Preferably, the roller assembly 630 includes two pairs of wheels symmetrical about the lifting lug 620, and each pair of wheels includes a roller 632 connected to two ends of the connecting shaft 631, so that the lifting lug 630 always moves in the vertical direction through two pairs of four rollers.

When the bed fence is disassembled, the positioning pin 650 needs to be pulled down, the cover 640 needs to be removed, the first button 140 needs to be pressed down, an upward acting force is applied to the lifting lug 620 or the cross bar 200, the roller rolls on the vertical pipe 300 and can be taken out, and then any side of the bed fence can be taken out upwards, so that the bed fence is simple and convenient to assemble and disassemble.

The button type unlocking structure is simple in structure, the cross rod and the vertical rod are connected, the height of the fence is adjusted through the button, the installation and the disassembly of the cross rod can be controlled through the other button, and the connection strength of the whole structure is high; utilize button unlocking structure to build the rail, it is convenient to splice, and the horizontal pole steadiness of rail is high in the use, and the control range height of rail can satisfy user's demand, can also adapt to the height of mattress, and the suitability is high.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
