Hand-operated expansion type rescue device

Abstract

The invention provides a hand-operated expansion type rescue device. The hand-operated expansion type rescue device is characterized in that supporting cantilevers 7 are propped open or folded by using a connecting tray 5 and a connecting rods 6 according to the principles of worm transmission and screw transmission. The hand-operated expansion type rescue device is used for providing a safe living space for trapped persons in earthquakes or in other collapse accidents. Further, the hand-operated expansion type rescue device is combined with other rescue equipment so as to rescue the trapped persons. The hand-operated expansion type rescue device mainly comprises a worm 1, a worm wheel 2, a nut 3, a lead screw 4, the connecting tray 5, the connecting rods 6 and the supporting cantilevers 7.

Description

Technical field: [0001] The invention relates to a manual expansion rescue device Background technique: [0002] There is no such manual expansion type rescuer both at home and abroad. Invention content: [0003] The utility model relates to a manual expansion rescue device, which utilizes the principle of worm drive and screw drive to expand and retract the supporting arm beam through a connecting plate and a connecting rod. [0004] The technical solution adopted by the present invention to solve its technical problems is: 1, the design of connecting plate, support arm beam, worm screw, turbine, leading screw, 2, the installation and debugging of whole equipment. [0005] Specific implementation: This manual expansion rescue device is composed of a worm 1, a turbine 2, a nut 3, a lead screw 4, a connection plate 5, a connecting rod 6, and a support arm beam 7. Turn the worm by hand, and the worm drives the worm wheel and then drives the lead screw Rotate, through the c...
