The utility model content

The purpose of the utility model is at this a kind of mechanical double code lock pin to be provided, and complicacy, security performance are not very high deficiencies to overcome the existing password lock construction.

The utility model is to realize like this; Construct a kind of mechanical double code lock pin; It is characterized in that: comprise lock head component, lock tail assembly and a plurality of digit wheels between lock head component and lock tail assembly, wherein in lock head component, digit wheel and lock tail assembly, inner prop is set

Locking bar is set in the inner prop, has locking bolt on the locking bar, said inner prop have with locking bar on the corresponding locking bar control flume of locking bolt,

Be provided with the tapered end lock core assembly that constitutes by tapered end lock core pole and tapered end spring in the said lock head component,

Be provided with the lock tail lock core assembly that constitutes by lock tail lock core pole and lock tail spring in the said lock tail assembly,

Be provided with digit wheel control spring, digit wheel control steel ball in each digit wheel,

Be provided with the digit wheel lock core assembly that constitutes by digit wheel lock core pole and digit wheel spring in each digit wheel,

Wherein be provided with lock core control steel ball at two digit wheel lock core inter-modules near lock tail assembly.

According to the described a kind of mechanical double code lock pin of the utility model, it is characterized in that: said digit wheel is 4 or 6.

According to the described a kind of mechanical double code lock pin of the utility model, it is characterized in that: lock head component is provided with the location screw mandrel.

The advantage of the utility model is: the described a kind of mechanical double code lock pin of the utility model is through improving; Overcome the defective that the existing password lock construction is complicated, security performance is not high; It is easy to operate easily, security performance and theftproof performance are higher, is convenient to promote.
