Abstract
The utility model relates to a jack in the field of the mechanical repairing tool, and in particular to an inflatable jack, which adopts the technical proposal that an air bag and a hoisting block are arranged inside a cavity of a U-shaped shell from up to down, and an air charging opening and an air discharging opening of the air bag are arranged at the outer side of the U-shaped shell. A retaining valve is arranged between the air charging opening and the air discharging opening, and the upper surface of the hoisting block is provided with a carrying plate. The inflatable jack is free from the oil leakage phenomenon which leads to the unable application; moreover, the stressed area is large, when requiring the large-area hoisting, the operation is very convenient, and the production cost is low.
Description
Technical field
The utility model relates to a kind of jack in mechanical maintenance tool in use field, specifically is a kind of inflatable jack.
Background technology
Existing jack mainly is made up of lifting mechanism and hydraulic supply unit that hydraulic actuating cylinder and piston constitute, and its shortcoming is that oil leakage phenomenon often takes place, and can't use, and field of load is little, when needs during than the large tracts of land lifting, and inconvenient operation.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, but a kind of large tracts of land lifting and easy to operate inflatable jack are provided.
Technical scheme is: set gradually air bag and lifting piece from top to bottom in the chamber of " U " shape shell, the inflation inlet and the exhausr port of the arranged outside air bag of " U " shape shell.
Between inflation inlet and exhausr port, check valve is set, above the lifting piece support board is set.
Oil leakage phenomenon can not take place in the utility model, thereby causes the common fault that can't use, and area of thrust surface are big, and when the lifting of needs large tracts of land, operation is very easy, and cost of manufacture is low.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment.
The specific embodiment
As shown in the figure, in the chamber of " U " shape shell 1, set gradually air bag 4 and lifting piece 2 from top to bottom, the inflation inlet 6 and the exhausr port 7 of the arranged outside air bag 4 of " U " shape shell 1.At inflation inlet 6 and 7 of exhausr ports check valve 5 is set, support board 3 is set above the lifting piece 2.
During use, close blow off valve 7, inflation inlet 6 connects source of the gas, and gas progresses in the air bag 4, and air bag 4 expands and promotes lifting piece 2 upward movements, and the object on the support board 3 will be picked up; After hours, open blow off valve 7, press loading surface 3 downwards, the gas in the air bag 4 can be discharged through blow off valve 7.
Claims (2)
1, a kind of inflatable jack is characterized in that: set gradually air bag and lifting piece from top to bottom in the chamber of " U " shape shell, the inflation inlet and the exhausr port of the arranged outside air bag of " U " shape shell.
2, inflatable jack according to claim 1 is characterized in that: between inflation inlet and exhausr port check valve is set, above the lifting piece support board is set.
