The expansion box 104 has a second opening that is communicated with the first opening; the door panel 105 assembly includes a door panel 105, and the door panel 105 is detachably covered on the second opening. When the door panel 105 is opened relative to the second opening, at least part of the expansion box 104 can slide out of the cabinet body 1 along the sliding cavity 103.

[0045] On the basis of the above embodiment, an improvement can be made. The sliding cavity 103 has an adjustment groove 101. Along the width direction of the cabinet body 1, the adjustment groove 101 is provided on the outer wall of the sliding cavity 103 away from the receiving cavity, and the adjustment groove 101 extends along the thickness direction of the cabinet body 1; a fixing hole is provided on the side wall of the expansion box 104, and the fixing hole is correspondingly arranged with the adjustment groove 101. The expansion box 104 is relatively fixed to the cabinet body 1 through a limiting connecting piece 102 that sequentially passes through the adjustment groove 101 and the fixing hole; when the limiting connecting piece 102 is disassembled, the expansion box 104 can slide relative to the sliding cavity 103.

[0046] Exemplarily, the fixing hole is a threaded hole, and the limiting connecting piece 102 is a screw or a bolt, which enhances the connection stability of the expansion box 104 on the sliding cavity 103.

[0047] In some embodiments, two sets of adjustment grooves 101 are provided. Along the width direction of the cabinet body 1, the two sets of adjustment grooves 101 are respectively provided on the side walls of the sliding cavity 103 opposite to the two sides of the first opening, so as to perform bilateral limiting on the expansion box 104, and its connection stability with the cabinet body 1 is relatively high.

[0048] In more embodiments, each set of adjustment grooves 101 is provided with two, that is, the expansion box is limited along both sides of the width direction of the cabinet body 1 and along both sides of the height direction of the cabinet body 1 at the same time, further improving the stability maintenance of the expanded space after the expansion box 104 extends out of the sliding cavity 103 of the cabinet body 1.

[0049] As an example, the door panel 105 is hinged to the expansion box 104, and the door panel 105 opens and closes the second opening by rotating relative to the expansion box 104. Specifically, the door panel 105 is hinge-connected to the side wall of the expansion box 104 close to the second opening. Further, a handle 106 is fixed on the outer wall of the door panel 105, and the handle 106 is located on the side of the door panel 105 facing away from the expansion box 104.

The bearing assembly includes a placement plate 107, and the placement plate 107 is fixedly connected to the inner wall of the receiving cavity. The placement plate 107 is used to bear the items placed in the receiving cavity.

[0051] Further, a plurality of placement plates 107 are provided. Along the height direction of the cabinet body 1, the plurality of placement plates 107 are arranged at intervals in the accommodation cavity of the cabinet body 1. For example, three placement plates 107 are provided, and the three placement plates 107 are fixed at equal intervals on the inner wall of the accommodation cavity.

[0052] In other embodiments, the bearing assembly further includes a moving plate 2. The placement plate 107 is provided with a moving groove, which is opened on the side wall of the placement plate 107 facing the door panel 105. The notch direction of the moving groove is the same as that of the first opening. The moving plate 2 is arranged in the moving groove and can move relative to the moving groove and extend out of the moving groove. In this way, when the moving plate 2 is pulled out, the bearing area of the placement plate 107 can be expanded to cooperate with the extension box 104 to extend out of the cabinet body 1 to expand the storage space of the accommodation cavity.

[0053] As a possible embodiment, the bearing assembly further includes a rotating assembly. The moving plate 2 is movably connected to the moving groove through the rotating assembly. The rotating assembly includes a connecting rod 201 and a rotating wheel 202. The connecting rod 201 is connected between the moving plate 2 and the rotating wheel 202. The rotating wheel 202 is rotatably connected to one end of the connecting rod 201 away from the moving plate 2, so that when the rotating wheel 202 rotates and moves along the moving groove, it will drive the moving plate 2 to extend out of the moving groove.

[0054] Further, along the plate length direction of the placement plate 107, the moving groove includes a connected stretching cavity 108, a moving cavity 109, and a rotating cavity 110, which are respectively arranged corresponding to the moving plate 2, the connecting rod 201, and the rotating wheel 202; along the thickness direction of the placement plate 107, the cavity sizes of the stretching cavity 108, the moving cavity 109, and the rotating cavity 110 are respectively adapted to the moving plate 2, the connecting rod 201, and the rotating wheel 202. Through the design of the moving groove with three sections of cavities, the moving plate 2, the connecting rod 201, and the rotating wheel 202 can slide relative to the moving groove better.

[0055] Based on the above embodiments, an improvement can be made. The assembly includes a fixed block 203, a moving pull plate 204, and a limiting sleeve rod 205. The fixed block 203 is fixedly connected to the placement plate 107. The moving pull plate 204 is fixedly connected to the moving plate 2. The limiting sleeve rod 205 includes a fixed rod 207 and a moving sleeve. The fixed rod 207 is fixedly connected to the fixed block 203. The moving sleeve has a limiting cavity 206. The moving sleeve is sleeved on the outer periphery of the fixed rod 207 through the limiting cavity 206 and can axially move relative to the fixed rod 207. The moving sleeve is fixedly connected to the moving pull plate 204.

[0056] The fixed rod 207 has a first limiting protrusion 208, which is located at one end of the fixed rod 207 close to the moving pull plate 204 and is arranged along the circumferential direction of the fixed rod 207; the inner wall of the moving sleeve along its circumferential direction is provided with a second limiting protrusion 209; when the moving pull plate 204 drives the moving sleeve to move relative to the fixed rod 207 towards the door panel 105, the second limiting protrusion 209 is used to abut against the first limiting protrusion 208 to limit the moving distance of the moving sleeve.

[0057] In more examples, a limiting piece 210 is further provided on the circumferential outer wall of the fixed rod 207 on the side close to the first limiting protrusion 208. The side of the limiting piece 210 facing the fixed block 203 is an arc surface, so as to reduce the contact stress with the second limiting protrusion 209 and extend the service life of the component.

[0058] Next, the working state of an embodiment of the present application will be described:

[0059] When the filing cabinet of the present application is in use, personnel can directly pull the handle 106 to rotate the door panel 105 to open the expansion box 104, so that materials can be placed into the accommodating cavity of the cabinet body 1; and the limiting connecting piece 102 can also be rotated and removed, and then the expansion box 104 is pulled and pulled out relative to the cabinet body 1 to a certain position, and then the limiting connecting piece 102 can be fixed to the adjusting groove 101 and the fixing hole; then the moving pull plate 204 is pulled to move the moving plate 2. When the moving plate 2 is moved, it will drive the connecting rod 201 to make the rotating wheel 202 rotate in the rotating cavity 110. At the same time, when the moving pull plate 204 is pulled, it will drive the sliding sleeve of the limiting sleeve rod 205 to move. After moving a certain distance, it is limited. That is, when the moving plate 2 is pulled out too much, the limiting piece 210 will abut against the second limiting protrusion 209 to prevent the moving plate 2 from detaching from the placing plate 107.
