Under the effect of inner spring 903, interior one deck pellet shot from a slingshot 902 has an end to be positioned at blind hole 104, the other end is positioned at one deck pellet shot from a slingshot through hole 201, because interior one deck pellet shot from a slingshot 902 is across lock core cover 1 and lock core supplementary cap 2, lock core supplementary cap 2 at this moment can not overlap 1 with respect to lock core and rotate;
In the present embodiment, lock core 3 has anti-rotation pin-and-hole 303, the anti-rotation pin-and-hole 202 that lock core supplementary cap 2 has, lock core cover 1 has the excessive hole 103 of stop pin, the excessive hole 103 of stop pin that stop pin 7 passes lock core cover 1 is inserted in the anti-rotation pin-and-hole 303 of the anti-rotation pin-and-hole 202 of lock core supplementary cap 2 and lock core 3, and lock core 3 and lock core supplementary cap 2 are fixed together;
The middle part of lock core 3 is provided with shift fork mouth 307 corresponding to driving mouth 203 places of lock core supplementary cap 2, and the rear end of lock core 3 is provided with plectrum socket 306 and rivet hole 304;
The middle part of ∏ shape shift fork 4 has rivet hole 403, two arms of ∏ shape shift fork 4 have outside angled end-face 401, ∏ shape shift fork 4 is snapped in the plectrum socket 306 of lock core 3, two arms of ∏ shape shift fork 4 from the key groove hole 301 of lock core 3 stretch into make outside angled end-face 401 arrive shift fork mouths 307, pass the rivet hole 403 of ∏ shape shift fork 4 and the rivet hole 304 of lock core 3 with rivet 22, ∏ shape shift fork 4 is fastenedly connected in lock core 3;
A kind of folding key (Fig. 1-Fig. 3), comprise key body 12, spring 10, card pearl 15, key card 13 and rivet 14 that the present invention proposes;
One end of key card 13 has arc gap 1301, the other end has the pearl face 1304 of pressure and angled end-face 1303, nearly arc gap 1301 places have rivet hole 1302, spring 10 and card pearl 15 are packed in the spring eye 1203 of key body 12, the card slot 1201 that two key cards 13 oppositely are stacked together and put into key 12, card pearl 15 pressing springs 10 and with the arc gap 1301 of key card 13 (see figure 3) that connects, rivet 14 penetrates the rivet hole 1302 of the rivet hole 1202 of key body 12 and key card 13 and carries out riveted and fixed, key card 13 can rotate in card slot 1201 around rivet 14, and spring 10 compresses key card 13 by card pearl 15.
The procedure declaration of unblanking of the present invention (seeing Fig. 8, Fig. 9 and Figure 10):
Folding key is pushed in the key groove hole 301 of lane change lock core (as Fig. 8);
Folding key is in the process that pushes the lane change lock core, the angled end-face 1303 of key card 13 touches the shift fork end inclined-plane 401 of shift fork 4,2 key cards 13 begin respectively around rivet 14 to both sides rotation (see figure 9), folding key continues to push, key card 13 constantly is rotated in place to the shift fork mouth 307 of lock core 3 and stretches out, at last, the microcephaly that the pressure pearl face 1304 of key card 13 presses interior two layers of pellet shot from a slingshot 901 makes to push and puts in place, card pearl 15 snaps in the side of key card 13, make interior two layers of pellet shot from a slingshot 901 and interior one deck pellet shot from a slingshot 902 respectively in the blind hole 104 to interior one deck pellet shot from a slingshot through hole 201 of being sitting at lock core supplementary cap 2 and lock core cover 1, simultaneously, the key tooth hole 1204 of key 12 also puts microcephaly's extrusion of one deck pellet shot from a slingshot 9 in place, make one deck pellet shot from a slingshot 9 and two layers of pellet shot from a slingshot 8 respectively in the lock tube pellet shot from a slingshot hole 102 to the lock core marble hole 302 that is sitting at lock core 3 and lock core cover 1, at this moment can overlap 1 screw key body 12 with respect to lock core, drive lock core 3 simultaneously, lock core supplementary cap 2, shift fork 4 and the plectrum 6 of unblanking rotate the (see figure 10) of unblanking.
Otherwise, outwards extract in the process of folding key, the pressure pearl face 1304 of key card 13 is got back in the card slot 1201 of key body 12 around rivet 14 rotations under the effect of the circular arc limit of the shift fork mouth 307 of lock core 3 face 308, card pearl 15 snaps in (see figure 9) in the arc groove 1301 of key card 13, at this moment, interior two layers of pellet shot from a slingshot 901 and interior one deck pellet shot from a slingshot 902 return to normality under the effect of inner spring 903 (interior two layers of pellet shot from a slingshot 901 are positioned at one deck pellet shot from a slingshot through hole 201, interior one deck pellet shot from a slingshot 902 has an end to be positioned at blind hole 104, the other end is positioned at one deck pellet shot from a slingshot through hole 201, and lock core supplementary cap 2 at this moment can not overlap 1 with respect to lock core and rotate); Simultaneously, under the effect of spring 10, one deck pellet shot from a slingshot 9 is positioned at 302, two layers of pellet shot from a slingshot 8 of lock core marble hole has an end to be positioned at lock core marble hole 302, and the other end is positioned at lock tube pellet shot from a slingshot hole 102, and lock core 3 at this moment can not overlap 1 with respect to lock core and rotate (as Fig. 4).
Example two
The difference of present embodiment and embodiment one is folding key (as Figure 11, Figure 12 and Figure 13):
Comprise key body 12,2 springs 10,2 card pearls 15,2 key cards 13 and 2 rivets 14;
Proximal end is provided with card slot 1201 in the key body 12, the side of card slot 1201 and the key body 12 formation opening that communicates, the middle part vertically is provided with the spring eye 1203 of the pair of parallel of passing card slot 1201 in the key body 12, one end of spring eye 1203 is positioned at key body 12 middle parts, the other end is positioned at key body 12 ends, and 2 rivet holes 1202 pass key body 12 and communicate with card slot 1201; Key body 12 middle parts have key tooth hole 1204.
For cooperating this folding key, blind hole 104 positions (seeing Figure 15) in the shape (seeing Figure 16) of the ∏ shape shift fork 4 in the lane change lock core, the lock core cover 1, and lock core supplementary cap 2 in interior one deck pellet shot from a slingshot through hole 201 and to drive mouthful 203 positions (seeing Figure 14) also slightly different.
