Abstract
The utility model discloses a long sharp-nose single-thread poly ethylene (PE) flexible pipe. The long sharp-nose single-thread PE flexible pipe comprises a pipe body composed of a pipe main body, a pipe tail and a pipe head provided with an outer thread, and is characterized by further comprising a sharp-nose injection head which is molded with the pipe body in a split mode and is formed through independent injection molding, wherein a connection portion of the sharp-nose injection head is provided with an inner thread and is connected with the pipe head through the threads, a pipe cover matched with the sharp-nose injection head for use is further arranged at the outer surface of the sharp-nose injection head, a protruding portion is arranged at the periphery of the middle portion of the sharp-nose injection head, a groove corresponding to the protruding portion is arranged in the inner wall of the piper cover, and the sharp-nose injection head is connected with the pipe cover through a clamping groove. By means of the technical scheme, the sharp-nose injection head formed in an injection molding mode is large in hardness and good in quality, the sharp-nose injection head is matched with the pipe cover through the clamping groove at the same time, and secondary pollution due to the fact that pasty fluid contaminates the position of the threads and is difficult to clean in the squeezing out process is avoided.
Description
Technical field
The utility model relates to a kind of flexible pipe, particularly the sharp mouth single screw thread of a kind of length PE flexible pipe.
Background technology
Plastic composite hose is easy to use because of it, economy, wholesomeness are good, has become one of main packing kind of cosmetics, medicine and food.From eighties of last century nineties, China has introduced a large amount of advanced persons' composite soft tube production facilities from American-European, Japan and Taiwan Province, and growth momentum is very violent.Point out according to correlation report, the strong growth of skin-protection product and shower product will promote hose packing to exceed average speed increment, particularly upright flexible pipe.
Flexible pipe has advantages of that other materials hardly matches, and therefore, from appearance, just shows up prominently at cosmetics and medicine packing.More become at present cosmetics and the indispensable packaged form of medicine.Plastic composite hose is mainly used in the packing of the products such as cleansing cream, Cleansing Foam (milk), shower cream, shampoo, hair cream, hair conditioner, hair dye, depilatory cream, toothpaste at cosmetic industry.Cosmetics are customers of the maximum of flexible pipe at present, account for greatly 60%~70% of all business proportion of flexible pipe.Flexible pipe is mainly used in the packing of frost, paste class topical drug in pharmaceuticals industry, medicine occupies 15%~20% ratio in hose packing.
In the prior art at Chang Jianzui in the flexible pipe injection mo(u)lding, at the aperture aesthetic property at the gradient of taking into account hose body welding integraty, long sharp mouth head and evenness of wall thickness, head top, technology difficulty is very large; The head of traditional flexible pipe and pipe lid all are to adopt the folding lid mode that is threaded into, and lotion is infected with the difficult cleaning in screw thread place and the secondary pollution that causes in extrusion.
The utility model content
Technical problem to be solved in the utility model is a kind of quality that has guaranteed sharp mouth head and aesthetic property to be provided and can to avoid pipe to cover the sharp mouth single screw thread of the length that is subject to secondary pollution in the process of paste extrusion PE flexible pipe for shortcomings and deficiencies of the prior art.
The technical matters that the utility model solves can realize by the following technical solutions:
Long sharp mouth single screw thread PE flexible pipe, comprise by pipe shaft, the body of managing tail and forming with externally threaded tube head, it is characterized in that, comprise that also one divides body formed with described body and by independent injection molded sharp mouth head, the connecting portion of described sharp mouth head is provided with negative thread and is threaded connection with described tube head.
Especially, also be provided with a pipe lid that is used in conjunction with described sharp mouth head at the outside face of described sharp mouth head.
Especially, the middle part of described sharp mouth head circumferentially is provided with a salient, and the inwall of described pipe lid is provided with a groove corresponding with described salient, and described sharp mouth head is connected by draw-in groove with described pipe lid.
Owing to having adopted above-mentioned technical scheme, the sharp mouth head hardness of the utility model injection mo(u)lding is large, and quality is good, and sharp mouth head cooperates by the draw-in groove form with the pipe lid simultaneously, avoids lotion to be infected with in extrusion that screw thread place difficulty is cleared up and the secondary pollution that causes.
Description of drawings
Fig. 1 is the structural representation of the long sharp mouth single screw thread PE flexible pipe of the utility model.
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to illustrated in figures 1 and 2, long sharp mouth single screw thread PE flexible pipe comprises by pipe shaft 102, pipe tail 101 and the body 100 and the sharp mouth head 200 that form with the tube head 103 of outside thread 104.
The middle part outside face of point mouth head 200 circumferentially is provided with salient 202, pipe covers 300 inwall and is provided with groove 301 with salient 202 cooperatings, point mouth head 200 covers 300 and is connected draw-in groove with groove by salient 202 and is connected with managing, abandoned traditional connection mode that is threaded into, finish plug in the simplest mode, avoid simultaneously lotion in extrusion, to be infected with the difficult cleaning in screw thread place and the secondary pollution that causes.
The sharp mouth single screw thread of this length PE flexible pipe adopts the PE material to make, and has the characteristics such as anti-wear good, nontoxic, uvioresistant, elasticity are good, long service life, withstanding corrosion, is fit to load various lotion cosmetics, meets the need of market.
The sharp mouth head 200 of the sharp mouth single screw thread of this length PE flexible pipe uses the form of independent injection moulding to finish, guaranteed the total quality aesthetic property of sharp mouth bullet, because the forming temperature technique of hose injection head machine and injection machine is different, thereby so that the product feel hardness ratio hose injection head of injection machine moulding is confidential strong a lot; The applicable D19 of negative thread 203 specifications of point mouth head 200 22 the flexible pipe of 25 3 kinds of calibers use, thus should point mouth head 200 can satisfy simultaneously client D19 22 the supporting demand of 25 3 kinds of calibers.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
