A high-efficiency safety hammer

Abstract

The invention discloses an efficient safety hammer which is mounted a mounting position of the inner wall of a traffic tool. The safety hammer comprises a hammer head and a hammer handle connected with the hammer head, wherein the hammer head is of a housing structure, and is internally equipped with an impact mechanism and a spring, and is used for supplying stroke for the impact mechanism to move; the spring sleeves between the impact mechanism and the housing; and when the impact mechanism moves, the spring provides opposite acting force to the impact mechanism. According to the efficient safety hammer disclosed by the invention, the structure of the safety hammer is redesigned, and palm strike type detonation is utilized to provide certain stroke, a plurality of fixed points of a fixed rail can be knocked to instantly focus beating force for intensively striking a vehicle window. The palm strike type mode is used for performing multiple-fixed-point breaking on the vehicle window, so that the efficient safety hammer is more accurate and efficient in comparison with a conventional safety hammer. The design increases window breaking speed to increase escape probability of passengers, focuses life safety of people better, and has an extremely high social value.

Description

technical field [0001] The invention relates to a public safety device, in particular to a high-efficiency safety hammer. Background technique [0002] At present, the car window blasting device is mainly installed near the car window in the form of a percussion type blasting hammer. This kind of percussion hammer is sometimes difficult to break when used by people with small arms. There have been palm-slap blasting hammers and directional automatic blasting devices in China. These blasting devices are easy to be stolen, and the use efficiency of blasting hammers is not high. The cost of automatic directional blasting devices is high, and it is not easy to cover all car windows. . Chinese patent CN101565029A discloses a pre-assembled automobile glass safety hammer, which belongs to the palm-type blasting hammer. The elastic bowl of this blasting hammer is pre-installed on the glass. The tip of the metal hammer faces the glass. Hit the cover. This kind of safety hammer, be...

Problems solved by technology

This kind of safety hammer, because the tip of the metal hammer is closer to the glass, requires a greater force to break the glass, and it is fixed on a fixed point on the glass, so the efficiency of breaking windows is particularly low. In times of crisis, it is difficult to achieve the rescue effect against time
