As shown in fig. 1 to 9, the embodiment provides a drawer assembly, which can be applied to storage equipment such as a disinfection cabinet and a kitchen floor cabinet, and can improve the stability of the drawer in the drawing process and improve the use experience of a user. The drawer assembly comprises a drawer frame 1 and a linkage mechanism 2.

Referring to fig. 1 and 2, the drawer frame 1 is disposed in the liner 200 of the machine body 100 in a first direction in a drawable manner. The link mechanism 2 comprises a first link 21, a second link 22 and a third link 23, one end of the first link 21 is rotatably connected to the drawer frame 1, the other end is rotatably connected to the second link 22, one end of the second link 22 is rotatably connected to the inner wall of the liner 200, the other end is rotatably connected to one end of the third link 23, one end of the third link 23 far away from the second link 22 is rotatably connected to the drawer frame 1 and is slidable relative to the drawer frame 1 along a second direction, and the second direction is perpendicular to the first direction. In this embodiment, the first direction is the depth direction of the liner 200, and the second direction is the width direction of the liner 200.

According to the drawer assembly provided by the embodiment, when the drawer frame 1 is pulled or pushed by the connecting rod mechanism 2, the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 are rotated in pairs, because the rotating connection position of the first connecting rod 21 and the drawer frame 1 is fixed, the rotating connection position of the second connecting rod 22 and the inner wall of the liner 200 is fixed, and the third connecting rod 23 can only slide along the second direction relative to the drawer frame 1, in the process of pulling the drawer frame 1, the relative rotating movement of the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 can only be converted into the telescopic linear movement along the first direction, so that the drawer frame 1 can only move in the first direction, the left and right shaking of the drawer in the pulling or pushing process is prevented, the stability of the drawer pulling is effectively improved, and the experience of a user in using storage equipment is improved.

Optionally, referring to fig. 3 and 4, linkage 2 further includes a fixing rail 24 extending in the second direction, fixing rail 24 is mounted to drawer frame 1, first link 21 is rotatably connected to fixing rail 24, and third link 23 is slidably rotatably connected to fixing rail 24. The fixing rail 24 provides a rotational connection basis for the first link 21 and the third link 23, and simultaneously enables the rotational points of the first link 21 and the third link 23 to be positioned on the same line, thereby ensuring rotational synchronicity of the first link 21 and the third link 23, converting the rotational movement of the link mechanism 2 into a linear movement along the first direction, and improving the movement stability of the drawer frame 1.

In this embodiment, the first connecting rod 21, the second connecting rod 22, the third connecting rod 23 and the fixing crosspiece 24 are fixed by pin riveting, that is, hinged between each other, so as to realize rotational connection between each other, and enable the connecting rod mechanism 2 to flexibly stretch out and draw back.
