Description

Предлагаемый нивелир относитс  к нивелирам с визирными приспособлени ми, снабженными диоптрами.The proposed level relates to levels with sighting devices equipped with diopters.

На чертеже фиг. 1 изображает вид нивелира сбоку; фиг. 2 - вид его спереди; фиг. 3 - разрез по линии АБ на фиг. 1; фиг. 4 - вид визирной трубы со щелью.In FIG. 1 shows a side view of the level; FIG. 2 - front view; FIG. 3 shows a section along the line AB in FIG. one; FIG. 4 - view of the sighting tube with a slit.

Нивелир состоит из обыкновенной коробки 7 с отверстием дл  вставки визирной трубы 2, С правой стороны коробки / на оси 8 установлен жесткий отвес 3, на концах которого в перпендикул рном к нему направлении вделаны цилиндрические трубки 4 дл  закреплени  в них тонких стальных игол 5. Кордбка слева имеет стойку-пластинку 6 дл  укреплени  визирного волоска 7, соответственно которому в визирной трубе 2 на конце, обращенном к глазу, имеетс  визирна  Щель.The level consists of an ordinary box 7 with an opening for inserting the sighting tube 2. A hard plumb 3 is installed on the right side of the box / on axis 8, at the ends of which cylindrical tubes 4 are installed perpendicular to it to fix thin steel needles 5. Cordbka on the left has a stand plate 6 for strengthening the sighting hair 7, according to which in the sight tube 2 there is a sighting sight on the end facing the eye.

Волосок 7 и центр щели визирной трубы наход тс  в одной плоскости. Иглы 5 вставлены в отвес 3 под пр мым углом к направлению центра т жести отвеса, вследствие чего при горизонтальном положении прибора волосок 7 и иглы 5 совмещаютс . На этом последнем свойстве и основан, принцип устройства предлагаемого нивелира.The hair 7 and the center of the slit of the sighting tube are in the same plane. The needles 5 are inserted into the plumb line 3 at a right angle to the direction of the center of gravity of the plumb line, as a result of which, when the device is horizontal, the hair 7 and the needles 5 are aligned. The principle of the proposed leveling device is based on this last property.

Предмет изобретени .The subject matter of the invention.

Нивелир, отличающийс  применением жесткого отвеса 3 с иголками 5, служащими дл  совмещени  их в одной плоскости с горизонтальным волоском 7 в цел х установки инструмента в горизонтальное положение.A level, characterized by the use of a hard plumb 3 with needles 5, serving to align them in the same plane with horizontal hair 7 in order to set the tool in a horizontal position.
