Description

Technical Field

[0001] The utility model relates to a rack with columns having a rotatable baffle tube structure at the upper part. Specifically, it relates to a rack with multiple columns having a rotatable baffle tube structure at the upper part. Background Art

[0002] For traditional racks, their columns are square columns, some of which can be folded and some cannot. Their functions are relatively single. When limiting the front and rear positions of the parts of a rack with rotatable columns, it is necessary to additionally install a baffle rack to achieve this, and the loading and unloading of the baffle rack is very inconvenient. Content of the Utility Model

[0003] The utility model provides a rack with rotatable columns. The rotatable baffle tube structure is located at the upper part of the columns. When needed, the rotating baffle tubes form the front and rear limits of each part, which is convenient.

[0004] The technical solution of the utility model is as follows:

[0005] A rack with rotatable columns, the rack includes a base and four columns. Each column is installed on the base and is a foldable column. A number of parts are placed on the base. When each column is folded, a large picking surface is formed above each part. At least two upper parts of the columns are rotatable baffle tube structures, and the rotatable baffle tube structure includes a baffle tube.

[0006] When each column is unfolded, the baffle tube rotates and is placed in front of and behind each part, forming the front and rear limits of each part.

[0007] The rotation angle of the baffle tube is 90°.

[0008] The column with an upper part being a rotatable baffle tube structure includes an upper and a lower section of the column. A tube Ⅰ is fixedly connected to the lower end of the upper section of the column, and a tube Ⅱ is fixedly connected to the upper end of the lower section of the column. The tube Ⅰ is inserted into or sleeved on the tube Ⅱ and is rotationally and cooperatively connected with the tube Ⅱ. The baffle tube is fixedly connected to the upper section of the column.

[0009] When the baffle tube rotates, the upper section of the column and the tube Ⅰ rotate therewith.

[0010] For the tube Ⅰ and the tube Ⅱ, a limiting rod is provided on one of the tubes and a limiting hole is provided on the other tube. The limiting rod is placed in the limiting hole and cooperates with the limiting hole to form the rotational limit of the baffle tube.

[0011] The column is a square column, and four U-shaped groove frames are fixed on the base. When each column is folded, its upper part is respectively stuck in each U-shaped groove frame.

[0012] For the column with an upper part being a rotatable baffle tube structure: the upper section of the column is stuck in the U-shaped groove frame, forming the first rotational stop limit of the baffle tube.

[0013] Four corner protectors are fixedly connected to the base. Wedge blocks are fixedly connected to the upper sections of the columns. When the columns are unfolded, the wedge blocks on their upper sections are placed in the notches on the corner protectors.

[0014] Column with a rotatable pipe-blocking structure in the upper section: The wedge block is located on the upper section of the column and is placed in the notch on the corner protector, forming the anti-rotation limit II of the pipe-blocking. Description of the Drawings

[0019] In the figure: base 1, column 2 with a rotatable pipe-blocking structure in the upper section, upper section of the column 2-1, lower section of the column 2-2, pipe I 2-3, pipe II 2-4, limit hole 2-5, limit rod 2-6, ordinary column 3, corner protector 4, wedge block 5, U-shaped groove rack 6, part 7, pipe-blocking 8. Detailed Implementation Manner

[0020] As Figures 1-4 shown, a rack with rotatable columns, the rack includes a base 1 and four columns. Four corner protectors 4 are fixedly connected to the base 2. Each column is respectively installed in each corner protector 4 and is a foldable column. A wedge block 5 is fixedly connected to its upper section. When each column is unfolded, the wedge block 5 on its upper section is placed in the notch on each corner protector 4. Four U-shaped groove racks 6 are fixedly connected to the base 1. When each column 2 is folded, its upper section is respectively stuck in each U-shaped groove rack 6; several parts 7 are placed on the base 1;

[0021] The upper sections of the two left columns have a rotatable pipe-blocking structure (i.e., column 2 with a rotatable pipe-blocking structure in the upper section). The rotatable pipe-blocking structure includes a pipe-blocking 8, and the rotation angle of the pipe-blocking is 90°. The two right columns are ordinary columns 3. When the pipe-blocking 8 rotates and is placed in front of and behind each part 7, it forms the front and rear limits of each part;

[0022] The column 2 with a rotatable pipe-blocking structure in the upper section and the ordinary column 3 are both square columns;

[0023] The column 2 with a rotatable pipe-blocking structure in the upper section includes an upper-section column 2-1 and a lower-section column 2-2. A pipe Ⅰ2-3 is fixedly connected to the lower end of the upper-section column 2-1, and a pipe Ⅱ2-4 is fixedly connected to the upper end of the lower-section column 2-2. The pipe Ⅰ2-3 is inserted into the pipe Ⅱ2-4 and is rotatably connected thereto in a mating manner. The pipe-blocking member 6 is fixedly connected to the upper-section column 2-2. A limiting hole 2-5 is provided on the pipe Ⅰ2-3, and a limiting rod 2-6 is provided on the pipe Ⅱ2-4. The limiting rod 2-6 is placed in the limiting hole 2-5 and cooperates with the limiting hole 2-5 to form the rotational limit of the pipe-blocking member 6.

[0024] When the column 2 with a rotatable pipe-blocking structure in the upper section is folded, its upper-section column 2-1 is stuck in the U-shaped groove frame 5 to form the first anti-rotation limit of the pipe-blocking member 6.

[0025] The wedge block 5 on the column 2 with a rotatable pipe-blocking structure in the upper section is located on its upper-section column 2-1. When the column 2 with a rotatable pipe-blocking structure in the upper section is unfolded, the wedge block 5 on the upper-section column 2-1 is placed in the notch on the wrap-around angle 4 to form the second anti-rotation limit of the pipe-blocking member 7.

[0026] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
