[0002] Embedded parts are a common way of connecting pipes in construction or civil engineering. By embedding prefabricated pipe connectors into concrete structures, pipe connection and maintenance can be easily performed. Embedded parts are usually used for fixed installation of pipes on floors and walls.

[0003] The Chinese utility model patent with application number 201220272596.7 discloses an anti-seepage embedded part for drainage pipes. The embedded part is a tubular body with a plurality of water stop rings on its outer wall. The water stop ring can be closely combined with the floor slab during concrete pouring, so the anti-leakage effect is significant, and adverse social impact caused by floor slab leakage around the pipe can be avoided. However, the existing embedded parts are connected to the pipe by inserting the pipe and then filling it with concrete for fixing. After installation in this way, the pipe and the embedded part are not tightly connected, and water seepage is prone to occur. In addition, the work is cumbersome and the installation efficiency is low. Therefore, it is necessary to design an embedded part for HDPE riser passing through the floor slab to solve the above problems. Utility Model Content

[0006] Preferably, a wiring barrel is fixed on the cylinder, and the wiring post is arranged in the wiring barrel.

[0007] Preferably, a placement groove is provided in the cylinder, the heating component is arranged in the placement groove, and the inner wall of the cylinder is provided with a convex layer located at the placement groove.

[0008] Preferably, the heating component comprises a resistance wire.

[0009] Preferably, a friction layer is provided on the inner wall of the cylinder.

[0010] Preferably, the diameter of the connecting ring located in the middle of the cylinder is larger than the diameter of the connecting rings located in the upper and lower parts of the cylinder.

[0011] Preferably, a clamping sleeve cooperating with the wiring barrel is fixed on the end cover, and a ring cooperating with the cylinder is fixed on the end cover.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model forms a structure that is convenient for electric fusion connection with a pipeline through the mutual cooperation of a terminal post, a heating component and a cylinder, which can make the electric fusion connection with the pipeline tighter, more convenient and faster, and improve work efficiency. The mutual cooperation of the end cover and the cylinder facilitates shielding of the cylinder to prevent dust or concrete from entering the interior of the cylinder during normal placement and installation, and to avoid wiping again during subsequent electric fusion to affect work efficiency.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The following is combined with Figure 1-4 The specific implementation modes of the present utility model are further described in detail.

[0021] In this embodiment, by Figure 1-3As shown, the utility model includes a cylinder 1, on which a plurality of connecting rings 2 are arranged, at least one positioning ring 3 is fixed at the bottom of the cylinder 1, and each positioning ring 3 is provided with a positioning hole 4, and a terminal post 5 is arranged on the cylinder 1, and the terminal post 5 is electrically connected to a heating component 7 fixed in the cylinder 1, and an end cover 6 is fixed on the top of the cylinder 1. A pipe is inserted into the cylinder 1, and an electric fusion device is connected to the terminal post 5, and then the heating component 7 is driven by the terminal post 5 to melt the inner wall of the cylinder 1 and the pipe is connected by electric fusion, which can improve the installation speed.

[0022] In this embodiment, by Figure 2-3 As shown, a wiring barrel 8 is fixed on the cylinder 1 , and the terminal 5 is fixed in the wiring barrel 8 .

[0023] In this embodiment, by Figure 2 and Figure 4 As shown, a placement groove 9 is opened in the cylinder 1, and the heating component 7 is fixed in the placement groove 9. A convex layer 15 covering the placement groove 9 is fixed on the inner wall of the cylinder 1. The heating component 7 is located in the placement groove 9 and directly performs electric melting on the convex layer 15 of the inner wall of the cylinder 1, so that the cylinder 1 and the pipeline can be completely fused into one, eliminating the risk of water leakage. The convex layer 15 can improve the tightness with the pipeline, and when the convex layer 15 is melted, it can be more tightly connected with the pipeline.

[0024] In this embodiment, by Figure 2 and Figure 4 As shown, the heating component 7 includes a resistance wire.

[0025] In this embodiment, by Figure 2 and Figure 4 As shown, a friction layer 10 is provided on the inner wall of the cylinder 1 , and the friction layer 10 is fixed on the cylinder 1 . The friction layer 10 can make the pipeline fit tightly against the inner wall of the cylinder 1 .

[0026] In this embodiment, by Figure 1-2 As shown, the diameter of the connecting ring 2 located in the middle of the cylinder 1 is larger than the diameter of the connecting rings 2 located in the upper and lower parts of the cylinder 1. After multiple connecting rings 2 are covered with concrete, they will be compacted by the concrete. When the cylinder 1 is pulled upward, the connecting rings 2 are pressed by the concrete, which will increase the resistance to pulling upward and prevent the cylinder 1 from being easily pulled out.

[0027] In this embodiment, by Figure 2-3As shown, a cartridge 11 cooperating with the wiring barrel 8 is fixed on the end cover 6, and the cartridge 11 can be inserted into the wiring barrel 8 to block the wiring barrel 8 to prevent dust or concrete from entering the wiring barrel 8. A ring 12 cooperating with the cylinder 1 is fixed on the end cover 6. The cartridge 11, the end cover 6 and the ring 12 can cover the wiring barrel 8 and the cylinder 1 to prevent dust or concrete from entering the cylinder 1 when the cylinder 1 is cast or stored again, resulting in the need to clean the cylinder 1 when it is used, affecting work efficiency and being cumbersome.

[0028] When the utility model is used, during the construction of drainage pipes through cast-in-place concrete floor slabs, before pouring concrete, the cylinder 1 is first fixed on the floor slab, and the cylinder 1 and the floor slab can be fastened together by passing an iron nail through the positioning hole 4 on the positioning ring 3, and then concrete is poured to embed the cylinder 1 in the concrete floor slab. When the concrete solidifies and the pipe needs to be installed, the end cover 6 is removed, and then the pipe is inserted, and the terminal 5 is connected by the electric melting device, so that the heating component 7 heats and melts the convex layer 15 to be connected with the pipe by electric melting;

[0029] Similarly, when the embedded parts are used for fixing and installing pipes on the wall, they can be used according to the above steps.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
