Description

technical field [0001] The invention relates to the field of fixed connection devices, in particular to a connection lock. Background technique [0002] The LED display screen is spliced ​​by multiple LED cabinets. Due to the heavy weight of the LED cabinets, connection locks are usually used to splice multiple LED cabinets together. [0003] At present, the splicing between the LED cabinets is generally connected and locked by a locking device with high strength. The locking device on the market generally includes a metal fixing piece and screws, and the two ends of the metal piece are respectively fixed by screws. Two adjacent LED boxes, so as to achieve the purpose of fixed connection. However, this connection method of the LED box is time-consuming and laborious in the actual operation process, and the efficiency is low. [0004] The application number is 201410155096.9, and the Chinese patent titled the lock mechanism discloses a lock used for connecting the display b...
