Description
Technical field
The present invention relates to technical field of electronic components, relate in particular to a kind of cover rod potentiometer.
Background technology
Potentiometer is a kind of conventional electronic devices and components; be widely used on the by-pass cock of various electric equipments; traditional potentiometer is all to regulate current potential by the rotation of adjusting rod at present; but because the rotation of adjusting rod always and between containment vessel sidewall produces certain friction; often with the passing of time be easy to loosening leakage into dust, cause potentiometer unstable properties.
Summary of the invention
For problems of the prior art, the invention provides a kind of cover rod potentiometer, effectively prevent the friction in rotary regulating lever and between containment vessel sidewall.
Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of cover rod potentiometer, it is characterized in that: comprise containment vessel, current potential adjustable ring, insulating base, adjusting rod, brush, described current potential adjustable ring is arranged on insulating base by being arranged on the rotating shaft of insulating base center, described current potential adjustable ring comprises resistive element and adjustable ring, one end of described brush is pressed on resistive element, the other end is fixed on insulating base, described adjusting rod penetrates containment vessel inside from the side of containment vessel, described adjusting rod is made up of loop bar and interior bar, loop bar is enclosed within the outside of interior bar, loop bar outside is connected and fixed with containment vessel sidewall, one end top of described interior bar outside containment vessel is provided with regulating nut, top, one end in containment vessel inside is provided with regulating wheel, regulating wheel is pressed on adjustable ring.
Preferably, described current potential regulates and also comprises fixed bar, the center of fixed bar is connected with rotating shaft, fixed bar can rotate around rotating shaft, resistive element and adjustable ring are separately fixed at the both sides of fixed bar, resistive element and adjustable ring are semicircle annular, the ring heart of semicircular ring and the axis coinciding of rotating shaft.
Preferably, described adjustable ring lower surface is provided with nickel dam, is provided with magnet in regulating wheel.
Preferably, the two ends of described adjustable ring are equipped with limited block.
Preferably, described regulating wheel is equipped with corresponding band with the contact-making surface of adjustable ring.
Preferably, between described loop bar and interior bar, be provided with lubricating oil.
The beneficial effect that the present invention reaches is: the double design that the present invention is arranged to loop bar and interior bar by adjusting rod makes not worry in rotary regulating lever that adjusting rod and containment vessel sidewall are because often friction causes crack to enter grey phenomenon; and make the combination of regulating wheel and adjustable ring tightr by nickel dam being set at the lower surface of adjustable ring and magnet being set in regulating wheel, regulate more stable.
Brief description of the drawings
Fig. 1 is a kind of structural representation that overlaps rod potentiometer of the present invention;
Fig. 2 is a kind of lateral section structural representation that overlaps rod potentiometer of the present invention.
Detailed description of the invention
In order to further describe technical characterstic of the present invention and effect, below in conjunction with the drawings and specific embodiments, the present invention is described further.
See figures.1.and.2, a kind of cover rod potentiometer, comprise containment vessel 1, current potential adjustable ring, insulating base 2, adjusting rod 8, brush 6, described current potential adjustable ring is arranged on insulating base 2 by being arranged on the rotating shaft 4 of insulating base center, described current potential adjustable ring comprises resistive element 5 and adjustable ring 3, one end of described brush 6 is pressed on resistive element 5, the other end is fixed on insulating base 2, described adjusting rod 8 penetrates containment vessel 1 inside from the side of containment vessel 1, described adjusting rod 7 is made up of loop bar 83 and interior bar 84, loop bar 83 is enclosed within the outside of interior bar 84, loop bar 83 outsides and containment vessel 1 sidewall are connected and fixed, one end top of described interior bar 84 outside containment vessel 1 is provided with regulating nut 81, top, one end in containment vessel 1 inside is provided with regulating wheel 82, regulate wheel load 82 on adjustable ring 3, described current potential regulates and also comprises fixed bar 9, the center of fixed bar 9 is connected with rotating shaft 4, fixed bar 9 can rotate around rotating shaft 4, resistive element 5 and adjustable ring 3 are separately fixed at the both sides of fixed bar 9, resistive element 5 and adjustable ring 3 are semicircle annular, the ring heart of semicircular ring and the axis coinciding of rotating shaft 4.
Because loop bar 83 is not connected with regulating nut 81 and regulating wheel 82, can't make loop bar 83 and then rotate so rotate regulating nut 81, when use, drive interior bar 84 to rotate and then drive the rotation of regulating wheel 82 by rotating regulating nut 81, finally make adjustable ring 3 rotate in the work of regulating wheel 82, thereby make resistive element 5 be moved and change current potential for the position of brush 6 mutually, for the rotation of interior bar 84 is more flexible, between loop bar 83 and interior bar 84, be wiped with lubricating oil. In order to make the rotation that regulating wheel 82 can more stable effective drive adjustable ring 3, be equipped with corresponding band at regulating wheel with the contact-making surface of adjustable ring, and the lower surface at adjustable ring 3 is also provided with nickel dam, in regulating wheel 82, be provided with magnet, thereby the pressure that can effectively increase like this between regulating wheel 82 and adjustable ring 3 strengthens frictional force. In order to prevent that bar 84 in inordinate rotation from making to cause the disengaging of brush 6 and resistive element 5, is equipped with limited block 7 at the two ends of adjustable ring 3.
Above-described embodiment does not limit the present invention in any form, and all technical schemes of taking the form that is equal to replacement or equivalent transformation to obtain, within all dropping on protection scope of the present invention.
