As shown in fig. 2 and 3, the door 12 of the cabinet structure according to the present embodiment cooperates with the door position positioning mechanism 13 to close the storage compartment 111. The door position positioning mechanism 13 includes a position adjuster 132 and a positioning structure such that the position adjuster 132 remains relatively fixed in a predetermined position. Specifically, the door position positioning mechanism 13 further includes an accommodating seat 133, which is composed of an accommodating seat body 1331 and an accommodating seat fixing portion 1332. As shown in fig. 7, the positioning structure includes an elastic protrusion 136 provided in the position adjuster 132, and the receiving seat body 1331 is provided with a first positioning hole 1333 and a second positioning hole 1334, for example, at the second body portion 1336. As shown in fig. 2 and 3, the elastic protrusion 136 is caught in the first positioning hole 1333. At this time, the position regulating member 132 is in the first predetermined position, that is, the position regulating member 132 is completely accommodated in the accommodating space formed by the first body portion 1335 and the second body portion 1336. The door 12 can be completely locked by closing the upper and lower doors 12 and inserting the stoppers 121 of the upper and lower doors into the receptacle body 1331 through the opening 1337 of the first body portion 1335 and the opening 1338 of the second body portion 1336, respectively.

As shown in fig. 4, the door 12 of the cabinet structure according to the present embodiment is fixed in the open position, i.e., the door 12 is opened at a relatively small angle. Fig. 5 and 6 show that the door 12 of the cabinet structure according to the present embodiment cooperates with the door position positioning mechanism 13 so that the door 12 remains fixed in the open position state. Specifically, as shown in fig. 7, the position adjusting member 132 is composed of an opening portion 1321 and a mounting portion 1322. As shown in fig. 5 and 6, first, the stoppers 121 of the upper and lower doors are removed from the opening 1337 of the first body portion 1335 and the opening 1338 of the second body portion 1336, respectively, to open the doors. Then, the position adjuster 132 is rotated 170 degrees out of the receptacle body 1331 (e.g., manually by a user) such that the elastic protrusion 136 snaps into the second positioning hole 1334. At this time, the position adjuster 132 is in the second predetermined position, i.e., the opening portion 1321 of the position adjuster 132 is rotated out of the accommodating seat body 1331 to the outer end thereof. The door 12 can be stably maintained in the open state by inserting the stoppers 121 of the upper and lower doors into the stoppers 132 from the first upper opening 1323 and the second lower opening 1324 of the opening portion 1321, respectively. This can achieve ventilation of the storage chamber 111 to eliminate the odor therein, and also maintain the stability of the door 12 to prevent the door 12 from freely swinging when subjected to an external force.

Further, when the door 12 is switched from the open position state to the position state of closing the opening of the storage compartment, first, the stoppers 121 of the upper and lower doors are removed from the first upper opening 1323 and the second lower opening 1324 of the opening portion 1321, respectively. Then, the position adjuster 132 is rotated back into the receptacle body 1331, at which time the elastic protrusion is switched from being snapped into the second positioning hole 1334 to being snapped into the first positioning hole 1333, i.e. the position adjuster 132 is switched from the second predetermined position to the first predetermined position. The upper and lower doors 12 are closed and the door stoppers 121 of the upper and lower doors are inserted into the receptacle body 1331 from the opening 1337 of the first body portion 1335 and the opening 1338 of the second body portion 1336, respectively, to completely lock the doors again.

Wherein, the diameter of the middle hole of the positioning bead holding part 1363 is smaller than the diameter of the positioning bead 1361, preventing the positioning bead 1361 from being separated from the positioning bead holding part 1363. The positioning bead 1361 has a smaller volume and the whole positioning structure is simpler. When the position adjuster 132 moves from one predetermined position to another predetermined position, the positioning ball 1361 is first pressed by the second body portion 1336 and the compression spring 1362 effects downward movement of the positioning ball 1361 to effect rotation of the elastic projection 136 in the receptacle body 1331; when the positioning ball 1361 rotates to align with the positioning hole, the positioning ball 1361 moves upward under the restoring action of the spring to enter the positioning hole, so as to position the position adjusting member 132. The positioning structure can automatically position the position adjusting piece and is convenient to use. Alternatively, in one implementation of this embodiment, the positioning holes may be provided on the first body portion 1335, and the elastic protrusions 136 may be correspondingly provided at positions to mate with the first body portion 1335. Alternatively, in another embodiment of this embodiment, the positions of the elastic protrusions 136 and the positioning holes may be interchanged.
