Multifunctional mobile office vehicle

Abstract

The invention discloses a multifunctional mobile office vehicle, including a base, an upper column, a lower column, a television installation mechanism and a tray. The lower column is fixedly installed on the base. The underside of the base is provided with wheels. The upper column can be slidably inserted in the lower column. The television installation mechanism and the tray are respectively fixedly installed on the upper column. The multifunctional mobile office vehicle is characterized by also including a locking device and a telescopic support part. Both ends of the elastic telescopic direction of the telescopic support part are respectively fixedly connected with the upper column and the lower column. The locking device can achieve the fixed position of the upper column and the lower column. A friction part and a driving part are arranged on the upper column in the multifunctional mobile office vehicle and the friction part along the upper column is radially moved through driving to make the friction part and the lower column against friction or loose, thereby achieving the locking and positioning of the upper column and the lower column. A drive device utilizes an eccentric shaft with a handle, which can achieve locking by one spin and can achieve loosening by another spin, and has the advantages of simple structure, convenient operation and low manufacturing cost.

Description

technical field [0001] The invention relates to a floor-standing TV bracket, in particular to a multifunctional mobile office vehicle. Background technique [0002] At present, large family living rooms, conference rooms, public places, etc. need to use floor-standing TV stands. The TV sets on the floor-standing TV stands and the trays for placing audio-visual equipment used with the TV need to be lifted up and down. It is all realized by the relative sliding of the upper column and the lower column. After the relative position adjustment of the upper column and the lower column is completed, a locking device is required to make the two relative fixed positions. At present, a buckle mechanism is used to realize the locking of the two. Positioning, but this structure can only realize that the upper column and the lower column are fixed at the relative position of the buckle, and the fixed positioning of the two cannot be realized at any position. Contents of the invention ...
