connects the 3rd bar.When using the utility model device to draw stair figure, step is simple, and easily maintenance drawing is clean, drawing efficiency is high; When ratio is less, utilize the movement of the first bar, the second bar and the 3rd bar, can be easy to even partition Along ent, ensure equidistant translation ruler, error is little, easy to operate.
Description
Technical field
The utility model belongs to architectural drawing technical field of tools, is specifically related to a kind of instrument for drawing stair drawing.
Background technology
At present, the common method of drawing stair is combined with T-square and set square.The method of point parallel lines spacing such as stair plane divides stair step number, then draws step surface.The technique of painting of stair profile: according to the slice location marked in stair ground floor plan and projecting direction, words wall body axis, flooring, platform and bench position, then the position drawing wall body thickness, land thickness, crossbeam, finally divide stair step, divide equally along horizontal bench direction number of marking time, draw vertical curve of marking time, more vertically divide equally and play step number, draw horizontal line, obtain bench tread and riser outline line, draw and mark time and after riser profile of tooth figure line, then wipe unnecessary boost line.
Utilize these instruments to draw to have the following disadvantages: during drafting stair figure, step is many, and need frequent mobile T-square and set square, auxiliary line is many, and drawing not easily keeps clean, and efficiency is very low; When ratio is less, not easily even partition Along ent, can not ensure equidistant translation ruler, error is large.Draw secondary ten step stair to cut open figure and will carry out determining the actions such as Along ent, mobile T-square, set square, erasing boost line more than 60 time, operation is inconvenience very.
Utility model content
The purpose of this utility model is to provide a kind of instrument for drawing stair drawing, solves the problem that the drafting drawing efficiency existed in prior art is low, drawing not easily keeps totally, error is large.
The technical scheme that the utility model adopts is, for drawing an instrument for stair drawing, comprise at least two the first bars be parallel to each other, the length of the first bar increases from top to bottom successively, be provided with two the second bars between the first adjacent bar, the second bar is mutually vertical with the first bar; The end of the first bar that the length in the first bar that one end of the second bar is adjacent with two is less is connected; The first bar that length in the first bar that one end of second bar is adjacent with two is larger is flexibly connected; First bar slidably connects the 3rd bar.
Feature of the present utility model is also,
One end of second bar is provided with the first chute, and the first bar that the length in two adjacent the first bars is less is slidably connected by chute and the second bar.
Each first bar is provided with the second chute, and the 3rd bar is provided with slide block, and the 3rd bar is slidably connected with each first bar respectively by the second chute and slide block.
3rd bar is at least provided with 2, is parallel to each other and length is equal between the 3rd bar.
Spacing between the first adjacent bar is equal.
First bar, the second bar and the 3rd bar are provided with scale mark.
The beneficial effects of the utility model are: when using the utility model device to draw stair figure, step is simple, and easily maintenance drawing is clean, drawing efficiency is high; When ratio is less, utilize the movement of the first bar, the second bar and the 3rd bar, can be easy to even partition Along ent, ensure equidistant translation ruler, error is little, easy to operate.
Accompanying drawing explanation
Fig. 1 is that the utility model is for drawing the structural representation of the instrument of stair drawing;
Fig. 2 is that the utility model is for drawing the working state figure of the instrument of stair drawing;
Fig. 3 is the utility model for the connection diagram of the first bar and the second bar drawing the instrument of stair drawing.
In figure, 1. the first bar, 2. the second bar, 3. the 3rd bar, 4. the first chute, 5. the second chute, 6. slide block, 7. scale mark.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of instrument for drawing stair drawing, as shown in Figure 1, the length comprising the first bar 1, first bar 1 that at least two are parallel to each other increases from top to bottom successively, two the second bar 2, second bars 2 are provided with mutually vertical with the first bar 1 between the first adjacent bar 1; The end of the first bar 1 that the length in the first bar 1 that one end of the second bar 2 is adjacent with two is less is connected; The first bar 1 that length in the first bar 1 that the other end of the second bar 2 is adjacent with two is larger is flexibly connected; First bar 1 slidably connects the 3rd bar 3, the end of such first bar 1 is stepped, is convenient to draw stair.
As shown in Figure 3, the first bar 1 that one end of the second bar 2 is provided with length in the first adjacent bar 1 of the first chute 4, two less is slidably connected by chute 4 and the second bar 2.Each first bar 1 all on be provided with the second chute the 5, three bar 3 and be provided with slide block 6, the 3rd bar 3 is slidably connected with each first bar 1 respectively by the second chute 5 and slide block 6.3rd bar 3 is at least provided with 2, is parallel to each other and length is equal between the 3rd bar 3.Spacing between the first adjacent bar 1 is equal.3rd bar 3 is provided with scale mark 7.
In use, can draw stair along the first bar 1 and the second bar 2, as shown in Figure 3, this device utilizes the left and right of the 3rd bar 3 to move in parallel character, control one group of parallel first bar 1 equidistant telescopic, realize even regulation stair section and to mark time size and play the object of step size.
The utility model has the advantage of: when drawing stair figure, step is simple, and easily maintenance drawing is clean, drawing efficiency is high; When ratio is less, utilize the movement of the first bar 1, second bar 2 and the 3rd bar 3, can be easy to even partition Along ent, ensure equidistant translation ruler, error is little, easy to operate.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, many variations can also be made to it.
