Abstract

The utility model relates to a reinforced compound soft pipe twisted with plastic reinforcement bar and screw thread, which comprises a spring structure body and a wrapping layer. The spring structure body takes on the shape of a screw spring. And the surface is wrapped by the wrapping layer. Wrapping layers between the spring thread pitches are connected to form the connecting layer. The outer wall of the compound soft pipe made up of the spring structure body and the wrapping layer takes on the shape of a deep screw. The inner wall is smooth or slightly takes on a screw shape. The reinforced compound soft pipe twisted with plastic reinforcement bar and screw thread has strong rigidity and elasticity, which are both stronger than those of ordinary bare plastic pipe of the same standard. Meanwhile, material is saved as much as possible; a long service life and the recyclable material contribute to the environmental protection and guarantee a wide application field and easy popularization.

Description

Mould the muscle screw thread and twine the enhancing composite soft tube

One, technical field: the utility model relates to a kind of composite soft tube, particularly relates to a kind of muscle screw thread of moulding and twines the enhancing composite soft tube.

Two, background technique: well-known, the application of current tubing is quite at large, its kind is also very various, wherein plastic flexible pipe accounts for sizable ratio, but single material volute or the obvious mechanical property of bellows are too poor, the easy deformation of pressurized, rigidity is not high yet, not enough as the transport agent holding power, so application surface is narrow, also be easy to breakage or fracture.The common muscle pipe mechanical property of moulding is eager to excel in whatever one does more a lot of than single material volute, yet its surface is expended on material quite highly near the plane, and its Young's modulus and hardness are often fixing, and application area is restricted.

Three, model utility content:

The purpose of this utility model:, design a kind of muscle screw thread of moulding and twine the enhancing composite soft tube at the problem that background technique exists.

The technological scheme that the utility model adopted: a kind of muscle screw thread of moulding twines the enhancing composite soft tube, contain spring structure body and coating, the spring structure body is spring-like in the shape of a spiral, be wrapped layer parcel of spring structure surface, coating is connected to form tie layer between the spring pitch, the outer wall of the composite soft tube that spring structure body and coating are formed presents deep spiral shape, inner wall smooth or be little helical.

The described muscle screw thread of moulding twines the enhancing composite soft tube, and spring structure body and coating all use the PVC material to make, and the Young's modulus of spring structure body and coating is different, the elastic modulus E of spring structure body PVC material _SpringGreater than coating PVC elasticity modulus of materials E _Bag

The described muscle screw thread of moulding twines the enhancing composite soft tube, and the cross section of elastic structure is super semicircle, or is half elliptic, or is semicircle, or is square, or is rectangle, or is equilateral triangle, or is circular, or is ellipse, or is rhombus.

Useful good effect of the present utility model:

1. the muscle screw thread of moulding of the present utility model twines the enhancing composite soft tube, and rigidity is big, and elasticity is strong, and compressive strength and elasticity all are higher than the common naked body plastic tube of equal specification.

2. the muscle screw thread of moulding of the present utility model twine to strengthen composite soft tube, economizes on material as far as possible, and weight is half of same specification common plastics tube, long service life, and the protection environment, good result such as economize on resources has been played in recyclable utilization.

3. the muscle screw thread of moulding of the present utility model twines the enhancing composite soft tube, and application is wide, is easy to promotion and implementation.
