The invention relates to a lock structure for a spare wheel up-down regulator. The lock structure comprises a spare wheel supporting frame, a cranking rod and a spare wheel lock. The spare wheel supporting frame comprises an upper support, a lower support, a chain, an upper gear and a lower gear; the upper support is fixed onto a vehicle body; the upper gear is fixed onto the upper support; the lower gear is fixed onto the lower support; the chain is arranged between the upper gear and the lower gear; the inner end of the cranking rod is in rotatable connection with the upper gear; the spare wheel lock is arranged at the outer end of the cranking rod. Owing to the cranking rod, the spare wheel supporting frame and the spare wheel lock, a spare wheel can be lifted up or put down conveniently by cooperation of the cranking rod and the gears on the spare wheel supporting frame; further, by means of structural relation between the cranking rod and the spare wheel lock, utilization of the cranking rod is unaffected when the spare wheel is lifted up or put down at ordinary times; in addition, by adoption of the spare wheel lock, an original locking manner is replaced, and effectiveness in burglary prevention can be achieved.
