Embodiment Construction

[0008] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0009] like figure 1 As shown, a safety hammer for buses comprises a sleeve 6, a push rod 2 is arranged in the sleeve 6, and one end of the push rod 2 protrudes from the sleeve 6, and a handle 3 is provided at the protruding end, and the push rod The other end of 2 is a spiked part 5, and a stopper 1 is provided on the push rod 2 near the spiked part 5, and a spring is set between one end of the sleeve 6 and the stopper 1 on the pusher 2 4. The other end of the sleeve 6 is provided with a suction cup 7 .

[0010] Under normal circumstances, the suction cup 7 is adsorbed on the knocking point on the glass, and the rest is folded from the tail of the suction cup 7 and hung in the car. Under the action of the spring 4, the spiked part 5 hits the knocking point with greater force, and then pulls the sleeve 6 to tear the damaged glass apart.

Abstract

A safety hammer for a bus comprises a sleeve. A push rod is arranged in the sleeve; one end of the push rod extends out of the sleeve, and a handle is arranged at the extended end; the other end of the push rod is a piercing part; a stop block is arranged at a position, close to the piercing part, of the push rod; a spring is arranged between the end, positioned at the sleeve, of the push rod and the stop block; and a suction disc is arranged at the other end of the sleeve. By using the safety hammer for the bus, the hitting point of glass can be hit accurately with slight effort.

Description

technical field [0001] The invention belongs to the field of mechanical devices, in particular to a safety hammer for buses. Background technique [0002] In order to avoid casualties caused by emergencies on the bus and quickly evacuate the crowd, the current buses are equipped with safety hammers to break the glass in an emergency and escape from the windows. However, from the perspective of daily safety, the automobile glass used in the current bus is relatively strong. In order to prevent the escape hammer from being broken, a fixed tapping point is set on the glass, and tapping this position can get twice the result with half the effort. Effect. But in many cases, it is impossible to accurately locate in an emergency. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a safety hammer for buses, which can accurately strike the striking point on the glass without...
