detailed description

The structure of the portable multifunctional lifeline of the present invention will be described in detail below in conjunction with the accompanying drawings.

The portable multifunctional lifeline shown in FIG. 1 includes: a storage bin 2 and a lifeline body stored in the storage bin 2 . The lifeline body includes: a main steel rope 3 , a floating body steel rope 4 , an auxiliary steel rope 6 , a floating ball 7 , a tensioner 8 , a plurality of grasping aid strings 9 and a sinking body steel rope 10 . In addition, a handle 1 is also installed on the storage bin 2, which is convenient for the rescuer to grasp.

One end of the main steel rope 3 is fixed on the inner wall of the storage bin 2, and the other end is equipped with a floating ball 7. There are 2 tensioners 8, which are installed on the main steel rope 3 at intervals, and each tensioner 8 has two arms that can be gradually opened. The two ends of the buoyant steel rope 4 are respectively connected with the outer ends of the arms on the same side of the two tensioners 8; End connection, that is, when both tensioners 8 are opened, the floating body steel rope 4 and the sinking body steel rope 10 are located on both sides of the main steel rope 3 respectively.

There are many auxiliary steel ropes 6, one end of each auxiliary steel rope 6 is connected to the buoyant steel rope 4, and the other end is connected to the buoy 7 or the handle 1, so as to enhance the overall strength of the lifeline.

As shown in the figure, a plurality of grasping aid strings 9 are interwoven in a net shape, and the two ends of each grasping aid string 9 are respectively connected to the two arms of the two tensioners 8, or connected to the floating body steel rope 4 and the sinking body steel rope respectively. Rope 10, like this, along with the opening of two slow-tensioners 8, the net that a plurality of roots help to catch thin rope 9 to weave opens, thereby can increase the probability that the rescued person catches lifeline.

Although not shown in the figure, as an improvement, in order to enable the lifeline body to be opened quickly, a pop-up device for ejecting the lifeline body can also be installed in the storage compartment 2, and an ejection device for activating the lifeline body can be installed on the outer wall of the storage compartment 2. switch. When the lifeline needs to be opened, the switch is activated, and the ejection device quickly ejects the lifeline body to rescue the rescued.

In order to improve the strength, a plurality of thicker reinforcing steel ropes 5 are also connected between the two arms of the two tensioners 8 . The length of buoyant body steel rope 4 and sinking body steel rope 10 is less than or equal to the length of main steel rope 3 between two slow tensioners 8, so that the net-like interweaving helps grasp thin rope 9 and can open smoothly. Taking the main rope as an example with a length of 10 meters, the length of the floating body steel rope 4 and the sinking body steel rope 10 is more suitable at 8-9 meters; the angle of the tensioner can be 90 degrees or more to adjust the opening area of the rope net. .

In order to reduce the overall weight of the device and facilitate the lifeline to float in the water, the storage bin 2, the handle 1 and the tensioner 8 can be made of light engineering plastics or other suitable materials. The main steel rope 3, the floating body steel rope 4, the auxiliary steel rope 6, the grasping string 9 and the sinking steel rope 10 can be made of high-strength and lighter high-molecular polyethylene fibers, or by other suitable materials production.

In one embodiment of the present invention, the diameter of the main line rope is 0.5 mm, the length is 10 meters, and the tensile force is more than 200 kilograms; the diameter of other line ropes is about 0.2 mm. The color of the rope can be selected from bright red or orange commonly used in lifesaving equipment for easy identification.

The floating ball material can adopt solid buoyancy material. For example, it can be a solid compound obtained by filling an organic polymer material with an inorganic light filler material and undergoing a physical and chemical reaction. The solid buoyancy material is a polymer ^- based solid material with low density, high strength, and less water absorption. application requirements.

The tensioner is made of engineering plastics, light in weight, and has a columnar shape after being stowed away. It opens automatically after being thrown out, and expands a single rope into a lifesaving net, increasing the chances of those who fall into the water to catch the lifeline.

The using method of lifeline of the present invention is as follows:

When the lifeline body is thrown out of the storage bin 2, the tensioner 8 is gradually opened, and at the same time, one side of the floating body steel rope 4 floats up, and one side of the sinking body steel rope 10 sinks, and a plurality of grasping strings 9 are placed on the side of the slowing body. Open under the effect of tensioner 8 and be netted. Because the density of the rope and net material of the device is lower than that of water, it can float quickly under the action of the floating ball. In order to make the lifeline float quickly, other buoyant materials can also be added.

In addition to being used as a lifeline for falling into the water, the lifeline device of the present invention can also be used as a hammock and a hanging rope for mountain climbing, rock climbing or fire escape. When used as a hammock, a hook is added to the floating ball at the front end and the handle at the rear, and the device is lifted to be used as a hammock, which is convenient for outdoor rest. When used as a life-saving sling: add a hook to the front end of the device and bind the tensioner, and then fix it on a tree trunk and other objects, it can be used as a safety (traction) rope for cliff hanging or mountain climbing.
