Abstract
The utility model discloses a kind of sound insulation aluminium foil hoses, including aluminium foil strip and the spiral wire coated by aluminium foil strip, sound-proof material is coated on the outside of the aluminium foil strip, it further include several interface sections along hose length directional spreding, the interface section includes the fixed strip extended along hose circumferencial direction, there are two ends for the fixed strip tool, the utility model fixed strip pre-buried annular and that insertion annular groove can be compressed in hose, when band tightens hose end, fixed strip can be directly embedded into annular groove, and hose is fixed.
Description
Technical field
The utility model belongs to aluminium foil hose field, more specifically to a kind of sound insulation aluminium foil hose.
Background technique
Aluminium foil hose is with spiral wire for support, has aluminium foil strip cladding in the circle surfaces externally and internally that spiral wire is formed,
And spiral wire is lived by the gluing in aluminium foil strip, entire aluminium foil hose can arbitrarily be bent compression, easy to use.
And the aluminium foil hose with soundproof effect is the right cladding sound-proof material of outer layer in aluminium foil, such as foamed cotton or other forms
Porous cotton, although soundproof effect can be played, when the air port with ventilation equipment is connect, the air port of ventilation equipment has a plurality of
Then the annular groove of circle distribution is tied up on the outside usually by the end sleeve of hose at the air port of ventilation equipment with band
Tightly, it is expected that hose can be embedded in annular groove that hose is fixed, but there is the steel wire of spiral in the inside of hose, steel wire exists
It during being tightened by band, can not be embedded in annular groove, and due to the surface that it can only be attached to annular groove, be formed smaller
Contact area is easily slided, and especially for sound insulation hose, its thickness is thicker, and band can not act directly on annular groove
Place is easy to happen and leaks out or even break-off.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of pre-buried annular in hose and can compress insertion
The fixed strip of annular groove, when band tightens hose end, fixed strip can be directly embedded into annular groove, to hose into
The fixed sound insulation aluminium foil hose of row.
To achieve the above object, the utility model provides following technical solution: a kind of sound insulation aluminium foil hose, including aluminium foil
Band and the spiral wire coated by aluminium foil strip, are coated with sound-proof material on the outside of the aluminium foil strip, further include several along hose length
The interface section of directional spreding, the interface section include the fixed strip extended along hose circumferencial direction, and there are two the fixed strip tools
End.
The further fixed strip is coated on interior by aluminium foil strip.
The further fixed strip is between aluminium foil strip and sound-proof material.
The further fixed strip is staggered with spiral wire, and provided circumferentially about has several fixed strips at one.
The further fixed strip is annular in shape, and compression opening is formed between two ends.
Compared with prior art, the utility model has the beneficial effects that add fixed strip in hose, by the end of hose
When portion is fixed on the air port of ventilation equipment, hose outer surface is tightened by band or other modes, and fixed strip therein and wind
Annular groove on mouth is in the same direction, and fixed strip will be embedded in annular groove, realizes to the end of hose and effectively fixes, even if in wind speed
When larger with air quantity, hose and ventilation equipment will not be made to be detached from.
Detailed description of the invention
Fig. 1 is a kind of cross section view of sound insulation aluminium foil hose of the utility model；
Fig. 2 is the first structural schematic diagram of fixed strip in the utility model；
Fig. 3 is second of structural schematic diagram of fixed strip in the utility model.
Appended drawing reference: 1, sound-proof material；2, spiral wire；3, aluminium foil strip；4, compression opening；5, fixed strip；6, interface section.
Specific embodiment
A kind of embodiment of sound insulation aluminium foil hose of the utility model is described further referring to figs. 1 to Fig. 3.
A kind of sound insulation aluminium foil hose, including aluminium foil strip 3 and the spiral wire 2 coated by aluminium foil strip 3, the aluminium foil strip 3
Outside is coated with sound-proof material 1, further includes several interface sections 6 along hose length directional spreding, and interface section 6 is for setting with ventilation
Standby one section of region being attached, the interface section 6 include the fixed strip 5 extended along hose circumferencial direction, and the fixed strip 5 has
There are two end, there are two ends to guarantee that it can be compressed when being squeezed along the center of circle direction of place circle for the tool of fixed strip 5,
Prevent inclination and 2 similar state of spiral wire.
In the present embodiment the position of fixed strip 5 can between two layers of aluminium foil strip 3, or aluminium foil strip 3 and sound-proof material 1 it
Between.
The structure of fixed strip 5 can be distributed in same circumference for multisection type in the present embodiment, i.e., the described fixed strip 5 and spiral steel
Silk 2 is staggered, and one it is provided circumferentially about have several fixed strips 5, wherein each preferred three fixation provided circumferentially about
Item 5 is distributed between spiral wire 2 as shown in Fig. 2, 5 length of fixed strip is shorter at this time, is not intersected with spiral wire 2,
When being fixed with ventilation equipment air port, fixed strip 5 can be directly embedded into annular groove, without considering the state of spiral wire 2.
Wherein the structure of fixed strip 5 can also be state as shown in Figure 3, i.e., the described fixed strip 5 is annular in shape, and two ends
Between form compression opening 4, the fixed strip 5 of such structure needs interlock with spiral wire 2, and preferred fixed strip 5 is in spiral shell
The inner ring of steel wire 2 is revolved, i.e. spiral wire 2 is pressed in the upper surface of fixed strip 5, and when the air port with ventilation equipment is connect, annular consolidates
Determine item 5 and compression is able to carry out by compression opening 4, in the annular groove in then whole insertion air port, fixation.
The mode of both the above fixed strip 5 can be still directly embedded into when with sound-proof material 1, although thicker
In annular groove, air hose is carried out effectively fixed.
The present embodiment is preferably distributed multiple fixed strips 5 in each interface section 6 on the axis of air hose, as shown in Figure 1,
When fixed strip 5 is annular in shape, 4 direction of compression opening of each fixed strip 5 is mutually staggered.
Prompt iron plate or poster or other prompt sides can be also arranged in the present embodiment at the outer surface corresponding interface section 6 of air hose
Formula can be intercepted directly in the air hose for needing to intercept partial-length in use, user can directly intercept referring to this prompt
Subsequent connection is facilitated to use to interface section 6.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
