Abstract
The utility model relates to a corrugated pipe formed by dovetail tenon groove pipes, which not only can effectively increase the strength of a large-diameter corrugated pipe, but also can reduce the weight of the large-diameter corrugated pipe and simultaneously can reduce materials for making the large-diameter corrugated pipe. The corrugated pipe is characterized in that dovetail grooves are arranged in the bottom surfaces of hollow pipes spirally wound on a pipe body of the corrugated pipe; plastic tenons positioned in the dovetail grooves, plastic layers coated on the hollow pipes and the pipe body of the corrugated pipe are in a whole connecting structure. The corrugated pipe has the advantages that (1) the precedent of the corrugated pipe formed by the dovetail tenon groove pipes at single wall is created; (2) not only is the strength of the large-diameter corrugated pipe improved, but also the weight of the large-diameter corrugated pipe is reduced, and simultaneously the consumption of the large-diameter corrugated pipe material is reduced; (3) the dovetail grooves are arranged in the bottom surfaces of the hollow pipes, and a plurality of T-shaped nail-head designs are distributed on the surface, so that the effect of fixing the plastic layers is achieved, the plastic layers and the surfaces of the hollow pipes are firmly connected into a whole, no layering phenomenon in the use of the corrugated pipe is ensured, and the compressive strength of the plastic layers is improved.
Description
Technical field
The utility model relates to a kind ofly can improve heavy caliber bellows intensity effectively, can alleviate heavy caliber bellows weight again, can reduce a kind of bellows that is made up of the dovetail joint barrel of heavy caliber bellows material simultaneously again, belongs to bellows and makes the field.
Background technique
CN201731192U, title " large-caliber double-wall ripple water pipe ", its tube wall constitutes by the inside and outside is two-layer, and its inner tubal wall is smooth, and outer tube wall is trapezoidal corrugated, is provided with stirrup in the cavity between the inside and outside wall, and connects as one at outer wall trapezoidal bottom groove and inwall.Be provided with stirrup in the cavity between this large-caliber double-wall ripple water pipe inside and outside wall; Improved the intensity of water pipe; Compare with the large-diameter steel-plastic waste pipe that generally uses in the existing technology and to have that overall weight is light, cost is low, easy to install and characteristics that cost of production is low.Its deficiency: because the tube wall of bellows is made up of inner and outer wall, the compressive strength of its inwall strengthens through outer wall, and not only weight is big, and raw materials consumption is big, and compressive strength is uneven.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design and a kind ofly can improve heavy caliber bellows intensity effectively, can alleviate heavy caliber bellows weight again, can reduce a kind of bellows that constitutes by the dovetail joint barrel of heavy caliber bellows material simultaneously again.
Design proposal: in order to realize above-mentioned purpose of design.1, bellows is one of technical characteristics of the utility model the design that the plastic tube spiral that has the hollow tube core is formed by stacking.The purpose of doing like this is: it divides body structure with existing double-wall corrugated water pipe by bilayer; Change overall structure into, both escaped to eliminate the inwall in the background technique, integrated the outer wall in the background technique again; Make the ripple tube wall after the integration both have the function of inwall, have the function of outer wall again.Therefore, not only bearing strength is high, low cost of manufacture, and in light weight, greatly reduced raw-material consumption.2, be furnished with the design of a plurality of T staple heads on hollow tube bottom surface dovetail groove and the face, be the utility model technical characteristics two.The purpose of doing like this is: because the hollow tube bottom surface has and is furnished with a plurality of T staple heads on dovetail groove, the face; When molten plastic topped during at T staple head; Its T staple head has not only played restraining function effectively to compound plastic layer above that; And the dovetail groove that is positioned at the hollow tube bottom surface firmly is connected as a single entity hollow tube and bellows pipe shaft, avoided the generation of stratification.
Technological scheme: a kind of bellows that is made up of the dovetail joint barrel, the hollow tube bottom surface that is spirally wound on the bellows pipe shaft has dovetail groove, is positioned at dovetail groove plastics tenon and the plastic layer and the bellows pipe shaft that are coated on the hollow tube are whole linkage structure.
The utility model is compared with background technique, and the one, started the precedent of the bellows that single wall is made up of the dovetail joint barrel; The 2nd, both improved the intensity of heavy caliber bellows, alleviate heavy caliber bellows weight again, reduce the consumption of heavy caliber bellows material simultaneously again; The 3rd, the hollow tube bottom surface has and is furnished with a plurality of T staple head designs on dovetail groove, the face; Both played the effect of fixed plastics layer; Plastic layer and hollow tube face firmly are connected as a single entity, have guaranteed that bellows in use stratification can not take place, and has improved the compressive strength of plastic layer again.
Description of drawings
Fig. 1 is the bellows structure schematic representation that is made up of the dovetail joint barrel.
Fig. 2 is the sectional structure schematic representation of the bellows that is made up of the dovetail joint barrel.
Embodiment
Embodiment 1: with reference to attaching Fig. 1 and 2.A kind of bellows that is made up of the dovetail joint barrel, hollow tube 2 bottom surfaces that are spirally wound on the bellows pipe shaft 1 have dovetail groove 3, are positioned at dovetail groove 3 plastics tenons and the plastic layer 4 that is coated on the hollow tube 2 is whole linkage structure with bellows pipe shaft 1.2 of said hollow tubes are gone up a plurality of T staple heads that distribute, and having to cover on the hollow tube face of T staple head has plastic layer 4 again.Said hollow tube core is metal die or nonmetal tube core.Its making method: hollow tube is through the machine shaping of dovetail groove forming die; As on stripe board, making earlier dovetail groove; Adopt mould shaping to curve hollow tube again; Adopt heavy caliber polyolefin that the claimant makes to twine then to increase pipe production line limit to make hollow tube 2 spirals that bellows pipe shaft 1, limit will have dovetail groove and be entangled on the bellows pipe shaft 1, again molten plastic be compounded on the hollow tube 2 that has dovetail groove, promptly constitute the bellows that constitutes by the dovetail joint barrel.Said hollow tube core wall a plurality of T staple heads that distribute.
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 (3)
1. bellows that is made up of the dovetail joint barrel, it is characterized in that: the hollow tube bottom surface that is spirally wound on the bellows pipe shaft has dovetail groove, is positioned at dovetail groove plastics tenon and the plastic layer and the bellows pipe shaft that are coated on the hollow tube are whole linkage structure.
2. the bellows that is made up of the dovetail joint barrel according to claim 1 is characterized in that: a plurality of T staple heads that distribute on the said hollow tube face have on the hollow tube face of T staple head and are covered with plastic layer.
