A desk having a bottom plate, a face plate movably coupled to the bottom plate by one or more support members, a motor configured to selectively move the face plate upward and downward with respect to the bottom plate, and a control mechanism. The control mechanism can have a first sensor device coupled to an upper surface of the bottom plate, the first sensor device having one or more first optical sensors, and a second sensor device aligned parallel to the first sensor device and coupled to a lower surface of the face plate, the second sensor device having one or more second optical sensors in communication with the one or more first optical sensors. The control mechanism can be configured to stop the motor from moving the face plate in response to an object between the first sensor device and the second sensor device.

The present invention discloses a lifting working-platform used on a desktop, has an upper platform, and the side surfaces of upper platform are provided with side plates. The lifting working-platform prevents potential injury of hands if accidently inserting inside during the lifting process of the upper platform and greatly facilitates the installation of a power socket, and avoids outside collision to the plug; and the appearance is appealing; articles such as staplers, erasers and pens can be received in the hanging bucket, thereby ensuring convenience in fetching these articles and reducing occupied space of the lifting working-platform and the desktop, such that the lifting working-platform and the desktop become clean and orderly.

The present disclosure discloses a desk-mounted lifting platform comprising a workbench, an upper support and a low support. The workbench is connected to the upper support. A first lifting arm and a second lifting arm are arranged between the upper support and the lower support. The first lifting arm and the second lifting arm are X-shaped and hinged at an intersection thereof. An upper end of the first lifting arm is hinged with the upper support. A lower end of the first lifting arm is slidably fitted on the lower support. A lower end of the second lifting arm is hinged with the lower support. An upper end of the second lifting arm is slidably fitted on the upper support. A gas spring is arranged between the upper support and the lower support. The gas spring is used for providing a lifting force to lift the upper support.

A stepless adjustable telescopic device includes a first support, a second support, and a folding arm connecting the first support to the second support. The folding arm includes a first quadrangular structure, a second quadrangular structure, and a power support device connected to the first quadrangular structure. A first end of the first quadrangular structure is rotatably connected to the first support. A first end of the second quadrangular structure is rotatably connected to the second support, and a second end of the second quadrangular structure is rotatably connected to a second end of the first quadrangular structure via a rotary connection structure. The power support device and the first quadrangular structure form a triangular structure, and the power support device is configured to drive the first quadrangular structure to rotate such that the first quadrangular structure drives the second quadrangular structure to rotate synchronously with the first quadrangular structure.

A portable modular folding table can include a substantially flat tabletop having three or more tabletop sections, hinges coupled to the tabletop sections, and collapsible legs that are modular and separate from the tabletop. The tabletop can have a width and a length that is at least twice as large as the width, and the tabletop sections are coupled to and foldable onto each other to reduce the length of the tabletop by less than half when the tabletop is reduced from a fully extended configuration to a fully compacted configuration. Each of the collapsible legs can be adjustable to multiple different heights and can have multiple tabletop support points. The tabletop can rest atop the tabletop support points when the tabletop is in a fully extended configuration and the tabletop can be separated from and stored alongside the collapsible legs when the tabletop is in a fully compacted configuration.

A table includes a tabletop and a leg assembly to support the tabletop. The leg assembly includes first and second supports each movably connected with the table top. The leg assembly also includes an adjustable bar disposed substantially perpendicular to a height direction of the leg assembly. The adjustable bar has a first end connected with the first support and a second end connected with the second support such that changing a length of the adjustable bar changes a height of the leg assembly.
