Abstract
The utility model relates to an equal division device for oil painting teaching, which comprises an outer length rope, support bars and a central ring, wherein the support bars are the main support members in the equal division device, and the outer ends of the support bars are connected with the outer length rope; and the outer length rope is a common length of rope meeting the common requirements, the equal division length is marked in the form of 7 or 13 equal parts which are used as fixing points of the outer ends of the support bars, and assembly points of the support bars are all limited in one central ring, or through holes are manufactured at assembly ends of the support bars, and then the support bars are connected together by using a pin shaft, just like a folding fan of the prior art, thus forming a mode that angles between two adjacent support bars are equal. When an equal division needs to be carried out in the oil painting teaching process, the equal division device can be used for quick equal division marking to achieve the purposes of saving time and labor. The equal division device has the advantages of simple overall structure, convenient operation and use and better equal division effect, converts a complicated calculation process of equal division into a visualized ruler form, and facilitates the concrete operation of oil painting teaching.
Description
Technical field:
The utility model relates to the oil painting teaching and uses teaching aid, relates in particular to oil painting teaching usefulness and waits the branch device.
Background technology:
By prior art, when being divided into even number part, can adopt ruler, compasses or protractor to finish; When being divided into odd number part, need to adopt protractor or five equilibrium compasses, through computing or table look-up and finish.Use ruler or compasses, be divided into odd number part to an angle is very difficult thing, and also can only be approximate value when being divided into odd number part, can not be accurate, carry out five equilibrium at needs in the oil painting teaching process, especially have a lot of inconveniences under the situation of odd number part five equilibrium.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and device such as branch such as a kind of oil painting teaching usefulness grade is provided, and is simple in structure, easy for operation, can carry out five equilibrium to angle, circle or arc arbitrarily, makes things convenient for the field research needs of oil painting.
Oil painting teaching usefulness described in the utility model waits the branch device, includes outer length rope, support bar and center ring and forms.Said support bar is a body supports part of the present utility model, on the outer end of said support bar, is connected with outer length rope.Said outer length rope, according to length commonly used, get one section rope according to common needs length, go out the length of five equilibrium according to the formal notation of seven five equilibriums or ten trisections, as the point of fixity of the outer end of support bar, the assembly place of support bar all is controlled in the same center ring, or make through hole at the assembly end of support bar, as the folding fan of prior art, wear with bearing pin and to be associated in together, promptly form the form that the angle between each support bar equates.Need to wait timesharing in the oil painting teaching process, can use the utility model to carry out five equilibrium mark fast, time saving and energy saving.
Oil painting described in the utility model teaching usefulness waits the branch device, and one-piece construction is simple, and is easy for operation, the five equilibrium of complexity is calculated process can solve with ruler form intuitively, and effect is better.
Description of drawings:
Accompanying drawing 1 is the structural representation that oil painting teaching usefulness described in the utility model waits the branch device.1-outer length rope 2-support bar 3-center ring
Embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: oil painting teaching usefulness described in the utility model waits the branch device, includes outer length rope 1, support bar 2 and center ring 3 and forms.Said support bar 2 is body supports parts of the present utility model, on the outer end of said support bar 2, is connected with outer length rope 1.Said outer length rope 1, according to length commonly used, get one section rope according to common needs length, go out the length of five equilibrium according to the formal notation of seven five equilibriums or ten trisections, as the point of fixity of the outer end of support bar 2, the assembly place of support bar 2 all is controlled in the same center ring 3, or make through hole at the assembly end of support bar 2, as the folding fan of prior art, wear with bearing pin and to be associated in together, promptly form the form that the angle between each support bar 2 equates.Need to wait timesharing in the oil painting teaching process, can use the utility model to carry out five equilibrium mark fast, time saving and energy saving.Oil painting described in the utility model teaching usefulness waits the branch device, and one-piece construction is simple, and is easy for operation, and the five equilibrium calculation process of complexity can be solved with ruler form intuitively, and effect is better, the concrete operations that make things convenient for oil painting to impart knowledge to students.
