Abstract

The utility model relates to a universal connecting hose with joints and without a hoop. The universal connecting hose comprises an inner layer of flexible pipe and an outer layer of hard pipe which are laminated, wherein the outer layer of hard pipe comprises cylindrical joints at two ends and a spiral strip connected between the cylindrical joints at the two ends; the spiral strip and the cylindrical joints at the two ends are in integrated connection; and the inner layer of flexible pipe is attached to the inner surface of the spiral strip and the cylindrical joints at the two ends in a hot melting mode. The spiral strip and the cylindrical joints at the two ends are in integrated connection, and the flexible inner pipe, the cylindrical joints at the two ends and the spiral strip are connected into a whole. The universal connecting hose is not fastened by the hoop during connection, so that the number of parts is effectively reduced, the construction time is reduced, the speed of the operation procedure is increased and the cost performance is totally improved. The flexible inner pipe is attached to the inner walls of the cylindrical joints at the two ends, so that the sealing property of the connecting joints is improved, the adhesive is not required during connection, the adhering parts are reduced, the construction is simplified and the universal connecting hose is convenient to disassemble and maintain.

Description

Can not have cuff from the universal connection flexible pipe of belt lacing

Technical field

The utility model relates to waterway pipe connecting element art, refer in particular to a kind of simple in structure, easy to use and do not had cuff that cost is lower from the universal connection flexible pipe of belt lacing.

Background technique

In waterway pipe connects, between water pipe and various watering equipments (for example Dish washing machine, water for bathing draining, water heater, medical equipment, air-conditioning), use always to the flexible pipe that is connected that can realize turning to.At present, the connection hose construction a kind of commonly used that occurs on the market is: include the rubber hose and the outer field protective tube of internal layer, there is connecting head at two, its protective tube has the spiral plate-like, and metal mesh shaped is also arranged, can be crooked.Yet; The existing connection flexible pipe of this kind is but found still to have many deficiencies on himself structure and the usability when reality is used; Fail to reach best using effect and task performance, especially be between its two ends connecting head, the outer protection tube, the internal layer flexible pipe to cause product component more by the split connecting structure on the one hand; Brought taking a lot of work in the production and assembly, time-consuming, and the management and the cost of transportation that increase each component; On the other hand, join strength is limited between each parts of split winding, and working life is short, after use a period of time, many hidden danger such as joint is deviate from, sealing weakens can occur.

The model utility content

The main purpose of the utility model provide a kind of simple in structure, easy to use and do not had cuff that cost is lower from the universal connection flexible pipe of belt lacing.

For realizing above-mentioned purpose, the utility model adopts following technological scheme:

A kind of universal connection flexible pipe that does not have cuff from belt lacing; Comprise internal layer flexible pipe and outer stereoplasm tube that lamination is compound; This skin stereoplasm tube comprises two ends tubular joint and is connected in the spiral bar between this two ends tubular joint; Being formed in one between this spiral bar and the two ends tubular joint is connected, and this internal layer flexible pipe hot melt is attached to the internal surface of this spiral bar and two tubular joints.

Preferably, said internal layer flexible pipe material is PE or PVC plastic cement flexible tube.

Preferably, said outer stereoplasm tube material is PE, PP or PVC hard plastic pipe.

The utility model compared with prior art has tangible advantage and beneficial effect, specifically comprises following several aspect:

(1) be formed in one between its spiral bar and the two ends tubular joint and be connected, flexible in pipe link into an integrated entity with two end connectors, spiral bar hot melt, product connects no cuff; Effectively reduce the part number; Thereby reduce the man-hour of constructing, improved the speed of flow chart, improved cost performance generally;

(2) tubular inner nosepiece wall in two ends is attached with flexible interior pipe, has improved the sealability of jointing, makes when connecting and can not use binder bonding, has reduced bonding position, has simplified construction, is convenient to dismounting, maintenance;

(3) the curved part employing is spiral-shaped, does not have kinking, can realize omnipotent the turning to that waterway pipe connects;

(4) resistance to compression, the property reversed, under pressurized, the situation turned round, pipe is unobstructed in can keeping.

Embodiment

Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:

Please referring to figs. 1 through shown in Figure 4; It has demonstrated the concrete structure of the preferred embodiment of the utility model; This connection flexible pipe comprises compound internal layer flexible pipe of lamination 10 and outer stereoplasm tube 20; This internal layer flexible pipe 10 can be PE, PVC plastic cement around the property pipe, this skin stereoplasm tube 20 can be plastic cement pipes such as hard PVC, PP, PE, this skin stereoplasm tube 20 comprises two ends tubular joint 21 and is connected in the spiral bar 22 between this two ends tubular joint 21; Being formed in one between this spiral bar 22 and the two ends tubular joint 21 is connected, and these internal layer flexible pipe 10 hot melts are attached to the internal surface of spiral bar 22 and two tubular joints 21.

During use; Utilize the tubular joint 21 connecting object winding fit corresponding at two ends with its two; In the winding process; The internal layer flexible pipe 10 that is attached to tubular joint 21 inwalls forms anti-being tightly connected of leaking, and forms the curved part of the connection flexible pipe of present embodiment, realization universal adapting by these spiral bar 22 parts.

In sum; The design focal point of the utility model is, it is connected being formed in one between spiral bar and the two ends tubular joint, flexible in pipe link into an integrated entity with two end connectors, spiral bar hot melt; Effectively reduce the part number; Thereby reduce the man-hour of constructing, improved the speed of flow chart, improved cost performance generally; Two ends tubular inner nosepiece wall is attached with flexible interior pipe, has improved the sealability of jointing, makes when connecting and can not use binder bonding, has reduced bonding position, has simplified construction, is convenient to dismounting, maintenance; Curved part adopts spiral-shaped, does not have kinking, can realize omnipotent the turning to that waterway pipe connects; And, the utlity model has preferable crushing resistance and the property reversed, under pressurized, the situation turned round, pipe is unobstructed in can keeping.

The above embodiment has only expressed the part mode of execution of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model protection domain.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with accompanying claims.
