[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0021] The embodiments of the present utility model will be described below according to its overall structure.

[0022] Please refer to Figures 1-4 , this jet pump pipeline connection device includes a connecting pipe 1. One end of the connecting pipe 1 is provided with a threaded interface 2. The inner wall of the front end of the connecting pipe 1 is threaded, and the opening diameters at both the front and rear ends of the connecting pipe 1 are the same. The design of the inner wall of the connecting pipe 1 in the device as a threaded interface can make the connection more convenient and fast during use. A fixing knob 3 is sleeved outside the connecting pipe 1. Threaded rods 4 are installed at both the upper and lower ends of the fixing knob 3. The fixing knob 3 is threadedly connected to the connecting pipe 1 and is also threadedly connected to the threaded rods 4. The installed fixing knob 3 in the device can well fix the position where the connecting pipe 1 is connected to the jet pump. After fixing, by turning the threaded rod 4, the pipeline at the connection position can be reinforced after turning to prevent detachment. One end of the connecting pipe 1 is installed with a first protective frame 5. One end of the first protective frame 5 is installed with a second protective frame 6.
