[0024] Specifically, the control box 3 is mainly used to control the telescopic movement of the telescopic rod 6, the positioning plate 4 is used to connect the plurality of connecting blocks 5, the connecting blocks 5 are used to fix the plurality of telescopic rods 6, the mounting rod 17 is used to connect the detector 18, the electric push rod 20 is used to control the movement of the trapezoidal block 22, the wedge blocks 23 on the front and rear sides of the trapezoidal block 22 slide in the wedge groove 24 opened in the movable block 25, because the wedge block 23 and the wedge groove 24 are both wedge-shaped, so when the wedge block 23 slides in the wedge groove 24, the movable block 25 can generate a corresponding movement, and by sliding The block 26 slides inside the mounting frame 27 and the limit block 21 can limit the movable block 25, so that the movable block 25 can only move horizontally.

[0025] Reference Figure 1 and Figure 3The disassembly assembly includes a connecting rod 7, which is slidably connected to the inside of the telescopic rod 6. A cross plate 9 is fixedly connected to the front side of the connecting rod 7. The left and right sides of the cross plate 9 are rotatably connected to a rotating rod 10. The ends of the two rotating rods 10 away from the cross plate 9 are rotatably connected to a transmission block 11. The front sides of the two transmission blocks 11 are fixedly connected to a clamping block 12. The front side of the cross plate 9 is fixedly connected to a compression spring 14. The inside of the cross plate 9 is slidably connected to a slide rod 15, and the compression spring 14 is sleeved on the outer periphery of the slide rod 15. The left and right sides of the inside of the telescopic rod 6 are fixedly connected to a support rod 13. The two clamping blocks 12 are respectively slidably connected to the outer peripheries of the two support rods 13. One end of the slide rod 15 away from the cross plate 9 is fixedly connected to a limiting plate 16. A card slot is provided inside the mounting rod 17. The two card blocks 12 are respectively slidably connected to the inside of the two card slots. The end of the connecting rod 7 away from the cross plate 9 is fixedly connected to a push plate 8.
[0026] Specifically, the connecting rod 7 is used to control the movement of the cross plate 9, and the rotating rods 10 on the left and right sides of the cross plate 9 are used to generate a pulling force or a thrust when rotating to control the transmission block 11 to drive the card block 12 to move. The two ends of the rotating rod 10 are respectively connected to the cross plate 9 and the card block 12. The length of the rotating rod 10 cannot be changed, so when the cross plate 9 applies a thrust or a pulling force to the rotating rod 10, the rotating rod 10 will rotate. The transmission block 11 is connected to the card block 12 to transmit motion. When the transmission block 11 is affected by the rotation of the rotating rod 10 and moves, it will drive the card block 12 to move. The mounting rod 17 A card slot is provided inside, and the card block 12 can slide into the card slot. The card block 12 cooperates with the card slot to make the disassembly and installation of the mounting rod 17 more convenient. The detector 18 is used to facilitate the movement of the mounting rod 17. The support rod 13 is used to support the movement of the card block 12. When the card block 12 moves, it will move along the outer periphery of the support rod 13. The compression spring 14 is used to reset the movement to generate thrust to push the cross plate 9 to move. The slide bar 15 is used to protect the compression spring 14 from excessive distortion during the squeezing process. The limit plate 16 is used to cooperate with the cross plate 9 to squeeze the compression spring 14.
[0027] Working principle: when it is necessary to detect air leakage on the plastic bottle, the plastic bottle is moved between the two clamping plates 29 by the conveyor belt, and the position of the plastic bottle is detected by the positioning block 2. After the position of the plastic bottle is determined, the electric push rod 20 is started, and the trapezoidal block 22 is moved downward by the electric push rod 20. When the trapezoidal block 22 moves downward, the wedge blocks 23 on its front and rear sides will slide in the wedge groove 24 opened by the movable block 25. When the wedge block 23 slides out of the wedge groove 24, a pulling force is applied to the movable block 25, so that the two movable blocks 25 move toward each other. When the movable block 25 moves, the slider 26 moves in the mounting frame 27, so that the movable block 25 can only move horizontally. When the movable block 25 moves, the circular block 28 on the top of the movable block 25 will drive the clamping plate 29 to move together, so that the two clamping plates 29 move toward each other to fix the plastic bottle. Then, the telescopic rod 6 is controlled to telescopically move by the control box 3, so that the detector 18 is in close contact with the plastic bottle, and then the inflation in the plastic bottle is tested for air leakage.
[0028] Secondly, when the specifications of the plastic bottles are different and the corresponding detector 18 needs to be replaced, the connecting rod 7 is moved by pressing the push plate 8, and the cross plate 9 is moved along the slide rod 15 through the connecting rod 7 to squeeze the compression spring 14. When the cross plate 9 moves, a thrust is applied to the rotating rod 10. When the two rotating rods 10 are subjected to the thrust, they will rotate in the opposite direction. When they rotate in the opposite direction, a thrust is applied to the transmission block 11, and the transmission block 11 drives the card block 12 to move, so that the card block 12 moves along the support rod 13. When the card block 12 exits the card of the mounting rod 17, the card block 12 is moved. When the two locking blocks 12 are in the groove, the mounting rod 17 can be separated from the telescopic rod 6. During installation, it is only necessary to embed the mounting rod 17 into the telescopic rod 6 to ensure that the card block 12 can slide into the card groove of the mounting rod 17. Then, the push plate 8 can be released, and the compression spring 14 loses the extrusion force of the cross plate 9, thereby generating a reset movement. When the compression spring 14 resets and moves, it pushes the cross plate 9 to move, so that the two rotating rods 10 rotate relative to each other, so that the two card blocks 12 slide into the card groove inside the mounting rod 17, and the mounting rod 17 and the telescopic rod 6 are assembled. The operation is simple, fast and convenient.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
