Problems solved by technology

[0003] The matching accessories for seat belts are buckles. The existing seat belt buckles are mostly plastic products. In addition to the advantages of non-conductivity, shock resistance and non-corrosion, low thermal conductivity, and high strength-to-weight ratio, some common defects are prone to occur. , such as buckle assembly is not in place or falls off empty; snap assembly is difficult to achieve complete sealing, and it is easy to produce permanent deformation due to creep after assembly, and the ability to adapt to the environment is poor; the buckle design and molding conditions The requirements are relatively strict, and it is easy to produce defective products or even waste products

Abstract

The invention relates to the technical field of processing and manufacturing auto parts, and discloses a durable creep-resistant plastic buckle for automobile seat belts. The plastic buckle is prepared by adding basalt fiber to the raw materials, and is made of the following components in terms of mass percentage: Polybutylene terephthalate accounts for 40-45%, polycarbonate accounts for 20-25%, polyamide fiber accounts for 5-7%, basalt fiber accounts for 4-6%, and the rest is filled masterbatch. The present invention changes It solves the problems that the current plastic snaps made of pure polymers are brittle, have poor tensile strength, are prone to permanent deformation due to creep, and have poor environmental adaptability. At the same time, they also have excellent moisture resistance and acid resistance. Alkali corrosion prolongs the service life of the plastic buckle and improves personal safety.

Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing of auto parts, and in particular relates to a durable plastic buckle for anti-creep automobile seat belts. Background technique [0002] As early as more than 100 years ago, there were seat belts on carriage seats in European and American countries to prevent passengers from being knocked off the carriage. On May 20, 1902, a car race was held in New York, USA. Engineer Walter Baker, a contestant, was afraid of overturning and being injured in a fierce car race. He was inspired by the case of a toddler being tied up in a stroller to prevent him from falling out of the car, and he also nailed it on the "Torpedo" racing car. A few ropes to tie yourself and your fellow motor mechanic tight when racing. During the race, the high-speed "torpedo" racing car suddenly bumped into a vertical steel rail, jumped into the air, and fell into the auditorium, killing 2 people and injuring 1...
