Description

Technical Field

[0001] This utility model relates to the field of steel pipe technology, and in particular to a seamless steel pipe. Background Technology

[0002] In petrochemical production, seamless steel pipes are used to transport various chemical media, which are often corrosive, flammable, and explosive. Therefore, seamless steel pipes are required to have good corrosion resistance, sealing properties, and safety and reliability. To this end, a variety of corrosion-resistant seamless steel pipe materials have been developed, and advanced welding and anti-corrosion treatment technologies have been adopted. Seamless steel pipes can also be used as mechanical structural components. Seamless steel pipes need to have high strength, toughness, and wear resistance to withstand mechanical loads and friction. Therefore, according to different usage requirements, appropriate materials and production processes are selected to manufacture seamless steel pipe structural components that meet various performance requirements.

[0003] A search revealed Chinese Patent Publication No. CN221762940U, which discloses a seamless steel pipe, including a first steel pipe body and a second steel pipe body, and an adjustment and locking mechanism disposed inside the first steel pipe body and the second steel pipe body. The adjustment and locking mechanism includes a return spring fixedly installed inside the second steel pipe body. This seamless steel pipe utilizes a return spring, a movable plate, and a sliding rod. The return spring resets, causing the movable plate and sliding rod to spring back, which in turn moves the limiting rod until the U-shaped limiting rod engages with the L-shaped pin. This engagement of the limiting rod and pin secures the first and second steel pipe bodies, facilitating quick and easy connection and disassembly of multiple steel pipes. The discharge pipes located at the bottom of the first and second steel pipe bodies allow for the recovery of residues inside the pipes, increasing the flexibility and efficiency of the device. However, this invention does not consider that if the steel pipe is not long enough, subsequent work may be impossible, leading to extended working time and reduced efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a seamless steel pipe, which aims to improve the problem in the prior art that if the length of the steel pipe is insufficient, subsequent work cannot be carried out, thereby prolonging the working time and reducing work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seamless steel pipe, comprising a steel pipe one, a hollow sleeve slidably connected to the left side of the outer wall of the steel pipe one, a steel pipe two slidably connected to the left side of the inner wall of the hollow sleeve, a limiting post one slidably connected to the right side of the top of the outer wall of the hollow sleeve, a limiting ring one threadedly connected to the top of the outer wall of the limiting post one, and auxiliary blocks one fixedly connected to the left and right sides of the outer wall of the limiting ring one; a limiting post two slidably connected to the left side of the top of the outer wall of the hollow sleeve, a limiting ring two threadedly connected to the top of the outer wall of the limiting post two, and auxiliary blocks two fixedly connected to the left and right sides of the outer wall of the limiting ring two; an adjustment mechanism is provided at the bottom end of the steel pipe one, the adjustment mechanism being used to adjust the height of the steel pipe one.

[0006] Through the above technical solutions: the sliding connection between steel pipe one and hollow sleeve not only ensures the flexibility of the structure but also improves the overall stability and durability; the sliding connection between hollow sleeve and steel pipe two reflects the designer's ultimate pursuit of mechanical motion precision; the limiting post one ensures the precise stopping of the steel pipe assembly at a specific position; the threaded connection between limiting post one and limiting ring one further enhances the reliability of this function; the auxiliary block one not only provides additional support for limiting ring one but also enhances the stability of the entire device; the threaded connection between limiting post two and limiting ring two ensures precise control of the steel pipe assembly in another direction; the auxiliary block two provides additional support for limiting ring two; and the adjustment mechanism allows users to finely adjust the height of steel pipe one according to actual needs, reflecting the user-friendliness of the design.

[0009] Through the above technical solutions: the fixed ring and the steel pipe are slidably connected, ensuring a tight fit and flexible movement between the two; the fixed ring and the connecting column are fixedly connected, which is not only stable but also easy to install and maintain; the connecting column and the threaded column are threadedly connected, ensuring the reliability of the connection; the fixed block not only enhances the stability of the structure but also provides additional support points; the ball and the base are rotatably connected, making the entire device operate more smoothly and reducing friction.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the first steel pipe is provided with an anti-corrosion coating layer two, and the outer wall of the second steel pipe is provided with an anti-corrosion coating layer one.

[0012] Through the above technical solutions, the second anti-corrosion coating not only endows the steel pipe with excellent corrosion resistance, but also improves its overall durability. The first anti-corrosion coating ensures that the integrity of its structure and the reliability of its function can be maintained even in harsh environments.

[0013] As a further description of the above technical solution:

[0014] A sealing ring is fixedly connected to the outer left side of the outer wall of the steel pipe near the edge, and the outer wall of the sealing ring is fixedly connected to the right side of the inner wall of the hollow sleeve.

[0015] The above technical solutions ensure the sealing performance of the steel pipe assembly during operation, prevent possible liquid or gas leakage, and guarantee the safety and reliability of the equipment.

[0016] As a further description of the above technical solution:

[0017] A sealing ring is fixedly connected to the outer right side of the outer wall of the second steel pipe near the edge, and the outer wall of the sealing ring is fixedly connected to the left side of the inner wall of the hollow sleeve.

[0018] Through the above technical solution, the function of the sealing ring 2 is to ensure the sealing between the steel pipe and the hollow sleeve, and to prevent liquid or gas leakage.

[0019] As a further description of the above technical solution:

[0020] The bottom of the first limiting post is fixedly connected to a first fixing post, and the bottom of the second limiting post is fixedly connected to a second fixing post.

[0021] Through the above technical solution, the combined action of fixed column one and fixed column two ensures precise positioning and stable support of the entire device during operation, further enhancing the stability and accuracy of the structure.

[0026] The middle part of the outer wall of the first limiting post is slidably connected to the inner wall of the first steel pipe, and the middle part of the outer wall of the second limiting post is slidably connected to the inner wall of the second steel pipe.

[0027] The above technical solution not only ensures the flexibility of the structure, but also enhances the stability of the connection parts. The sliding connection between the second limiting column and the second steel pipe makes the entire device run more smoothly, reduces unnecessary friction and wear, and thus extends its service life.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, a steel pipe is inserted into the inner wall of a hollow sleeve, a limiting post and an auxiliary block are added, and the auxiliary block is pushed to make the limiting ring rotate and press the top of the hollow sleeve to fix the steel pipe. This process is repeated to fix the steel pipe in the hollow sleeve through the limiting post and the auxiliary block, thereby extending the steel pipe and preventing the subsequent work from being impossible due to insufficient length during use, which would affect work efficiency.

[0030] 2. In this utility model, to adjust the height of the steel pipe, it is necessary to push the fixing block so that it drives the rotating column to rotate. When the rotating column rotates, the threaded column will slowly rotate out from the inside of the connecting column, thereby pushing the connecting column upward. Due to the rotational connection between the ball and the base, the bottom remains stable when the rotating column drives the ball to rotate, thus realizing the adjustment of the height of the steel pipe, which facilitates the use of the staff and improves the practicality and adaptability of the steel pipe.

During the rotation, the threaded column (203) will slowly rotate out of the inside of the connecting column (202), that is, push the connecting column (202) upward. Since the ball (206) is rotatably connected to the base (207), the bottom is not affected when the rotating column (204) drives the ball (206) to rotate. This realizes the adjustment of the height of steel pipe 1 (1), which facilitates the use of the staff and improves the practicality and adaptability of steel pipe 1 (1).
