Self-adaptive expandable linkage locking device

Abstract

The invention provides a self-adaptive expandable linkage locking device. In the device, a lock body is arranged on the contact faces of a pair of storing and transporting boxes, a driving shaft extends out between the contact faces, and the lock body comprises a shell, a moving cam, two driven components and a driving threaded pair; the moving cam is arranged in the shell; the driving screw of the threaded pair is supported by two baffle plates, a floating nut matched with the driving screw is placed in a square hole in a moving cam, and the moving cam can move in the inner cavity of the shell and along the x-axis of the shell under the drive of the driving threaded pair; the moving cam is provided with chutes which are symmetric about the driving screw up and down; the sliding pin of the two driven components run through the chutes which are symmetric up and down and guide sleeves on the shell; the locking pins of the driven components are arranged in the guide holes of pin seats, one end of each locking pin is connected with a connecting piece, and the two locking pin seats are fixed in upper and down two sub-boxes; one end of the long round hole of each connecting piece is mounted in the empty groove of the moving cam and at a position corresponding to a chute; and the sliding pins run through the long round holes and the chutes at the same time and the two ends of each sliding pin are inserted into the guide grooves of the shell.

Description

technical field [0001] The invention relates to an adaptive and expandable linkage locking device, which is used for locking objects in the box when multiple boxes or other similar boxes are assembled together. Background technique [0002] The multi-package box is composed of sub-boxes arranged in multiple rows and columns. Each sub-box has the same or symmetrical structure, can carry a large load, and the objects loaded in it are the same. During the storage and transportation of multi-package boxes, due to the multi-layer stacking, the exposed operable surface of the box is less, and the ordinary locking device does not meet the requirements for locking and unlocking the items in each sub-box, so only the operating space can be used. A small interlock locking device is required. Since the multi-package is assembled by separate processing and multi-package, there is an assembly error during the assembly process, which makes the relative position deviation between the item...

Problems solved by technology

[0003] At present, the common linkage locks are often multi-point linkage locks with a single lock body, which are used for multi-point linkage locking of a single object, such as various anti-theft doors, cabinets, etc., which are light door locks and do not have multi-lock multi-point linkage. functions, and does not have the ability to expand, and cannot meet the requirements for the use of multi-packages
