[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. 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.

[0016] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0017] Reference Figures 1 to 4 It can be seen that: a pipeline connection structure includes a container wall 1, a pipeline joint 2, a sealing ring 3, a retaining ring 4 and a positioning ring 5, the pipeline joint 2 is fixedly installed on the container wall 1, and a plurality of clamping claws 201 are evenly and fixedly connected on the side surface of one end of the pipeline joint 2 close to the container wall 1, and the plurality of clamping claws 201 can clamp the pipeline joint 2 into the through hole on the container wall 1, and the outer side and inner side of the clamping claw 201 are respectively provided with an outer clamping groove 202 and an inner clamping groove 203, and the pipeline joint 2 is fixedly installed on the container wall 1. It is fixed on the container wall 1 through the outer clamping groove 202, and a sealing ring 3 and a retaining ring 4 are installed between the pipe joint 2 and the container wall 1. The sealing ring 3 is sleeved on the outside of the outer clamping groove 202, and the sealing ring 3 is located on the inner side of the retaining ring 4. The retaining ring 4 can prevent the sealing ring 3 from being blown out by the internal pressure. The positioning ring 3 is clamped and installed in the inner clamping groove 203. The positioning ring 5 is fixedly installed in the inner clamping groove 203. The positioning ring 5 can prevent the clamping claw 201 from being retracted and causing the pipe joint 2 to fall off.

[0018] The pipe joint 2 is made of plastic, which is convenient for mass injection molding production and has a certain toughness and is easy to install; the sealing ring 3 is made of rubber material, which is elastic and has good sealing performance; the retaining ring 4 is made of plastic, which has low cost and is easy to produce; the positioning ring 5 is made of metal material, which has high strength and good stability, and can effectively prevent the clamping claw 201 from retracting and causing the pipe joint 2 to fall off.
