CN2130142Y - Ball surface foot anti-slip chain - Google Patents

Abstract

The utility model relates to a ball surface foot anti-slip chain which is suitable for various vehicles with rubber tyre such as automobiles and tractors, belonging to a transportation means. The utility model comprises a transverse chain, side chains and a spring tension apparatus. The utility model is characterized in that the transverse chain comprises an anti-slip ring with a ball surface foot, a connective ring, and a connective hook, at the same time, the spring tension apparatus which has hooks on both ends is adopted to tension the side chains, so the complete set of the anti-slip chain can be tighten on the tyre. Compared with the existing anti-slip chain, the utility model can give the guarantee to vehicles driven on various slide roads, having the advantages of reliable anti-slip performance, non-perishable loosening, non-perishable fracture, low noise, easy assembly and easy disassembly.

Description

Ball surface foot anti-slip chain

The utility model belongs to transportation means.Being suitable for being equipped with various vehicles such as the automobile of rubber tire and trac. uses.

Existing anti-slipping chain is made of twisted shape cross chain and side chain.When mounting, install around anti-slipping chain around the wheel tyre after, in the outside of wheel, side chain is drawn tighten with the rope made of hemp.For a long time, exist following point and shortcoming in the use: when sliding driving on snow-icing road, friction force is not enough, and antiskid capability is poor, can not normal brake application, and it is severe, dangerous down grade to break away, the difficulty of going up a slope.When meeting unexpected situation, have an accident often owing to can not slow down rapidly.Simultaneously, in the driving, anti-slipping chain is easily loosening, easy fracture, and whipping is big, and noise is big.

The purpose of this utility model is to solve the problems referred to above and the shortcoming that existing anti-slipping chain in use exists, and provides a kind of antiskid capability reliable, new-type antiskid instrument easy to use.

Describe realization the technical solution of the utility model and particular content in detail below in conjunction with accompanying drawing.

Fig. 1 is that the utility model mounts total figure on wheel.

Fig. 2 is an expansion drawing of the present utility model.

Realize that the technical solution of the utility model is to adopt the combination cross chain (8) that is made of the anti-slip ring (5) of rectangle, coupling link (6) and the butt hook (7) that have sphere nail pin, replaces original twisted shape cross chain.This is a principal character of the present utility model.Simultaneously, set up the spring tensioning means (4) of a kind of two ends band hook,, replace drawing with the rope made of hemp originally tying up side chain in order to tension side chain (9).This is another feature of the present utility model.

Particular content is as follows:

Generally, by the mutual alignment and the assembly relation of each part shown in Figure 2, two the anti-slip ring (5) of rectangle, three coupling links (6) and two butt hooks (7) that have sphere nail pin are formed a combination cross chain (8); Seven regulating rings (1), 48 long rings (3) and a hook (2) that has anti-flake spring are formed a combination side chain (9); Again 13 cross chains (8) are connected with two side chains (9), just are assembled into a sphere pin anti-slipping chain that wheel is used.Two anti-slipping chains are called a cover.

In particular cases, can suitably prevent the number of slip ring (5) and coupling link (6) and the number that makes up the middle long ring of side chain (9) (3) in the bar number of increase or minimizing combination cross chain (8), the combination cross chain according to diameter of tyres, width size and actual needs.

During use, the sphere of anti-slipping chain nail pin towards the road surface, is launched the shop on the way with anti-slipping chain, car is left up.Then, anti-slipping chain around wheel tyre, is suspended to the hook (2) of two side chain (9) one ends on the regulating ring (1) of other end appropriate location.By shown in Figure 1, three spring tensioning means (4) are suspended on the side chain (9) of lateral wheel again.Promptly finished the work that mounts of a tire chain.By the work that mounts of finishing the opposite side tire chain with quadrat method again.

When vehicle walks to the somewhere, because the road surface is too sliding, drive forward and reversing back when all dangerous, when perhaps tyre skidding can not travel, the also available mode of putting on a suit of armour mounted anti-slipping chain.Because spring tensioning means has retractility, still can make sphere pin anti-slipping chain give play to good antiskid capability.Thereby, make vehicle hightail danger and predicament, continue cruising.

The utility model is compared with existing anti-slipping chain, has outstanding, failure-free antiskid capability.Can not only guarantee vehicle safety traffic on the very sliding various standard highways in road surface, and under steam this kind sphere pin anti-slipping chain be difficult for loosening, easy fracture not, noise is little.Load and unload convenient and time-saving again.

Claims (2)

1, a kind of sphere pin anti-slipping chain of being made up of cross chain (8), side chain (9) and spring tensioning means (4) is characterized in that described cross chain (8) is made of the anti-slip ring (5) of rectangle, coupling link (6) and the butt hook (7) that have sphere nail pin.

2, the described spring tensioning means of claim 1 (4) is characterized in that at the two ends of extension spring a hook being housed respectively.
