Изобретение относитс к электротехнике и может найти применение в конвейе{)а.The invention relates to electrical engineering and can be used in the pipeline {) a.
Известны концевые выключатели, содержащие корпус с закрепленным на нем бесконтактным узлом, рычаг с роликом и флажком , установленный на пальце и имеющий возможность воздействи на бесконтактный узелШ.Limit switches are known, comprising a housing with a contactless unit fixed on it, a lever with a roller and a flag mounted on a finger and having the ability to act on a contactless node.
Однако эти концевые выключатели неудобны в эксплуатации.However, these limit switches are inconvenient to operate.
Цель изобретени - улучшение условий эксплуатации.The purpose of the invention is to improve the operating conditions.
С этой целью концевой выключатель, содержащий корпус с закрепленным на нем бесконтактным узлом, рычаг с роликом и флажком, установленный на пальце и имеющий возможность воздействи на бесконтактный узел, снабжен кронштейном с упором и противовесом, корпус выполнен также с упором, при этом палец установлен в кронштейне с возможностью поворота и жестко соединен с корпусом, а противовес становлен на рычаге. Упоры расположены диаметрально противоположно относительно пальца .For this purpose, a limit switch comprising a housing with a contactless unit fixed on it, a lever with a roller and a flag mounted on a finger and having the ability to act on a contactless node is provided with a bracket with an emphasis and a counterweight, the housing is also designed with an emphasis; bracket can be rotated and rigidly connected to the housing, and the counterweight is placed on the lever. The stops are located diametrically opposite to the finger.
На фиг. 1 изображен концевой выключатель в трех положени х; на фиг. 2 - раз2FIG. 1 shows the limit switch in three positions; in fig. 2 - time2
рез А-А на фиг. 1; на фиг. 3 - разоез Б-Б на фиг. 2.cut A-A in FIG. one; in fig. 3 - disconnecting BB in FIG. 2
Концевой вьн лючатель состоит из рычага 1 в сборе с роликом 2. фла.жком 3 и противовесом 4, установленного на пильце ,5с возможностью поворота относительно бесконтактного узла 6, закрепленного на корпусе 7.The limit switch consists of a lever 1 assembled with a roller 2. fla. 3 and a counterweight 4 mounted on a pilas, 5c can be rotated relative to a contactless node 6 mounted on the housing 7.
Палец 5 соединен с корпусом 7 жестко и в свою очередь установлен в кронштейне 8 с возможностью поворота относительно 10 оси 9.The finger 5 is connected to the housing 7 rigidly and in turn is installed in the bracket 8 with the possibility of rotation about 10 axis 9.
На корпусе 7 закреплен упор 10. ограничивающий поворот рычага 1 против часовой стрелки на пальце 5. На кронштейне 8 закреплен упор 11, преп тствующий повороту корпуса 7 по часовой стрелке относительно оси 9.On the housing 7, the stop 10 is fixed. The limiting turn of the lever 1 counterclockwise on the finger 5. On the bracket 8, the stop 11 is fixed, which prevents the turn of the housing 7 clockwise relative to the axis 9.
Момент от силы т жести противовеса меньше мо.мента от силы т жести корпуса с закрепленным на нем бесконтактным УЗЛОМ 20 относительно оси пальца.The moment from the force of the weight of the counterweight is less than the torque from the force of the body of the body with the contactless HINGE 20 fixed on it with respect to the axis of the finger.
Концевой выключатель работает следующим образом.The limit switch works as follows.
