Abstract

The utility model relates to a novel compasses which consist of support arms, concentric pins, a spring, a tripod, a rubber stand, a knob, a drawing arm, chalk and a cartridge. The utility model is characterized in that: the rubber stand is arranged on the angles of the tripod. The utility model is a novel compasses with high practical value.

Description

Novel bow compass
(1) field under:
The utility model relates to novel bow compass.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance, the big class of office appliance, write or drawing article, the assistant product group of writing or draw big group of circular curve plotter or analogous instrument, the little technical group field of compasses.Classification number is B43L9/02.
(2) background technology:
At present, the technology about compasses existing and that once had was all done very fruitful effort to the demand of novel bow compass, also once designed many outstanding technical schemes.As being declared by Zhao Zhengping of the Decree of Patent Office of China in 1996, Granted publication number is CN2224097Y, and China Patent No. (ZL) is: 95214560.X number utility model title is the utility model patent of " from rectilinear compasses ", the technical scheme that is adopted.At the compasses technical elements is a routine of great value invention, and it has solved the problem from rectilinear compasses effectively.But still have some deficits, it is inaccurate that it also is difficult to solve the old-fashioned compasses picture bowlder center of circle, and center of circle pin is the problem that iron nail is done does not have stability.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of novel bow compass.Inaccurate to solve the old-fashioned compasses picture bowlder center of circle, and center of circle pin is the problem that iron nail is done does not have stability.
The purpose of this utility model is achieved in that the novel bow compass of this utility model.Mainly by support arm, with one heart pin, spring, tripod, rubber angle, screw button, plotting hand, chalk, pen core and constitute.Its spring, chalk are by selecting for use on the market.Its support arm, plotting hand, pen core are cylindrical shapes, use plastic material, through the injection moulding processing and manufacturing.Its concentric pin is the aciculiform shape, uses stainless steel material, through forging processing and manufacturing.Its tripod is the A-frame shape, uses plastic material, through the injection moulding processing and manufacturing.Its rubber angle is an angular shape, uses elastomeric material, through synthetic processing and manufacturing.Its button that screws is the round steel shape, uses plastic material, through the injection moulding processing and manufacturing.Support arm adopts adhering method to be connected the top position of tripod, constitutes the conjuncted structure of cylindrical shape, and function is to play a supportive role.Pin adopts the insertion method to be connected the front position of pen core with one heart, constitutes the conjuncted structure of aciculiform shape, and function has been a point action.Spring adopts the insertion method to be connected the front position of pen core, constitutes spiral-shaped conjuncted structure, and function has been the elastic force effect.Spring adopts the insertion method to be connected the top position of tripod, constitutes the conjuncted structure of A-frame shape, and function is to play a supportive role.The rubber frame adopts adhering method to be installed in position on the angle of tripod, constitutes and protrudes the conjuncted structure of shape, and function is to play a supportive role.Screw button and adopt the insertion method to be installed in the outer position of support arm, constitute and protrude the conjuncted structure of shape, function has been a clamping action.Plotting hand adopts the bolt method of attachment to be installed in the top position of pen core, constitutes the conjuncted structure of branch shape shape, and function has been the drawing effect.Chalk adopts the insertion method to be installed in the front position of plotting hand, constitutes nib shape embedded structure, and function has been the drawing effect.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has been compared three advantages and improvement with original compasses technology;
The first, because the utility model has designed tripod in technical scheme, so support more stable;
The second, because the utility model has designed the rubber angle in technical scheme, so can reduce to slide;
The 3rd, because the utility model has designed the automatic pen-type pen core in technical scheme, so can be convenient; Thereby it is inaccurate just more effectively to have solved the old-fashioned compasses picture bowlder center of circle, and center of circle pin is the problem that iron nail is done does not have stability.
(4) description of drawings:
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the main TV structure schematic diagram of novel bow compass of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 support arm, 2 concentric pin 3 springs 4 tripods, 5 rubber angles 6 screw button 7 plotting hands 8 chalks 9 pen cores
(5) specific embodiment:
In the optimum implementation of novel bow compass of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: see also Fig. 1: as shown in the figure, novel bow compass of the present utility model.Mainly by support arm 1, with one heart pin 2, spring 3, tripod 4, rubber angle 5, screw button 6, plotting hand 7, chalk 8, pen core 9 and constitute.Support arm 1 adopts adhering method to be connected the top position of tripod 4, constitutes the conjuncted structure of cylindrical shape, and function is to play a supportive role.Pin 2 adopts the insertion method to be connected the front position of pen core 9 with one heart, constitutes the conjuncted structure of aciculiform shape, and function has been a point action.Spring 3 adopts the insertion method to be connected the front position of pen core 9, constitutes spiral-shaped conjuncted structure, and function has been the elastic force effect.Spring 3 adopts the insertion method to be connected the top position of tripod 4, constitutes the conjuncted structure of A-frame shape, and function is to play a supportive role.Rubber frame 5 adopts adhering methods to be installed in position on the angle of tripod 4, constitutes and protrudes the conjuncted structure of shape, and function is to play a supportive role.Screw button 6 and adopt the insertion method to be installed in the outer position of support arm 1, constitute and protrude the conjuncted structure of shape, function has been a clamping action.Plotting hand 7 adopts the bolt method of attachment to be installed in the top position of pen core 9, constitutes the conjuncted structure of branch shape shape, and function has been the drawing effect.Chalk 8 adopts the insertion method to be installed in the front position of plotting hand 7, constitutes nib shape embedded structure, and function has been the drawing effect.
Its dynamic structure: in force:
According to supporting mechanics principle, its pen core 9 acts on blackboard by concentric pin 2, thereby finishes the task of support.According to the compasses principle, its plotting hand 7 acts on blackboard by chalk 8, thereby finishes the task of drawing.So just realized the purpose of this utility model.Thereby it is inaccurate just to have solved the old-fashioned compasses picture bowlder center of circle, and center of circle pin is the problem that iron nail is done does not have stability.
Below by using method, the utility model is done more detailed description:
The novel bow compass of this utility model is work like this:
In use, when will draw, press pen core and screw button.According to supporting mechanics principle, its pen core 9 acts on blackboard by concentric pin 2, thereby finishes the task of support.According to the compasses principle, its plotting hand 7 acts on blackboard by chalk 8, thereby finishes the task of drawing.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery factory, take assembling to produce by batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
