Abstract
The utility model relates to a safety belt friction type buffer, which comprises a U-shaped plastic pipe, a safety rope belt and a connection ring. The U-shaped plastic pipe is provided with a curved bent pipe part and two vertical straight pipe parts which are correspondingly arranged. A placing groove and a channel which surrounds longitudinally and can be inserted into the safety rope belt are arranged on the outer side surface of the U-shaped plastic pipe; zigzag teeth are respectively arranged on the inner side surface of the U-shaped plastic pipe on the flat straight surfaces of the two straight pipe parts. A thin nylon rope is transversely wound on the outer layers of the folded pipe walls of the two straight pipe parts, and a rubber sleeve pipe is sheathed on the outer surface of the thin nylon rope. The utility model has the advantages of simple structure and light weight; when the utility model is used, the safety rope belt carries out slow sliding friction in the channel of the safety rope belt to achieve shockless braking.
Description
The utility model relates to the safety belt of ascending a height, the friction-type buffer on particularly a kind of safety belt of ascending a height.
Safety buffer on the existing safety belt has disk type and rolls over two kinds of belts, adopts the compression spring respectively and tears belt to produce resistance, and then play the effect of buffering.But the weight of these buffers is all very heavy, can reach about 1000 grams, uses and quite feels inconvenience.
The purpose of this utility model provides a kind of safety belt friction-type buffer, and it utilizes maximum quiet frictional force and force of sliding friction to reach buffering effect, and it is simple in structure, and weight is lighter.
A kind of safety belt friction-type buffer described in the utility model, it comprises U-shaped plastic tube and the safety rope belt that is sleeved on the U-shaped plastic tube, and coupling ring, described U-shaped plastic tube has bent tube section and two straight parts of a bending, the lateral surface of U-shaped plastic tube is provided with safety rope belt putting groove and safety rope belt passage vertical wraparound, that can embed safety rope belt, and the medial surface of U-shaped plastic tube is respectively equipped with saw shape tooth on the straight surface of its two straight-tube portions; Two straight-tube portions of described U-shaped plastic tube close up that the tube wall of shape is outer laterally to twine thin nylon rope, at outer surface suit one gum sleeve of thin nylon rope, so that safety rope belt sliding friction and reach buffer-braking lentamente in the safety rope belt passage.
The utility model utilized object before sliding maximum static friction force and the object sliding process in the force of sliding friction that produced, maximum static friction force has formed the maximum impact force of safety rope belt in the process of being hit, force of sliding friction then utilizes safety rope belt to slide a segment distance in buffer, thereby reaches the effect of shock absorbing power.The utility model is simple and reliable for structure, and weight is lighter, and buffering effect is obvious.After using the utility model, the impulsive force that falls from high altitude that safety belt bore can be reduced to below 50% of former impulsive force.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of structural representation of safety belt friction-type buffer.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the U-shaped plastic tube structural representation in the buffer.
Fig. 4 is the vertical view of Fig. 3.
Fig. 5 is by left view shown in Figure 3.
Fig. 6 is by right view shown in Figure 3.
Fig. 7 is the enlarged drawing shown in Fig. 1.
Referring to Fig. 1 to Fig. 7, a kind of safety belt friction-type buffer comprises U-shaped plastic tube 1, safety rope belt 2 and coupling ring 3.U-shaped plastic tube 1 has bent tube section 11 and two straight parts 12 of a bending.
The lateral surface of U-shaped plastic tube 1 is provided with the safety rope belt putting groove 21 and the safety rope belt passage 22 of vertical wraparound.Safety rope belt putting groove 21 is arranged on the edge of safety rope belt passage 22, and safety rope belt 2 can successfully embed in the safety rope belt passage 22 by safety rope belt putting groove 21.
The both sides of the bent tube section 11 of U-shaped plastic tube 1 are provided with to be convenient to safety rope belt 2 and to embed and subtract power groove 23 in the safety rope belt passages 22, makes when embedding safety rope belt 2 more convenient laborsaving.The outer surface of the bent tube section 11 of U-shaped plastic tube 1 is provided with square shaped teeth 13, to strengthen the frictional resistance of safety rope belt 2 when sliding.The interior lateral bending shape hole 18 of the bent tube section 11 of U-shaped plastic tube 1 is the mounting hole shape, so that the coupling ring 3 of institute's suit rotates flexibly in the hole.
The medial surface of U-shaped plastic tube 1 saw shape tooth 14 on its flat surface when the straight surface of its two straight-tube portions 12 is provided with saw shape tooth 14, two straight-tube portions 12 respectively and is closing up intermeshes and tightens up.Two straight-tube portions 12 of U-shaped plastic tube 1 close up the thin nylon rope 15 of the outer laterally winding of tube wall of shape.The outer surface of the straight-tube portion 12 of U-shaped plastic tube 1 is provided with thin nylon rope and tightens groove 16, so that two straight-tube portions 12 that thin nylon rope 15 will close up are around pricking tightlyer.The two ends of the straight-tube portion 12 of U-shaped plastic tube 1 are respectively equipped with thin nylon rope block 17, to stop that thin nylon rope 15 pitch of the laps are to the outside.Outer surface suit one gum sleeve 17 at thin nylon rope 15 to protect thin nylon rope 15 not frayed, prolongs the Acceptable life of this buffer.
When the utility model uses, coupling ring 3 is connected on the safety belt that lies in human body by a hook, an end of safety rope belt 2 is fixed on by hook can suspension place.The utility model makes safety rope belt sliding friction and reach buffer-braking lentamente in the safety rope belt passage; the instantaneous maximum impact force that safety rope belt can be born drops to below the 450kgf; significantly reduced that safety belt has improved the protection effect of safety belt to human body to the shock effect of human body when falling from high altitude.
