Description

A push-type fast escape safety belt buckle

technical field

The invention relates to the automobile industry, in particular to a push-type fast escape safety belt buckle.

Background technique

The seat belt is an important part of the car and an important facility to ensure the safety of the driver. It is also called the "life belt". Seat belts, as the basic protective device to protect drivers and passengers during car collisions, were born earlier than cars. As early as 1885, seat belts appeared and were used on carriages to prevent passengers from falling from the carriage. Over time, various countries have successively stipulated that car occupants must wear seat belts. The Ministry of Public Security of China issued a notice on November 15, 1992, stipulating that from July 1, 1993, all passenger cars (including cars, jeeps, Vans, mini-cars) Drivers and front seat passengers must use seat belts. Article 51 of the Road Traffic Safety Law stipulates: When a motor vehicle is running, the driver and passengers shall use seat belts in accordance with regulations. Drivers and passengers should wear safety helmets as required. Since the seat belt came out, there have been 10 million kilometers of seat belts, installed in more than 1 billion cars around the world, and its length is enough to circle the earth's equator 250 times, or go to and from the moon 13 times. "It has become the primary consideration of drivers and passengers, and it has also become one of the most important performances of cars and so on.

When using the seat belt, slowly pull the seat belt out of the hidden box, and insert the lock into the safety buckle seat. Once the emergency brake or crash occurs, the speed and force of the seat belt will increase due to inertia. The belt will be blocked by the mechanism in the hidden box so that the belt will not be pulled out quickly, thereby ensuring the safety of the driver. But in daily use, although the driver inserts the lock in the buckle seat, the lock buckle is not locked sometimes, and once an accident happens, the lock head will fall off from the buckle seat, and the safety of the driver cannot be guaranteed; The seat belt buckles on the car are all plastic structures. Although they are light in weight, they are prone to aging over time. Once an accident occurs, the force on the seat belt will increase greatly, and the buckle may be broken and damaged. The driver is thrown out due to inertia. In addition, because the buckle seat is generally arranged at the lower part of one side of the seat, when driving at night, it is necessary to fumble in the dark, and it is inconvenient to lock and unlock. If the phenomenon cannot be solved, the seat belt at this time will not only fail to play a safe role, but will become an obstacle for the driver to escape.
