Abstract

The invention relates to a multipurpose rope ladder which comprises a hanging rack, a metal chain and foot bars, wherein the hanging rack consists of two metal pipes which are bent multiple times to form a hook on the upper part and a support leg on the lower part; two groups of four-connecting-rod mechanisms consisting of connecting plates and four connecting rods are arranged between the two metal pipes; the metal pipes are hinged with the connecting rods, and the connecting rods are hinged with the connecting plates; two springs are arranged between two connecting rods respectively arranged at the upper side and the lower side of each connecting plate; one end of the metal chain is connected with the metal pipe on the lower side of the hanging rack through a connecting ring; and the foot bars are fixedly mounted in a horizontal interval mode along the vertical direction of the metal chain. The multipurpose rope ladder provided by the invention is convenient to use, has high strength, prevents fire and can be used as a firefighting product.

Description

Use rope ladder more

Technical field

The present invention relates to a kind of rope ladder of using more.

Background technology

Traditional rope ladder generally forms lanyard at the two ends of treadle, the deficiency of its existence is: the ageing resistance of rope is poor, and is inflammable, intensity is low, and fixing difficulty is waved greatlyyer in the use, use inconvenient.

Summary of the invention

The purpose of this invention is to provide a kind of many rope ladders of use, easy to use, intensity is high, fire prevention, can be used as fire service inventory, overcome use in the existing product inconvenient, the deficiency of aspect such as intensity is low, and is inflammable.

The objective of the invention is to be achieved through the following technical solutions:

A kind of rope ladder of using more, comprise hanger, metal bracelet and treadle, repeatedly the bending back forms hook on top to hanger, leg is formed at the bottom by two strip metal pipes, between two strip metal pipes, be provided with by junction plate and four two groups of quadric chains that connecting rod is formed, between metal tube and the connecting rod, all be articulated and connected between connecting rod and the junction plate, between two connecting rods of junction plate upside and downside, be provided with two springs; One end of metal bracelet is connected by the metal tube of connecting ring with the hanger downside, and treadle is along the fixed interval installation in a horizontal manner of metal bracelet vertical direction.

Beneficial effect of the present invention is: easy to use, intensity is high, the fire prevention, can be used as fire service inventory.
