[specific embodiment]
As shown in the figure, theftproof lock comprises lock box 11, key 12 and lock core 13, and active card is equipped with dead bolt 21 and card article 31 in the lock box 11, and dead bolt 21 is provided with the boss 210 and first projection 211, and key 12 promotes dead bolt 21 by first projection 211 and slides; Card article 31 is provided with the fixture block 310 and second projection 311, and fixture block 310 can lean in boss 210 1 sides and slide with restriction dead bolt 21, and key 12 promotes to move on the card article 31 by second projection 311; First spring 22 of outside roof pressure dead bolt 21 and second spring 32 that downward roof pressure card article 31 resets are housed in the lock box 11.
Wherein, dead bolt 21 horizontal positioned, first projection 211 is upwards prolonged vertical pieces for set in the middle of the dead bolt 21, and dead bolt 21 1 ends are provided with two parallel projection 212, two projections 212 correspondences and are inserted in the two set draw-in grooves 113 of lock box 11; Dead bolt 21 other ends are provided with horizontal sliding bar 213, the first springs 22 and are sleeved on the horizontal sliding bar 213, and hole clipping 114 backs that horizontal sliding bar 213 front ends pass on the lock box 11 link to each other with one handle 19.
The lock core 13 outer positioning sleeves 15 that also are provided with, among the present invention, lock core 13 is installed in the positioning sleeve 15 rotationally, and lock core 13 outsides also have annular groove 133, positioning sleeve 15 is provided with the alignment pin 16 that stretches in the cover, and alignment pin 16 salient mountings also can slide by relative annular groove 133 in annular groove 133.
The using method of key 12 and theftproof lock is as follows:
The first step: as shown in Figure 2, adjust lock core 13, make bar-shaped trough 131 on the lock core 13 face gathering sill 151 on the positioning sleeve 15, this moment, bar-shaped trough 131, gathering sill 151 formed the jack that can confession key 12 enters together;
Second step: as shown in Figure 6 and Figure 7, key 12 is inserted, after key 12 inserts, the inclined-plane 121 of key 12 front ends leans at second protruding 311 downsides, along with the preceding in-migration of key 12 promotes to move on second projection 311, card article 31 compressions this moment second spring 32, the fixture block 310 on the last card article 31 moves on to step 210 tops, and dead bolt 21 breaks away from the restriction of card article 31.
