And the drawings described are only schematic and are non-limiting.

In this context, for the sake of brevity, not all possible combinations of individual features in the various embodiments or examples are described. Therefore, the respective features in the respective embodiments or examples may be arbitrarily combined as long as there is no contradiction between the combinations of the features, and all the possible combinations should be considered as the scope of the present specification.

The contents appearing in the present invention, which do not belong to the protection object of the present invention, are all for making the technical personnel in the field understand the present solution more easily, and should not be understood as seeking protection to these contents, and these contents all belong to the prior art.

In the description of the embodiments of the present invention, it should be further noted that unless otherwise explicitly stated or limited, the terms "disposed," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be connected in wired or wireless communication; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other; one or more of the above meanings may be referred to. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Fig. 1 shows a schematic structural diagram according to an embodiment of the present invention. As shown in fig. 1, the bed fence opening and closing alarm device comprises a first fixing device 1, an alarm device 2, a trigger fixing piece 3, a trigger moving piece 4 and a second fixing device 5; the first fixing device 1 is used for arranging the alarm device 2 and the trigger fixing piece 3 at a bed fence fixing part 6; the second fixing device 5 is used for arranging the trigger movable piece 4 at a movable part 7 of the bed fence; when the trigger movable part 4 approaches or contacts the trigger fixed part 3, the trigger fixed part 3 enables the alarm device 2 to stop alarming; when the trigger movable part 4 is far away from or separated from the trigger fixed part 3, the trigger fixed part 3 enables the alarm device 2 to alarm.

According to this embodiment, when the bed rail is pulled open or closed, the bed rail fixing part 6 does not move, so that the first fixing device 1 fixed thereon is kept stable, and the bed rail moving part 7 rotates around the bed rail fixing part 6 to drive the second fixing device 5 thereon to rotate. When the bed fence is closed, the trigger movable part 4 is in contact with or close enough to the trigger fixed part 3, the trigger fixed part 3 enables the alarm device 2 to stop giving an alarm, and the contact can be contact without interaction force or pressing with enough acting force. When the bed fence is opened, the trigger movable part 4 is separated from the trigger fixed part 3 or far enough away from the trigger fixed part 3, and the trigger fixed part 3 enables the alarm device 2 to give an alarm.
