Abstract

The utility model discloses a Y-shaped ladder made of glass fibre reinforced plastics, which is composed of a main leg, a supporting leg and a workbench. A plurality of tool holes are arranged on the workbench, the ladder legs and ladder steps are made of U-shaped glass fibre reinforced plastics, and anti-skid cushions are arranged under the ladder legs. The utility model is a multipurpose Y-shaped ladder which has the advantages of convenience, practicality, safety, stability and insulating property.

Description

The glass fiber reinforced plastic double ladder

The utility model relates to a kind of double ladder, specifically the glass fiber reinforced plastic double ladder.

Double ladder on the market has two types now, and a class is wooden double ladder, and another kind of is the metal double ladder.Wooden double ladder is not only heavy, and the no workbench of ladder end, uses extremely inconvenient.The double ladder of metal construction mostly is little square aluminium and makes, and step is narrower aluminum pipe, and terraced leg step forms for some contact riveted joint, and structure very built on the sand; The double ladder non-skid property of metal construction is poor, on-insulated, and easily rust is rotten.

It is a kind of easy to use, safe firm and the double ladder of insulating properties is arranged that the purpose of this utility model is to provide, in order to electric power, industry and civilian.

The purpose of this utility model is to realize like this.

A kind of glass fiber reinforced plastic double ladder, form by main leg, supporting leg and workbench, the top hinge joint of wherein main leg and supporting leg has workbench, workbench is provided with tooling hole, main leg, supporting leg and step adopt " " type glass fiber reinforced plastic to make, main leg is with to be face contact being connected of step fixedly connected, and the lower end of main leg and supporting leg is provided with slipmat; Riveted joint has self-locking strut, self-locking strut to make main leg and supporting leg be acute angle-shaped between main leg and supporting leg; Be provided with strut between main leg and step, supporting leg and cross bar.

During use, draw back main leg and supporting leg, make the locking of self-locking strut, workbench can be placed instruments such as hammer, pliers as required, and end of operation will be lifted on the self-locking strut, can be with the double ladder folding, so that deposit.

The utility model special structure design not only makes the double ladder structure firm, anti-skidding, and the tooling hole that is provided with of workbench, can insert common tool, thereby prevent the instrument landing, and be convenient to operation.The double ladder main member adopts pultrusion glass fiber reinforced plastic to make, and has the mechanical strength height, light and handy convenient folding, and electric insulation, corrosion-resistant, characteristics such as appearance luster is bright-coloured.
