Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a vapour-pressure type jack, including dolly body 1, dolly body 1 includes dolly chassis 2 and

dolly handle

3, 2 upper end fixed mounting on dolly chassis has

gasbag

4, 2 lower extreme fixed mounting on dolly chassis have unable adjustment base 5, fixed surface installs reinforced connection piece 6 on unable adjustment base 5, reinforced

connection piece

6 and 3 fixed connection of dolly handle, fixed surface installs handle body 7 on 3 tops of dolly handle, fixed surface installs on 3 tops of dolly handle has gas charging switch 8 and gas outlet switch 9, gas charging switch 8 outside movable mounting has gas charging valve 10, gas outlet switch 9 outside movable mounting has gas outlet valve 11.

Further, the trolley handle 3 is designed to be a hollow cuboid structure, the miniature inflator pump 12 is fixedly mounted inside the trolley handle 3, the air pipe 13 is fixedly mounted at one end of the miniature inflator pump 12, the air pipe 13 is fixedly connected with the bottom of the air bag 4, the other end of the miniature inflator pump 12 is fixedly connected with the inflation switch 8 and the air outlet switch 9, and the miniature inflator pump 12 can inflate the air bag 4 to enable the air bag 4 to deform and bulge.

Further, top end fixed mounting has a top dish 14 on the gasbag 4, and top dish 14 is cylindrical structural design, and the 14 centre of a circle of top dish overlaps with 4 centre of a circle positions of gasbag, and reinforcement connection piece 6 installs a pair ofly about 3 perpendicular central lines symmetric distributions of dolly handle, and top dish 14 can avoid gasbag 4 and by a top article direct contact, makes things convenient for work to develop better.
