Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] In this embodiment of the utility model, please refer to Figures 1 to 4 A plastic water pipe connection device includes a water pipe body 1, and further includes:

[0039] The abutment ring 2 abuts against the ends of the two sets of water pipe bodies 1 on both sides respectively;

[0040] The inner wall of the retaining ring 4 is connected to the outer wall of the abutting ring 2;

[0041] The fixing mechanism has one end abutting against the water pipe body 1 and is used to fix the water pipe body 1.

[0042] The docking mechanism is connected to the fixing ring 4 at one end and to the fixing mechanism at the other end, and is used to drive the two sets of water pipe bodies 1 to move closer to each other.

[0043] Two sets of water pipe bodies 1 are placed on both sides of the abutment ring 2. The water pipe bodies 1 are fixed by the fixing mechanism. The two sets of water pipe bodies 1 are brought closer to each other by the docking mechanism, so that the ends of the water pipe bodies 1 abut against the abutment ring 2, and the two sets of water pipe bodies 1 are connected.

[0044] As one embodiment of this utility model, please refer to Figure 1 , Figure 2 and Figure 4 The docking mechanism includes:

[0045] Slot 5 is located on the fixing ring 4;

[0046] Rotating ring 8 is rotatably connected to fixed ring 4;

[0047] Threaded ring 9 is connected to rotating ring 8;

[0048] Threaded folding ring 10 is threadedly connected to threaded ring sleeve 9;

[0049] The positioning ring 7 is connected to the threaded folding ring 10;

[0050] The lever 6 is connected to the positioning ring 7 and is slidably engaged with the slot 5.

[0051] When the locking rod 6 and the locking groove 5 are slidably engaged, and the two sets of water pipe bodies 1 need to be connected, the threaded ring sleeve 9 is rotated. Under the limit of the locking rod 6 and the locking groove 5, the threaded ring sleeve 9 drives the threaded folding ring 10 to move laterally. The threaded folding ring 10 drives the two sets of positioning rings 7 to move closer to each other, and then drives the two sets of water pipe bodies 1 to move closer to each other, so that the end of the water pipe body 1 abuts against the abutting ring 2, and the connection is completed.

[0052] As one embodiment of this utility model, please refer to Figures 1 to 4 The fixing mechanism includes:

[0053] A threaded annular groove 11 is formed on the locating ring 7;

[0054] Threaded ring 12 is threadedly connected to threaded ring groove 11;

[0055] Rotate the folding ring 13 to connect it with the threaded ring 12;

[0056] The abutment component is connected at one end to the positioning ring 7 and at the other end to the rotating folding ring 13.

[0057] Rotating the rotating folding ring 13 causes the threaded ring 12 to be threadedly connected to the threaded ring groove 11, resulting in synchronous lateral movement of the rotating folding ring 13 during rotation. The rotating folding ring 13 drives the abutting component to move, causing the abutting component to abut against the outer wall of the water pipe body 1, thereby fixing the water pipe body 1.

[0058] As one embodiment of this utility model, please refer to Figures 1 to 4 The abutment component includes:

[0059] The inclined plate ring 14 is connected to the rotating folding ring 13 at one end, and the other end of the inclined plate ring 14 is a beveled structure on the side near the water pipe body 1.

[0060] A sliding groove 15 is formed on the positioning ring 7;

[0061] The sliding rod 16 is slidably engaged with the sliding groove 15;

[0062] The abutting inclined block 17 is connected to the bottom end of the sliding rod 16. The bottom of the abutting inclined block 17 abuts against the side wall of the water pipe body 1. The side of the grounding inclined block 17 away from the water pipe body 1 is a slanted structure.

[0063] Rotating the folding ring 13 causes the threaded ring 12 to be threadedly connected to the threaded ring groove 11, resulting in synchronous lateral movement of the folding ring 13 during rotation. The folding ring 13 drives the inclined plate ring 14 to move laterally, and one side of the inclined plate ring 14 abuts against one side of the inclined block 17. Under the limitation of the sliding rod 16 and the sliding groove 15, the inclined block 17 moves towards the side closer to the water pipe body 1, thereby making the inclined block 17 tightly abut against the side wall of the water pipe body 1 and fixing the water pipe body 1.

[0064] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 It also includes:

[0065] The sealing ring gasket 3 is connected to the abutment ring 2 and abuts against the water pipe body 1.

[0066] The sealing ring gasket 3 is installed between the abutment ring 2 and the water pipe body 1. Through the squeezing action of the abutment ring 2, the sealing ring gasket 3 is tightly fitted to the end of the water pipe body 1 to form the first seal. When the docking mechanism drives the two sets of water pipe bodies 1 to approach each other, the end of the water pipe body 1 further squeezes the sealing ring gasket 3 to enhance the sealing effect.

[0067] The working principle of this utility model is as follows: During installation, firstly, place the two sets of water pipe bodies 1 on both sides of the abutment ring 2, install the sealing ring gasket 3 on the abutment ring 2, and slide the locking rod 6 into the locking groove 5 on the fixing ring 4.

[0068] The threaded ring 12 is threadedly connected to the threaded ring groove 11 on the positioning ring 7. By rotating the rotating folding ring 13, the rotating folding ring 13 drives the inclined plate ring 14 in the abutment assembly to move laterally. One side of the inclined plate ring 14 abuts against one side of the inclined block 17. Under the limitation of the sliding rod 16 and the sliding groove 15, the abutment block 17 moves towards the side closer to the water pipe body 1, so that the abutment block 17 abuts tightly against the side wall of the water pipe body 1, and fixes the water pipe body 1.

[0069] Rotating the threaded ring 9 causes the threaded folding ring 10 to move axially. The movement of the threaded folding ring 10 causes the positioning ring 7 to move axially, ultimately bringing the two sets of water pipe bodies 1 closer together and completing the connection.

[0070] The sealing ring gasket 3 is installed between the abutment ring 2 and the water pipe body 1. Through the squeezing action of the abutment ring 2, the sealing ring gasket 3 is tightly fitted to the end of the water pipe body 1 to ensure the sealing effect.
