Abstract
To provide a switching mechanism of which an equipment need not be made large in size nor complicated, and much less, a permanent magnet which may affect a sensor or the like need not be carried about for operation of the equipment. Switching of operation in the equipment 1 is carried out by a reed switch 3 provided inside the equipment 1 sensing a given magnetic field. The reed switch 3, provided with reed relays 4, 5, senses the given field base on magnetic induction and closes contacts of the reed relays 4, 5. The switching mechanism arranges a permanent magnet 7 and a ferromagnet 8 inside the equipment 1, in a state having the reed switch 3 not sense the given field, that is, so as not to induce magnetic induction. As a user brings another ferromagnet (a ferromagnet for operation) 9 near the permanent magnet 7 or the ferromagnet 8 from outside the equipment 1, the magnetic induction is induced to the reed switch 3 to close the contacts of the reed relays 4, 5, which makes it possible to operate the equipment.

Description
Technical field
The machine that the present invention relates to switching mechanism and possess this switching mechanism, be particularly suitable in more detail being installed in and be set at the switching mechanism that switch the operation of machine in the next door of passing through machine on the outdoor machine, and the machine that possesses this switching mechanism.
Background technology
The operation of on various machines variety of way or parameter being set is normally undertaken by guidance panel or single switch.When needing waterproof in outdoor grade, when explosion-proof place is provided with machine,, switches the switch in the machine and machine is operated by the next door of machine.
Fig. 6 is the schematic diagram of example of a formation of the switching mechanism used of the outdoor machine of conventional art.In Fig. 6, the explanation of symbol is as follows respectively: 41 expression machines, 42 expressions are as the next door of the shell of machine 41, next door, 47 expression percussive buttons, 48 expression springs, the 49 expression permanent magnets that 43 expression reed switch, 44,45 are represented reed relay, 46 expression switch portion.
On the next door 46, the switching mechanism that is made of reed switch 43 and percussive button 47 is set.On the reed switch 43 of this switching mechanism, equip a pair of reed relay 44,45 (switch disconnection) with notconnect state, connection makes switch conduction after the effect in the magnetic field of reed relay 44,45 induced magnets regulation.For produce/cancellation can make the magnetic field of the regulation of reed relay 44,45 action, in the inside of percussive button 47 permanent magnet 49 is installed.After the percussive button pressed towards the direction of the ON of arrow side, permanent magnet 49 was to reed switch 43 side shiftings, the influence in the magnetic field of reed relay 44,45 induction permanent magnets and conducting.Percussive button 47 can be fixed on the position of the regulation corresponding with the ON/OFF mark of arrow by spring 48 and hook (scheming not shown).The position of so-called here regulation is meant two positions at interval of leaving that can distinguish the connection/non-connection of the reed relay 44,45 of inductive switch ON/OFF, promptly, by the influence in the magnetic field of permanent magnet 49, the position that reed relay 44,45 can be connected with because the influence in magnetic field reduces the position that makes that reed relay 44,45 can not be connected.Perhaps also can adopt and not use hook, press the button 47 and make switch conduction, take away the hand that presses the button then,, make button 47 return to original position, the form that switch is disconnected by the effect of spring with hand.Under this form, whenever press button 47 next time, switch conduction carries out the operation of machine.
Make as operational elements at such permanent magnet under the situation of switching mechanism of reed switch action, the magnetic hysteresis of the ON/OFF of reed switch is big, and this just requires the shift motion of its permanent magnet also big.Therefore, the structure of machine is just big and complicated.
Fig. 7 is that other of the switching mechanism used of the outdoor machine of technology in the past constitute the schematic diagram of examples.In Fig. 7, the explanation of symbol is as follows respectively: 51 expression machines, 52 expressions are as the next door of the shell of machine 51, next door, the 59 expression permanent magnets that 53 expression reed switch, 54,55 are represented reed relay, 56 expression switch portion.
