Description
Technical field
The utility model relates to the support technology field of pipe, cable or pillar, and more particularly, it relates to a kind of metallic hose with double screws.
Background technique
Common metallic hose is divided into single button Guan Yushuan button pipe, and the formation of metallic hose is all be wound around by metal bar and formed.
At present, application number be 201220697137.3 Chinese patent disclose a kind of metallic hose with double screws structure, metal tube is entwined by metal bar, the both sides of metal bar form interior crimping and outer crimping respectively, the cross section of the type of falling S that formed, together with adjacent interior crimping snaps over outer crimping, the thickness of this metal bar is 0.16-0.2mm; Wherein the face width of metal tube is 2.5mm to the maximum, and furrow width is 1mm to the maximum, and the width of the width of interior crimping and outer crimping is 0.7-1mm.
This metallic hose with double screws structure is by strengthening the width of crimping and outer crimping in metal tube metal bar to improve the tensile strength of metal tube, the face width of metal tube and furrow width have been carried out the adjustment of optimum size ratio simultaneously, make the winding number of turns of metal tube more, its elasticity is better, but: because the shape restriction of the interior crimping of this metallic hose with double screws structure and outer crimping, activity between interior crimping and outer crimping is limited, greatly limit the curved space of metallic hose with double screws, also have impact on the elastic performance of metallic hose with double screws.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of elastic performance, bending properties better metallic hose with double screws.
For achieving the above object, the utility model provides following technological scheme:
A kind of metallic hose with double screws, comprise metal tube, described metal tube is formed by the mutual hasp of some metal bars, described metal bar is divided into interior crimping and outer crimping, spring section is connected with between described interior crimping and outer crimping, after described interior crimping and outer crimping form metal tube along the mutual hasp of metal tube axial direction, spring section is in forming some elastic spaces along on metal tube axial direction.
Setting like this, in utilizing compared to tradition, crimping and outer crimping cooperatively interact the metallic hose with double screws of activity, in this programme, there is between interior crimping and outer crimping a spring section, spring section is directly connected with interior crimping and outer crimping, without the need to separately increasing complexity independently parts, interconnective relation is formed by spring section, spring section has elasticity, to take advantage of a situation after hose bending deformation, to coordinate with it, spring section has good elasticity from rising, automatically recover after deformation, improve elastic performance and the flexion torsion of flexible pipe.
Further setting: " U " type limit of crimping and outer crimping in described spring section is integrated and connects.
Setting like this, spring section is " U " type structure, has the side that two gaps are arranged, has curved section, can support two sides between side, is never formed and has flexible spring section.
Further setting: the two ends of " U " type of described spring section is provided with the first flanging toward flanging and the second flanging, described interior crimping is positioned on the first flanging, and described outer crimping is positioned on the second flanging.
Setting like this, the elasticity direction of spring section is the axial direction of flexible pipe, and the first flanging and the second flanging are by spring section and interior crimping or outer crimping mutual dislocation, and that avoids interior crimping and outer crimping influence elastane portion suppresses space.
Further setting: described interior crimping has " U " type and buckles, outer crimping has one and to cooperatively interact the inverse u shape button of hasp with interior crimping.
Setting like this, interior crimping and outer crimping adopt " U " type to buckle and cooperatively interact, and compact structure is more firm.
As preferably, the width of described interior crimping is equal with the width of outer crimping, and equal with the width of the groove of interior crimping, outer crimping.
Setting like this, after interior crimping and outer crimping are fixed, mutually conflicts fixing, can not be moved even at the cost of one's life, fixing more firm.
Further setting: bending towards inner radius of " U " the type limit of described spring section, described interior crimping and outer crimping are positioned at the outer radius of metal tube.
Setting like this, spring section is near the inner radius of flexible pipe, and interior crimping and outer crimping interfix cooperation, and be positioned at the outer radius of flexible pipe, position is arranged rationally, makes full use of space.
As preferably, the minimum diameter of described metal tube is 6mm, and external diameter is 10.8mm, and thickness of strips is 0.13mm.
Setting like this, spring section has certain curved space and elastic space, but when internal diameter diminishes, the value at other positions is corresponding also can diminish, and causes the dual-side on " U " type limit of spring section mutually to be conflicted, does not have elastic space.
As preferably, the maximum inner diameter of described metal tube is 30mm, and external diameter is 40.3mm, and thickness of strips is 0.25mm.
Setting like this, when internal diameter becomes large, causes the dual-side excesssive gap on " U " type limit of spring section long, makes the effect of following the string of " U " type structure, therefore limits internal diameter maximum value.
