Abstract
The utility model relates to anti-skid technology for bicycles, particularly to an anti-skid chain for bicycles. The strip cambered surface points of every chain link cambered bodies are provided with anti-skid teeth, and both side elastic plates which are formed by the downward and transverse extension of the cambered surface points are provided with round holes on the bending points of the elastic plates and bosses on the end parts of the elastic plates. Bicycle riders are not easy to slip and hurt when running on snow and ice road surfaces due to the appearance of the utility model; therefore, the utility model is convenient for the bicycle riders when the bicycle riders walk out on the snow and ice road surfaces in winter. The utility model has the advantages of simple and reasonable structure, easy processing, easy integral installation, and good anti-skid property.
Description
The utility model relates to the anti-slip technology of bicycle, specifically the cross-track tyre chain of bicycle.
At Chinese north of china in winter, after the sleety weather,, skid when causing people and travelled by vehicle and travel difficultly if can not in time remove can road surface slippery for ice and snow on road surfaces, advancing especially by bike can be easy to cause bicycle to slip and make toy horse-riding bicycle people tumble injury.How to prevent that bicycle from skidding is the problem that relevant department paid close attention to always.
The utility model is the problem at above-mentioned existence, provides a kind of simple in structure, is easy to install and use the antiskid bicycle chain of good antiskid effect.
The utility model is that a plurality of chain links are connected to each other formation, and the strip cambered surface place of each chain link arc body is provided with anti-slop serrations, and cambered surface place downward horizontal expansion two-side elastic plate is provided with the circular hole that turns the place and the boss of end.The anti-slop serrations that the strip cambered surface place of each chain link arc body is provided with is 2～6; Circular hole on the elastic plate and boss separately the garden diameter at place less than diameter of tyres.
Appearance of the present utility model is difficult for causing when by bike people is travelled on ice and snow road slips and tumble injury, brings convenience when giving the trip of cyclist's ice and snow road in winter.Its each chain link simple and reasonable for structure, easy to process be easy to integral installation, and antiskid capability is good, easy to utilize.
Description of drawings:
Fig. 1 is a contour structures scheme drawing of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
Fig. 4 is that the C of Fig. 1 is to view.
The given chain link of the utility model is to be made by a steel integral body, relies on the elasticity of steel to guarantee to connect reliable, can not come off a plurality of chain links formation anti-slipping chain that connects together mutually voluntarily.During assembling, boss 1 inserts in the circular hole 3 of an adjacent chain link, and elastic plate 2 dependence self elastic force stably is inserted in boss in the circular hole laterally, can not get loose.The transversal surface rigidity of arc body is bigger, be out of shape less, so that guarantee can be because of repeatedly stressed fatigue fracture.Anti-slop serrations is anti-skidding usefulness, improves hardness through bakingout process and increases wear resisting property, and after installing, the circular diameter at boss and circular hole place should be less than 4～6 centimetres of tire maximum gauges, can guarantee effectively that anti-slipping chain is unlikely to break away from tire because of external force.
From Fig. 4 as seen, this chain link is L-shaped; Its boss 1 is two kinds with the distance A of circular hole 3, a kind of is the main chain joint, a kind of is to regulate chain link, regulating chain link is the A value 2mm of A value less than the main chain joint, the some adjusting chain links of optional equipment in every cover anti-slipping chain, adapting to tire circumference variation among a small circle, and tire circumference variation in a big way can be adjusted by the quantity of increase and decrease main chain joint, according to tire circumference increase and decrease anti-slipping chain length.The installation of this anti-slipping chain only need free-handly save two boss with shot and inwardly compress in the circular hole that can insert another joint, also circular hole firmly can be pressed into boss, can after also can organizing a chain earlier, installation on the bike tyre be entangled on the tire, one joint or number joint are installed at last, and final section is strained to reduce the gap between antiskid bicycle chain and tire as far as possible.Pin one sled is taken a side apart in the boss that is inserted in arbitrary joint with special-purpose small tools during dismounting and the circular hole, takes opposite side equally again apart, promptly breaks a joint, and can whole pull down anti-slipping chain (this moment need rotating-wheel).
Said boss 1 is to be stamped to form, and elastic plate 2 is to become the shape that approaches to form better elastic the steel punching out, is used for installing/dismounting.Circular hole 3 and anti-slop serrations 4 are punching out.
