Description

Technical Field

[0001] This utility model relates to the field of screw rod technology, specifically to a rust-resistant high-strength stainless steel screw rod. Background Technology

[0002] A screw rod is a cylindrical part with a spiral line on its surface. It is mainly used for fixing, connecting or transmitting on cylindrical working parts with high concentricity. It can be divided into connecting screws, fixing screws and transmission screws according to its use. It is commonly used in machinery, construction and other industrial fields.

[0003] Currently, screw rods are usually stored in storage boxes. However, during long-term contact with the external environment, the surface of the screw rods is prone to moisture and corrosion. This often requires personnel to perform rust removal before using the screw rods, causing some inconvenience. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1:

[0025] Please see Figures 1-5 As shown, this utility model provides a rust-proof high-strength stainless steel screw bar, including a screw bar body 1. The screw bar body 1 includes a high-strength stainless steel layer 12 and a rust-proof protective layer 11. The rust-proof protective layer 11 includes a galvanized rust-proof layer 111 and a phosphated rust-proof layer 112. An oil-impregnated sponge sleeve 8 is fitted on the surface of the screw bar body 1. A protective sleeve body 2 is fitted on the outer surface of the oil-impregnated sponge sleeve 8. Protective plugs 4 are fitted between the two ends of the outer surface of the protective sleeve body 2 and the two sides of the screw bar body 1.

[0026] In this technical solution, by setting up the protective sleeve body 2, the protective plug 4, the oil-impregnated sponge sleeve 8, the anti-rust protective layer 11, the phosphate anti-rust layer 112 and the galvanized anti-rust layer 111, a good anti-rust protection is formed on the surface and around the screw rod body 1, which effectively avoids the surface of the screw rod body 1 from being corroded during storage or use, and greatly improves the anti-rust performance of the screw rod body 1, making it easier for personnel to use.

[0027] Example 2:

[0028] Based on Embodiment 1, this utility model is as follows: Figure 3As shown, the protective case body 2 includes a polyurethane coating 21, a kraft paper layer 22, and a polypropylene film layer 23. The surface of the polyurethane coating 21 is coated on the outer surface of the kraft paper layer 22, and the outer surface of the polypropylene film layer 23 is adhered to the inner surface of the kraft paper layer 22.

[0029] In this technical solution, the polyurethane coating 21 forms a good wear-resistant protective effect on the surface of the kraft paper layer 22, effectively reducing the chance of the kraft paper layer 22 getting damp and worn. The polypropylene film layer 23 forms a good anti-oil protection on the inner surface of the kraft paper layer 22, preventing the anti-rust oil in the oil-impregnated sponge sleeve 8 from staining the kraft paper layer 22.

[0030] Example 3:

[0031] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a U-shaped limiting frame 5 is fixedly connected to both ends of the outer surface of the protective plug 4. An elastic connecting strip 3 is sleeved between the surface of the U-shaped limiting frame 5 and the outer surface of the protective plug 4. The surface of the elastic connecting strip 3 is movably connected to the outer surface of the protective sleeve body 2. A label 6 is pasted on the upper end of the outer surface of the protective plug 4. The label 6 is rectangular in shape. A rubber ring 7 is fixedly connected to the inner surface of the protective plug 4. The outer surface of the rubber ring 7 is movably connected to the outer surface of the protective sleeve body 2. The surface of the phosphated anti-rust layer 112 is fixedly connected to the outer surface of the high-strength stainless steel layer 12. The surface of the galvanized anti-rust layer 111 is fixedly connected to the surface of the phosphated anti-rust layer 112.

[0032] In this technical solution, the U-shaped limiting frame 5 and the elastic connecting strip 3 can effectively fix the protective caps 4 on both sides of the screw rod body 1, preventing the protective caps 4 from falling off during use. The label paper 6 makes it easy for personnel to mark the model of the screw rod body 1 for easy retrieval later. The rubber ring 7 effectively improves the sealing performance between the protective caps 4 and the protective sleeve body 2.

[0033] The working principle of this utility model is as follows: By setting up the protective sleeve body 2 and the protective plug 4, the surrounding area can be effectively protected during the storage of the screw rod body 1, avoiding direct contact between the screw rod body 1 and the external environment, which would lead to moisture and corrosion. By setting up the oil-impregnated sponge sleeve 8, since the inside of the oil-impregnated sponge sleeve 8 absorbs a certain amount of rust-preventive oil, it can be applied to the surrounding surface during the storage of the screw rod body 1, effectively isolating the surface of the screw rod body 1 from the air, thereby greatly improving the rust-preventive performance of the surface of the screw rod body 1. At the same time, by setting up the rust-preventive protective layer 11, since both the phosphate rust-preventive layer 112 and the galvanized rust-preventive layer 111 in the rust-preventive protective layer 11 have good rust-preventive effects, a double-layer rust-preventive protection is formed on the surface of the screw rod body 1, thereby effectively reducing the probability of surface corrosion of the screw rod body 1 during use, which is beneficial to personnel.
