Leakage prevention type sucker hook

[0018] in figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 The syringe 2 has a barrel-shaped structure, the hook 5 is connected to the lower end of the syringe 2, an upper socket 6 is provided on the outer wall of the upper end of the syringe 2, and a lower socket 6 is provided on the outer wall of the lower end of the syringe 2, Both sockets 6 are provided with through holes communicating with the syringe 2. The piston 11 is arranged in the injection cylinder 2, and a plurality of sealing rings 12 are arranged on the piston 11, and the lower end of the driving rod 1 extends into the injection cylinder 2 and is connected with the upper end of the piston 11. The suction cup 3 is a disc-shaped structure. The suction cup 3 is made of elastic material. The supporting ring 4 is connected to the top of the dome on the outer side of the suction cup 3. The inner side of the suction cup 3 is provided with an annular shape along the edge of the port of the suction cup 3 The leak-proof groove 8 is a grooved structure. The upper plug 7 is connected to the upper end position of the outer surface of the suction cup 3, and the lower plug 7 is connected to the lower end position of the outer surface of the suction cup 3. Both the upper and lower plugs 7 are provided with via holes 9 communicating with the leak-proof groove 8. The syringe 2 is connected to the suction cup 3 through the support ring 4, the upper and lower plugs 7 on the suction cup 3 are respectively connected with the upper and lower sockets 6 on the syringe 2, and the through holes 9 in the upper and lower plugs 7 are connected with the through holes in the upper and lower sockets 6 respectively. The plugging agent 10 is arranged in the injection barrel 2, and the plugging agent 10 is a water-soluble colloidal liquid.

[0019] in figure 1 , Figure 4 , Figure 5 , Figure 7 , Picture 8 During installation, the suction cup 3 is pressed by the syringe 2 and the suction cup 3 is adsorbed on the wall. When the leak-proof groove 8 on the suction cup 3 and the wall together form an annular channel, the syringe 2, the lower through hole 9, The leak-proof groove 8, the upper via 9 and the injection barrel 2 can be connected in sequence. The piston 11 is pushed by the driving rod 1, and the piston 11 can inject the plugging agent 10 in the syringe 2 through the lower via 9 into the channel formed by the leak-proof groove 8 and the wall surface, thereby preventing the suction cup 3 from leaking, and excess The plugging agent 10 will enter the syringe 2 through the upper via 9. When disassembling, spray the suction cup 3 with water. When the plugging agent 10 in the leak-proof groove 8 melts, the suction cup 3 can be removed.
