Abstract

The utility model discloses an intersecting line gauge. The middle part of a gauge rail is pivotally connected with a support pole and an index plate, and the two ends of the gauge rail are respectively articulated with a marking awl. The bottom of the support pole is provided with a thimble, and the middle part is provided with a sleeve structure, which can stretch vertically. The marking awl, penetrating in a casing pipe, is articulated in a slide way on the two ends of the gauge rail by a screw. An angle scale is fixed on a screw axis. The utility model adopts a mechanical structure to draw intersecting lines on objects of geometric shape. The utility model has the advantages that the drawing is direct, fast and accurate of low error, and the usage is easy so that ordinary technicians can command easily.

Description

Intersection is plan

Technical field:

The utility model relates to the setting-out instrument of geometric object intersection, is in particular to disclose a kind of intersection to plan, and belongs to the drawing instrument technical field.

Background technology:

Drawing intersection on geometric object generally is to adopt to make the technique of painting, utilizes craft or computer to draw according to geometrical principle, setting-out on object then, the difficulty of drawing a picture is bigger, non-general technology workman can grasp, and the error after the setting-out is bigger, has influenced the processing of workpiece.

Summary of the invention:

The utility model discloses a kind of intersection and plans, and has solved the difficult grasp that the present intersection technique of painting exists, the shortcoming that error is big.

Technical solution of the present utility model is as follows: be connected with pole and index dial at the middle part of the cross bar of planing, the plan two ends of cross bar are hinged with scriber respectively, wherein, the bottom of pole is a thimble, the middle part is the tube-in-tube structure that can stretch up and down, scriber is through in the sleeve pipe and is hinged in the slideway at the cross bar two ends of planing by screw, and angle scale is fixed on the screw shaft.

Good effect of the present utility model is: adopt frame for movement to draw intersection on the geometry object, directly quick and precisely, error is little, and is simple to operate, easy to use, and those of ordinary skill is grasped easily.

Description of drawings:

Fig. 1 is the utility model structure principle chart.

1～thimble, 2～adjusting rod, 3～pole, 4～endless screw support, 5～worm screw, 6～worm gear, 7～rotating disk, 8～pressing plate, 9～screw, 10～index dial, 11～scriber, 12～scriber sleeve pipe, 13～scriber slideway, 14～angle scale, the 15～cross bar of planing.

The specific embodiment:

With reference to Fig. 1, the plan middle part of cross bar 15 is provided with rotating disk 7, pole 3 is coupling index dial 10, pressing plate 8 at the center of rotating disk 7 by screw 9, being provided with worm gear 6 below the rotating disk 7 pays with the worm screw 5 formation worm gear engagements on the pole 3, can rotate around it, the middle part of pole 3 is telescopic adjusting rod 2, the bottom is a thimble 1, the plan two ends of cross bar 15 have scriber slideway 13, scriber 11 is through in the scriber sleeve pipe 12 can move up and down the adjustment distance, and be hinged in the slideway 13 by screw, angle scale 14 is fixed on the screw shaft; Described scriber 11 also can adopt the visible light beam side to carry out side apart from setting-out apart from instrument.

Claims
