Stress controlled lock in lock

Abstract

This invention relates to stress balance relation lock, which comprises the following parts: lock case, case cover, main control drive structure, stress executive structure, semi-axis, locking stress axis, reset sensor device. The invention is characterized by the following: the stress executive structure an lock stress axis form mechanic stress relationship through main control drive structure main gear and passive gear; the bearing dial bolt lifts or contracts through stress axis, lock bolt; the passive stress gear axis line and lock stress axis vertical middle line are overlapped to generate lock dead angle at 15 degrees.

Description

technical field [0001] The invention relates to a stress compound locking control and locking safety device, in particular to a stress control locking middle lock generated by relying on the limiting force of a mechanical axis. Background technique [0002] At present, there are many types of lock products such as anti-theft door locks, safe locks, and car locks. However, in the technical design of these lock products, most of them add a set of "resistance limiting device" formed by springs (or extension springs) in addition to the main control lock effect function to achieve the satisfaction of the locking function. However, due to the lack of the stress relationship of the mechanical check and balance principle in this traditional technical structure, once it is illegally damaged, the limited support force in the adhesion limit device is difficult to withstand the prying of external force, which will easily lead to the loss of the lock control function. This affects the s...

Problems solved by technology

However, due to the lack of the stress relationship of the mechanical check and balance principle in this traditional technical structure, once it is illegally damaged, the limited support force in the adhesion limit device is difficult to withstand the prying of external force, which will easily lead to the loss of the lock control function. thus affecting the safety state of the locking capability

Therefore, the existence of this problem has always been a difficult problem that restricts the improvement of lockset safety technology for a long time.
