Abstract
The utility model provides a novel anti-loosening tire screw bolt, which comprises a screw rod and a screw nut, wherein the screw nut is provided with a movable gasket in a matched way, a flange is formed at the end part of the movable gasket, and the movable gasket is provided with a regular-prismatic-shaped edge corner section with even edges. Therefore the novel anti-loosening tire screw bolt breaks through the construction form of the traditional tire screw bolt, the movable gasket is provided with the edge corner section, in addition, the edge corner section is in a regular prismatic shape with even edges and has a polyhedral edge corner peripheral surface similar to the screw nut, when the movable gasket cannot be easily dismounted as the flange and the screw bolt or corresponding screw bolt holes formed in a wheel hub are clamped through corrosion or deformation, the movable gasket and the flange cannot be pulled out through the connecting intensity of the screw nut and the movable gasket, or even when the screw nut is separated from the movable gasket, people can realize the pulling through using a spanner for biting the edge corner section arranged on the movable gasket so that the flange and the screw bolt or the corresponding screw bolt holes formed in the wheel rub are gradually loosened and are dismounted. Compared with the prior art, the novel anti-loosening tire screw bolt has the advantages that on the basis of preventing the screw rod from being easily fracture, the whole screw bolt is easier to dismount, the structure is simple and reasonable, and convenience and practicability are realized.
Description
Technical field
The utility model relates to the bolt of automobile tire field of components, is specifically related to a kind of easily detachable Novel anti-loosening tire bolt.
Background technique
At present, the known dismounting for the ease of wheel, the screw diameter in automobile tire bolt assembly is than the corresponding little 4-6mm of diameter of bolt hole on wheel hub, and lug nut is wherein a plane with the contact end face of wheel hub and is parallel with wheel hub plane.Result after above-mentioned bolt assembly is installed is: after 1. wheel is loaded onto, due to gravity and above-mentioned bolt hole and the poor factor of screw diameter, cause that axle centerline and wheel center line can not, on same axis, form irregular running while causing rotation of wheel; 2. moment of torsion transfer route when automobile running is: moment of torsion passes to bolt through wheel disc, then passes to wheel hub (being wheel).Because above-mentioned bolt hole, screw diameter are poor, after automobile running a period of time, to make bolt rotate in advance an angle relative to bolt hole, active force between bolt hole and screw rod is only acted on a bit, in the time of acceleration suddenly in vehicle traveling process and this conversion moment of torsion of emergency braking, will on this force position, form great shearing stress, cause bolt to fracture.Just because of this, the position that tire bolt of the prior art fractures is substantially all on the point of contact of screw rod and wheel hub.
In order to address the above problem, Chinese utility model patent CN200920179957.1 discloses a kind of positioning energy-saving type tire bolt assembly, comprise: location lug nut and the bolt matching, wherein locate lug nut and comprise nut and locating sleeve packing ring (packing ring), both linkage structures are: the abutting end riveted of described nut and locating sleeve packing ring links together, nut and locating sleeve packing ring can be linked together with the relative rotation, or, described nut and locating sleeve packing ring are solidified as a whole, the pore road of described locating sleeve packing ring is coaxial with described nut inner hole and be connected, at the free-ended end face of described locating sleeve packing ring, stretch out vertically and be provided with a hollow positioning table (flange), outer shape, size and the wheel disc bolt hole of this positioning table adapt, the pore road of its hollow endoporus and described locating sleeve packing ring is concentric and be interconnected, and its diameter of bore and described bolt match, make described positioning table when mounted be plugged in described wheel disc (wheel hub) bolt hole and be arranged in the gap between the described bolt in this wheel disc bolt hole.After wheel is loaded onto, by nut with the positioning table of locating sleeve packing ring be inserted in the space existing between wheel disc bolt hole and tire bolt bar, this screw rod that has just reduced to a great extent wheel disc bolt hole and local power shrinking diameter gap between the two, also plays the effect of support to wheel disc.Particularly, in the time that the profile of positioning table is taper and cylindrical combination, can make wheel automatic alignment true centric.In the time of the change in torque such as automobile emergency acceleration and emergency braking, due to be positioned positioning table occupy-place on guide sleeve packing ring and significantly reducing of the gap between wheel disc bolt hole and screw rod, and the area of contact of wheel disc bolt hole and screw rod is increased, the shearing stress that effect forms on contact position significantly declines, and can farthest avoid the tire bolt phenomenon that fractures.But also there is defect in this model utility in actual use, when after permanent use, positioning table and screw rod or wheel disc bolt hole are because of corrosion or to be out of shape the stuck positioning pipe packing ring that causes not quick detachable, and the join strength of nut and positioning pipe packing ring is not enough to positioning pipe packing ring to extract together with positioning table, even nut departs from positioning pipe packing ring, now be difficult to positioning pipe packing ring to pull down, bring many troubles to people.
Given this, this case inventor further investigate the problems referred to above, then has this case to produce.
Model utility content
The purpose of this utility model is to provide a kind of whole bolt more quick detachable, simple and reasonable, convenient and practical Novel anti-loosening tire bolt.
In order to achieve the above object, the utility model adopts such technological scheme:
A kind of Novel anti-loosening tire bolt, the nut that comprises screw rod and mate with screw rod, described nut is equipped with and pads the driving washer of being located between nut and wheel hub and being articulated with the coaxial activity of nut; The end of described driving washer is formed with coupling and stretches into the flange between respective bolt holes on described screw rod and wheel hub; Described driving washer has the corner angle section of the regular prism shape that is even number bar rib.
Above-mentioned driving washer entirety is the regular prism shape of even number bar rib.
Above-mentioned driving washer is positive eight prism-shaped.
Above-mentioned driving washer and above-mentioned nut activity rivet together.
Above-mentioned flange and above-mentioned driving washer are structure as a whole.
Adopt after technique scheme, Novel anti-loosening tire bolt of the present utility model, break through the structural form of traditional anti-loosening tire bolt, its driving washer has corner angle section, and this corner angle section is the regular prism shape of even number bar rib, be the shapes such as corner angle Duan Chengzheng six prisms or positive eight prisms, there is the multiaspect corner angle side face of similar nut, can supply spanner interlock, in actual use, when after permanent use, respective bolt holes on flange and screw rod or wheel hub is because of corrosion or to be out of shape the stuck driving washer that causes not quick detachable, and the join strength of nut and driving washer is not enough to driving washer to extract together with flange, when even nut has departed from driving washer, people can pull by the corner angle section on spanner interlock driving washer, make the respective bolt holes on flange and screw rod or wheel hub loosening gradually, and then can pull down easily driving washer, compared with prior art, Novel anti-loosening tire bolt of the present utility model, its flange is avoiding screw rod to be subject to the concentrated stress of respective bolt holes on wheel hub, prevent on the basis of screw rod frangibility, corner angle section makes whole bolt more quick detachable, simple and reasonable, convenient and practical.
