Title:
DISASSEMBLY-PREVENTING PIPE-CONNECTING DEVICE AND AIR CONDITIONER HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2015/014084
Kind Code:
A1
Abstract:
Disclosed is a disassembly-preventing pipe-connecting device (10), comprising a first connecting pipe (20), a second connecting pipe (30), a first connector (50) connected to the first connecting pipe (20) and a second connector (60) connected to the second connecting pipe (30). The disassembly-preventing pipe-connecting device (10) further comprises an anti-disassembly cap (70), the anti-disassembly cap (70) having a protection cylinder (73) for housing the first connector (50) and the second connector (60), a sliding cylinder (74) extending from one end of the protection cylinder (73) and a snap-hook (76) elastically extending into the protection cylinder (73). The sliding cylinder (74) can move along the second connecting pipe (30), sheathing the protection cylinder (73) on the second connector (60) and the first connector (50) such that a screwing tool cannot exert a force directly on the first connector (50) and the second connector (60). The snap-hook (76) can block the second connector (60) or the first connector (50) to prevent the protection cylinder (73) from moving in reverse. Hence, there is no way for the screwing tool to exert a force on the first connector (50) and the second connector (60) after removing the anti-disassembly cap (70), thus the disassembly-preventing pipe-connecting device prevents the first connector (50) and the second connector (60) from being erroneously disassembled, thus preventing leakage of a cooling medium.
