Technical Field

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

[0002] HVAC is an integral part of a building, encompassing heating, ventilation, and air conditioning. Pipes are a crucial component of the HVAC industry. When connecting two pipes, flanges are often used. However, when flanges are used, if the pipe diameter changes, flanges of different diameters must be used to install the pipes. This prevents the installation of different pipes and affects the applicability of the connection mechanism. Utility Model Content

[0003] The purpose of the utility model is to solve the defect in the prior art that different pipelines cannot be installed, which affects the applicability of the connecting mechanism, and to propose a pipeline connecting mechanism.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A pipeline connection mechanism is designed, including a connecting sleeve, both ends of the connecting sleeve are fixedly connected to tapered tubes, sealing rings are provided on the inner walls of the two tapered tubes, the connecting sleeve is rotatably connected to two threaded sleeves through bearings, both ends of the two threaded sleeves are threadedly connected to threaded rods, the four threaded rods are limited by a limiting mechanism, the four threaded rods are connected to two pipelines through an abutment mechanism, the two pipelines are respectively located in the two tapered tubes, and the threads at both ends of the two threaded sleeves are in opposite directions.

[0006] Preferably, the limiting mechanism includes a limiting groove, the limiting groove is provided on the connecting sleeve, a limiting block is fixedly connected to the threaded rod, and the limiting block is slidably disposed in the limiting groove.

[0007] Preferably, the abutment mechanism includes a connecting ear, the connecting ear is fixedly connected to the threaded rod, a bolt is threadedly connected to the connecting ear, and a fixing block is fixedly connected to the pipe.

[0008] Preferably, an abutment column is rotatably connected to the bolt via a bearing, and the abutment column can abut against the fixing block.

[0009] Preferably, the sealing ring is HNBR hydrogenated nitrile rubber.

[0010] Preferably, a support ring is fixedly connected between the tapered tube and the connecting sleeve.

[0011] The utility model proposes a pipe connection mechanism with the following beneficial effects: when the pipe diameter changes, the abutment mechanism abuts the pipe, and rotating the threaded sleeve will drive the threaded rod to rotate, thereby adjusting the position of the threaded rod in the threaded sleeve, so as to drive the two pipes to abut the sealing rings, thereby achieving a sealing connection, so as to connect pipes of different diameters, thereby increasing the applicability of the connection mechanism.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Example 1: Reference Figure 1-3 , a pipe connection mechanism includes a connecting sleeve 1, both ends of the connecting sleeve 1 are fixedly connected to a tapered tube 11, and sealing rings are provided on the inner walls of the two tapered tubes 11. The sealing rings are also a tapered structure. The connecting sleeve 1 is rotatably connected to two threaded sleeves 2 through a bearing. Both ends of the two threaded sleeves 2 are threadedly connected to threaded rods 3. The four threaded rods 3 are limited by a limiting mechanism. The four threaded rods 3 are connected to two pipes 7 through an abutment mechanism. The two pipes 7 are respectively located in the two tapered tubes 11. The thread directions at both ends of the two threaded sleeves 2 are opposite. When the diameter of the pipe 7 changes, the abutment mechanism abuts the pipe 7, and rotating the threaded sleeve 2 will drive the threaded rod 3 to rotate, thereby adjusting the position of the threaded rod 3 in the threaded sleeve 2, so as to drive the two pipes 7 to abut the sealing rings, thereby playing a role of sealing connection, so as to connect pipes of different diameters, thereby increasing the applicability of the connecting mechanism.

[0018] The abutment mechanism includes a connecting ear 8, which is fixedly connected to the threaded rod 3. A bolt 5 is threadedly connected to the connecting ear 8. A fixed block 4 is fixedly connected to the pipe 7. An abutment column 10 is rotatably connected to the bolt 5 through a bearing. The abutment column 10 can abut against the fixed block 4. If the bolt 5 is abutted against the fixed block 4, the friction force when the bolt 5 is rotated is increased, and the difficulty of rotating the bolt 5 is increased. By rotating the bolt 5, the abutment column 10 is Figure 1 In the position shown, when the threaded rod 3 is rotated and tightened, the fixing block 4 is driven to move, so that the pipe 7 abuts and fixes the sealing ring.

[0019] The limiting mechanism includes a limiting groove 14, which is opened on the connecting sleeve 1. A limiting block 13 is fixedly connected to the threaded rod 3. The limiting block 13 can be slidably set in the limiting groove 14. The threaded rod 3 is limited by the limiting block 13 and the limiting groove 14, thereby preventing the threaded rod 3 from rotating.

[0020] Example 2: Reference Figure 1-3 As another preferred embodiment of the present invention, based on Example 1, the sealing ring is HNBR hydrogenated nitrile rubber, which has tear resistance and compression deformation resistance properties, preventing damage to the pipe 7 when it abuts against the sealing ring.

[0021] Example 3: Reference Figure 1-3 As another preferred embodiment of the present invention, on the basis of embodiment 1, a support ring 12 is fixedly connected between the tapered tube 11 and the connecting sleeve 1. The support ring 12 plays a supporting and fixing role, which is beneficial to the direct connection effect between the tapered tube 11 and the connecting sleeve 1.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
