  • the locking element 325 may be a structure provided with limiting posts 326 and limiting grooves 327 cooperating with each other.
  • the limiting posts 326 extend from front ends disposed at two sides of the sealed barrel 310 toward the panel of the drawable box 320; and the limiting grooves 327 are formed on two sides of the panel of the drawable box 320 and configured to cooperate with the limiting posts 326 to lock the position of the drawable box 320.
  • Each of the limiting grooves 327 includes a horizontal section toward the sealed barrel 310, where the horizontal sections are for the limiting posts 326 to enter in a pulling direction of the drawable box 320; each of the limiting grooves 327 is provided with an accommodating groove in the tail end along a height direction; and each of the limiting posts 326 enters the corresponding accommodating groove along the height direction after reaching the tail end of the corresponding horizontal section, thus realizing locking.
  • the drawable box 320 is pulled out, a user lifts the pivoting handle 321, the limiting posts 326 are released from the accommodating grooves and can be released from the accommodating grooves along the pulling direction of the drawable box 320.
  • the sealed drawer 300 is sealed by extrusion of a sealing element (such as a silicone rubber sealing gasket), and can be conveniently sealed and unlocked by using the pivoting handle 321 based on structural improvement. This facilitates operation of users.
