Abstract

The utility model discloses an angle-marking gauge for pipes, which belongs to a tool for measuring the angles of pipes. The angle-marking gauge for pipes solves the problem that lines can be marked on the pipes after sample plates are made existing in prime art. The angle-marking gauge for pipes is composed of a positioning marking plate, a marking pen, a pen holder, a positioning magnetic plate, a connecting shaft, an angle-displaying disk, etc. Marks with needed angles are directly marked on the pipes, and therefore, pipes with needed angles can be cut according to the marks. The angle-marking gauge for pipes is suitable for marking on the pipes used in all industries and determining angles. The angle-marking gauge for pipes has the advantages of high precision, convenient operation, labor saving, material saving, and high work efficiency.

Description

Tubing angle line drawing ruler

Tubing angle line drawing ruler of the present utility model belongs to the angle apparatus of measuring tubing.

Now, people at first will measure, calculate when making the tubing of various angles, the model that draws is attached to the line that draws on the tubing to model, so then, different tubing, different angles just must be produced different models, waste time and energy, and have reduced production efficiency.

The purpose of this utility model is to propose a kind of model that need not, the tubing angle line drawing ruler that directly setting-out takes measurement of an angle on tubing.

The utility model is made up of location scribing plate, detail pen and a holder, connecting axle, angle display panel, location magnetic sheet etc., be enclosed within on the tubing by locating scribing plate, the location magnetic sheet goes to required angle place, two are arranged in movably draw respectively hemicycle or ellipse of paintbrush of the spill chute of location on the scribing plate on pipe outer surface, thereby connect a circle or elliptical line, line can go out the tubing of required angle by metal gas cutting or jack saw according to this.

Accompanying drawing 1 is a structure diagram of the present utility model.

Do a detailed description below in conjunction with 1 pair of the utility model of accompanying drawing.

Location scribing plate (4) is curved, and a spill chute (5) is all arranged on two about it, and is recessed Be furnished with detail pen pen tray (2) on the shape chute (5), pen tray (2) can be come along spill chute (5) Travelling backwards is moving, is inserted with detail pen (3) in detail pen pen tray (2), the pen of two detail pens (3) Head is relatively inside, and detail pen (3) can move forward and backward in pen tray (2); At location scribing plate (4 ) front end be the screw (1) of stationary positioned scribing plate on tubing, when the location scribing plate (4) cover In the time of on tubing, tighten fixed screw (1), location scribing plate (4) namely is fixed on the tubing; The rear end of location scribing plate (4) is the axle (7) that scribing plate is connected with location magnetic sheet (8), connects Spindle (7) can make on the one hand location scribing plate (4) about two expand outwardly as the center of circle take axle, To be enclosed within on the tube outer diameter, make on the other hand the location magnetic sheet (8) take axle as the center of circle at 90 ° with interior Rotate in the scope, the assembling of the both sides of connecting axle (7) be carved with 0 °～90 ° the angle display panel ( 6), it is concordant with the top edge of locating magnetic sheet (8) that 0 ° of display panel (6) is located, during angulation, and magnetic Plate (8) top edge scale is the tubing angle that magnetic sheet angle of inclination that is aequum are drawn; The location Magnetic sheet (8) is made by Magnetic gauge stand, is for being adsorbed on the tubing to increase line drawing ruler at tubing Steadiness, make slightly lower folding shape, purpose is to inhale fully mutually with tubing, the end of magnetic sheet (8) End is Magnetic Control switch (9), has or not orientation magnetic in order to the magnetic force of control location magnetic sheet (8) Plate can be made by light materials such as aluminium alloy, highstrenghtpistons.

Now doing one with regard to specific embodiment of the utility model describes in detail.

The tubing of a 45 if desired, at first will locate magnetic sheet (8) is that the center of circle is rotated and made its top edge to locating to 45 ° of angle display panel (6) with connecting axle (7), tubing is inserted in the location scribing plate (4) of line drawing ruler, and tilt to 45 ° with the location magnetic sheet (8) parallel, opening magnetic force gauge tap (9) to continuous magnetic potential puts, location magnetic sheet (8) is promptly inhaled mutually with tubing, the fixed screw (1) that is right after scribing plate (4) front end screws, make about scribing plate (4) two tightly to be stuck on the pipe, adjust the position of two detail pens (3) then, make nib can fully touch pipe outer surface, move two detail pen pens holder (2), drive detail pen (3) when making it in spill chute (5), to move and on tube-surface, stay two semicircles or half elliptic picture trace, and make two semicircles or half elliptic draw a continuous circle or the ellipse of being connected into of trace, magnetic force gauge tap (9) is threaded to the demagnetization position, make location magnetic sheet (8) nonmagnetic, break away from tubing, unscrew fixed screw (1), open the location scribing plate (4) about two, take off tubing, so just draw on the tubing line of a 45, line can go out the tubing of 45 by metal gas cutting or briar according to this.

Because of tubing is cylinder, so its acute angle tubing that intercepts out can be considered as corresponding with it obtuse angle simultaneously, can be general as the tubing at the tubing at 35 ° of angles and 145 ° of angles.

Tubing angle line drawing ruler of the present utility model is suitable on the tubing that every profession and trade is used setting-out and makes angle, measures accurately, saves human and material resources, increases work efficiency, and has higher promotional value.

Claims

1. tubing angle line drawing ruler, it is characterized in that by location scribing plate (4), detail pen (3), detail pen pen holder (2), connecting axle (7), angle display panel (6), location magnetic sheet compositions such as (8), the location scribing plate about two curved, one spill chute (5) is all arranged on it, detail pen pen holder (2) can drive the detail pen (3) that is interspersed in therebetween and move in chute (5), the front end of location scribing plate (4) is fixed screw (5), the rear end is connecting axle (7), connecting axle (7) had both connected about location scribing plate (4) two, and can to make it with axle (7) be outwards to open a business in the center of circle, connect scribing plate (4) and location magnetic sheet (8) again, and to make location magnetic sheet (8) be the center of circle with the connecting axle rotates in interior scope at 90 °, be carved with 0 °～90 ° angle display panel (6) in the assembling of the both sides of connecting axle (7), location magnetic sheet (8) is made by Magnetic gauge stand, and its end has a magnetic force gauge tap (9).
