Problems solved by technology

[0003] As mentioned above, the existing rope patents and research results realize self-locking by buckles or rope clips. Although it is convenient and effective, the structure is more complicated, and the self-tightening fixation and simple release of the rope cannot be realized.

Embodiment 1

[0022] Strapping - see Figure 5 described as follows:

[0023] First close the pressure relief valve 21, then wind the Bourdon tubular hollow rope 1 around the bundle 8, so far, the preparatory work is completed, and the bundle can be started. The pumping rod 26 moves to start pumping air. At this time, the one-way valve I22 is opened, and the one-way valve II23 is closed. The gas in the Bourdon tubular hollow rope 1 enters the cylinder 24 through the one-way valve I22. When the pumping rod 26 moves to When at the limit position, the pumping ends, and the one-way valve I22 is closed. When the pumping rod 26 reversely moves, the one-way valve II23 is opened, the one-way valve I22 is closed, the gas in the cylinder 24 is discharged through the one-way valve II23, and enters the atmosphere, and the exhaust process ends. The pumping rod 26 reciprocates to perform the pumping and exhausting process repeatedly. Since one end of the Bourdon tubular hollow rope 1 is closed, the int...

Embodiment 2

[0025] Suspension - Suspension is used in much the same way as strapping

[0026]Firstly close the pressure relief valve 21, then wrap the Bourdon tubular hollow rope 1 on the binding object, so far, the preparatory work is completed, and the fastening and fixing can be started. The pumping rod 26 moves to start pumping air. At this time, the one-way valve I22 is opened, the one-way valve II23 is closed, and the gas in the Bourdon tubular hollow rope 1 enters the cylinder through the one-way valve I22. When the pumping rod moves to the limit position , the pumping ends, and the one-way valve I22 is closed. When the pumping rod moves in reverse, the one-way valve II23 is opened, and the one-way valve I22 is closed, and the gas in the cylinder passes through the one-way valve II23, is discharged from the cylinder by the pumping rod 26, and enters the atmosphere, and the exhaust process ends. The pumping rod 26 reciprocates to perform the pumping and exhausting process repeatedl...

Embodiment 3

[0029] According to the use requirements of the rope, the air suction device 2 can be replaced by an automatic suction pump, and the air pressure in the rope can be changed by electric or other power methods, causing the "tightening" and "releasing" actions of the Bourdon tubular hollow rope . According to the use environment of its rope, the pressure regulating medium in the rope body can be gas or liquid.

[0030] The main working principle remains roughly the same. First, the pressure relief valve 21 is closed, and then the Bourdon tubular hollow rope 1 is wound on the tying object. At this point, the preparatory work is completed, and the tying can be started. The pumping device starts pumping, and now the one-way valve I22 is opened, and the gas in the Bourdon tubular hollow rope is extracted through the one-way valve I22, and when the pumping ends, the one-way valve I22 is closed. Since one end of the Bourdon tubular hollow rope is closed 11 , the interior of the Bourdo...

Abstract

The invention relates to a self-tightening rope which belongs to rope tools used in daily production, daily article binding, fire rescue, climbing rescue, hoisting and other high-altitude operation. The rope comprises a Bourdon tubular hollow rope (1) and an exhaust device (2); one end of the Bourdon tubular hollow rope (1) is a closed end (11), and the other end of the Bourdon tubular hollow rope (1) is communicated with the exhaust device (2); the pressure borne by the Bourdon tubular hollow rope (1) is controlled by the exhaust device (2); the surface of the Bourdon tubular hollow rope (1)is provided with a rubber layer for increasing the friction force or a rough surface layer with bosses; and a flexible metal material (5) which cannot be expanded is jointed on the surface of a Bourdon outer ring of the Bourdon tubular hollow rope (1) and is used for improving the curvature and enhancing the toughness of the Bourdon rope when the Bourdon tubular hollow rope bears pressure and deforms. Because the self-tightening rope can realize quick binding and 'release' and plays a self-tightening role after binding, the rope is applicable to rope application fields which require quickness, convenience and reliability.

Description

technical field [0001] The invention relates to a rope tool used in the fields of high-altitude operations such as daily production, bundling articles in daily life, fire rescue, climbing, and hoisting. In particular, it refers to a rope that can realize self-tightening function without knotting after simple winding. Background technique [0002] Along with the progress of science and technology, the rope that various composite materials are made is more and more tough, but relative to the tough and strong rope itself, the binding of rope is often the main reason that various accidents related to rope take place at present. At present, the binding and fixing methods for ropes mainly include: manual knotting, special connection buckles, and rope locking devices, but none of them can achieve the purpose of safety and fast fixing of ropes. Such as the patent "the tie-down device that can tighten the rope" (patent No. 86202862) is a kind of tie-down device that serves in daily ...
