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 pipes 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 pipes so that the ports of the two HDPE pipes can be flat against each other; then place the heating plate; then make the ports of the two HDPE pipes cover on the heating surface of the heating plate to heat the ports of the two HDPE pipes 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 on the sliding bracket tightly press on the port of the other HDPE pipe so that the ports of the two HDPE pipes are fused together; then cool for more than half an hour; only then can the docking of the two HDPE pipes be truly realized. Docking HDPE pipes 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 pipes. 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.

[0025] As Figures 1 to 3 shown, a kind of HDPE pipe joint structure described in the present utility model includes a sleeve pipe 1. The inner hole of the sleeve pipe 1 forms a socket hole 11. Deduction elastic sheet groups 2 are respectively arranged on the hole walls at both ends of the socket hole 11. The deduction elastic sheet groups 2 include a plurality of deduction elastic sheets 21. Each deduction elastic sheet 21 is arranged in a circular array around the axial center line of the socket hole 11, and each deduction elastic sheet 21 inclines towards the center direction of the socket hole 11. At least two sealing rubber rings 3 are embedded in the socket hole 11 between the two deduction elastic sheet groups 2.
[0026] In the structure of this HDPE pipe joint, the socket hole 11 can be used to socket two HDPE pipes to be butt - jointed, and the two sets of buckling spring - piece groups 2 can conveniently buckle the two HDPE pipes. The buckling spring pieces 21 are arranged in an annular array around the axial center line of the socket hole 11, and each buckling spring piece 21 inclines towards the center of the socket hole 11. This can not only greatly facilitate the sleeving, but also help the buckling spring - piece group 2 play a more stable and reliable buckling role, which is beneficial to improving the convenience and stability of the HDPE pipe butt - joint.
[0027] By installing at least two sealing rubber rings 3 in the socket hole 11 between the two buckling spring - piece groups 2, it is beneficial to achieve a two - way sealing effect, so as to ensure good sealing effects between the two HDPE pipes and the sleeve pipe 1, which is beneficial to improving the reliability of the HDPE pipe butt - joint.
[0028] Therefore, when the HDPE pipe joint structure is butt - jointed, the butt - joint of the HDPE pipes can be achieved through the nesting operation. This can not only quickly and stably butt - joint the two HDPE pipes together, but also reduce 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, so it is beneficial to greatly improve the construction quality of related projects and shorten the construction period.
[0029] Such as Figure 2 and Figure 3 As shown, the sleeve pipe 1 is a pipe made of HDPE material, and a steel cylinder 12 is embedded in the sleeve pipe 1, and the steel cylinder 12 is arranged around the socket hole 11. This can improve the structural strength and durability of the HDPE pipe joint structure, and enable the HDPE pipe joint structure to have a very high compressive capacity, thus contributing to further improving the reliability and service performance of the HDPE pipe joint structure.
[0030] Such as Figures 2 to 5 As shown, the buckling spring pieces 21 of the two buckling spring - piece groups 2 are respectively connected to the two ends of the steel cylinder 12. This can make the installation position of the buckling spring pieces 21 have high structural strength, thus being beneficial to improving the stability and reliability of the installation and positioning of the buckling spring pieces 21, and further being beneficial to making the buckling spring pieces 21 play a more stable and reliable buckling effect, which helps to further improve the reliability and applicability of the HDPE pipe joint structure.
[0031] Such as Figures 2 to 5 As shown, the buckling spring piece 21 and the end of the steel cylinder 12 are connected with an arc transition. This can not only make the connection very stable and reliable, but also enable the buckling spring piece 21 to have better elastic contraction and elastic buckling effects, thus contributing to further improving the service performance of the HDPE pipe joint structure.
[0032] As Figures 2 to 5 shown, the steel cylinder 12 and each buckling spring piece 21 are of an integral stainless steel structure. This not only facilitates manufacturing, but also improves the structural strength and durability, thus contributing to further enhancing the reliability and service life of the HDPE pipe joint structure.
[0033] As Figure 1 and Figure 2 shown, there are two sealing rubber rings 3, and the two sealing rubber rings 3 are respectively abutted against the inner walls of the buckling spring pieces 21 of the two buckling spring piece groups 2. This not only makes the structure relatively simple, but also enables the buckling spring piece group 2 to play a role in blocking and positioning the sealing rubber rings 3, so that the sealing rubber rings 3 can achieve a more stable and reliable sealing effect, and further contributes to enhancing the service performance of the HDPE pipe joint structure.
