Abstract

The invention relates to a leakage prevention type sucker hook. An upper socket and a lower socket are arranged at the upper end and the lower end of a syringe respectively, and through holes communicated with the syringe are formed in the two sockets. A piston is arranged in the syringe, and the lower end of a driving rod stretches into the syringe and is connected with the upper end of the piston. An annular leakage prevention groove is formed in the part, along the edge of a sucker port, on the inner side face of a sucker, an upper plug and a lower plug are arranged at the upper end and the lower end of the outer side face of the sucker respectively, and via holes communicated with the leakage prevention groove are formed in the upper plug and the lower plug. The upper socket and the lower socket on the syringe are connected and conducted with the upper plug and the lower plug on the sucker respectively. A hook body is connected to the lower end of the syringe, and a leakage blocking agent is arranged in the syringe. When the sucker sucks a wall, an annular channel can be formed by the leakage prevention groove in the sucker and the wall together. When the driving rod pushes the piston to inject the leakage blocking agent in the syringe into the annular channel through the lower via hole, the sucker port can be sealed with the leakage blocking agent, and thus air leakage of the sucker can be prevented.

Example Embodiment

[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.
