[0005] In order to solve the above technical problems, the utility model adopts the technical scheme of a waterproof ring for pipeline clamping pressure connection, which comprises a ring body, the ring body comprises an upper ring layer and a lower ring layer, and is set as a double-layer coaxial waterproof ring, and the whole is in the form of a hollow cylindrical structure, the diameter of the upper ring layer is slightly smaller than the diameter of the lower ring layer, and the bottom end of the upper ring layer and the top end of the lower ring layer are fixedly connected with each other, a placement ring is tightly clamped on the top end of the upper ring layer, and a slot is formed on the top side of the lower ring layer for inserting the first pipeline.

[0006] As a further improvement of the utility model, the slot is set as an annular groove matched with the outer edge of the first pipeline.

[0007] As a further improvement of the utility model, the lower ring layer is provided with an annular chamber, and a support ring is arranged in the annular chamber.

[0008] As a further improvement of the utility model, the support ring is made of stainless steel, and the diameter is smaller than the second pipeline.

[0009] As a further improvement of the utility model, a groove is formed on the edge side of the top layer of the upper ring layer, and a convex ring matched with the groove is fixedly arranged at the bottom end of the placement ring.

[0010] As a further improvement of the utility model, the outer wall of the insertion ring is a smooth plane.

[0011] The utility model discloses the beneficial effect has: the utility model discloses a double -layer coaxial waterproof ring is seted up to waterproof ring, and the top side of lower ring layer is provided with the slot, and the first pipeline is inserted into the slot, to guarantee the preliminary connection of first pipeline and waterproof ring, then, the second pipeline is set up in the lower ring layer outside, guaranteeing that first pipeline and waterproof ring go in second pipeline inside, then using the compaction tool makes first pipeline, second pipeline and each other compaction, because setting up annular chamber and support ring, can avoid the compaction process, waterproof ring excessive compression or uneven stress, prevent liquid leakage.

[0017] In the present specification, the orientation terms such as up, down, left, right, front, back, top, bottom, etc. mentioned or possibly mentioned are defined relative to its structure, and they are relative concepts. Therefore, it is possible to change accordingly according to its different positions, different use states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0018] In the present specification, the singular forms "a", "said" and "the" are intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein means and includes any or all possible combinations of one or more associated listed items.

[0019] In order to make the technical problems, technical schemes and beneficial effects to be solved in the present application more clear and explicit, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present application and not used to limit the present application.

[0020] The utility model provides a waterproof ring for pipeline clamping pressure connection, including ring body 1, in addition select first pipeline and second pipeline carry out clamping pressure operation, and first pipeline diameter is slightly smaller than second pipeline,

[0021] As shown in the accompanying Figures 1-3 The ring body 1 includes an upper ring layer 101 and a lower ring layer 102, and is set as a double-layer coaxial waterproof ring, and the whole is in a hollow cylindrical structure. The diameter of the upper ring layer 101 is slightly smaller than that of the lower ring layer 102, and the bottom end of the upper ring layer 101 is fixedly connected with the top end of the lower ring layer 102. The top end of the upper ring layer 101 is tightly clamped with an insertion ring 2. The insertion ring 2 facilitates the insertion of the upper ring layer 101 into the first pipeline. A groove is formed in the edge of the top layer of the upper ring layer 101. The bottom end of the insertion ring 2 is fixedly provided with a protruding ring matched with the groove. The reliable connection of the upper ring layer 101 and the insertion ring 2 is ensured. The outer wall of the insertion ring 2 is provided as a smooth plane, and the outer wall is designed with polishing.

[0022] As shown in the accompanying Figures 1-4 The top side of the lower ring layer 102 is provided with a slot 3 for inserting the first pipeline. The slot 3 is set as an annular groove matched with the outer edge of the first pipeline. The annular groove is tightly matched and clamped with the outer wall edge of the first pipeline. The lower ring layer 102 is provided with an annular chamber 4, and the annular chamber 4 is provided with a support ring 5. The support ring 5 is made of stainless steel and has a diameter smaller than that of the second pipeline. The support ring 5 is used to provide support for the lower ring layer 102 to avoid excessive compaction or deformation of the ring body 1 during clamping and compaction.

[0023] Working principle: in the specific implementation of the utility model, the first pipeline and the second pipeline are selected for clamping pressure operation, and the diameter of the first pipeline is slightly smaller than that of the second pipeline. The upper ring layer 101 is guided downward along the insertion ring 2 at the top end and inserted into the pipe body of the first pipeline. Then, the edge of the first pipeline is inserted into the slot 3 to ensure that the lower ring layer 102 is tightly clamped with the first pipeline. Then, the lower ring layer 102 is aligned with the second pipeline until the first pipeline and the ring body 1 are completely placed inside the second pipeline. Then, the clamping force is adjusted by using the clamping forceps to align the connection position of the support ring 5 and perform clamping operation. The first pipeline and the second pipeline are tightly clamped with each other. At the same time, the support provided by the support ring 5 can effectively remind the operator of the operation force to avoid damage to the ring body 1 due to excessive clamping force and affect the sealing performance.
