By providing the folding tube 603 bent between the fixed tube 602 and the water pumping port 5, the bending position of the folding tube 603 will not be easily deflated, thereby avoiding the occurrence of the deflation phenomenon of the traditional leather tube 601 being directly bent.

[0032] The end side of the rotating shaft 605 is fixedly connected with a fixing pin 606, and the side wall of the fixing pin 606 is evenly provided with a plurality of slots 607. The side wall of the connecting plate 608 is slidably connected with a sliding frame 611, and a block 612 is fixedly installed on the surface of the sliding frame 611, and the size of the block 612 is adapted to the size of the slot 607. The sliding frame 611 is inserted into the inner side of the slot 607 on the fixing pin 606, so as to realize the fixing work of the folding tube 603 after bending. A spring 613 is fixedly connected between the sliding frame 611 and the connecting plate 608. The sliding frame 611 is inserted into the inner side of the slot 607 on the fixing pin 606 by the elastic force of the spring 613. A positioning pin 609 is fixedly installed on the surface of the sliding frame 611, and the other end of the positioning pin 609 is rotatably connected with a support plate 610. The support plate 610 on the positioning pin 609 is rotated to support the support plate 610 on the surface of the connecting plate 608, so as to achieve temporary support work for the position of the sliding frame 611 and the block 612 after pulling.

[0033] Reference Figure 1-Figure 3 and Figure 5 As shown, specifically, the wrapping structure 7 includes a sponge cover 73 sleeved on the outside of the folded tube 603, and a plurality of insertion holes 74 are evenly opened on the end side of the sponge cover 73, and a rubber strip 72 is arranged on the inner side of the insertion hole 74. The sponge cover 73 is sleeved on the outside of the folded tube 603 to cover the position of the tube opening of the folded tube 603, thereby avoiding the phenomenon that noise is easily generated at the bend of the pipe due to the thin structure of the folded tube 603.

[0034] The end side of the rubber strip 72 is fixedly connected with a plug 76, and the plug 76 is a step structure.

The side wall of the rubber strip 72 is fixedly connected with a plurality of protrusions 75, and the outer side of the sponge cover 73 is glued with a plastic film 71. The protrusions 75 increase the friction force of the rubber strip 72 inserted into the inner side of the socket 74, thereby improving the stability of the rubber strip 72 inserted into the inner side of the socket 74.

[0035] Working principle: A device is made to effectively solve the problem of liquid reflux. The device consists of a water inlet 5, a water outlet 3, a pressure regulating tower column 4, and a water pump 2. The device is installed at the water inlet position of the water pump 2. When the pressure in the pipeline is lower than the water level in the pressure regulating tower column 4, the pressure regulating tower column 4 replenishes water to the pipeline to prevent the water column from breaking and avoid filling when the pump is started next time. When the water valve is closed or liquid reflux occurs in the water pump 2, the pressure in the pipeline is greater than the pressure in the water tower, and the refluxed liquid flows to the pressure regulating tower to fill it, and the refluxed liquid caused by the remaining excess pressure flows back to the pool, thereby effectively solving the problem of liquid reflux. By setting a folding tube 603 bent between the fixed tube 602 and the water inlet 5, the bending position of the folding tube 603 will not be easily deflated, thereby avoiding the occurrence of the deflation phenomenon caused by the direct bending of the traditional leather tube 601. When the direction of the leather tube 601 needs to be adjusted, First, pull the slide frame 611, rotate the support plate 610 on the positioning pin 609, and support the support plate 610 on the surface of the connecting plate 608, so as to achieve temporary support work for the slide frame 611 and the position of the block 612 after pulling. At this time, the two connecting plates 608 on the two rotating pins can be rotated, and after the folding tube 603 is bent to the required angle, the support plate 610 located on the connecting plate 608 is rotated out. At this time, the slide frame 611 will be inserted into the inner side of the card groove 607 on the fixing pin 606 by the elastic force of the spring 613, so as to achieve the fixing work of the folding tube 603 after bending, and then achieve the adjustment work of the pipe mouth direction of the fixed pipe 602. By setting the adjustment device 6, the flexible bending and adjustment work of the pipeline at the water pumping port 5 is facilitated, and the pipeline will not be deflated during the bending process, which improves the performance of the anti-backflow device to a certain extent.

[0036] The sponge sleeve 73 is put on the outside of the folded tube 603 to cover the tube mouth of the folded tube 603, thereby avoiding the phenomenon that noise is easily generated at the pipe bending position due to the thin structure of the folded tube 603, and improving the noise reduction effect at the pipe bending position. The side of the rubber strip 72 with the plug 76 is inserted into the inner side of the socket 74. The plug 76 with a stepped structure improves the docking efficiency with the socket 74. Selecting a suitable number of rubber strips 72 to insert into the inner side of the socket 74 facilitates the expansion of the sponge sleeve 73, thereby improving The tightness between the sponge cover 73 and the folding tube 603 is improved. By setting the protrusion 75, the friction of the rubber strip 72 inserted into the inner side of the hole 74 is increased, thereby improving the stability of the rubber strip 72 when used inside the hole 74. The plastic film 71 is set to a certain extent to improve the waterproof performance and corrosion resistance of the outer side of the sponge cover 73 during use, thereby extending the service life of the sponge cover 73. By setting the wrapping structure 7, the covering work of the folding tube 603 position is facilitated, and the use effect of the folding tube 603 position is further improved.
