Abstract

The utility model provides an articulated hose whose direction can be arbitrarily changed, which is composed of the connection in series of inner movable joints whose interiors are communicated and outer movable joints whose interiors are communicated; the contiguous inner and outer movable joints are connected through that one end of the outer movable joint can sheathed with one end of the inner movable joint whose outer diameter is matched with the end of the outer movable joint. Because of the connection adopting ball type, the direction can be flexibly changed, and the tight ness is good. The utility model has simple structure and convenient assembly and disassembly and can be used for transporting liquid and gas.

Description

A kind of Articulated hose

The utility model relates to a kind of Articulated hose of break-in arbitrarily.

Common transfusion or gas pipeline, or adopt rigid pipe, as steel pipe, iron pipe, glass tube etc., or adopt flexible pipe, as rubber tube or plastic flexible pipe etc.These rigid pipes or flexible pipe can satisfy the needs of most of occasion.But, in some occasion, both required pipe that certain rigid is arranged, can change direction again.At this moment, general method is that rigid pipe is disconnected, and connects by elbow to change direction, as running water pipe.This method is pretty troublesome, particularly frequently changes the place of direction for needs.

The purpose of this utility model provides a kind of Articulated hose, makes its existing certain rigid, can change direction arbitrarily again.

The purpose of this utility model is achieved in that Articulated hose adopts interior logical interior movable joint and alternate being in series of outer movable joint of Nei Tong, the outer surface at interior movable joint two ends is hemisphere, the internal chamber wall at outer movable joint two ends is hemisphere, between adjacent interior movable joint and the outer movable joint is to catch external diameter interior movable joint one end with matching by the inner chamber cover of outer movable joint one end to connect.Interior movable joint and outer movable joint all are interior logical, so Articulated hose can be infused or gas transmission etc.Adopt spherical the connection between interior movable joint and the outer movable joint, in conjunction with tightly, both torsional direction arbitrarily had certain rigid again.

The utlity model has simple in structure, break-in flexibly, the characteristics of convenient disassembly, the employing plastics are raw material, cost is low, and is corrosion-resistant, applied range is applicable to occasions such as transfusion, gas transmissions.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the half sectional view of Articulated hose.

Fig. 2 is the sectional view of interior movable joint.

Fig. 3 is the sectional view of outer movable joint.

As shown in Figure 1, Articulated hose is in series as shown in Figure 2 by interior movable joint (1) is alternate with outer movable joint (2), and logical in the interior movable joint (1), the outer surface at two ends is hemisphere, and intermediate portion is connecting tube (3).As shown in Figure 3, logical in the outer movable joint (2), the internal control wall at two ends is hemisphere, and intermediate portion also is connecting tube (3).When practical application, connecting tube (3) can make as required in different length and the shape movable joint (1) and outer movable joint (2) both can be when production disposable being in series, also can be connected in series as required in use and form.

Claims

1. Articulated hose, it is characterized in that this Articulated hose is by interior logical interior movable joint (1) and interior logical alternate being in series of outer movable joint (2), the outer surface at interior movable joint (1) two ends is hemisphere, the internal chamber wall at outer movable joint (2) two ends is hemisphere, between adjacent interior movable joint (1) and the outer movable joint (2) is to catch interior movable joint (1) one end that external diameter cooperates with it by the inner chamber cover of outer movable joint (2) one ends to connect

2. Articulated hose according to claim 1, the intermediate portion that it is characterized in that interior movable joint (1) and outer movable joint (2) is connecting tube (3).
