The top of each lifting rod 40 is connected to the horizontal guardrail 20. The bottom of each lifting rod 40 is coaxially movably placed in the fixed rod sleeve 30. The part of any lifting rod 40 located in the fixed rod sleeve 30 is provided with a locking structure, and the fixed rod sleeve 30 cooperating with the lifting rod 40 is provided with an unlocking structure. The unlocking structure cooperates with the locking structure to lock or unlock the lifting rod 40.

[0035] In an embodiment of the present invention, there are three perforations, and correspondingly there are three fixing rod sleeves 30 and lifting rods 40. The spacing between adjacent fixing rod sleeves 30 is 60cm-70cm, and the length of the horizontal guardrail 20 is consistent with the length of the bed.

[0036] In an embodiment of the present invention, the lifting rod 40 is connected to the horizontal guardrail 20 by a connecting piece, a screw and a screw seat combination. The upper end surface of the fixed rod sleeve 30 is provided with a connecting seat, which is fixed to the side bed rail 10 by screws.

[0037] In an embodiment of the present invention, an expanded diameter end cap 41 is fixed to the bottom end of each lifting rod 40, and an auxiliary spring 31 is installed at the bottom of the fixed rod sleeve 30. The bottom end of the auxiliary spring 31 is fixed to the bottom end of the fixed rod sleeve 30, and the top end of the auxiliary spring 31 is pushed against the expanded diameter end cap 41. When the locking structure is in the unlocked state, the auxiliary spring 31 can push the lifting rod 40 to a preset height, making the operation more convenient and efficient.

[0038] In an embodiment of the present invention, the locking structure includes a conical spring 51 and a locking rod 52. A mounting slot 42 is vertically defined on the outer wall of the lifting rod 40. The bottom of the locking rod 52 is hinged to the bottom of the mounting slot 42. The conical spring 51 is fixed to the top sidewall of the mounting slot 42. One side of the top of the locking rod 52 is fixed to the telescopic end of the conical spring 51. A locking protrusion 521 is fixed to the other side of the top of the locking rod 52. The sidewall of the fixed rod sleeve 30 is defined by an upper locking hole 301 and a lower locking hole 302 that cooperate with the locking protrusion 521. When the locking protrusion 521 is engaged in the upper locking hole 301, the horizontal guardrail 20 is located above the bed. When the locking protrusion 521 is engaged in the lower locking hole 302, the horizontal guardrail 20 is located below the bed surface. It should be noted that the rotation trajectory of the locking rod 52 is arc-shaped, the head end of the locking protrusion 521 is arc-shaped, and the upper locking hole 301 and the lower locking hole 302 are arranged corresponding to the locking protrusion 521.
