Double-channel luggage central control lock

Abstract

The invention provides a double-channel luggage central control lock which comprises a lock shell, a central control lock set, a custom lock set, a side lock and a linkage mechanism. When the central control lock set and the custom lock set are locked at the same time, unlocking of the edge lock is limited through the linkage mechanism, and the limitation on the edge lock is released through the linkage mechanism when the central control lock set and the custom lock set are unlocked. The linkage mechanism comprises a left connecting head, a right connecting head, left and right transmission connecting rods, left and right limiting blocks and a locking rod. The locking rod is matched with the central control lock set and moves left and right along with unlocking and locking of the central control lock set. The left connecting head and the right connecting head are connected with the two ends of the locking rod correspondingly. The left connecting head is matched with the custom lock set and moves left and right along with unlocking and locking of the custom lock set. The two ends of the transmission connecting rod are hinged to the corresponding connecting heads and the corresponding limiting blocks correspondingly. The limiting blocks can be rotationally connected to the lock shell through a fixing shaft. Limiting heads are arranged on the limiting blocks. When the central control lock is locked, the limiting heads abut against the edge lock. The double-channel luggage central control lock has the beneficial effects that the structure is simple, and transmission is reliable.

Description

technical field [0001] The invention relates to a centrally controlled lock for double-channel luggage.

[0002] The dual-channel luggage central lock generally adopts a combination lock or other key lock used by consumers and a customs lock to open the central lock group respectively, thereby releasing the restriction on the side lock. For the reliability of the lock, the more complicated it is The lower the structural reliability, the greater the probability of failure, and the more difficult the production and installation will be. The structures of the two sets of lock groups in the existing dual-channel luggage central control lock are more complicated, especially when driving the side lock to open. In the transmission mechanism of locking and locking, more parts are often required to complete the more complicated transmission. No matter which part is jammed or damaged, the entire lock body will be unusable, so there are defects of low reliability and complicated installation. Most of the existing dual-channel luggage central control locks use long strips to directly contact the side locks to realize the restriction on the side locks. However, due to the long distance between the central control locks and side locks of luggage, this The structure of direct horizontal abutment restriction has the defect of deformation and dislocation failure of the long strip transmission strip, and also has the unreliability of being easily pushed away by force, and this long strip transmission strip requires a larger abutment surface and abutment strength , often requires a larger width and thickness, and takes up more space, which brings a greater problem to the central control panel of the luggage with insufficient space.
