The specific embodiment
Like Fig. 3 and shown in Figure 4, the shock-absorbing of the utility model machinery magnetic force lock comprise the iron plate 211 that is positioned at a side and from the iron plate 211 vertical protrusion pulling plug 212 and be positioned at opposite side magnet 221, be positioned at magnet 221 and open top can be inserted the sleeve 222 of pulling plug 212 and is nested with the locating snap ring 223 in this sleeve 222 peripheries.Wherein, the termination of pulling plug 212 forms flange.The mechanism in the aperture that having on sleeve 222 and the locating snap ring 223 works in coordination regulates these sleeve 222 internal cavities; This mechanism comprises a plurality of circular holes that have on sleeve 222 sidewalls on the one hand; The ball of in each circular hole, placing 224; Side wall inner surfaces at locating snap ring 223 forms step on the other hand, and the aperture, top of the internal cavities of locating snap ring 223 is bigger than lower part aperture.Locating snap ring 223 is fixed on the magnet 221, and sleeve 222 bottoms can be installed on the substrate 226 of magnet 221 belows by relative substrate 226 through bottom linker 227 rotationally, and magnet 221 can move axially with respect to sleeve 222 with locating snap ring 223.Be provided with spring 229 between sleeve 222 and the locating snap ring 223.
Bottom linker 227 1 ends are fixed on sleeve 222 bottoms; The other end is fixed on the cushion block 225 below the substrate 226; The corresponding opening that sleeve 222 bottoms are passed on the substrate 226 is resisted against on the cushion block 125, and on the substrate 226 diameter of corresponding opening greater than sleeve 222 base diameters and less than the maximum gauge of cushion block 125 horizontal sections.Wherein, bottom linker 227 is preferably screw, and the cushion block 225 that on the screw rod between the nut of sleeve 222 bottoms and screw, is nested with is preferably the iron block that upper and lower surfaces is an arc.
Preferably, the sleeve 222 upper opening edges formation flange that extends radially outwardly, more preferably the diameter of the flange of sleeve 222 opening parts is greater than the outer diameter of locating snap ring 223.
As an example, substrate 226 can be made up of the aluminium groove.A plurality of circular holes on sleeve 222 sidewalls can be six, and ball 224 can be six steel balls.
The shock-absorbing of the utility model machinery magnetic force lock is the adhesive of adopting electromagnetism and the mode of release realizes the process of unblanking to lock, and the conversion of electromagnetic force and mechanical force is to spur the displacement of lock body inner part through the electromagnetism adhesive to realize mutual conversion.
After the lock body energising; The iron plate 211 of the magnetic field adhesive opposite side of magnet 221 generations at closing time; Pulling plug 212 inserts from the open top of magnet 221 middle sleeves 222 simultaneously; As shown in Figure 3, at this moment the large aperture part of locating snap ring 223 is surrounded the ball 224 on the sleeve 222, and the termination flange of pulling plug 212 slips over ball 224 and gets into sleeve 222 inner chambers.At this moment be to keep by the magnetic adhesion of magnet 221 and iron plate 211 to lock, do not have mechanical force, the coupling mechanism force of this moment is less.
When iron plate 211 receives external force; Because the suction-combining force effect between iron plate 211 and the magnet 221, iron plate 211 drives magnet 221 and leaves substrate 226, and is as shown in Figure 4; Thereby the elastic force that makes locating snap ring 223 overcome spring 229 moves up with respect to sleeve 222; Surround the ball on the sleeve 222 up to the small-bore of locating snap ring 223 part, a plurality of balls on the sleeve 222 along radially to the center extruding, are held the termination flange of the pulling plug 212 that inserts tightly under the effect of locating snap ring 223; Produce self-locking and convert mechanical pulling force into, realize big pulling force locking state.The suction-combining force of existing magnet 221 has the mechanical force of locking ball 224 again, thereby reaches the purpose of locking at this moment, has the bigger power of locking.
When lock body cut off the power supply, the magnetic field of magnet 221 disappeared, and locating snap ring 223 resets under the elastic force effect of spring 229, and drive magnet 221 is shifted to substrate 226 and is resisted against again on the substrate 226, and at this moment the large aperture part of locating snap ring 223 is surrounded the ball on the sleeve 222.When the pretension on acting on iron plate 211 (precompression) was lower than requiring of regulation, the termination flange of pulling plug 212 was extracted out from sleeve 222, and iron plate 211 is separated with magnet 221, realizes unblanking.Because the restoring force of spring 229 is certain, spring force is not enough to locating snap ring 223 is resetted when pretension (precompression) is too big, and pulling plug 212 just can not be extracted out and die and can not unblank, and can unblank when being lower than setting so have only when pretension (precompression).
