Example 1

The present invention is composed of several basic modules 1 connected. The basic module 1 can be made of nylon 66 and glass fiber mixed material or other materials through thermoforming process. The surface of the basic module 1 has a certain roughness, which is more conducive to climbing and will not slip. One side of the basic module 1 is a tenon 2 structure, and the other side is a tenon 3 structure. Insert the tenon 2 on one side of one basic module 1 into the tenon 3 on the other side of the other basic module 1, and the two basic modules 1 That is, horizontal plug connection. By analogy, enough basic modules 1 can be connected horizontally as required, and this connection makes the structure connected in rows a relatively rigid body structure. There are two right-angle grooves 10 at the right angles on the upper and lower sides of the front of the basic module 1, and the connecting pipe 4 can be inserted into the upper and lower sides of the basic module 1 by using steel pipes. Connecting sheet 5, namely a hole of the two-hole steel sheet; another block or another group of basic modules 1 is on the top or bottom of the module or module group, and the two-hole steel sheet that exposes the top or bottom of the module or module group to the outside Insert the other half of the corresponding right-angled groove 10, then insert the steel pipe into this side, and also insert it into the other hole of each two-hole steel sheet in this side at the same time, so that two or two groups of basic modules can be connected 1 connected together. There are steel pipes on the top and bottom of the net-shaped whole to pass through and be fixed with one hole of all exposed two-hole steel sheets. Because the connecting piece 5 is that the two-hole steel sheet can only rotate in one direction with the steel pipe as the center in the right angle groove 10, after being connected into a net-like whole, the lifesaving net can only be rolled in one direction. Theoretically, a lifesaving net of any size with the base module 1 as a smaller unit can be formed. The fixed carbine hook on the steel pipe of its upper end can make it fast be fixed on the rescue facility;

Example 2

The row of basic modules 1 at the top of the lifesaving net is divided by the center of the row. The mortise 2 and mortise 3 of the left module are red; the mortise 2 and mortise 3 of the right module are green. According to international practice, the principle of red on the left and green on the right is convenient and quick to confirm the correct use direction of the lifesaving net.

Example 3

After the upper end of the life-saving net is quickly fixed on the rescue facility by the carbine hook, it is lowered to the side of the rescued person. Due to the effect of the fluorescent coating on both sides of the basic module 1, the rescued person can easily find the rescue target. For the rectangular frame structure of the basic module 1, the preferred external dimensions are 170mm×140mm×20mm, and the internal dimensions of the frame are 120mm×90mm×20mm; It is easy for the rescued person to grasp and climb up. Because its structure is a relatively rigid body, deformation and winding will not occur when people climb, thus making climbing easier and faster.

When in use, use the carbine hook on its upper end to hang on the rescue facility, then unfold it vertically downwards, and make its lower end close to the rescued person. Once the rescued person grasps it, they can climb up and get out of danger. territory. Since the side to be climbed is a relatively rigid side, climbing will be very easy. If the rescued person is unable to climb, the person in distress can be pulled to its lower end by the rescuer, the lower end is passed around the body of the rescued person and rolled up, and the rescuer at the upper end pulls the lower end with a rope 6. Pull the rope 6, the rescued person will be rolled up, and the rescued person will be rescued. It is also possible to hang the ropes 6 at its upper and lower ends with a sling at the same time, so that its horizontal direction is relatively rigid in the shape of a hanging basket. re-injury, the rescue effect is very significant.

The above-mentioned detailed description of the modular multipurpose lifesaving net with reference to the embodiment is illustrative rather than restrictive, and can be made into various specifications according to needs, so changes and modifications without departing from the general concept of the present invention, Should belong to the protection scope of the present invention.
