Summary of the invention
The purpose of the utility model is to provide a kind of hexagon bolt with flange, a kind of structure is simple, it is easy to use more Safety, suitable for the bolt of fastening automobile, to solve problem of the prior art.
The technical solution that the utility model is taken to achieve the above object are as follows: a kind of automobile-used hexagon bolt with flange, Including bolt body, the bolt body includes the bolt head and screw rod being arranged in a mutually vertical manner, and the bolt head includes Have a hexagon-head and ring flange being mutually permanently connected, the hexagon-head upper end is provided with transition chamfering one, hexagon-head with Ring flange is connected with each other by setting knuckle, and the ring flange lower end is provided with the Step-edge Junction being fixedly connected with ring flange Structure is provided with transition chamfering two on step structure, and the step structure is mutually permanently connected with screw rod, and the screw rod is far from flange One end of disk is equipped with a centrum portion, and the end face in the centrum portion is perpendicular to the axle center of the screw rod, and the screw rod is equipped with outer spiral shell Line, the external screw thread are placed in screw rod tail position corresponding with nut, and one section is equipped between the transition chamfering two and external screw thread Recess portion identical with root diameter, the recess portion outer sheath covers have a circle sealing ring, it is close that a circle are coated on the external screw thread Gluing is sealed, the ring flange is provided with inner and outer rings connected in star close to a side end face of screw rod, and the inner ring connected in star is close to The outer wall of step structure is arranged, and the external annular groove is arranged along the edge of ring flange, divides in the inner and outer rings connected in star It is not provided with the first rubber seal and the second rubber seal.
The outer diameter of the sealing ring is equal to externally threaded outer diameter.
The chamfer angle of the transition chamfering one is set as 60 degree.
The chamfer angle of the transition chamfering two is 60 degree.
The conical surface angle in the centrum portion is 90 degree.
The utility model has the following beneficial effects:
By sealant coating, the use of sealing ring, the first rubber seal and the second rubber seal, multiple sealing knot The use of structure can greatly improve the leakproofness between the flange face hex bolts and connected part.By on the downside of ring flange Step structure with transition chamfering two effectively improves the fastening effect between connector.The utility model uses screw rod cone Portion's design, while being installed automatically and guaranteeing fastening force, there is automatic guiding function, efficient can assemble.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of the utility model.
Fig. 3 is the bottom view of the utility model.
Specific embodiment
Specific embodiment of the present utility model is made a detailed explanation with reference to the accompanying drawing.
As shown in Figure 1-Figure 3, a kind of automobile-used hexagon bolt with flange, including bolt body, the bolt body include There are the bolt head 1 and screw rod 2 being arranged in a mutually vertical manner, the bolt head 1 includes 3 He of hexagon-head being mutually permanently connected Ring flange 4,3 upper end of hexagon-head are provided with transition chamfering 1, and transition chamfering 1 can effectively remove on hexagon-head Burr improves aesthetics and to easily facilitate removing for hexagon-head 3 stubborn, and hexagon-head 3 and ring flange 4 are by being arranged 6 phase of knuckle It connects, 4 lower end of ring flange is provided with the step structure 7 being fixedly connected with ring flange 4, is provided on step structure 7 Cross chamfering 28, transition chamfering 28 can with the screw hole that matches is even closer links together.The step structure 7 and screw rod 2 are mutually permanently connected, and the screw rod 2 is equipped with a centrum portion 9 far from one end of ring flange 4, the end face in the centrum portion 9 perpendicular to The axle center of the screw rod, the conical surface angle in the centrum portion 9 are 90 degree.By being equipped with one far from one end of ring flange 4 in screw rod 2 Centrum portion 9, so that while installation guarantees fastening force, more convenient installation, so that the efficiency of installation improves.The screw rod 2 are equipped with external screw thread 10, and the external screw thread 10 is placed in 2 tail portion of screw rod position corresponding with nut, the transition chamfering 28 with outside One section of recess portion 11 identical with 10 internal diameter of external screw thread is equipped between screw thread 10,11 outer sheath covers of recess portion have a circle sealing ring, A circle sealant coating is coated on the external screw thread 10, stating ring flange, that a side end face of screw rod is provided with inside and outside annular is recessed Slot 12,13, the inner ring connected in star 12 are close to the setting of 7 outer wall of step structure, and the external annular groove 13 is along ring flange 4 Edge setting, be respectively arranged with the first rubber seal 14 and the second rubber seal in the inner and outer rings connected in star 12,13 Circle 15.Pass through sealant coating, the use of sealing ring, the first rubber seal 14 and the second rubber seal 15, multiple sealing The use of structure can greatly improve the leakproofness between the flange face hex bolts and connected part.
