T-square

Abstract: The utility model discloses a multifunctional drawing table. According to the main structure, the drawing table comprises a drawing tabletop, a box frame, four table legs, a front panel, a rear panel and a bottom board. The defects that an existing drawing table can not be folded, is large in occupied space, can not be moved and is single in function are overcome. Foldable structures are adopted for key parts such as the drawing tabletop, the table legs and a T square, in this way, the overall structure is compact, and moving and carrying are convenient. According to the multifunctional drawing table, the dual-purpose effect is achieved, and the multifunctional drawing table can be used as a drawing table and a travel suitcase. The multiple functions of lighting, folding and moving and tabletop inclination angle and height adjusting are integrated, and the multifunctional drawing table can be well adaptive to different heights, postures and ground environments, can well meet the requirements of multi-disciplinary multi-specialty drafting/drawing teaching and the professional design requirement and is good in market prospect.

Abstract: The utility model relates to a drawing board tool for class. The drawing board tool for class is small in size and suitable for being used in class, drawing paper can be placed to appropriate positions quickly and accurately and fixed on a drawing board rapidly, and drawing frames can be drawn quickly. The drawing board tool is characterized in that a national standard A3 drawing paper border line and a national standard A4 drawing paper border line are arranged on the front of the drawing board, the front of the drawing board is provided with positioning pressing blocks embedded with pressing block magnets, eight drawing board magnets are also embedded in the positions, corresponding to the pressing block magnets, of the back of the drawing board, national standard A3 pressing block border lines and national standard A4 pressing block border lines are arranged at the positions of four corners of the national standard A3 drawing paper border line and the national standard A4 drawing paper border line respectively, the four positioning pressing blocks respectively align to the four sets of national standard A3 pressing block border lines or the four sets of national standard A4 pressing block border lines to be placed on the front of the drawing board, drawing board size scales are arranged on the periphery of the drawing board, zero graduation of the drawing board size scales on the upper and left sides is arranged in the middle, zero graduation arranged on the surface of a square board is disposed in the middle, the drawing board only satisfy placement of A3 drawing paper and A4 drawing paper according to requirements of drawing classes, the square board of a T square is connected with a sliding board into a whole, and the sliding board is perpendicular to the surface where size scales of the T square are located. The drawing board tool is suitable for being used in drawing classes in colleges as well as in drawing classes in middle schools.

Abstract: The basic and the most fundamental instruments for technical drawing are mechanical pencil, eraser, ruler, triangle, and remarkably the t square. However, the students may encounter several problems with regards to these basic drawing instruments. The student may find it bulky bringing all these instruments everyday in school; the student may find it inconvenient using several instruments one at a time and the student may not be able to buy all these drawing instruments. This research introduces an instrument that would help students in technical drawing. The researchers dubbed the device as Flexi Drawing Instrument (FDI). Aside from the conventional drawing instruments, there are already existing devices that are relatively parallel to the present research. There exist an Adjustable Angle T Square (www.alibaba.com) that is rotatable and has dual functions of drawing lines and angles. On the contrary, this drawing instrument can only provide 30, 45, 60, and 75 degree angle. In addition, this dual functions instrument can only be used one at a time. Meaning to say, one can only draw an angle unless the t square is not used. This type of instrument cannot satisfy the needs of our drafting and drawing students for it is very limited in its function and has a limited degree- angle available. Multi-Mark Layout Tool (www.rockler.com) is another drawing instrument that is multi-functional. This instrument can take multitude of measuring, marking and layout tasks. Furthermore, it can
