[0001] The utility model relates to the field of stainless steel welded pipes, in particular to a stainless steel welded pipe with a spliced ​​portion reinforced. Background Art

[0002] Stainless steel welded pipe, referred to as welded pipe, is a steel pipe made by welding common steel or steel strip after curling and forming by a unit and a mold. The production process of welded steel pipe is simple, the production efficiency is high, the variety and specifications are many, and the equipment investment is small, but the general strength is lower than that of seamless steel pipe.

[0003] In practice, multiple welded pipes are usually spliced ​​together to increase their overall length, making it easier to transport and store while meeting different requirements for the length of the welded pipe.

[0004] Spliced ​​welded pipes can be cut and assembled in customized lengths according to specific site needs, which increases construction flexibility. However, the splices may become the weak link in the entire structure, resulting in a decrease in the overall structural strength. When subjected to external forces, the splices may be damaged first.

[0005] Therefore, how to strengthen the splicing parts of the stainless steel pipe welded pipes to improve the strength of the splicing parts of the stainless steel welded pipes spliced ​​together has become a problem to be solved urgently by those skilled in the art. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 6As shown, the utility model discloses a stainless steel welded pipe for reinforcing a joint, which is composed of a front tube body 1 and a rear tube body 2 in the shape of a cylinder extending front and back in the length direction. The front tube body 1 includes a matching section 11 on the rear side, and a mounting section 21 is provided on the front side of the rear tube body 2 and is sleeved on the circumference of the matching section 11. The front tube body 1 and the rear tube body 2 are positioned by inserting the matching section 11 into the mounting section 21. At this time, the front tube body 1 and the rear tube body 2 are welded together, and the front tube body 1 and the rear tube body 2 can be spliced ​​together. The front tube body 1 is fixedly installed with a positioning section 12 made of a deformable material such as rubber on the front side of the matching section 11. A plurality of mounting plugs 211 are provided at intervals in the circumference of the mounting section 21. The positioning section 12 corresponds to each mounting plug 211. Both are provided with installation slots 121. After the matching section 11 of the front tube body 1 is installed into the installation section 21 of the rear tube body 2, a force is applied to the positioning section 12 to cause it to deform, so that each installation plug 211 on the installation section 21 can be forcibly squeezed into the corresponding installation slot 121. After the matching of each installation plug 211 and the installation slot 121 is completed, the preliminary connection between the front tube body 1 and the rear tube body 2 is realized. While facilitating welding to achieve the fixation of the front tube body 1 and the rear tube body 2, if the welding at the joint is damaged, at this time, since each installation plug 211 is located in the corresponding installation slot 121, the strength of the joint between the front tube body 1 and the rear tube body 2 can be further increased, thereby reducing the situation where the joint is first damaged when subjected to external force.

[0027] Among them, each of the mounting blocks 211 is arranged in a stepped shape with a top width smaller than a bottom width, and the side of each mounting block 211 extending from the top surface to the bottom surface is arranged in an inclined surface. Since the width of the top of each mounting block 211 is smaller than the width of the bottom, when each mounting block 211 is installed into the mounting slot 121 corresponding to the positioning section 12, the top of each mounting block 211, that is, the part with the smallest width, first enters each mounting slot 121, thereby allowing each mounting block 211 to enter the corresponding mounting slot 121 more smoothly.

[0028] Preferably, a deformation groove 122 is provided on the rear side of the positioning section 12, and the rear side of the deformation groove 122 is open. Since the deformation groove 122 is provided on the rear side of the positioning section 12, the wall thickness of the positioning section 12 is greatly weakened, so that when each mounting block 211 is inserted into the corresponding mounting slot 121, the positioning section 12 can be more smoothly applied with force so that it can be bent outward so that the mounting block 211 can be inserted into the mounting slot 121.

[0029] In addition, it also includes a connecting sleeve 3 sleeved on the installation section 21, and a disassembly groove 31 is provided on the connecting sleeve 3. The front side of the connecting sleeve 3 is detachably connected to the positioning section 12 by means of buckles, bolts, etc., and the rear side of the connecting sleeve 3 is detachably connected to the installation section 21 by means of buckles, bolts, etc. 1. Since the connecting sleeve 3 is provided with a disassembly groove 31, the connecting sleeve 3 can be sleeved on the circumference of the installation section 21 by bending the disassembly groove 31, so that the connecting sleeve 3 can be easily installed on the installation section 21. At the same time, since the connecting sleeve 3 is provided with a disassembly groove 31, the connecting sleeve 3 can be easily installed on the installation section 21. The rear side of the connecting sleeve 3 is connected to the positioning section 12, and the front side is connected to the mounting section 21, so the connecting sleeve 3 can be stably fixed on the mounting section 21; 2. Since the front and rear sides of the connecting sleeve 3 are respectively connected to the front tube body 1 and the rear tube body 2, if the joint is first damaged by external force, the front tube body 1 and the rear tube body 2 can still be connected together due to the existence of the connecting sleeve 3, that is, the strength of the front tube body 1 and the rear tube body 2 at the joint is increased, so that the front tube body 1 and the rear tube body 2 spliced ​​together after receiving external force can be stably installed together without disconnection.

[0030] Among them, the installation section 21 is provided with a plurality of positioning posts 212 at circumferential intervals, and the connecting sleeve 3 is provided with positioning grooves 32 corresponding to each positioning post 212. Since the connecting sleeve 3 is provided with positioning grooves 32 corresponding to each positioning post 212, after one of the positioning grooves 32 is located directly above the positioning post 212, the matching groove 125 can be opened so that each positioning groove 32 of the connecting sleeve 3 mounted on the installation section 21 at this time is respectively inserted into the corresponding positioning post 212, so that in the absence of external force, the connecting sleeve 3 can be stably connected to the installation section 21 and will not rotate.

[0031] Among them, the connecting sleeve 3 is provided with a plurality of limit members 33 made of rubber or other materials that are easy to deform. The limit members 33 include a fixed section 331 extending forward and backward in the length direction and a limit section 332 that is perpendicular to the fixed section 331 in the length direction. The positioning section 12 is provided with a fixing groove 123 corresponding to the fixed section 331, and a limit groove 124 corresponding to the limit section 332. After the connecting sleeve 3 is sleeved on the mounting section 21 to realize the cooperation between each positioning column 212 and the positioning groove 32, since the limit member 33 is easy to deform, after force is applied to the limit section 332 of the limit member 33, the limit section 332 can enter the limit groove 124 after forcibly crossing the fixing groove 123, so that the rear side of the connecting sleeve 3 can be stably assembled with the positioning section 12.

[0032] Preferably, the positioning section 12 is located at the front side of the limiting groove 124 and is provided with a matching groove 125 which is interconnected with the limiting groove 124. Therefore, before the limiting section 332 is installed into the limiting groove 124, the limiting section 332 is bent so that it is located in the length extension direction of the fixing section 331 so that it can enter the matching groove 125 more smoothly. When the limiting section 332 enters the matching groove 125, the limiting section 332 loses the force and restores its original shape to be located in the limiting groove 124 and resist against the positioning section 12. Therefore, the matching section 11 can provide convenience for the limiting section 332 to be installed into the positioning section 12 when it is deformed under force.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