[0034] As Figure 2 shown, the end face of the sealing rubber ring 3 abutted against the buckling spring piece 21 and the end face thereof away from the buckling spring piece 21 are both in the same inclination direction as that of the buckling spring piece 21. This can play a more stable and reliable role in blocking and positioning, thus contributing to further enhancing the reliability of the HDPE pipe joint structure.
[0035] As Figures 6 to 9As shown, during actual use, this HDPE pipe joint structure is used to butt against the following HDPE pipe 4. A number of elastic buckling pieces 41 are provided on the outer circumferential surface of the end of the HDPE pipe 4, and each elastic buckling piece 41 is inclined towards the middle of the HDPE pipe 4. During butting, first, the sealing rubber ring 3 is sleeved on the HDPE pipe 4, and the sealing rubber ring 3 passes through the elastic buckling pieces 41; then the end of the HDPE pipe 4 is inserted into one end of the socket hole 11. During this process, each elastic buckling piece 41 and each buckling elastic piece 21 in one end of the socket hole 11 are compressed and contracted, and each elastic buckling piece 41 is placed inside the socket hole 11 after passing through the buckling elastic piece 21. At this time, each elastic buckling piece 41 elastically presses against the hole wall of the socket hole 11, and the corresponding buckling elastic piece 21 elastically presses against the outer wall of the HDPE pipe 4; then, using a rod-shaped tool, the sealing rubber ring 3 is pushed between the elastic buckling piece 41 and the buckling elastic piece 21. At this time, both ends of the sealing rubber ring 3 elastically press against the elastic buckling piece 41 and the buckling elastic piece 21 respectively, and the inner and outer walls of the sealing rubber ring 3 elastically press against the outer wall of the HDPE pipe 4 and the inner wall of the socket hole 11 respectively; in this way, one HDPE pipe 4 is butted against the HDPE pipe joint structure. Another HDPE pipe 4 is butted in the same way. In this way, the two HDPE pipes 4 can be quickly and stably butted together by using the HDPE pipe joint structure. This can quickly and stably butt the two HDPE pipes together, and during the butting process, few tools are used, the operation is simple, and it is easy to quickly achieve butting. Moreover, the requirements for the butting environment are low, the butting quality is very stable, and the butting efficiency is very high. This can not only effectively limit the sliding of the HDPE pipe joint structure, but also use the elastic force of the two sealing rubber rings 3 to make the ports of the two HDPE pipes 4 tightly stick together stably, which can ensure that the butted part will not come off and leak water during long-term use, thereby greatly improving the construction quality of related projects and shortening the construction period.
[0036] As Figure 7 with Figure 9 As shown, a steel inner cylinder 42 is buried in the end of the HDPE pipe 4, and the steel inner cylinder 42 is arranged around the inner hole of the HDPE pipe 4. This can achieve the purpose of improving the structural strength and durability of the HDPE pipe 4, and enable the HDPE pipe 4 to have a very high compressive capacity, thereby helping to further improve the reliability and service performance of the HDPE pipe 4.
[0037] As Figure 7 and Figures 9 to 11As shown, each elastic offset piece 41 is connected to one end of the steel inner cylinder 42 close to the port of the HDPE pipe 4. This can make the installation position of the elastic offset piece 41 have high structural strength, so as to facilitate improving the stability and reliability of the installation and positioning of the elastic offset piece 41, and further facilitate making the elastic offset piece 41 play a more stable and reliable offset effect, which helps to further improve the reliability and applicability of the HDPE pipe 4.
[0038] As Figure 7 , Figures 9 to 11 shown, the end of the elastic offset piece 41 and the steel inner cylinder 42 are connected with an arc transition. This can not only make the connection very stable and reliable, but also make the elastic offset piece 41 have better elastic contraction and elastic offset effect, thus helping to further improve the service performance of the HDPE pipe 4.
[0039] As Figure 7 , Figures 9 to 11 shown, each elastic offset piece 41 and the steel inner cylinder 42 are of an integral stainless steel structure. This can not only facilitate manufacturing, but also improve the structural strength and durability, thus helping to further improve the reliability and service life of the HDPE pipe 4.
[0040] A waterproof rubber ring (not shown in the figure) is installed between the orifice of the socket hole 11 and the HDPE pipe 4. This can prevent water and soil from directly contacting the offset spring piece 21, so as to play a role in protecting the offset spring piece 21, and further facilitate extending the service life.
