DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0017] like Figure 1 , 2As shown, a pull-out cold storage shelf comprises a plurality of shelf units, each of which comprises two rows of three side frame rods 1, three cross bars 3 are evenly connected between adjacent side frame rods 1 from top to bottom, both ends of the cross bars 3 are connected to the side frame rods 1 through cross bar fixing members 4, a pallet guide rail 5 is connected between each column of side frame rods 1 near the bottom of the cross bar 3, a pallet 2 is slidably connected between each pair of pallet guide rails 5, the bottom end of the side frame rod 1 is fixedly connected to the bottom plate of the cold storage through a bottom fixing mechanism 6, the top end of the side frame rod 1 is fixedly connected to the top plate of the cold storage through a top fixing mechanism, and the middle upper and middle lower parts of the side frame rod 1 close to the inner wall of the cold storage are fixedly connected to the inner wall of the cold storage through a back fixing mechanism.

[0018] According to the above structure, tray rails 5 are used on both sides of the shelf. When the tray 2 stores items, if the storage is compact and inconvenient to take out, the tray 2 can be easily slid out through the tray rails 5, which makes it convenient to take out items and can effectively prevent fragile items from colliding and breaking.

[0019] like Figure 3 As shown, the bottom fixing mechanism 6 includes a bottom fixing plate 61, half of which is welded to the bottom end of the side frame rod 1, and the center of the other half of the bottom fixing plate 61 is fixedly connected to the cold storage bottom plate through A cross-slot pan head self-tapping screws 62. This can effectively ensure the bottom is fixed and stable.
