The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, a door apparatus 10 according to an embodiment includes a door 14, a door edge 13, and a door locking device, where the door 14 is perpendicular to the door edge 13 when the door 14 is closed, and the door locking device is configured to lock the door 14 to the door edge 13.

The door 14 may be a door, a drawer door, or a cabinet door.

The door lock device comprises a door lock assembly 12 and a door catch assembly 11, wherein the door lock assembly 12 is fixed on a door body 14, and the door catch assembly 11 is fixed on a door edge 13.

The door lock assembly 12 is a conventional one, the door lock assembly 12 is fixed to an inner side of the door body 14, and the door lock assembly 12 has a retractable latch bolt 121.

Alternatively, the door lock assembly 12 may be a fingerprint lock, or a conventional mechanical lock.

The door latch assembly 11 is fixed to the inner side of the door frame 13, and the door latch assembly 11 includes a housing 111, an automatic door pushing unit 112, and a rolling shaft 113. The housing 111 is provided with a limiting portion 1111, the automatic door pushing unit 112 includes a door pushing member 1121 and an elastic member 1122, the door pushing member 1121 is movably disposed on the housing 111, the elastic member 1122 is disposed on the housing 111 and is in transmission fit with the door pushing member 1121, and the rolling shaft 113 is rotatably disposed on the limiting portion 1111.

The limiting portion 1111 is disposed opposite to the door body 14 in the closed door state, the door pushing piece 1121 abuts against the door body 14 in the closed door state, and the elastic piece 1122 is used for enabling the door pushing piece 1121 to have potential energy for pushing the door body 14 in the closed door state; the latch bolt 121 of the door lock assembly 12 can be retracted by being pressed by the side wall of the rolling shaft 113 in the door closing process of the door body 14, and after the latch bolt 121 moves to the side of the rolling shaft 113 far away from the door body 14 in the door closing state, the latch bolt 121 is ejected and limited by the limiting portion 1111.

When the door 10 is used, when the door is to be locked, that is, when the door 14 is switched from the door-open state to the door-closed state, the free end of the door 14 gradually rotates toward the door edge 13, after the latch 121 of the door lock assembly 12 on the door 14 contacts the rolling shaft 113 of the door catch assembly 11 on the door edge 13, the latch 121 retracts under the acting force of the rolling shaft 113 along with the continuous rotation of the door 14, and when the door 14 rotates to the door-closed state, the latch 121 moves to the side of the rolling shaft 113 away from the door 14, and the latch 121 loses the acting force from the rolling shaft 113, and at this time, the latch 121 automatically pops out and is limited by the limiting portion 1111. In the process of switching the door body 14 from the door opening state to the door closing state, because the bolt 121 is retracted under the action of the rolling shaft 113, the bolt 121 drives the rolling shaft 113 to rotate when moving in the process of contacting the rolling shaft 113, and the rolling shaft 113 can effectively prevent the occurrence of the situation that the door latch assembly 11 is jammed or the bolt 121 is jammed, so that the reliability is high. When the door is to be opened, that is, in the process of switching the door body 14 from the closed state to the open state, after the latch bolt 121 is operated and separated from the door catch assembly 11, the elastic member 1122 applies an acting force to the door pushing member 1121, so that the door pushing member 1121 automatically pushes the door open, thereby implementing automatic opening of the door, and the door opening process is very convenient.

Referring to fig. 1 and 2, in one embodiment, the rolling shaft 113 is located on a side of the limiting portion 1111 away from the door edge 13 under the condition that the door latch assembly 11 is fixed to the door edge 13.
