Definitions

  • the present invention relates to a mechanical locking mechanism, especially a mutual-constraint safety multi-drawer locking mechanism with a function of locking all-drawer each time, however, during using, only one drawer can be opened each time.
  • the multi-drawer locking mechanism only has the function of locking all-drawer and unlocking all-drawer simultaneously.
  • all the other drawers shall be in the unlocked openable state, causing mutual interference and making several drawers simultaneously slide out.
  • the operator must be careful, otherwise it is easier to cause several other drawers to slide out simultaneously.
  • the toolbox shall lose its gravity center, causing collapse, and the tools spilling on the ground or safety accidents happening. So the existing multi-drawer locking mechanism is unreasonable, it is necessary to improve it.
  • the purpose of present invention is to provide a mutual-constraint safety multi-drawer locking mechanism with the function of locking all-drawer, but during using, only one drawer can be opened each time, and that only after the opened drawer closed and reset, another drawer can be selected to open.
  • the main body of this mutual-constraint safety multi-drawer locking mechanism consists of a mounting bracket, a driving mechanism and an action actuating mechanism. It is characterized in that the mounting bracket is formed by a main bottom plate, an upper top plate, a lower bottom plate, a limit cover plate and a curved baffle plate.
