Embodiment

[0008] Example: figure 1 As shown, this embodiment includes a stud 1 with external threads, which is characterized in that a blind hole is provided on the screw head, and a detonator 2, a retainer 3, and a fixed cover 6 are arranged in the blind hole in turn, and the electrode head 4 of the detonator 2 passes through Electric wire 7 is connected with detonation switch.

[0009] The current connected to the external wire 7 enters the detonator 2 through the detonator electrode head 4, thereby detonating it. After the explosion, the screw body part where the detonator 2 is located is broken, so that the outer window frame is separated from the compartment body. The retaining ring 3 has the functions of shockproof, moisture-proof, heat insulation and sealing, and prevents the detonator from being detonated by bad external factors. The detonation voltage of the detonator is DC 1.2V.

Abstract

The invention relates to a self-destruction screw, which comprises a stud bolt with external threads. The self-destruction screw is characterized in that a blind hole is formed on a screw head; a detonator, a retainer and a fixing cover are sequentially arranged in the blind hole; and the electrode end of the detonator is connected with a detonating switch through an electric wire. The self-destruction screw has the advantages of simple structure and low manufacturing cost. Vehicle windows fixed by the self-destruction screw can drop in time during emergency, so that the time for passengers to escape is saved.

Description

Technical field: [0001] The invention specifically relates to a self-explosive screw. Background technique: [0002] With the continuous improvement of people's requirements for the comfort of vehicles, air-conditioned trains and automobiles have become very common. The air-conditioned compartment is relatively airtight, with poor air circulation, and the windows are all sealed and fixed tempered glass. In the event of a fire, passengers escape by opening the inner doors on both sides of the compartment or smashing the glass with a safety hammer. Usually there are a lot of passengers in the compartment. When a fire broke out, the passengers would be crowded and trampled due to panic, so they could not escape in time. The safety hammer is an easy to lose item. On June 5, 2009, a bus burning in Chengdu caused a fire. 25 people died and 76 people were injured, which caused a sensation in the whole country. One of the reasons for the accident was that the safety hammer equipp...
