Technical field

The present invention relates to flexible hose technical field, specially a kind of enhancing hose flexible.

Background technique

In skills such as some aerospaces, automobile manufacture, bio-pharmaceuticals, medical instrument, the energy, Marine engineering and food productions Art field, it is higher for the requirement of hose, it is desirable that it does not protect hose with good resistance in use not Can be excessive because of extraneous strength, and cause it there is a phenomenon where kink, be crushed and collapse.

And be inside and outside smooth mono-layer tube structure in the flexible hose structure of existing reinforcing, because its material itself has one Hardness is determined, so that the teleflex of this structure, excessive (generally 5-10 times of bending radius, depending on bore) in bending radius When, easily stress and deformation, intensity is lower, and it is during use, more demanding to assembled condition, it is unfavorable for the product of user Upgrading, and in the flexible hose of the number of the applying for a patent CN200980140775.6 reinforcing provided, as shown in Figure 1, flexible soft The periphery of spiral form wire rod on pipe carries out radial reinforcing, when can effectively reinforce its resistance to fight hose bending in Portion collapses and twists together, but due to when it is radially reinforced being that gasket groove is clamped using right angle, so that the bending of hose Angle reduces, its own meeting squeezing tube in curved spout larger angle, so that the bending ability of hose is poor, the scope of application It is lower, as long as and hose effect of the outside by power, hose will be directly passed to, make its unbearable radial pressure, resisted Pressure energy power is poor.

Summary of the invention

(1) the technical issues of solving

The present invention provides a kind of flexible hose of reinforcing, have that bending ability is relatively strong, increases the inside and outside intensity of hose, no Easily-deformable, stability preferably, have the advantages that good anti-pressure ability, be nonabradable solve existing teleflex, be bent When radius is excessive, easily stress and deformation, intensity is lower, during use, more demanding to assembled condition, be unfavorable for using The product up-gradation of person, and in the flexible hose of the number of the applying for a patent CN200980140775.6 reinforcing provided, in flexible hose On the periphery of spiral form wire rod carry out radial reinforcing, its resistance can be reinforced effectively to fight inside when hose bending When collapsing and twist together, but reinforcing since it is radial is that gasket groove is clamped using right angle, so that the bending angle of hose Degree reduces, its own meeting squeezing tube in the biggish angle of curved spout, so that the bending ability of hose is poor, the scope of application It is lower, as long as and hose effect of the outside by power, hose will be directly passed to, make its unbearable radial pressure, resisted The poor problem of pressure energy power.

(2) technical solution

The invention provides the following technical scheme: a kind of enhancing hose flexible, including inner wall road, it is characterised in that: institute The outer surface for stating inner wall road is equipped with flexible jacket layer, and the outer surface of the flexibility jacket layer is equipped with spiral groove.

Preferably, the spiral groove can be set as outwardly projecting equal part continuously trapezoidal dentalation, and its inner wall with Horizontal plane can also be set as inside equal part continuously trapezoidal dentalation at 100 ° of angles, while its inner wall and horizontal plane are at 80 ° Angle.

Preferably, continuously the gap between trapezoidal dentalation is 1~2mm to equal part on the spiral groove.

Preferably, the middle part of the inner wall road is equipped with braid layer, and braid layer can be selected wire sheathing or knit Object braiding layer, while the inner wall of inner wall road is set as smooth structure.

Preferably, PFA plastics or PTFE can be selected in the flexible jacket layer.

(3) beneficial effect

The present invention have it is following the utility model has the advantages that

Enhancing hose flexible, by forming the inner hole of smooth structure to inside, outside has specially designed equal part The setting of trapezoidal continuous helical dentalation, when at the larger open of the trapezium structure of the flexible hose hose upon bending, Available maximum receiving bending range, and the solid bottom of trapezium structure can be right when then making hose in use and bending It is anti-because of Internal Hole Deformation caused by deformation and pressure, rupture and collapse, while the solid section of the trapezium structure can prevent external mill Damage sexuality is destroyed caused by inner hole, and the trapezoidal solid section can enhance hose and resist shape caused by external and internal pressure Become, when hand-held and tool clamps the hose, this trapezoidal continuous helical dentalation of equal part can increase anti-slip performance, finally Structure design for the hose, can Problem of Failure when utmostly preventing hose in alternating bending and frequent operation, have Effect extends the service life of hose, enhances the mechanical performance of the hose, expands application field.