On the next door 56, the switching mechanism that is made of reed switch 43 is set.On the reed switch 53 of this switching mechanism, equip a pair of reed relay 54,55 (switch disconnection) with notconnect state, reed relay 44,45 is subjected to connecting after the effect in magnetic field of magnet regulation and makes switch conduction.For produce/cancellation can make the magnetic field of the regulation of reed relay 44,45 action, the user moves to the assigned position of reed switch 53 sides (the ON direction that arrow is represented) with permanent magnet 59, or to opposition side (direction of the OFF that arrow is represented) avoiding switching 53.In this configuration example, at every turn by permanent magnet when reed relay 54,55 being formed connect, switch conduction further carries out machine operation.Here so-called assigned position is meant the link position of reed relay 54,55, i.e. the position that reed relay 54,55 is exerted an influence by the magnetic field of permanent magnet 159.
Such permanent magnet be not assembled under the situation of the switching mechanism in the machine construction, because the magnetic that permanent magnet self has might be to other the bad influences of generation such as transducer.Promptly when permanent magnet is assembled in machine intimate, can consider in advance owing to the influence of permanent magnet other transducer, and when permanent magnet is not assembled in the machine, because the user might make permanent magnet freely move, the user particularly might make permanent magnet near the place beyond the switching mechanism, perhaps near other machine.At this moment, just be difficult to avoid the influence of permanent magnet to other transducers etc.And then the user also may perhaps need to hold away at other place keeping permanent magnet.Even permanent magnet does not pass the zone that may influence other transducer, hand-held also inconvenience of moving itself.

Embodiment
Switching mechanism of the present invention is the magnetic field induction device that possesses the magnetic field of induction regulation at machine intimate, the mechanism of the operation of this machine being switched by the magnetic field induction device.In the present invention, so-called machine is while except the user observes the machine of the switching that operation display part operates, also comprise the switching device that the remote operation of some device is used.And in the present invention, so-called magnetic field induction device is according to the device in the magnetic field of magnetic induction induction regulation, does not expose outside machine, and disposes by the next door of machine.Below several embodiments of the present invention are described, but the invention is not restricted to following embodiment.
At first, as one embodiment of the invention, the embodiment as the reed switch of magnetic field induction device describes to use.Fig. 1 is the figure of the switching mechanism of this embodiment of expression, and Fig. 2 is the figure for the switch motion of the switching mechanism of key diagram 1.Symbol among the figure is represented respectively: 1-machine, 2-are as other ferromagnetism body (operation ferromagnetism body) of the next door of the next door of the shell of machine 1,3-reed switch, 4,5-reed relay, 6-switch portion, 7-permanent magnet, 8,8 '-ferromagnetism body, 9-.
In the present embodiment, 6 configurations of the next door by switch portion are as the reed switch 3 of magnetic field induction device.Also in the inside of machine 1 with the state configuration ferrite permanent-magnet iron 7 and the ferromagnetism body in the magnetic field that in reed switch 3, can not respond to regulation, that is, make it in reed switch 3, can not cause magnetic induction.In addition, permanent magnet 7 and ferromagnetism body 8 also can be configured on the outer wall.
In the present embodiment, the operation else that the user will be different with ferromagnetism body 8 near permanent magnet 7 and ferromagnetism bodies 8, causes magnetic induction (magnetic induction phenomenon) with magnetic 9 on reed switch 3, carry out the switching of machine operation.Promptly, in switching mechanism of the present invention, near magnet, but the operation that makes it near pure iron, iron, yoke etc. makes reed switch 3 actions with ferromagnetism body 9 unlike above-mentioned prior art, and the operation of carrying out machine 1 according to the magnetic field of induction on the reed switch 3 is switched.By making operation make the magnetoimpedance of reed relay 4,5 of reed switch 3 reduce near permanent magnet 7 and ferromagnetism body 8, also we can say to form suitable flux path (magnetic circuit) with ferromagnetism body 9.In addition, permanent magnet 7 and ferromagnetism body 8 will dispose to such an extent that make it when not operation, and ferromagnetism body 8 can not magnetized by permanent magnet 7, but preferably consider its variation to the influence of reed switch 3.
