[0002] At present, when docking HDPE pipe bodies, most of them are docked by hot melt welding. Before hot melt welding, it is necessary to prepare wires, hot melt welding machines, cutting tools (such as milling devices), cleaning tools (such as cleaning cloths), etc. During hot melt welding, first fix the ends of two HDPE pipe bodies on the fixed brackets and sliding brackets of the hot melt welding machine; then use cutting tools and cleaning tools to correct and clean the ports of the two HDPE pipe bodies so that the ports of the two HDPE pipe bodies can be flat against each other; then place the heating plate; then make the ports of the two HDPE pipe bodies adhere to the heating surface of the heating plate to heat the ports of the two HDPE pipe bodies to a softened state through the heating plate; then remove the heating plate, operate the sliding bracket, and make the port of the HDPE pipe body on the sliding bracket tightly press on the port of the other HDPE pipe body so that the ports of the two HDPE pipe bodies are fused together; then cool for more than half an hour; only then can the docking of the two HDPE pipe bodies be truly realized. Docking HDPE pipe bodies in this way not only requires preparing more tools, but also greatly tests the experience and patience of operators, and it takes a lot of time to complete the docking of HDPE pipe bodies. This docking method is prone to problems such as high requirements for the docking environment, unstable docking quality, and low docking efficiency, which will lead to unstable construction quality and long construction periods of related projects.

[0003] Therefore, it is very necessary to design an HDPE pipe body to solve the above technical problems. Summary of the Utility Model

Moreover, it has low requirements for the docking environment, very stable docking quality, and very high docking efficiency, so as to greatly improve the construction quality of related projects and shorten the construction period.

[0005] The technical solution of the utility model is realized as follows:

[0006] An HDPE pipe body, characterized in that it includes a pipe body. A plurality of elastic buckling pieces are arranged on the outer circumferential surface of the end of the pipe body, and each elastic buckling piece inclines towards the middle direction of the pipe body.

[0027] As Figures 1 to 4 shown, a kind of HDPE pipe body described in the present utility model includes a pipe body 1. A plurality of elastic deduction pieces 11 are arranged on the outer circumferential surface at the end of the pipe body 1, and each elastic deduction piece 11 is inclined towards the middle direction of the pipe body 1. A sealing rubber ring 2 is sleeved on the pipe body 1, and the sealing rubber ring 2 is located on the side of the elastic deduction piece 11 away from the port of the pipe body 1.

[0028] On this HDPE pipe body, by arranging a plurality of elastic deduction pieces 11 on the outer circumferential surface at the end of the pipe body 1 and making each elastic deduction piece 11 inclined towards the middle direction of the pipe body 1; this can not only facilitate the installation of the pipe body 1, but also utilize the elastic deduction pieces 11 to play a stable and reliable deduction role after installation, which is beneficial to improving the convenience and stability of the docking of the HDPE pipe body.

[0029] The sealing rubber ring 2 is sleeved on the pipe body 1, and the sealing rubber ring 2 is located on the side of the elastic deduction piece 11 away from the port of the pipe body 1; this can achieve a sealing effect after installation, thereby being beneficial to improving the sealing performance of the docking of the HDPE pipe body.

[0030] Thus, when the HDPE pipe bodies are butt-jointed, the butt-joint of the HDPE pipe bodies can be realized through nesting operation. This not only facilitates the quick and stable butt-joint of two HDPE pipe bodies, but also reduces the usage amount of tools during the butt-joint process. Its butt-joint operation is very simple and easy to quickly achieve the butt-joint. It has low requirements for the butt-joint environment, very stable butt-joint quality, and very high butt-joint efficiency, thus facilitating greatly improving the construction quality of related projects and shortening the construction period.

[0031] As Figure 2 shown in Figure 4 , a steel inner cylinder 3 is embedded in the end of the pipe body 1, and the steel inner cylinder 3 is arranged around the inner hole of the pipe body 1. This can achieve the purpose of improving the structural strength and durability of the pipe body 1, and enable the pipe body 1 to have very high compressive capacity, thereby helping to further improve the reliability and service performance of the pipe body 1.

[0032] As Figure 2 , Figures 4 to 6 shown, each elastic buckling piece 11 is connected to one end of the steel inner cylinder 3 close to the port of the pipe body 1. This can make the installation position of the elastic buckling piece 11 have high structural strength, thus facilitating improving the stability and reliability of the installation and positioning of the elastic buckling piece 11, and further enabling the elastic buckling piece 11 to play a more stable and reliable buckling effect, which helps to further improve the reliability and applicability of the pipe body 1.

[0033] As Figure 6 shown, the elastic buckling piece 11 and the end of the steel inner cylinder 3 are connected in an arc transition. This can not only make the connection very stable and reliable, but also enable the elastic buckling piece 11 to have better elastic contraction and elastic buckling effects, thereby helping to further improve the service performance of the pipe body 1.

[0034] As Figures 4 to 6 shown, each elastic buckling piece 11 and the steel inner cylinder 3 are of an integral stainless steel structure. This can not only facilitate manufacturing, but also improve the structural strength and durability, thereby helping to further improve the reliability and service life of the pipe body 1.

