[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.
[0019] Please see Figures 1-4 This utility model discloses an adjustable storage rack, comprising a first side tube 1; a socket is provided on the side of the first side tube 1, and the socket is inserted and fixed to the side of a support tube 2; the support tube 2 is inserted and fixedly installed at the socket on the side of a second side tube 3; a square hole is provided at the top of the first side tube 1 and the second side tube 3, and an adjusting and fixing tube 4 is inserted and fixed in the square hole; an adjusting tube 5 is slidably connected inside the adjusting and fixing tube 4; a limiting block 6 with a limiting function is welded and fixed to the top side of the outer wall of the adjusting and fixing tube 4; a circular hole is provided on the front and rear sides of both the adjusting and fixing tube 4 and the adjusting tube 5, and a pin 7 is inserted and fixed inside the circular hole; an elastic retaining ring 8 is snapped and fixed at the rear end of the pin 7.
[0020] The end of the pin 7 is provided with a groove, and the groove engages and is fixed with the elastic retaining ring 8; the elastic retaining ring 8 is Ω-shaped.
[0021] Both the first side pipe fitting 1 and the second side pipe fitting 3 are set perpendicular to the supporting pipe fitting 2; the circular holes on the adjusting and fixing pipe fitting 4 and the adjusting pipe fitting 5 are spaced at the same distance.
[0022] The working principle of an adjustable storage rack, as described above, is as follows:
[0023] The first side fitting 1, the second side fitting 3, and the support fitting 2 are processed by laser cutting grooves and removing rounded corners using external equipment. Laser cutting improves the fitting accuracy of the first side fitting 1 and the second side fitting 3 during assembly. The first side fitting 1 and the second side fitting 3 are tightly fitted to the support fitting 2 using an embedded method. Then, spot welding is performed at the mating interface using an electric welding machine. Spot welding minimizes the deformation of the fittings and provides sufficient connection strength, ensuring that the overall storage rack meets the dimensional accuracy and performance requirements, and improving the production yield of the storage rack. The adjusting and fixing fitting 4 and the adjusting fitting 5 are connected and fixed through the laser-cut through holes and the pins 7. The adjusting fittings can adjust the spacing between different height layers according to the height of the items for storage.
[0024] This utility model provides an adjustable storage rack by improving the design. By setting an adjustable fixing pipe 4, an adjustable pipe 5, and a pin 7, it solves the problem that the spacing between layers is difficult to adjust according to the height of the items, thus adapting to the problem of different storage heights of various items.
