A kind of vehicle window glass crushing negative pressure positioning magnetic acceleration hammer

Abstract

The invention discloses a vehicle window glass crushing negative-pressure positioning magnetic acceleration hammer. The hammer comprises a protective outer cylinder, a pressing handle is fixedly connected to one side, away from the protective outer cylinder, of a semispherical rubber ring, a magnet is fixedly connected to the middle of the left side of the pressing handle, the side, away from thepressing handle, of the magnet is fixedly connected with a hammer rod, the side, close to the magnet, of the outer surface of the hammer rod is sleeved with a protective gasket, an electromagnetic induction mechanism is movably connected to the middle position of the outer surface of the hammer rod, a magnetic field supply mechanism is arranged on the side, away from the protective gasket, of theelectromagnetic induction mechanism on the outer surface of the hammer rod, a falling-off mechanism is fixedly connected to the left side of an inner cavity of the protective outer cylinder, and a negative pressure adsorption mechanism is arranged on the side, away from the magnetic field supply mechanism, of the falling-off mechanism. The invention relates to the technical field of escape hammers. Acceleration is carried out through the principle of opposite attraction of magnetic force, the device is suitable for most people, air pressure does not exist in the device, external energy supplyis not needed, surrounding safety can be protected, and the using effect is stable.

Description

technical field [0001] The invention relates to the technical field of escape hammers, in particular to a window glass crushing negative pressure positioning magnetic acceleration hammer. Background technique [0002] The glass windows on the bus are fixed in an airtight manner, and the glass is usually toughened glass. The escape hammer is a hammer that is installed on densely populated public transportation such as buses and subways, and is used to break glass in a crisis situation. When a dangerous situation occurs in the car and the glass window needs to be opened to escape, the escape hammer equipped in the car is used to knock the window glass, so that the glass is broken to form a window hole to escape from the window hole. [0003] According to Chinese patent CN109999378A, when the pressure sensor sends a signal to the controller, the controller controls the battery to energize the energized coil, and the energized coil can generate electromagnetic force when the en...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a window glass shattering negative pressure positioning magnetic acceleration hammer, which can solve the problem that the existing window escape hammer requires a large force to be used, which is not conducive to the use of people with small strength. It needs to consume energy and is greatly affected by the outside world, which is likely to endanger the safety of the surrounding area and affect the quality of its own use
