Description
Technical field
The utility model relates to the safeties of mechanical-electrical fuze, is specifically related to a kind of electromagnetic locking mechanism.
Background technology
For the insurance of fuse, what at present application was more is generally that motor drives, but motor drives the defects such as to have volume large, expensive, limits its use on fuse.
Also have a kind of insurance institution often used in fuse to be exactly gunpowder promotional implement, this mechanism is the device of the high temperature and high pressure gas promotion piston acting utilizing electric energy to excite gunpowder and produce.This device generally have structure simple, export that energy is large, function reliability advantages of higher, but its arming action is dull, generally only does axial push-and-pull campaign.And this mechanism exists and once does work, can not Reusability, act on the shortcomings such as unreliable after longer-term storage.
Another applies the recoverable dynamo-electric safeties of more insurance function is exactly marmem promotional implement, and memorial alloy promotional implement is the memory effect utilizing marmem, realizes the functions such as retardation time of fuse insures, mechanism can detect, can recover.Marmem has the advantages such as volume is little, lightweight, nonmagnetic, driving force is large, but also there is many defects in memorial alloy driveability, mainly response speed slow (actuation time is at more than 2S), response frequency are low, and excitation consumed energy is large, add that the application of reason marmem in engineering such as on the high side is also subject to many restrictions.
Utility model content
The utility model provides a kind of electromagnetic locking mechanism, is renewable type insurance institution, solves existing fuze safety mechanism low-response, energy consumption is large, cost is high problem.
The technical solution of the utility model is: comprise electromagnet, safety plug, baffle ring, dead ring, touch ring, insulation sleeve, switch body, fixture block, spring leaf and wire, described electromagnet bottom is provided with tapped hollow guiding post, described safety plug upper end is provided with external screw thread, with hollow guiding post inner hole, described switch body is connected with electromagnet lower surface, which is provided with longitudinal hole, hollow guiding post is located in switch body longitudinal hole, described safety plug outer wall sheathed described baffle ring successively from top to bottom, dead ring and insulation sleeve, described tactile ring set is located at insulation sleeve outer wall, described switch body sidewall is provided with cross through hole, two described fixture blocks are provided with in cross through hole, described fixture block is installed with described spring leaf near longitudinal hole side, described spring leaf can with tactile ring, dead ring and insulation sleeve wall contacts, have at least a spring leaf to be connected with described wire.
Preferred as such scheme, described fixture block is positioned at the both sides of longitudinal hole in cross through hole, is fixed in described cross through hole by dog screw.
Preferred as such scheme, described insulation sleeve lateral wall is ledge structure, and its lateral wall upper diameter is less than lower diameter, and described tactile ring set is located at the top of insulation sleeve, touches ring external diameter identical with insulation sleeve lower outer diameter.
The beneficial effects of the utility model are: the structure of said mechanism is simple, and security is high, and action response time is short, and reliability is high, and production cost is low, and the solution that can detect fuse fast protects situation.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is in safety position.
Fig. 2 is that the utility model is in the structural representation separating guarantor's state.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the present embodiment comprises electromagnet 1, safety plug 2, baffle ring 3, dead ring 4, touch ring 5, insulation sleeve 6, switch body 9, fixture block 10, spring leaf 13 and the wire be connected with spring leaf 13, electromagnet 1 bottom is provided with tapped hollow guiding post 8, safety plug 2 upper end is provided with external screw thread, with hollow guiding post 8 inner hole, switch body 9 is connected with electromagnet 1 lower surface, which is provided with longitudinal hole 7, hollow guiding post 8 is located in the longitudinal hole 7 of switch body 9, safety plug 2 outer wall sheathed baffle ring 3 successively from top to bottom, dead ring 4 and insulation sleeve 6, touch ring 5 and be sheathed on insulation sleeve 6 outer wall, switch body 9 sidewall is provided with cross through hole 12, is provided with two fixture blocks 10 in cross through hole 12, and fixture block 10 is installed with spring leaf 13 near longitudinal hole 7 side, spring leaf 13 can with tactile ring 5, dead ring 4 and insulation sleeve 6 wall contacts.
In the present embodiment, fixture block 10 is positioned at the both sides of longitudinal hole 7 in cross through hole 12, is fixed in cross through hole 12 by dog screw 11.
In the present embodiment, insulation sleeve 6 lateral wall is ledge structure, and its lateral wall upper diameter is less than lower diameter, and tactile ring set is located at the top of insulation sleeve, touches ring 5 external diameter identical with insulation sleeve 6 lower outer diameter.
During assembling, first insulation sleeve and safety plug are located, again tactile ring set is entered the outer step of insulation sleeve, make the lower end cylindrical of insulation sleeve concordant with tactile ring cylindrical, then dead ring and baffle ring are inserted in safety plug respectively, keep coaxial with safety plug, the safety plug then have insulation sleeve by overlapping, touching ring, dead ring and baffle ring is screwed in the hollow guiding post of electromagnet.Fixture block put into the cross through hole of switch body and locate with dog screw, the side near longitudinal hole on fixture block is located at by spring leaf, because spring leaf has certain elasticity, tightly can be clipped in fixture block both sides to fix, spring leaf both sides have circular aperture and are used for welding lead, pour into appropriate WD1001 high-performance acrylic acid fat sqtructural adhesive at wire root after having welded, and make glue cover wire, but do not allow the endoporus and the outer round surface that flow to switch body.This operation in order to solder joint insulation, strengthens again the position of spring leaf on the one hand on the one hand.Finally by circular hole in electromagnet component entirety insertion switch body.During concrete operations, loaded in fuze mechanism by electromagnetic locking mechanism parts complete for assembling, now, electromagnetic locking mechanism is in home position.When powering to electromagnetic locking mechanism forward, the safety plug of electromagnetic locking mechanism gos deep in electromagnet, and spring leaf contacts with insulation sleeve, detects that the lead-in wire be connected with spring leaf is off state, and now the flame proof parts of fuse are in separate and protect position, as shown in Figure 2; When oppositely powering to electromagnetic locking mechanism, the safety plug of electromagnetic locking mechanism stretches out electromagnet, spring leaf and tactile loop contacts, now safety plug lower end relocks fuse flame proof parts, the wire conducting be connected with spring leaf now detected, fuse is in safety position, as shown in Figure 1.
