A security anti-theft locking device

Abstract

A safety and anti-theft lock control device, comprising: a lock body box, a half-type side shaft, a passive stress gear, a force-bearing toggle pin, and a locking stress shaft piece, which is characterized in that the bottom of the lock body box is fixed by a half-type side shaft, and On the half-type side shaft, there is a shaft center hole of the passive stress gear to be dynamically assembled with it, and the passive stress gear is fixed with a load-bearing toggle pin; the locking stress shaft piece is set and operated in the groove of the lock body box, and There is a transverse stress slot on the part suitable for the bearing toggle pin to move. Since the transverse stress slot passes through the extension hole left on the side of the axis line of the passive stress gear, it can be used for the bearing toggle pin to move along with it. The passive stress gear rotates at least 180 degrees, and the margin of the transverse slot on the other side passes through the axis line of the passive stress gear to a dead angle within 15 degrees. When the locking stress shaft is moved in the groove by bearing force When the pin is moved here, it is just blocked by the dead angle, which means that a kind of lock control stress check and balance relationship is satisfied.

Description

technical field [0001] The invention relates to a safe and anti-theft lock control device in which lock control and lock force are generated by passing through a shaft center limit point. Background technique [0002] At present, although there are many types of locking and locking products such as fireproof and anti-theft door locks, safe locks, and car control locks, in the design of the main control function, they have always used and relied on additional springs or extension springs to form the "resistance" of the mechanism. Limiting device" to achieve the satisfaction of the locking function. However, due to the lack of the principle of mechanical checks and balances, this traditional structure is easy to be pried once it is damaged by an external force due to insufficient spring adhesion, resulting in the loss of the lock control support force and the lock security state. Therefore, the long-term perplexity of this problem exists, restrains and affects the security im...

However, due to the lack of the principle of mechanical checks and balances, this traditional structure is easy to be pried once it is damaged by an external force due to insufficient spring adhesion, resulting in the loss of lock control support and lock security state.

Therefore, the long-term perplexity of this problem exists, constrains and affects the security improvement of lock technology always.
