Fastener for protecting body paint on automobile door lock body

Abstract

The invention discloses a fastener for protecting body paint on an automobile door lock body. The fastener comprises a screw body and a protection sleeve which are integrally formed. The screw body ismachined and manufactured through stainless steel, and the protection sleeve is made of a nylon 66 material. By means of the fastener, damage of the fastener for an automobile to the body paint of the automobile can be obviously changed; the screw head is wrapped by the protection sleeve made of the nylon 66 material, and the nylon 66 material is resistant to impacting, can continuously bear force and do not crack and is good in ductility; and the contact face of a screw and the body paint surface is completely covered, and it is guaranteed that during screw assembling, the assembly torque requirement is met, and meanwhile the body paint is not destroyed. The fastener is simple in structure, the product quality is greatly improved, meanwhile, the attractive appearance of the automobile isguaranteed, and the fastener has high practicality.

Description

Technical field: [0001] The invention relates to a fastener for protecting vehicle body paint at a lock body of an automobile door, which belongs to the technical field of automobiles. Background technique: [0002] Fasteners fasten and connect two or more parts or structures into a whole. They are widely used in various industries. Machines and equipment of all sizes cannot do without them, especially in the connection of various parts of automobiles. Use frequently. The heads of existing fasteners have different shapes, including hexagonal flange bolts, cross-recessed pan head screws, cross-recessed countersunk head screws, etc., all of which are metal products. [0003] The general production process of existing fasteners: disc element, annealing, pickling, thread drawing, heading, tooth rolling, heat treatment, electroplating. [0004] In existing automobiles, when metal screws are in direct contact with the surface of the automobile body, the screws will destroy the p...

AI Technical Summary

Problems solved by technology

The reason for this situation is that the paint on the surface of the car body is uniform and thin, and the screws are metal products. When the screws that are in direct contact with the car body are assembled, due to the torque requirements of the assembly screws, the screws rub against the paint on the car body surface, and the paint on the car body falls off. Affect the appearance, and the protective effect of the paint on the body is reduced, affecting the service life of the car
