Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a spacing construction bolt of automobile-used integral type, includes bolt flange head body 1 and automobile body 7, and the top of automobile body 7 is provided with strengthening rib 6, and the below of bolt flange head body 1 is provided with stake body 2, and the below of stake body 2 is provided with the screw body 3, and the lower extreme of stake body 2 is provided with spacing ring 4, and the lower extreme of screw body 3 is provided with circular arc chamfer 5.

Furthermore, the outer diameter of the limiting ring 4 is in transition fit with the reinforcing rib 6, the centering performance and the coaxiality are better, the positioning connection is easy to disassemble and assemble, and the height of the limiting ring 4 is less than or equal to one fourth of the outer diameter of the limiting ring.

Further, the height of the bracket body 2 is equal to or less than that of the reinforcing ribs 6.

Further, the upper end of the bolt flange head body 1 is provided with a hexagonal flange head 8 or an outer plum blossom flange head 9, so that devices with different flange heads can be selected as required, and the application range of the device is wider.

Further, the screw body 3 is in threaded connection with the vehicle body 7, and the threaded connection enables the device and the vehicle body 7 to be limited.
