Abstract
The utility model discloses a kind of ribbon lead ring, comprise a conduit, described conduit carries out 180 ° of bendings at 2 trisection point places to same direction, at 2 six Along ent places near end of conduit then towards opposite sense 90 ° bending, forms criss-cross.The whole ribbon lead ring of the utility model is designed to criss-cross, and make ribbon lead ring have orthogonal two passages by 2 bendings, when belt-strap because when External Force Acting slides, the instantaneous binding force produced, far above traditional ribbon lead ring, prevents the too fast potential safety hazard brought because belt-strap slides further.
Description
Technical field
The utility model belongs to vehicular spare parts field, is specifically related to a kind of ribbon lead ring.
Background technology
In vehicular spare parts field, belt-strap is very important security implementations, and the technology therefore relating to belt-strap is the research and development problem of technical personnel in field always.Ribbon lead ring guide is used to the part changing ribbon direction, is convenient to the layout of Webbing retractor, makes safety strap be close to occupant, effectively occupant restraint body movement, improves the traveling comfort that occupant wears safety strap.But because ribbon is producing sliding resistance by flexural deformation during guide, requiring that guide surface is smooth, friction coefficient is little, arc surface curvature is moderate, reducing the distortion of ribbon when sliding and resistance.The slidingsurface of ribbon lead ring has smooth chrome-plated surface, inserted smooth metal ring surface.The arc surface contacted with ribbon due to the guide of embedded with metal ring is large, and therefore when ribbon pull-out and backrush, resistance is little.
At present, the Technical comparing of belt-strap is ripe, adopts highdensity material to get at and reaches requirement, but as effector's ribbon lead ring of belt-strap, current structure still has larger room for improvement.The structure of what ribbon lead ring was general still adopt square Intermediate Gray horizontal stripe; but along with belt-strap thinness is more and more less; the binding force of this structure but can not be met; belt-strap ratio is easier to regard to landing out of reach constraint effect; in addition safety strap tightening device generally adopts gas to produce the mode of blast; the air pressure utilizing gas to produce instantaneously promotes the motion of the pipeline amount of doing body; reach spinning reel; the pull-out resistance of regulation is applied on spool; thus safety strap is in the tension state of regulation, reach the object of protection passenger.Its installing space occupied is comparatively large, and the processing technology of tightening system and parts is complicated, and cost is high, and it adopts plastics to be raw MAT'L, easily weares and teares, intensity is low, poor safety performance in use procedure.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of ribbon lead ring controlling belt-strap and rise and fall.
Technical scheme: in order to reach foregoing invention object, the utility model has specifically come like this: a kind of ribbon lead ring, comprise a conduit, described conduit carries out 180 ° of bendings at 2 trisection point places to same direction, at 2 six Along ent places near end of conduit then towards opposite sense 90 ° bending, form criss-cross.
Wherein, gap is had during described conduit two ends bending.
Wherein, described end of conduit is hook-shaped.
Wherein, after described conduit bending, distance is 0.5 ~ 0.8cm between the upper and lower.
Wherein, the material of described conduit is 45# steel or S550MC.
Wherein, the diameter of described conduit is 0.2 ~ 0.5cm.
Beneficial effect: the utility model, compared with conventional art, has the following advantages:
1, whole ribbon lead ring is designed to criss-cross, and make ribbon lead ring have orthogonal two passages by 2 bendings, when belt-strap because when External Force Acting slides, the instantaneous binding force produced, far above traditional ribbon lead ring, prevents the too fast potential safety hazard brought because belt-strap slides further;
2, the plastic material that intensity is low makes the round steel material of high strength into, and smooth surface, friction coefficient are little, and utilizes the punching press of grinding tool technology, and its intensity is increased, stability improve and reduce costs, compact conformation.；
3, primarily of framework, mandrel, end cap and driving device composition, the mandrel being tied with safety strap is provided with the torsion head of tooth, outside suit transmission gear, plays after being at utmost wound around and can discharge ultimate range, increase safety effect power;
4, a trundle is set at each circular arc corner position, is positioned by retainer, do not contact with torsion head, serve the effect improving backrush power;
Accompanying drawing explanation
Fig. 1 is back view of the present utility model;
Fig. 2 is lateral plan of the present utility model.
Detailed description of the invention
A kind of ribbon lead ring as shown in Fig. 1 ~ 2, comprises a conduit, and described conduit carries out 180 ° of bendings at 2 trisection point places to same direction, at 2 six Along ent places near end of conduit then towards opposite sense 90 ° bending, forms criss-cross; Have gap during described conduit two ends bending, end of conduit is hook-shaped; After described conduit bending, distance is 0.5 ~ 0.8cm between the upper and lower; The material of conduit is 45# steel or S550MC; The diameter of described conduit is 0.2 ~ 0.5cm.
