Specific embodiment

Below in conjunction with the accompanying drawings this utility model is further described.

A kind of core assembly as shown in Figures 1 to 7, including plunger tube 1, dynamic iron core 2 and static iron core 3, inside plunger tube 1 From top to bottom string is provided with dynamic iron core 2, static iron core 3 and ratchet assembly successively, and ratchet assembly includes ratchet parent 4, presses wheel 5, runner 6 And elasticity reset device, ratchet parent 4 is fixed on the inside of plunger tube 1, presses wheel 5 and runner 6 is axially moveable is installed in ratchet In parent 4, and press wheel and 5 engage with runner 6.

Dynamic iron core 2 is passed through ejector pin 8 and is pressed wheel 5 and offset cooperation, be additionally provided with ratchet parent 4 for press take turns 5 and runner alter about 6 Dynamic muscle groove 41, specifically, press wheel 5 be provided with muscle groove 41 cooperation press wheel convex tendon 51；Runner 6 is provided with and muscle groove 41 cooperation Runner convex tendon 61.There is in muscle groove 41 primary importance 411 locking in low level for runner 6, for pressing wheel 5 the second of high-order locking Position 412；

Elasticity reset device coordinates with runner 6 transmission it is preferable that elasticity reset device is back-moving spring 7, back-moving spring 7 Upper end and runner 6 offset cooperation, back-moving spring 7 is used for applying towards pressing the elastic acting force taking turns 5 directions to runner 6.

Operation principle of the present utility model is:

When dynamic iron core 2 is promoted by ejector pin 8 under electromagnetic force and presses wheel 5, promote runners 6 along muscle groove 41 by pressing wheel 5 Play downwards, in the starting stage of motion, press wheel 5 outer walls setting press that wheel convex tendon 51 makes to press wheel 5 will not be with respect to ratchet mother Body 4 rotates, and runner convex tendon 61 also makes runner 6 will not rotate with respect to ratchet parent 4, when runner 6 moves to neighbouring first When putting 411, rotation stop event resolves between runner 6 and ratchet parent 4, runner 6 will because with the engagement pressing wheel 5 and turn Dynamic, so that the runner convex tendon 61 of runner 6 outer wall and muscle groove 41 is misplaced, after runner 6 turns an angle, if the coil of now electromagnetic valve Assembly power-off, due to the pushing and pressing effect of back-moving spring 7, runner 6 is just snapped into primary importance 411, so that runner 6 position Locked；

When dynamic iron core 2 promotes again by ejector pin 8 under electromagnetic force and presses wheel 5, runner 6 can be again with respect to ratchet Parent 4 rotates so that the runner convex tendon 61 of runner 6 outer wall is alignd with muscle groove 41 relevant position, if now coil block power-off, multiple Position spring 7 will promote runner 6 and press wheel 5 and be synchronized with the movement to, making to press wheel 5 in situ and be locked in the second position 412, due to moving ferrum Core 2, ejector pin 8, press wheel 5, runner 6 and back-moving spring 7 and offset successively, thus now runner 6 also with press wheel 5 corresponding positions Locked.

In sum, compared with prior art, this utility model operationally need not make the long-time energising of magnet exciting coil just The locking in diverse location for the runner 6 can be realized, thus during installing and using, when the valve port cooperation of runner 6 and electromagnetic valve During work, just valve port can be made to maintain a normally open the work of (or normally closed) in the case of need not making the long-time energising of magnet exciting coil State, energy-saving effect preferably, is conducive to extending the service life of electromagnetic valve.This utility model is simple and reasonable, easy to use, Stable work in work, reliability.

Static iron core 3 is provided with tapered protrusion portion 31 near the end of dynamic iron core 2, and the respective end of dynamic iron core 2 is provided with and taper The taper groove portion 21 that lobe 31 matches.By arranging said structure, effectively increase electromagnetic induction value of the present utility model, Thus reducing the startup power of electromagnetic valve, energy-saving effect is more preferable.

Support between the top of dynamic iron core 2 and plunger tube 1 and be provided with power assistant spring 9, power assistant spring 9 is used for making dynamic iron core 2 have Movement tendency towards static iron core 3 direction.By arranging power assistant spring 9 so that dynamic iron core 2 has certain initial work to ejector pin 8 Firmly such that it is able to reduce the number of turn of electromagnetic valve magnet exciting coil, reduce the manufacturing cost of electromagnetic valve.

The outer wall of ratchet parent 4 is provided with the raised line 42 with plunger tube 1 close-fitting, by arranging raised line 42, effectively increases Tautness between ratchet parent 4 and plunger tube 1.

Ejector pin 8 passes axially through static iron core 3, and is formed with fit-up gap 10 between ejector pin 8 and static iron core 3.When dynamic ferrum Core 2 towards when moving in static iron core 3 direction, slowly discharge through fit-up gap 10, right with this by the air between dynamic iron core 2 and static iron core 3 2 certain cushioning effects of dynamic iron core, it is to avoid press and cause because of quick washing between wheel 5 and runner 6 to damage, extend and use the longevity Life.

The above is only better embodiment of the present utility model, therefore described in all patent claims according to this utility model Construction, the equivalence changes done of feature and principle or modification, be all included in this utility model patent claim.
