Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the high-strength anti-loosening U-shaped bolt includes a U-shaped rod 1, and a first screw 2 and a second screw 3 connected to the U-shaped rod 1, wherein both ends of the first screw 2 and the second screw 3 far away from the U-shaped rod 1 are connected to a nut 12 by screw threads; first screw rod 2 fixed connection is in the one end of U type pole 1, and the other end of U type pole 1 is equipped with first screw 4, and the lower extreme fixedly connected with third screw 5 of

second screw rod

3, 4 threaded connection on U type pole 1 of third screw 5 accessible first screw.

The concave part of the bottom of the U-shaped rod 1 is connected with the anti-loosening rubber mat 11, so that the U-shaped rod 1 and the pipe fitting 13 are always in a pressing state, and looseness is avoided.

Referring to fig. 2, the clamping device further comprises a transfer block 6, a fourth screw 7 is fixedly connected to the lower side of one end of the transfer block 6, the fourth screw 7 can be connected in the first screw hole 4 in a threaded manner, a second screw hole 8 is formed in the other end of the transfer block 6, a positioning hole 9 is formed in the second screw hole 8, and an arc-shaped surface 10 is arranged on the lower side of one end, away from the fourth screw 7, of the transfer block 6 and matched with the arc surface of the to-be-fixed member, so that the transfer block is in contact with the to-be-fixed member to play a role in pressing; the third screw rod 5 can be connected in the second screw hole 8 in a threaded manner, and when the third screw rod 5 is connected in the second screw hole 8 in a threaded manner, the lower end of the second screw rod 3 is positioned in the positioning hole 9.

In the actual production process, a plurality of types of the adapter blocks 6 can be produced, for example, the length of each adapter block 6 is different, and the radian of the arc-shaped surface 10 of each adapter block is calculated to be different so as to adapt to pipes with various sizes.
