Abstract

A tool cabinet includes a cabinet body having two guide rails and a routing space that is proximate to one of the guide rails, a working platform unit having a protective tube, two lifting units, a driving unit, and a power supply unit having a transmission wire. The working platform unit includes two extension members respectively slidable relative to the guide rails. Each lifting units includes a threaded rod extending through a respective extension member. The driving unit is disposed for driving rotation of the threaded rod of a respective one of the lifting units. The transmission wire has an end connected to the driving unit, and an opposite end extending through the protective tube into the routing space.

Dependent claims

A tool cabinet comprising:

a cabinet body including
a top wall that is formed with a guide hole, and
two spaced-apart guide rails respectively disposed proximate to opposite ends of said top wall and extending in a vertical direction, said cabinet body defining a routing space that is proximate to one of said guide rails, and that is in communication with said guide hole;
a plurality of drawers movably disposed in said cabinet body, and disposed under said top wall;
a working platform unit including
a platform member that is disposed above said top wall,
two hollow extension members that are respectively disposed on opposite ends of said platform member, and that are connected respectively to said guide rails, each of said extension members being slidable relative to a respective one of said guide rails, and
a protective tube that extends downwardly from said platform member in the vertical direction through said guide hole, and that has a bottom end portion, said working platform unit being movable relative to said cabinet body between a lowered position, where said platform member is proximate to said top wall and where said bottom end portion of said protective tube is distal from said top wall, and a lifted position, where said platform member is distal from said top wall and where said bottom end portion of said protective tube is proximate to said top wall;
two lifting units, each of which includes
a guide tube that is disposed on said cabinet body and that extends in a respective one of said guide rails,
a nut that is disposed fixedly on a top end of said guide tube, and
a threaded rod that is connected rotatably to said working platform unit, that extends through a respective one of said extension members, and that is threadedly connected to said nut;
a driving unit disposed on said working platform unit for driving rotation of said threaded rod of a respective one of said lifting units relative to said nut of the respective one of said lifting units, thereby driving the movement of said working platform unit between the lowered and lifted positions;
and
a power supply unit including
a power supply module that is disposed on said cabinet body, and
a transmission wire that has an end electrically connected to said driving unit, and an opposite end extending through said protective tube into said routing space and electrically connected to said power supply module.
