This technical solution solves the problems mentioned in the background art, such as the lack of a dedicated joint device, which makes the water pipe connection process difficult to operate, time-consuming, and often results in water leakage due to poor fit at the water pipe connection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-connection device for downhole water pipe joints includes an upper connector and a lower connector. The upper connector and the lower connector are snapped together by a snap-fit ​​block and a snap-fit ​​piece. A sealing ring is provided inside the top of the lower connector through a sealing groove. The inner side of the sealing ring is provided with snap teeth through a snap ring. A pressure ring is provided at the top of the snap ring.

[0007] Preferably, the upper connector has an upper threaded sleeve inside its top end, and four sets of snap-fit ​​blocks are provided on the outer surface of the upper connector, with a sliding groove opened on the outer surface of the top end of each of the four sets of snap-fit ​​blocks.

[0008] Preferably, the bottom end of the lower connector is provided with a lower threaded sleeve, and the outer surface of the lower connector is provided with four sets of snap-fit ​​parts. The inner side of each of the four sets of snap-fit ​​parts is provided with a snap-fit ​​groove, and the inside of the snap-fit ​​groove is in contact with the outer surface of the snap-fit ​​block.

[0009] Preferably, the lower connector has a positioning ring at its top end, and the positioning ring is located in a positioning groove at the bottom end of the upper connector.

[0010] Preferably, the upper threaded sleeve and the lower threaded sleeve at the ends of the upper connector and the lower connector are both connected to the water pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] First, the quick locking of the snap-fit ​​blocks and snap-fit ​​parts enables tool-free installation of the water pipe joint, improving the efficiency of operations in confined downhole spaces. Second, the limiting effect of the pressure ring on the snap ring ensures uniform engagement of the snap-fit ​​teeth with the outer wall of the water pipe, avoiding sealing failures caused by uneven manual tightening. Third, the guiding cooperation between the positioning ring and the positioning groove enables automatic alignment during connection, avoiding the risk of leakage caused by misalignment. Finally, the circumferentially distributed characteristics of the four sets of snap-fit ​​blocks ensure isotropic pull-out resistance of the joint, guaranteeing connection reliability under complex working conditions.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1-4 As shown, the upper connector 1 and the lower connector 2 are snapped together by the snap-fit ​​block 102 and the snap-fit ​​piece 202. The top of the lower connector 2 is provided with a sealing ring 3 through a sealing groove. The inner side of the sealing ring 3 is provided with a snap tooth 303 through a snap ring 302. The top of the snap ring 302 is provided with a pressure ring 301.

[0023] In this solution, the elastic deformation characteristics of the sealing ring 3 achieve a dynamic sealing effect on the outer wall of the water pipe, the uniform distribution of the retaining teeth 303 achieves multi-point interlocking and fixing of the water pipe, significantly enhancing the pull-out resistance, and the axial pressing action of the pressure ring 301 achieves the radial shrinkage effect of the retaining ring 302.

[0024] Reference Figure 3-4 As shown, the upper connector 1 has an upper threaded sleeve 101 inside its top end, and four sets of snap-fit ​​blocks 102 are provided on the outer surface of the upper connector 1. The top outer surface of each of the four sets of snap-fit ​​blocks 102 is provided with a sliding groove 103. The upper threaded sleeve 101 and the lower threaded sleeve 201 at the ends of the upper connector 1 and the lower connector 2 are both connected to the water pipe.

[0025] In this scheme, the symmetrical ring arrangement of four sets of snap-fit ​​blocks 102 achieves the automatic adjustment function of the preload of snap-fit ​​blocks 102 and snap-fit ​​parts 202 through the guiding effect of the inclined plane.

[0026] Reference Figure 2 As shown, a lower threaded sleeve 201 is provided inside the bottom end of the lower connector 2, and four sets of snap-fit ​​parts 202 are provided on the outer surface of the lower connector 2. Each of the four sets of snap-fit ​​parts 202 has a snap-fit ​​groove 203 on its inner side. The inside of the snap-fit ​​groove 203 fits against the outer surface of the snap-fit ​​block 102. A positioning ring 204 is provided at the top of the lower connector 2. The positioning ring 204 is located in the positioning groove 104 opened at the bottom end of the upper connector 1.

[0027] In this solution, the elastic cantilever structure of the snap-fit ​​component 202 achieves a one-way unlocking effect during disassembly. At the same time, by setting the snap-fit ​​block 102, the mechanical interlocking function in the connected state is achieved through the slide groove 103.

[0028] The working principle of this utility model is as follows: First, the upper threaded sleeve 101 and the lower threaded sleeve 201 are respectively connected to the water pipe to ensure smooth fluid transmission. The snap-fit ​​block 102 of the upper connector 1 is embedded in the snap-fit ​​part 202 of the lower connector 2. The sliding groove 103 and the snap-fit ​​groove 203 cooperate to form an interlock to ensure a stable connection. At the same time, the positioning ring 204 cooperates with the positioning groove 104 to ensure that the upper connector 1 and the lower connector 2 are accurately aligned to avoid misalignment during installation. Second, the sealing ring 3 is compressed and undergoes elastic deformation, which tightly fits the outer wall of the water pipe to achieve dynamic sealing and prevent fluid leakage. The snap-fit ​​teeth 303 of the snap ring 302 evenly bite the surface of the water pipe, and the pressure ring 301 applies axial pressure to make the snap ring 302 radially contract, thereby enhancing the water pipe's pull-out resistance.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
