Abstract
The utility model relates to a quick fastening pipe joint, which comprises a pipe joint, a pipe which is sheathed into the pipe joint, a locking ring which is used for chucking the pipe, and fastening nuts which are sheathed into the pipe and the locking ring. The end parts of both ends which can be mutually enclosed of the locking ring are respectively provided with connecting teeth which can be mutually abutted. The connecting teeth are in the shape of sawtooth. When the utility model is installed, the pipe can be chucked by sheathing the pipe into the pipe joint and tightening the pipe joint to make the connecting teeth on the locking ring support mutually to make the connecting teeth slip in a teeth slot. The utility model has the advantages of compact structure, convenient installation, and good tightness, which can be widely used for connecting and installing the pipes, such as aluminum plastic laminated 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 dock mutually so that chimeric 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, the two end ends that can close up mutually of described locking ring are respectively equipped with the attachment tooth that can dock mutually, this attachment tooth indention shape.
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 in the aforementioned tube joint.
Referring to Fig. 1 to Fig. 2, 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.
The two end ends that can close up mutually of locking ring 3 are respectively equipped with the attachment tooth 31 that can dock mutually, these attachment tooth 31 indention shapes.
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 mutually and then is slipped in the teeth groove, and so bidentate is chimeric just can tighten pipe 2.
Claims (1)
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 cover installs to the fastening nut on pipe and the locking ring, it is characterized in that the two end ends that can close up mutually of described locking ring are respectively equipped with the attachment tooth that can dock mutually, this attachment tooth indention shape.
