In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] Example 1:

[0034] This embodiment provides a connection mechanism for a conveying pipeline, including a first pipe body 1 and a second pipe body 2, and further comprising:

[0035] The connecting assembly includes a fixed base 3, a positioning base 4, and a locking base 5. The fixed base 3 is provided with a first mounting groove 31 and a second mounting groove 32. The positioning base 4 is installed in the first mounting groove 31. The end of the first tube 1 is located in the positioning base 4. The locking base 5 is installed on the outside of the fixed base 3 and one end of the locking base 5 abuts against the end of the first tube 1.

[0036] The snap ring 6 is radially scalable and can be mounted between the positioning seat 4 and the first mounting groove 31;

[0037] The pusher sleeve 7 is axially movable and installed in the second mounting groove 32 to push the snap ring 6 to unfold radially.

[0038] The first tube 1 is provided with a slot 11, and a sealing ring is provided inside the slot 11. The second tube 2 is provided with a plug part 21, and the plug part 21 and the slot 11 are plugged in and engaged.

[0039] In this technical solution, an external thread structure is provided on the outer wall of the fixed seat 3, and a matching internal thread structure is provided on the inner side of the locking seat 5. The first mounting groove 31 and the second mounting groove 32 in the fixed seat 3 are arranged in a stepped shape. When installing this connecting mechanism, the pusher sleeve 7 is first installed in the second mounting groove 32, then the snap ring 6 is installed in the first mounting groove 31, then the positioning seat 4 is placed in the first mounting groove 31, so that the snap ring 6 is placed between the positioning seat 4 and the first mounting groove 31. Then, one end of the first tube body 1 is placed on the positioning seat 4. Finally, the locking seat 5 is threadedly connected to the fixed seat 3. At the same time, the locking seat 5 and the positioning seat 4 clamp the end of the first tube body 1, and the snap ring 6 is also pressed into the first mounting groove 31 by the positioning seat 4.

[0040] Specifically, the card-connecting ring 6, such as Figure 3 As shown, it includes a fixing plate 61, which is arranged in a ring structure; a plurality of elastic snap-fit ​​plates 62, which are all installed at an incline on the inner side of the fixing plate 61; wherein, a plurality of slots are provided on the outer wall of the second tube body 2, and the plurality of elastic snap-fit ​​plates 62 are snapped into the slots one by one.

[0041] When a connection is required between the first tube 1 and the second tube 2, the connecting assembly and the first tube 1 are first assembled together. Then, the insertion part 21 of the second tube 2 is inserted into the slot 11 of the first tube 1. The fixing plate 61 and the elastic snap-fit ​​piece can be made of a metal material with a certain degree of elasticity. During the insertion process, the insertion part 21 will contact the elastic snap-fit ​​plate 62, causing the elastic snap-fit ​​piece to deform and its end to shift radially outward. When the slot on the second tube 2 moves to the designated position, the insertion part 21 presses the sealing ring in the slot 11 to form a sealed connection. The elastic snap-fit ​​piece is no longer compressed and returns to its original shape. The end of the elastic snap-fit ​​piece moves into the slot and engages with it, thereby restricting the axial movement of the first tube 1 and completing the fixed connection between the first tube 1 and the second tube 2.

[0042] When the first tube 1 and the second tube 2 need to be disassembled, first loosen the locking seat 5 and the fixing seat 3 so that the locking seat 5 is no longer in contact with the first tube 1. Then, hold the fixing seat 3 and move the insertion part 21 of the second tube 2 further closer to the slot 11 of the first tube 1 to push the first tube 1 to move. At this time, the end of the elastic snap plate 62 will move axially in the slot. Then push the push sleeve 7 so that the push sleeve 7 abuts against the end of the elastic snap plate 62 to push the elastic snap plate 62 out of the slot. In this way, the insertion part 21 of the second tube 2 can be pulled out from the slot 11 of the first tube 1, realizing the disassembly and separation of the first tube 1 and the second tube 2.

[0043] In summary, this structural design enables rapid assembly and disassembly between two conveying pipes, and its operation is simple and convenient for workers, thereby effectively improving the assembly efficiency of conveying pipes.

[0044] Example 2:

[0045] This embodiment provides a connection mechanism for a conveying pipeline, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0046] Furthermore, several flexible snap-fit ​​plates 62 are arranged in a ring array.

[0047] This structural design allows each elastic snap-fit ​​plate 62 to be evenly distributed on the fixed plate 61, ensuring uniform stress distribution on the periphery of the second tube body 2, thereby effectively improving the connection strength between the second tube body 2 and the snap-fit ​​ring 6.

[0048] Example 3:

[0049] This embodiment provides a connection mechanism for a conveying pipeline, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] Furthermore, the pusher sleeve 7 includes:

[0051] The main body 71 is movably disposed between the second tube 2 and the fixed base 3 along the axial direction;

[0052] The tapered portion 72 is mounted at the end of the main body portion 71 and is located in the second mounting groove 32.

[0053] In this technical solution, the pusher sleeve 7 consists of a main body 71 and a tapered part 72. The structure of the tapered part 72 is designed to match the inclination angle of the elastic locking plate 62. When the tapered part 72 contacts the elastic locking plate 62, the outer side of the tapered part 72 fits against the inner side of the elastic locking plate 62. Then, as the pusher sleeve 7 moves, it pushes the elastic locking plates 62, causing them to gradually open radially. This structural design ensures that the deformation point of the locking ring 6 is located at the connection between the elastic locking plate 62 and the fixing plate 61, effectively preventing the elastic locking plate 62 from bending and deforming, thus demonstrating high practicality.

[0054] Example 4:

[0055] This embodiment provides a connection mechanism for a conveying pipeline, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] Furthermore, it also includes a seal 8, which comprises:

[0057] The first sealing part 81 has a "V" shaped groove 83.

[0058] The second sealing part 82 is integrally connected to the first sealing part 81;

[0059] The first tube body 1 has a protrusion 12 and a protrusion 13 at its end. The positioning seat 4 has a third mounting groove 41 and an arc groove 42. The first sealing part 81 is located in the third mounting groove 41. The protrusion 13 and the groove 83 are fitted together. The second sealing part 82 is located in the arc groove 42 and abuts against the protrusion 12.

[0060] In this technical solution, the protrusion 12 on the end of the second tube 2 abuts against the locking seat 5. The protrusion 12 has an arc surface that matches the arc groove 42 on the positioning seat 4. The first sealing part 81 is installed in the third mounting groove 41 of the positioning seat 4, and the second sealing part 82 is located within the arc groove 42. When the first tube 1 and the second tube 2 are connected, the first sealing part 81 and the second sealing part 82 are located between the positioning seat 4 and the protrusion 12, ensuring a tight seal between the first tube 1 and the positioning seat 4. The protrusion 13 on the first tube 1 inserts into the "V"-shaped groove 83 of the first sealing part 81, causing the first sealing part 81 to open radially, ensuring that the inner side of the first sealing part 81 is tightly fitted against the outer wall of the second tube 2. This enhances the sealing performance between the second tube 2 and the first tube 1. Furthermore, in conjunction with the use of a sealing ring, a double sealing effect is achieved, effectively preventing leakage and improving safety.

[0061] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
