Description

Bending protect and pressureproof garden hose

The present invention relates to a high pressure resistant garden hose, and more specifically, to a hose for supplying water, a high pressure resistant garden hose which can prevent breakage of the hose due to twisting or folding of the hose or pressure of a fluid. It is about.

In general, the hose is applied to various fields as a means for transporting fluid, and is made of a material suitable for the purpose of the hose and the nature of the fluid.

The present invention relates to a garden hose (garden hose for supplying water to garden water at home), the hose generally used for this purpose is made of a single tubular form, the material of which is a flexible synthetic resin flexible Conventional soft synthetic resin garden hose is mainly composed of a single tube made of a single body, so it may be easily bent or folded during use, and the flow of the fluid may not be smooth, as well as the internal pressure when the flow of the fluid is blocked by folding. As a result, not only the part of the hose bursts or the connection part of the hose is easily separated, but also consists of a soft synthetic resin unit, which is easily damaged from a sharp or sharp object, which causes water leakage during the fluid supply. Residual inside the hose Or that break easily by freezing the fluid has the disadvantage that such freezing.

The present invention is to solve the problems of the conventional soft plastic garden hose as described above, it is flexible and easily bent or folded to form a multi-layer, so that even if a portion of the surface is damaged leakage does not occur knitting yarns High tensile force in the constituent seals reduces the length of the hose, strengthens the bearing capacity by the yarn of the braided layer, and withstands the fluid pressure from the inside of the tube, and also insulates by the air layer of the hollow part formed in the spirally wound reinforcement. It is possible to prevent freezing by the effect, so it can be easily used in winter, and the reinforcement does not appear directly to the outside to provide a refractory pressure garden hose made of a new type of soft synthetic resin with a beautiful appearance.

Moreover, after covering a heavy pipe on the knitting layer wound by the inner pipe, a reinforcement can also be wound up and manufactured.

The present invention has a feature that consists of a braided layer formed on the outer circumferential surface of the inner tube in a cross shape or a straight shape, a hard reinforcement having a hollow portion formed therein spirally wound on the braided layer, and an appearance in which the reinforcement is buried. In the present invention, the reinforcement has a hollow portion formed inside and a thin coating layer is formed on the outer surface with the same material as the inner tube and the outer surface, and when wound on the knitting layer, it is wound with one strand or with two strands. After coating the inner tube on the knitting layer wound on the inner tube, the reinforcing body may be wound in a spiral shape. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the hose according to the present invention and the knitting layer (3) is formed on the outer circumferential surface of the inner tube (2) made of soft vinyl chloride resin cross each other or formed in a straight shape and And a rigid reinforcement 4 made of polyfuropropylene resin spirally wound on the knitting layer 3, and an exterior 5 made of soft vinyl chloride resin coated so that the reinforcement 4 is embedded. .

The hard reinforcement 4 has a hollow portion 6 formed therein and a thin coating layer 8 formed of the same material as the soft inner tube 2 and the outer surface 5 on the outer surface thereof, and the knitting layer 3 ) When wound on, it indicates that one strand or two strands are wound simultaneously.

4 and 5 show another embodiment of the hose according to the present invention, after the yarns intersect each other on the outer circumferential surface of the soft inner tube (2) or to form the braided layer (3) in a straight line, the outer surface After covering the soft tube (7) in the spiral, the spiral reinforcing body (4) having a hollow portion (6) formed on the outer circumferential surface of the tube (7) spirally wound and coated with a soft appearance (5) thereon Refractory pressure garden hose.

At this time, the reinforcement (4) is formed on the outer surface as shown in Figure 3 mentioned above, the thinner soft coating layer (8) of the same material as the soft inner tube (2) and the outer appearance (5) is wound on the knitting layer (3) The yarns which are wound with 1 strand of Gimsi or 2 strands at the same time and which make up the knitting layer 3 are polyester yarns. The reinforcement 4 is a hard synthetic resin, which is a polypropylene resin, an inner tube (2) and an appearance. (5) is a soft vinyl chloride resin, the inner and outer appearances (2) and (5) and the reinforcement (4) is not affixed to each other because they do not adhere to the outer layer of the reinforcement (4) using a soft vinyl chloride resin coating layer Forming 8 makes the bond between the reinforcing body 4 and the inner tube 2 and the exterior 5 to be firm. FIG. 6 shows yet another embodiment of the hose according to the present invention. To form a larger and more tightly wrapped so that the heat insulation effect is large due to the air in the hollow part (6) In addition, the reinforcement body 4 also tightly wraps the inner tube 2, and the coating layer 8 on the outer surface of the reinforcement body 4 also forms a thick layer, thereby greatly increasing the flexibility of the hose as a whole.

The construction process of the present invention is as follows. In the present invention, the knitting layer 3 is not constituted by weaving the warp and the warp yarns, but the yarns are naturally placed on the outer circumferential surface of the inner tube 2. In the hose manufacturing process, the thread is inserted in the direction in which the hose is extruded so that the threads are arranged in one direction. In order to configure the threads to cross each other, the thread is inserted while rotating the thread inserted into the extruder.

