Abstract
The utility model relates to a kind of 3S metallic hose on heavy-duty car, comprise the metal mutual sleeve tube of adjacent, described metal mutual sleeve tube is formed by metal tape coiling, the longitudinal section of described metal tape is one and is folded in straight S shape the connecting body that another is hook S shape, one end of its band hook portion is set to the first hook, its the other end is portion always, and its folded part is the second hook; The first described hook there is the first rotating part, the first rotating part has the first insertion part; The second described hook there is the second rotating part, the second rotating part has the second insertion part; Its beneficial effect is: 1, because its second hook is folded part, be made up of two layers of wall, and therefore its intensity increases; 2, improve the high pressure of metal mutual sleeve tube, seal request and enhance circumferential strength, extending metal mutual sleeve tube long service life.
Description
Technical field
The utility model relates to a kind of 3S metallic hose on heavy-duty car.
Background technique
Metallic hose can free bend, the performance such as ageing-resistant and corrosion-resistant because having, and is widely used in automobile, machinery, chemical industry, aviation, shipbuilding and building field.
At present conventional metallic hose, is shown in Fig. 1, and it comprises adjacent metal and overlaps tube coupling mutually and formed by metal tape coiling, and the longitudinal section of each mutual cover tube coupling is in ∽ shape, and two ends in longitudinal section are equipped with a hook, and hook is provided with transfer part, and rotating part is provided with insertion part; The mutual fit fastening of hook on adjacent mutual cover tube coupling, its insertion part and rotating part insert mutually, be adjacent to cell wall and the insertion part of adjacent rotating part, thus form the metal sleeve extended.This metallic hose also exists under long term high temperature service condition in using as heavy duty automobile exhaust tube, hook portion there will be the problem that structural strength declines, because adjacent mutual cover tube coupling connects, its insertion part only has three layers of faying surface, by peripheral force effect, the problem that tightness weakens easily occurs.
Model utility content
In order to overcome the structural strength that existing metallic hose exists, by peripheral force effect, the problem that tightness weakens easily occurs, the utility model provides a kind of 3S metallic hose.
The technical solution adopted in the utility model is: a kind of 3S metallic hose on heavy-duty car, it is characterized in that: the metal mutual sleeve tube comprising adjacent, described metal mutual sleeve tube is formed by metal tape coiling.
Further, for making the intensity of many one decks faying surface and increase the second hook portion between the metal mutual sleeve tube after coiling, the longitudinal section of described metal tape is one and is folded in straight S shape the connecting body that another is hook S shape, one end of its band hook portion is set to the first hook, its the other end is portion always, and its folded part is the second hook; The first described hook there is the first rotating part, the first rotating part has the first insertion part; The second described hook there is the second rotating part, the second rotating part has the second insertion part.
Further, for making more to fit between the metal mutual sleeve tube after coiling, the mutual fit fastening of the second hook on the first hook on described metal tape and adjacent metal tape, the cell wall of the second rotating part is inserted, is adjacent in first insertion part, the cell wall of the first rotating part is inserted, is adjacent in the second described insertion part, and the straight portion on described metal tape is adjacent to mutually with the second hook outer side wall of adjacent metal tape.
Further, for ensureing corrosion resistant, resistance to embroidery in metal mutual sleeve tube joint Long-Time Service, the material of described metal mutual sleeve tube joint can adopt stainless steel belt or Galvanized Steel Strip.
Beneficial effect of the present invention is embodied in: 1, because its second hook is folded part, be made up of two layers of wall, and therefore its intensity increases; 2, due to its joint increase portion always, in pipe, high-temperature gas and pipe are interlinked to the outside, need through four layers of faying surface, and surface of contact of fitting in the middle part of straight portion and adjacent metal tape is larger, therefore difficulty is larger, which improves the high pressure of metal mutual sleeve tube, seal request and enhance circumferential strength, extending metal mutual sleeve tube long service life, can be used for the outlet pipe of heavy-duty car.
Accompanying drawing explanation
Fig. 1 is the vertical section structure schematic diagram of common metal flexible pipe;
Fig. 2 is plan view of the present utility model;
Fig. 3 is longitudinal section of the present utility model schematic diagram;
Fig. 4 is the longitudinal section schematic diagram of metal tape of the present utility model.
Embodiment
Referring to figs. 2 to Fig. 4, a kind of 3S metallic hose on heavy-duty car, is characterized in that: the metal mutual sleeve tube comprising adjacent, described metal mutual sleeve tube is formed by metal tape 1 coiling.
Further, for making the intensity of many one decks faying surface and increase the second hook portion between the metal mutual sleeve tube after coiling, the longitudinal section of described metal tape 1 is one and is folded in straight S shape the connecting body that another is hook S shape, its one end is set to the first hook 11, its the other end is portion 12 always, and its folded part is the second hook 13; The first described hook 11 has on the first rotating part 14, first rotating part and have the first insertion part 15; The second described hook 13 has on the second rotating part 16, second rotating part 16 and have the second insertion part 17.
Further, for making more to fit between the metal mutual sleeve tube after coiling, the first hook 11 on described metal tape 1 and the fit fastening mutually of the second hook 13 on adjacent metal tape 1, first insertion part 15 is inserted, be adjacent to the cell wall of the second rotating part 16, the cell wall of the first rotating part 16 is inserted, is adjacent in the second described insertion part 17, and the straight portion 12 on described metal tape is adjacent to mutually with the outer side wall 18 of the second hook 13 of adjacent metal tape 1.
Further, for ensureing corrosion resistant, resistance to embroidery in metal mutual sleeve tube joint Long-Time Service, the material of described metal mutual sleeve tube joint can adopt stainless steel belt or Galvanized Steel Strip.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And these belong to spirit institute's apparent change of extending out of the present utility model or change and are still among protection domain of the present utility model.
