Abstract

The utility model relates to a wheel rim with an improved steel wire fixing structure. The utility model is characterized in that two fastening parts at both sides of the wheel rim respectively extend toward outside and are provided with fixing parts; the fixing parts are penetrated with circular holes respectively toward the direction of a wheel hub for penetrating and fixing a copper head and a steel wire; the bottom part of the wheel rim is provided with a connecting part with two inclined planes toward the direction of the wheel hub. When the wheel rim rotates, the state of stable running can be achieved through the balancing tension of the fixing parts at both sides of the wheel rim; the utility model has the advantages that the completeness of the wheel rim can be kept, the strength of the structure can be intensified, and the service life of the wheel rim can be prolonged. The utility model can not only be used in various tyres with inner tubes, but also can provide the installation of tyres without inner tubes, and the application range of the utility model can be widened.

Description

The wheel rim of fixation with steel wire structural improvement

The utility model is relevant for bicycle, particularly about the wheel rim of bicycle.

Press, the fixation with steel wire structure of non-power-driven vehicle wheel rims such as Regular Bicycle, three-wheel vehicle usually as shown in Figure 1, 2, 3 at present, tie up to and near the line of centers of wheel rim 1, be equipped with several circular holes 10 in regular turn, then copperhead B one end is fixed in the circular hole 10, lie in the copperhead B other end and be installed with steel wire A, again steel wire A is fixed in wheel hub C place, and it is fixing to be accomplished the wheel rim steel wire.Only these structures owing to steel wire A system is fixed by the monolateral wheel hub C that pulls to of wheel rim 1, therefore when the vehicle ' wheel rim rotates, cause the pulling force overbalance easily, and make intensity reduce, thereby damage easily, initiating failure.And be equipped with circular hole 10 on the wheel rim 1, and in a single day therefore can't use the tire of inner tube free, otherwise use the tire of inner tube free, then air pressure easily leaks from circular hole 10, and has limited the scope that tire is selected for use.And be equipped with circular hole 10, also weakened the structure of wheel rim 1, and easy depressed deformation.Therefore, because the structure of known wheel rim steel wire is used ideal not to the utmost, the design people considers to be improved, and through the test of many times test, is initiated the utility model then.

The purpose of the utility model can reach balance and stability when being to provide a kind of rotation, and strengthens structural strength, and applicable to the wheel rim of the fixation with steel wire structural improvement of tubeless tires installation.

The purpose of this utility model is achieved in that

A kind of wheel rim of fixation with steel wire structural improvement comprises both sides and has to the rounded wheel rim of the blocking part of outer lug, it is characterized in that: this two blocking part is extended with fixed part to its outside respectively, is equipped with circular hole to the wheel hub direction respectively on this two fixed part.

Above-mentioned wheel rim fixation with steel wire structural improvement is characterized in that: end extends to the wheel hub direction respectively a connecting portion with two dip plane is set outside this two fixed part.

Above-mentioned wheel rim fixation with steel wire structural improvement is characterized in that: this two blocking part extends to the wheel hub direction respectively a connecting portion with two dip plane is set.

The utility model has following advantage really:

1. the wheel rim both sides are provided with fixed part, and this fixed part is provided with circular hole, can wear for steel wire and copperhead, therefore when wheel rim rotates, can produce the even pulling force of balance, and left and right sides deflection arbitrarily not, can improve the degree of stability of bicycle running.

2. do not wear any circular hole on the body part of circle, therefore can be by the tire of dress inner tube free, and the situation that does not have a pressure leakage takes place, thus can increase the practicality of wheel rim.

3. the body of wheel rim does not wear circular hole, can keep the integraty of rim body, therefore can strengthen the intensity of structure own, has set up again to be the leg-of-mutton connecting portion of sealing, can bear bigger pressure and pulling force, do not damage easily, and can life-saving.

4. the utility model is applicable to the wheel rim of any section form, so applicability is extensive, and can be fit to various bicycles (as cross-country car, mountain-climbing car) use.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.

Fig. 1 is that the circular hole of known wheel rim is provided with scheme drawing.

Fig. 2 is known wheel rim fixation with steel wire cutaway view.

Fig. 3 is known wheel rim fixation with steel wire scheme drawing.

Fig. 4 is that the circular hole of the utility model is provided with scheme drawing.

Fig. 5 is a kind of example structure cutaway view of the utility model.

Fig. 6 is structure shown in Figure 5 and fixation with steel wire scheme drawing.

Fig. 7 is another example structure cutaway view of the utility model.

At first, see also shown in 4,5,6, the utility model mainly is provided with both sides to have to the rounded wheel rim 2 of the blocking part 21 of outer lug.This blocking part 21 is the usefulness for mounting of tyre.Two blocking parts 21 have protruded out fixed part 22 to its outside respectively, and the connecting portion 20 that a tool two dip plane are set is extended to wheel hub C direction respectively in these two fixed parts, 22 outer ends.Offer circular hole 23 to wheel hub C direction respectively on this two fixed part 22; This circular hole 23 and penetrate the dip plane of connecting portion 20.

Another kind of embodiment of the present utility model as shown in Figure 7, connecting portion 20 is to be formed to wheel hub C direction diagonally extending by wheel rim 2 both sides blocking parts 21 in this embodiment.Two fixed parts 22 are the cantilever-shaped side outside two blocking parts 22 that splits.Circular hole 23 is separately positioned on this two fixed part 22.

During assembling, the copperhead B top that will be connected with steel wire A penetrates respectively in the circular hole 23 of wheel rim 2 both sides fixed parts 22, but it is inner and can not become flexible arbitrarily to make copperhead B embedding be butted on circular hole 23, steel wire A is fixed in wheel hub C place again and is strained and fixed it.Tire D is installed on the blocking part 21 of wheel rim 2 then, finishes and can assemble.When bicycle running, when wheel rim 2 affords downward pulling force, and but wheel rim 2 nationalitys see through steel wire A by two side fixed parts 22 and on average transmit strength and absorb to wheel hub C place, because wheel rim 2 two sides rely on the stay bolt that steel wire A is arranged, left and right deflection when therefore wheel rim 2 moves in turn, and can reach best state of equilibrium.Do not establish any circular hole in wheel rim 2 bodies again, so after the tire D of installation inner tube free got on, then pressure can not leaked by the circular hole place.Therefore the utility model decapacitation is installed generally has outside the tire of the inner tube of a tyre, and the tubeless tires D of each style can also be installed, thereby increases practicality.In addition do not have circular hole 23 in wheel rim 2 bodies, the bottom is provided with section connecting portion triangular in shape 20 again, has therefore both kept the integraty of rim structure, the structural strength of enhancing itself again, and can bear bigger pressure and pulling force, to increase the service life.
