A telescopic tube assembly includes an outer tube and an inner tube which is telescopically inserted in the outer tube. A first stabilizing unit and a second stabilizing unit respectively located in a gap between the inner and outer tubes to make the inner tube stably moved relative to the outer tube. The first stabilizing unit includes two plates. The outer surface of each of the two plates is in contact with the inner surface of the outer tube, and the inner surface of each of the two plates is in contact with the outer surface of the inner tube. The inner tube is assembled to the outer tube by the first and second stabilizing units.

The present disclosure relates to the field of office furniture, and more particularly to an electric lift table control system and method that realize a resistance back-off. The system comprises a controller, a table (1) and a lifting column (2) for driving the table to move vertically, the lifting column (2) is connected with the controller signal, and further comprises at least one arranged under the table (1) a safety grating (3) for detecting obstacles, each set of safety gratings comprising a transmitting end assembly and a receiving end assembly, and a gap is provided between the safety grating (3) and the lower surface of the table (1), and said The safety light barrier (3) is connected to the controller signal. This will control the lifting column to stop working before encountering obstacles.

A height adjustment mechanism for an adjustable height table includes an outer sleeve, an inner sleeve, a plug, and a locking mechanism. The outer sleeve is disposed outside the inner sleeve, and the outer sleeve and the inner sleeve are slidable relative to each other. The plug is disposed outside the inner sleeve, and is slidably connected to the inner sleeve. The plug is disposed at an upper end of the outer sleeve, and an outer wall of the plug includes a pressing portion. The locking mechanism operates to push the pressing portion tightly against an outer wall of the inner sleeve to increase the friction between the plug and the inner sleeve, so that the plug and the inner sleeve are relatively fixed.

A vertically adjustable desk with an under carriage mounting system is described. The vertically adjustable desk may have a planar work surface and telescoping support legs which are operable to raise and lower the work surface. The vertically adjustable telescoping support legs may be height adjustable by at least one electronic motor. The under-carriage mounting system may include a first and a second U-shaped support bracket that each receives a first and second runner support, the U-shaped brackets affixed to respective first and second vertically adjustable telescoping support legs. The U-shaped support brackets may be used to mount accessories underneath the work surface.

An advanced laptop Bag that can converts into a portable work desk via extendable and adjustable legs housed on all 4 sides at the bottom of the laptop bag so it can turn into a sturdy work desk and has a waterproof PORTABLE USB charging station, anti-theft unit, and a cup holder. The Portable Desk Laptop Bag will be designed comparable to most Laptop Bag but will separate itself from all Laptop Bags as it can turn into a work desk. Prior designs of Laptop Bag stopped at being a housing unit for laptops and supplies where mine has advanced the Laptop Bag by adding adjustable legs at all sides of the bottom of the Laptop Bag to enable the Laptop Bag to be used as a work desk for the laptop while also being a housing unit for the laptop and supplies.