[0035] As Figure 1 shown in Figure 2 and

[0036] As Figure 1 , Figure 2 shown in Figure 7As shown, the two end faces of the sealing rubber ring 2 are inclined surfaces 21 with the same inclination direction as that of the elastic buckling piece 11. This can play a more stable and reliable blocking and positioning role, thus helping to further improve the reliability of the HDPE pipe body.

[0037] As Figures 8 to 11 shown, when actually docking two HDPE pipe bodies, the following sleeve pipe 4 is used to achieve it. Specifically: the inner hole of the sleeve pipe 4 forms a socket hole 41, and buckling spring piece groups 5 are respectively arranged on the hole walls at both ends of the socket hole 41. The buckling spring piece groups 5 include several buckling spring pieces 51, and each buckling spring piece 51 is arranged in an annular array around the axial center line of the socket hole 41 and makes each buckling spring piece 51 incline towards the center direction of the socket hole 41. During docking, first, the sealing rubber ring 2 is sleeved on the pipe body 1 and the sealing rubber ring 2 passes through the elastic buckling piece 11; then the end of the pipe body 1 is embedded in one end of the socket hole 41. In this process, each elastic buckling piece 11 and each buckling spring piece 51 in one end of the socket hole 41 are compressed and contracted, and each elastic buckling piece 11 is placed inside the socket hole 41 after passing through the buckling spring piece 51. At this time, each elastic buckling piece 11 elastically presses against the hole wall of the socket hole 41, and the corresponding buckling spring piece 51 elastically presses against the outer wall of the pipe body 1; then, a rod-shaped tool is used to push the sealing rubber ring 2 between the elastic buckling piece 11 and the buckling spring piece 51. At this time, both ends of the sealing rubber ring 2 elastically press against the elastic buckling piece 11 and the buckling spring piece 51 respectively, and the inner and outer walls of the sealing rubber ring 2 elastically press against the outer wall of the pipe body 1 and the inner wall of the socket hole 41 respectively; in this way, one pipe body 1 is docked with the HDPE pipe body. The other pipe body 1 is also docked in the same way. In this way, the two pipe bodies 1 can be quickly and stably docked together, and during the docking process, few tools are used, the operation is simple, and it is easy to quickly achieve docking. Moreover, the requirements for the docking environment are low, the docking quality is very stable, and the docking efficiency is very high. This can not only effectively limit the sliding of the sleeve pipe 4, but also use the elastic force of the two sealing rubber rings 2 to make the ports of the two pipe bodies 1 stably stick together tightly, which can ensure that the docking part will not come off and leak water during long-term use, thus helping to greatly improve the construction quality of relevant projects and shorten the construction period.

[0038] As Figure 9 and Figure 11 shown, the sleeve pipe 4 is a pipe made of HDPE material, and a steel cylinder 6 is buried in the sleeve pipe 4 and the steel cylinder 6 is arranged around the socket hole 41. This can achieve the purpose of improving the structural strength and durability of the sleeve pipe 4, and enable the sleeve pipe 4 to have a very high compressive capacity, thus helping to further improve the reliability and service performance of the sleeve pipe 4.

[0039] As Figure 9 、 Figures 11 to 13As shown, the buckling elastic pieces 51 of the two groups of buckling elastic piece groups 5 are respectively connected to both ends of the steel cylinder 6. This can make the installation position of the buckling elastic pieces 51 have high structural strength, thus facilitating the improvement of the stability and reliability of the installation and positioning of the buckling elastic pieces 51, and further facilitating the buckling elastic pieces 51 to exert a more stable and reliable buckling effect, which helps to further improve the reliability and applicability of the sleeve pipe 4.

[0040] As Figure 13 shown, the buckling elastic piece 51 and the end of the steel cylinder 6 are connected with an arc transition. This can not only make the connection very stable and reliable, but also make the buckling elastic piece 51 have better elastic contraction and elastic buckling effect, thus helping to further improve the service performance of the sleeve pipe 4.

[0041] As Figure 13 shown, the steel cylinder 6 and each buckling elastic piece 51 are of an integral stainless steel structure. This can not only facilitate manufacturing, but also improve structural strength and durability, thus helping to further improve the reliability and service life of the sleeve pipe 4.

[0042] As Figure 9 shown, the inner wall of the buckling elastic piece 51 presses against the corresponding inclined surface 21. This can not only make the structure relatively simple, but also use the buckling elastic piece group 5 to play a role in blocking and positioning the sealing rubber ring 2, so that the sealing rubber ring 2 can exert a more stable and reliable sealing effect, and further help to improve the service performance of the sleeve pipe 4.

[0043] As Figure 9 shown, the inclination direction of the buckling elastic piece 51 is the same as that of the inclined surface 21 it presses against. This can play a more stable and reliable role in blocking and positioning, thus helping to further improve the reliability of the sleeve pipe 4.

[0044] A waterproof rubber ring (not shown in the figure) is installed between the orifice of the socket hole 41 and the pipe body 1. This can prevent water and soil from directly contacting the buckling elastic pieces 51, thus playing a role in protecting the buckling elastic pieces 51, and further helping to extend the service life.
