A lifting desk is related to fields of lifting desks. The lifting desk includes a drive device, a gearbox, a desktop, a crossbeam, and a lifting column, the crossbeam being connected to the desktop, the lifting column being connected to the crossbeam, the gearbox including a gear assembly, the drive device being in driving engagement with the gear assembly, the gear assembly being in driving engagement with the lifting column; the lifting desk further includes a retaining plate, the retaining plate being securely connected to the desktop, the gearbox being connected to the retaining plate. The desk offers an advantage that the structure disclosed may enhance assembly precision of the lifting desk and enables lifting control of the desktop.

Height-adjustable work table, preferably kitchen table comprising at least one cabinet on top of which a table top is located. The cabinet(s) is located on a number of electrically driven height-adjustable platforms. In that the platforms are mutually retained by at least one connection rail these appear as stable both during the assembly of the work table and of the assembled table. Between a surface, typically a floor on which the platform is located, and an underside of the cabinet a toe kick is placed. This toe kick is telescopic in height such that the toe kick regardless of the adjusted height of the kitchen table shuts off access under the cabinet. The connection rail may constitute an element of the telescopic toe kick.

Height adjustable angled desks are disclosed herein. An example height adjustment system includes a drive system including: a worm gearbox; a motor operatively coupled to the worm gearbox to drive the worm gearbox; and an output shaft operatively coupled to the worm gearbox, the output shaft extending in a first horizontal direction; and an interconnection gearbox coupled to the drive system, the interconnection gearbox to convert rotation of the output shaft to rotation of an interconnection shaft in a second horizontal direction different than the first horizontal direction, the interconnection gearbox including a first cover coupled to a second cover of the worm gearbox, the output shaft extending through the interconnection gearbox.

A modular linear actuator and a height adjustable desk. The modular linear actuator comprises an actuator body module and a motor box module, the motor box module is detachably mounted at an end portion of the actuator body module, and the motor box module outputs the power of a motor to the actuator body module by means of a transmission device. The height adjustable desk comprises a desk plate, a desk frame, and the modular linear actuator. The desk frame is mounted on the actuator body module of the modular linear actuator. The modular linear actuator can be detached and recycled when being scrapped, which reduces the recycling cost and prolong the service life of a product. The motor box modules having different motor models are matched and combined with a plurality of actuator body modules. It enables the use of fewer product types to satisfy more performance requirements.
