Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety hammers, in particular to a safety hammer for buses with hand protection. Background Art
[0002] A bus safety hammer usually refers to a safety tool used for breaking windows and rescuing in emergency situations. In public transportation, if an accident occurs and the vehicle's doors and windows cannot be opened normally, passengers may need to use a safety hammer to break the windows to escape.
[0003] However, the handle of a traditional bus safety hammer does not have protective properties. When a user holds the bus safety hammer and hits the car window glass, the broken glass can easily scratch the user's hand, increasing the risk of escaping by breaking the window. At the same time, when the alloy hammer head breaks the car window, if too much force is used, the alloy hammer head will be subjected to the reaction force of the car window glass, which can easily cause hand concussion. If insufficient force is used, the broken surface of the car window glass by the alloy hammer head is small, and the car window glass needs to be hammered multiple times, which increases the time it takes to break the window glass and escape by using the bus safety hammer.

The reinforcing ribs integrally formed on the outer surface of the protective rubber sleeve reinforce the protective rubber sleeve and reduce the deformation of the protective rubber sleeve when it is hit by an external impact. The alloy hammer head is movably installed inside the hammer head cover through a reset mechanism, so that when the alloy hammer head hits the glass, the alloy hammer head can achieve the purpose of hammering the glass multiple times through the reset mechanism, thereby solving the problem of poor breaking effect of a single glass hammering. At the same time, the reset mechanism also weakens the force of the glass on the alloy hammer head The reaction force transmitted to the hand, the pliers head arranged at one end of the hammer handle away from the hammer head cover, and the blade fixed in the pliers head by bolts, make it easy for the blade to cut the glass that is adhered after breaking, so as to expand the broken surface of the car window glass.
[0013] 2. A reset mechanism consisting of a support plate, a buffer spring, a limit ring, a first magnet ring and a second magnet ring is used, and the support plate is fixed in the hammer head sleeve. At the same time, the buffer springs are symmetrically fixed on both sides of the support plate, so that the support plate can buffer the alloy hammer head through the buffer spring. At the same time, the end of the alloy hammer head is fixed with a first magnet ring, and the surface of the support plate is fixed with a second magnet ring. At the same time, the opposite magnetic poles of the first magnet ring and the second magnet ring are the same, so that the alloy hammer head is reset after being squeezed under the action of the buffer spring, the first magnet ring and the second magnet ring. When the alloy hammer head hammers the glass, the alloy hammer head hammers the glass multiple times through the reset mechanism, thereby achieving the characteristic of expanding the glass breaking surface.
