Problems solved by technology
[0002] At present, when the liquefied natural gas cylinders for automobiles are pressurized and inflated, they are inflated by directly connecting the air supply pipe to the mouth of the gas cylinder. This method has the disadvantage of poor airtightness and easy leakage. If there is no natural gas phenomenon, the gas cylinder will be unqualified, which will not only cause the loss of natural gas, but also pose a major safety hazard

The invention discloses an air leakage prevention pressing device which mainly comprises a rear cover, a front cover and a sealing ring, and is characterized in that the rear cover consists of a left rear cover and a right rear cover; the left rear cover and the right rear cover are arranged in a bilateral symmetry manner; bolts with nuts are respectively mounted in middle grooves of the right rear cover and the left rear cover and grooves in two ends of the right rear cover through rotating shafts; the right rear cover and the left rear cover are fixed together by clamping the bolts at the two ends of the right rear cover into the grooves of the left rear cover; the bolts in the middle parts of right rear cover and the left rear cover are clamped into grooves in the front cover; the sealing ring is arranged in an annular groove between the front cover and the rear cover. Due to the arrangement, an air conveying pipe is more tightly connected with an air bottle opening, so that the sealing property of the air conveying pipe and the air bottle opening is improved, and air leakage can be effectively prevented; furthermore, the air leakage prevention pressing device is simple in structure and convenient to mount and dismount and can be operated by one user, so that the labor is reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to a pressing device, in particular to a pressing device for preventing gas leakage when a liquefied natural gas cylinder for automobiles is pressed and inflated. Background technique [0002] At present, when the liquefied natural gas cylinders for automobiles are pressurized and inflated, they are inflated by directly connecting the air supply pipe to the mouth of the gas cylinder. This method has the disadvantage of poor airtightness and easy leakage. If there is no natural gas phenomenon, then this gas cylinder is just unqualified, which will not only cause the loss of natural gas, but also have great potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a pressing device for preventing gas leakage when the liquefied natural gas bottle for automobile is pressed and inflated. [0004] In order to achieve the above object, the present invention mainly consists of a rear...
