Abstract

The utility model discloses a magnetic switch air cylinder, which comprises a cylinder body and a piston, wherein the piston is arranged in the cylinder body, a magnetic ring is arranged on the piston, and a reed switch is arranged at the outer side of the cylinder body. The magnetic switch air cylinder has the characteristics that the structure is simple, the magnetic ring is arranged on the piston, in addition, the magnetic switch is used for detecting the air cylinder stroke position, and the air cylinder is controlled to do reciprocating movement.

Description

Magnetic switch cylinder
Technical field
The utility model relates to cylinder design field, is specifically related to a kind of magnetic switch cylinder.
Background technique
Existing air cylinder detecting piston position needs to install in addition stroke valve, position limit switch, or block is set on piston rod.
Model utility content
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of magnetic switch cylinder is provided.
The technological scheme that the utility model adopted is for achieving the above object: magnetic switch cylinder, comprise cylinder body, piston, described piston is arranged in cylinder body, on described piston, magnet ring is installed, on described piston, magnet ring is installed, reed switch is equipped with in described cylinder body outside.
Described reed switch comprises tongue, and connected protective circuit, action indicator, and described tongue, protective circuit, action indicator are installed in switch housing.
Feature of the present utility model is: simple in structure, by magnet ring is installed on piston, and detect cylinder stroke position, control cylinder to-and-fro motion with magnetic switch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, action indicator 2, protective circuit 3, switch housing 4, piston 5, magnet ring 6, cylinder barrel 7, tongue.
Embodiment
As shown in Figure 1; the utility model comprises cylinder barrel 6, piston 4; described piston 4 is arranged in cylinder barrel 6; described piston 4 is arranged in cylinder barrel 6; on described piston 4, magnet ring 5 is installed; reed switch is equipped with in described cylinder barrel 6 outsides, and described reed switch comprises tongue 7, and connected protective circuit 2, action indicator 1.Described tongue 7, protective circuit 2, action indicator 1 are installed in switch housing 3; move near tongue 7 when the piston 4 of magnet ring 5 is housed, the magnetic line of force makes its magnetization by tongue 7, and two tongues 7 are attracted contact; switch connection; when magnet ring 5 returns while leaving, field weakening, two tongues 7 flick; switch disconnects; due to being switched on or switched off of switch, making solenoid valve commutation, thereby realize the to-and-fro motion of cylinder.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and inventive concept thereof, within all should being encompassed in protection domain of the present utility model.
