Abstract

The utility model relates to a multifunctional extended ruler-compass, which comprises a ruler unit, a slider and a bolt with angular graduations. The utility model is provided with multiple functions of a lengthening ruler, a compass with adjustable radius in a large range, a protractor, a set square and a tee square. The utility model has the advantages of simple structure, reliable connection, convenient operation, carrying and storage, high possibility of implementation.

Description

Multi-functional lengthening ruler

Technical field

The utility model relates to the metering device field, particularly a kind of multi-functional lengthening ruler.

Background technology

At present, generally the ruler of Shi Yonging, compasses are measured or the size of graphing, be limited in scope, and and the protractor that often uses, set square, T-square separately, function singleness, this uses and carries to preserve and bring very big inconvenience to actual.Though many outstanding designs also once appearred at this problem, for example multi-functional Telescopic ruler, folding ruler since complex structure be connected the not firm further lengthening that has limited this type of ruler.

Summary of the invention

Technical problem to be solved in the utility model: overcome the deficiency in the existing ruler technical scheme, propose a kind of simple in structure, connect firm multi-functional lengthening ruler and solve the problems referred to above.

The technical solution adopted in the utility model: (1) constitutes the basic composition unit by the bolt of ruler unit, slide block and band angle index; (2) finish the lengthening function of ruler by the connecting ring on the ruler body, adapter sleeve and connecting bolt; (3) realize the compasses function by ruler, slide block, radius index line and Length Indication line; (4) realize the function of protractor by the bolt of ruler, angle index line, band angle index; (5) by the bolt realization set square of ruler, shifting chute, band angle index and the function of T-square.

The beneficial effects of the utility model: solved the lengthening problem of ruler, it is simple in structure that ruler has been had, and use, preservation and easy to carry integrate the advantage of the function of ruler, compasses, set square, protractor and T-square.And the utility model exploitativeness is strong, and market prospects are preferably arranged.

Specific embodiments

Known by Fig. 1: the ruler unit is made up of ruler body [1], angle index line [2], shifting chute [3], adapter sleeve [4], connecting ring [5], length graduation mark [6].When after the adapter sleeve [4] of one-level ruler unit put between the connecting ring [5] of previous stage ruler unit, insert connecting bolt [16] again and promptly finish connection between the ruler unit.Produce in batches for convenient, the length scale marker of rulers at different levels unit is got and is made unanimity, and the ruler of lengthening gets measurement result to the end with addition.

Known by Fig. 2, Fig. 4: slide block can be enclosed within on the ruler and slide, and in order to adjusting the size of compasses radius, slide block bolt [10] and fastening bolt [8] are fixed in order to the location of realizing radius respectively and drawing pen [17], center of circle pilot pin [15].Length (by reading on the ruler) on two slide blocks between the radius index line [11] is radius that compasses are got.

Known by Fig. 3, Fig. 5: the bolt [12] by a ruler and a band angle index is formed protractor, and the difference of angle index line [14] indicating value of two angle index index lines [2] indication is the size of the folded angle of ruler.

Known by Fig. 6, Fig. 7: the bolt [12] of band angle index can slide along shifting chute [3], and the position adjustment of being done appropriateness by the bolt [12] of ruler and band angle index can obtain needed set square and T-square.

Claims

1. multi-functional lengthening ruler of forming by the bolt [12] of ruler body [1], slide block body [7], band angle index, it is characterized in that: ruler body [1] indicates Length Indication line [6] up and down, and about be connected with adapter sleeve [4] and connecting ring [5] respectively, wherein adapter sleeve [4] and the available connecting bolt of connecting ring [5] [16] are connected in series, and the central authorities of ruler body [1] have shifting chute [3].

2. multi-functional lengthening ruler according to claim 1, it is characterized in that: slide block body [7] can be enclosed within ruler body [1] and go up slip, slide block body [7] one ends are equipped with slide block bolt [10], and the other end is connected with adapter sleeve [9], wherein on the adapter sleeve [9] fastening bolt [8] are housed.

3. multi-functional lengthening ruler according to claim 1 is characterized in that: bolt can slide in the shifting chute [3] of ruler body [1], angle index line [14] is arranged on the bolt, and be furnished with nut [13].
