Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of iron accessories, in particular to an iron accessory with corrosion resistance function. Background Art
[0002] Iron accessories refer to various small metal parts that are used in the processing and production of iron products. Iron accessories are usually made of carbon steel, alloy steel, stainless steel and other materials. Carbon steel is cheap and suitable for mass production. Iron accessories are also widely used in power line transmission and transformation components, such as cross arms, clamps and hangers used in power lines, and joints, ladders, lightning rods, cable supports and other products used in substations, or non-standard components such as gantries and benchmarks used in other transportation projects and guardrails used in municipal engineering. In general, iron accessories are indispensable and important components in fields such as machinery manufacturing and construction engineering, and their types and uses are very wide.
[0003] Iron accessories play a vital role in various projects and structures. However, their welding positions and surfaces often become the "hardest hit areas" of corrosion. Welding is a key step in the manufacturing process of iron accessories, but the heat-affected zone and fusion zone generated during welding will cause significant changes to the metal structure. These areas experience high temperatures, causing changes in the metal lattice structure and redistribution of metal components, which in turn leads to an increase in electrode potential difference. When iron accessories are exposed to a corrosive environment, these areas with large potential differences will become the preferred attack points for corrosion, leading to the rapid spread of local corrosion.
[0004] In addition to changes in metal structure, residual stress and surface film damage may also be generated during the welding process. Residual stress is caused by uneven cooling of the welding area, which creates stress concentration areas inside the metal. These areas are more susceptible to corrosion, while surface film damage is due to high temperature and mechanical action during the welding process, which damages the protective film on the surface of the iron accessories and loses its original protective function, thereby exacerbating the occurrence of corrosion. In addition, the surface of iron accessories is also facing the threat of corrosion. In a humid, rainy or corrosive environment, the surface of iron accessories is easily exposed to moisture and corrosive substances, thereby inducing chemical reactions, leading to surface oxidation, rust and other phenomena. This corrosion will not only affect the appearance of the iron accessories, but more importantly, it will weaken their mechanical properties and structural stability, reducing their service life and safety.
[0005] Chinese patent document CN206332415U discloses an iron accessory including an upper plate and a lower plate, wherein the upper plate has a plurality of bolt holes penetrating the upper plate on its upper surface, and a first groove along the length direction of the upper plate is provided on its lower surface, wherein the first groove has a semicircular cross section; a second groove along the length direction of the lower plate is provided in the middle of the upper surface of the lower plate, wherein the first groove corresponds to the second groove in upper and lower positions, a wire is accommodated between the first groove and the second groove, and bolt holes are evenly distributed on both sides of the second groove; a plurality of U-shaped clips are provided at the lower part of the lower plate, wherein the U-shaped clips pass through the lower plate from bottom to top and are fixed to the lower plate by nuts; and the fastening bolts pass through the corresponding bolt holes on the upper plate and the lower plate to fix the upper plate and the lower plate together; however, the following defects still exist in the implementation process:
[0006] Although the device in the above document improves the connection method between the wire and the iron accessory, so that the force on the iron accessory is changed and cracks caused by concentrated force are avoided, the iron accessory in the above document does not have a corrosion-resistant function, which makes the device in the above document prone to corrosion during use. Utility Model Content
[0007] The purpose of the utility model is to provide an iron accessory with corrosion resistance function to solve the problems raised in the above background technology.
[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0009] An iron accessory with corrosion resistance comprises two iron accessory bodies; the two iron accessory bodies are fixedly connected by welding at one side close to each other, the two iron accessory bodies are symmetrically fixedly connected with a connecting plate 1 at one side close to the welding position, a plurality of connecting plates 1 are fixedly connected with a sheath together, a plurality of connecting plates 1 are fixedly connected with a sealing plate at one side away from the sheath, the opposite surfaces of the two connecting plates 1 at the same level are fixedly connected with a first limiting structure together, the two iron accessory bodies are symmetrically fixedly connected with a second limiting structure at one side away from the welding position, the opposite surfaces of the two second limiting structures at the same level are slidably connected with a zinc block structure together, and the zinc block structure is tightly fitted with the surface of the iron accessory body at one side close to the iron accessory body.
[0010] A further improvement of the technical solution of the utility model is that the surface of the iron accessory body is coated with a polyurethane coating layer.
