It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figure 1 to Figure 4 The utility model provides a grooveless pipe flange connector, comprising:

[0024] A central tube 1 is used to connect a pipeline, the pipeline can be inserted into the central tube 1, and the diameter of the central tube 1 is larger than the diameter of the pipeline;

[0025] The swivel 2 is rotatably arranged on the outer ring side wall of the center tube 1, and side rings 21 are arranged on the side walls on both sides of the swivel 2. Avoidance space is arranged between the inner ring side wall of the side ring 21 and the outer ring side wall of the center tube 1, and a number of reciprocating seats 22 are evenly arranged in the avoidance space. The reciprocating seats 22 are slidably connected to the outer ring side wall of the center tube 1, and the sliding directions of the reciprocating seats 22 are parallel to the axis of the center tube 1. The reciprocating seats 22 are provided with guide grooves 222 on the side away from the swivel 2, and guide columns (not shown in the figure) are provided on the side rings 21 to cooperate with the guide grooves 222. When the swivel 2 drives the side rings 21 to rotate, the reciprocating seats 22 can slide along the center tube 1 under the cooperation of the guide grooves 222 and the guide columns. A platform 221 is provided on the side of the reciprocating seat 22 away from the rotating ring 21, and a through groove is provided in the middle of the top surface of the platform 221. A plurality of first inner shafts 23 are rotatably penetrated on the side wall of the central tube 1, and the top ends of the first inner shafts 23 are inserted into the through grooves, and the ends of the first inner shafts 23 located in the through grooves are connected with first gears 231, and the side walls of one side of the through grooves are provided with first racks 231 meshing with the first gears 231, and the outside of the end of the first inner shaft 23 located inside the central tube 1 is sleeved with a first outer shaft 24, and the first inner shaft 23 is provided with a first spiral groove, and the first outer shaft 24 is provided with a first plug-in matching the first spiral groove, and the first plug-in is inserted into the first spiral groove, and the end of the first outer shaft 24 close to the axis of the central tube 1 is connected with a fixing ring 25.

[0026] The second inner shaft 3 and several second inner shafts 3 are rotatably arranged on the inner side wall of the center tube 1 at the rotating ring 2. The axis of the second inner shaft 3 is parallel to the axis of the center tube 1. The second inner shaft 3 is rotatably connected with a mounting seat (not shown in the figure), and the mounting seat is fixedly connected to the inner side wall of the center tube 1. The second inner shaft 3 is provided with a second gear 31, and the inner ring side wall of the rotating ring 2 is provided with several gear rings 27 meshing with the second gear 31.

[0030] During the implementation of the utility model, the user first inserts the pipe into the two ends of the central pipe 1 and makes the pipe abut against the sealing ring 33, then removes the pin and rotates the swivel 2. Under the cooperation of the guide groove 222 and the guide column, the reciprocating seat 22 moves in the direction away from the swivel 2. Under the action of the first gear 231 and the rack 223, a plurality of fixing rings 25 move synchronously to clamp and fix the pipe. At this time, the swivel 2 continues to rotate (the fixing ring 25 or the elastic pad produces elastic deformation), and the gear ring 27 meshes with the second gear 31, so that the two sealing rings 33 move toward the direction of the pipe, so that the sealing ring 33 and the pipe have an interference fit, thereby ensuring a good sealing effect.
