[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 、 Figure 2, an embodiment provided by the present utility model: an electromagnetic heating type electrofusion fitting, including a first support plate 1, the upper surface of the first support plate 1 is fixedly connected with a second support plate 2, the upper surface of the second support plate 2 is fixedly connected with a first connecting shaft 3, the outer wall of the first connecting shaft 3 is rotatably connected with a first connecting disk 4, the inner wall of the first connecting disk 4 is slidably connected to the outer wall of the first connecting shaft 3, one side of the first connecting shaft 3 is fixedly connected with a first connecting block 5, one side of the first connecting block 5 is fixedly connected with a telescopic rod 7, one end of the telescopic rod 7 is fixedly connected with a second connecting block 6, and one end of the second connecting block 6 is fixedly connected to one side of the first connecting disk 4.

A first pipe fitting 8 is slidably connected inside the first connecting shaft 3, a fixing disk 18 is fixedly connected to the outer wall of the first pipe fitting 8, and a combination component is arranged at one end of the first pipe fitting 8;

[0024] Specifically, rotating the handle 15 drives the third connecting block 13 connected to the connecting plate 14, and the first rotating shaft 12 connected to the third connecting block 13 will rotate together. Then, the gear 10 connected to the first rotating shaft 12 will rotate. Subsequently, the gear 10 will drive the rack 9 to rotate, and the first connecting disk 4 connected to the rack 9 will rotate. The second connecting block 6 on the first connecting disk 4 will drive the connected telescopic rod 7 to rotate together, and the second rotating shaft 16 on the first connecting disk 4 will drive the second connecting shaft 17 to rotate together with the first connecting disk 4 to achieve the effect of clamping and fixing the combination of pipe fittings.

[0025] Referring to Figure 1 , Figure 3 , the combination component includes a third connecting shaft 19, one end of the third connecting shaft 19 is slidably connected with a first pipe fitting 8, a third rotating shaft 21 is rotatably connected inside the third connecting shaft 19, the outer wall of the third rotating shaft 21 is rotatably connected inside the third connecting shaft 19, a baffle 22 is fixedly connected to the outer wall of the third rotating shaft 21, and a rotating disk 20 is fixedly connected to one end of the third rotating shaft 21

[0026] Specifically, connect the third connecting shaft 19 to the first pipe fitting 8. Since the first pipe fitting 8 is provided with a fixing disk 18, it can be threadedly connected to the third connecting shaft 19. Subsequently, rotate the rotating disk 20 on the third rotating shaft 21 connected inside the third connecting shaft 19 to make it rotate. Then, the third rotating shaft 21 will also rotate accordingly, and the baffle 22 connected to the third rotating shaft 21 will close, resulting in the effect of preventing the liquid inside the pipe fitting from entering.

[0027] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS. Figure 1 , Figure 2 and Figure 4 , a fitting two 31 is fixedly connected inside a fitting one 8. A connecting column one 27 is fixedly connected to the outer wall of the fitting two 31. A sealing ring two 30 is fixedly connected to the inner wall of the connecting column one 27. The inner wall of the connecting column one 27 is fixedly connected to the outer wall of the fitting two 31. A connecting column two 32 is fixedly connected to the upper surface of the connecting column one 27. A spring 28 is sleeved on the outer wall of the connecting column two 32. A steel ball 26 is arranged inside the connecting column two 32. The upper surface of the steel ball 26 is slidably connected to an outer shell two 29. The outer wall of the outer shell two 29 is fixedly connected to an outer shell one 25. A connecting pipe 23 is slidably connected inside the outer shell one 25. A groove is formed inside the connecting pipe 23. A sealing ring one 24 is fixedly connected to the outer wall of the connecting pipe 23;

[0028] Specifically, when the outer shell one 25 is pushed to move the outer shell two 29 connected inside the outer shell one 25 downward together, after the outer shell two 29 originally above the steel ball 26 moves downward, the steel ball 26 will unlock because there is no pressing effect, and then the connecting pipe 23 connected inside the outer shell one 25 can be pulled out to replace the fitting. After the replacement, the connecting pipe 23 is reset and then the outer shell one 25 is released. After the extrusion force received by the outer shell one 25 from the downward push disappears, it will rebound to reset the outer shell one 25. After the outer shell one 25 is reset, the steel ball 26 will be forced to lock and snap into the groove of the connecting pipe 23 to lock, achieving the effect of quickly loading and unloading the fitting.

[0029] Working principle: When an electromagnetic heating type electrofusion fitting needs to be used, rotate the handle 15 to drive the connecting block three 13 connected to the connecting plate 14 to rotate. Then, the rotating shaft one 12 connected to the connecting block three 13 will drive the gear 10 to rotate. Subsequently, the gear 10 will drive the rack 9 to rotate. The connecting plate one 4 connected to the rack 9 will rotate on the connecting shaft one 3. The connecting block two 6 connected to the connecting plate one 4 will drive the connected telescopic rod 7 and the connecting block one 5 connected to the telescopic rod 7 and connected to the connecting shaft one 3 to rotate. Then, it will drive the clamping and fixing of the fitting to be combined. Subsequently, rotate the rotating disc 20 on the rotating shaft three 21 in the connecting shaft three 19 connected to the fitting one 8 to close the baffle 22 connected to the rotating shaft three 21 so that the liquid inside cannot enter. The fitting one 8 is provided with a fixing disc 18, and the fixing disc 18 can be combined and connected to the connecting shaft three 19 using bolts, thus realizing the combined splicing of the fittings. When the fitting needs to be loaded and unloaded, the outer shell one 25 can be pushed downward, causing the outer shell two 29 connected inside the outer shell one 25 to move downward together. When the outer shell two 29 moves downward, the locked steel balls 26 will be unlocked. At this time, the connecting pipe 23 connecting the fittings can be removed for replacement. After replacement, insert the connecting pipe 23 into the outer shell one 25. Then, release the downwardly pushed outer shell one 25, and the spring 28 on the connecting column one 27 will rebound to reset the connected outer shell one 25. When the outer shell one 25 is reset, the steel balls 26 will be locked and clamped into the card slots opened on the connecting column two 32, realizing the rapid loading and unloading of the fittings.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
