[0008] Figure 1 This is a cross-sectional view of the connecting hose.

[0009] In the diagram, 1. Hose body; 2. Adapter; 3. Opening and closing frame; 4. Shaft; 5. Contact ring; 6. Limiting ring; 7. Return spring; 8. Opening and closing ring. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown, this connecting hose includes a hose body 1 with a connecting end. An adapter 2 is provided at the connecting end of the hose body 1 and can meet connection requirements in different directions. The adapter 2 consists of a straight pipe 1 and a straight pipe 2 perpendicularly connected to the straight pipe 1. The interiors of the straight pipe 1 and the straight pipe 2 are interconnected. Both the outer ends of the straight pipe 1 and the straight pipe 2 are provided with opening / closing units for controlling the opening and closing of the straight pipe 1 or the straight pipe 2 and preventing impurities from entering. The opening / closing unit includes an opening / closing frame 3, a shaft 4, a contact ring 5, a limiting ring 6, and a return spring 7. The opening / closing frame 3 is disposed inside and connected to the straight pipe 1 or the straight pipe 2. The opening / closing frame 3 has several through holes arranged along its circumference, and an assembly hole for the shaft 4 to pass through for installation. The limiting ring 6 is also located inside and connected to the straight pipe 1 or straight pipe 2. The limiting ring 6 is located on the outside of the corresponding opening and closing frame 3. The abutment ring 5 is sleeved on the shaft 4 and connected to it. The abutment ring 5 is located between the limiting ring 6 and the opening and closing frame 3. The return spring 7 is also sleeved on the shaft 4. The two ends of the return spring 7 abut against the abutment ring 5 and the opening and closing frame 3 respectively. An opening and closing ring 8 is provided on the outer end of the shaft 4, which is connected to it and cooperates with the convex ring and controls the opening and closing unit to be normally open. The inner diameter of the opening and closing ring 8 is larger than the outer diameter of the shaft 4. The opening and closing ring 8 is connected to the shaft 4 through several connecting rods. When other pipe fittings are connected to the adapter 2, the connecting pipe fittings will drive the opening and closing ring 8 to move accordingly, thereby separating the abutment ring 5 and the limiting ring 6, thus putting them in a connected state.
