Abstract
The utility model relates to an antiskid device which is particularly suitable for the antiskid property of bicycle tyres. The antiskid device comprises a metal antiskid band and fixed clamps, wherein antiskid convex teeth formed by punching flanges or punching and stretching are arranged on the metal antiskid band, and the antiskid convex teeth are in sequential arrangement according to rules such as uniformity, symmetry, equidistance, parallelism, interlacing, etc.; the fixed clamps are horseshoe-shaped spring clamps with flat heads. The metal antiskid band is clamped on a tyre through a plurality of fixed clamps arranged at intervals and at ends. The antiskid device has the advantages of simple structure, low manufacturing cost, easy assembly and disassembly, convenient use and good antiskid property.
Description
The utility model relates to a kind of anti-skid device, particularly is applicable to the anti-skidding of bike tyre.
Existing anti-skid device has structures such as metal chain, plastics class, and the former easy road pavement and tire cause damage, and noise is big in using.The latter lacks service life, antiskid capability is poor.And aforementioned two class anti-skid devices mainly are at vehicle skidproof design, do not see gratifying anti-skid device as yet to bike tyre is anti-skidding.
The purpose of this utility model provides a kind of bicycle antiskid device, can effectively grab ice and snow road by the anti-skidding protruding tooth that distributes on this device metal skidring, significantly improves the skidproof effect in travelling.
The purpose of this utility model can be achieved through the following technical solutions: a kind of anti-skid device, form by comprising metal skidring and fixed card, its special character is, has anti-skidding protruding tooth on the described metal skidring through punching press flange or certain altitude that punching stretch forms, anti-skidding protruding tooth is arranged by certain rule ordering, fixed card is a tack shape of a hoof Spring Card, the metal skidring by several betwixt every with end points on the fixed card that is provided be installed on the tire.
Advantage of the present utility model is: when anti-skidding, because the anti-skidding protruding toilet article that are distributed on the metal skidring have the good holding power that opens ice, so have significant skidproof effect during driving; And,, satisfy the skid-resistance requirements of various performances so it can obtain the forward and the anti-skidding power of side direction of different sizes because the arrangement of anti-skidding protruding tooth on the metal skidring can be designed to different α angles, possess good forward and side direction skidproof effect; Because fixed card is designed to the tack horseshoe-shaped structure,, this fixed card finishes rational assembling so combining metal skidring and tire satisfactoryly; Metal skidring and fixed card reduce its weight simply greatly because compact conformation is gone up in design, so do not feel that driving difficultly pedals double infection.

Fig. 7 for fixed card the assembly scheme drawing that metal skidring and tire are combined and installed together, the terminal bayonet socket 6 that gives expression to fixed card among the figure is eventually extremely in the outer rim of wheel steel ring 9 and do not contact with it;
Being described as follows of each label among the above-mentioned figure:
1 is the metal skidring, 2 is anti-skidding protruding tooth, 3 is the hole, space that forms behind the punching press flange, and 4 is fixed card, and 5 is the tack position of fixed card, 6 is the terminal bayonet socket of fixed card, 7 is the cross section of inflation of tire part, and 8 is tire, and 9 is the wheel steel ring, α is the angle that anti-skidding protruding tooth is arranged on the metal skidring, and β is anti-skidding protruding tooth when punching press flange or punching stretch form and the vertical angle of metal skidring.
Be described in detail embodiment of the present utility model in conjunction with the accompanying drawings:
Anti-skidding protruding tooth 2 on the metal skidring 1 is distributed on the metal skidring 1 by regular serial arrangement such as even, symmetrical, equidistant, parallel, staggered, anti-skidding protruding tooth 2 the angle [alpha] of arranging on the metal skidring 1 between 0 ° to 180 °, choose and with 30 ° with 45 ° for commonly used and best, α among Fig. 1 is 90 °, and the α among Fig. 3 is 30 ° and 90 °.Anti-skidding protruding tooth 2 when punching press flange or punching stretch form with the vertical angle β of metal skidring 1 70 ° with 110 ° between choose and become 90 ° to be the best with vertical, the β among Fig. 2 is 90 °.The height of each anti-skidding protruding tooth 2 should be consistent, highly generally get 1.5 to 5mm for best, the interval of anti-skidding protruding tooth 2 is generally 5 to 50mm, its big or small at interval should matching with the fixed card 4 of being joined, it should guarantee to hold equipped mutually with it fixed card 4(at interval at least and see Fig. 5).Anti-skidding protruding tooth 2 on the metal skidring 1 can be positioned at the both sides portion (see figure 1) of metal skidring 1, also can be positioned at the middle part (see figure 3) of metal skidring 1, also can be distributed in the both sides portion and the medium position of metal skidring 1 simultaneously.Metal skidring 1 adopts common iron to get final product, and more suitable with the spring steel, its width is generally 10 to 50mm, and thickness is generally 0.5 to 2mm.The length of metal skidring 1 equates with tire circumference or slightly is shorter than girth 1 to 20mm.
