Safety can for preventing explosion of liquefied petroleum gas cylinder

Abstract

The invention relates to a safety can for preventing an explosion of a liquefied petroleum gas cylinder. The safety can comprises a can body and a can cover, wherein a supporting rod is fixedly arranged on the upper part of the outer side wall of the can body; a connecting rod is vertically rotatably arranged on the middle part of the can cover; the can cover can peripherally rotate around the connecting rod and at a top opening of the can body; the upper end of the connecting rod is bent toward the outer side of the can body and the connecting rod is hinged with the supporting rod through a hinge located at one end, away from the can body, of the supporting rod; an opening handle is fixedly arranged at the top of the can cover; a plurality of fixture blocks are fixedly arranged along the peripheral direction of the inner wall of the top opening of the can body; clamping slots corresponding to the fixture blocks are formed in the peripheral side wall of a plug part of the can cover, respectively; gaps are formed between the adjacent clamping slots and in the peripheral side wall of the plug part of the can cover; after the gaps are rotated along with the can cover till the corresponding fixture blocks are located in the corresponding gaps, the fixture blocks are separated from the plug part of the can cover through the gaps; an airtight handle extending toward the outer side of the can body is arranged at the top of the can cover. The safety can has beneficial effects of simple structure, convenience in operation, quick opening and closing and excellent pressure-bearing and airtight property.

Description

technical field [0001] The invention relates to an explosion-proof device for a liquefied petroleum gas cylinder, in particular to an explosion-proof safety tank for a liquefied petroleum gas cylinder. Background technique [0002] Existing liquefied petroleum gas cylinders leak liquefied petroleum gas due to improper operation or quality problems of the cylinder itself during use, resulting in waste of liquefied petroleum gas, and even ignited by external igniting factors to explode, causing casualties and property losses. To avoid such accidents, designers usually focus on improving the operation optimization of the steel cylinder itself and the improvement of the manufacturing process, ignoring the external protection measures. Even if there are external protection measures, the effect is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safety tank with simple structure, convenient operation, fast o...
