The purpose of the utility model is to overcome above-mentioned limitation, it is more preferable to provide a kind of fastening effect, is not easy to loosen, uses peace
It is complete reliable, improve the clinch fastener of racing car security performance.
The purpose of this utility model is achieved through the following technical solutions：A kind of multiple-effect racing car clinch fastener, including it is outer
Hex screw, outer-hexagonal bolts side are provided with the first groove, the first threaded hole, the first threaded hole are provided in the middle part of the first bottom portion of groove
It is connected through a screw thread with the first soket head cap screw, the first preload bullet is provided between the first soket head cap screw and the first bottom portion of groove
Spring, spring washer and plain cushion are nested on the stud front end of outer-hexagonal bolts, and stud rear end and the nut of outer-hexagonal bolts pass through screw thread
Connection, nut side wall are provided with the second groove, are provided with the second threaded hole in the middle part of the second bottom portion of groove, in the second threaded hole and second
Hex screw is connected through a screw thread, and the second preloading spring is provided between the second soket head cap screw and the second bottom portion of groove.
Preferably, the center line of the first threaded hole and the centerline direction of outer-hexagonal bolts are parallel.
Preferably, the center line of the internal thread hole of nut is vertical with the centerline direction of the second threaded hole.
Preferably, plain cushion radius be more than the first threaded hole center line and the center line of outer-hexagonal bolts between away from
From.
Preferably, when the first soket head cap screw screws tight, stud rear end is in contact with plain cushion surface, hexagonal spiral shell in second
When oncomelania is tight, stud rear end is in contact with outer-hexagonal bolts stud rear end surface.
In conclusion the utility model has the following advantages：Fastening structure is locked using multiple-effect, fastening effect is more preferable, no
Easily loosen, it is safe and reliable, improve the security performance of racing car.
