Supporting column of suspension type commodity shelf

Abstract

The invention discloses a supporting column of a suspension type commodity shelf. The supporting column comprises a fixed pipe connected with a suspension fixing piece, a movable pipe in sliding fit with the fixed pipe, a motor connected with the suspension fixing piece, a lead screw connected with the motor through a transmission mechanism and driven to rotate, and a lead screw nut screwed with the lead screw. The lead screw nut is connected with the upper end of the supporting pipe; the lower end of the supporting pipe is connected with the movable pipe and the object carrying platform connecting piece through the movable pipe connecting piece; an axial limiting assembly for preventing the top end of the movable pipe from being lower than the top end of the supporting pipe so as to prevent the movable pipe and the object carrying platform connecting piece from being separated from the supporting pipe is fixed to the top end of the movable pipe; an external thread of the lead screw nut is screwed with an internal thread at the upper end of the supporting pipe; and an axial limiting structure for preventing the lead screw from being separated from a motor shell bottom plate connected with the suspension fixing piece is arranged between the top of the lead screw and the motor shell bottom plate. The supporting column can ascend and descend and does not shake in the ascending and descending process and the static state, and the movable pipe and the object carrying platform connecting piece can be prevented from falling off.

Description

technical field [0001] The invention relates to the technical field of indoor storage devices, in particular to a support column of a hanging storage rack. Background technique [0002] Garages, storage rooms, homes or offices generally require racks to place items. The traditional racks are floor-standing. In order to save indoor space, they are often changed to wall-mounted racks or hanging racks or inverted racks. Those are generally fixed on the ceiling or beams. Compared with floor racks and wall-mounted racks, hanging racks have the advantage of not occupying any space for people. [0003] And the supporting column of the hanging type storage rack of prior art or claims column or claims connection column, generally is fixed and can't lift, and it is all inconvenient to place or take article. And in order to realize lifting, prior art all adopts pulley pull rope device to lift, and loading platform is easy to shake in lifting process, and loading platform is not fixed...

AI Technical Summary

Problems solved by technology

[0003] And the support column of the hanging type storage rack of prior art or claims column or claims connection column, generally is fixed and can't lift, and it is all inconvenient to place or take articles.

In order to achieve lifting, the prior art uses a pulley and rope device for lifting. The loading platform is easy to shake during the lifting process.

However, if the lifting column of the electric lifting desk is used as the supporting column of the hanging shelf, there are at least the following disadvantages. Since the lifting column of the electric lifting desk is based on the ground to rise or fall, there is no anti-movement tube and The safety structure of the load platform connector and the load platform connected to it falls off or falls, and cannot be used as a support column for a suspended shelf

If the lifting column of the electric lifting desk is used as the supporting column of the hanging shelf, there are still disadvantages of not being able to bear strong axial tension and insufficient suspension strength
