Abstract
The utility model discloses a kind of Multifunctional compasses, comprise compasses head (1), pin leg (2) and chi leg (5); Described pin leg (2) and chi leg (5) are linked together by trip bolt and compasses head (1).Described pin leg (2) is connected with removable chi bar (3), can realize measuring object length by chi bar (3); Described chi leg (5) indicates the angle value calculated by just profound theorem, realizes the measurement of angle.By above improvement, the utility model provides a kind of Multifunctional compasses, achieves picture circle, the integration of measuring length and taking measurement of an angle, easy to use and carry.
Description
Technical field
The utility model relates to a kind of drawing instrument, is specifically related to a kind of Multifunctional compasses.
Background technology
In real life, student or staff can bring many drawing instruments when drawing, and as ruler, protractor, the instrument such as compasses and pencil, it is very inconvenient to carry.Bowlder indispensable instrument drawn by compasses, but common calipers function is very single, and protractor is also can only measuring angle, and ruler also can only survey length.
In order to solve the problem, now provide Multifunctional compasses, by protractor, ruler and compasses three functions are integrated in one, and this Multifunctional compasses structure is simple, and easily manufacture, cost is low, is convenient for carrying.
Utility model content
The purpose of this utility model is to provide a kind of Multifunctional compasses at this, after improving, pin leg upper end is connected with compasses head, the aperture that lower end is provided with containing internal thread coordinates with the external screw thread of chi bar upper end, realize the function of the chi bar of the replaceable different accuracy of chi bar, the surface of chi bar indicates the scale measuring length, realizes the function of ruler.Described chi leg upper end is connected with compasses head, and lower end is connected with mechanical pencil, realizes drawing function, and surface indicates the angle calculated with SIN function, realizes the function of protractor.
The utility model is achieved in that a kind of Multifunctional compasses of structure, comprises compasses head, pin leg and chi leg; Described compasses head comprises handle, and shell and trip bolt, is characterized in that: handle, at its lower end is provided with external screw thread and is located at shell upper and coordinates containing the aperture of internal thread; Shell both sides have through hole, and through hole is provided with internal thread; Pin leg is connected with shell by trip bolt with chi leg.
According to Multifunctional compasses described in the utility model, it is characterized in that: described pin leg upper end is connected with compasses head, lower end be provided with containing internal thread aperture be located at chi bar upper external screw thread and match, described chi bar lower end is connected with needle point, indicates on chi bar surface the scale measuring length.
According to Multifunctional compasses described in the utility model, it is characterized in that: described chi leg upper end is connected with compasses head, and lower end is connected with mechanical pencil, indicate on chi leg surface the angle index calculated by just profound theorem.
Multifunctional compasses described in the utility model, comprises compasses head, pin leg and chi leg; Described compasses head comprises handle, shell and trip bolt, and handle, at its lower end is provided with external screw thread and coordinates with the aperture that shell upper end is offered containing internal thread; Shell two sides has through hole, and a through hole is provided with internal thread; By trip bolt, pin leg is connected with shell with chi leg.Described pin leg upper end is connected with compasses head, and the aperture that lower end is provided with containing internal thread coordinates with the external screw thread of chi bar upper end, realizes the function of the chi bar of the replaceable different accuracy of chi bar, and the surface of chi bar indicates the scale measuring length, realizes the function of ruler.Described chi leg upper end is connected with compasses head, and lower end is connected with mechanical pencil, realizes drawing function, and surface indicates the angle calculated with SIN function, realizes the function of protractor.
The utility model advantage is: Multifunctional compasses described in the utility model is connected with compasses head pin leg upper end after improving, the aperture that lower end is provided with containing internal thread coordinates with the external screw thread of chi bar upper end, realize the function of the chi bar of the replaceable different accuracy of chi bar, the surface of chi bar indicates the scale measuring length, realizes the function of ruler.Described chi leg upper end is connected with compasses head, and lower end is connected with mechanical pencil, realizes drawing function, and surface indicates the angle calculated with SIN function, realizes the function of protractor.Multifunctional compasses described in the utility model can realize ruler, being integrated in one of protractor and compasses three function, and structure is simple, easily manufacture and cost low.
Accompanying drawing explanation
Fig. 1 is the utility model overall schematic
As figure: 1a, handle; 1b, shell; 1c, trip bolt; 2, pin leg; 3, chi bar; 4, needle point; 5, chi leg; 6, mechanical pencil; 7, be threaded.
Detailed description of the invention
Be described in detail below in conjunction with accompanying drawing 1 pair of the utility model, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in the figure, the utility model provides a kind of Multifunctional compasses at this, comprises compasses head 1, chi leg 5 and pin leg 2.Described compasses head 1 comprises handle 1a, shell 1b and trip bolt 1c, handle 1a by lower end external screw thread be located at shell 1b upper end and be connected containing the aperture of internal thread, by trip bolt 1c pin leg 2, chi leg 5 is connected with compasses head 1, shell 1b two sides offers through hole, and a through hole offers internal thread.Described pin leg 3 upper end is connected with compasses head 1, and the aperture that lower end is provided with containing internal thread is connected with the external screw thread of chi bar 3 upper end, realizes the chi bar 3 changing different accuracy; Described chi bar 3 surface indicates the scale measuring length, and lower end is connected with needle point 4.Described chi leg 5 is connected with compasses head 1 with upper end, and lower end is connected with mechanical pencil, and chi leg 5 surface indicates the angle index calculated by SIN function.
Fixed by the needle point 4 below chi bar 3 in the process of drawing, draw circle with mechanical pencil 6; Can measure with chi bar 3 when measuring length, the value of requirement can be calculated by the value read on chi leg 5 by sine or the cosine law.
