The upper rail 4 and the lower rail 5 are detachably set between the two vertical rods 2, and the middle part of the U-shaped base rod 1 is detachably set.

[0026] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The U-shaped base rod 1 includes a left L-shaped rod 11, a right L-shaped rod 12, and a connecting sleeve 13. The right end of the left L-shaped rod 11 is connected to the connecting sleeve 13, and the left end of the right L-shaped rod 12 is detachably connected to the connecting sleeve 13. Specifically, the left end of the right L-shaped rod 12 is provided with a first V-shaped spring piece 14, which has a first locking post. The connecting sleeve 13 is provided with a first locking hole 15, and the first locking post of the first V-shaped spring piece 14 extends out of the left end of the right L-shaped rod 12 and locks into the first locking hole 15. The left L-shaped rod 11 is connected to the connecting sleeve 13 by rivets or screws. Of course, the connection method between the left L-shaped rod 11 and the connecting sleeve 13 can also be the same as the connection method between the right L-shaped rod 12 and the connecting sleeve 13. When the locking pin of the first V-shaped spring 14 is pressed, the first locking pin of the first V-shaped spring 14 disengages from the first locking hole 15.

[0032] Reference Figure 1 , Figures 4 to 7 The top outer periphery of the stepped portion 86 is provided with an upper locking portion 862, and the top of the upper lug 84 is provided with an upper locking slot 842. The upper locking portion 862 is locked in the upper locking slot 842. The second hinge shaft 87 can be a rivet, and the top of the second hinge shaft 87 can press against the top surface of the stepped portion 86. The cooperation between the upper locking portion 862 and the upper locking slot 842 makes the stepped portion 86 and the upper lug 84 relatively fixed. The outer periphery of the column 35 is provided with two lower locking portions 352, and the inner sidewall of the column hole 331 is provided with two lower locking slots 332. Each lower locking portion 352 corresponds to one lower locking slot 332 and is located in the lower locking slot 332. The cooperation between the lower locking portion 352 and the lower locking slot 332 makes the column 35 only able to move up and down relative to the column hole 331, but not rotate.

[0033] Reference Figure 1 , Figures 4 to 7 When an external force is applied to the C-shaped rod 3 to make it rotate, the upper hinge 31 and the step portion 86 rotate together. When the step portion 86 rotates, the column 35 can move up and down under the cooperation of the upper tooth portion 861 and the lower tooth portion 351 and the action of the second spring 36. Under the cooperation of the upper tooth portion 861 and the lower tooth portion 351, the step portion 86 has a stop when rotating, so that the C-shaped rod 3 also has a stop when rotating.

[0034] Reference Figure 1 , Figure 4 and Figure 6Both ends of the upper rod 4 are provided with second V-shaped spring pieces 41, each with a second locking post. The upper rod sleeve 83 has a second locking hole 831, and the second locking post of the second V-shaped spring piece 41 extends out of the upper rod 4 and engages in the second locking hole 831. Both ends of the lower rod 5 are provided with third V-shaped spring pieces 51, each with a third locking post. The lower rod sleeve 93 has a third locking hole 931, and the third locking post of the third V-shaped spring piece 51 extends out of the lower rod 5 and engages in the third locking hole 931. When the second locking post of the second V-shaped spring piece 41 at both ends of the upper rod 4 is pressed, the second locking post of the second V-shaped spring piece 41 disengages from the second locking hole 831, at which point the upper rod 4 can be removed. When the third locking post of the third V-shaped spring piece 51 at both ends of the lower rod 5 is pressed, the third locking post of the third V-shaped spring piece 51 disengages from the third locking hole 931, at which point the lower rod 5 can be removed.

[0035] Reference Figures 1 to 7 The design principle of this utility model is as follows: When the bed rail is needed, the two vertical bars 2 are unfolded relative to the U-shaped base bar 1, and the two C-shaped bars 3 are unfolded relative to their corresponding vertical bars 2. When the bed rail needs to be taken out or packed away, the upper and lower rails 4 and 5 are first removed, and then the middle part of the U-shaped base bar 1 is disassembled, separating the left L-shaped bar 11 and the right L-shaped bar 12. Finally, the two C-shaped bars 3 are folded relative to their corresponding vertical bars 2, and the two vertical bars are folded relative to the left L-shaped bar 11 and the right L-shaped bar 12 respectively. This greatly reduces the space occupied and packaging volume of the bed rail, making it easier to carry. When the bed rail needs to be used again, the U-shaped base bar 1, upper rail 4, and lower rail 5 can be reassembled.

[0036] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
