[0046] See also Figures 1 to 17 The self-closing fence door shown in the figure includes a door body, which may be one or more door bodies. The door body has two opposite ends, and the fence door has a working state. In the working state, the two ends of the door body are left and right ends. One end of the door body is rotatably connected to the door post, and the other end of the door body is connected to the door post or another door body through a locking assembly, that is, one door body is provided at one door opening, or two door bodies are provided at one door opening.

[0047] The locking assembly includes a first locking member and a second locking member. The first locking member is arranged on a door column or another door body, and the second locking member is arranged on the door body. The first locking member includes a first locking plate 4 and a second locking plate 5. The front end of the first locking plate 4 is provided with a first opening groove 411 opening forward, that is, the opening of the first opening groove 411 passes through the front end of the first locking plate 4.

[0048] The front end of the second locking plate 5 has an inclined surface 52 inclined toward the rear side (the front end refers to the side where the operator stands in front of the door body, and the rear end refers to the side behind the door body). The second locking plate 5 is closer to the second locking member than the first locking plate 4. The second locking plate 5 is rotatably connected to the first locking plate 4. The lower end of the second locking plate 5 is provided with a second opening groove 51 opening downward, that is, the opening of the second opening groove 51 passes through the lower end of the second locking plate 5; the second locking member includes a locking rod 8, and the locking rod 8 is horizontally arranged.

[0049] The first locking plate 4 and the second locking plate 5 are provided with corresponding holes, and the first locking member, the door body and the second locking member can be locked by installing a mechanical lock in the hole. When the door body is to be opened, the mechanical lock is opened to push the door body to rotate outward.

[0050] The first locking member has an initial state. When in the initial state, the first opening groove 411 is opposite to the second opening groove 51 and forms a closed hole, that is, an annular hole, having a circle.

[0051] The fence gate has a closed state and an open state. When in the closed state, the first opening groove 411 and the second opening groove 51 are opposite to each other and form a space for locking the locking rod 8. The locking rod 8 is partially located in this space. At this time, the rotation of the door body can be restricted, and then a mechanical lock is installed to lock the door body and the door post; when in the open state, the first opening groove 411 and the second opening groove 51 are opposite to each other to form a locking space, but the locking rod 8 is not in the locking space, the locking rod 8 is disengaged from the first opening groove 411 and the second opening groove 51, and the door body rotates away from the second locking member.

[0052] When a door body rotates, the locking rod 8 pushes the inclined surface 52 of the second locking plate 5 so that one end of the second locking plate 5 with the inclined surface 52 moves upward, and the other end of the second locking plate 5 moves downward, so that the first opening slot 411 is exposed, and the locking rod 8 extends into the first opening slot 411, and the door body can be self-locking; when the door body is opened, the front side of the second locking plate 5 is held to move one end of the second locking plate 5 with the inclined surface 52 upward, so that the first opening slot 411 is exposed, and the locking rod 8 exits the space along the first opening slot 411. When a door body rotates toward another door body or door column, the locking of one door body and another door body or door column can be achieved to prevent the door body from opening, and unlocking is also simple and convenient, achieving self-locking; the appearance of the fence frame is coordinated and consistent, and the structure is simple.
