The key lock structure includes a casing, a sliding base disposed in the casing, an orientation frame arranged on a bottom face of the sliding base and a plurality of code-locked keystroke bodies. The sliding base has a plurality of elongation arms parallel to one another, a plurality of slots arranged with the elongation arms in an alternate manner, and a plurality of stop portions disposed in the respective slots. The orientation frame is disposed under the sliding base. Each of the code-locked keystroke bodies has a sliding member, which has an extrusion portion capable of being blocked by the respective stop portion. Consequently, the ode-locked keystroke bodies are fixed and cannot be pressed in the lock status. | 01-15-2009 |
| 20150368929 | PRY-PROOF APPARATUS OF COMBINATION LOCK - The invention relates to a pry-proof apparatus of combination locks, including a lock case, a lock bottom that can be pivoted on or fixed to the lock case, where the lock case are provided with plural apertures on it and a lock base fixed firmly to the lock bottom. And the lock base includes a housing seat, a movable member, plural number discs, plural shaft members, and a fastening device and a pry-proof apparatus. By means of pry-proof fingers for shielding the shaft member that makes the probing tool to pry for nothing, which substantially avoids pries and prying tools. Therefore, this apparatus features locking function of original combination locks, simplicity of structure and assembly, and pry-proof, which accomplishes the objective of this creation. | 12-24-2015 |
| 20150376915 | PRY-PROOF APPARATUS OF COMBINATION LOCK - The invention relates to a pry-proof apparatus of combination locks, including a lock case, a lock bottom, a housing seat, a movable member, plural number discs, plural shaft members, and a fastening device which base on the structure of the shaft member. Once a pry inserts a tapering plate probing tool into the aperture again, the probing tool can only be descended to the outer peripheral portion of the shaft member, where the probing tool pries for nothing. | 12-31-2015 |
