[
detailed description of the invention]
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment one:
Theftproof lock as shown in Fig. 1 to 7, it comprises: a kind of theftproof lock, comprise spring 31, spring bolt 32, lock body 1, lock core 2, lock pin 3, key 4, described lock body 1 has lock pin groove 11 and lock core groove 12, described lock pin 3 is arranged in described lock pin groove 11, described lock pin 3 quantity is three to four ten, preferably, the quantity of lock pin is two, four, six, eight, ten, 12, described lock pin spring and spring bolt are enclosed in lock pin groove, described lock pin 3 is provided with gear recesses, the height of gear recesses on lock pin is identical or different, described lock core 2 is arranged in described lock core groove 12, described lock core 2 is provided with lock core gear 21, the number of teeth of described lock core gear 21 is identical with the quantity of lock pin, described lock core gear is rotated by described lock core 2 and agrees with mutually with the gear recesses that arranges on described lock pin or stagger, the secret coefficient of lock can be improved, improve the theftproof performance of locking device.
