Description
Technical field：
The utility model is related to a kind of pointer magnetic coupling component of the circular magnet steel flow instrument of quadrupole.
Background technology：
Float-type indicating meter is to include a flow tube separately plus by pointer, dial, indicator this is two big
Part is combined；There is one with magnetic float, when fluid flows are measured in buret, flow in flow tube
Size variation can make float that position movement change occur therewith, in addition equipped with " pointer on the needle pivot inside gauge outfit
Magnetic coupling component " is used as throw of pointer power；One " displacement movement " that float is produced in measurement pipe is former by magnetic coupling
Reason drives the pointer in gauge outfit to occur the changes in deflection synchronous with float to realize the size of instruction flow.In existing reality
In the product used, the structure and principle of pointer magnetic coupling component are：Needle pivot is installed perpendicular to gauge outfit base plate plane, this
Gauge outfit is close and is fixed on equipped with float measurement pipe（Meet within the certain magnetic line of force strength range of float magnet steel）, now float
When son is subjected to displacement variation, pointer will produce deflection, and gauge outfit serves instruction flow and become with regard to that can read the reading of dial
The effect of change.
Current pointer magnetic coupling component be one piece of special circular aluminium block be fitted with 2 sections with float inside magnet steel it is different
The small magnet steel of the attracting magnetic pole of property, the making of this pointer magnetic coupling component is complex, and installation and debugging are cumbersome;First two segments
Oblique cutting is and glued with epoxy resin in circular aluminum magnetic coupling package base at an angle for magnet steel, in addition respectively two
Two screw rods are installed with dynamic balancing is made adjustments in 180 ° of sides of segment magnet steel position again, and then whole pointer coupling assembly is fixed
Active balance is adjusted on to needle pivot, then fixes dynamic balancing adjusting screw with adhesive can just begin to use.The design due to
Widget is too many, not only makes trouble, and such as impacted in use or use time it is longer after, adjusting screw
Situations such as loosening, which easily occurs, in position or adhesive aging comes off causes balance destroyed or even magnet steel drops, finally make whole instrument
Table can not be used normally.In the event of magnet steel drop or dynamic balancing it is destroyed when whole instrument must be from using scene
Disassembling could recover to use after readjusting.
The content of the invention：
Technical problem to be solved in the utility model is：The pointer magnetic coupling group that a kind of precision is high and need not debug is provided
Part.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：A kind of quadrupole is circular
There is through hole centered on the pointer magnetic coupling component of magnet steel flow instrument, including magnet steel, needle pivot and package base, the magnet steel
Cylindrical structure, and magnet steel both ends of the surface are divided into the opposite polarity of four magnetic poles and two neighboring magnetic pole, the component
Base central opens up and is provided with annular groove, the magnet steel on the through hole installed for needle pivot, the outer wall of the package base
In the annular groove for being sleeved on package base outer wall, the needle pivot is fixedly installed in the through hole of package base center, institute
Package base is stated by the way that magnet steel, needle pivot are arranged on into single injection-molded in mould, and the needle pivot is in magnet steel
Concentric position.
Preferably, being arranged concentrically circular groove at the top of the magnet steel.
Compared with prior art, usefulness of the present utility model is：This product is placed using quadrupole magnet steel with needle pivot
The mode of integrated injection molding in mould, it has the advantages that processing precision is high and need not debug, while also having life
Production is convenient, technique not only simple products yield rate but also high advantage, and the durability of product has significant improvement in addition, it is to avoid
Situation about being debugged again is needed because interiors of products structure is subjected to displacement, most importantly the material cost of product and artificial
Cost has great reduction so that production capacity and benefit have obvious growth.
Brief description of the drawings：
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the structural representation of magnet steel.
In figure：1st, magnet steel；2nd, needle pivot；3rd, package base.
Embodiment：
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment：
A kind of pointer magnetic coupling component of the circular magnet steel flow instrument of quadrupole as depicted in figs. 1 and 2, including magnet steel 1, refer to
There is the cylindrical structure of through hole centered on needle shaft 2 and package base 3, the magnet steel 1, and the both ends of the surface of magnet steel 1 are divided into
The opposite polarity of four magnetic poles and two neighboring magnetic pole, traditional product structure is provided with two magnetic poles, using four magnetic pole magnet steel 1
Purpose be for the magnetic field intensity all same of 1 four sector regions of magnet steel, therefore have the advantages that without debugging, described group
The center of part pedestal 3 opens up and is provided with annular groove on the through hole installed for needle pivot 2, the outer wall of the package base 3, described
Magnet steel 1 is sleeved in the annular groove of the outer wall of package base 3, and the needle pivot 2 is fixedly installed on the logical of the center of package base 3
In hole, the package base 3 by magnet steel 1, needle pivot 2 by being arranged on single injection-molded in mould, and the needle pivot 2
Concentric position is in magnet steel 1, magnet steel 1, needle pivot 2 are fixed in the mould being molded for package base 3, magnet steel 1, pointer
Axle 2 constitutes complete injection mold cavity with injection mold, and then obtains integrally formed with magnet steel 1, needle pivot 2 and package base 3
Structure, therefore this product has the advantages that product has durability strong.
The top of magnet steel 1 has been arranged concentrically circular groove, during injection, the upper surface insertion of package base 3
Into the circular groove at the top of magnet steel 1, and then it can reach the upper plane of package base 3 and the effect of the either flush of magnet steel 1, it is to avoid
It is in other assemblies assembling process to interfere because of plane protrusion in package base 3.
This product is placed in mould by the way of integrated injection molding using quadrupole magnet steel and needle pivot, and there is processing to give birth to for it
Produce precision high and without the advantage of debugging, while also there is convenient for production, technique not only simple products yield rate but also high advantage, this
The durability of outer product has significant improvement, it is to avoid because being subjected to displacement interiors of products structure need to be debugged again
Situation, the material cost and cost of labor of most importantly product have great reduction so that production capacity and benefit have
It is obvious to increase.
It is emphasized that：It the above is only preferred embodiment of the present utility model, not the utility model appointed
What formal limitation, every any simple modification made according to technical spirit of the present utility model to above example, etc.
With change and modification, in the range of still falling within technical solutions of the utility model.
