Description

Technical Field

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

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instrumentation, and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

[0003] The application number is CN202321076388.4, which discloses a bending-resistant stainless steel pipe, including a stainless steel pipe body, wherein a plurality of support rings are movably installed inside the stainless steel pipe body, the outer diameter of the support ring is matched with the inner diameter of the stainless steel pipe body, a plurality of reinforcing rods are embedded in the outer wall of the support ring, and the reinforcing rods are fixedly connected to the support ring, the outer wall of the support ring is provided with a receiving groove, the inside of the receiving groove is fixedly connected with a wear-resistant pad, the wear-resistant pad is matched with the receiving groove, and a reinforcing component is arranged inside the support ring. This bending-resistant stainless steel pipe, by arranging support rings and a plurality of reinforcing rods inside the stainless steel pipe body, can make the overall rigidity of the end and middle section of the stainless steel pipe body stronger under the action of the support rings and the reinforcing rods, and is not easily flattened or bent under the action of external forces, and can reduce accidental damage to the stainless steel pipe caused by external forces during installation, thereby saving the cost loss of the stainless steel pipe during installation.

[0004] The above document discloses a bending-resistant stainless steel pipe with the following defects: during use, the stainless steel pipe is usually designed with a longer diameter. When the steel pipe is conveying heavier materials, when the heavier materials pass through the middle end of the steel pipe, the weight of the materials presses on the middle end of the pipe. Since the middle part of the pipe has no protective structure and is relatively fragile, the materials may break the middle end of the pipe.

[0005] It can be seen from this that the existing anti-bending stainless steel pipe does not have the function of enhancing the tolerance of the middle end of the pipeline. It is necessary to improve the existing deficiencies and provide a function that can enhance the tolerance of the middle end of the pipeline. Summary of the invention

[0006] The purpose of the utility model is to provide a bending-resistant stainless steel pipe to solve the problems raised in the above-mentioned background technology.

The design of the bolts facilitates the disassembly and separation of the slider and the connecting ring block. When the slider is slid and removed from the pipeline, the positioning groove of the slider is at the sliding of the arc rod and the protrusion, and the connecting structure can be disassembled, thereby enhancing the practicality of the stainless steel pipe.

[0009] Furthermore, a pipe is provided on the lower surface of the arc rod, and the slider is slidably connected to the outer wall of the pipe. The purpose of this arrangement is that when the stainless steel pipe is used, the material is transported in the pipe, and the slider is slid and removed from the pipe, the positioning groove of the slider is in the sliding position of the arc rod and the protrusion.

[0010] Furthermore, a groove is provided on the outer wall of the middle part of the pipe, and limit blocks are provided on the inner walls of both sides of the bottom of the slider, and the two limit blocks are located on the inner wall of the groove.

[0011] Furthermore, a connecting annular block is provided on the lower surface of the two limit blocks, and the two ends of the connecting annular block overlap with the two limit blocks.

[0012] Furthermore, a positioning groove is provided on the outer wall of the side where the two limit blocks are close to each other, and a positioning groove is provided on the inner wall of the middle part of the connecting annular block. The purpose of such arrangement is that during the use of the stainless steel pipe, the protrusion is clamped in the positioning groove in the slider, so that the slider is fixed on the top outer wall of the pipe.

[0013] Furthermore, bolts are threadedly connected to the inner walls of both ends of the connecting annular block, and one end of the two bolts extends upward to the inner walls of the two limit blocks. The purpose of this arrangement is that during the use of the stainless steel pipe, the bolts fix the two so that the connecting structure is firmly installed on the pipeline structure, and the design of the bolts facilitates the disassembly and separation of the slider and the connecting annular block.
