Description

Novel bow compass
Technical field
The utility model relates to a kind of study article, especially a kind of novel bow compass.
Background technology
Compasses, a well-known drawing tool is also the study article of student's indispensability, no matter is pupil, or university student, or the people worked, and all may use compasses.
We use common compasses to draw bowlder; need first to determine that radius of a circle or two jiaos, mobile compasses are to specified size point-rendering; cumbersome like that; and the round size drawn is not very accurate; also often there will be pen core in drawing processes and the situation of skew occurs; cause needing again to draw circle, very large have impact on drawing efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel bow compass, its object is to solve common compasses and draw circle needs in advance with the inconvenience that ruler determination size is brought, and the problem that common compasses picture bowlder pen core easily offsets, improve accuracy and the stability of picture circle.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of novel bow compass, comprises thimble and pen core, it is characterized in that: described thimble upper end is provided with column; Described pen core upper end is provided with penholder; Described column is coaxial with described thimble, and described column is provided with cross through hole and is embedded in the transparent plastic sheet of cross through hole side; Described penholder is coaxial with described pen core, and described penholder is fixed with secondary chi; Described secondary chi front is provided with chute and sub scale line, and described chute is provided with main scale; Described main scale is through the described cross through hole on described column, and described main scale front is provided with main scale graduation mark; Described transparent plastic sheet is in side, described main scale front, and described transparent plastic sheet front center is provided with a vertical curve, and described vertical curve is in not only perpendicular to described main scale but also through in the plane at described column center.
The beneficial effects of the utility model are: can directly determine drawn radius of a circle by the graduation mark on main scale and secondary chi, and do not need to go to determine size with ruler again, use convenient, also improve the degree of accuracy of picture circle, simultaneously, by nib and thimble are be arranged in parallel, prevent pen core in the process of picture circle from offseting, improve the stability of compasses.
Further, described column is also provided with main scale standing screw, described main scale standing screw is connected with described column by screw thread, and is in side, the described main scale back side.
The beneficial effect of above-mentioned further scheme is: be fixed on column by main scale standing screw by main scale, and when preventing from drawing, main scale moves and affects the degree of accuracy of picture.
Further, described secondary chi upper end is provided with secondary chi standing screw, and described secondary chi standing screw is connected with described secondary chi by screw thread.
The beneficial effect of above-mentioned further scheme is: secondary chi and main scale are fixed by secondary chi standing screw, avoids main scale and secondary chi are mutually subjected to displacement and affect the accuracy of picture.
Further, described penholder is also provided with the pen core standing screw be threaded connection.
The beneficial effect of above-mentioned further scheme is: make to change pen core by pen core standing screw convenient, prevents loosening of pen core in drawing processes simultaneously.
Further, the zero graduation line of described main scale graduation mark is the low order end of described main scale; The zero graduation line of described sub scale line is the low order end of described secondary chi chute.
The beneficial effect of above-mentioned further scheme is: zero graduation line is arranged on the right, makes reading convenient.

In accompanying drawing, the list of parts representated by each label is as follows:
1, thimble, 2, pen core, 3, column, 4, penholder, 5, transparent plastic sheet, 6, secondary chi, 7, main scale, 8, main scale standing screw, 9, secondary chi standing screw, 10, pen core standing screw.
Detailed description of the invention
A novel bow compass as shown in Figure 1 and Figure 2, comprises thimble 1 and pen core 2, it is characterized in that: described thimble 1 upper end is provided with column 3; Described pen core 2 upper end is provided with penholder 4; Described column 3 is coaxial with described thimble 1, and described column 3 is provided with cross through hole and is embedded in the transparent plastic sheet 5 of cross through hole side; Described penholder 4 is coaxial with described pen core 2, and described penholder 4 is fixed with secondary chi 6; Described secondary chi 6 front is provided with chute and sub scale line, and described chute is provided with main scale 7; Described main scale 7 is through the described cross through hole on described column 3, and described main scale 7 front is provided with main scale graduation mark; Described transparent plastic sheet 5 is in side, described main scale 7 front, and described transparent plastic sheet 5 front center is provided with a vertical curve, and described vertical curve is in not only perpendicular to described main scale 7 but also through in the plane at described column 3 center.
Described column 3 is also provided with main scale standing screw 8, and described main scale standing screw 8 is connected with described column 3 by screw thread, and is in side, described main scale 7 back side.Described secondary chi 6 upper end is provided with secondary chi standing screw 9, and described secondary chi standing screw 9 is connected with described secondary chi 6 by screw thread.Described penholder 4 is also provided with the pen core standing screw 10 be threaded connection.The zero graduation line of described main scale graduation mark is the low order end of described main scale 7; The zero graduation line of described sub scale line is the low order end of described secondary chi 6 chute.
During use, first secondary chi standing screw 9 is turned, make main scale 7 and secondary chi 6 energy relative sliding, then the length of needs is slided into, namely main scale 7 zero graduation line adds the distance of secondary chi 6 zero graduation line to main scale 7 low order end to the distance of the vertical curve on transparent plastic sheet 5, and size tightens secondary chi standing screw 9 after determining, finally thimble 1 is inserted in centre point, pin column 3 on the other hand, pin penholder 4 on the other hand and start picture circle.If when the circle drawn is larger, loose main scale standing screw 8 can be adjusted in advance, to the right slip main scale 7, make the distance between pen core 2 and thimble 1 increase.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
