DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model aims to provide a washbasin stand with adjustable height to solve the problems existing in the prior art. The height of the washbasin stand can be adjusted according to the height of the user group, and the installation is simple and the adjustment is convenient.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model provides a washbasin stand with adjustable height. Figure 1-Figure 7As shown, it includes a connecting leg 1, a storage board, a storage rack 3, a connecting rod 4 and a telescopic component. The four corners of the storage board are provided with plug-in parts. The storage board is provided with three layers and includes an upper storage board 30, an intermediate storage board 31 and a lower storage board 32. The storage rack 3 is fixedly connected to the plug-in part of the upper storage board through the connecting rod 4, the upper storage board is fixedly connected to the plug-in part of the intermediate storage board through the telescopic component, the intermediate storage board is fixedly connected to the plug-in part of the lower storage board through the connecting rod 4, and the connecting leg 1 is fixedly connected to the plug-in part of the lower storage board. The telescopic assembly includes a U-shaped part, a telescopic inner cylinder 5 and a telescopic outer cylinder 6. Two oppositely arranged telescopic inner cylinder through holes 2-1 are provided at the end of the telescopic inner cylinder. A boss protruding toward the outer surface is respectively provided at both ends of the U-shaped part. When the two ends of the U-shaped part are compressed inwardly, the U-shaped part can enter the interior of the telescopic inner cylinder, and the boss is snapped into the telescopic inner cylinder through hole 2-1. The telescopic inner cylinder 5 is slidably connected to the inner wall of the telescopic outer cylinder 6. The telescopic outer cylinder 6 is provided with a plurality of adjustment holes 7 along the axial direction, and the boss 8 matches the shape of the adjustment hole 7.

[0031] In this device, four connecting legs 1 are respectively fixedly inserted in the plug-in parts at the four corners of the lower storage board 32, the lower storage board 32 is inserted into the middle storage board 31 through the connecting rod 4, the middle storage board 31 is inserted into the upper storage board 30 through the telescopic assembly, and the upper storage board 30 is inserted into the storage rack 3 through the connecting rod 4, so that each connecting leg 1 and the corresponding connecting rod 4 and telescopic assembly are on a vertical line, and the four supporting points form a square structure, making the supporting structure more stable and easy to install. The telescopic assembly uses the deformation of the two ends of the U-shaped piece during compression, and the U-shaped piece can enter the interior of the telescopic inner tube, and can clamp the boss to the through hole 2-1 of the telescopic inner tube, and then clamp the boss to the adjustment hole of the telescopic outer tube. The structure is simple and easy to operate. When users of different heights use the telescopic assembly, they can press the boss 8 to retract it into the adjustment hole 7. At this time, the telescopic inner cylinder can slide inward relative to the telescopic outer cylinder, changing the length of the telescopic assembly, that is, changing the overall height of the washbasin rack. Thereafter, the boss is aligned with the adjustment hole of a suitable height, and the U-shaped piece restores its elastic deformation and squeezes the boss to be clamped on the adjustment hole, thereby fixing the relative position of the telescopic inner cylinder and the telescopic outer cylinder, thereby realizing the adjustment of the height of the washbasin rack and making it more convenient to use.

[0032] In this embodiment, the storage board is fixedly connected with the storage board side panels 9 around, and the plug-in part is a plug-in sleeve 10 that runs through the top and bottom. The plug-in sleeve 10 is arranged at the connection between two adjacent storage board side panels, and the connecting leg 1 and the lower storage board 32, the connecting rod 4 and the middle storage board 31, and the telescopic assembly and the upper storage board 30 are all fixedly connected through the plug-in sleeve 10. By setting the storage board side panels 9, it is more convenient to take the items hanging on the washbasin rack and prevent the items from falling from the washbasin rack. By setting the plug-in sleeve 10, the technical effect of simple installation and firm structure is achieved.

[0033] In this embodiment, a limiting platform is provided inside the plug-in part, and the plane where the limiting platform is located is flush with the plane where the storage plate is located. The limiting platform is used to limit the position where the connecting rod 4 is plugged into the plug-in part, and the plane where the limiting platform is located is set to be flush with the plane where the storage plate is located, so that the upper and lower parts of the plug-in part are subjected to more balanced force when they are squeezed against each other, and the situation where the connecting rod 4 on one side is not dislodged and the storage plate falls off is avoided, ensuring that the frame of the washbasin rack is more solid.

[0034] In this embodiment, the telescopic assembly further includes a sleeve 11 and a protrusion 12. The sleeve 11 is slidably sleeved on the outer wall of the telescopic inner tube 5, and the sleeve is used to be inserted into the gap between the telescopic inner tube and the telescopic outer tube, so that the structure of the telescopic assembly is more stable. One end of the protrusion 12 is fixedly sleeved on the outer wall of the telescopic outer tube 6, and the other end of the protrusion 12 is fixedly inserted into the plug-in sleeve 10. The lower end of the protrusion 12 is fixed to the upper end of the telescopic outer tube 6, and the upper end of the protrusion 12 is fixed to the plug-in sleeve 10 of the upper storage board 30, and the cross-sectional area of ​​the lower end of the protrusion 12 is larger than the cross-sectional area of ​​the upper end, so that the frame of the washbasin rack is more stable.
