Technical Field

[0001] The utility model relates to the technical field of precision steel pipes, in particular to a precision steel pipe that is easy to disassemble. Background Art

[0002] Precision steel pipe is a high-precision steel pipe material obtained by cold drawing or hot rolling. Precision steel pipes that are easy to disassemble usually refer to those steel pipes that are designed to be easy to separate and assemble. They are often used in situations where flexible assembly or maintenance is required. Such steel pipes usually have standardized sizes and connection methods.

[0003] When existing precision steel pipes are in use, they are mostly connected by threaded connection, which facilitates quick assembly and disassembly on site. However, the threaded connection between the two steel pipes lacks protective devices. After long-term use, dust easily accumulates at the connection, making it easy for dust to enter the interior from the connection, causing corrosion and reducing the service life. Therefore, to address the above problem, we have proposed a precision steel pipe that is easy to disassemble. Utility Model Content

[0004] The purpose of the utility model is to provide a precision steel pipe that is easy to disassemble, so as to solve the problem that the threaded connection between two steel pipes lacks a protective device, and after long-term use, the connection is prone to dust accumulation, making it easy for dust to enter the interior from the connection, causing corrosion and reducing the service life.

[0007] Preferably, the first steel pipe and the second steel pipe have the same outer diameter, the right end surface of the first steel pipe and the left end surface of the second steel pipe are in contact with each other, the sealing gasket is located inside the annular groove, and the sealing gasket has a circular ring shape.

[0008] Preferably, the number of the support plates is two, the number of the damping sleeves is two, and the number of the connecting columns is two.

[0009] Preferably, there are two handles, each handle is located at the left end of the support plate, the first annular plate is located outside the first steel tube, and the second annular plate is located outside the second steel tube.

When the first steel pipe and the second steel pipe are spirally connected by the external threaded sleeve, the sealing gasket is located inside the annular groove, and the left end surface of the sealing gasket is tightly fitted with the inner wall of the annular groove, thereby realizing the primary sealing of the connection between the first steel pipe and the second steel pipe. Then, the rubber elastic protective sleeve is sleeved on the connection between the first steel pipe and the second steel pipe, thereby protecting the secondary sealing of the connection between the first steel pipe and the second steel pipe at the same time, thereby reducing the accumulation of dust at the connection between the first steel pipe and the second steel pipe, preventing dust from entering the interior through the connection and causing corrosion, thereby extending the service life. By providing the first annular plate, the fixing ring, the cleaning block, the felt cloth and the second annular plate, After the steel pipe and the second steel pipe are spirally connected by the external threaded sleeve, it is necessary to push the handle to the right, and the handle drives the connecting column to move to the right.
