SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model discloses a water-conveying plastic-coated hose which can prevent the hose from being damaged when being stacked or folded.

The technical scheme of the utility model is as follows: water delivery plastic-coated hose, inlayer are equipped with cladding material layer, compressive layer, outer plastic layer, buffer layer, inoxidizing coating and wearing layer outward in proper order, and the cladding material layer and the outer plastic layer through interlock pencil and both sides are connected on the compressive layer, and the buffer layer both sides are equipped with arch and arcwall face respectively, are equipped with the clearance between the arch.

Further, be equipped with the arch on the buffer layer is close to the one side lateral wall of inlayer, be equipped with the clearance between the arch, the clearance is outside concave surface, and the arch includes cylinder and arc surface, and the arc surface is located the top of cylinder.

Further, the buffer layer is located in proper order to the arcwall face one side far away from the inlayer, and the radian of arcwall face is less than the radian of arc face.

Furthermore, the middle part of the buffer layer is provided with a radial extrusion hole, and the arc surface are respectively contacted with the outer plastic layer and the protective layer on two sides of the buffer layer.

Further, the thickness of the coating material layer is 0.6-1.2 mm.

Furthermore, the surface of the wear-resistant layer is provided with a plurality of protruding wear-resistant blocks.

Furthermore, the inner layer and the outer plastic layer both adopt synthetic fibers.

The utility model has the advantages that: according to the utility model, the bulges and the arc surfaces are arranged on the inner side and the outer side of the buffer layer, so that the extrusion force generated by folding can be relieved by the raised columns and the arc surfaces when the hoses are transported or stacked, the main body can prevent the hoses from being excessively extruded to generate extrusion elasticity, the friction between the buffer layer and the outer plastic layer can be reduced by the arc surfaces, and the bearing capacity of the hoses on the impact force of water can be increased by the arc surfaces.

Detailed Description

For the purpose of enhancing an understanding of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.

As shown in fig. 1, a water delivery plastic-coated hose, an inner layer 1 is sequentially provided with a coating material layer 2, a compression-resistant layer 3, an outer plastic layer 4, a buffer layer 5, a protective layer 6 and a wear-resistant layer 7, the coating material layer 2 is 0.6-1.2mm thick, the inner layer 1 and the outer plastic layer 4 are both made of synthetic fibers, the surface of the wear-resistant layer 7 is provided with a plurality of outstanding wear-resistant blocks to increase wear resistance, the compression-resistant layer 3 is connected with the coating material layer 2 and the outer plastic layer 4 through an occlusion wire harness 31, two sides of the buffer layer 5 are respectively provided with a bulge 51 and an arc surface 53, a gap 52 is arranged between the bulges 51, when the water delivery plastic-coated hose needs to be folded, the buffer layer 5 can play a certain role of relieving deformation, and can generate a certain pressure on the inner side wall of a pipe when the water pressure is rapidly increased during water delivery in the pipe to extrude the inner side wall, buffering is effectively mitigated.

Be equipped with protruding 51 on the buffer layer 5 side wall that is close to inlayer 1, be equipped with clearance 52 between the protruding 51, clearance 52 is outside concave surface 54, protruding 51 includes cylinder 511 and arc surface 512, arc surface 512 is located the top of cylinder 511, when the water delivery plastic-coated hose convolutes, cylinder 511 and the support of mutual extrusion between, prevent that the inside wall of water delivery plastic-coated hose from suffering the biggest extrusion, the setting of arc surface 512 can reduce and produce the friction between buffer layer 5 and the outer plastic layer 4.

The arcwall face 53 is located the buffer layer 5 in proper order and is kept away from one side of inlayer 1, and the radian of arcwall face 53 is less than the radian of arc surface 512, and the arcwall face 53 can be alleviated because the too big pressure that produces of water conservancy when preventing buffer layer 5 extrusion fracture.

The middle part of the buffer layer 5 is provided with a radial extrusion hole 55, the arc surface 512 and the arc surface 53 are respectively contacted with the outer plastic layers 4 and the protective layers 6 on two sides of the buffer layer 5, and the extrusion degree of the buffer layer 5 can be increased through the extrusion hole 55.
