Abstract

The utility model relates to an automotive non-skid chain, which is cramped on vehicle tyres by an antislip strip, a connecting bar and a radial fastening device connecting with each other. The antislip strip connecting with the connecting bar form the bottom, and the public chain is a double trapezoid mesh shape of the top margin. The antislip strip has strong antiskid property, dispersive frictional force and good fastening character. The utility model also has the advantages of light body, easy installation, low cost, simple structure, small wave and long service life, etc., which is suitable for large, medium, small cars and motor vehicles running in the snow and ice weather.

Description

Automotive non-skid chain

The utility model belongs to the annex manufacturing of automobile, is a kind of anti-slipping chain that automobile is used specifically.

In order to prevent motor tire from skidding have an accident during ice and snow weather running car winter, on the active tire anti-slipping chain is housed.At present anti-slipping chain has three kinds of chain formula, plastics crawler type and steel rope ball-types: chain formula connection mode is the parallel vertical ladder shape, and the bonded assembly spacing is little too heavy, and the big skidproof effect of bonded assembly spacing is poor.The plastics crawler type can only be used on the dolly, and its skidproof effect is poor, and service life is short.And the connection mode of steel rope ball-type is the same with the chain formula, and can only be used on the dolly.

In order to overcome above-mentioned shortcoming, the utility model provides that a kind of body is light, easy for installation, the top ripple is little, resistance to wears, the Automotive lock chain type anti-slipping chain of good antiskid effect and long service life.

The utility model is achieved in that it is formed by connecting by tread plate, connection bar and securing device.Tread plate and connection bar are formed by connecting by disciform chain link.It is that the end, public chain are that the double trapezoid of top margin is netted that tread plate connects into according to connecting bar.The circumferential bindiny mechanism that connects bar is that an end link is connected with annulus, connects bar other end chain link and is connected with an end of hook ring stand, and the hook ring stand other end is connected with the hole of the stub end of S type hook, is with the hook lock ring on the hook ring stand, and the hook lock ring has an opening.The annulus that connects bar one end is inserted in the hook of S type hook stub end, rotates S type hook its little head end is entered in the hook shackle openings on the hook rack, and the hook look ring set advances the S type to be linked up with in the hook of little head end, like this anti-slipping chain is connected to a cast.

Radial tightening device is made up of steel ring and extension spring thereon.The other end of several springs hangs on the connection bar of anti-slipping chain uniformly along the steel ring circumference, and anti-slipping chain is strained.

Because tread plate of the present utility model adopts the netted connection of double trapezoid, it is strong to make it antiskid capability, and friction force disperses, and tightness is good.Adopted eccentric S type hook structure owing to connect the connection of bar, made the circumferential connection of anti-slipping chain simple and reliable.Radial tightening device makes it existing rigidity owing to adopt the connection structure of steel ring and spring, and is flexible again.The utility model has also that body is light, easy for installation, cost is low, simple in structure, the top ripple is little and advantage such as long service life, it is suitable for large, medium and small type automobile and self-propelled vehicle in the ice and snow weather anti-skidding usefulness of travelling.

Fig. 1 is tread plate of the present utility model and the structural representation that connects bar, tread plate 1, connection bar 2, S type hook 3, hook ring stand 4, hook lock ring 5 and annulus 6.

Fig. 2 is 3,4, the 5 connection structure birds-eye vieies of Fig. 1.

Fig. 3 is for connecting the connection structure scheme drawing of bar.

Fig. 4 is the utility model running condition scheme drawing, spring 7, steel ring 8 and motor tire 9.

As shown in Figure 1 (is example with Beijing 130 type automobiles) to make endoporus wide by round steel be 7 millimeters, length is 18.5 millimeters ellipse chain link, chain link connects into 8 rings and 5 chains that encircle.Chain connects into the tread plate 1 that top margin is the double trapezoid reticulate body of common edge, and trapezoidal base and waist limit are 8 loop chain bars, and public top margin is 5 loop chain bars, connects with annulus between each chain, and the diameter of bore of annulus is 13 millimeters.The base of 8 groups of double trapezoid reticulate bodies is linked together with the chain of 5 rings respectively, and the base chain is formed with the chain that is connected them and is connected bar 2.The two ends connection structure that connects bar is that an end is connected with annulus 6, and the other end is connected with an end of hook ring stand 4, and the other end of hook ring stand 4 is connected with the hole that the S type is linked up with 3 stub ends, is with the hook lock ring 5 of middle opening on the hook ring stand 4.

As shown in Figure 3, radial tightening device of the present utility model is to make steel ring 8 by round steel, and the internal diameter of steel ring 8 is 25 millimeters.Steel ring 8 hangs with 5 springs 7, and the diameter of spring is that 13 millimeters, length are 100 millimeters, and the diameter of spring wire is 1 millimeter.

Above-mentioned chain link, annulus, hook ring stand 4, hook lock ring 5, steel ring 8 are that 5 millimeters A3 round steel is made by diameter, S type hook by thick be that 3 millimeters A3 steel plate is made.

As shown in Figure 3, Figure 4, tread plate 1 and connection bar 2 bonded assembly anti-slipping chains are centered around on the motor tire 9, the annulus 6 that connects bar 2 one ends is inserted in the stub end hook of other end S type hook 3, rotating S type hook 3 makes little head end enter hook lock ring 5 central closings, and hook lock ring 5 packs into the S type and links up with in the hook of 3 little head ends, and anti-slipping chain is circumferentially strained.Along on the circumferentially uniform connection bar 2 that hangs over anti-slipping chain, anti-slipping chain is radially strained at 5 springs on the outside of tire 9 steel ring 8.

Claims
