Description
Technical field
The utility model relates to a kind of novel bow compass of collision bead type telescopic legs, belongs to drawing tool field.
Background technology
Compasses are requisite instruments in hand-drawing process, and common compasses prop up leg length generally determines, and length is inadequate, the demand of the large figure of picture can not be met, and have the compasses folding process of some folding compass supporting legs also cumbersome, and generally can only have fixing length, the mapping demand of sizes can not be met.At present, also the compasses that a kind of Antenna Type is flexible are had, method for designing is the accordion structure being similar to radio antenna, such structural design realizes the flexible of compasses supporting leg easily, but this simple antenna stretch mode, that compares due to Antenna Type stretching structure loosens, and compasses supporting leg is easy to be pressed back by staff in the process of drawing.Therefore, the fold mechanism of Antenna Type, easily just producing offsetting by when small power, causing done figure to there is error, can not meet mapping demand very accurately.
Summary of the invention
The purpose of this utility model is the novel bow compass providing a kind of collision bead type telescopic legs, thus makes flexible compasses be provided with shoe, makes compasses supporting leg can not loosen due to the effect of pressure when drawing simultaneously.
A novel bow compass for collision bead type telescopic legs, mainly to comprise in supporting leg in compasses top nut, compass shelf, the outer supporting leg of left side compasses, left side compasses, bow compass positioning pin, hinge, the outer supporting leg of right side compasses, right side compasses nut, pencil-lead, collision bead, spring, tapping screw bottom supporting leg, compasses; It is characterized in that described compasses top nut has nicking, lower end is connected with compass shelf; Described compass shelf there is a hinge; Compasses outer supporting leg in described left side is hollow structure, and one end of the outer supporting leg of left side compasses is connected on the hinge of compass shelf, and one end to be enclosed within the compasses of left side on supporting leg; In the compasses of described left side, the bottom of supporting leg is provided with bow compass positioning pin, and supporting leg has a through hole in the compasses of left side; Compasses outer supporting leg in described right side is hollow structure, and one end of the outer supporting leg of left side compasses is connected on the hinge of compass shelf, and one end to be enclosed within the compasses of right side on supporting leg; In the compasses of described right side, the bottom of supporting leg is provided with pencil-lead by nut bottom compasses, and supporting leg has a through hole in the compasses of right side; Described collision bead, spring, tapping screw totally two covers, in the compasses being arranged on the left and right sides successively supporting leg through hole in, composition shoe.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is partial enlargement structural representation of the present utility model.
In figure: nut 9, pencil-lead 10, collision bead 11, spring 12, tapping screw 13 bottom supporting leg 8, compasses in supporting leg 4, bow compass positioning pin 5, hinge 6, the outer supporting leg 7 of right side compasses, right side compasses in the outer supporting leg 3 of compasses top nut 1, compass shelf 2, left side compasses, left side compasses.
Detailed description of the invention
Be below the better embodiment of the utility model patent, therefore do not limit protection domain of the present utility model.
As shown in Figure 1 and Figure 2, a novel bow compass for collision bead type telescopic legs, mainly to comprise in supporting leg 4 in compasses top nut 1, compass shelf 2, the outer supporting leg 3 of left side compasses, left side compasses, bow compass positioning pin 5, hinge 6, the outer supporting leg 7 of right side compasses, right side compasses nut 9, pencil-lead 10, collision bead 11, spring 12, tapping screw 13 bottom supporting leg 8, compasses; It is characterized in that described compasses top nut 1 has nicking, lower end is connected with compass shelf 2; Described compass shelf 2 there is a hinge 6; Compasses outer supporting leg 3 in described left side be hollow structure, and one end of the outer supporting leg 3 of left side compasses is connected on the hinge 6 of compass shelf 2, on the left of one end is enclosed within compasses on supporting leg 4; In the compasses of described left side, the bottom of supporting leg 4 is provided with bow compass positioning pin 5, and supporting leg 4 has a through hole in the compasses of left side; Compasses outer supporting leg 7 in described right side be hollow structure, and one end of the outer supporting leg 7 of left side compasses is connected on the hinge 6 of compass shelf 2, on the right side of one end is enclosed within compasses on supporting leg 8; In the compasses of described right side, the bottom of supporting leg 8 is provided with pencil-lead 10 by nut bottom compasses 9, and supporting leg 8 has a through hole in the compasses of right side; Described collision bead 11, spring 12, tapping screw 13 totally two covers, in the compasses being arranged on the left and right sides successively supporting leg through hole in, composition shoe.
The utility model novel structure, makes flexible compasses be provided with shoe, facilitates use.
