Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection technology, specifically, it relates to a quick-connect locking device for threaded pipe fittings. Background Technology

[0002] In piping engineering, threaded pipe fittings are usually connected manually by tightening them.

[0003] Utility model CN218863548U discloses a non-disassembly quick-connect coupling that allows for easy disassembly while enabling pipe connection, and can control the opening and closing of internal passages. The key technical point is that it is used for inserting and connecting pipe ends, including a pipe shell body, a sealing end, a passage control core, and a quick-connect locking mechanism. The pipe shell body has a connecting end and a sealing end at its two ends, respectively. An assembly cavity is provided inside the pipe shell body. The sealing end and the sealing end are detachably and sealed together, and the sealing end has a connecting channel communicating with the assembly cavity. The passage control core is located in the assembly cavity to control the opening and closing of the quick-connect plug passage. The quick-connect locking mechanism includes a locking element movably mounted on the side wall of the pipe shell body. The passage control core and the quick-connect locking mechanism are linked to control the locking element to switch between a locked state and an unlocked state. When the locking element is in the locked state, the pipe inserted into the connecting end is locked and fixed; when the locking element is in the unlocked state, the pipe inserted into the connecting end can be freely pulled out.

[0004] However, the above-mentioned patents still have the following problems: after long-term use, the threaded grooves at the pipe joints are prone to wear due to vibration, fluid erosion or material aging, resulting in sealing failure. The device is not designed with a compensation structure for vibration or thermal expansion and contraction, and is prone to loosening under dynamic working conditions. For pipes that require auxiliary support, the device cannot provide mechanical fixation, and additional brackets need to be installed, which increases the complexity of construction.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content
