Abstract

The invention relates to a noise reduction tube of an air filter element, wherein the noise reduction pipe comprises a tubular support frame formed by a plurality of parallelly-arranged yarns in a circle and a tubular surface formed by knitting cotton threads and hard wire rods at intervals on the tubular support frame. The noise reduction pipe is formed by winding the tubular surface formed by knitting cotton threads and hard wire rods at intervals on the axial tubular support frame formed by arranging a plurality of yarns, has the advantages of simple and compact structure, convenience for manufacturing, light weight, good whole flexibility, high density, environmental resistance, good noise reduction effect and long service life and is suitable for being used in automobile air filter elements.

Description

Air filtering core noise reduction pipe

Technical field

The present invention relates to a kind of noise reduction pipe that is used for air filtering core.

Background technique

The orthodox car air filtering core with pipe adopt polypropylene molding and forming and rubber curing forming spare through clip connected on motor car engine; Rubber curing forming spare needs to customize according to installing space in the car, needs the die sinking tool, and cost of production is high; Assemble loaded down with trivial details, poor for applicability.The existing rubber corrugated pipe that adopts, the rubber corrugated pipe power consumption of polymer processing is high, and cost is high; Intensity is low after bending is installed, and aging quality resistance is poor, in case aging breakage can greatly influence the working life of motor; Can not reduce noise effectively, reclaim the not easy secondary pollution that causes.

Summary of the invention

High in order to solve prior art air filter core with the pipe cost of production, poor performance, the anti-noise weak effect, deficiency such as working life is short the invention provides a kind of simple in structurely, easy to make, and usability is good, the life-span is long, the air filtering core noise reduction pipe that anti-noise is effective.

The technological scheme that the present invention adopts is: a kind of air filtering core noise reduction pipe, its technical characterstic be make an uproar tubular support frame that pipe comprises that the some line yarns that are arranged in parallel surround, by cotton thread and the hard wire rod tubular cover that forms of braiding at interval on tubular support frame.

Outer skin of paint or the plastic-blasting layer of being provided with of the said pipe of making an uproar.

Said line yarn is made up of 1-20 rhizoid yarn.

Said cotton thread is made up of 1-20 rhizoid yarn.

Upper and lower adjacent being knitted to of said cotton thread and hard wire rod is not simultaneously in pipe or the alternating structure outside managing on the line yarn.

Said cotton thread and hard wire rod are symmetry status on the same braiding of tubular support frame cross section.

After adopting above technological scheme; The invention has the beneficial effects as follows: the pipe of making an uproar by many line yarns with spacing shaft to being arranged in tubular support frame, being knitted to many tubular covers on the line yarn by cotton thread and hard wire rod at interval along the tubulose cylindrical and forming; Make an uproar tubular axis to tubular support frame by many line yarns conducts; Cooperate cotton thread and hard wire rod radially to be knitted on the many line yarns at interval and process tubular cover along the tubulose cylindrical; Simple in structure; Easy to make, the pipe light weight of making an uproar, applicability is good; Joint line yarn, cotton thread and hard wire rod characteristic property, make an uproar the pipe overall flexibility good, intensity is high, bending hardness is high, high temperature resistant, low temperature, anti-aging, long service life; Many line yarn interval 1-3mm; Cotton thread and hard wire rod are symmetry status on the same braiding of tubulose cross section; And upper and lower adjacent being knitted to of cotton thread and hard wire rod is not simultaneously in pipe or the alternating structure outside managing on the line yarn; Above-mentioned braiding structure is compact; Compactness is high; Can effectively absorb noise, anti-acoustic capability is good.

The tubular cover that noise reduction pipe of the present invention adopts cotton thread and hard wire rod to weave at interval is wound on the axial tubular supporting frame that many line yarns are arranged in to be formed; It is simple in structure, compact; Easy to make; Light weight, overall flexibility is good, consistency is high; Anti-environment; Excellent noise reduction effect, long service life is fit to car air filtering core and uses.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the schematic top plan view of Fig. 1.

Among the figure: line yarn 1, cotton thread 2, hard wire rod 3, tubular support frame 4, tubular cover 5.

Embodiment

Below in conjunction with accompanying drawing the present invention is described further.

Shown in Fig. 1-2; A kind of air filtering core noise reduction pipe; Become tubular support frame 4 and at interval be woven into tubular cover 5 with hard wire rod 4 along the tubulose cylindricals by cotton thread 2 to form with interval 1-3mm axially-aligned by many line yarns 1, cotton thread 2 and hard wire rod 4 are knitted to many 1 last times of line yarn and are in the pipe and the outer structure that replaces of pipe; Hard wire rod 3 is hard steel wire or high-strength nylon silk or high-strength PET monofilament; The pipe of making an uproar is provided with skin of paint or plastic-blasting layer; Line yarn 1 is made up of 1-20 rhizoid yarn; Cotton thread 2 is made up of 1-20 rhizoid yarn; Upper and lower adjacent being knitted to of cotton thread 2 and hard wire rod 3 is not simultaneously in pipe or the alternating structure outside the pipe on the line yarn, cotton thread 2 and hard wire rod 3 are symmetry status on the same braiding of tubulose cross section.
