Abstract

A link lock of display shelf comprises a lock shell, locking plate and eccentric wheel. The eccentric wheel comprises wheel shaft, eccentric plate and wheel hat. The eccentric plate is installed on the shaft, and the wheel hat is fixed on the eccentric plate. The locking plate is fixed in the lock shell, to the head of the locking plate installs two knuckles, to the tail part the locking plate opened a hole correspondingly link to the eccentric plate. The knuckles protrude from the closed shell. A wheel shaft hole is opened to the end of the closed shell. A groove is opened on the wall of the closed shell for eccentric wheel installation. An inner parts installation window is opened to the tail of the closed shell. This link lock is characterized of higher strength, better reliability, simple die set and increase the strength of extruded display shelf.

Description

technical field [0001] The invention relates to a connection lock for exhibition appliances, in particular to a connection lock for high-strength exhibition rack components. Background technique [0002] The existing lock housing is provided with multiple windows and bosses at the end of the lock housing in order to obtain the required shape to achieve locking, prevent the eccentric wheel from moving down, and prevent the eccentric from collapsing. Such as: setting holes for the curved part of the tail of the reed, setting side holes for letting the eccentric cam have a certain anti-collapse eccentric effect, setting bosses to prevent the reed from moving down and collapsing eccentrically, and setting up two more processes for process needs hole. Since many holes are opened on the lock case, the strength of the lock case is greatly reduced, and the lock case is cracked when the locking torque is too large, and it is not very effective in preventing the eccentricity from col...
