Technical field

This utility model is related to instrument field, and in particular, it is related to a kind of liquidometer with limit switch function Device.

Background technology

Liquidometer is a kind of device made according to law of connected vessels, can clearly indicate out the height of liquid level.

At present, in prior art, Authorization Notice No. discloses one kind for the Chinese utility model patent of CN201408050Y Magnetic turning column liquid level meter, its body are made up of a metal circular tube, upper and lower ends flange seal, are vertically connected with method on body Orchid, for body and the connection for holding liquid container, built with magnetic float, which is a hollow seal cylindrical metal to body Long ball, built with the permanent magnet of one piece of horizontal positioned, with strong magnetic attraction, which is swum on this internal liquid level, with liquid level liter Drop fluctuates, and during its strong magnetic attraction drives instruction device, front is white, and reverse side is redness, is combined as a whole with little axle, can The magnetic turned column rotated around little axle is made 180 ° of turned columns and is rotated, and when liquid level rises, magnetic turned column is overturn as redness, magnetic when liquid level declines Property turned column upset be white, and the particular location scale of liquid surface lifting is indicated by the scale for being placed in magnetic turned column both sides.

The magnetic turning column liquid level meter prevents liquid level from continuing to rise when liquid level reaches the upper limit with automatically cutting off power supply High problem.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of with limit switch function Liquid level meter apparatus, can automatically cut off power supply to prevent liquid level from continuing to raise when liquid level is increased to the upper limit.

For achieving the above object, this utility model provides following technical scheme：A kind of liquid with limit switch function Position counter device, including Raw material pail and the liquidometer being connected with Raw material pail, are provided with the liquidometer and are controlled into Raw material pail The turned column indication panel that is magnetic is installed in the on and off switch of charging, the liquidometer, vertical direction sliding in the Raw material pail sets Be equipped with magnetic floating block, be provided with the Raw material pail be right against on and off switch first opening, be provided with the Raw material pail with The impeller of the first open horizontal direction sliding connection, is fixedly installed driving member on the magnetic floating block, the driving member with The transmission that the motion transmission of driving member vertical direction can be moved towards the first opening direction for impeller is provided between impeller Component.

By adopting above-mentioned technical proposal, when the liquid level in Raw material pail is constantly raised, the magnetic floating block on liquid level also can Rise therewith, when limit level is risen to, the driving member on magnetic floating block can pass through the fortune that driving member is risen by transmission component Dynamic transmission is motion of the impeller towards the first opening direction so that impeller stretches out the first opening and carrys out pushing power switch so that The elevated situation of stopping liquid level being reached, practicality is increased.

This utility model is further arranged to：The impeller be push pedal, the driving member be projection, the transmission component Include the first groove being arranged in the push pedal, the first wedge surface being arranged on first groove, be arranged at it is described convex The second wedge surface being engaged with first wedge surface on block and the return unit for the push pedal is resetted.

By adopting above-mentioned technical proposal, when the liquid level in Raw material pail is constantly raised, the magnetic floating block on liquid level also can Rise therewith, when the height of the upper limit is risen to, the projection of magnetic floating block can by the cooperation of the first wedge surface and the second wedge surface come So that the motion transmission by projection upwards is the motion to push pedal forward so that one end pushing power switch that push pedal is moved forward So as to turn off the power switch so that liquid level does not continue to raise, after liquid level is reduced, push pedal can be due to the effect of return unit certainly It is dynamic to reset, increased practicality and convenience.

This utility model is further arranged to：The return unit be back-moving spring, one end of the back-moving spring with it is described Push pedal is fixedly connected away from one end of the first opening, and the other end of the back-moving spring is fixedly connected with the Raw material pail inwall.

By adopting above-mentioned technical proposal, after the liquid level in Raw material pail declines, magnetic floating block also can be with liquid level Drop, projection can also reduce to the active force of push pedal, so as to cause the pulling force of back-moving spring more than projection for the effect of push pedal Push pedal is automatically reset, practicality is increased.

This utility model is further arranged to：The transmission component is included and is horizontally set in Raw material pail and with described the The housing of one open communication and the second opening located at housing lower surface, the impeller is outline and the inner walls Size identical first piston, the first piston are connected with the housing sliding, and the first piston is near the first opening First piston bar is provided with simultaneously, the driving member is and the second openings of sizes identical second piston, on the magnetic floating block Second piston bar is provided with, second piston is fixedly connected with the second piston bar away from the one side of the second opening.

By adopting above-mentioned technical proposal, when liquid level is constantly raised, magnetic floating block can be driven to rise, so as to second piston Can by second opening extend in housing, due to the outline of first piston it is identical with inner walls size, so first work Sealing space can be formed between plug and second piston, when second piston continues to stretch into, second piston can carry out the pressure to air Contracting, so as to first piston can be driven to move so that the First piston bar being connected with first piston can stretch out the first opening and by Piezoelectricity source switch such that it is able to which on and off switch is closed so that liquid level is not continuing to raise, and increased practicality.

This utility model is further arranged to：The First piston bar is arranged at the center of the first piston, described Second piston bar is arranged at the center of the second piston.

By adopting above-mentioned technical proposal, as first piston and second piston are elastomeric material, if so first lives Stopper rod and second piston bar can cause first piston and respectively to first piston and the discontinuity of second piston Two piston portions bend, and so as to carry out the compression to air well, increased practicality.

This utility model is further arranged to：Be provided with first opening and push, it is described push on be provided with and be hinged Part, described pushing are hinged with the Raw material pail by articulated elements.

By adopting above-mentioned technical proposal, the setting at the first opening pushes and is prevented from dust in Raw material pail, and And when push pedal is moved, can push open and push to touch on and off switch, when push pedal resets, pushing can be multiple by articulated elements Position, increased practicality and convenience.

This utility model is further arranged to：The articulated elements is spring hinge.

Spring reset can be passed through after opening, increased practicality by adopting above-mentioned technical proposal, spring hinge.

In sum, this utility model has the advantages that：This utility model has practicality and convenience.
