[0033] The connecting mechanism 500 in the embodiment is a structure for connecting and positioning adjacent two water pipelines 1.

[0034] As Figure 1 , Figure 2 , Figure 3 indicated, connecting mechanism 500 includes connecting ring 501 fixed to the outer side of end plate 2 and capable of extending to the outer side of tail plate 3 on the left end of adjacent water pipeline 1, locking pin 502 penetrating the outer side of connecting ring 501 and having a number of at least three, knocking block 503 fixed to the end of locking pin 502 away from water pipeline 1, first extrusion protrusion 504 fixed to the left side of locking pin 502, two second extrusion protrusions 505 fixed to the outer side of locking pin 502, locking grooves 506 opened on the outer side of tail plate 3, screw bodies 507 penetrating between the outer side of tail plate 3 and the right side of corresponding end plate 2, nuts 508 threadedly connected to the outer side of screw bodies 507; The outer side of tail plate 3 is provided with a positioning assembly capable of positioning sliding with the corresponding connecting ring 501.

[0036] It should be noted that the right side of the positioning sliding groove 602 is provided in an open manner, and the two positioning blocks 601 are symmetrically distributed upward and downward, so that the two positioning blocks 601 can be respectively slid from the outside to the inner side of the corresponding positioning sliding groove 602, thereby facilitating the positioning of the positions of the end plate 2 and the tail plate 3. The right side of the end plate 2 and the left side of the tail plate 3 are both bonded with sealing rings 7, the inner diameter of the sealing ring 7 is equal to the inner diameter of the water conservancy pipeline 1, and the right end of the extension pipe 4 penetrates the inner side of the corresponding two sealing rings 7 and is inserted into the left side of the adjacent water conservancy pipeline 1, so that the sealing ring 7 can seal the connection between the two adjacent water conservancy pipelines 1, and the extension pipe 4 can normally extend into the adjacent water conservancy pipeline 1, thereby achieving the effect of water delivery and reducing the water delivery burden of the connection, thereby being able to be used for a longer time.

[0037] In addition, as shown in Figure 4 and Figure 5 , the outer side of the connecting ring 501 is provided with a plurality of insertion grooves for inserting a plurality of knocking blocks 503, so that the knocking block 503 can enter the inner side of the corresponding insertion groove, so that the outer side of the connecting ring 501 looks relatively flat, maintaining the aesthetics of the connection.

[0040] It should be noted that in the above embodiment, if subsequent disassembly work is considered, a rectangular plate can be fixed on the top of the knocking block 503, and the right side of the rectangular plate extends to the right side of the connecting ring 501. After removing the screw rod body 507 and the nut 508, the rectangular plate is knocked by a hammer to drive the knocking block 503 to move upward, thereby loosening the locking pin 502, so that it can be removed. The distance between the end of the locking pin 502 close to the water pipeline 1 and the side of the locking groove 506 close to the water pipeline 1 is one centimeter, which can be knocked downward after a certain wear after the first extrusion protrusion 504 is removed several times, so as to achieve the positioning effect.