But operation will have necessary near distance from permanent magnet 7 at least with ferromagnetism body 9, with the reed relay 5 that forms permanent magnet 7, operation ferromagnetism body 9, ferromagnetism body 8, reed switch 3, the circulation magnetic circuit that reaches reed relay 4.In addition, consider that operation has some skews also can not cause overslaugh with the position of ferromagnetism body 9, just is readily appreciated that also this operation does not need very accurate reason in order to form above-mentioned magnetic circuit.And, in the present embodiment, it is suitable that operation himself is not magnetized with ferromagnetism body 9, even but operation has been magnetized with magnetic, perhaps replace and adopt the operation permanent magnet, as long as can adjust near the time the basis of position on adjust magnetic polarity towards, on reed switch 3, also can cause magnetic induction.And employed operation there is no need other preparation with ferromagnetism body 9, can utilize some contiguous iron plate, the instrument of driver etc. can constitute the various article of magnetic circuit, therefore easily.And, in the present embodiment, rely on the magnetizing force of permanent magnet 7, replace ferromagnetism body 8 and operation a side or two aspects with ferromagnetism body 9, use weak magnetic substance also can.
The switch motion of the switching mechanism of present embodiment is described below with reference to Fig. 2.On the next door 6, the switching mechanism that setting is made of reed switch 3, permanent magnet 7 and ferromagnetism body 8, reed switch 3 is equipped with a pair of soft magnetic metal sheet (the reed relay wine cup of soft-magnetic body) 4,5 as contact (switch disconnect, with reference to Fig. 2 (A)) with notconnect state.In the present embodiment, connect after reed relay 4,5 is sensed the magnetic field of operation with the regulation of ferromagnetism body 9, switch becomes connection (with reference to Fig. 2 B).In order to produce/magnetic field of this regulation of cancellation, the user will operate with ferromagnetism body 9 and move to reed switch 3 sides and be configured on the assigned position, or move to opposition side, avoid from reed switch 3.Whenever using 8 switch connections of ferromagnetism body near operating, the operation of machine is pushed ahead.Here so-called position is the position that connects reed relay 4,5, in other words, is meant to form because operation approaching with ferromagnetism body 9 magnetic circuit (representing with thick arrow) to the influence of reed relay 4,5 that can be showed by magnetic field.In this embodiment, permanent magnet 7 is configured in a side the side of the reed relay 4,5 of reed switch 3, ferromagnetism body 8 is configured in the another side, and the user will be by operating from the outside of machine 1 with ferromagnetism body 9 near near the control of carrying out switching manipulation on the line that links permanent magnet 7 and ferromagnetism body 8.
On the other hand, as reed switch 3, when what use is as two reed relay 4,5 of contact during with the reed switch of the type of being opened its contact by user's operation with ferromagnetism body 9 approaching, also can by permanent magnet 7 or other permanent magnets its contact be closed in advance, give to reciprocal magnetic field with the approaching of ferromagnetism body 9 by operation, unborn magnetic field is removed and open contact.
