Abstract
The utility model relates to a measuring tape type compass which is used in middle and primary school teaching. Technically, the utility model adopts such parts as a steel measuring tape, a protractor and a sucking disk as major parts. One end of the steel measuring tape is provided with a pen inserted circular ring. One side of the housing of the measuring tape is provided with the protractor, and the other side is provided with the sucking disc. The protractor and the sucking disc are fixed on a rotating shaft with screws. Meanwhile, the sucking disc is fixed on a support frame of the sucking disc with screws, and the support frame of the sucking frame is fixed on the housing of the measuring tape with support frame fixing screws. The housing of the measuring tape is provided with a measuring tape locking device. The utility model solves the problem of sliding in drawing of an existing two-leg type compass, can draw a circle and an arc and measure length accurately, and can be widely applied in the middle and primary school teaching.
Description
Technical field:
The utility model relates to the reel tape type compasses of a kind of middle and primary schools teaching usefulness.
Background technology:
At present, the compasses of teaching usefulness generally all adopt wooden bipod compasses, because mostly school's blackboard is cement face or glass face, and the point of compasses is an iron, during use, easily skids, and therefore, the circle that draws is very lack of standardization, and result of use is poor, carries also inconvenient.
The utility model content:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and a kind of reel tape type compasses that provide, these compasses can draw accurately circle and arc, measure length, and easy to carry, not only be applicable to teaching, also applicable to designing and mapping.
The technical scheme that its technical problem that solves the utility model adopts is: in a side of placing the steel tape box vertically is that a side of steel tape shell is provided with sucker and is fixed on the sucker stand with screw, and sucker stand is to be fixed on the bend tape casing with the support fixed screw; Side in addition at bend tape casing is a steel tape box base front end, be provided with protractor, be fixed on its base front end with screw, and be that the automatic bayonet socket that the flexible rule box opening part is provided with the iron sheet making is the tape measure locking device on bend tape casing, and be provided with at tape measure one end and insert an annulus, at first the sucker on these compasses is inhaled during use and on blackboard or draughting board, done the center of circle and open tape measure penholder is gone into to insert in the annulus by setting the radius size rotation can draw accurately and justify or circular arc by setting radius of a circle, but use amount hornwork angulation also.
The beneficial effects of the utility model are, and are simple in structure, are easy to carry, easy to use, can draw circle, circular arc, the branch cyclotomy of any radius, measuring angle.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure,
1, inserts an annulus, 2, protractor, 3, the tape measure locking device, 4, bend tape casing, 5, sucker stand, 6, the support fixed screw, 7, sucker.
The specific embodiment:
In the accompanying drawings, be provided with one at steel tape one end and insert an annulus 1, side at bend tape casing 4 is provided with protractor 2, side is provided with sucker 7 in addition, the two is fixed on the rotating shaft with screw, simultaneously sucker 7 usefulness screws are fixed on the sucker stand 5, with support fixed screw 6 sucker stand 5 are fixed on the bend tape casing 4, being provided with the automatic bayonet socket of making of iron sheet on bend tape casing 4 is tape measure locking device 3.
