Abstract
The utility model discloses a horizontal float ball level switch which comprises a ball lever mechanism, a stilt lever mechanism, a swing level mechanism, a switch contact and a spring, wherein the ball lever mechanism is movably connected with a ball lever by a supporting base. A floating ball is fixedly connected to the right end of the ball lever, and magnetic steel is arranged at the left end of the ball lever. The stilt lever mechanism is arranged on the left side of the magnetic steel of the ball lever mechanism and is movably connected with the stilt lever by the supporting base. The right end of the stilt lever is provided with magnetic steel, and the left end of the stilt lever is provided with a dummy club which is arranged on the lower part of the right end of a swing lever. The swing lever mechanism is arranged on the left side of the stilt lever mechanism. The swing level mechanism is composed of the swing level and the supporting base. The right end of the swing level is provided with the dummy club which is supported under the switch contact. The spring is vertically connected to the upper side of the right-center of the swing level. The relative positions of two pieces of homopolar magnetic steel are controlled by the floating ball in the utility model according to liquid level, and the stilt lever is pushed by the mutual repulsive force of the magnetic steel to rotate to open or close the switch contact to output corresponding liquid level signals.
Description
Technical field
The utility model relates to a kind of appliance switch, and specifically, the utility model relates to a kind of appliance switch of monitoring liquid level.
Background technology
Liquid-level switch is a kind of appliance switch that liquid in container is monitored of being used for, the liquid-level switch of prior art is distinguished from structure and is mainly contained mechanical type and electronic type two big classes, its common structure characteristics are to be provided with switch contact at the liquid level setting position, variation control switch contact by liquid level is opened or is closed, in time, output device body fluid position signal objectively.But the weak point of prior art liquid-level switch is that switch contact stability when closure is subject to the liquid fluctuation influence and produces rub-out signal output inadequately, causes unnecessary loss.
The utility model content
The utility model provides a kind of by two homopolarity magnet steel phase repelling structures at the deficiencies in the prior art, and the horizontal floating ball liquid-level switch of opening or closing by the lever pushing switch contact.
A kind of horizontal floating ball liquid-level switch contains ball lever mechanism, lifts up linkage, swing-bar mechanism and switch contact and spring; Described ball lever mechanism flexibly connects ball lever by bearing, and ball float is fixedly connected on the right-hand member of ball lever, and magnet steel is located at the left end of ball lever; The described linkage of lifting up is located at ball lever mechanism magnet steel left side, is flexibly connected by bearing and lifts up bar, lifts up that the bar right-hand member is provided with magnet steel, left end is provided with boss and places fork right-hand member bottom; Described swing-bar mechanism is located at the left side of lifting up linkage, and swing-bar mechanism is made of fork and bearing, and the boss holder that the fork right-hand member is provided with is below switch contact, and spring is vertically connected on the upside that the stage casing of fork takes over.
In the said structure, ball float is according to the relative position of two homopolarity magnet steel of liquid level control, mutual expelling force by magnet steel promotes to lift up bar and rotates, and the elastic force that is aided with spring disconnects switch contact or the elastic force that overcomes spring makes the switch contact closure, exports corresponding liquid level signal.
The utility model horizontal floating ball liquid-level switch compared with prior art promotes to lift up bar by the mutual expelling force of two homopolarity magnet steel and rotates and the disconnection or the closure of control switch contact, its action accurately, reliable, and the not influence of liquid body fluctuation.
Description of drawings
The structure principle chart that Fig. 1 is the utility model horizontal floating ball liquid-level switch when the highest liquid level.
Fig. 2 is the structure principle chart of the utility model horizontal floating ball liquid-level switch when minimum liquid level.
Embodiment
Below with reference to the accompanying drawings shown in and embodiment, the utility model is further described.
The horizontal floating ball liquid-level switch contains ball lever mechanism, lifts up linkage, swing-bar mechanism and switch contact 3 and spring 2.Described ball lever mechanism flexibly connects ball levers 11 by bearing 10, and ball float 5 is fixedly connected on the right-hand member of ball lever 11, and magnet steel 9 is located at the left end of ball lever 11.The described linkage of lifting up is arranged on ball lever mechanism left side, is flexibly connected by bearing 8 and lifts up bar 7, lifts up bar 7 right-hand members and is provided with magnet steel 4, and the left end of lifting up bar 7 is provided with boss and places fork 1 right-hand member bottom.Described swing-bar mechanism is made of fork 1 and bearing 6, and the boss holder that the right-hand member of fork 1 is provided with is below switch contact 3, and spring 8 is vertically connected on the upside that the stage casing of fork 1 takes over.In the said structure, ball float 5 directly reflects the liquid level of liquid, and magnet steel 9 that ball float 5 connects by ball lever 11 left ends and the mutual expelling force of lifting up the magnet steel 4 that bar 7 right-hand members are connected promote to lift up bar and rotate and impel switch contact disconnection or closure.When liquid level is raised to desired location, the relative area maximum of two homopolarity magnet steel, its mutual expelling force is also maximum, and under the boosting of spring 2, switch contact 3 disconnects, and sends liquid level signal.Otherwise, when liquid level drops to desired location, ball float 5 is made up time with liquid and is rotated, the magnet steel 9 that ball lever 11 left ends connect clockwise rotates simultaneously to magnet steel 4, by the mutual expelling force of two magnet steel,, prize swing-bar mechanism through lifting up the effect of linkage, overcome the elastic force of spring 2, make the corresponding liquid level signal of switch contact 3 closed outputs.
Claims (2)
