Abstract

The utility model discloses a pipe intersecting line marking gauge, the structure of which is a positioning pointer in a V-shaped groove of an axle seat. The shaft and the outside chute sleeve form a leg, the rotating arm arranged in the chute sleeve and the pointer which is arranged on the rotating arm and can slide up and down in the chute parallel to the axis form another leg, the rotating arm is positioned by the shaft seat, the rotating arm rotates around the shaft, and the sliding needle rotates along with the rotating arm and slides up and down in the chute to mark a intersecting line on the circular tube. The drawing gauge is suitable for drawing intersecting lines of circular pipes with the diameters of 50 mm-2000 mm. Simple structure, easy manufacture, detachable parts, convenient carrying and use, in particular to a pipeline installation work site.

Description

Round pipe interseation line scriber

The utility model belongs to the line instrument field, is specifically related to a kind of pipe intersecting lines and plans.

Solve the circle that is projected as that runs in the pipe fitting at present, actual is the line problem of intersection, mainly is to take to make model by projection, marks the traditional-handwork method of intersection then with model parcel pipe surface.Chinese patent 86204124 discloses a kind of multi-functional lining instrument, its objective is that solution can mark the arbitrarily angled intersection when crossing of any geometrical body and pipe directly and accurately on the body surface, mark various curves such as arbitrarily angled circle, ellipse, circumference Along ent position on plane, interior positive camber, male and female face.Its major technique feature is to be provided with 360 ° of dial discs and angle vernier on magnetic bases, on dial disc, be equipped with can 180 ° radially movable montants, the montant arm pull cover that can move up and down is housed on the montant, arm pull and scriber are housed on the montant arm pull, on montant, also be equipped with along the montant axis and can slide up and down and rotary montant disk, 90 ° of dials and cross bar are arranged on the montant disk, and cross bar is provided with cross bar arm pull cover and scriber.The deficiency of this invention is because function is more, thus complex structure, and manufacture process requirement is higher.

The purpose of this utility model provides a kind of simple in structure, and is easily manufactured, and the pipe intersecting lines that uses that is easy to carry is plan.

The technical scheme that realizes this purpose is to be equipped with in the axle bed V-type groove and axle coaxial line and retractable positioning pointer, the axle outside of fixedlying connected with axle bed is equipped with and is pivoted and can be adjusted to chute sleeve pipe with a coaxial line, the cursor that also can have scale with axis normal in groove stably is housed in the chute on chute sleeve pipe top, one end of cursor is provided with the chute parallel with axis, but the scriber that easy on and off moves is housed in the chute.Shaft extension goes out the part of chute sleeve pipe as handle.Axle, axle bed and positioning pointer dead in line form the one leg of planing, and cursor and scriber are combined into the one leg in addition of planing.

This advantage of planing is small and exquisite, and is simple in structure, easy to carry, solved with simple way and be projected as round intersection line problem on pipe, time saving and energy saving, improved operating efficiency, and the precision height.

The utility model has following accompanying drawing:

Fig. 1 pipe intersecting lines duty front view of planing;

Fig. 2 chute sleeve structure profile;

Fig. 3 pipe intersecting lines duty vertical view of planing.

Embodiment:

V-type fluted shaft seat 1 top is fixed with screw thread with axle 2 lower ends, be equipped with in the V-type groove with the axle coaxial line and according to the pipe surface condition can be by the threaded adjusting height positioning pointer 3, its effect is the tram when determining to plan work.On the axle chute sleeve pipe 4 is housed, the chute sleeve pipe adopts steel ball 11 and holding screw 12 to roll to be connected or gap fiting mode realizes and being connected of axle that its effect is an adjusting chute sleeve pipe, make its when making circular motion can with axle and positioning pointer maintenance axiality.The chute sleeve pipe is provided with the fixedly holding screw 7 of cursor 6 of the chute 5 that becomes 90 ° with axis and two pieces, the cursor 6 of the ruler shape of band millimeter scale is housed in the groove, behind the radius according to the definite intersection that will mark of the scale on the cursor, tighten two pieces of holding screws, the rotary chute sleeve pipe can drive cursor and realize circular motion.One end of cursor be provided with parallel with axis and with axis at the conplane chute 8 and the fixing holding screw 9 of scriber 10, but the scriber 10 that easy on and off slides is housed in the chute, make circular motion with cursor, scriber fluctuates with the pipe surface appearance, is projected as round intersection thereby mark on the pipe surface.

This is plan applicable to diameter is the line work of the pipe intersecting lines of 50mm～500mm, if change axle bed, cursor and scriber, is the line work of the pipe intersecting lines of 500mm～2000mm applicable to diameter.

This plans simple in structure, is convenient to make, and various parts can be dismantled, adorn box, be easy to carry, and easy to install, especially pipe fitting is on-the-spot uses this to plan, and can solve the intersection problem rapidly, accurately, easily.

Claims
