Description

Technical Field

[0001] This utility model relates to the field of stainless steel seamless pipe technology, specifically to a stainless steel seamless pipe with a heat insulation structure. Background Technology

[0002] Stainless steel seamless pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. The thicker the wall, the more economical and practical it is; conversely, the thinner the wall, the higher the processing cost. The manufacturing process of this product determines its limitations. Generally, seamless steel pipes have low precision: uneven wall thickness, low surface gloss on the inner and outer surfaces, high cost per length, and the presence of pits and black spots on the inner and outer surfaces that are difficult to remove; its inspection and shaping must be done offline. Therefore, it demonstrates its superiority in high-pressure, high-strength, and mechanical structural applications.

[0003] In some applications, stainless steel seamless pipes are fitted with insulation sleeves on their outer walls to improve their thermal insulation performance. However, existing stainless steel seamless pipes do not have a limiting structure when connected to the insulation sleeve, which means that the insulation sleeve cannot be effectively limited when it is fitted onto the outer wall of the stainless steel seamless pipe. Utility Model Content

[0004] The purpose of this utility model is to provide a seamless stainless steel tube with a heat insulation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a seamless stainless steel pipe with a heat insulation structure, comprising a stainless steel pipe body, a heat insulation sleeve fitted on the outer wall of the stainless steel pipe body, and a plurality of travel limiting grooves evenly spaced on the outer wall of the stainless steel pipe body.

[0006] The outer wall of the insulation sleeve is fitted with several hoops at equal intervals.

[0007] Preferably, a plurality of limiting rings are provided at equal intervals on the inner wall of the insulation sleeve, and the limiting rings are adapted to the travel limiting groove.

[0008] Preferably, threaded holes are provided at both the top and bottom of the hoop.

[0009] Preferably, a lead screw is threaded into the threaded holes at the top and bottom of the hoop.

[0010] Preferably, the end of the lead screw away from the hoop is fixedly connected to a toggle block, and the end of the lead screw passing through the threaded hole has an arc-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the stainless steel seamless pipe with heat insulation structure of this utility model has a simple structure and is easy to use. By opening a matching travel limiting groove on the outer wall of the stainless steel pipe body corresponding to the limiting ring inside the heat insulation sleeve, the limiting ring can be locked inside the travel limiting groove, so that the heat insulation sleeve can be stably fitted on the outer wall of the stainless steel seamless pipe body.

[0012] Furthermore, the set hoop can reinforce the connection between the limiting ring and the travel limiting groove, and the threaded rod inserted on the hoop can abut against the insulation sleeve, thereby making the connection between the insulation sleeve and the stainless steel pipe body more stable.

[0019] 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.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a seamless stainless steel pipe with a heat insulation structure, including a stainless steel pipe body 1, a heat insulation sleeve 2 sleeved on the outer wall of the stainless steel pipe body 1, and a plurality of travel limiting grooves 3 evenly spaced on the outer wall of the stainless steel pipe body 1.

[0021] Several hoop rings 5 ​​are evenly spaced on the outer wall of the insulation sleeve 2.

[0022] Several limiting rings 4 are evenly spaced on the inner wall of the insulation sleeve 2, and the limiting rings 4 are adapted to the travel limiting groove 3. The limiting rings 4 can be snapped into the inside of the travel limiting groove 3, so that the insulation sleeve 2 can be stably fitted onto the outer wall of the stainless steel pipe body 1.

[0023] The top and bottom of the hoop 5 are both provided with threaded holes 6.

[0024] Both the top and bottom threaded holes 6 of the hoop 5 are threaded with lead screws 7.

[0025] The end of the lead screw 7 away from the hoop 5 is fixedly connected to a toggle block, and the end of the lead screw 7 that passes through the threaded hole 6 has an arc-shaped structure.

[0026] Specifically, when using this utility model, an insulation sleeve 2 made of insulation cotton is fitted onto the outer wall of the stainless steel pipe body 1. The insulation sleeve 2 can insulate the stainless steel pipe body 1. When the insulation sleeve 2 slides along the stainless steel pipe body 1, the limiting ring 4 on its inner wall can be engaged with the inside of the travel limiting groove 3, thereby limiting the distance between the insulation sleeve 2 and the stainless steel pipe body 1. After the insulation sleeve 2 is installed, it can be reinforced by a hoop 5. The threaded rod 7 on the hoop 5 is tightened. During the tightening process, the threaded rod 7 can push the limiting ring 4 on the insulation sleeve 2 to stably fit into the inside of the travel limiting groove 3, thereby resisting the insulation sleeve 2 and making the connection between the insulation sleeve 2 and the stainless steel pipe body 1 more stable.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
