Abstract

The utility model relates to an anti-slip chain, which is provided with a plurality of chains (5) sheathed by steel rings (4), a steel cable (2) and a hook (1) arranged at the end part of the steel cable. The steel rings are parallel, and the steel cable is penetrated in both ends of the chains (5). The utility model is characterized in that the utility model also has an anti-slip block (3), the upper surface and the lower surface of the anti-slip block are respectively provided with 2-3 sharp teeth (9), both ends of the anti-slip block are provided with through holes (8), and the homothetic steel rings of two adjacent chains (5) are respectively penetrated in two through holes (8) in a rotary way. The anti-slip chain is fixed at the outer side of the encircle of a wheel through the steel rope (2), as the sharp teeth (9) are engaged with an ice face and the wheel, the anti-slip force between the anti-slip chain and the ice face is improved, and the anti-slip force between the anti-slip chain and the surface of the wheel is improved.

Description

Nonskid chain

The utility model relates to tire for vehicles, and device relevant with tire or layout particularly can be installed in the anti-skid device on elastic tire or the elastic tyre wheel temporarily.

In China, old-fashioned nonskid chain has used the several years, this nonskid chain is to be arranged in outside the tire along the tire thickness direction by many chain ring type chains (for example lifting chain) to be through in the chain link of end with chain or steel cable on the garden and in the tire both sides, tension chain or steel cable and chain is depended on outside the tire, because being the steel ring in cross section, garden, chain link becomes, so wheel and chain, chain all is the garden cylinder contact of reinforcing bar with contacting of ice face, cylinder is smooth, and is not tight with the interlock of ice face, so friction force is little, skidproof effect is not good, pivot turn takes place in easy yaw behind the old-fashioned nonskid chain on the vehicle band, even produces the accident of car crash.

The purpose of this utility model provides a kind of nonskid chain that can improve anti-skidding power.

The purpose of this utility model realizes by following technical scheme, nonskid chain has the many chains that are nested and are connected into by steel loop that parallel, be through at the steel cable in the steel loop at chain two ends, the hook of steel cable end, it is characterized in that also having nonslipping spur and steel rope, on the nonslipping spur, lower surface respectively has 2-3 bar pointed tooth, two parallel through holes are arranged at the two ends of length direction, rotating respectively being through in one of two through hole of steel loop of two coordinatioies on two adjacent said chains, a hole that is arranged in the nonslipping spur at nonskid chain two ends is installed with said steel rope, and steel cord ends slidably is connected with steel cable.

Nonskid chain of the present utility model, owing to being connected with nonslipping spur, chain forms an integral body, and it is flexible, being placed on wheel also strains with the steel cable at chain two ends outward mutually, it can be invested outside the wheel, because the existence of nonslipping spur, the pointed tooth on its two sides contacts and interlock with wheel and ice face, increase friction force, improved anti-skidding power.

Below in conjunction with drawings and Examples to the detailed explanation of anti-slipping chain row culture of the present utility model.

Fig. 1 is the scheme drawing of the utility model nonskid chain when being loaded on the wheel;

Fig. 2 is the enlarged drawing of A portion among Fig. 1 of the utility model nonskid chain;

Fig. 3 is the scheme drawing that chain link and the ice face of the nonskid chain of prior art contacts with wheel.

As Fig. 1 Fig. 2, this nonskid chain has the chain 5 that is socket-connected and formed by steel loop 4, the arrangement that many isometric chains 5 are equidistant, respectively be installed with a steel cable 2 in the steel loop 4 at its two ends and each chain 5 is connected, the end of steel cable 2 has hook 1, steel cable 2 two ends can be connected, this nonskid chain also has nonslipping spur 3, nonslipping spur 3 can be one certain thickness cuboid, thereon, 2-3 bar pointed tooth 9 is arranged on the lower surface, pointed tooth 9 is preferably along the Width of nonslipping spur, the nonslipping spur two ends have two parallel through hole 8 (see figure 2)s of broad ways, nonslipping spur is between two adjacent chains 5, steel loop 4 rotating being through at respectively in one of two through hole 8 of coordination on the two adjacent chains 5, nonslipping spur 3 is connected with chain 5 and becomes the single-piece of certain-length and width nonskid chain is arranged, this nonskid chain at length direction and width to all flexible, two row's nonslipping spurs 3 at the two ends of nonskid chain, an one through hole 8 is connected with steel loop 4, be installed with steel rope 7 in another through hole 8 each nonslipping spur is connected, the end of steel rope 7 slidably is connected with steel cable 2.

Said steel loop 4 can as lifting chain be oval, steel loop 4 can form with garden steel or bead coil system.

When nonskid chain is made certain length and width by the diameter and the width of different wheel, it is invested wheel garden perimeter surface and steel cable 2 is joined with linking up with 1 in wheel both sides tensions and two ends, then this nonskid chain can be loaded on outside the outer garden of wheel, very convenient, because the pointed tooth 9 and ice face or wheel interlock mutually on nonslipping spur 3 two sides, improved anti-skidding power greatly, and its surface of old-fashioned nonskid chain is the garden cylindricality, cylinder is smooth, not tight with the interlock of ice face, referring to Fig. 2 and Fig. 3, Fig. 2 show this nonskid chain nonslipping spur 3 on, the situation that following pointed tooth 9 and wheel contact with the ice face, wherein f is the static friction force of nonslipping spur and wheel, elastic force making a concerted effort in the horizontal direction, the effect of power f is to make nonslipping spur and wheel that relative motion not take place, power F is nonslipping spur and the friction force of icing face, it makes between nonslipping spur and ice face relative motion does not take place, Fig. 3 shows the situation of old-fashioned nonskid chain, its contact surface is the garden cylindricality, cylinder is smooth, not tight with the interlock of ice face, wherein f ＇ is the static friction force of contact surface and wheel, elastic force making a concerted effort in the horizontal direction, F ＇ is contact surface and the friction force of icing face, as mentioned above, obviously f ＇ is less than f, F ＇ is less than F, so nonskid chain of the present utility model can improve wheel and nonskid chain, and the anti-skidding power between nonskid chain and the ice face.Our experiments show that, use this nonskid chain, automobile is glancing impact on the ice face, and phenomenons such as pivot turn, yaw do not take place.
