Embodiment
See also Fig. 1 to Fig. 3, the pipe fitting joint 100 of preferred embodiments of the present invention is used for being connected with first pipe fitting 200.Pipe fitting joint 100 comprises one second pipe fitting 10 and a fastener head 20.Second pipe fitting 10 comprises the connection pipeline section 12 that the multistage radial dimension is different.First pipe fitting 200 is connected the cooperation of pipeline section 12 sizes and connects with one section.The joint of tight first pipe fitting 200 of fastener head 20 reeds and second pipe fitting 10.
Owing to adopt the different connection pipeline section 12 of multistage radial dimension, pipe fitting joint 100 can mate with other pipe fittings of multiple size, and versatility is good.
In this mode of execution, first pipe fitting 200 is a flexible tube, and like plastic tube, second pipe fitting 10 is a rigid pipe, like steel pipe.Second pipe fitting 10 comprises the connecting end 14 and the four sections connection pipeline sections 12 that stretch into first pipe fitting 200.Four sections connect pipeline sections 12 outer without leave near one section of connecting end 14 to becoming big gradually away from a section of connecting end 14.The internal diameter of first pipe fitting 200 is slightly larger than second external diameter near the connection pipeline section 12 of connecting end 14, and so, first pipe fitting 200 can closely be set in the second connection pipeline section 12 near connecting end 14.Tight first pipe fitting 200 of fastener head 20 reeds is connected pipeline section 12 with second near connecting end 14.
In other embodiments, first pipe fitting can be rigid pipe, and second pipe fitting is flexible tube and comprises a connecting end that is inserted in first pipe fitting.Multistage connects pipeline section interior without leave near one section of connecting end to diminishing gradually away from a section of connecting end.
So, when urceolus 26 when the direction spiral shell near first pipe fitting 200 advances, compressing ring 262 will promote the central shaft slip of slide block 28 to pipe fitting joint 100, utilize the joint of tight first pipe fitting 200 of fastening face 282 reeds and second pipe fitting 10.
Particularly, ring-type slide unit 24 is rotationally connected with inner core 22, and promptly ring-type slide unit 24 can rotate with respect to inner core 22 along the central shaft of pipe fitting joint 100.So; When the slide block 28 and the stiction of compressing ring 262 and first pipe fitting 200 excessive and can't rotate urceolus 26 time; Can pass through to rotate inner core 22 and further oppress the central shaft slip of slide blocks 28 to pipe fitting joint 100, thus the joint of further fastening first pipe fitting 200 and second pipe fitting 10.
More specifically, inner core 22 comprises relative with ring-type slide unit 24 first end face 222, the first ring-type location piece 224 and one second a ring-type location piece 226.First end face 222 offers a ring-type chute 228.Ring-type slide unit 24 comprises one and inner core 22 second opposed end faces 246 and two first screws 248.The circumference of second end face, 246 corresponding ring-type chutes 228 offers two first screw 24a.Each first screw 248 comprises a nut 24b and a double-screw bolt 24c.The interior external diameter difference of ring-type chute 228 is greater than the diameter of nut 24b.The internal diameter of the first ring-type location piece 224 is greater than the external diameter of the second ring-type location piece 226 and less than the external diameter of ring-type chute 228.The external diameter difference of the internal diameter of the first ring-type location piece 224 and the second ring-type location piece 226 is less than the diameter of the nut 24b diameter greater than double-screw bolt 24c.Nut 24b is contained in the ring-type chute 228.The first ring-type location piece 224 and the second ring-type location piece 226 are fixed in first end face 222 so that nut 24b is defined in the ring-type chute 228.A plurality of double-screw bolt 24c are screwed into a plurality of first screw 24a respectively.In the practical application; Can on the first ring-type location piece 224 and the second ring-type location piece 226, respectively offer two through hole 22a; On first end face 222, offer four the second screw 22b of corresponding through hole 22a; And adopt four second screw 22c to be screwed into corresponding the through hole 22a and the second screw 22b, thereby the first ring-type location piece 224 and the second ring-type location piece 226 are fixed in first end face 222.
The quantity of first screw 248, the first screw 24a, the second screw 22c and the second screw 22b can be not limited to this mode of execution, and gets other suitable numbers as required.Certainly, the first ring-type location piece 224 and the second ring-type location piece 226 also can be fixed in first end face 222 through other modes.Ring-type slide unit 24 also can be rotationally connected through other modes and this inner core 22.
Preferably, inner core 22 is also offering a plurality of lever lockhole 22d away from urceolus 26 1 ends, with convenient inner core 22 is applied lever so that bigger torsion to be provided, further the joint of fastening first pipe fitting 200 and second pipe fitting 10.
In a word; Those skilled in the art will be appreciated that; Above mode of execution only is to be used for explaining the present invention; And be not to be used as qualification of the present invention, as long as within connotation scope of the present invention, appropriate change that above embodiment did is all dropped within the scope that the present invention requires to protect with changing.
