The fastening piece can adopt an external thread pressing sleeve, an internal thread pushing sleeve and a middle push-pressing sleeve, both the external thread pressing sleeve and the middle pushing-pressing sleeve are respectively and axially provided with a through hole in a truncated cone shape, and the half-angles of projection of the external thread pressing sleeve and the middle pushing-pressing sleeve are the same as the half-angle of projection of the jacket; the fastening piece can also adopt a flange pressing sleeve, a screw bolt and a screw nut, the flange pressing sleeve has an internal hole in a truncated cone shape, and the half-angle of projection of the flange pressing sleeve is the same as the half-angle of projection of the jacket. The utility model has the advantages of simple structure, low cost, rapid and convenient installation, firmness, etc., being suitable for connecting industrial and civil gas and liquid pipelines.

Description

The quick pipe joint of pushing chuck self-locking
The utility model relates to the hard tube connection fittings of industry and civil pipeline, the quick pipe joint of especially a kind of pushing chuck self-locking.
Various pipe joints of Xiao Shouing in the market, the complex structure cost height that has, the structural bearing pressure that has is lower, and what have need carry out screw thread to tube head and handle, soldering, and install and waste time and energy.
The purpose of this utility model just provide a kind of simple in structure, cost is low, installation is quick and convenient, using scope pushes the quick pipe joint of chuck self-locking widely.
The purpose of this utility model is adopted realization by following technological scheme:
The quick pipe joint of pushing chuck self-locking is by chuck, sealing gasket, formations such as fastening piece, chuck is a Rotary-table, its outer surface is taper, its half-angle of projection less than 8 ° 32 ', chuck axially has cylindrical hole, cylindrical hole is coaxial with round platform, axial open seam is arranged on the outer surface, fastening piece can adopt outer silk gland, internal thread pushing sleeve and middle pushes against sleeve, outer silk gland outer surface one end is a polygon, the other end has outside thread, outer silk gland axially has the frustoconic shape through hole, its half-angle of projection is identical with chuck, and internal thread pushing sleeve outer surface is a polygon, and the internal thread pushing sleeve axially has coaxial stepped shaft cylindrical hole, its big nose end has internal thread, middle pushes against sleeve outer surface is cylindrical, and it axially has the frustoconic shape through hole, and the half-angle of projection is identical with chuck, during use, an outer silk gland is enclosed within on the chuck, and internal thread pushing sleeve and middle pushes against sleeve are enclosed within on the another chuck, and internal thread pushing sleeve and an outer gland are by being threaded.Fastening piece also can adopt flange gland, bolt, and nut, the endoporus of flange gland are frustoconic shape, and its half-angle of projection is identical with chuck, and the flange gland is enclosed within on the chuck, connects by bolt, nut between the flange gland.
The quick pipe joint structure of pushing chuck self-locking of the present utility model is simple, cost is low, only need tighten screw thread between internal thread pushing sleeve, the outer silk gland or the bolt between the flange gland during use, nut just can link together tube and tube fast, and firm and reliable connection, dismantle also very conveniently, be applicable to industry and being connected of domestic gas, liquid pipeline.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation.
Embodiment 1:
The quick pipe joint of pushing chuck self-locking is by chuck 3, chuck 6, sealing gasket 7, formations such as fastening piece, chuck 3,6 are Rotary-table, its outer surface is taper, the half-angle of projection less than 8 ° 32 ', axially have cylindrical hole, cylindrical hole is coaxial with round platform, axial open seam is arranged on the outer surface, and fastening piece is outer silk gland 2, internal thread pushing sleeve 4 and middle pushes against sleeve 5, outer silk gland 2 outer surfaces one end is a polygon, the other end has outside thread, outer silk gland 2 axially has the frustoconic shape through hole, and its half-angle of projection is identical with chuck, and internal thread pushing sleeve 4 outer surfaces are polygon, it axially has coaxial stepped shaft cylindrical hole, its big nose end has internal thread, and middle pushes against sleeve 5 outer surfaces are cylindrical, and it axially has the frustoconic shape through hole, the half-angle of projection is identical with chuck, outer silk gland 2 is enclosed within on the chuck 3 pushes against sleeve 5 in the middle of being with respectively on the chuck 6, internal thread pushing sleeve 4, internal thread pushing sleeve 4 is threaded with outer silk gland 2, and middle pushes against sleeve 5 is arranged on internal thread pushing sleeve 4, between the outer silk gland 2.
During use, pipe 1, pipe 8 insert respectively in the cylindrical hole of chuck 3, chuck 6, sealing gasket 7 is placed between pipe 1 and pipe 8 end faces, chuck 3 and chuck 6 end faces, outer silk gland 2 and internal thread pushing sleeve 4 are threaded, when screw thread screwed therebetween, middle pushes against sleeve 5 moved towards two pipe joints, chuck 3 and chuck 6 apertures is shunk compress two pipes, two pipes are gone relatively simultaneously, and sealing gasket 7 is compressed.Pipe 1 that compresses and pipe 8 can not become flexible be by the half-angle of projection be used for realize because can produce locking phenomenon less than 8 ° of 32 ' times when the half-angle of projection.
Embodiment 2:
The quick pipe joint of pushing chuck self-locking is by chuck 3, chuck 6, sealing gasket 7, formations such as fastening piece, chuck 3,6 are Rotary-table, its outer surface is taper, the half-angle of projection less than 8 ° 32 ', axially have cylindrical hole, cylindrical hole is coaxial with round platform, axial open seam is arranged on the outer surface, fastening piece is a flange gland 10,11, bolt 9, nut 12, flange gland 10,11 endoporus are frustoconic shape, the half-angle of projection is identical with chuck, flange gland 10,11 are enclosed within chuck 6 respectively, on 3, flange gland 10, pass through bolt 9 between 11, nut 12 connects.
During use, pipe 1,8 inserts respectively in the cylindrical hole of chuck 3,6, sealing gasket 7 is placed between pipe 1 and pipe 8 end faces, chuck 3 and chuck 6 end faces, link to each other by bolt 9, nut 12 between the flange gland 10,11, when tighting a bolt, during nut, flange gland 10,11 compresses two pipes with chuck 3 and the contraction of chuck 6 apertures, two pipes are gone relatively, sealing gasket 7 is compressed.It is that realization is adopted in effect by the half-angle of projection that pipe 1 that compresses and pipe 8 can not become flexible, because can produce locking phenomenon less than 8 ° of 32 ' times when the half-angle of projection.
