Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection structures, in particular to a bellows sealing structure. Background Art

[0002] Hot water pipes in heating system products generally use silicone tubes, but the characteristics of silicone tubes will absorb odors, which will cause the water to become sour and have an odor, which will cause poor user experience. The existing solution is to coat the surface of the silicone secondary vulcanization, but this solution is complex and does not solve the fundamental problem of odor in hot water pipes. In addition, existing corrugated pipes usually only have smooth sections for connection at both ends, which makes it difficult to change the length of the corrugated pipe according to needs, which is easy to cause waste. Utility Model Content

[0003] The utility model discloses a bellows sealing structure which is easy to cut, aiming to improve the problem that the existing hot water pipeline adopts silicone tubes and is prone to produce odor and the problem that the bellows are difficult to apply with a fixed length.

[0004] The utility model adopts the following scheme:

[0005] The present application provides a bellows sealing structure that is easy to cut, comprising a tube body with a corrugated section and a smooth section, wherein connecting parts are respectively arranged at both ends of the tube body, wherein the smooth section is suitable for being cut to form another connecting part, wherein the connecting part is suitable for being inserted into a connecting piece, and a silicone seal is arranged between the smooth section and the connecting piece, wherein the silicone seal is configured to be able to be squeezed by the connecting piece so as to achieve sealing between the connecting piece and the connecting part.

[0006] Furthermore, a metal clamp is provided on the outer side of the connecting portion to strengthen the connection between the connecting piece and the pipe body.

[0007] Furthermore, the silicone seal is configured to be a hollow cylindrical shape so as to be sealed between the connecting portion and the connecting piece.

[0008] Furthermore, a smooth section is provided between two adjacent corrugated sections.

[0009] Furthermore, an annular groove is provided on the smooth section to facilitate cutting.

[0010] Beneficial effects:

[0011] This solution facilitates cutting by setting a smooth section, and after cutting, a tube body with two connecting parts can be formed for installing a silicone seal and a connecting part, so that both ends can be sealed and installed; the silicone seal is connected between the connecting part of the tube body and the connecting part to improve the sealing effect, and the silicone seal does not need to be passed through water during the whole process, which can solve the odor problem. The smooth section can be cut as needed to obtain the required length of the corrugated tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Combination Figures 1 to 3 As shown, this embodiment provides a bellows sealing structure that is easy to cut, including a tube body 1 with a corrugated section 11 and a smooth section 12, and connecting parts 13 are respectively provided at both ends of the tube body 1, and the smooth section 12 is suitable for cutting to form another connecting part 13, and the connecting part 13 is suitable for inserting a connecting piece 3, and a silicone seal 2 is provided between the smooth section and the connecting piece 3, and the silicone seal 2 is configured to be squeezed by the connecting piece 3 so as to achieve sealing between the connecting piece 3 and the connecting part 13.

[0017] Combination Figures 1 to 3 As shown, in this embodiment, the tube body 1 includes alternately arranged corrugated sections 11 and smooth sections 12, that is, a smooth section 12 is arranged between two adjacent corrugated sections 11. The corrugated sections 11 can facilitate bending of the tube body 1, and the smooth sections 12 can facilitate cutting to obtain the required length of the tube body 1 with the corrugated sections 11, so that cutting can be performed as needed, and due to the presence of the smooth sections 12, the cut tube body 1 includes two connecting portions 13 to achieve connection with the connecting piece 3 from both ends.

[0018] In this embodiment, the outer side of the connecting portion 13 can be set to be smooth, and the inner wall can also be set to be smooth. The smooth outer side is suitable for clamping by the metal clamp 4, and the smooth inner wall is suitable for connecting with the silicone seal 2, so that the tube body 1 and the connecting member 3 are sealed. Here, the metal clamp 4 is provided on the outer side of the connecting portion 13 to strengthen the connection between the connecting member 3 and the tube body 1 and prevent the connecting member 3 from falling off.

[0019] The silicone seal 2 is configured as a hollow cylinder to facilitate sealing connection between the connecting portion 13 and the connector 3. The cylindrical shape facilitates insertion of the connector 3 and forms a fully enclosed sealing structure on the outside of the connector 3.

[0020] In another embodiment, an annular groove 5 is provided on the smooth section 12 for easy cutting. Here, the annular groove 5 is provided on the surface of the smooth section 12 to play a guiding role. The annular groove 5 can be provided in the middle position of the smooth section 12.

[0021] This solution facilitates cutting by providing a smooth section 12, and after cutting, a tube body 1 with two connecting parts 13 can be formed for installing a silicone seal 2 and a connecting part 3, so that both ends can be sealed and installed; the silicone seal 2 is provided to connect between the connecting part 13 of the tube body 1 and the connecting part 3 to improve the sealing effect, and the silicone seal 2 does not need to be passed through water during the whole process, which can solve the odor problem. The smooth section 12 can be cut as needed to obtain the required length of the corrugated tube.
