DETAILED DESCRIPTION

[0018] As Figures 1-2 The utility model relates to a kind of multi-layer water-blocking quick-assembly heating joint, including heating pipe and multi-layer joint, wherein: the heating pipe is divided into upper and lower two parts, the multi-layer joint 1 is connected with upper heating pipe 2, the multi-layer joint 1 is provided with quick plug interface for inserting heating pipe, the quick plug interface outer diameter gradually reduces in turn, and forms three layers of docking interface.

[0019] The outer diameter of the first layer docking interface 6 is slightly smaller than the inner diameter of the heating pipe, and an annular groove is provided on the first layer docking interface 6. A sealing rubber ring can be placed in the annular groove. The sealing rubber ring is inserted into the annular groove by heating and extrusion. The outer diameter of the sealing rubber ring is consistent with the inner diameter of the heating pipe.

[0020] The outer diameter of the second layer docking interface 7 is slightly smaller than the first layer docking interface 6, and the connection forms an annular platform I11. The sealing rubber ring I13 is sleeved outside the second layer docking interface 7 and reaches the annular platform I11 of the first and second layer docking interfaces. The outer diameter of the sealing rubber ring I13 is consistent with the inner diameter of the heating pipe and tightly contacts the heating pipe.

[0021] The outer diameter of the third layer docking interface 8 is slightly smaller than the second layer docking interface 7, and the connection forms an annular platform II12. The sealing rubber ring II14 is sleeved outside the third layer docking interface 8 and reaches the annular platform II12 of the second and third layer docking interfaces. The outer diameter of the sealing rubber ring II14 is consistent with the inner diameter of the heating pipe and tightly contacts the heating pipe.

[0022] In this application, the inner diameters of the interfaces of each layer are the same. The first layer docking interface 6 has two annular grooves, namely annular groove I9 and annular groove II10, which are arranged in parallel.

[0023] In this application, the sealing rubber rings on the second layer docking interface 7 and the third layer docking interface 8 are slightly wider than the sealing rubber ring in the annular groove of the first layer docking interface, but smaller than the width of the docking interface, leaving a gap.

[0024] In this application, two rivet fixing holes I3 are provided on the third layer docking interface 8 and are symmetrically distributed on both sides. The connection between the heating pipe and the third layer docking interface 8 is achieved by rivet connection.

[0025] In this application, the quick plug interface is used to connect the upper heating pipe 2 and the lower heating pipe 5. The quick plug interface includes the first layer docking interface 6, the second layer docking interface 7, and the third layer docking interface 8. The three-layer docking interface is inserted into the lower heating pipe 5 by pressing, and the connection between the upper and lower heating pipes is completed.

[0026] The first layer of the interface 6 is provided with two annular grooves, and sealing rubber rings are embedded in the two annular grooves; the first layer of the interface 6 and the second layer of the interface 7 have an annular platform I11; the second layer of the interface 7 is sleeved with a sealing rubber ring I, and the sealing rubber ring I is placed close to the annular platform I11; the second layer of the interface and the third layer of the interface have an annular platform II12; the third layer of the interface is sleeved with a sealing rubber ring II14, and the sealing rubber ring II14 is placed close to the annular platform II12; and a gap is left between the sealing rubber rings placed by the second layer of the interface and the third layer of the interface.

[0027] The working principle is as follows:

[0028] In use, the sealing rubber rings in the annular grooves I9 and the annular grooves II10 are tightly attached to the inner wall of the heating pipe through the expansion tension and friction force, thereby blocking the water overflow and achieving the sealing effect; the sealing rubber ring I13 and the sealing rubber ring II14 are also tightly attached to the inner wall of the heating pipe through the expansion tension and friction force, thereby achieving the sealing effect of the water pressure; when the water flow impacts the sealing rubber ring II14, an inward pressure is generated, and a difference is formed between the second layer of the interface and the third layer of the interface; since there is a gap between the sealing rubber ring I13 and the sealing rubber ring II14, the gap is filled with air, and after being compressed, the air generates a reverse force, which is offset by the water flow pressure, thereby forming a multi-layer water blocking structure.
