[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a concrete pumping pipe quick connection device, comprising a pumping pipe 1, the connecting ends of the pumping pipe 1 are respectively threadedly connected with a connecting male head 2 and a connecting female head 3, the connecting male head 2 and the connecting female head 3 are collectively referred to as a connecting head, a flange 4 is fixedly installed on the outer surface of the connecting head, a semi-annular flange hole 5 is opened in the middle of the flange 4, and a sealing ring 6 is opened on the end surface of the connecting head, and an extruded and deformed sealing gasket 10 is arranged inside the sealing ring 6, a sliding column 12 is arranged inside the flange hole 5, and a notch 13 is opened at one end of the sliding column 12 at the connecting female head 3, and a protrusion 14 adapted to the notch 13 is fixedly installed on the surface of the connecting female head 3.

[0025] The male connector 2 is provided with raised rings 7 on both sides of the sealing ring 6, and the female connector 3 is provided with grooves 8 on both sides of the sealing ring 6. The raised rings 7 are sleeved inside the grooves 8. Such a setting can improve the sealing effect.

[0026] A positioning hole 9 is formed on the inner wall of the sealing ring 6 of the male connector 2, and a positioning rubber head 11 inserted into the positioning hole 9 is provided at one end of the sealing gasket 10. This arrangement can fix the position of the sealing ring 6, thereby preventing the sealing ring 6 from rotating.

[0027] The positioning rubber head 11 is glued to the connecting male head 2, and the two can be fixed by such an arrangement. At the same time, the positioning rubber head 11 can prevent the sealing gasket 10 from hardening and losing the sealing effect during the gluing process.

[0028] A plurality of sliding posts 12 are located on one side of the connecting male head 2 and are fixedly connected by a connecting ring 20. A handle 15 is provided on the outer side of the connecting ring 20. A positioning post 16 is slidably connected to the middle part of the handle 15. A flange 4 at the connecting male head 2 is provided with a latching tooth 17 for hindering the rotation of the positioning post 16. Through such a setting, a plurality of positioning posts 16 can be adjusted at the same time, thereby increasing the number of positioning posts 16 and achieving a better fixing effect.

[0030] Working principle: The male connector 2 and the female connector 3 are pre-connected to the pumping pipe 1. Such a setting can reduce production costs. The male connector 2 and the female connector 3 are aligned and squeezed to make the sealing ring 6 elastically deform. At this time, the rotating connecting ring 20 drives the positioning column 16 to rotate, so that the notch 13 is sleeved on the outer surface of the protrusion 14 to achieve positioning. In order to prevent the positioning column 16 from resetting and rotating, the positioning column 16 is set and the sliding positioning column 16 is engaged with the latch tooth 17, so that the effect of quickly connecting the pumping pipe 1 can be achieved.