As shown in FIGS. 1 to 3, a yarn 6 is formed on the outer circumferential surface of the soft inner tube 2 so that the yarns form a straight line or cross each other, and then a hollow part 6 is formed therein. The spirally wound hard reinforcement (4) having a coating layer (8) formed on the outer periphery can be wound simultaneously, and one or two strands can be wound simultaneously. At this time, the outer surface of the reinforcement (4) is the inner tube (2) and the appearance Since the coating layer (8) made of soft vinyl chloride resin of the same material as (5) is formed, the hard reinforcement (4) having the soft coating layer (8) formed on the outer periphery is easily fused with the soft appearance (5). At this time, the refraction pressure hose of the present invention is completed. At this time, the reinforcement body 4 made of hard polypropylene resin is positioned in the coating layer 8 made of soft vinyl chloride resin and flows in the longitudinal direction and moves slightly. The hose of the present invention has a rigid reinforcement (4) inside the soft appearance (5) Because it is located and buried, the curved surface of the soft exterior 5, which appears to the outside by the hard reinforcement 4, can be kept soft, and contaminants adhere to the outer surface of the hose due to the curved surface of the reinforcement 4 It can reduce the appearance and keep the appearance foolish.

When the fluid is transferred using the refractive index pressure hose of the present invention, the hose is not easily bent or twisted by the braided layer 3 and the hard reinforcement 4 during use, so that the fluid flows smoothly, and the external It is possible to prevent the breakage easily even when contacted with a sharp or sharp material of the body, i.e., when the impact is applied from the outside of the hose, the reinforcement made of hard polypropylene resin, which is located inside the exterior (5) and spirally wound ( 4) flows between the outer tube 5 and the inner tube 2 made of soft vinyl chloride resin to absorb shocks and elastically elastic, so that it can be easily restored to its original form. The reinforcement body 4, which is a hard material inside the exterior 5, flows in the longitudinal direction slightly in the coating layer 8, which is a soft material, and breaks or breaks the hose while responding to an external force. Support and thereby maintain the circular hose intact.

Inside the rigid reinforcement 4, the hollow part 6, which is an air layer, is formed and the multi-layered hoses are integrally fused to provide robustness and flexibility at the same time and to suppress freezing phenomenon due to freezing during the winter. In the winding of the rigid reinforcement (4) formed on the soft coating layer (8) outside the knitting layer (3) or the soft tube (7) outside, and wound at the same time by supplying two strands, one strand is supplied It can shorten working time than winding and increase productivity.

The coating layer 8 of the reinforcement 4 is formed on the outer surface of the reinforcement 4 made of hard polypropylene resin by forming a coating layer 8 made of the same soft vinyl chloride resin as the exterior 5 and the inner tube 2. ) Is firmly fused integrally with the inner tube (2) and the outer tube (5) to form a single-layered hose in a single body to maintain flexibility and rigidity. That is, the reinforcement (4) is a rigid polyfuropropylene The inner tube (2) and the outer tube (5) are made of a soft vinyl chloride resin. The coating layer 8 is formed of a soft vinyl chloride resin on the circumferential surface to make the adhesion between the reinforcing body 4 and the inner and outer shells 2 and 5 more robust. As another embodiment of the hose according to the present invention, after forming the cross-shaped or straight-shaped knitting layer 3 on the outer circumferential surface of the soft inner tube 2, The outer surface is coated with a heavy pipe (7) made of soft synthetic resin, and then spirally wound the hard reinforcement (4) having a hollow portion (6) formed therein on the outer circumferential surface of the soft heavy pipe (7). (5) is a coating of the pressure resistant hose was completed, wherein the rigid reinforcement (4) formed with a soft coating layer (8) is wound in one strand or two strands at the same time as shown in FIG. It is wound.

After coating the soft core tube 7 on the knitting layer 3 wound on the soft inner tube 2, the hard reinforcement 4 on which the soft coating layer 8 is formed is wound in a spiral shape. Since the rigid reinforcement 4 having the hollow part 6 formed thereon is wound while being partially embedded in the soft heavy pipe 7, the rigid reinforcement 4 can be reliably and firmly fused. The hard reinforcement 4 in which the 8 was formed is more densely wrapped around the outer side of the knitting layer 3 and the soft pipe 7 on the inner tube 2, and the coating layer 8 on the outer peripheral surface of the reinforcement 4 is formed. The thickening of the layer can also increase the flexibility of the hose even more, i.e., the hollow part 6 is formed inside the reinforcement 4, so that the winter insulation effect and the hose can be bent or loaded When the reinforcement 4 is not cracked or cut, the resilience of the hose is excellent and the hose of the hose It increases the flexibility of the sieve 4 to further increase the flexibility of the hose. Further, by coating the outer peripheral surface of the reinforcement 4 with a synthetic resin of the same material as the soft appearance 5, the coating layer during bending of the hose 8 ) And the reinforcing body 4 maintain a predetermined shape and position, thereby preventing the gap between the reinforcing bodies 4 from being uneven, thereby preventing the flow of water in the folded portion without blocking the pressure resistance. The shape of the coating layer 8 corresponding to the curvature is deformed, but the reinforcement 4 is surrounded by the coating layer 8 to maintain a predetermined outer shape, thereby sufficiently having flexibility of the hose. In addition, since the reinforcement 4 is not attached to the coating layer 8, the selection of the required material corresponding to the required strength is possible, and thus the selection range of the reinforcement 4 is further widened. 3) By covering the heavy pipe (7) on the top, the knitting yarn is fixed on the knitting layer (3) so that the knitting structure is perfectly maintained, so that the entire hose can maintain a uniform pressure and the hose bends small, and it is also pressurized. It is possible to prevent the twisting of the hose by reducing the hose length change rate and minimizing the influence on the braided layer 3.

Refractory pressure garden hose according to the present invention is composed of a soft synthetic resin, it is not easy to bend or folded due to increased flexibility to prevent the flow blockage and breakage of the fluid due to bending or folding, to form a multi-layer surface part Even if it is damaged, it can not only prevent water leakage, but also keep the curved surface by the reinforcement body smoothly, and the appearance is also beautiful, and the freezing of the water remaining in the winter due to the heat insulation action by the air layer of the hollow part formed in the reinforcement body There is an effect that can be suppressed.
