The spring handgrip for the bus comprises a composite spring of which the upper end is fixed on a horizontal handrail of the bus, and an elastic hanging ring connected at the lower end of the spring, wherein the composite spring comprises an alloy spring; the alloy spring is coated with an elastic gutta percha composite layer through casting moulding to form a composite spring body; the elastic hanging ring is made of at least one of plastic or rubber. The spring handgrip for the bus has excellent damping effect, can withstand load and a relatively large amount of deformation, and is stable in vibratory mechanical property, safe to use and long in service life.
Description
Technical field
The present invention relates to a kind of bus composition accessory, particularly relate to a kind of bus spring handle.
Background technology
Bus handle is requisite composition accessory on bus.In the prior art, bus handle is generally designed to following structure: upper end is fixed on to be held up on bar, centre is the soft band of a connection, soft band lower end connects hard suspension ring, in use there is following defect in the handle of this structure: bus stops, start, in the processes such as turning, hold the hand of suspension ring just taking attachment point as the center of circle, drawing swinging of soft band in a circular conical surface, the spatial dimension of motion is larger, the balance of health is destroyed, reliable property is poor, be easy to cause the wiping between mutual collision and passenger and the car body between passenger to hang, cause passenger's body to come to harm, and the impulse force that health rocks suddenly generation causes hand firmly larger, likely causes wrist injured, in addition, existing suspension ring generally adopt rigid plastic to make, and quality is harder, while pulling the overlong time of suspension ring, are easy to feel to ache.
Summary of the invention
There is the defect of potential safety hazard for overcoming prior art, the invention provides that a kind of damping is good, vibrating machine stable performance, shake hands safety bus spring handle comfortable.
Technical matters solved by the invention can adopt following technical scheme to realize:
A kind of bus spring handle, comprises that upper end is fixed on the elasticity suspension ring that bus level is held up the complex spring on bar and is connected to spring lower end.
Preferably, described complex spring comprises alloy spring, and described alloy spring is outer is enclosed with elasticity gutta-percha composite bed formation complex spring body by the method for moulding by casting.
Preferably, described complex spring is fixed on level by steel rope or screw and holds up on bar.
Preferably, by plastics or rubber, at least one makes described elasticity suspension ring.
Preferably, described alloy spring forms by the Raw material processing of following component and proportioning: C:0.3500～0.7000%, Si:0.8000～4.5200%, Mn:0.1600～2.200%, P:0.003～0.0800%, S:0.003～0.0800%, Cr:0.7000～3.8000%, Sc:0.0015～0.0600%, Al:0.0005～0.0500%, N:0.0020～0.0100%, surplus is Fe and inevitable impurity.
Preferably, described elasticity gutta-percha is made by following component and proportioning: gutta-percha 15-95 part, rubber additive 5-85 part, sulphur 3-7 part, sulfur containing promoter 1-5 part, ZnO1-5 part, CaO1-5 part, resin improved agent 1-11 part, carbon black 30-80 part, aging inhibitor 2-4 part.
Preferably, described elasticity gutta-percha composite bed also comprises in poly-urethane rubber, butadiene rubber, viton, EP rubbers, butyl rubber and natural rubber one or more.
Compared with prior art, the beneficial effect that the present invention has is: complex spring is replaced to soft band, good springiness, retraction force are strong, there is good buffer capacity, bus, in the time rocking, can make the hand of holding suspension ring move in less space, thereby health can keep balance preferably, good stability, has eliminated the potential safety hazard that uses draw ring.Elasticity suspension ring quality is soft, pulls suspension ring pleasant.
Detailed description of the invention
Below in conjunction with detailed description of the invention, technical side of the present invention is understood, below in conjunction with detailed description of the invention, further sets forth invention:
A kind of bus spring handle, comprises that upper end is fixed on the elasticity suspension ring that bus level is held up the complex spring on bar and is connected to spring lower end.Complex spring is around to wrap up the sulfuration of elasticity gutta-percha composite bed by metal coil spring to form, and complex spring is replaced to soft band, and good springiness, retraction force are strong, not out of shape when carrying, has good buffer capacity.Because good springiness, the retraction force of complex spring is strong, load performance is stable, in the time that bus rocks, pull suspension ring, draw the hand of suspension ring in less spatial dimension motion, thereby make health held stationary preferably, can not cause collision and wipe and hang, can not injure wrist yet, having eliminated the potential safety hazard that uses handle.Suspension ring are made with elastomeric material, can increase the traveling comfort that pulls draw ring, and long-time draw ring can not felt hand acid.
Complex spring can be composited by alloy spring and elasticity gutta-percha, and the outside that elasticity gutta-percha is wrapped in alloy spring by the method for moulding by casting forms composite bed.Alloy spring can form by the Raw material processing of following component and proportioning: C:0.3500～0.7000%, Si:0.8000～4.5200%, Mn:0.1600～2.200%, P:0.003～0.0800%, S:0.003～0.0800%, Cr:0.7000～3.8000%, Sc:0.0015～0.0600%, Al:0.0005～0.0500%, N:0.0020～0.0100%, surplus is Fe and inevitable impurity.It is strong that this alloy spring intensity is high, toughness strong, bullet subtracts drag, is adapted at normally working under load environment, and has the longer life-span.The elasticity gutta-percha that is wrapped in alloy spring outside is made by following component and proportioning: gutta-percha gutta-percha 15-95 part, rubber additive 5-85 part, sulphur 3-7 part, sulfur containing promoter 1-5 part, ZnO1-5 part, CaO1-5 part, resin improved agent 1-11 part, carbon black 30-80 part, aging inhibitor 2-4 part.This elasticity gutta-percha is amorphism network Polymer, belongs to rubbery material, and elasticity is very strong, and has good dynamic tensile fatigue property, high Stress at definite elongation.During with elasticity gutta-percha parcel alloy spring, if alloy spring fracture, elasticity gutta-percha also plays carrying effect, can not have an accident at once.
The elasticity gutta-percha composite bed of complex spring is made up of elasticity gutta-percha, also can comprise one or more in poly-urethane rubber, butadiene rubber, viton, EP rubbers, butyl rubber and natural rubber.
