Problems solved by technology

The deficiency of this existing structure is just to be: 1. safety hammer is generally placed on the window corrugated when unused state, is easy to just can be taken off, and this just provides convenience to the not high people of individual quality, The safety hammer is easily lost, which eventually affects the normal use of the escape
According to the survey, most of the safety hammers equipped on buses and other places have disappeared, causing great safety hazards
2. The energy used by the existing safety hammer mainly comes from the human arm, and its destructive power to closed objects such as windows is limited
3. Finally, the existing safety hammer cannot be easily found by the user in a closed environment with poor light at night, which affects the success rate of escape

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the fixed safety hammer of the present invention includes a hammer head 4, the hammer head 4 is connected to the top of an elastic connecting rod 3, and the bottom of the elastic connecting rod 3 is sleeved in a fixed base 1 through a rotating shaft 2 and can be fixed The base 1 rotates inside. In this embodiment, the fixed base 1 is fixed at the installation point through a connecting piece, and hangs vertically in an unused state, such as being fixed on the window edge between two glass windows by screws to prevent it from being moved or taken away. . The fixed base 1 can be made of ordinary gray cast iron (HT150). The material of the hammer head 4 can be 45# steel, which is prepared through quenching and tempering treatment and surface quenchi...

Description

technical field [0001] The invention mainly relates to the field of escape equipment, in particular to a safety hammer suitable for closed occasions such as glass windows. Background technique [0002] The known "safety hammer" is mainly used in enclosed places such as public buses, long-distance buses, and trains, and refers to a tool for escaping by breaking glass, cutting safety belts, etc. in the event of an accident. The traditional safety hammer structure is mainly composed of two parts: a metal hammer head and a plastic hammer handle. The deficiency of this existing structure just is: 1. safety hammer is generally placed on the window corrugated when unused state, is easy to just can be taken off, and this just provides convenience to the not high people of individual quality, Cause the safety hammer to be very easy to lose, and finally affect the normal use when escaping. According to investigations, most of the safety hammers that are equipped on occasions such as...
