Abstract
The utility model discloses a drawing board for mechanical drawing, which belongs to the technical field of mechanical drawing and comprises a board body used for holding drawing paper. A guide groove is arranged on the periphery of the board body, a guide seat is movably arranged in the guide groove, a basic rule is rotationally arranged on the guide seat, and an angle measurer and a rotary rule are rotationally arranged at ends of the basic rule. The drawing board for mechanical drawing is simple in structure, reasonable in design, convenient for students to be drawn, convenient in carrying and storing and capable of increasing drawing speed and reducing teaching burden of teachers.
Description
Technical field
The utility model relates to a kind of mechanical drawing apparatus, relates in particular to a kind of mechanical drawing and uses drawing board.
Background technology
At present, training and the study of in the teaching process of mechanical major, carrying out mechanical drawing are indispensable courses for the student of engineering and polytechnic universities.Though along with popularizing of computer application, cad technique is able to promote, hand-drawing still has very important meaning in the engineering field; And the teaching of mechanical drawing seems very important, in the teaching process of mechanical drawing, needs the student to be equipped with drawing appliance; Like multiple drawing appliances such as drawing board, T-square, set square, compasses and angel measuring instruments, these apparatus generally disperse to place, so carry inconvenience; Use loaded down with trivial details, also inconvenience keeping, and when being used through them; The student is difficult to hold, and has reduced drawing speed.
Summary of the invention
It is a kind of simple in structure, reasonable in design that the purpose of the utility model is to provide, and makes things convenient for the student to draw, and is easy to carry and takes care of, and can effectively improve the mechanical drawing of drawing speed and use drawing board.
In order to reach above purpose; The technical scheme that the utility model adopted is: drawing board is used in mechanical drawing; Comprise the plate body that is used to place drawing paper, it is characterized in that: be provided with gathering sill around the said plate body, be movably equipped with guide holder in the said gathering sill; Rotate on the said guide holder and be provided with basic chi, the end of said basic chi is rotated respectively and is provided with angel measuring instrument and rotary ruler.
The utility model is also implemented through following measure: said guide holder is provided with the holding screw that is used for fixing basic chi.
Said angel measuring instrument and rotary ruler are rotationally connected through bearing pin and said basic chi.
The beneficial effect of the utility model is: simple in structure, reasonable in design, and make things convenient for the student to draw, be easy to carry and take care of, can effectively improve drawing speed, alleviated teacher's teaching load.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Shown in accompanying drawing; Drawing board is used in mechanical drawing; Comprise the plate body 1 that is used to place drawing paper, be provided with gathering sill 2 around the said plate body 1, be movably equipped with guide holder 3 in the said gathering sill 2; Rotate on the said guide holder 3 and be provided with basic chi 4, the end of said basic chi 4 is rotated respectively and is provided with angel measuring instrument 5 and rotary ruler 6.Can drive basic chi 4 through mobile guide seat 3 and in gathering sill 2, move, thereby make things convenient for the student to draw; Owing to be equipped with gathering sill 2 around the plate body 1, so only pass through basic chi 4 and end rotational angle measuring instrument 5 and rotary ruler 6, cooperatively interact with them and can accomplish basic drawing work, easy to use.
Said guide holder 3 is provided with the holding screw 7 that is used for fixing basic chi 4.When regulating after guide holder 3 is positioned at the position of gathering sill 2, can fix it through holding screw 7, thereby make things convenient for the student to draw.
Said angel measuring instrument 5 is rotationally connected through bearing pin 8 and said basic chi 4 with rotary ruler 6.Being rotatably connected respectively through bearing pin 8 can make rotary ruler 6 measure required angle according to angel measuring instrument 5 to rule, easy to use, has alleviated teacher's teaching load.
During use; Guide holder 3 is slided in gathering sill 2; After sliding into the desired position, make basic chi 4 and guide holder 3 vertical and fix, match with rotary ruler 6 according to angel measuring instrument 5 then and find the position of line accurately, pin rotary ruler 6 on the other hand and fix through holding screw 7; Rule on the other hand, easy to use.Can make as required during use and go up the gathering sill 2 that is provided with around the guide holder 3 winding board bodies 1 and move, can comprehensive satisfied drawing requirement, and to collect various apparatus be one, use, carry simple and convenient, also alleviated teacher's teaching load simultaneously.
The utility model is simple in structure, and is reasonable in design, makes things convenient for the student to draw, and is easy to carry and takes care of, and can effectively improve drawing speed, alleviated teacher's teaching load.
