Referring to fig. 3 to 5, specific configuration examples of the adaptive fastening pipe clamp are shown.

Referring to the relevant figures, the self-adaptive fastening pipe clamp mainly comprises three components of a pipe clamp body 100, a stop assembly 200 and a return force assembly 300 in structure.

The pipe clamp body 100 is a structural body and is used for carrying other components.

The stop assembly 200 comprises two rotation stop blocks 210, a placement part 110 matched with the two rotation stop blocks 210 is arranged on the pipe clamp body 100, the two rotation stop blocks 210 are rotationally and symmetrically and fixedly arranged in the placement part 110, a round hole 120 which can be penetrated by a bolt and a screw is arranged on the pipe clamp body 100 and is communicated with the placement part 110, one end of the return force assembly 300 is connected with the pipe clamp body 100, and the other end of the return force assembly is abutted against the rotation stop blocks 210 to provide a return force for the rotation stop blocks 210.

Further, the two rotation stoppers 210 are rotatably and symmetrically disposed in the mounting portion 110 of the pipe clamp body 100, and a gap space for allowing the bolt/screw to pass through is formed therebetween, and the gap space cooperates with the return force assembly 300 to lock the bolt/screw between the two rotation stoppers 210.

The size of the gap space formed here can vary with the relative rotation between the two rotation stops 210, and in particular, can become progressively larger or smaller depending on the direction of the relative rotation between the two rotation stops 210.

The rotation stopper 210 includes a stopper body 211, a support column 212, and a cam 213, the stopper body 211 being cylindrical as a whole, the stopper body 211 extending outwardly along both end faces to form the support column 212, the side face of the stopper 211 extending spirally outwardly to form the cam 213.

The support column 212 is engaged with the guide groove 130, and the support column 212 is integrally caught in the guide groove 130.

The cam 213 includes a contact surface 214 and a latch surface 215, the contact surface 214 abuts against the return force assembly 300, the latch surface 215 is used for being matched with threads on the surface of a bolt/screw, and the latch surface 215 and the threads are mutually meshed in practical use.

The return force assembly 300 includes two return force ribs 310, the two return force ribs 310 are respectively disposed in the placement portion 110, one end of the return force ribs is connected with the pipe clamp body 100, and the other end of the return force ribs is abutted against the contact surface 214 of the rotation stop block 210. For providing a certain return force to the rotation stop block 210 such that the latch surface 215 of the rotation stop block 210 has good contact with the threads of the bolt/screw surface.
