Description
Technical Field
The utility model relates to a structure of tube head, in particular to novel tube head structure.
Background
The quality of the tube head construction of a hose, in particular a breathing hose, is one of the keys in determining the quality of the hose. When the thread ends of the existing breathing hose are fixed, the joint part of the breathing hose is basically formed by secondary encapsulation injection molding, namely, the thread ends of the connecting threads and the tube head of the hose are firstly put together, and then the thread ends and the tube head are fixedly coated by the joint part of the hose in a direct injection molding mode to form the hose joint. However, in the conventional tube head structure, the hose joint formed by secondary encapsulation is only used for fixedly connecting the end of the connecting line and the end of the hose, so that in the using process, the line head of the connecting line is loosened and falls off due to bending, dragging and folding and the like, the line contact is poor, and the use of the hose is affected. Therefore, there are many unreasonable points for the conventional tube head structure, and improvement is needed.
SUMMERY OF THE UTILITY MODEL
To the above, the utility model aims to provide a novel tube head structure, to the line head of connecting wire fix in advance, follow-up rubber coating, fix in advance promptly and arrange the solid in the same direction as the back of knot and carry out secondary rubber coating injection moulding again and form flexible glue hose joint, guarantee the fixed effect at connecting line head of a thread position, avoid appearing the pine phenomenon of taking off, improve the whole quality of hose.
The utility model adopts the technical proposal that: the utility model provides a novel tube head structure, includes hose, connecting wire and hose nipple, the nose portion of hose is provided with the ebonite retainer plate in advance, the joint portion of connecting wire is provided with the ebonite mounting in advance, the ebonite retainer plate passes through the joint structure with the ebonite mounting and connects in advance fixedly, hose nipple passes through flexible glue secondary rubber coating injection moulding to the nose portion of the hose after the joint links together with the joint portion cladding of connecting wire.
The utility model has the advantages of it is following: through having set up the ebonite retainer plate in advance at the nose portion of hose and having set up the ebonite mounting in advance at the connector portion of connecting wire, the ebonite retainer plate is fixed with the ebonite mounting joint in advance after, and the flexible coupling is gone out to rethread flexible glue secondary rubber coating injection moulding, and consequently, the end of a thread position (solid in the same direction) of connecting wire just is difficult to become flexible on the tube head and drops.
The present invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
