Abstract

The utility model relates to an air filter core noise reducing pipe. The noise reducing pipe comprises a tubular supporting frame and a tubular face, wherein the tubular supporting frame is defined by a plurality of yarns which are parallelly arranged, and the tubular face is formed by weaving cotton threads and hard wire materials alternately on the supporting frame. The air filter core noise reducing pipe is formed by winding the tubular face formed by weaving the cotton threads and the hard wire materials alternately on the supporting frame on the axial tubular supporting frame formed by arranging the plurality of yarns. The air filter core noise reducing pipe is simple and compact in structure, convenient to manufacture, light in mass, good in overall flexibility, high in density, environment resistant, good in noise reducing effect, long in service life and suitable for car air filter cores.

Description

Air filtering core noise reduction pipe

Technical field

The utility model 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 existing technology air filter core with the pipe cost of production, poor performance, anti-noise weak effect; Deficiencies such as working life is short, it is a kind of simple in structure that the utility model provides, easy to make; 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 utility model 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 beneficial effect of the utility model is: 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,, cooperate the suitable tubulose cylindrical of cotton thread and hard wire rod interval radially to be knitted on the many line yarns and process tubular cover as making an uproar tubular axis by many line yarns to tubular support frame; 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 outer alternating structure of pipe on the line yarn, above-mentioned braiding structure compactness, compactness height; Can effectively absorb noise, anti-acoustic capability is good.

The tubular cover that the noise reduction pipe of the utility model 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, and is easy to make, and 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 the structural representation of the utility model;

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 utility model 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.
