Abstract

The utility model relates to a soft pipe for a fluid pipeline, which is composed of the coupling in series of movable joints whose interiors are communicated; the sizes and the shapes of the movable joints are same the movable joints are mutually in movable sheath coupling through the hemispherical joint heads and joint head sleeves matched with the connectors of both ends of the movable joints; the utility model is provided with a sealing ring. Because the structure of rotary coupling of spherosome is adopted between the joint head and the joint sleeve, the utility model has the advantages of simple structure, flexible fold, good sealability, convenient disassembly, lower cost, etc. The utility model can be used for occasions that pipelines for transferring gas and liquid has the requirements of turn, bend and fold and seal in machine tool industry, electric appliance industry, chemical industry, post and telecommunication industry, water heating industry, buildings industry, etc.

Description

Universal ball type soft pipe

The utility model relates to a kind of soft folding pipe of fluid circuit, and particularly fluid hose one end position is fixed, the other end is optionally rotated, the Articulated hose of bending.

The flexible pipe that uses in the now industrial or daily life can be summed up as two classes, one class is the soft folding pipe that utilizes metallic material to make, another kind of is the annular corrugated flexible pipe that utilizes plastics to make, the former, the manufacture cost height, corrosion easily, sealing is poor, and length can not be regulated arbitrarily, the latter, owing to have rebound phenomenon to exist, so can not freely turn to, stand upright arbitrarily.

The purpose of this utility model is to provide a kind of and turns back flexibly, good airproof performance, corrosion resistant universal ball Articulated hose.

The universal ball Articulated hose is formed by the interior logical movable joint string knot big or small, that shape is identical.Movable joint one end is for being hemispheric joint, and the hemisphere joints sleeve that the other end matches with joint for its internal diameter connects by joint and joints sleeve kink between the movable joint.Because the structure that has adopted garden spheroid rotation to connect between hemisphere joint and the joints sleeve, so Articulated hose can turn to curved moving arbitrarily.

The utility model will be further described below in conjunction with embodiment shown in the drawings.

Fig. 1 is the utility model structural representation, and Fig. 2 is Figure 1A-A cutaway view Amplified image, and Fig. 3 is that the utility model connects schematic representation with nozzle, and Fig. 4 is that the utility model is chewed with valve and connected schematic representation.Among the figure: 1, seal ring; 2, joint; 3, joints sleeve; 4, movable joint; 5, nozzle; 6, valve is chewed.

The utility model is formed by the interior logical movable joint big or small, that shape is identical 4 string knots.Interior logical movable joint 4 one ends are for being hemispheric joint 2, and the vertical place with central shaft of joint 2 outer surfaces has annular groove, and groove is built-in with the seal ring 1 that matches with it, and the other end is the half garden T-joint cover 3 that internal diameter matches with joint 2.When movable joint 4 connects, the joint 2 of movable joint 4 is inserted in the joints sleeve 3 of another movable joints 4, serial connection is successively determined serial connection length more according to actual needs then; It can be connected into the whole pipeline of multi-form, specification and length by load.

The universal ball Articulated hose can also be with nozzle 5, valve is chewed various outlets such as 6 or the import pipe fitting is combined into the various uses form, an end of only requiring pipe fitting is made with the Articulated hose end and is got final product to joints sleeve 3 or the joint 2 that movable joint 4 joints 2 or joints sleeve 3 match, and sees Fig. 3, Fig. 4.

Obviously, the utlity model has to tear open and drive convenient, good airproof performance, simple in structure, turn back flexibly advantage such as at the bottom of the cost.Can be widely used in industries such as lathe, electrical equipment, chemical industry, post and telecommunications, hot-water heating, building have turn to, curved scratch, occasions such as the gas transmission of seal request, liquid-transport pipe-line connection.

Embodiment of the present utility model adopts the ABS engineering plastics, logical movable joint 4 joints 2 external diameter 15mm in it, joints sleeve 3 external diameter 20mm, length 23mm.

Claims

1, a kind of universal ball Articulated hose, it is characterized in that: it is formed by interior logical movable joint (4) the string knot big or small, that shape is identical, movable joint (4) one ends are for being hemisphere joint (2), the joints sleeve (3) that the other end matches with joint (2) for its internal diameter connects by joint (2) and joints sleeve (3) between the movable joint (4).

2, universal ball Articulated hose according to claim 1 is equipped with seal ring (1) between it is characterized in that joint (2) and joints sleeve (3) connecting.
