[0008] Furthermore, a hexagonal block is fixedly connected to the top of the connecting rod, a second connecting ring is provided in the connecting groove, a limit ring is fixedly connected to the outer wall of the second connecting ring, and two limit rods are fixedly connected to the outer wall of the limit ring, the two limit rods being adapted to the limit groove.

[0009] Furthermore, a spring is sleeved on the outer wall of the second connecting ring. The top of the spring is fixedly connected to the inner wall of the connecting groove, and the bottom of the spring is fixedly connected to the limiting ring. A tightening strip is fixedly connected to the end of the fixed ring, and the tightening strip extends into the fixed ring. Two fixing plates are fixedly connected to the outer wall of the fixed ring.

[0010] Furthermore, a rotating shaft is rotatably connected between the two fixed plates. The front side of the rotating shaft passes through the fixed plate located on the front side. A gear is fixedly connected to the outer wall of the rotating shaft. The gear meshes with the tightening strip. A fixed box is fixedly connected to the rear side of the fixed plate located on the front side. A limit block is slidably connected to the inner wall of the fixed box.

[0011] Furthermore, a second spring is provided inside the fixing box, the top of the second spring is fixedly connected to the fixing box, the bottom of the second spring is fixedly connected to the limiting block, and an adhesive plate is sleeved on the outer wall of the tightening strip.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a connecting mechanism, two aluminum-plastic composite pipes are inserted into connecting ring one, and then the connecting rod is inserted into the sliding groove. As the connecting rod is inserted, it will first contact connecting ring two. Then, the hexagonal block is rotated, and the connecting rod will rotate within connecting ring two. When the connecting rod rotates, a tightening effect is achieved. When connecting ring two tightens, spring one is compressed. As connecting ring two tightens, the limiting rod will match the limiting groove. Then, the hexagonal block will also contact connecting ring one. After tightening, under the action of spring one, the connecting rod and connecting ring two will have a pulling effect, thereby making the two aluminum-plastic composite pipes more tightly fixed through connecting ring one. This achieves the effect of connecting two aluminum-plastic composite pipes, effectively preventing problems such as loosening and leakage at the pipe connection, ensuring the sealing and stability of the connection. The operation is relatively simple, requiring no complicated tools or professional skills, improving installation efficiency, and saving installation time and costs.

[0014] 2. By setting up a repair mechanism, cracks inevitably occur during the use of aluminum-plastic composite pipes. In this case, a fixing ring and a tightening strip can be fitted onto the outer wall of the aluminum-plastic composite pipe. After fitting, the tightening strip is inserted into the fixing ring. Then, the rotating shaft on the fixing plate is rotated. As the shaft rotates, the tightening strip slides within the fixing ring. Simultaneously, as the tightening strip moves, the limiting block is pushed upwards by the tightening strip. Because the contact point between the limiting block and the tightening strip is arc-shaped, it is easily squeezed upwards. When the limiting block is pushed, the spring is compressed, thus cooperating with the limiting block through the tightening strip. Before the tightening strip tightens, the adhesive plate is positioned at the crack. As the adhesive plate tightens, it adheres to the crack, thereby achieving temporary repair of the aluminum-plastic composite pipe. Under the action of tightening force, it firmly adheres to the crack, effectively filling the crack, ensuring the sealing of the repaired pipe, reducing the risk of re-leakage, and ensuring the normal operation of the pipeline.

The bottom of the connecting rod 214 extends into the connecting groove 212, and a hexagonal block 215 is fixedly connected to the top of the connecting rod 214.

A first spring 219 is sleeved on the outer wall of the second connecting ring 216. The top of the first spring 219 is fixedly connected to the inner wall of the connecting groove 212, and the bottom of the first spring 219 is fixedly connected to the limiting ring 217. By setting the connecting mechanism 2, problems such as loosening and leakage at the pipe connection are effectively prevented, ensuring the sealing and stability of the connection. The operation is relatively simple, requiring no complicated tools or professional skills, which can improve installation efficiency and save installation time and costs.

[0026] Repair mechanism 3 includes a fixing ring 311 sleeved on the outer wall of aluminum-plastic composite pipe 1. A tightening strip 312 is fixedly connected to the end of the fixing ring 311, extending into the fixing ring 311. Two fixing plates 313 are fixedly connected to the outer wall of the fixing ring 311, and a rotating shaft 314 is rotatably connected between the two fixing plates 313. The front side of the rotating shaft 314 passes through the front fixing plate 313, and a gear 315 is fixedly connected to the outer wall of the rotating shaft 314. The gear 315 meshes with the tightening strip 312, and a gear 315 is fixedly connected to the rear side of the front fixing plate 313. A fixing box 316 is connected, and a limit block 317 is slidably connected to the inner wall of the fixing box 316. A second spring 318 is provided inside the fixing box 316. The top of the second spring 318 is fixedly connected to the fixing box 316, and the bottom of the second spring 318 is fixedly connected to the limit block 317.

[0027] A specific application of this embodiment is as follows: In use, first insert two aluminum-plastic composite tubes 1 into the connecting ring 101, and then insert the connecting rod 214 into the sliding groove 211. As the connecting rod 214 is inserted, it will first contact the connecting ring 216. Then, rotate the hexagonal block 215. At this time, the connecting rod 214 will rotate within the connecting ring 216. When the connecting rod 214 rotates, a tightening effect is achieved. When the connecting ring 216 tightens, the spring 219 will be compressed. As the connecting ring 216 tightens, the limiting rod 218 will match the limiting groove 213. Then, the hexagonal block 215 will also contact the connecting ring 101. After tightening, under the action of the spring 219, the connecting rod 214 and the connecting ring 216 will have a pulling effect, thereby making the two aluminum-plastic composite tubes 1 more tightly fixed by the connecting ring 101. Thus, the connection of the two aluminum-plastic composite tubes 1 can be achieved. In the course of use, the aluminum-plastic composite pipe 1 may inevitably crack. In this case, the fixing ring 311 and the tightening strip 312 can be fitted onto the outer wall of the aluminum-plastic composite pipe 1. After fitting, the tightening strip 312 is inserted into the fixing ring 311. Then, the rotating shaft 314 on the fixing plate 313 is rotated. As the rotating shaft 314 rotates, the tightening strip 312 will slide within the fixing ring 311. Simultaneously, as the tightening strip 312 moves, the limiting block 317 will be tightened. When the tensioning strip 312 is pushed upward, the contact area between the limiting block 317 and the tensioning strip 312 is arc-shaped, making it easier to be squeezed upward. When the limiting block 317 is pushed, the spring 318 will be compressed, and then cooperate with the limiting block 317 to pass through the tensioning strip 312. Before the tensioning strip 312 tightens, the adhesive plate 319 is located at the crack. As the adhesive plate 319 tightens, it will bond the crack, thereby achieving temporary repair of the aluminum-plastic composite pipe 1.
