[0028] The following further elaborates on this application through the drawings and embodiments.

[0029] Refer to Figures 1 to 4, an embodiment of the present application provides a socket flexible joint steel pipe connection joint for water supply, including a steel pipe 1. Fixed components 2 are provided at the end faces of both steel pipes 1. A connection component 3 is arranged between the two fixed components 2. The fixed component 2 includes a rubber sleeve 21. The steel pipe 1 is inserted into the inside of the rubber sleeve 21. A groove 22 is formed on the outer side wall of the rubber sleeve 21. A snap ring 23 is clamped inside the groove 22. A bolt 24 is fixedly installed between the upper and lower snap rings 23.

[0030] The part of the steel pipe 1 located inside the rubber sleeve 21 is completely attached to the inside of the rubber sleeve 21. The rubber sleeve 21 is a corrosion-resistant and waterproof rubber.

[0031] In this embodiment, when the steel pipe 1 is connected to the rubber sleeve 21, first, the rubber sleeve 21 is sleeved on the outer side of the corresponding steel pipe 1. After sleeving, the snap ring 23 is clamped between the grooves 22. After clamping, the bolt 24 is installed between the upper and lower snap rings 23 to fix the snap ring 23. After the snap ring 23 is fixed, the lower rubber sleeve 21 is extruded by the extrusion force of the snap ring 23, and the extrusion position is inside the groove 22. The rubber layer at the groove 22 is thinner and can be deformed better and attached to the outer side of the steel pipe 1 after being extruded, so that the connection between the steel pipe 1 and the rubber sleeve 21 can be sealed better, greatly reducing the probability of leakage.

[0032] Refer to Figures 1 to 4 , in one aspect of this embodiment, the connection component 3 includes a first metal ring 31 and a second metal ring 32. The fixed component 2 further includes a connection ring 25. The connection ring 25 is fixedly installed at the outer ends of the first metal ring 31 and the second metal ring 32. The first metal ring 31 and the connection ring 25, and the second metal ring 32 and the connection ring 25 are integrally die-cast. The rubber sleeve 21 is wrapped around the outer side of the connection ring 25. The rubber sleeve 21 is wrapped and fixed on the outer side of the connection ring 25 by rubber injection molding.

[0033] The steel pipe 1 is internally connected to the rubber sleeve 21. The rubber sleeve 21 is interconnected with the corresponding first metal ring 31 and second metal ring 32. A plug plate 33 is fixedly installed on the side surface of the first metal ring 31. A slot 37 is formed inside the second metal ring 32. The plug plate 33 is inserted into the slot 37. A jack 34 is formed inside the plug plate 33. A screw 36 is inserted into the second metal ring 32. The screw 36 passes through the corresponding jack 34. The part of the screw 36 located outside the slot 37 is screwed inside the second metal ring 32. The part of the screw 36 located inside the slot 37 is inserted into the second metal ring 32. A knob 35 is fixedly installed at the outer end of the screw 36.

[0034] In this embodiment, when two steel pipes 1 are connected, after the rubber sleeve 21 is fixed, the insertion plate 33 is inserted into the slot 37 by aligning it. After insertion, the first metal ring 31 and the second metal ring 32 on both sides are aligned. A rubber pad is fixedly installed on the connection surface of the first metal ring 31 and the second metal ring 32 and on the side of the first metal ring 31. The rubber pad between the two seals the connection between the two. And after the insertion plate 33 is inserted, the screw 36 is screwed into the second metal ring 32. When screwing, the screw 36 is rotated by the knob 35 for screwing. When screwing, the screw 36 will be inserted into the jack 34. Thus, the insertion plate 33 is fixed inside the slot 37 through the screw 36, thereby realizing the fixation of the first metal ring 31 and the second metal ring 32, and further realizing the fixation of the two steel pipes 1 on both sides. And the use of multiple insertion plates 33 for fixation makes the fixation effect better and not easily separated.

[0035] At the same time, the content not described in detail in this specification belongs to the well-known prior art in the art.

[0036] Working principle: When the steel pipe 1 is connected to the rubber sleeve 21, first, the rubber sleeve 21 is sleeved on the outside of the corresponding steel pipe 1. After sleeving, the snap ring 23 is clamped between the grooves 22. After clamping, the bolt 24 is installed between the upper and lower snap rings 23 to fix the snap ring 23. After the snap ring 23 is fixed, the rubber sleeve 21 below is extruded by the extrusion force of the snap ring 23, and the extrusion position is inside the groove 22. The rubber layer at the groove 22 is thinner and can be deformed better and fit on the outside of the steel pipe 1 after being extruded, so as to better seal the connection between the steel pipe 1 and the rubber sleeve 21, greatly reducing the probability of leakage; when two steel pipes 1 are connected, after the rubber sleeve 21 is fixed, the insertion plate 33 is inserted into the slot 37 by aligning it. After insertion, the first metal ring 31 and the second metal ring 32 on both sides are aligned. A rubber pad is fixedly installed on the connection surface of the first metal ring 31 and the second metal ring 32 and on the side of the first metal ring 31. The rubber pad between the two seals the connection between the two. And after the insertion plate 33 is inserted, the screw 36 is screwed into the second metal ring 32. When screwing, the screw 36 is rotated by the knob 35 for screwing. When screwing, the screw 36 will be inserted into the jack 34. Thus, the insertion plate 33 is fixed inside the slot 37 through the screw 36, thereby realizing the fixation of the first metal ring 31 and the second metal ring 32, and further realizing the fixation of the two steel pipes 1 on both sides. And the use of multiple insertion plates 33 for fixation makes the fixation effect better and not easily separated.
