Abstract
The utility model is composed of a cylindrical form cylinder body, a piston, an adjusting screw rod, an air inlet cone valve, an air outlet cone valve, etc., can be used for the lifting of various light-duty and medium automobiles and other equipment when installed and repaired. Compared with the existing hydraulic jack, the utility model can be inversely arranged and the stress angle can be freely rotated, can be remotely operated which can eliminate the safe threat to the operator in the process of lifting, having the advantages of long lifting travel, no oil pollution, simple structure, and low cost.
Description
The utility model relates to a kind of instrument that carries out lifting when can be used for various light-duty, the compact cars of installation, maintenance and other equipment.
The lifting gear that is widely used in installation, maintenance automobile and other equipment now is a hydraulic jack, but there are following six problems in it: can not be inverted and any rotation loading angle, the lifting stroke is short, can not remote servicing, operating personal there is security threat, easy oil leakage and polluting, structure and manufacturing process be complexity, and use cost is higher.
The air pressure jack that the objective of the invention is to overcome the above-mentioned shortcoming of prior art and provide a kind of and high pressure manual pump (the high pressure manual pump is another utility application that the applicant and the application propose simultaneously) to be used.
The purpose of this utility model reaches by following approach: in a columniform cylinder body, a piston is arranged, middle of piston has an adjusting screw(rod), the top of adjusting screw(rod) connects with direct jack-up and the top of putting down workpiece, in the bottom of cylinder body is cylinder inner cavity, join with air inlet cone valve and exhaust poppet valve, the other end of air inlet cone valve and its middle part link for the outer connecting bolt of circular hole, outer connecting bolt connects with the delivery piping of high pressure manual pump or other compressors again, and the other end of exhaust poppet valve then connects with discharge orifice.When high pressure draft entered cylinder inner cavity by the air inlet cone valve, the equipment of piston and need jack-up was by jack-up.
The utility model has the following advantages compared to existing technology:
1, can be inverted or rotate loading angle arbitrarily.
2, the lifting stroke is longer, can reach with the 3-4 of the hydraulic jack of hoisting capacity doubly.
3, can remote servicing, eliminate in the lifting process security threat to operating personal.
4, can not pollute because of leakage of oil.
5, structure and manufacturing process are simpler.
6, use cost is lower.
Description of drawings: accompanying drawing is an elevation cross-sectional view of the present utility model.
The utility model describes in detail below with reference to the embodiment in the accompanying drawing: as shown in drawings, piston (4) is arranged in cylinder block (3), there is adjusting screw(rod) (7) at the middle part of piston (4), the top of adjusting screw(rod) (7) and direct jack-up and put down workpiece the top connect, in the bottom of cylinder body (3) is cylinder inner cavity (A), join with air inlet cone valve (2) and exhaust poppet valve (5), the other end of air inlet cone valve (2) and its middle part join for the outer connecting bolt (1) of circular hole, outer connecting bolt (1) connects with the delivery piping of high pressure manual pump or other compressors again, the other end of blow off valve (5) connects with exhausr port (6), when high pressure manual pump or other compressor operating, high pressure draft endoporus of connecting bolt (1) outside the delivery duct warp is pushed air inlet cone valve (2) open and is entered cylinder inner cavity (A), under the effect of pressure current, piston (4) upward movement, play live load, after starting is finished, regulate exhaust poppet valve (5), pressure current in the cylinder is drained through discharge orifice (6), put down load, end starts to work.
Claims (1)