According to present embodiment, machine 1 in outdoor setting, the transducer of transducer of using such as flowmeter etc. is such must have under the situation of machine 1 in the next door that waterproof anti-explosion uses, operation that also can be by the general iron plate that can not impact other transducer, bar-shaped iron, general electromagnetic steel plate etc. is carried out the handover operation of machine with ferromagnetism body 9.The action of general reed switch is to utilize magnet substantially, according to present embodiment, can not adopt the mode that moves the magnet that may impact other transducer etc. and makes reed switch 3 actions.And then according to present embodiment, with permanent magnet 7 with such as pack into 1 li in machine of the such ferromagnetism body 8 of iron, therefore the parts that constitute are simple again less, and are also favourable on cost, and move simple.The effect of its magnetic force of the permanent magnet that is fixed in reed switch 3 is not make the state configuration of these switch 3 actions, by will operate with ferromagnetism body 9 near making it to produce magnetic flux, reduce the magnetoimpedance of 4,5 of reed relay and make reed switch 3 actions.If flow shape is used transducer, can utilize the switching mechanism of present embodiment that display mode and the set-up mode that is arranged on outdoor stored count device switched, also can switch the flow display mode in the display mode, flow velocity display mode etc.
And, in Fig. 1 and Fig. 2 (A), (B), though in order to simplify the manufacturing process of machine 1, do permanent magnet 7 and ferromagnetism body 8 big or small on an equal basis as shown in the figure, but in the present embodiment, such as shown in Fig. 2 (C), also can replace ferromagnetism body 8 and adopt easier magnetized bigger ferromagnetism body or configuration ferromagnetism body 8 near the reed relay 5 of reed switch 3.At this moment, if other condition, such as magnetism intensity, the position of permanent magnet 7, employed ferromagnetism body 8 (8 '), character of 9 etc. are identical, also can move (with reference to Fig. 2 (B), (C)) near reed switch 3 very much even will not operate with ferromagnetism body 9.Like this, permanent magnet 7 can be the same big or small with the ferromagnetism body 8,8 ' of the machine intimate of packing into, also can vary in size, but preferably adjust configuration, so that the sensitivity of raising reed switch 3 to these sizes, distance and to reed switch 3 and these distance.In addition, also can be weak magnetic substance as described above about ferromagnetism body 8 '.
And as other embodiments of the invention, in the inside of machine 1, replacement ferromagnetism body 8 reinstalls a permanent magnet and also can receive same effect.But this situation is considered the magnetic pole of two permanent magnets, and must make when making machine 1 by operation becomes possibility with the switch motion of the reed switch 3 of ferromagnetism body 9.Such as, adopt the position relation shown in Fig. 2 (A) to describe, replace the magnetic pole of permanent magnet 7 and ferromagnetism body 8 and the magnetic pole of the permanent magnet of configuration should be reciprocal up and down for well.
And, as other embodiments of the invention, also can not use ferromagnetism body 8, only, so also can obtain effect same at the internal configurations permanent magnet 7 of machine 1.Specifically be, as long as the side that permanent magnet 7 is configured in two reed relay 4,5 of reed switch 3 just can.Below omit the detailed description to this embodiment, under the situation that only disposes permanent magnet 7, basic consideration method should be noted the configuration place of the permanent magnet 7 of reed switch 3 too.Particularly, if with permanent magnet 7 with the state configuration in the magnetic field that in reed switch, can not respond to regulation on machine intimate or outer wall, can not cause in reed switch 3 that promptly configuration is just passable in electromagnetic induction.
In addition, the user will operate with ferromagnetism body 9 near permanent magnet 7 from the outside of the machine 1 of setting, particularly, to operate a side's who uses ferromagnetism body 9 side near reed relay 4, the opposing party's side near reed relay 5, is caused that on reed switch 3 magnetic induction carries out machine operation.But operation is identical with initial embodiment with ferromagnetism body 9, must be sufficiently approaching with permanent magnet at least, so that form permanent magnet 7, operation circulation magnetic circuit with the reed relay 5 of ferromagnetism body 9, reed switch 3, same reed relay 4.In addition, consider that forming such magnetic circuit can just not understand this operation yet and there is no need with accurate parts easily owing in operation owing to the offset that has certain operations with ferromagnetism body 9 causes damage.And, even the parts that the operation in the operation is magnetized with ferromagnetism body 9, as long as near when the basis of position on, the direction of magnetic pole is adjusted, on reed switch 3, also can cause magnetic induction.
