Embodiment Construction

[0011] exist figure 1 In the shown embodiment, it is the pneumatic control circuit diagram of the whole system. When the smoke sensor 4 detects the smoke concentration, the circuit is opened, the relay circuit of the solenoid valve 5 is connected, the compressed air provided by the air compressor 6 pushes the piston cylinder, and the air is quickly discharged into the atmosphere through the quick exhaust valve 1, realizing the cylinder The rapid movement of 2 drives the hammer head 3 to smash the window glass.

[0012] exist figure 2 In the shown embodiment, it is the assembly diagram of the safety hammer. The hammer head 1 is a cone, and the section A-A is a circular surface. The cylinder 1 is fixed on the fixing plate 10 through the bolt 8, and the fixing plate 10 fixes the whole device on the On the suitable position of automobile, according to the difference of automobile interior space position, the shape of fixing plate 10 can be changed.

Abstract

The invention relates to a vehicle-mounted safety hammer mainly for assisting passengers to escape under the conditions that a bus breaks out a fire and falls into water. The vehicle-mounted safety hammer is characterized in that power is provided by an air compressor; a manual switch and a smoke sensor control an electromagnetic directional valve; and the head part of a cylinder piston rod is welded with a hammer head subjected to heat treatment. The vehicle-mounted safety hammer of the invention has low cost, small size, easy installation, repeated use, manual and automatic integration, easy control and convenient operation and realizes the purpose of assisting the passengers to fast escape in a sudden disaster.

Description

technical field [0001] The invention relates to a vehicle-mounted safety protection device integrating fire alarm and manual / automatic glass breaking. It belongs to the technical field of safe escape. Background technique [0002] At present, domestic urban and rural areas are developing rapidly, road traffic is becoming more and more perfect, and buses are gradually increasing and becoming larger. But at the same time, it also brings many problems. One of them is the safety protection of the bus. Falling into water and catching fire happen from time to time. Although there are safety hammers inside the bus, in the face of sudden disasters, people often just instinctively squeeze towards the door, even if someone notices the safety hammer. , but it may not be able to get and break the window glass. There is still a major problem in the existing vehicle-mounted safety hammer: theft! [0003] The development purpose of the present invention is mainly to provide an alarm at...
