[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 instruments, and mechanical structural components. When transporting liquids or gases, due to the limited transportation length of a single stainless steel pipe, multiple stainless steel pipes are generally spliced ​​end to end to form the required transportation length.

[0003] As in the prior art, the patent with the patent authorization announcement number CN219606303U discloses an assembled stainless steel pipe fitting, including a short pipe and an independent butt pipe. In this assembled stainless steel pipe fitting, an independent short pipe and a butt pipe are provided, and the two ends of the short pipe are plug-connected with the butt pipe. An independent base rod is provided, and connecting rods are hinged at both ends of the base rod. A hanging shaft is fixedly connected to the outer peripheral wall of the short pipe, and a waist-shaped hole detachably connected to the hanging shaft is opened in the middle of the base rod. A limit plate is sleeved on the outer peripheral wall of the butt pipe, and a hook head for hooking the limit plate is provided at one end of the connecting rod. When the base rod is controlled to be twisted into a Z shape with the connecting rod, opposite pulling forces are applied to the butt pipes at both ends of the short pipe, so that the short pipe and the butt pipe are tightly connected. An independent U-shaped bayonet is provided, and the U-shaped bayonet and the short pipe are combined to lock the connecting rod and the base rod. At this time, the short pipe and the butt pipe are in a state of fastened connection, and there is no need to screw or use bolts to connect, which greatly improves the convenience of pipeline docking and disassembly.

[0004] Although the stainless steel pipe in the above patent does not need to be screwed or bolted when connected, which greatly improves the convenience of pipe docking and disassembly, the stainless steel pipe fittings need to be used in conjunction with short pipes, butt pipes, base rods, connecting rods and U-shaped pins when connected, and if any of the accessories is missing during use, the stainless steel pipe fittings cannot be connected normally. Therefore, the device has great limitations and is inconvenient to use. Utility Model Content

[0018] 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.

[0019] See also Figure 1-4 A fabricated stainless steel pipe comprises a stainless steel pipe body 1, one end of which is fixedly connected with a plurality of wedge blocks 2, which are evenly distributed, and the other end of the stainless steel pipe body 1 is rotatably connected with a collar 4, one side of the collar 4 is fixedly connected with a plurality of clamping blocks 5, which match the wedge blocks 2, and a side of the collar 4 away from the clamping blocks 5 is provided with a plurality of extrusion fixing components connected with the stainless steel pipe body 1.

[0020] When the assembled stainless steel pipe in the utility model needs to connect two stainless steel pipe bodies 1 together, it is only necessary to first stagger the clamping block 5 and the wedge block 2, and then align the ends of the two stainless steel pipe bodies 1, move the stainless steel pipe body 1 to insert the clamping block 5 into the gap between the wedge blocks 2, and then rotate the collar 4 to make the clamping block 5 butt against the wedge block 2. Since the contact surface of the wedge block 2 of the clamping block 5 is an inclined surface, during the rotation of the collar 4, the clamping block 5 will push the wedge block 2 toward the direction of the collar 4, so that the ends of the two stainless steel pipe bodies 1 are tightly attached, and finally the collar 4 can be fixed by squeezing the fixing assembly. The above structures are all connected to the stainless steel pipe body 1, are not easy to lose, and the operation process is simple and convenient.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, a positioning ring 3 is fixedly connected to one end of the stainless steel pipe body 1 away from the wedge block 2 , and a positioning groove 401 matching the positioning ring 3 is formed on the inner side of the collar 4 .

[0022] Specifically, the collar 4 is restricted by the positioning ring 3 so that the collar 4 can rotate while ensuring that the collar 4 does not separate from the stainless steel pipe body 1 .

[0023] like Figure 1 , Figure 3 and Figure 4As shown, the extrusion fixing assembly includes a positioning plate 9, a threaded rod 10 and an extrusion block 11. A plurality of positioning plates 9 are fixedly connected to the outer wall of the stainless steel pipe body 1. The threaded rod 10 is threadedly connected to the positioning plate 9. The threaded rod 10 is rotatably connected to the extrusion block 11 on the side close to the collar 4. The extrusion block 11 is arranged in a triangular shape. A plurality of extrusion grooves 8 matching the extrusion block 11 are provided on the side of the collar 4 close to the positioning plate 9.

[0024] Specifically, after the clamping block 5 passes through the gap between the two wedge blocks 2 and the collar 4 is rotated at a certain angle, the threaded rod 10 is rotated at this time, and the threaded rod 10 will push the extrusion block 11 into the extrusion groove 8. Since the extrusion block 11 is arranged in a triangle, the extrusion block 11 will push the collar 4 to rotate (the pushing direction is consistent with the direction of rotating the collar 4 to make the clamping block 5 and the wedge block 2 abut against each other), so that the clamping block 5 and the wedge block 2 fit more closely, so that the two stainless steel pipe bodies 1 can be connected more tightly.

[0025] like Figure 1 and Figure 3 As shown, a hand wheel 12 is fixedly connected to one side of the threaded rod 10 away from the extrusion block 11. It is simpler and more labor-saving to drive the threaded rod 10 to rotate by the hand wheel 12.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a slot 7 is provided on a side of the wedge block 2 away from the stainless steel pipe body 1 , and an insert rod 6 matching the slot 7 is fixedly connected to one end of the stainless steel pipe body 1 away from the wedge block 2 .

[0027] Specifically, when the two stainless steel pipe bodies 1 are close to each other, the insert rod 6 will be inserted into the slot 7, thereby limiting the relative position of the two stainless steel pipe bodies 1 to prevent the stainless steel pipe bodies 1 from rotating together when the ring 4 rotates, causing the block 5 to be unable to abut against the wedge block 2.

[0028] 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.
