Abstract
The utility model belongs to pipe technology field, and specifically bellows moulded by a kind of steel.The utility model comprises the plastic tube wall rolled by plastic board/belt spiral, wherein plastic board/belt both sides are overlap, after having rolled, the overlap of plastic board/belt both sides overlaps mutually, projection is provided with outside plastic tube wall, this projection is the inverted trapezoidal shape structure of hollow, between projection, spiral winding has reinforcement steel band, protruding height flushes with the height of reinforcement steel band or lower than the height strengthening steel band, be wound with one deck reinforced layer in the outer felt of the reinforcement steel band rolled and projection, apply bath surface layer outward at reinforced layer.The utility model is reasonable in design, structure is simple, ring stiffness is high, the life-span is long, not slippage between projection and steel band, and split phenomenon without side during manufacture and occur, the ring stiffness of pipeline is desirable and working strength is high.In addition, the utility model is practical, energy-conserving and environment-protective, and this product is adapted at promoting the use of in like product.
Description
Technical field
The utility model belongs to pipe technology field, and specifically bellows moulded by a kind of steel.
Background technique
The steel plastic drain pipe of existing spiral winding normally at the outer winding steel of plastic pipe, and then is formed at steel strip surface coating plastic.For straight wall adds salient point or lath supports between the projection of plastic pipe and steel band, its shortcoming is: quantity of plastics is comparatively wasted, and easily slippage between projection and steel band, side easily occurs during production splits phenomenon, and the ring stiffness of pipeline is undesirable and working strength is low.
Model utility content
The purpose of this utility model is to solve deficiency of the prior art, provides a kind of steel to mould bellows.
The utility model comprises the plastic tube wall rolled by plastic board/belt spiral, wherein plastic board/belt both sides are overlap, after having rolled, the overlap of plastic board/belt both sides overlaps mutually, projection is provided with outside plastic tube wall, this projection is the inverted trapezoidal shape structure of hollow, between projection, spiral winding has reinforcement steel band, protruding height flushes with the height of reinforcement steel band or lower than the height strengthening steel band, be wound with one deck reinforced layer in the outer felt of the reinforcement steel band rolled and projection, apply bath surface layer outward at reinforced layer.
Preferably, described reinforcement steel band extends to form sidepiece downwards after bending from two ends, top, and sidepiece lower end bends laterally and extends to form bottom, and the width bottom it is greater than the width at top.
Preferably, described reinforcement steel band two bottom sides is stuck on the skew wall of protruding both sides.
The utility model is reasonable in design, structure is simple, ring stiffness is high, the life-span is long, not slippage between projection and steel band, and split phenomenon without side during production and occur, the ring stiffness of pipeline is desirable and working strength is high.In addition, the utility model is practical, energy-conserving and environment-protective, and this product is adapted at promoting the use of in like product.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
For making the technical solution of the utility model and feature clearly, below in conjunction with embodiment, the utility model is described in further detail.At this, following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model comprises the plastic tube wall rolled by plastic board/belt 1 spiral, plastic board/belt 1 both sides are wherein overlap, after having rolled, the overlap of plastic board/belt 1 both sides overlaps mutually, protruding 2 are provided with outside plastic tube wall, the inverted trapezoidal shape structure of this projection 2 in hollow, protruding 2 spiral windings have strengthens steel band 3, the height of protruding 2 flushes with the height strengthening steel band 3, one deck reinforced layer 4 is wound with in the outer felt of the reinforcement steel band 3 rolled and protruding 2, applying bath surface layer 5 outward at reinforced layer makes pipeline external surface become smooth surface.
Reinforcement steel band 3 described in the utility model extends to form sidepiece downwards after bending from two ends, top, and sidepiece lower end bends laterally and extends to form bottom, and the width bottom it is greater than the width at top.Described reinforcement steel band 3 two bottom sides is stuck on the skew wall of protruding 2 both sides.Described protruding 2 link into an integrated entity with plastic board 1.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all mode of executions.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
