Embodiment

[0024] according to the above Figure 1 to Figure 4 The illustrated embodiment installs the new pneumatic jack of the cost embodiment. The jack consists of an upper bag (9), a middle bag (10) and a lower bag (11) to form a rubber air bag part, and the air bag part is fixed on the base (7) for each air bag Air valve (4) is reserved on it. Two pneumatic shut-off valves (8) are respectively installed on the front end of the base (7), and the adjacent air bags are connected by the pneumatic shut-off valves (8) through the ventilation pipes (3). Pulley (12) is installed in base (7) left end. The lock nut (6) is located at the right end of the base (7) and is used to fix the ventilation pipe (3). Pull bar (1) is positioned at the right end of base (7), and pull bar (1) is fixed on the base (7) with bent steel plate (16) and bolt (5). The front end of the pull rod (1) is equipped with a baffle (14), the inflation valve (15) and the deflation valve (13) are located above the baffle...

Abstract

A new-style pneumatic jack consists of five parts, namely, an air bag, a draw bar, a base plate, a pulley and an air duct. The air bag part of the new-style pneumatic jack is divided into an upper bag, a middle bag and a lower bag in sequence from top to bottom, and the inner spaces of three air bag bulges are mutually independent. The side of each air bag is equipped with an air valve, and adjacent two air bag bulges are connected in series by a pneumatic stop valve used for the air duct. An upper air bag bulge is equipped with an anti-skidding rubber plate, so as to come into contact with the chassis of a car, and a lower air bag bulge is connected with the base plate. The air bag is equipped with a pneumatic valve device, and the device inflates quickly when the air bag enters the working state, and can be unloaded slowly during deflation. The new-style pneumatic jack is additionally equipped with a safety protection device on the basis of enhancing air bag strength, and overcomes the defect that the safety factor of a pneumatic jack in the prior art is low.

Description

technical field [0001] The technical scheme of the present invention relates to the automobile repair industry, specifically, the automobile is lifted to a certain height by a pneumatic device, so that the automobile repairman can work on the bottom of the automobile conveniently. Background technique [0002] At present, most of the jacks used in auto repair shops are mechanical, which is time-consuming, laborious and inconvenient to operate by manpower. There have been some pneumatic jacks on the market before, because this kind of jack has no safety protection measures during use, and the safety factor is not high. Once an air leak occurs during use, it poses a threat to the personal safety of the auto mechanic, so this kind of pneumatic jack has not been popularized before. The airbag of the novel pneumatic jack of the invention is made of four layers of cords and special rubber, which improves the strength of the airbag. The three air bag drums of the new pneumatic ja...
