Description

Technical Field

[0001] The utility model belongs to the field of ladder technology, and particularly relates to a multi-functional assembled ladder for performances. Background Art

[0002] The ladder for performances, usually called the stage ladder or performance ladder, is a commonly used auxiliary device in various performances, concerts, dramas, dances and other activities.

[0003] Currently, the Chinese utility model with the publication number of CN208950197U discloses a portable assembled ladder for a swimming pool, which includes a first side beam and a second side beam, and a plurality of treads connected between the first side beam and the second side beam. Both the first side beam and the second side beam are sequentially and detachably connected by a plurality of unit plates; positioning grooves and / or positioning protrusions are arranged on the mutually connected surfaces of the unit plates, and the positioning grooves and positioning protrusions on adjacent unit plates cooperate with each other. The unit plate is in a rhombus shape, and at least one insertion groove matching with the end of the tread is arranged inside the unit plate. The mutually connected surface of the unit plate is parallel to the tread, and a connecting protrusion is vertically arranged on the mutually connected surface of the unit plate. Dividing the side beam into several unit plates reduces the occupied space volume, facilitates stacking and transportation; the unit plates can be produced by the same mold and can be spliced and used on both sides of the tread, improving the installation flexibility and reducing the production cost; the detachable connection of the unit plates can meet the different needs of users, and the installation is convenient and easy to operate.
