Abstract

The invention discloses a high anti-theft level double-lock modularization latch mechanism which comprises a latch cover plate, a lock main plate, a rotating shaft, a transmission mechanism, a longitudinal transmission latch and a transverse transmission latch. The rotating shaft is respectively in linkage connection with the longitudinal transmission latch and the transverse transmission latch through the transmission mechanism. The latch cover plate is connected with the lock main plate through cover plate mounting pillars, and the longitudinal transmission latch and the transverse transmission latch are arranged between the lock main plate and the latch cover plate. The left side and the right side of the lock main plate are respectively provided with a lock body mounting part, and each lock body mounting part is provided with three or more lock body mounting pillars evenly distributed in the circumferential direction in an assembling mode. The longitudinal transmission latch is in locating connection with the lock main plate through the lock body mounting pillars corresponding to any lock body mounting part, and the transverse transmission latch carries out transverse horizontal moving through a guide component arranged on the latch cover plate. Thus, by means of the high anti-theft level double-lock modularization latch mechanism, the diversification of arranging modes of the position of a lock hole relative to the position of a handle can be achieved.

Description

technical field [0001] The invention relates to a high anti-theft grade double-lock modular door bolt mechanism, which belongs to the technical field of safe production. Background technique [0002] In the prior art, the lock installation position and the handle installation position of the commonly used door latch mechanism are fixed. Therefore, the position of the lock hole relative to the position of the handle is fixed and cannot be adjusted arbitrarily. Therefore, when facing abnormal attacks, the anti-theft performance of such safes has defects. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a high anti-theft level double-lock modular latch mechanism, which can realize the diversification of the arrangement of the position of the lock hole relative to the position of the handle, and can To meet the different needs of customers for the position of handles and keyholes in various situations. When the sa...
