Description

Technical Field

[0001] The utility model relates to the technical field of screw joints, in particular to a screw joint for an anti-seismic support hanger. Background Technique

[0002] The existing screw joint is an M12 - M16 female thread, with a length of 40mm - 60mm, the narrowest part is 15mm, and the widest part is 18mm hexagonal extended nut. Its function is to connect the expansion anchor bolt of the anti-seismic support hanger with the full-thread screw to achieve the installation purpose. During installation, the expansion anchor bolt and the full-thread screw need to be screwed into 1 / 2 of the length of the screw joint respectively. To ensure consistent connection strength, in the existing products, the appearance of the screw joint is neither transparent and visible nor has scale marks, and it is very difficult for installers to ensure the consistency of the screwing depth. During the installation process in some positions, installers need to use a ruler to make marks on the expansion anchor bolt and the full-thread screw before installation.

[0003] The existing patent (publication number: CN210715465U) discloses a screw joint for an anti-seismic support hanger system, in which the limit pin is located in the middle of the screw joint, thus limiting the positions of the expansion anchor bolt and the full-thread screw, which can solve the problem of inaccurate screwing positions at both ends of the screw joint and reduce product quality problems caused by human errors, etc. At the same time, it can reduce the position marking of the expansion anchor bolt and the full-thread screw by installers, reduce the procedures, and can also be installed calmly in places with insufficient light, accelerating the construction speed. In the process of implementing this solution, it is found that the following problems exist in the existing technology and have not been well solved:

[0004] This joint uses a thread structure to complete the connection during use, but the thread is prone to rust due to the influence of external moisture, etc. during long-term use, resulting in difficult disassembly.
