Abstract

The utility model discloses a skid-proof chain of a hollow pawl, which belongs to a skid-proof device of bicycles, motorcycle, light vehicles, etc. in the process of walking on ice and snow roads. The utility model is characterized in that a hollow pawl section (2) which is made of thin sheet sheets has skid-proof effect, and the hollow pawl section (2) not only prevents driving slippage but also solves the problem of side skid of a tyre. An integral outline of the utility model is smaller, skid-proof section assemblies which are composed of the hollow pawl section (2) and fixed sheets (4) are dispersed equidistantly and properly on fastening devices, the skid-proof chain can be formed, one or two sections of skid-proof sections are always retained to touch the ground in the process of rolling of the tyre, and the utility model always lies in a skid-proof state. The utility model has the advantages of easy assembly and disassembly, and no influence to normal use of the vehicles; furthermore, a plurality of traffic accidents which are caused by falling down on the snow and ice roads can be avoided to occur, and the utility model can be widely used in northern area of China.

Description

Hollow pawl anti-slipping chain

The utility model relates to a kind of hollow pawl anti-slipping chain, in particular for the hollow pawl anti-slipping chain of bicycle, motor bike.

The snow that ground such as the northern area of China, especially Xinjiang, the Inner Mongol, northeast fell in early winter can keep 3 wheat harvesting periods, causes to people and has inconvenient traffic.Skid on ice snow covered pavement for overcoming full size vehicle, occurred iron chains formula anti-slipping chain at first, solved the anti-skidding problem of Oversize vehicle; Occur many nylon wire shell-type anti-slipping chains in recent years again, solved to the anti-skidding problem of dilly; On TV news, saw the people being arranged last year, do not see popularization so far at the anti-sliding sleeve of manufacturing experimently a kind of non-metallic material for bicycle.

The purpose of this utility model provides a kind of suitable mechanical strength of having of bicycle, motor bike, anti-skidding hollow pawl anti-slipping chain effective, easy to loading and unloading of being applicable to.

For achieving the above object, the hollow pawl anti-slipping chain of the utility model is made up of hollow pawl joint, cylindrical ring, fixed plate and securing device, its hollow pawl joint is made with the book steel disc, and it has two advantages: the first, and it is constant that it scratches the effect of ice face in worn-down process progressively.Because the thickness of its pawl wall is constant when the hollow pawl end of wearing and tearing; The second, the inner chamber of hollow pawl is not afraid of and is full of foreign matter, and foreign matter has the scope of shrinking back all the time when the pawl end lands.Because what lean against is resilient surface of tyre.The skidproof overall package of hollow pawl is by described securing device with going the installation on the wheel.

This securing device can be one by two steel ropes of knotting ring above-mentioned by hollow pawl joint, cylindrical ring, fix last slice anti-skidding joint of forming, resemble the rope ladder pattern and link together.When last wheel is installed this chain is trapped among on the tire two of steel rope with articulating sheet and spring joins.This bindiny mechanism also can bolt together mechanism connect.With some steel wire hooks rubber rope and steel rope are articulated again for preventing that anti-skidding joint string is moving.

This securing device also can be the bandage that two ends have the butt joint eye.The fixed plate at anti-skidding in the present embodiment joint two ends need not boring, but it is curved to roll over the U type, and curved to block the pressing of bandage both sides fastening with this.Last wheel must drain the gas of tire when installing, and the bandage that anti-skidding joint is housed is trapped among on the tire, with the butt joint hook bandage two is articulated, and gets final product to inflation of tire then.

The quantity that the configuration of every cover anti-slipping chain is formed anti-skidding joint by hollow pawl joint, cylindrical ring and fixed plate in the said structure is that the position that lands in the tire rolling process has the anti-skidding joint of 1 joint all the time at least.Make wheel often be in anti-skidding state.

Hollow pawl in this anti-slipping chain so it is very big to the pressure of ice and snow face, is easy to scratch the ice face because it is the wall thickness contact ice and snow face that utilizes hollow pawl, and its antiskid function do not have directivity, and the effect of any direction is all the same.Therefore, thoroughly solved the sideslip problem of bicycle, motor bike, make vehicle can be on the irregular ice snow covered pavement cruising.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1, Fig. 2 are the front view and the cutaway views of hollow pawl anti-slipping chain first embodiment of the utility model.

Fig. 3, Fig. 4 are the front view and the cutaway views of hollow pawl anti-slipping chain second embodiment of the utility model.

Shown in Figure 2ly by 3 cylindrical rings (3) 2 hollow pawls joints and 2 porose fixed plates (4) are connected to one and save anti-skidding joint; Shown in Figure 1, steel rope (8) all wears all anti-skidding joints by the hole of fixed plate (4), is trapped among on the tire (1), and it is fastening steel rope (8) to articulate sheet (5) spring (6), and hook (7) draws rubber rope (9) and rises and articulate in steel rope (8).

Shown in Figure 4, the atresia fixed plate (4) at above-mentioned anti-skidding joint two ends fixes the both sides in bandage (10); The bandage (10) that anti-skidding joint is housed shown in Figure 3 is trapped among on the tire (1), the bandage that anti-skidding joint is housed (10) is articulated by butt joint eye (12) by butt joint hook (11).
