Abstract
The utility model discloses a valve limit switch which comprises a base and a shell, wherein the base is internally provided with a driving shaft and a contact device, the lower end of the driving shaft penetrates through the base, the driving shaft is provided with two eccentric wheels in a sleeved mode, and the eccentric wheels correspond to the contact device. The valve limit switch has the advantages that the structure is simpler, and the control is more convenient.
Description
Technical field
The utility model relates to a kind of remote control switch, is specifically related to a kind of valve limit switch.
Background technology
Valve limit switch is a kind of mechanical switch conventional on market, general switching device can not directly limit the displacement of specific features, and valve limit switch can be controlled by measuring the mode of its choosing dress angle the formation of these parts, be widely used in the fields such as handling equipment, lift, stage dress are standby, valve, more particularly to the adventurous place of staff, as bridge crane is called a taxi or the occasions such as deceleration, buffering such as suspender.This valve limit switch drives the sensitive switch in contact making device by the rotation of cam, utilizes weak electric signal to transmit to control, and reaches location or the termination of equipment.
But the cam of the cam set of existing valve limit switch mostly is a plurality of projections, complex structure, and control trouble.
Utility model content
In order to overcome the deficiency of background technology, it is a kind of simple in structure that the utility model provides, and controls more simple valve limit switch.
The technical scheme that the utility model adopts: a kind of valve limit switch, comprise pedestal, housing, be provided with driving shaft, contact making device in described pedestal, described driving shaft lower end passes pedestal, on described driving shaft, cover has two eccentric wheels, and described eccentric wheel is corresponding with contact making device.
Described contact making device comprises contact making device housing, and described contact making device housing is provided with button, shell fragment, and described shell fragment one end is fixedly connected with contact making device housing, and the other end extends to outside button.
Described housing top is provided with indicating device, and described indicating device matches with driving shaft upper end.
Described indicating device comprises instruction unit, connecting portion, and described connecting portion is along the long shape hole on same circle, passes long shape hole be connected with housing by bolt.
Described base bottom is provided with adjustable support.
The beneficial effects of the utility model are: adopt above scheme, described driving shaft can be with unrestricted rotation of movable eccentric wheel 360 degree, and structure is simpler, controls convenient.
