Abstract

The invention provides a powerful vehicle-mounted safety hammer which comprises a handle, an inner shell, an impact spring, a firing pin and an outer shell, wherein the handle is fixed at the back side of the inner shell; one end of the impact spring is connected with the handle, and the other end of the impact spring is connected with the firing pin; the inner shell is slidably installed in the outer shell; the back side of the outer shell is provided with a limit device used for preventing the inner shell from sliding out of the outer shell; the firing pin comprises a head part and a limit part connected with the head part; the limit part is provided with a pin; the limit part of the firing pin and the impact spring are contained in the inner shell; the front end of the firing pin is provided with a groove by which the head part can pass through the inner shell; the outer shell is provided with a guide groove and a positioning groove communicated with the guide groove; the pin is located in the guide groove or the positioning groove; and the front end of the outer shell is provided with a through hole through which the head part can penetrate. In the use process of the safety hammer, the spring is just compressed through the handle, and energy is stored by the spring; when the energy is accumulated to a certain degree, the energy can be automatically released so as to smoothly complete a crushing action; and the powerful vehicle-mounted safety does not need large waving space any more, is easy to operate and is not limited by knocking position.

Description

technical field [0001] The invention relates to a vehicle-mounted safety hammer used in buses and small cars. Background technique [0002] China is a country with a large population in the world, and the number of cars owned also ranks first in the world. However, the incidence of traffic accidents is much higher than that of developed countries such as the United States. In recent years, the frequent traffic accidents of public transport, school buses, and small cars have given us a deep reflection on the safety of cars. There is a simple safety hammer in the car in the past, but can this safety hammer play a real role in traffic accidents? Some recent traffic accidents give us the answer is no. In the past, the safety hammer consisted of a hammer head and a hammer handle. When using it, it was necessary to swing the safety hammer to break the glass. This kind of safety hammer has many disadvantages: [0003] 1. Swinging the safety hammer requires enough space, and it i...

Problems solved by technology

[0003] 1. Swinging the safety hammer requires enough space, and it is difficult to play a role in a narrow space;

[0004] 2. There must be a certain amount of explosive force at the moment of knocking. It is difficult to break the tempered glass with a small force. Female passengers or students in the school bus may not have enough force;
