[0002] Different types of pipe joints are used to connect water pumps to pipelines. Among them, the pagoda joint is the most commonly used. Its structure generally consists of a threaded end and a pagoda end. A ring-shaped connecting ring is also provided around the pagoda joint to enhance the structural strength of the joint.

[0003] During the connection of water pump pipelines, the pagoda end and the pipeline adopt a nested connection method. During the nesting process, the pipeline and the pagoda end need to move axially until the pipeline is completely nested on the pagoda end to achieve a complete connection. Simple axial movement is time-consuming and labor-intensive, resulting in low pipeline assembly efficiency. Utility Model Content

The end face ring is nested in the pagoda connecting end along the sliding groove of the traction main pipe. The outer wall of the traction pipe section is provided with an external thread and a push screw ring that is threadedly connected to the external thread. The push screw ring pushes the end face ring to move through a spiral motion.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] This utility model embodiment provides a water pump connection assembly structure, such as Figures 1-5 As shown, the water pump connection assembly structure is applied to a pagoda connector 300. The pagoda connector 300 is existing technology. One end of the pagoda connector 300 is a pagoda connection end 320, and the other end is a threaded end 330. The threaded end 330 can be an external thread or an internal thread. This application uses an external thread structure for ease of demonstration. For specific details, refer to the above equipment structure and adopt a suitable thread structure. The threaded end 330 of the pagoda connector 300 is connected to the outlet of a water pump with a threaded opening. The pagoda connector 300 has a connecting ring 310 on its annular side. The water pump connection assembly structure includes:

[0029] A limiting ring 110 is provided at one end with a receiving cavity. The limiting ring 110 is nested in a connecting ring 310 provided on a pagoda connector 300. A limiting plate 130 is also provided around the receiving cavity. The limiting plate 130 slides on the side wall of the limiting ring 110. After the limiting ring 110 is nested in the connecting ring 310, the limiting plate 130 moves centripetally towards the axis of the limiting ring 110 and abuts against the end face of the connecting ring 310, thus fixing the limiting ring 110 and the connecting ring 310.

[0030] A traction pipe section 120 is provided, one end of which is connected to the limiting ring 110. A connecting pipe 200 is provided inside the traction pipe section 120. The connecting pipe 200 includes an end face ring 210 and a main pipe 220 connected to the end face ring 210. The main pipe 220 extends out of the traction pipe section 120 from the end away from the limiting ring 110. The end face ring 210 slides on a sliding groove 121 provided on the side wall of the traction pipe section 120.

[0031] The pagoda connector 300 has a pagoda connecting end 320 extending from one side of the limiting ring 110 into the traction pipe section 120. The end face ring 210 is nested in the traction main pipe 220 along the sliding groove 121. The outer wall of the traction pipe section 120 has an external thread 122 and a push screw ring 123 threadedly connected to the external thread 122. Due to the fixation of the limiting ring 110 and the connecting ring 310, when the push screw ring 123 moves spirally, the end face ring 210 can only move closer to the limiting ring 110, while the pagoda connecting end 320 will continuously extend into the main pipe 220 during the movement.

[0032] The number of sliding grooves 121 is at least two sets. The end face ring 210 is provided with sliding blocks 230 that are adapted to the number of sliding grooves 121. Part of the structure of the sliding block 230 extends out of the side wall of the traction tube section 120 through the sliding groove 121. The pushing screw ring 123 is in contact with the part of the sliding block 230 extending out of the side wall of the traction tube section 120.

[0033] In this embodiment, the main pipe 220 is the main water supply pipeline, and the end face ring 210 is equivalent to a connecting flange. In the pagoda joint structure, the limiting ring 110, the traction pipe section 120 and the pushing screw ring 123 cooperate to limit the main pipe 220 and the pagoda connection end 320 to a certain extent, reducing the subsequent fixing structure between the pipe fitting and the pagoda connection end 320. Furthermore, by cooperating with the end face ring 210, the simple axial pushing of the nested work of the main pipe 220 and the pagoda connection end 320 is transformed into a screwing action, making the nested assembly easier to operate and improving the assembly efficiency.

[0034] In a preferred embodiment of this invention, the circumference of the limiting ring 110 is provided with a plurality of limiting grooves 101 penetrating the sidewall of the limiting ring 110, the limiting plate 130 slides in the limiting grooves 101, the limiting ring 110 is also provided with locking screw holes 102, the locking screw holes 102 communicate with the limiting grooves 101, and the locking bolts 140 provided in the locking screw holes 102 abut against the limiting plate 130;

[0035] In this embodiment, the limiting slide groove 101 has receiving cavities at both ends, and the limiting plate 130 has limiting protrusions at both ends. The limiting protrusions are housed in the receiving cavities when the limiting plate 130 moves. The limiting protrusions prevent the limiting plate 130 from slipping out of the limiting slide groove 101. The inner diameter of the limiting ring 110 is adapted to the outer diameter of the connecting ring 310 of the pagoda connector 300. In order to allow the limiting plate 130 to be completely housed in the limiting slide groove 101, receiving cavities that can accommodate the limiting protrusions are provided on both sides of the limiting slide groove 101 to prevent the limiting plate 130 from interfering with the nesting action.

[0036] In a preferred embodiment of this invention, the side of the end face ring 210 away from the main pipe 220 is a flared opening, and the pagoda connection end 320 on the pagoda connector 300 is inserted from the side of the end face ring 210 away from the main pipe 220.

[0037] In this embodiment, the pagoda connector 320 is easily inserted with the help of the flared opening, and the diameter of the main pipe 220 is adapted to the pagoda connector 320. To ensure sealing, the length of the traction pipe section 120 can be less than the length of the pagoda connector 320, so that the pagoda connector 320 can be inserted into the part of the main pipe 220 located outside the traction pipe section 120. A sealing locking ring is separately set on this part to lock the pagoda connector 320 and the main pipe 220, thereby improving the sealing effect.
