Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to the technical field of fasteners, in particular to an anti-impact bolt for an automobile chassis.
[ background of the utility model ]
The automobile chassis consists of four parts, namely a transmission system, a running system, a steering system and a braking system. The chassis is used for supporting and mounting the automobile engine and all parts and assemblies thereof to form the integral shape of the automobile, and receives the power of the engine to enable the automobile to move and ensure the normal running. The bolt can be used on the automobile chassis, and because the automobile chassis can bear larger impact in the use process, the existing bolt has poorer impact resistance, and the requirement cannot be well met, so that potential safety hazards can be brought.
[ Utility model ] content
The utility model aims to solve the problems in the prior art and provides an anti-impact bolt for an automobile chassis.
In order to achieve the purpose, the utility model provides an automobile chassis impact-resistant bolt which comprises a bolt body, a fastening nut, a spring limiting nut, a gasket and a buffer spring, wherein thread sections are arranged at two ends of the bolt body, the thread turning directions of the thread sections are opposite, the fastening nut and the spring limiting nut are arranged on the thread sections, the gasket is arranged between the fastening nut and the spring limiting nut, the buffer spring is arranged on the bolt body, and the buffer spring is limited on the bolt body by the spring limiting nut on the thread sections.
Preferably, the fastening nut is a hexagonal nut, and a tapered hole with an internal thread is formed in the fastening nut.
Preferably, the spring limiting nut is a hexagon nut, a truncated cone with external threads is arranged on the spring limiting nut, and a flange is arranged at the bottom of the spring limiting nut.
Preferably, the gasket comprises a fastening nut connecting end, a limiting nut connecting groove and a bolt through hole, the bolt through hole corresponding to the thread section is formed in the gasket, the fastening nut connecting end corresponding to the conical hole is arranged at the top of the bolt through hole, the fastening nut connecting end is a conical truncated cone with an external thread on the side wall, the limiting nut connecting groove corresponding to the conical truncated cone is arranged at the bottom of the bolt through hole, and an internal thread is formed in the inner wall of the limiting nut connecting groove.
The utility model has the beneficial effects that: according to the utility model, the buffer spring and the spring limiting nut are arranged on the bolt body, so that when the bolt body bears larger impact, part of impact force can be absorbed by the buffer spring, and the impact resistance of the bolt body is enhanced; according to the utility model, by arranging the gasket with the fastening nut connecting end and the limiting nut connecting groove, and arranging the fastening nut with the tapered hole and the spring limiting nut with the truncated cone, the connection stability among the fastening nut, the spring limiting nut and the gasket is greatly enhanced, and the phenomenon that the bolt main body and each nut are not easy to loosen is ensured for a long time.
