Fig. 2 is the structural representation of the another kind of connecting rod Balance Control of constant magnetic field variation monitoring alarming instrument of the present invention mechanism.
Embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing constant magnetic field variation monitoring alarming instrument of the present invention.
As shown in Figure 1, constant magnetic field variation monitoring alarming instrument of the present invention comprises housing 1, is provided with 2 connecting rods 3 that rotate around the shaft in housing 1, is fixed with first magnetic patch 4 at connecting rod 3 middle parts, and connecting rod 3 is by connecting rod Balance Control mechanism controls.At least be provided with one section warning guide rod 6 on the connecting rod 3, warning guide rod 6 adopts conductor material to make, be connected with the positive pole or the negative pole of warning circuit 8 on the warning guide rod 6, be provided with wire column 7 in warning guide rod 6 both sides, another electrode of this warning circuit 8 is electrically connected with wire column 7.
As shown in Figure 1, connecting rod Balance Control mechanism is that an end and the housing 1 of first spring, 51, the first springs 51 is fixing, and the other end is connected with connecting rod 3, and connecting rod Balance Control mechanism also can be the shell fragment (figure does not draw) that is arranged in an opposite side certainly.First magnetic patch 4 is positioned at the middle part of connecting rod 3, is provided with second magnetic patch 41 in the end of connecting rod 3, in the second magnetic patch arranged outside the first iron plate frame 91 is arranged.Constant to the right the time when magnetic direction, place this constant magnetic field variation monitoring alarming instrument as figure and get final product.First magnetic patch 4 is subjected to magnetic field force to the right under the effect in magnetic field, connecting rod 3 has reached balance under the effect of first spring 51 (or shell fragment) at this moment.Second magnetic patch 41 just in time is positioned at the first iron plate frame, 91 centre positions, and second magnetic patch 41 is opposite with magnetic field force equal and opposite in direction and direction between the first iron plate frame, the 91 both sides frames.Each acting force that acts on like this on the connecting rod 3 is cancelled out each other, and connecting rod 3 is in equilibrium state.When magnetic field intensity and magnetic direction changed, the magnetic field force that first magnetic patch 4 is subjected to made connecting rod 3 deflections, and warning guide rod 6 contacts with wire column 7, warning circuit 8 conductings.When magnetic direction during, only need get final product opposite of " N " utmost point with magnetic direction with first magnetic patch 4 in this constant magnetic field variation monitoring alarming instrument to other directions.
When change of magnetic field strength little, though connecting rod 3 deflects, but when warning guide rod 6 can not contact with wire column 7, second magnetic patch 41 departs from the first iron plate frame, 91 centre positions, cause the magnetic field force size between second magnetic patch 41 and the first iron plate frame, the 91 both sides frames unequal, second magnetic patch 41 is under the attraction of the first iron plate frame 91, rapidly to a side shifting of the first iron plate frame 91, warning guide rod 6 also can contact with wire column 7 like this, warning circuit 8 conductings.
As shown in Figure 2, first magnetic patch 4 also can be positioned at the end of connecting rod 3, is provided with the balanced body 42 that is used for balanced connecting rod 3 at the other end of connecting rod 3, and according to lever principle, connecting rod 3 is in equilibrium state.
For solve because of change of magnetic field strength little, though connecting rod 3 deflects, but the problem that warning guide rod 6 can not contact with wire column 7, balanced body 42 is made for magnetic material, in balanced body 42 arranged outside the second iron plate frame 92 is arranged, can realize that equally change of magnetic field strength is little, the function of warning circuit 8 conductings.
In order when this constant magnetic field variation monitoring alarming instrument is put into the stationary magnetic field connecting rod 3 to be regulated, housing 1 is provided with transparent detecting window 11, is provided with index dial 12 in the detecting window side.Certainly, in order to observe convenient, as shown in Figure 2, be fixed with the pointer 31 that together rotates with connecting rod 3 in rotating shaft 2, detecting window 11 and index dial 12 are positioned at pointer 31 places.
Connecting rod 3 is provided with lever regulated mechanism, is used for connecting rod 3 is adjusted to suitable position.Lever regulated mechanism can be as shown in Figure 1, for stretch out housing 21 and can regulate first spring 51 adjusting button 14.Lever regulated mechanism also can be provided with second spring 15 as shown in Figure 2 between housing 21 and connecting rod 3, adjusting button 14 stretches out housing 21 and is connected with second spring 15.Lever regulated mechanism also can regulate line for rotating, this rotation is regulated the line two ends and is fixed on the connecting rod 3, and the centre is wrapped in to regulate on the button 14 and gets final product, certainly, lever regulated mechanism also can be other known governor motions, as long as connecting rod 3 can be adjusted to correct position.
According to the magnetic field intensity difference of being monitored, this constant magnetic field variation monitoring alarming instrument can be provided with different models, promptly use the spring 51 (or shell fragment) of different elastic strengths or the balanced body 42 of use Different Weight.So just can select the constant magnetic field variation monitoring alarming instrument of different model according to the magnetic field intensity of varying strength for use.According to the magnetic direction difference of being monitored, can design the different guard against theft and alarm system of pole orientation of first magnetic patch 4, like this, use the guard against theft and alarm system of the first different magnetic patch 4 of pole orientation to get final product at the different magnetic field direction.
During use, select the constant magnetic field variation monitoring alarming instrument of suitable types, this constant magnetic field variation monitoring alarming instrument is placed magnetic field to be monitored, regulate button 14, make connecting rod 3 just in time be in index dial 12 middle scale positions, open warning circuit 8, when magnetic field intensity or direction variation, connecting rod 3 deflections, warning guide rod 6 contacts with wire column 7, warning circuit 8 conductings realize warning function.
