Description
Technical field
The present invention relates to Vacuum Field, be specifically related to a kind of novel evacuated supplementary flexible pipe.
Background technique
On-the-spot in the manufacturing operation of enterprise, some are often had to use the equipment of gas or liquid-working-medium, the conveyance conduit of medium adopts flexible pipe, all kinds of height, it is a kind of commonplace phenomenon that the connection of low-pressure hose uses, the use that particularly vacuum hose is more many is now in the middle of our daily life, the universal of vacuum material also makes such situation more many, so vacuum supplements the joint of flexible pipe is also more difficult something, especially with oxygen, combustion gas, pressurized air and nitrogen, hydrogen, argon, carbon dioxides etc. are that the hot working unit of working medium is all the more so.The Placement of flexible pipe generally all adopts iron wire to bundle or pipe collar connects, the common feature of these three kinds of Placements makes flexible pipe that is tied or banding produce internal withdraw type extrusion-deformation, by internal surface or the inner tube internal surface of flexible pipe, realize sealing and being connected with the anti-slip frictional resistance between connecting tube core outer surface, its attachment force only results from pipe internal surface, when not using special tooling, instrument, its join strength, sealing all not easily ensure, easy leakage, even come off, and charge and discharge operations is loaded down with trivial details, effort.
Summary of the invention
Technical problem solved by the invention can realize by the following technical solutions: a kind of novel evacuated supplementary flexible pipe, comprise hookah bodies to be made up of hard metal, described flexible pipe is provided with joint in end, described hose coupling is by bolt, tightening nut, nut of living forms, described bolt is provided with cylindric bolt head and is provided with thread section above, to supplement the internal diameter of flexible pipe corresponding with being connected vacuum for the external diameter of described thread section, the center portion of described bolt is provided with through hole, and bolt body is a frustoconic shape, one end that described frustoconic shape bolt body radius is large is connected with socket cap, described tightening nut inner side surface is provided with internal thread and the screw thread of described internal thread and bolt matches, described socket cap be provided with nut alive away from bolt body one end, also internal thread is provided with and bolt head matches inside described nut alive.
Preferably, the sectional shape of described bolt hole has two kinds, and wherein corresponding bolt body part is circular hole, and corresponding bolt head part is regular polygon driving hole.
Preferably, the endoporus of described bolt head part is regular hexagon driving hole and is provided with supporting spanner.
Preferably, described tightening nut lower end is provided with one section of extension, and described extension part is also cylindrical body and radius is identical with being connected flexible pipe radius, and described extending part inner side surface is smooth surface.
Preferably, the end of described bolt head is provided with ladder seam, and described ladder seam is provided with round rubber seal ring.
Beneficial manner: compared with prior art, the novel evacuated supplementary flexible pipe of one that the present invention adopts comprises hookah bodies and is made up of hard metal, described flexible pipe is provided with joint in end, and described hose coupling is made up of bolt, tightening nut, nut of living, and uses the hose coupling of such structure, join strength is high, good seal performance, not easily leak, more difficult drop-off, and loading, unloading are without the need to by other instrument, easy and simple to handle, quick, laborsaving, can complete by hand.
accompanying drawing illustrates:
Fig. 1 is the novel evacuated supplementary flexible pipe of one of the present invention.
Fig. 2 is the side view of Fig. 1.
Wherein: 1-a kind of novel evacuated supplementary flexible pipe, 2-joint, 3-bolt, 4-tightening nut, 5-nut of living, 6-thread section, 7-through hole, 8-extend, 9-ladder seam, 10-bolt head.
Embodiment
A kind of novel evacuated supplementary flexible pipe 1, comprise hookah bodies 1 to be made up of hard metal, described flexible pipe is provided with joint 2 in end, described hose coupling 2 is by bolt 3, tightening nut 4, nut 5 of living forms, described bolt 3 is provided with cylindric bolt head 10 and is provided with thread section 6 above, to supplement the internal diameter of flexible pipe 1 corresponding with being connected vacuum for the external diameter of described thread section 6, the center portion of described bolt 3 is provided with through hole 7, and bolt body is a frustoconic shape, one end that described frustoconic shape bolt 3 body radius is large is connected with socket cap, described tightening nut 4 inner side surface is provided with internal thread and the screw thread of described internal thread and bolt 3 matches, described socket cap be provided with nut 5 alive away from bolt body 3 one end, also internal thread is provided with and bolt head 10 matches inside described nut alive 5, because the use that present vacuum hose is more many in the middle of present operating process is in the middle of our daily life, the universal of vacuum material also makes such situation more many, so vacuum supplements the joint of flexible pipe is also more difficult something, so just very large degree have impact on the progress of construction and some factor of safety of other each side, in the present embodiment, comprise hookah bodies 1 by the novel evacuated supplementary flexible pipe of one adopted to be made up of hard metal, described flexible pipe 1 is provided with joint 2 in end, described hose coupling 1 is by bolt 3, tightening nut 4, nut 5 of living forms, use the hose coupling 2 of such structure, join strength is high, good seal performance, not easily leak, more difficult drop-off, and dress, unload without the need to by other instrument, easy and simple to handle, fast, laborsaving, can complete by hand, first bolt 3 is joined inside flexible pipe by the effect of expanding when joint, then outside itself and bolt body are carried out fastening with tightening nut 4, then work nut 5 is connected with bolt head 10, whole joint part is so just made to can be good at being fixed together.
It should be noted that, the sectional shape of described bolt 3 through hole has two kinds, wherein corresponding bolt body part is circular hole, corresponding bolt head part is regular polygon driving hole, the endoporus of described bolt head 10 part is regular hexagon driving hole and is provided with supporting spanner, because bolt head 10 is connected with bolt body, and be all through screw thread be connected with other two tightening nuts 4 and nut 5 of living, because know according to general knowledge, when screw threads for fastening or need very large torque when untiing, this just needs bolt to fix, in the present embodiment, the endoporus of bolt head 10 part is regular hexagon driving hole and is provided with supporting spanner, this makes it possible to well ensure that middle bolt is different, make other two can facilitate fastening and untie.
Described on base, described tightening nut 4 lower end is provided with one section and extends 8, described extension 8 is also cylindrical body and radius is identical with being connected flexible pipe 1 radius, described extending part 8 inner side surface is provided with ladder seam 9 for the end of bolt head described in smooth surface, described ladder seam 9 is provided with round rubber seal ring, when in use because ensure that tightening nut 4 and bolt 3 have enough frictional force, so be provided with one section of extension 8 in tightening nut 4 lower end, this also well solves this problem, and to be provided with round rubber seal ring on ladder seam 9 be to make connection more be added with seal, prevent it from producing situation about revealing.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.All new in this practicality, be all included in the invention within the scope of type or being equal to the change in scope of the present invention.
