Background

As shown in fig. 1, a common hollow-wall winding pipe is manufactured by extruding materials to a machine head and a mouth mold by an extruder, changing the size of the mouth mold to manufacture winding square pipes 10 with various specifications, cooling and forming, then winding the winding square pipes by the winder, extruding viscose 20 by the viscose extruder to bond the two square pipes, and cooling again to form a product. The extrusion shape of the die of the common head die is in a shape of a Chinese character 'kou', when a winding machine winds, the viscose extruder extrudes the viscose 20 between the two square tubes 10, and the viscose 20 and the square tubes 10 are flattened by the pinch roller. However, in the prior art, the square tube has narrow dimension and width, the production speed is slow, the spiral distance of the glue is short, the glue consumption is large, and the manufacturing cost is high. Because the square tube is in a shape of a Chinese character kou, the width and the thickness of the square tube are relatively wide, and the hand feeling and the ring rigidity are influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defect of at least one of current cavity winding pipe, providing an interior reinforcing cavity winding pipe.

Specifically, the utility model provides an interior reinforcing cavity winding pipe, glue including first side pipe and connection, wherein, be provided with at least one first stiffening rib in the first side pipe, first side pipe is through spiral winding and warp the connection glue bonds as an organic wholely, forms winding pipe tubular product.

Optionally, the first reinforcing rib divides the pipe hole in the first square pipe into at least two sub-pipe holes;

at least two of the daughter pipe holes are sequentially arranged along the axial direction of the inner reinforced hollow winding pipe.

Optionally, the number of the first reinforcing ribs is two, and the two first reinforcing ribs are uniformly distributed in the first square tube.

Optionally, the first square pipe and the first reinforcing rib are integrally extruded.

Optionally, interior reinforcing cavity winding pipe still includes second side pipe, second side pipe set up in one side of first side pipe, and carry out the spiral winding in step, after the spiral winding, the pipeline section of first side pipe with the pipeline section of second side pipe is followed the axial direction of interior reinforcing cavity winding pipe sets gradually.

Optionally, at least one second reinforcing rib is arranged in the second square tube.

Optionally, the cross-sectional area of the tube bore in the first square tube is larger than the cross-sectional area of the tube bore in the second square tube.

Optionally, the cross-sectional area of the tube bore in the second square tube is 2/5 to 3/5 of the cross-sectional area of the tube bore in the first square tube.

The embodiment of the utility model provides a following technological effect has: because the first reinforcing rib is arranged in the first square tube, the first square tube can obtain more supporting points, so that the pressure bearing capacity is improved, namely the ring rigidity is improved. And because the existence of first stiffening rib, can make the width grow of first side's pipe, the extrusion capacity grow, production speed obtains improving, and viscose spiral distance grow reduces the viscose quantity simultaneously, the manufacturing cost that significantly reduces.

Further, the first square pipe and the existing square pipe can be combined for use so as to meet various requirements of hollow winding pipes.

The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.
