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.
