Abstract
The utility model aims to provide a pipe line connecting lathe dog, which can cause assembly and clamp to be tight and safe; disassembly is easy, and a screw bolt and a screw nut and a lathe dog are inseparable. Consequently, the utility model overcomes the defect and the shortage existing in the prior art. Because the utility model adopts the structures of a catch bolt and a safety nut, the utility model can effectively prevent stealing disassembly. The lathe dog can be simply and conveniently disassembled by a core axle and a structure of an eccentric disk. The utility model has the advantage of simple and safe structure.
Description
The utility model relates to a kind of pipeline jointing clip.
The clip that connects water supply line at present as water supply Glass Steel Tube pipeline clip, generally all adopts standard bolt to connect two half clips up and down.Thereby connecting bolt, nut easily are disassembled or lose; During construction after nut is released, because two half clip obvolvents are tighter, not easily separated.
The purpose of this utility model is: a kind of pipeline jointing clip is provided, makes to be installed fastening safe and reliablely, quick detachable, bolt, nut and clip are inseparable.Thereby overcome the shortcomings and deficiencies that exist in the prior art.
Fig. 1. the utility model structural representation
Fig. 2. left view of the present utility model
Describe the utility model in detail below in conjunction with accompanying drawing: such as Fig. 1, accompanying drawing 2, the clip body is upper and lower two Partly split annular groove. Be respectively equipped with the ear 8 of side opening at front band body 1 two ends, on two ears of front band body 1 End face is provided with packing ring counterbore 5; Lower catch hoop body 11 two ends are respectively equipped with ear 9, and it is respectively equipped with core at ear 9 Axle 7, an end of mandrel 7 connects an eccentric disc 12, and its other end is that six sides (or polygon) nut 13 reaches One eccentric disc 12; Between mandrel 7 and the ear 9 Dogbolt 2 is arranged, Dogbolt 2 one ends and mandrel 7 are hinged, The polished rod diameter on other end top is equal to or greater than major diameter of thread, is rotary with jam nut 3 and packing ring 4 in the middle of it. Between upper and lower clip body, be provided with and open 6. Two eccentric discs 12 are fixedly connected with for symmetry with mandrel 7.
Embodiment: 11 pairs of front band body 1 of the present utility model and lower catch hoop bodies are buckled on the mouth of pipe that needs to be connected, then two retaining bolts 2 of lower catch hoop body 11 are sent into front band body 1 from ear 8 side openings of front band body 1 respectively, make the throw of eccentric of the eccentric disc 12 on the mandrel 7 be in minimum position, in counterbore 5, put steady packing ring 4, at this moment screw jam nut 3, finish the installation of clip.When packing ring 4 was pressed into counterbore, the retaining bolt just can't turn on one's side from front band body 1.When dismounting the utility model, at first jam nut 3 is unscrewed, with spanner rotating screw cap 13 two eccentric discs 12 are rotated then, this moment, the throw of eccentric of eccentric disc 12 increased gradually, the bottom plane that makes eccentric disc 12 promote front band bodies 1, thus the moving front band 1 (also can use ripping bar that front band body 1 is lifted in case of necessity) of sledge makes on the clip body 1 and moves, from two counterbores 5, withdraw from packing ring 4 after, just 2 rollovers of retaining bolt can be broken away from front band 1, open clip at last.
Advantage of the present utility model: 1. adopt Dogbolt and jam nut structure to realize effectively preventing stealing Tear open. 2. adopt mandrel, eccentric disc structure to make the easy removal of clip. The utility model simple in structure, Safe and reliable.
