Abstract
The utility model relates to a semi-circular metal-tube-shaped open framework for a corrugated pipe. The semi-circular metal-tube-shaped open framework can not only effectively increase the strength of large-diameter corrugated pipes, but also fundamentally improve the elasticity of large-diameter corrugated pipes. The semi-circular metal-tube-shaped open framework comprises a corrugated pipe framework, which is a semi-circular metal-tube-shaped framework, the bottom surface of which is provided at the central portion with through holes along the length direction. The semi-circular metal-tube-shaped open framework has the advantages that firstly, the bottom surface of the semi-circular metal-tube-shaped framework is in surface-to-surface contact with an inner tube, so that not only the pressure on the inner tube is greatly reduced when the semi-circular metal-tube-shaped framework is pressed, but also the semi-circular metal-tube-shaped framework is like an arch-bridge structure with large bearing capacity and the supporting strength and the pressure-bearing capacity of the inner tube are significantly enhanced; and secondly, embedded in the through holes which are provided in the bottom surface of the semi-circular metal-tube-shaped framework along the length direction, plastic wedges guarantee reliable combination of the semi-circular metal-tube-shaped framework and the wall of the inner tube and ensure that layering of the corrugated pipe in use is avoided.
Description
Technical field
The utility model relates to a kind ofly can not only improve heavy caliber bellows intensity effectively, and can make the elasticity of heavy caliber bellows obtain a kind of semicircle metal tubular openings skeleton that is used for bellows that essence improves, and belongs to the bellows skeleton and makes 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 model utility content
Purpose of design: avoid the deficiency in the background technique, design and a kind ofly can not only improve heavy caliber bellows intensity effectively, and can make the elasticity of heavy caliber bellows obtain a kind of semicircle metal tubular openings skeleton that is used for bellows that essence improves.
Design proposal: in order to realize above-mentioned purpose of design.The metal tube cross section is the design of the tubular skeleton of semicircle metal, is the major technique characteristic of the utility model.The purpose of doing like this is: because the tubular skeleton of semicircle metal bottom surface opening is to open along semicircle metal pipe range; Be that suitable long through-hole, both sides are the support edge in the middle of the formed pipe bottom surface; And along long through hole with interior pipe compound tense; The molten plastic that is used to make on the inner tubal wall gets into along forming snap fit in the long through-hole and with suitable long through-hole; Both play the effect of spacing support edge displacement, played the rivet effect of the tubular skeleton of riveted joint semicircle metal again, played the effect of pipe intensity in strengthening simultaneously again; Secondly, the tubular skeleton of semicircle metal because the tubular skeleton of semicircle metal is neither outwards taken off and moved, can inwardly not contract yet and move when receiving the external force extruding, has guaranteed reliably compound between tubular skeleton of semicircle metal and inner tubal wall.
Technological scheme 1: a kind of semicircle metal tubular openings skeleton that is used for bellows, it comprises the bellows skeleton, said bellows skeleton is the tubular skeleton of semicircle metal and middle part, the tubular skeleton of semicircle metal bottom surface has through hole along length.
The utility model is compared with background technique; The one, the tubular skeleton of semicircle metal bottom surface contacts with the inner tube surface face; When making the tubular skeleton pressurized of semicircle metal, not only greatly alleviated the pressure of internal pipe, and the tubular skeleton of semicircle metal is just as the arch bridge structure; Bearing capacity is big, has greatly improved interior pipe support strength and bearing capacity; The 2nd, because the tubular skeleton of semicircle metal bottom surface is embedded with the plastics wedge along the long through hole of opening, this plastics wedge has been guaranteed the reliable connection between tubular skeleton of semicircle metal and inner tubal wall, has guaranteed that bellows in use stratification can not take place.
Description of drawings
Fig. 1 is the structural representation that is used for the semicircle metal tubular openings skeleton of bellows.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of semicircle metal tubular openings skeleton that is used for bellows, it comprises bellows skeleton 1, said bellows skeleton 1 is the tubular skeleton of semicircle metal and middle part, the tubular skeleton of semicircle metal bottom surface has through hole 2 along length.Middle part, said semicircle metal tube bottom surface is little 20 millimeters along long through-hole 2 width, and its preparation process 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, appointed Ke to be no more than the combination of the utility model mentality of designing the restriction of the utility model mentality of designing; Increase and modification, all fall in the protection domain of the utility model.
Claims (2)
1. semicircle metal tubular openings skeleton that is used for bellows, it comprises bellows skeleton (1), it is characterized in that: said bellows skeleton (1) is the tubular skeleton of semicircle metal and middle part, the tubular skeleton of semicircle metal bottom surface along the long through hole (2) that has.
2. the semicircle metal tubular openings skeleton that is used for bellows according to claim 1 is characterized in that: middle part, said semicircle metal tube bottom surface is little 20 millimeters along long through-hole (2) width.
