Abstract
The purpose of this utility model is to provide a kind of dust-proof lug nut, comprise spanner auxiliary section and compressed part, and the tapped hole to match with the screw thread on corresponding screw rod, described spanner auxiliary section and the fixed connection of described compressed part, described compressed part has a smooth seal face, described tapped hole is blind hole, the opening of this blind hole is positioned on described seal face, described seal face is also provided with around described opening and the bulge loop coaxial with described tapped hole, the internal surface of described bulge loop is inner cylindrical surface, the diameter of this inner cylindrical surface is equal to or greater than the large footpath of described tapped hole, the outer surface of described bulge loop is conical surface.Because the tapped hole coordinated with screw rod is blind hole, the end of assembling rear screw rod can be avoided to be exposed to the external world; Simultaneously due to the compressed part of lug nut having smooth seal face, dust is difficult to the rotatingshaft entering tire from the cooperation position of lug nut and wheel hub, makes lug nut have dust reduction capability.
Description
Technical field
The utility model relates to a kind of fastening accessory of automobile tire, especially a kind of dust-proof lug nut for locking automobile tire.
Background technique
Lug nut is used to the specialized nut of the wheel hub on fixed car foreign steamer tire, due to the NBS that lug nut is ununified, the kind of current lug nut is a lot, function is also each different, but not there is dust reduction capability, in use dust easily enters in the rotatingshaft of tire from the gap between nut and screw rod, because all parts of inside tires is all comparatively accurate, dust enter the friction that can increase between wheel hub and rotatingshaft, also the stability of tyre rotation be can reduce, usability and the working life of tire affected.
In addition, the general through hole of the tapped hole that existing lug nut matches with screw rod, after assembling, the end of screw rod is directly exposed to the external world, easily by hard deteriorate such as the such as finger stones in the external world in using process.
Model utility content
The purpose of this utility model is that providing a kind of can avoid the screw rod on tire to be exposed to the external world, and having again the dust-proof of dust reduction capability takes turns nut simultaneously.
To achieve these goals, the utility model adopts following technological scheme:
A kind of dust-proof lug nut, comprise spanner auxiliary section and compressed part, and the tapped hole to match with the screw thread on corresponding screw rod, described spanner auxiliary section and the fixed connection of described compressed part, the described portion of pressing has a smooth seal face, described tapped hole is blind hole, the opening of this blind hole is positioned on described seal face, described seal face is also provided with around described opening and the bulge loop coaxial with described tapped hole, the internal surface of described bulge loop is inner cylindrical surface, the diameter of this inner cylindrical surface is equal to or greater than the large footpath of described tapped hole, the outer surface of described bulge loop is conical surface.
Adopt technique scheme, because the tapped hole coordinated with screw rod is blind hole, the end of assembling rear screw rod can be avoided to be exposed to the external world, prevent screw rod by the hard deteriorate in the external world; Simultaneously due to the compressed part of lug nut having smooth seal face, after the wheel hub of seal face and tire is fitted, gap is less, and dust is difficult to the rotatingshaft entering tire from the cooperation position of lug nut and wheel hub, makes lug nut have dust reduction capability.
As further improvement of the utility model, described spanner auxiliary section is provided with hexagon wrench position.By above-mentioned improvement, can the action of lug nut being tightened or unscrewing of user-friendly general spanner.
Further improve as of the present utility model, the blind via bottom of described tapped hole is arc surface.By above-mentioned improvement, the arc surface place of blind via bottom can form a holding space, avoids the bottom surface of tapped hole end contact that is direct and screw rod to cause lug nut easily to loosen.
Accompanying drawing explanation
Fig. 1 is the structural representation of the dust-proof lug nut of the utility model;
Fig. 2 is the sectional view of the dust-proof lug nut of the utility model.
In figure, corresponding sign is as follows:
1-spanner auxiliary section; 2-compressed part;
21-seal face; 3-tapped hole;
4-bulge loop.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As depicted in figs. 1 and 2, the dust-proof lug nut that the present embodiment provides, comprise spanner auxiliary section 1 and compressed part 2, and the tapped hole 3 to match with the screw thread on corresponding screw rod, spanner auxiliary section 1 and the fixed connection of compressed part 2, concrete Placement can be conventional mode, in the present embodiment, spanner auxiliary section 1 and compressed part 2 are the part of integral type, and namely spanner auxiliary section 1 and compressed part 2 are same part.
Spanner auxiliary section 1 is provided with hexagon wrench position, can the action of lug nut being tightened or unscrewing of user-friendly general spanner.Press and portion 2 has a smooth seal face 21, the fitting surface corresponding on the bead seat that this seal face 21 coordinates also must have a smooth seal face, two smooth surfaces are mutually close to and can be prevented dust from entering rotatingshaft from this cooperation position, preferred as one, the surface finishment of the seal face 21 in compressed part 2 and the seal face on bead seat can be improved further, preferably can reach mirror effect, such two compressed part are bonded to each other can be tightr.Tapped hole 3 is blind hole, the opening of this blind hole is positioned on seal face 2, the bottom of this blind hole is arc surface, and the arc surface place of this blind via bottom can form a holding space, avoids the bottom surface of tapped hole 3 end contact that is direct and screw rod to cause lug nut easily to loosen.
Seal face 2 is also provided with the opening around tapped hole 3 blind hole and the bulge loop 4 coaxial with tapped hole 3, the internal surface of bulge loop 4 is inner cylindrical surface, the diameter of this inner cylindrical surface is equal to or greater than the large footpath of tapped hole 3, as the bullport of tapped hole 3, can facilitate the assembling between tapped hole 3 and screw rod; The outer surface of bulge loop 4 is conical surface, is convenient to the location between lug nut and bead seat.
By reference to the accompanying drawings detailed description is done to the utility model above; but mode of execution of the present utility model is not limited in above-mentioned mode of execution; those skilled in the art can make various distortion to the utility model according to prior art; as the outer surface of bulge loop 4 is changed to external cylindrical surface etc. by the conical surface in the present embodiment, these all belong to protection domain of the present utility model.
