The plug connector 3 is arranged on the back of the back plate of the drawer 2; the head of the plug 3 gradually expands from back to front to the left and the right to form a triangle. The side surface of the connector 3 has a limit groove 31 for limiting the roller 42 of the action arm 4 in a first state described below.

The action arms 4 are arranged on the front surface 111 of the cavity wall behind the accommodating cavity 11 of the shell 1, and the action arms 4 are distributed at intervals, wherein the two action arms 4 can move relative to the shell 1 and can enable the two action arms 4 to approach or move away from each other. The end of the activation arm 4 has a roller 42. The action arms 4 are movable relative to the housing 1 in particular in such a way that each action arm 4 is arranged in a rotatable manner on a front surface 111 of the chamber wall behind the receiving chamber 11 of the housing 1. The mounting block 6 is disposed between a front surface 111 of a rear chamber wall of the housing chamber 11 of the housing 1 and the corresponding action arms 4, each action arm 4 having a rotation shaft 41 extending in the up-down direction, the rotation shaft 41 being rotatably disposed on the mounting block 6. The spring element 5 acts on the movable actuating arm 4 with a tendency to move the two actuating arms 4 towards each other. In this embodiment, the elastic member 5 is a torsion spring, the middle portion of the torsion spring is sleeved on the rotating shaft 41, and two ends of the torsion spring respectively abut against the mounting block 6 and the corresponding acting arm 4. In other embodiments, more than two action arms 4 may be provided, for example, 3 or 4, only one of the action arms 4 may be capable of rotating relative to the housing 1, and the elastic member 5 may also be an elastic sheet.

During the extension of the drawer 2, the plug connector 3 has two states with respect to the two actuating arms 4: referring to fig. 3, in the first state, the plug 3 is inserted backwards between the two action arms 4 and abuts against the two action arms 4; in a second state, see fig. 4, the plug 3 is moved forward out of engagement with the two actuating arms 4.

The utility model also provides a disinfection cabinet, which is applied with the drawer cabinet structure as above, as shown in fig. 1 and fig. 2, i.e. the shell 1 is the cabinet body of the disinfection cabinet.

The working principle and the using method of the drawer cabinet structure of the embodiment are as follows.

When the drawer 2 is closed, the drawer 2 is pushed inwards, the plug connector 3 is inserted between the two action arms 4 until the roller 42 is limited in the limiting groove 31 (figure 3) of the plug connector 3, so that the closing speed of the drawer 2 is favorably reduced, the drawer 2 cannot violently collide with the front surface of the cavity wall behind the accommodating cavity of the shell 1, and the noise generated when the drawer 2 is closed is reduced; in addition, the idler wheel 42 is limited in the limiting groove 31 of the plug-in connector 3, the acting force between the idler wheel and the plug-in connector 3 is large, the plug-in connector 3 is not easy to be separated forwards, and the drawer 2 is not easy to rebound.

When the drawer 2 is opened outwards, the plug 3 moves forward and disengages from the two actuating arms 4, and the two actuating arms 4 return to a position in which they are close to each other under the action of the elastic element 5 (fig. 4).

Example 2:

as shown in fig. 6 to 10, the structure is substantially the same as that of embodiment 1, except that: both action arms 4 are slidably disposed in the left-right direction on the front surface 111 of the chamber wall behind the housing chamber 11 of the housing 1. The buffer mechanism comprises an action block 7 arranged between a front surface 111 of the cavity wall behind the accommodating cavity 11 of the shell 1 and the corresponding action arm 4; of the action block 7 and the action arm 4, the action arm 4 has a slide groove 43 extending in the left-right direction and opening toward the action block 7, and the action block 7 has a stopper portion 71 extending in the up-down direction into the slide groove 43. The elastic part 5 is a tension spring, one end of which is pressed against the corresponding action arm 4, and the other end is pressed against the other action arms 4 or the action block 7. In other embodiments, the positions of the sliding slot 43 and the position-limiting portion 71 can be interchanged, only 1 action arm 4 can be arranged on the front surface 111 of the cavity wall behind the accommodating cavity 11 of the housing 1 in a manner of sliding in the left-right direction, and the elastic element 5 can also adopt other structures, such as a reed.

The working principle and the using method of the drawer cabinet structure of the embodiment are as follows.

Similarly, when the drawer 2 is closed, the drawer 2 is pushed inwards, the plug connector 3 is inserted between the two action arms 4 until the roller 42 is limited in the limiting groove 31 (fig. 7) of the plug connector 3, and meanwhile, the two action arms 4 slide towards two sides, so that the closing speed of the drawer 2 is favorably reduced, the drawer 2 cannot violently collide with the front surface of the cavity wall behind the accommodating cavity 11 of the shell 1, and the noise generated when the drawer 2 is closed is reduced; in addition, the idler wheel 42 is limited in the limiting groove 31 of the plug-in connector 3, the acting force between the idler wheel and the plug-in connector 3 is large, the plug-in connector 3 is not easy to be separated forwards, and the drawer 2 is not easy to rebound.

When the drawer 2 is opened outwards, the plug 3 moves forward and disengages from the two actuating arms 4, while the two actuating arms 4 slide towards the middle under the action of the elastic element 5 until they return to the condition of mutual approach (fig. 8).
