Abstract

The invention provides a life-saving sling with a slow descent clip, and belongs to the articles in the fire fighting life-saving field. The life-saving sling with the slow descent clip is composed of the slow descent clip and a sling body, wherein the slow descent clip is composed of two metal pieces, one end of each metal piece is provided with an arc elbow, the same sides of the straight sections of the two metal pieces are connected through a hinge shaft, the center of the arc elbow stretching out of each metal piece is provided with a rectangular hole groove inclined inwards, the other same sides of the straight sections of the two metal pieces stretch towards the other side to form a plurality of hooks and a central rectangular-strip handle respectively, the hooks are arranged in a staggered mode, the inner faces of the straight sections of the two metal pieces are provided with a plurality of transverse protrusions which are staggered, the parallel sections of the transverse protrusions are semi-circular, a lower sliding rope fixed on a high position is clamped between the two metal pieces and in the upper hole groove and the lower hole groove, the sling body is an O-shaped nylon rope, the middle of the sling body is provided with a round ball with a round hole in a penetrating mode, the round ball serves as a sling tightening ball, and the upper end of the round ball is hung at the lower end of the lower hole groove of the slow descent clip. The life-saving sling is simple in structure, downward sliding speed can be controlled automatically, and many people can use the life-saving sling at the same time.

Description

The slow lifesaving rope sling that falls clip of band

One, technical field

The slow lifesaving rope sling that falls clip of band belongs to fire-extinguishing and lifesaving field articles for use, relates to descending lifeline and rope sling structure, particularly the structure of the slow lifesaving rope sling that falls clip.

Two, background technology

High building catches fire, and fixes the slow effect of falling that lifesaving rope sling people and weight utilize descending lifeline and make rope slow decreasing and make people's slow decreasing and escape in the lower abseiling of descending lifeline, if without descending lifeline, rope sling cannot delay and falls, and the recycling of downslide rope bothers.

Three, summary of the invention

The present invention be invention a kind of be connected in life line put have slow effect falls and slow fall clip stay abseiling and realize slow the falling effect of people and weight, the bands motionless and can many people's recyclings of restricting delay the lifesaving rope sling that falls clip.

1, technical scheme

The lifesaving rope sling that band is slow falls clip falls folder and rope sling forms by slow, the slow folder that falls respectively forms at the sheet metal of a headband arc elbow by two, connect with hinge axis at two metal sheets flat segments one homonymy, the hole slot of the side mouth of a rectangle tool in oblique is opened at the arc elbow center that every sheet metal stretches out, another stretches out crotch and rectangular handle of a centre bit of many dislocation two metal sheets flat segments to another sheet with side, two metal sheets flat segments inner face respectively has the transverse process that many dislocation parallel cut surface are semicircle, be fixed on the downslide rope clamp of eminence in two metal sheets and top and the bottom hole slot, rope sling is 0 shape nylon rope, middle part is installed with a ball with holes as tight cover ball, upper end hangs over the slow folder hole slot lower end, lower end that falls.

2, beneficial effect

Simple in structure, gliding speed can oneself be controlled, and can many people use simultaneously.

Four, brief description of the drawings

Fig. 1 is the slow lifesaving rope sling sketch that falls clip of band.

In Fig. 1: the slow 5 times abseilings 6 of folder 1 sheet metal 2 hinge axis 3 hole slot 4 crotches of falling

The tight cover ball of rope sling 78 handle 9 transverse process 10.

Five, detailed description of the invention

With reference to accompanying drawing 1, the slow corrosion resistant plate that falls thick 5 millimeters of folder 1 use is made material, sheet metal 2 is wide 6 centimetres, 20 centimetres of straight segment lengths, arc elbow is with one section of curved protruding 5 centimeter length of 10 centimetres of arcs of φ, 3 × 4 centimetres of hole slot 4 vertical slots at arc elbow center, 3 centimetres wide 3 centimetres on the lower side, side mouth, crotch 5 is wide 5 millimeters, 3 centimetres of arc length, on each, all there is 2-6 crotch 5, hinge axis 3 is 1 centimetre of φ, long 20 centimetres, lower abseiling 6 is 3 centimetres of nylon ropes of φ, rope sling 7 is the nylon rope of 2 meters of 3 centimetre of 0 shape total lengths of φ, tight cover ball 8 is the baton round of 5 centimetres of φ, there is the circular hole of 4 centimetres of φ at center.Handle 9 is 1 × 1 × 10 centimetres, and transverse process 10 tangent planes are the hemisphere of 5 millimeters.
