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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, the utility model provides a technical solution: high strength check bolt, including bolt 1, nut 6 and reverse bolt 7, the lateral wall of bolt 1 has screw thread 2, circular slot 3 is seted up to bolt 1's right-hand member, the inside wall of circular slot 3 has reverse screw thread 4, the lateral wall of the right-hand member laminating circular slot 3 of bolt 1 sets up elongated slot 5, bolt 1's lateral wall threaded connection has nut 6, bolt 1's right side threaded connection has reverse bolt 7, through set up circular slot 3 at bolt 1's head central point, reverse screw thread 4 has been processed out on the inner wall of this circular slot 3, still set up four elongated slots 5 on bolt 1, elongated slot 5 and circular slot 3 communicate, when nut 6 installs on bolt 1, install in the circular slot 3 of screw thread head with reverse bolt 7, like this, reverse bolt 7 makes the screw thread tip prop up, can be fine prevent that nut 6 on the bolt 1 is not hard up, do benefit to the use.

Furthermore, the number of the long grooves 5 is four, the four long grooves 5 are distributed in a circular array mode, the four long grooves 5 are crossed, and the long grooves 5 are rectangular grooves.

Further, the circular groove 3 is a circular groove, the length of the circular groove 3 is one third of the length of the thread 2, and the center of the circular groove 3 is on the same horizontal straight line with the center of the bolt 1.

Further, the reverse bolt 7 is matched with the circular groove 3, the reverse bolt 7 can be installed in the circular groove 3, the reverse bolt 7 is the same as a bolt on the market, and the reverse bolt 7 is also provided with threads, but the thread direction is opposite.

Furthermore, the long groove 5 is communicated with the circular groove 3, and the length of the long groove 5 is one third of the length of the circular groove 3.
