Description

Technical Field

[0001] This utility model relates to the field of dental connector technology, and in particular to a rotating internal snap-fit ​​dental connector. Background Technology

[0002] Pipe threads are critical components used for pipe connections in fluid transport systems (such as fire-fighting water supply, industrial pipelines, and civil water supply and drainage). Their connection reliability directly determines the safety and stability of fluid transport. In practical applications, pipe threads are frequently subjected to fluid pressure shocks (such as pressures exceeding 1.6 MPa in fire-fighting scenarios), and are often accompanied by pipeline vibrations and position adjustments. If the connection becomes loose or detached, fluid leakage can easily occur, resulting not only in resource waste but also potential safety accidents (such as disruption of fire rescue operations or industrial fluid pollution).

[0003] Existing pipe thread interfaces mostly adopt a single thread connection or a simple snap-fit ​​connection structure: a single thread connection relies on thread engagement for fixation, and after long-term use, the thread is prone to stripping due to wear and corrosion. Moreover, the thread connection has no anti-loosening and reset function, and it is easy to loosen when subjected to vibration or pressure fluctuations, making it difficult to tighten. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a rotating internal threaded connector that can be reset through a reset hole, making it easy to double rotate and lock, and not easy to fall off.

[0005] This utility model also provides a rotating internal threaded connector as described above, comprising: The fixed ring has an inner cavity and a threaded structure on its inner side; The interface tube is located inside the fixed ring; The locking buckle is located at the lower end of the interface tube and is symmetrically arranged. The snap-fit ​​blocks are symmetrically arranged on the outer wall of the interface pipe and are located on the inner wall of the fixed ring.

[0006] According to the present invention, a rotary internal threaded pipe interface is provided, wherein four sliding posts are uniformly and fixedly connected to the outer wall of the interface pipe, and a sliding positioning groove is provided between the sliding posts and the fixed ring.