[0011] The above technical solution is adopted. In this solution, since the polyurethane coating has excellent chemical corrosion resistance and can resist the erosion of various chemical substances such as acids, alkalis, and salts, a polyurethane coating layer is coated on the surface of the iron accessory body, thereby effectively preventing corrosion and rust on the surface of the iron accessory body.
[0012] A further improvement of the technical solution of the utility model is that the inner cavity of the sheath is closely fitted with the surfaces of the welding positions of the two iron accessory bodies.
[0013] By adopting the above technical solution, the inner cavity of the sheath is tightly fitted with the surface of the welding position of the two iron accessory bodies, so that the sheath can be used to reduce the chance of direct contact between the welding positions of the two iron accessory bodies and the corrosive environment, thereby slowing down the corrosion rate and extending the service life of the iron accessory body.
[0014] A further improvement of the technical solution of the utility model is that the first limiting structure includes a second connecting plate, the second connecting plate is fixedly connected to the first connecting plate at the same horizontal height, and a plurality of block structures are fixedly connected to the middle of the second connecting plate.
[0015] The above technical solution is adopted, in which a connecting plate 2 is provided, and then the connecting plate 2 is fixedly connected to a plurality of block structures, so that the position of the zinc block structure can be limited by the plurality of block structures to prevent the zinc block structure from being separated from the iron accessory body during use.

[0017] The above-mentioned technical solution is adopted, in which the outer shell is threadedly connected to the screw block, so that the position of the screw block in the inner cavity of the outer shell can be changed by rotating the screw block, and then the spring force on the protrusion is changed, so that the protrusion can fix the position of the zinc block structure or release the position of the zinc block structure, and then it is convenient to replace the corroded zinc block structure.
[0018] A further improvement of the technical solution of the utility model is that the zinc block structure includes a zinc plate, and a plurality of limiting grooves used in conjunction with the blocking structure are provided on the side of the zinc plate close to the blocking structure, and a connecting block is symmetrically fixedly connected to the side of the zinc plate close to the second limiting structure, and the connecting block is T-shaped.
[0019] The above technical scheme is adopted, in which a number of limit grooves are provided to facilitate the protrusion to fix the position of the zinc plate, and a number of connecting blocks are fixedly connected. Then, with the cooperation of the connecting blocks and the sliding grooves, it can be prevented that when the protrusion applies force to the zinc plate, the zinc plate is prevented from tilting up on the side away from the limit groove, thereby causing the gap between the contact surface of the zinc plate and the iron accessory body to increase, and then affecting the protection of the zinc plate to the iron accessory body.
[0020] A further improvement of the technical solution of the utility model is that a sliding groove is provided on a side of the second limiting structure close to the zinc plate, and the inner cavity of the sliding groove is slidably connected to the outer surface of the connecting block.

[0022] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0023] 1. The utility model provides an iron accessory with corrosion resistance function. The position of the sheath is fixed by a pair of connecting plates, and then the sheath can be used to protect the welding positions of the two iron accessory bodies, thereby reducing the chance of the welding positions of the two iron accessory bodies being in direct contact with the corrosive environment, thereby slowing down the corrosion rate and extending the service life of the iron accessory body. By fixing a sealing plate on the side away from the sheath, the sealing plate can be used to reduce the external moisture from entering the gap between the connecting plate and the sheath from the connection between the connecting plate and the sheath, and then causing corrosion to the welding positions of the two iron accessory bodies. By fixing a first limiting structure, the position of the zinc block structure can be fixed by the first limiting structure, and then the surface of the iron accessory body can be protected by the zinc block structure, thereby reducing the contact between the surface of the iron accessory body and moisture and corrosive substances, and reducing the external corrosion of the iron accessory body, thereby extending the service life of the iron accessory body.
[0024] 2. The utility model provides an iron accessory with corrosion-resistant function, which is threadedly connected to the shell through a screw block. Therefore, when it is necessary to fix the position of the zinc block structure, it is only necessary to turn the screw block downward to increase the force applied by the screw block to the spring on the protrusion, and then use the spring to push the protrusion toward the direction of the zinc block structure. Therefore, with the cooperation of the protrusion and the limiting groove, the position of the zinc block structure can be mechanically limited. When it is necessary to contact and fix the position of the zinc block structure, it is only necessary to turn the screw block upward to reduce the force applied by the screw block to the spring on the protrusion, and then the restraining force of the protrusion on the zinc block structure can be reduced, thereby facilitating the sliding removal of the corroded zinc block structure and then replacing it.
