Description

Metal fixing member coated with integral insulating resistance film layer and process thereof

The present invention relates to a metal fixing member, and more particularly to a metal fixing member which forms an insulating resistive film layer on a metal body by means of dip forming.

Generally speaking, various routes (Cable routes) are usually installed in buildings as engineering pipes for water pipes, drain pipes, electric wires and the like of fire-fighting equipment. The materials of the pipelines may also be plastic according to the purpose of use. (PVC) or metal (RSG, EMT), although the engineering pipeline is not the main body of the building, it is an important key to the success of the project.

According to the different design requirements of the building, the pipelines can be close to the wall or suspended from the ceiling. Since the pipelines themselves have a certain weight, the manufacturer usually uses a plurality of metal fasteners (or metal brackets). ) to hold each of the pipes so that each of the pipes can be stably positioned at an intended position of the operator. However, since the surface of the metal fastener is mostly smooth, when the pipeline is shaken due to external factors (such as earthquakes, external force collisions, etc.), the metal fastener has no shock absorption or anti-slip effect. However, the displacement of the pipeline cannot be avoided. In addition, most of the metal fasteners are exposed to the air, which is prone to rust. In particular, the weather in Taiwan is relatively humid. Therefore, users often need to repeatedly inspect each metal fastener to prevent it. The metal fastener rusts and breaks, causing the pipe to fall or be damaged.

In order to solve the aforementioned problems, some manufacturers will provide an insulation on the surface of the metal fasteners. However, the applicant found that the manufacturer usually produces the metal fastener body and the insulating member separately, and then the insulating member is sleeved on the metal fastener body, which not only causes slow production and greatly increases the labor cost. At the same time, the insulating member needs to be opened with a slit to be unfolded and sleeved on the metal fastener body, so that the insulating member is easily buckled from the metal buckle during the use process due to pipeline sway or other external force factors. The main body is detached, and the original protective effect of the insulating member is lost. In addition, although some manufacturers use the heat shrinkable film as the insulating member, the manufacturer still needs to sleeve each heat shrinkable film on the metal fastener body one by one, and then blow the heat shrinkable film with hot air. It will still increase the complexity of the work. In particular, when the metal fastener body has multiple bends, the excessive portion of the heat shrinkable film is deposited on the aforementioned bend, and the manufacturer does not easily make the metal fastener. The surface (ie, the heat shrink film) remains flat.

In summary, the existing metal fasteners still have many defects when they are provided with insulating members. Therefore, how to design a metal fastener with good insulating members to provide better user experience, that is, It is an important subject to be explored by the present invention.

In order to stand out in the highly competitive market, the inventors have relied on the rich practical experience of designing, processing and manufacturing all kinds of metal fasteners for many years, and adhere to the spirit of research excellence, after long-term efforts and research. After that, a metal fixture coated with an integrally formed insulating resistive film layer of the present invention and a process thereof have been developed, and the production yield of the metal fastener is effectively improved by the present invention.

An object of the present invention is to provide a metal fixing member integrally coated with an insulating resistive film layer, comprising a metal body and an insulating resistive film layer, wherein the insulating resistive film layer is integrally formed by dip forming Overlying at least a portion of the surface of the metal body.

Another object of the present invention is to provide a process for the foregoing metal fixing member, which can perform a surface treatment process on the metal body to clean the surface attachment of the metal body, and then perform the first step on the metal body. a baking process for keeping the surface of the metal body dry, and then subjecting the metal body to a dipping process to immerse the metal body in a dipping tank, wherein the dipping tank contains a mixture of plastic powder and solvent Insulating thick material, when the metal body is immersed in the dipping tank, at least a part of the surface of the metal body can adhere to the insulating thick material, and finally, the metal body is subjected to a second baking process to make the metal The insulating thick body on the surface of the body can be solidified to form the insulating resistive film layer, so that the insulating resistive film layer can be conveniently formed on the surface regardless of the shape of the metal body.

A further object of the present invention is that after the metal body performs the first baking process, an adhesive layer is disposed on at least a part of the surface of the metal body, and then the metal body is subjected to the dipping process. The insulating resistance film layer can be more tightly fixed to the metal body.
