[0036] like Figure 7 and Figure 8 As shown, a rotating shaft 7 is provided at the bottom end of the door body 2 close to the rotating box side, specifically, a sealing cap 10 is provided in the lower door beam 22, a fixing hole is provided on the sealing cap 10, a threaded hole is provided axially inside the rotating shaft 7, one end of the rotating shaft 7 extends into the fixing hole and the rotating shaft 7 and the sealing cap 10 are fixed as a whole by screws, and an avoidance groove 97 is provided at the bottom of the lower door beam 22, the sealing cap 10 is inserted into the lower door beam 22, and the sealing cap 10 is fixed to the lower door beam 22 with screws, and an axis hole 131 is provided on the bottom beam 13, the rotating shaft 7 is inserted into the axis hole 131 and rotates in the axis hole 131. Compared with the traditional rotating shaft 7 which is fixed by welding, the rotating shaft 7 of the utility model is detachable, which is convenient for packaging and transportation.

[0037] like Figure 4 , Figure 8 and Fig. 9As shown, a first door lock mechanism 8 is provided between the door body 2 and the door frame 1 on the side away from the rotation connection. The first door lock mechanism 8 includes a first lock box 81 and a second lock box 82. The first lock box 81 is fixed to the end of the upper door beam 21 by screws, and the second lock box 82 is fixed to the left column 11 by screws. The first lock box 81 has a first slide 83, and a lock tongue 84 and a second return spring 85 are slidably provided in the first slide 83. One end of the second return spring 85 abuts against the lock tongue 84, and the other end abuts against the end wall of the slide. The lock tongue 84 is fixedly connected to an unlocking push plate 86 extending out of the first lock box 81. A slide rail 87 is provided on the top of the first lock box 81. The push plate 86 slides on the slide rail 87, and the second lock box 82 is provided with a lock groove 88 for the lock tongue 84 to be inserted into the door body 2 to lock. When the door body 2 is in a locked state and needs to be unlocked, the push plate 86 is driven to slide, thereby driving the lock tongue 84 to slide into the first slide 83 to squeeze the second return spring 85, and the lock tongue 84 retracts and disengages from the lock groove 88 to unlock; when the open door needs to be closed, the push plate 86 is driven to slide, thereby driving the lock tongue 84 to slide into the first slide 83 to squeeze the second return spring 85, and when the lock tongue 84 retracts and corresponds to the lock groove 88, the push plate 86 is released, and under the action of the first return spring 66, the lock tongue 84 extends into the lock groove 88, and the door body 2 is locked.

[0038] like Figure 6As shown, a second door lock mechanism 9 is provided between the door body 2 and the door frame 1 on the side away from the rotation connection. The second door lock mechanism 9 includes a sleeve 91 fixedly connected to the end of the lower door beam 22 and a U-shaped limiting groove 92 fixedly installed on the left column 11. A second slide 93 is provided in the sleeve 91. A limiting column 98 is provided on the innermost side of the second slide 93. A slider 94 and a third return spring 95 are slidably provided in the second slide 93. One end of the third return spring 95 abuts against the slider 94, and the other end is sleeved on the limiting column 98 and abuts against the end wall of the second slide 93. The limiting column 98 is used to prevent the third return spring 95 from losing its position. The two inner side walls of the sleeve 91 have an inwardly buckled elastic hook 96, and the slider 94 has a notch 97 that cooperates with the hook 96 to prevent the slider 94 from slipping off.

When the first door lock mechanism 8 is unlocked, the door lock mechanism is installed slightly. When the second door lock mechanism 9 needs to be closed, the door body 2 on the side where the door lock mechanism is installed is slightly lifted upward, and the slide block 94 slides into the limit groove 92 from top to bottom, and the slide block 94 abuts against the bottom of the limit groove 92 under the action of the third return spring 95. To prevent the slide block 94 of the second door lock mechanism 9 from being stuck when locked, a guide inclined surface is provided on the upper side of the limit groove 92. When the slide block 94 slides from top to bottom, the pressure of the guide inclined surface on the slide block 94 changes from small to large, so that the slide block 94 can slide smoothly into the limit groove 92. To prevent the sleeve 91 from being assembled incorrectly during the assembly process, a protruding rib is provided at the bottom of the outer end of the sleeve 91, and a notch is provided at the bottom of the lower door beam 22 to cooperate with the rib. When the sleeve 91 is installed, the rib of the sleeve 91 corresponds to the notch and slides into the interior of the lower door beam 22.

[0039] In the above scheme, the left column 11, the right column 12, the bottom beam 13 of the door frame 1 and the railing 23 of the door body 2 are all hollow tubes, which can greatly reduce the overall weight of the children's door railing and save transportation costs during transportation.

[0040] When disassembling and installing the door railing, the left and right side connecting pieces 5 in the door frame 1 can be removed to complete the disassembly of the door frame 1. When disassembling the door body 2, the fixing bolts on the upper door beam 21 and the lower door beam 22 can be taken out, and the railing 23 between the upper door beam 21 and the lower door beam 22 can be removed. The upper door beam 21, the lower door beam 22 and the railing 23 of the door body 2 are all disassembled independently. Finally, the left column 11, the right column 12, the bottom beam 13 disassembled from the door frame 1 and the upper door beam 21, the lower door beam 22, and the railing 23 disassembled from the door body 2 are all combined and packaged. By dividing the door frame 1 and the door body 2 into multiple independent modules for disassembly, the packaging size is significantly reduced on the existing basis, thereby further reducing the transportation cost.
