Abstract
The utility model relates to a quick fastening pipe joint, which comprises a pipe joint, a pipe which is sheathed in the pipe joint, a locking ring which clamps the pipe, and a fastening nut which is sheathed with the pipe and the locking ring. Connecting teeth are arranged on at least one end of both ends of the locking ring, and both the ends can be held together. Two connecting teeth are separately and parallelly arranged at the edge of the end. When the utility model is installed, the pipe is sheathed in the pipe joint, and the pipe is tightened; the connecting teeth on the locking ring are pressed to be bent for clamping the pipe. The utility model has the advantages of compact structure, convenient installation and good sealing performance. The utility model is widely suitable for the connection and the installation of the pipes like the aluminum plastic composite pipes, etc.
Description
The utility model relates to pipe fitting, particularly a kind of pipe joint of tightening fast.
The useful thread seal bar of existing pipe joint rotary joint style pipe joint also has the plug bush type pipe joint.Adopt the pipe joint of plug bush type structure at present mostly, locking ring is housed, again suit nut, installation sleeve water inlet pipe then in it.It is mainly by locking ring chucking water pipe, and its shortcoming is to need dismounting pipe joint earlier when assembling, and the nut of screwing on again behind the suit pipe is fastening, and assembly process is loaded down with trivial details, uses trouble.
The purpose of this utility model provides a kind of improved pipe joint of tightening fast, and as long as it is with the pipe cover pipe joint of packing into, and is then fastening, make attachment tooth on the locking ring withstand so that bending after can tighten pipe.
A kind of pipe joint of tightening fast described in the utility model comprises pipe joint, overlap the pipe of the pipe joint of packing into, the locking ring of chucking pipe, and cover installs to the fastening nut on pipe and the locking ring, end in two ends that can close up mutually of described locking ring is provided with attachment tooth with the upper end portion, this attachment tooth has two, and is parallel respectively and be arranged on the edge of this end end side by side.
The utility model compact structure, reasonable in design, easy for installation, good airproof performance uses reliably, is widely used in the connection and the installation of pipes such as aluminium-plastic composite pipe, crosslinked polyethylene pipe, plastic cement water pipe.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is that each part of a kind of pipe joint of tightening fast decomposes the assembling schematic representation.
Fig. 2 is the locking ring structural representation that an end has tooth in the aforementioned tube joint.
Fig. 3 is the locking ring structural representation that two ends have tooth in the aforementioned tube joint.
Referring to Fig. 1 to Fig. 3, a kind of pipe joint of tightening fast comprises pipe joint 1, overlaps the pipe 2 of the pipe joint 1 of packing into, the locking ring 3 of chucking pipe 2, and cover installs to the fastening nut 4 on pipe 2 and the locking ring 3.
End in two ends that can close up mutually of locking ring 3 is provided with attachment tooth 31 with the upper end portion, and this attachment tooth 31 has two, and is parallel respectively and be arranged on the edge of this end end side by side.
During use, pipe 2 is overlapped the pipe joint 1 of packing into, owing to install locking ring 3 in advance in the pipe joint 1, and the fastening nut 4 of screwing on, therefore after pipe 2 plug-in mountings are gone in the pipe joint 1, as long as tighten fastening nut 4 with pipe tongs.Because when tightening fastening nut 4, the attachment tooth 31 on the locking ring 3 is withstood and then is crooked, and so crooked bidentate just can tighten pipe 2.
Claims (3)
1. pipe joint of tightening fast, it comprises pipe joint, overlap the pipe of the pipe joint of packing into, the locking ring of chucking pipe, and overlap the fastening nut that installs on pipe and the locking ring, it is characterized in that the end in two ends that can close up mutually of described locking ring is provided with attachment tooth with the upper end portion, this attachment tooth has two, and is parallel respectively and be arranged on the edge of this end end side by side.
