Abstract
The utility model relates to a bistable state needle selection electromagnetic valve, which comprises an electromagnetic valve seat, permanent magnets, two coil frameworks and two long strip-typed iron cores, wherein the two long strip-typed iron cores are respectively inserted in iron core insertion grooves of the two coil frameworks. The bistable state needle selection electromagnetic valve is characterized in that the number of the permanent magnets is two, the two permanent magnets are fixedly arranged on the electromagnetic valve seat, and the inner sides of both ends of the two long strip-typed iron cores are pasted and arranged on the sides of the two permanent magnets. The utility model has the advantages that: the upward and downward movement of the two coil frameworks is only controlled through the effect of the two permanent magnets, the iron cores and the coils, and the hole and hole-free tasks are completed, so the two permanent magnets can be omitted, the production cost of enterprises is reduced, and the industry can be fast developed favorably.
Description
[technical field]
The utility model relates to a kind of bistable state needle selection electromagnetic valve that uses on jacquard.
[background technology]
Bistable state needle selection electromagnetic valve is actually the needle selecting device that is made of mechanical cylindrical fireworks, magic flower mechanism and card on the mechanical jacquard of a kind of alternative tradition.China Patent No. 031439950 relates to bistable state needle selection electromagnetic valve " (hereinafter to be referred as electromagnetic valve).It is a kind of electromagnetic valve of voice coil motor formula, and its structure is made of solenoid valve seat, coil rack, coil, iron core, permanent magnet.Have horizontal pilot hole and vertical special-shaped groove on the solenoid valve seat, one end of coil rack has block, the other end to have terminals, centre that one through hole is arranged, iron core is placed in the through hole of coil rack, permanent magnet is close on two relative faces of iron core, with respect to same iron core, the magnetic pole of the permanent magnet that pastes mutually is identical with it, and the excitation system that iron core and permanent magnet are formed is fixed in the vertical special-shaped groove of solenoid valve seat.But coil rack moves with respect to the iron core easy on and off, one end of flexible circuit is fixed on the terminals of coil rack, one end is fixed on the substrate and is connected with the control circuit of computer output, and coil is on coil rack, and its lead-in wire is connected with the end of flexible circuit at terminals.We can say the appearance of this electromagnetic valve, changed the needle selection mode of traditional jacquard, thereby greatly advanced the fast development of textile industry.
But, there are the following problems in actual applications for the electromagnetic valve of said structure: in each electromagnetic valve except that two coils, two coil racks, two pieces of strip shape iron cores etc. are set, four permanent magnets need be set, because permanent magnet relates to rare earth resources, so price height, both increase the production cost of enterprise, also be unfavorable for the fast development of this industry.
[summary of the invention]
For overcoming above-mentioned defective, the utility model aims to provide a kind of bistable state needle selection electromagnetic valve, and this electromagnetic valve has advantage simple in structure, that production cost is low on the basis of realizing identical function.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this bistable state needle selection electromagnetic valve, comprise solenoid valve seat, permanent magnet, two coil racks and two pieces of strip shape iron cores, two pieces of strip shape iron cores are inserted in respectively in the iron core slot of two coil racks, it is characterized in that: described permanent magnet is two, be fixedly installed on the described solenoid valve seat, the inboard at two pieces of strip shape iron core two ends posts on the side of two blocks of permanent magnets.
Beneficial effect: compared with prior art, the utility model is only used the effect of two permanent magnets and iron core, coil, moving up and down of two coil racks of control, finish " porose " and " atresia " task, thereby can omit two permanent magnets, reduce enterprise's production cost, helped the fast development of this industry.
, by embodiment the utility model is further described below in conjunction with accompanying drawing.
[description of drawings]
Accompanying drawing is the assembly structure schematic diagram of an embodiment of the utility model.During installation, coil rack 301 need turn 90 degrees by revolving shown in the arrow P among the figure among the figure.
Among the figure: solenoid valve seat 300, steady pin 3001, permanent magnet installation place 3002, iron core installed surface 3003, solenoid valve seat stationary plane 3004, alignment pin 3005, screw 3006; Coil rack 301, catch 3011, soft row's brace 3012, soft row's fixed leg 3013, iron core slot 3014; Iron core 302, permanent magnet 303.
[specific embodiment]
Referring to accompanying drawing.The application's electromagnetic valve comprises the permanent magnet 303 of a solenoid valve seat 300, two coil racks 301, two pieces of iron cores 302, two branch N, the S utmost point.Described permanent magnet 303 is two, is fixedly installed on up and down in the permanent magnet installation place 3002 of described solenoid valve seat 300, and the inboard at two pieces of strip shape iron core 302 two ends posts on the side of two blocks of permanent magnets 303.Have catch 3011, soft row's brace 3012 on two coil racks 301 respectively, soft row's brace 3012 is provided with soft row's fixed leg 3013.For solenoid valve seat 300 is fixed on the substrate by solenoid valve seat stationary plane 3004, soft row's brace 3012 is arranged on the same side with catch 3011, is positioned at a relative side of solenoid valve seat stationary plane 3004.During assembling, be pedestal with solenoid valve seat 300, permanent magnet 303 is arranged on earlier in the corresponding permanent magnet installation place 3002, and two pieces of iron cores 302 are inserted in respectively in the iron core slot 3014 of two coil racks 301, are assembled into integral body.Coil connectors is connected on the circuit of substrate by flexibly connecting line through soft row's brace 3012.
