FAST CONNECTION PIPE
Document Type and Number:
WIPO Patent Application WO/2016/169291
Kind Code:
A1
Abstract:
A fast connection pipe comprises a core pipe (10), a housing sleeve (30) and a holding pipe sleeve (40). The housing sleeve (30) is sleeved outside the core pipe. One end of the housing sleeve (30) is provided at one end of the core pipe, and an accommodation space for a pipe material to be inserted in is provided between the other end of the housing sleeve (30) and the core pipe. The holding pipe sleeve (40) is sleeved outside the core pipe and located in the housing sleeve (30). The holding pipe sleeve (40) matches the housing sleeve (30) by a space. The holding pipe sleeve (40) comprises an annular pipe sleeved outside the core pipe and a plurality of holding pieces connected to the annular pipe. An inner side wall of the housing sleeve (30) is provided with a first gradually-reducing section (32) having an inner diameter gradually reducing in a direction away from the other end of the core pipe. A holding piece (42) is provided with a second gradually-reducing section (421) having an outer diameter gradually reducing in a direction away from a second threaded section (31). The second gradually-reducing section (421) matches the first gradually-reducing section (32). The fast connection pipe comprises a simple structure of the holding pipe sleeve (40) and the housing sleeve (30), and achieves, by holding the pipe material via the holding pipe sleeve (40), a better effect of preventing the pipe material from breaking loose.
