Safety life saving apparatus with good window breaking effect

Abstract

The invention discloses a safety life saving apparatus with a good window breaking effect, which comprises a cylindrical life saving apparatus body, a cylindrical groove is formed in the center of oneside of the life saving apparatus body, a fixed box is fixedly connected to the inner groove wall of the cylindrical groove, and a piston plate is connected into the fixed box in a sealing and sliding manner; and a sliding rod is vertically fixed to the side, close to the opening of the cylindrical groove, of the piston plate, the end, away from the piston plate, of the sliding rod penetrates through the fixing box and is welded with a conical head, and a liquid storage cavity is formed in the middle of the life saving device body. The safety life saving apparatus has the advantages that: thepiezoelectric ceramic outputs direct current to the conductor ring, so that two contacts on the conductor ring respectively absorb heat and release heat, and the two heat conducting plates respectively heat and cool glass on two sides of the cylindrical groove by utilizing heat absorption of the first contact and heat release of the second contact, so that a temperature difference is formed between the glass window and the conductor ring; therefore, the glass can be crushed more easily, and the success rate of window breaking is further improved.

Description

technical field [0001] The invention relates to the technical field of lifesaving devices, in particular to a safety lifesaving device with good window breaking effect. Background technique [0002] With the rapid development of the economy, there are more and more small vehicles and private cars, modern transportation facilities have become very popular, the rapid development of automobiles and public transportation, natural disasters, emergencies, etc. safe question. For example, various accidents such as impact, rollover, fall, wading, and fire often cause the doors and windows to be locked, and the seat belts are locked, which seriously hinders the escape of drivers and passengers. The life-saving hammer is a kind of An important tool for assisting escape installed in closed cabins. [0003] The current life-saving hammer usually consists of a hammer head and a hammer handle. When in use, the operator needs to aim at a corner of the glass window, and it is necessary to...

Problems solved by technology

[0003] The current life-saving hammer usually consists of a hammer head and a hammer handle. When in use, the operator needs to aim at a corner of the glass window, and it is necessary to swing the safety hammer several times vigorously to break the glass window; The glass is broken, and swinging requires a large swinging space to store force. When the carriage deforms, the operator usually does not have enough space to swing the life-saving hammer, resulting in insufficient hitting force of the life-saving hammer, making it difficult to hit the glass. broken
