Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a compression-resistant and deformation-resistant stainless steel pipe. Background Art

[0002] Stainless steel pipe is a hollow long strip of circular cross-section steel made of stainless steel material. It is widely used in construction, chemical industry, petroleum, medicine, food, beverage, shipbuilding, papermaking, electric power, nuclear industry, mechanical equipment and other fields.

[0003] As for the prior art, the patent with the patent authorization announcement number CN218294852U discloses a stainless steel pipe that is easy to splice, including a steel pipe body, a splicing pipe is arranged on the left side of the steel pipe body, and the diameter of the splicing pipe is smaller than the diameter of the steel pipe body; an engagement block is arranged on the inner side of the steel pipe body, the engagement block is fixedly connected to the inner wall of the steel pipe body, and the engagement block is correspondingly engaged with the outer side wall of the splicing pipe; a pulling block is arranged on the outer side of the steel pipe body, and a pull rope is fixedly connected to the bottom of the pulling block, the pull rope runs through the steel pipe body, and the pull rope extends to the inside of the engagement block. The stainless steel pipe that is easy to splice is engaged with the splicing pipe through the engagement block inside the steel pipe body, and the splicing operation is simple. When the spliced ​​steel pipes need to be separated later, the engagement block can be separated from the splicing pipe by pulling the pulling block, and the disassembly operation is simple and quick.

[0004] Although the stainless steel pipe in the above patent is simple to splice and the disassembly operation is also simple and quick, the stainless steel pipe has poor pressure resistance and is easily deformed when subjected to external force. In order to protect the stainless steel pipe from being damaged by human beings and save space, most of the stainless steel pipes currently used for water transportation are buried deep underground. However, due to the fact that they are buried deep in the soil, there will be more soil on the top of the stainless steel pipe, which causes the top of the stainless steel pipe to be under greater pressure. During long-term use, the stainless steel pipe will wear and cause the pipe wall to gradually become thinner. At this time, the top of the stainless steel pipe is more likely to be concave and deformed, causing damage to the stainless steel pipe. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a compression-resistant and deformation-resistant stainless steel pipe to solve the problems raised by the background technology, so that the steel pipe body has better compression resistance and is not easy to deform.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a compression-resistant and deformation-resistant stainless steel pipe, comprising a steel pipe main body, the inner wall of which is fixedly connected to a limiting ring, the interior of the steel pipe main body is rotatably connected to a rotating ring, a limiting groove is provided on the outer wall of the rotating ring, the limiting groove matches the limiting ring, and a support frame is fixedly connected to the inner wall of the rotating ring.

[0007] Furthermore, the support frame is arranged in a Y shape.

[0008] Furthermore, three connecting rods are provided between adjacent rotating rings, the connecting rods are equidistantly distributed, and the connecting rods are fixedly connected to the rotating rings.

[0009] Furthermore, both ends of the steel pipe body are provided with a clamping groove, a positioning frame is rotatably connected in the clamping groove, and the positioning frame is fixedly connected to the connecting rod.

[0010] Furthermore, the positioning frame is in a Y-shape, and the positioning frame corresponds to the supporting frame.

[0011] Furthermore, a threaded hole is provided at the end of the positioning frame, a bolt is connected to the inner thread of the threaded hole, and the end of the bolt abuts against the inner wall of the slot.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This type of compression-resistant and deformation-resistant stainless steel pipe provides support to the interior of the steel pipe body through a rotating ring and a support frame, thereby improving the compression resistance of the steel pipe body and making the steel pipe body less likely to deform. At the same time, the rotating ring is rotatably connected to the steel pipe body, thereby facilitating adjustment of the angle of the support frame and improving the supporting effect of the support frame.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-4A compression-resistant and deformation-resistant stainless steel pipe comprises a steel pipe body 1, the inner wall of the steel pipe body 1 is fixedly connected to a limiting ring 2, the inner part of the steel pipe body 1 is rotatably connected to a rotating ring 4, the outer wall of the rotating ring 4 is provided with a limiting groove 10, the limiting groove 10 matches the limiting ring 2, and the inner wall of the rotating ring 4 is fixedly connected to a supporting frame 5.

[0021] The compression-resistant and deformation-resistant stainless steel pipe in the utility model provides support to the interior of the steel pipe body 1 through the rotating ring 4 and the support frame 5, thereby improving the compression resistance of the steel pipe body 1 and making the steel pipe body 1 not easily deformed. At the same time, the rotating ring 4 is rotatably connected to the steel pipe body 1, so as to facilitate adjustment of the angle of the support frame 5 and improve the supporting effect of the support frame 5. In addition, the structure of the steel pipe body 1 is similar to a stainless steel pipe structure that is easy to splice and use, which is disclosed in the patent with patent authorization announcement number CN218294852U, so no further elaboration is made here.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the support frame 5 is arranged in a Y-shape. The support frame 5 arranged in a Y-shape has a better supporting effect.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, three connecting rods 6 are provided between adjacent rotating rings 4 , the connecting rods 6 are equidistantly distributed, and the connecting rods 6 are fixedly connected to the rotating ring 4 .

[0024] Specifically, multiple rotating rings 4 are connected into a whole through the connecting rod 6, so as to facilitate the adjustment of the rotating ring 4, so that the support frame 5 can maintain a vertical state or a horizontal state (the support frame 5 in the vertical state can improve the compressive resistance of the steel pipe body 1 in the vertical direction, and the support frame 5 in the horizontal state can improve the compressive resistance of the steel pipe body 1 in the horizontal direction).

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, both ends of the steel pipe body 1 are provided with a clamping groove 3, and a positioning frame 7 is rotatably connected in the clamping groove 3, and the positioning frame 7 is fixedly connected to the connecting rod 6.

[0026] Specifically, the positioning frame 7 and the rotating ring 4 are connected into a whole through the connecting rod 6 , so that the states of the rotating ring 4 and the supporting frame 5 can be adjusted through the positioning frame 7 .

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the positioning frame 7 is Y-shaped, and the positioning frame 7 corresponds to the support frame 5. The positioning frame 7 corresponds to the support frame 5, so that the state of the support frame 5 can be judged by observing the positioning frame 7.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a threaded hole 8 is formed at the end of the positioning frame 7 , and a bolt 9 is connected to the inner thread of the threaded hole 8 , and the end of the bolt 9 abuts against the inner wall of the slot 3 .

[0029] Specifically, after the positioning frame 7 and the support frame 5 are adjusted to appropriate positions, the positioning frame 7 can be fixed by tightening the bolts 9, thereby preventing the angle of the support frame 5 from changing, thereby improving the supporting effect of the support frame 5 and further enhancing the compressive resistance of the steel pipe body 1.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
