In this embodiment, the third mark indicates that the fourth expansion member 14 is not inserted into the fourth socket 321, and the fourth mark indicates that the fourth expansion member 14 has been inserted into the fourth socket 321, ensuring that the door railing body 1 is assembled with the second lower seat 32.

    [0032] Specifically, a second support rod 51 is provided, and the two ends of the second support rod 51 are respectively connected with the second upper seat 31 and the second lower seat 32, the second support rod 51 is movably provided with a second moving seat 52, and the side of the second moving seat 52 away from the second door body is provided with a second plug board (not shown in the figure) that can be inserted into or withdrawn from the second moving seat 52, the second plug board is fixed in the installation position, and the second support rod 51 can be fixed in the installation position through the connection between the second moving seat 52 and the second plug board, suitable for the installation position with a skirting line.

    [0033] Specifically, the second upper seat 31 is detachably fixed in the installation position through the second quick release mechanism, and reference can also be made to prior art for the second quick release mechanism, which will not be further elaborated here.

    [0034] Specifically, the door body is an integrated structure, or the door railing body 1 includes a first door body and a second door body, the top and bottom of the first door body, as well as the top and bottom of the second door body, are fixedly connected to a first bar member 15 and a second bar member 16, respectively, the two ends of the first bar member 15 are bent and extended to cover partial back wall of the first door body and partial front wall of the second door body, and the two ends of the second bar member 16 are bent and extended to respectively cover partial back wall of the first door body and partial front wall of the second door body, and the second door body can, relative to the first door body, move between the position where the first strip members (15) are in contact with each other and the position where the first strip members (15) are away from each other, and the two bent and extending ends of the first strip member 15 and of the second strip member 16 can prevent the disconnection between the first and second door bodies; [0035] one side of the first door body is detachably and pivotally connected to the first connecting mechanism 2, and the side of the second door railing away from the first door body is detachably and pivotally connected to the second connecting mechanism 3, and the connection between the first door body and the first connecting mechanism 2 can be disconnected, and the door railing can swing and slide to restore the access, with the connection position between the second door body and the second connecting mechanism 3 as the rotation center; the connection between the second door body and the second connecting mechanism 3 can also be disconnected, and the door railing can swing and slide to restore the access, with the connection position between the first door body and the first connecting mechanism 2 as the rotation center.

    [0036] Specifically, the first and second door bodies are integrated structures or foldable structures, and reference can also be made to prior art for the first quick release mechanism, which will not be further elaborated here.

    [0037] Specifically, the bottom of the first door body and/or second door body is provided with one or more universal balls (not shown in the figure) for rolling contact with the ground.

    [0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any equivalent structural transformation made based on the description and accompanying drawings hereof under the concept of present invention, or be directly/indirectly applied in other related technical fields, should fall within scope of patent protection of the present invention.
