Abstract

The utility model relates to a connector structure of a hose, comprising a hose, an inner hose and an outer connector, wherein the hose is hollow, with two communicated ends; the inner hose made of plastic or rubber are arranged at intervals in the hose, and the outer connector is flexibly sheathed on the hose. The connector structure for the hose is characterized in that an inner connector is formed through secondary injection molding in one piece with the ports of the hose and the inner hose; the structure is used, so that the number of elements for constituting the hose connector are few, the production cost is low, the connector is easy to install, and the connection is more stable.

Description

The connecting head structure of flexible pipe

Technical field

The utility model is meant a kind of flexible pipe that connects usefulness especially about a kind of link, with its connecting head structurally associated.

Background technique

As shown in Figure 1, 2, the metallic hose that connects water pipe and outlet terminal (as tap, gondola water faucet etc.) for a kind of common being used to, include metallic hose 1 ', the one inner flexible tube 2 ' gap of being made by plastics or rubber is arranged in the metallic hose 1 ', be combined with on the port of this metallic hose 1 ' and inner flexible tube 2 ': an inner sleeve 3 ', be arranged in the gap between metallic hose 1 ' and the inner flexible tube 2 ', the outer end of this inner sleeve 3 ' forms a flange 31 '; The lining 4 ' of one tool through hole, drive fit is arranged in the inner flexible tube 2 ', its outer end then radially extends to form a ring edge 41 ', one outer sleeve 5 ', be enclosed within on the metallic hose 1 ', with fit in inner sleeve 3 ' and the lining 4 ' metallic hose 1 ' and inner flexible tube 2 ' port section together firmly are combined together to form joint, be connected with water pipe or outlet terminal by a socket that is movably set on the metallic hose 1 ' again, as seen, the joint of above-mentioned metallic hose need by a plurality of constitute form, have the deficiency that member is many, assembling is cumbersome, fitment stability is relatively poor.

The model utility content

Therefore, the utility model is at the above-mentioned deficiency of commonly using hose coupling, provides a kind of and assembles easily, the connecting head structure of the flexible pipe of joint good stability.

The utility model is adopted following technological scheme to reach above-mentioned purpose:

A kind of connecting head structure of flexible pipe, comprise a flexible pipe, this flexible pipe is the hollow tube that two ends connect, the one inner flexible tube gap of being made by plastics or rubber is located in the described flexible pipe, one socket is loosening is enclosed within on this flexible pipe, and it is particularly in the one-body molded spigot of quadric injection mould on the port of this flexible pipe and inner flexible tube.

The exterior edge face of this spigot radially extends to form a flange, and this socket inwall is formed with step that should flange.

Adopt such scheme, because spigot is directly one-body molded at flexible pipe and inner flexible tube quadric injection mould on port, make that the member of forming hose joint is few, manufacture cost reduces, and it is easier that joint is installed, and connects more firm.

Description of drawings

Fig. 1 is for commonly using the hose joint structure;

Fig. 2 is for commonly using hose joint structure sectional view;

Fig. 3 is a STRUCTURE DECOMPOSITION schematic representation of the present utility model;

Fig. 4 is an assembled sectional view of the present utility model.

Embodiment

As Fig. 3, shown in 4, the connecting head structure of the utility model flexible pipe, comprise a flexible pipe 1, the hollow tube that this flexible pipe 1 connects for two ends, one inner flexible tube 2 gaps of being made by plastics or rubber are located in the aforementioned flexible pipe 1, the one-body molded spigot 3 of quadric injection mould on the port of this flexible pipe 1 and inner flexible tube 2 specifically, utilize this spigot 3 can make flexible pipe 1 on port, form firm combining with inner flexible tube 2, and the exterior edge face of this spigot 3 radially extends to form a flange 31, one socket, 4 loosening being enclosed within on the metallic hose 1, its inwall is formed with the step 41 of corresponding flange 31, when flexible pipe 1 was connected with external member by this socket 4, the step 41 of this socket 4 can be resisted against the flange 31 of spigot 3.

The utility model is because spigot 3 is directly one-body molded at flexible pipe 1 and inner flexible tube 2 quadric injection mould on port, and flexible pipe 1 and inner flexible tube 2 can be combined in the port simultaneously, make that the member of forming hose joint is few, manufacture cost reduces, and it is easier that joint is installed, and connects more firm.

Claims
