Description
The technical field is as follows.
The utility model relates to auto-parts technical field especially involves an automobile-used bolt assembly.
Background
The bolt is the cylindrical threaded fastener of adapted nut, realize being connected through the bolt between the wheel of car and the steel ring, most simple structure of car bolt on the present market, all be integrated into one piece formula, its stability and crushing resistance are all comparatively general after the installation, holistic intensity is not high, if can appear connecting untight phenomenon when receiving comparatively heavy external pressure, simultaneously when the car driving when the road surface of jolting, the automobile body of continuous vibration can bring pressure for the bolt, make car bolt take place not hard up phenomenon very easily for a long time, stability is relatively poor.
Disclosure of Invention
The utility model discloses the purpose: for overcoming the defect that prior art exists, the utility model provides an automobile-used bolt assembly.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an automobile-used bolt assembly, includes first bolt, second bolt and nut, its characterized in that: the novel nut is characterized in that a hexagonal head is arranged on the first bolt, a flange plate is fixedly connected to the bottom of the hexagonal head, a fixed rod is fixedly connected to the bottom of the flange plate, a first screw rod is fixedly connected to the bottom of the fixed rod, the second bolt comprises a nut and a second screw rod, a reinforcing rib column is arranged in the middle of the first bolt, a cavity for the second screw rod to pass through is formed in the reinforcing rib column, a first screw hole matched with the first screw rod is formed in the nut, and a second screw hole matched with the second screw rod is formed in the nut.
Through taking above-mentioned technical scheme, can be so that the structural toughness reinforcing of first bolt through the strengthening rib post, add the second bolt in the inside of first bolt, correspond on the nut have with first bolt and second bolt complex screw hole, screw up the back with first bolt and screw up the second bolt once more, carry out the secondary installation, the degree of depth of installation is more simultaneously, and is more stable, through adopting two segmentation structures, has promoted holistic intensity, compact structure, and the practicality is stronger.
The utility model discloses the further scheme does: the nut is provided with a limiting surface abutted against the bottom of the first screw rod, and an elastic cushion is arranged between the limiting surface and the bottom of the first screw rod.
Through taking above-mentioned technical scheme, in the design of theory, the bolt is resolute with the car wheel with the nut cooperation, outer steel ring, when interior steel ring locking, the spacing face of nut this moment with first screw rod bottom butt, there is the error in actual processing, the spacing face of nut should be can't bump first screw rod bottom when locking during the design, there is the clearance between spacing face and the first screw rod bottom, just can realize the locking effect, through addding the cushion, the thickness of cushion is greater than clearance length, in the assembling process, the cushion receives the extrusion of first screw rod, can produce the interact power, make locking effect better, and reduce the wearing and tearing between first screw rod and the spacing face of nut.
The utility model discloses the further scheme does: and the hexagonal head is provided with a nut placing groove.
Through adopting above-mentioned technical scheme for the nut of second bolt is in the inside of hexagon head, makes the whole look more pleasing to the eye.
The utility model discloses the further scheme does: the surface of the first bolt is provided with an anti-loosening strip.
By adopting the technical scheme, when the automobile hub and the steel ring are connected by the automobile bolt assembly, the loosening strip can be further clamped into the corresponding part of the automobile hub, so that the first bolt cannot fall off from the automobile hub, the connection strength between the automobile hub and the steel ring is effectively enhanced, and the safety is improved.
The utility model discloses the further scheme does: the top of the hexagonal head is fixedly connected with a zinc cover.
By adopting the technical scheme, the zinc cover can prevent the hexagonal head and the nut from being subjected to electrochemical corrosion, and the service life of the bolt is prolonged.
The utility model discloses the further scheme does: the nut is provided with a hexagonal groove.
By adopting the technical scheme, the hexagonal groove is formed in the nut, so that the second bolt can be conveniently assembled and disassembled by using a hexagonal wrench.
The utility model has the advantages that: more stable, through adopting two segmentation structures, promoted holistic intensity, compact structure, the practicality is stronger.
