Anti-fall components 40 are installed on the two first support members 11 at corresponding positions of at least one shelf area 30.
[0030] refer to Figures 1 to 3 The anti-fall component 40 includes a limiting elongated hole 411 and a locking area 421 fixed or formed at the same height on the two first support members 11, and a blocking member 43. The limiting elongated hole 411 is arranged through in the left-right direction and has a first length in the vertical direction. The lower side of the limiting elongated hole 411 corresponds to the position of the shelf 3 (at the same height). The upper side of the locking area 421 has a locking opening 422 and the locking area 421 has a second length in the vertical direction. The blocking member 43... The width of 3 corresponds to the width of the two first support members 11, and the lower end of the blocking member 43 is rotatably installed in the limiting elongated hole 411 and can slide up and down along the limiting elongated hole 411. A locking part 420 is formed on the upper or middle end of the blocking member 43, which can enter or exit the locking area 421 from the locking port 422 and can move up and down within the locking area 421. The lower side of the locking part 420 has a clearance area greater than the second length, and the first length is greater than the second length. In this embodiment, the locking port 422 is located on the upper side of the locking area 421 and opens upwards. Alternatively, the locking port 422 can also be located on the front side of the locking area 421 and open forwards. The size of the locking part 420 is smaller than the size of the locking port 422, allowing it to enter and exit relative to the locking port 422.
[0031] refer to Figure 4The lower end of the blocking piece 43 has a sliding part 410 installed in the limiting long hole 411 and can slide up and down and rotate freely in the limiting long hole 411. The upper end or middle end of the blocking piece 43 is formed with an engaging part 420 which can enter or disengage the engaging area 421 from the engaging hole 422 and can move up and down in the engaging area. The length of the engaging area 421 in the up and down direction is less than the first length.
