Abstract
The utility model relates to a hole circle type spiral-spring pipe framework for manufacturing corrugated pipes and the hole circle type spiral-spring pipe framework can effectively improve the strength of the large-caliber corrugated pipe and fundamentally improve elasticity of the large-caliber corrugated pipe. The spiral spring pipe framework comprises a spiral-spring pipe. A plurality of wedge nail holes are punched in the surface of the spiral-spring pipe and hole edges of wedge nail holes form hole circles. The framework has the advantages in that by means of the design of the hole circle type spiral-spring pipe framework, the integral compressive and bearing strength of the corrugated pipe is greatly improved, stretching change of the corrugated pipe caused by temperature is restricted to the maximum extent, and adaptability of the corrugated pipe to different temperatures is further improved, so that disconnection and fluid leakage of a butt joint of the corrugated pipe are avoided.
Description
Technical field
The utility model relates to a kind ofly can not only improve heavy caliber bellows intensity effectively, and can make that the elasticity of heavy caliber bellows obtains that essence improves a kind ofly be used for the hole circle formula snake-spring tube skeleton that bellows is made, belong to bellows and make the field.
Background technique
CN201078525Y, title " socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe ", it is used to solve the problem of easy seepage of steel band reinforced polyethylene spiral ripple pipe connection interface and poor reliability.Socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe; Be the metal frame that twines to be fixed on the inner layer polyethylene with outer layer polyethylene; Particularly an end of bellows is provided with socket, and the other end of bellows is provided with bellmouth, imbeds a circle electric heating element on the bellmouth inwall and forms.Adopt this socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe, can be widely used in the connection construction of plastic tube.Its deficiency: the one, metal frame is the outer structure of taking off, and what form with inner layer polyethylene is that the line face contact, rather than face contacts; Not only plyability is poor; And under the effect of external force, metal frame is prone to take off mobile outward, causes inner layer polyethylene is destroyed; The quality of direct shadow pipe matter, even cause inner layer polyethylene damaged; The 2nd, support strength is low, because metal frame is the outer structure of taking off, outwards move its metal frame both sides of external pressure, not only causes the layering of metal frame and inner layer polyethylene, and cause the direct reduction of inner layer polyethylene intensity; The 3rd, because outer layer polyethylene and metal frame are two kinds of material different, had nothing in common with each other by its coefficient that expands with heat and contract with cold of Influence of Temperature, therefore stratification in use takes place inevitably, cause bellows intensity sharply to descend, bellows caves in.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design a kind of heavy caliber bellows that can not only improve effectively and strengthen, and can make the elasticity of heavy caliber bellows obtain a kind of hole circle formula snake-spring tube skeleton that is used for the bellows making that essence improves.
Design proposal: in order to realize above-mentioned purpose of design.Dashing on the snake-spring tube face has a plurality of wedges nail hole and wedge nail hole, hole along the design that forms the hole circle, is the major technique characteristic of the utility model.The purpose of doing like this is: when molten plastic and snake-spring tube compound tense; The plastics of its fusion externally effect of pressure get into wedge nail hole formation wedge nail down; This wedge nail firmly is connected as a single entity compound snake-spring tube and interior pipe on inner pipe; And put the molten plastic layer on the snake-spring tube face after the cooling with the snake-spring tube outer wall on a plurality of by combining together along forming the hole circle in wedge nail hole, hole, its hole is enclosed just as the boss stiffening rib, makes the intensity that is compounded in the plastic layer on the snake-spring tube outer wall obtain the raising of essence.
Technological scheme: formula snake-spring tube skeleton is enclosed in a kind of hole that is used for the bellows making, and it comprises snake-spring tube, and dashing on the said snake-spring tube face has a plurality of wedges nail hole and wedge nail hole, hole to enclose along the formation hole.
The utility model is compared with background technique; The design of hole circle formula snake-spring tube skeleton; Entire compression, the bearing strength of bellows have not only greatly been improved; And retrained temperature to greatest extent to the extending amount variation that bellows caused, make bellows obtain further raising, thereby avoided the generation that made bellows joint is thrown off, fluid runs the leakage phenomenon the adaptability of different temperatures.
Description of drawings
Fig. 1 is the cross section structure schematic representation of the multiple plastic layer of pipe inside and outside wall.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of hole circle formula snake-spring tube skeleton that is used for the bellows making, it comprises snake-spring tube 1,1 of said snake-spring tube is gone up to dash has a plurality of wedges nail hole 2 and wedge to follow closely 2 holes, hole along forming the hole circle.Said snake-spring tube adopts steel band to make or adopts aluminium strip to make.Its making method is an existing technology, is not described herein at this.
What need understand is: the detailed text description though above-mentioned mentality of designing to the utility model is contrasted; But these text descriptions; Just the simple text of the utility model mentality of designing is described, rather than to the restriction of the utility model mentality of designing, any combination that does not exceed the utility model mentality of designing; Increase and modification, all fall in the protection domain of the utility model.
Claims (1)
1. one kind is used for the hole circle formula snake-spring tube skeleton that bellows is made, and it comprises snake-spring tube ⑴, it is characterized in that: dashing on the said snake-spring tube ⑴ face has a plurality of wedge nail hole ⑵ and wedge nail ⑵ hole, hole along forming the hole circle.
