Preferably, the coating layer material is water-based antirust paint.

Preferably, the bolt film material is a PVC material.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses a, through the setting of bolt membrane, can effectually prevent the damage that causes in the transportation collision friction between the bolt for the bolt secondary condition such as corrosion appears and influences subsequent use.

2. The utility model discloses a, through the setting of anticorrosive coating, for the chemical activity nature of zinc is high, when taking place the chemical attack, what corroded earlier is zinc, and the oxide of zinc is more compact again, can prevent further oxidation. The corrosion resistance is effectively enhanced.

3. The utility model discloses a, through the setting in dope layer, because of paint has very strong coating adhesive force, thereby can be fine adhere to and form a protection film on the surface, can effectively completely cut off with the air contact, prevent other materials and metal to take place chemistry or electrochemical reaction to play fine rust-resistant effect.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an accurate bolt for electronic product, includes screw rod 1, 1 upper ends of screw rod are provided with bolt head 2, screw thread 3 has been seted up to bolt body outer wall, the surface of screw rod 1, bolt head 2 and screw thread 3 all is provided with anticorrosive coating 4, anticorrosive coating 4's surface is provided with dope layer 5, 5 surfaces of dope layer are provided with bolt membrane 6.

Specifically, the screw rod 1 and the bolt head 2 are made of carbon steel, and the device is easy to smelt and manufacture.

Specifically, the bolt head 2 is a hexagon socket head, and the arrangement can reduce the phenomenon of thread slipping.

Specifically, the anti-corrosion layer 4 is made of hot galvanizing, zinc can be corroded firstly, and the zinc oxide is dense, so that further oxidation can be prevented, and the corrosion resistance is effectively enhanced.

Specifically, the coating layer 5 is made of water-based antirust paint, and the coating layer can effectively isolate contact with air and prevent other substances from chemically or electrochemically reacting with metals, so that a good antirust effect is achieved.

Specifically, 6 materials of bolt membrane are the PVC material, and this sets up the damage that can effectually prevent collision friction and cause between the bolt in the transportation for the secondary condition such as corrosion appears in the bolt influences subsequent use.

The working principle is as follows: tear bolt membrane 6 to this use of precision bolt for electronic product, bolt membrane 6 is made by the PVC material, its weight is frivolous, attach the damage that can effectually prevent collision friction between the bolt in the transportation and cause on the surface, make the bolt appear the corrosion inferior goods condition influence subsequent use, the phenomenon of smooth silk often can appear in the process of using of bolt, the smooth silk just is not good lax appearing, bring very big resistance for work, should use neotype bolt head 2 to use interior hexagonal molding, the appearance of smooth silk has been reduced, and anticorrosive coating 4 is the galvanizing coat, the chemical liveliness of zinc is high, when taking place chemical corrosion, the earlier corruption is zinc, the oxide of zinc is more compact again, can prevent further oxidation. The corrosion resistance is effectively enhanced, the service life is prolonged, the coating layer 5 is made of water-based antirust paint through the arrangement of the coating layer 5, the paint has strong coating adhesive force, can be well attached to the surface to form a protective film, can be effectively isolated from contacting with air, and prevents other substances from carrying out chemical or electrochemical reaction with metal, so that a good antirust effect is achieved, and the using process of the precision bolt for the electronic product is completed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
