Abstract

The utility model discloses a kind of novel angle gauges, including protractor body, the surface engraving of the protractor body has inverse time registration and up time registration, the lower end of the protractor body is provided with apex angle sight bead, angled rotary shaft is arranged in the top of the apex angle sight bead, the angle rotary shaft is fitted into angled indicating arm mobile jib, the surface of the angle indicating arm mobile jib offers reading window, the upper end of the reading window is provided with fastening screw, the fastening screw bolt has length adjustment bar, in a practical situation, when some angle measurements are the apex angles that can not directly contact, at this moment angle measurement can be measured indirectly with the protractor in the utility model, because it does not need to contact with the apex angle of angle measurement can measure angle indirectly, it is very easily in use, when can touch apex angle , can also directly go to measure, thus the scope of application of this protractor is more extensive.

Description

A kind of novel angle gauge
Technical field
The utility model belongs to protractor technical field, and in particular to a kind of novel angle gauge.
Background technique
Angle, measuring angle can be drawn, vertical line is drawn, parallel lines, surveys gradient, verticality, levelness, it can be when inside and outside straight Turn ruler in angle, moreover it is possible to the more accurate and visual degree for reading angle.
However existing protractor, when being used to the degree of angulation, it is necessary to apex angle is touched, if being not readily accessible to apex angle It then can not directly measure the degree at angle.
Utility model content
Technical problem to be solved in the utility model is in view of the above shortcomings of the prior art, to provide a kind of novel angulation Device, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of novel angle gauge, including protractor master Body, the surface engraving of the protractor body have inverse time registration and up time registration, and the lower end of the protractor body is provided with top Angled rotary shaft is arranged in the top of angle sight bead, the apex angle sight bead, and the angle rotary shaft is fitted into angled indicating arm Mobile jib, the surface of the angle indicating arm mobile jib offer reading window, and the upper end of the reading window is provided with fastening screw, described Fastening screw bolt has length adjustment bar, and the top of the length adjustment bar is provided with welt cross-staff.
Preferably, the bottom middle position of the protractor body is provided with apex angle sight bead.
Preferably, the protractor body and angle indicating arm mobile jib pass through angle rotation axis connection, the angle instruction The upper end of bar mobile jib offers reading window, and the reading window is internally provided with reading indicator.
Preferably, the top of the angle indicating arm mobile jib is provided with fastening screw, the angle indicating arm mobile jib and institute Length adjustment bar to be stated to link together by the fastening screw, the centre of the length adjustment bar is provided with fixed limiting slot, The top of the length adjustment bar is provided with welt cross-staff.
Preferably, the surface of the protractor body is provided with inverse time registration, and the upper end of the inverse time registration is provided with suitable When registration.
Compared with prior art, the utility model has the beneficial effects that in a practical situation, some angle measurements are can not be straight When the apex angle of contact, at this moment angle measurement can be measured indirectly with the protractor in the utility model, because it is simultaneously It does not need to contact with the apex angle of angle measurement and can measure angle indirectly, it is very easily, can in use When to touch apex angle, it can also directly go to measure, thus the scope of application of this protractor is more extensive.
Detailed description of the invention
Fig. 1 is the positive structure diagram of the utility model;
Fig. 2 is the length adjustment bar positive structure diagram of the utility model;
Fig. 3 is the fastening screw positive structure diagram of the utility model;
Fig. 4 is the reading window positive structure diagram of the utility model;
In figure: 1- protractor body, 2- apex angle sight bead, 3- inverse time registration, 4- up time registration, 5- angle rotary shaft, 6- Angle indicating arm mobile jib, 7- read window, 8- reads the fixed limiting slot of indicator, 9- fastening screw, 10- length adjustment bar, 11-, 12- welt cross-staff.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-Fig. 4 is please referred to, the utility model provides the following technical solutions: a kind of novel angle gauge, including protractor master Body 1, the surface engraving of protractor body 1 have inverse time registration 3 and up time registration 4, and the lower end of protractor body 1 is provided with apex angle and takes aim at Angled rotary shaft 5 is arranged in the top of foresight 2, apex angle sight bead 2, and angle rotary shaft 5 is fitted into angled indicating arm mobile jib 6, angle The surface of degree indicating arm mobile jib 6 offers reading window 7, and the upper end of reading window 7 is provided with fastening screw 9, and the bolt of fastening screw 9 has Length adjustment bar 10, the top of length adjustment bar 10 are provided with welt cross-staff 12.
In order to make protractor body 1 be more convenient for reading accuracy number, in the present embodiment, it is preferred that in the bottom of protractor body 1 Meta position, which installs, is equipped with apex angle sight bead 2.
It is more convenient and accurate in order to make to measure, in the present embodiment, it is preferred that protractor body 1 and angle indicating arm master Bar 6 is connected by angle rotary shaft 5, and the upper end of angle indicating arm mobile jib 6 offers reading window 7, and reading window 7 is internally provided with Read indicator 8.
It is flexible and fixed in order to make length adjustment bar 10 be more convenient for, in the present embodiment, it is preferred that angle indicating arm mobile jib 6 Top be provided with fastening screw 9, angle indicating arm mobile jib 6 and length adjustment bar 10 are linked together by fastening screw 9, long The centre of degree adjusting rod 10 is provided with fixed limiting slot 11, and the top of length adjustment bar 10 is provided with welt cross-staff 12.
