Solution to lock core, overall plan still adopts coded lock, but it is inner owing to the loading elastic force causes can sending the slight sound or shakes this deficiency when the password runner rotates to correct position to have improved it, any device that can produce elastic force is not set in the inside of this product, like this in the process of password runner rotation, even a certain password runner rotates to correct position, can not send any special sound or vibrations yet, do not know that for those people of password wants to unblank, can only take the method for attempting successively, increase the group number of password so again by the number of teeth that increases the password runner, thereby increase the safety of lock.

Advantage of the present utility model and good effect:

1, because internal construction simple, so the bulk strength of internal firmware can both increase accordingly.

2, cancelled the device that can produce elastic force that conventional combination lock had, thereby avoided when the password runner rotates to correct position, sending the sound or shaken this fatal deficiency.

3, need not use key can open this lock, avoid in the past because of losing the worry that key brings.

4, remedy the deficiency of material with rational profile, thereby utilize less material just can make integral body reach very high intensity, balance the contradiction between material price, the intensity.

5, in the process of producing, the number that increases the password runner just can increase the group number of password, thereby can increase the degree of safety of lock greatly.

6, the profile of each part all is consistent, need not to have the parts of special processing.
