Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe technology, specifically to a pluggable seamless steel pipe. Background Technology

[0002] Seamless steel pipes are made by piercing a single round steel bar, and are steel pipes without weld seams on their surface. Based on the production method, seamless steel pipes can be classified into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and jacking pipes, etc.

[0003] Patent CN221171157U discloses a pluggable seamless steel pipe, which includes a first seamless steel pipe, a sealing ring installed at one end of the first seamless steel pipe, and a second seamless steel pipe installed on one side of the sealing ring. The inner side of the end of the first seamless steel pipe that is in contact with the sealing ring is provided with an internal thread. The device uses the tightening between the threaded post and the internal thread to make the sealing ring fit between the first seamless steel pipe and the second seamless steel pipe. At the same time, one end of the threaded post is tightly fitted with one end of the limiting ring, thereby ensuring the sealing between the two pluggable seamless steel pipes.

[0004] However, this device uses a combination of a locking block and a sleeve to engage threaded posts and internal threads for a double-layer connection. While this significantly improves the stability of the seamless steel pipes after connection, the direct connection via threaded posts and internal threads inevitably requires prolonged rotation of one of the seamless steel pipes during the connection process. If the steel pipe is heavy or long, the connection process becomes time-consuming and laborious. Furthermore, the presence of the fan-shaped, barbed locking block also affects the disassembly of the steel pipe. Therefore, a pluggable seamless steel pipe is proposed to solve the problem of the existing seamless steel pipes being difficult to install and disassemble conveniently and stably.

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a pluggable seamless steel pipe, which solves the aforementioned problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pluggable seamless steel pipe, comprising a steel pipe one, a steel pipe two disposed on one side of the steel pipe one, a stabilizing mechanism disposed at the connection between the steel pipe one and the steel pipe two, a connecting groove opened on the side of the steel pipe two facing the steel pipe one, a connecting ring disposed in the inner cavity of the connecting groove, an L-shaped groove opened on the outer ring of the steel pipe two, a locking post disposed in the inner cavity of the L-shaped groove, a retaining groove opened on the outer ring of the steel pipe one, a baffle slidably disposed in the inner cavity of the retaining groove, an anti-detachment groove opened through the top of the baffle, a limit bolt disposed in the inner cavity of the anti-detachment groove, and a chamfered edge disposed on one side of the outer ring of the connecting ring.

[0009] Preferably, the connecting ring is fixedly connected to the steel pipe, and the limiting bolt penetrates to the inner wall of the retaining groove and the two are threadedly connected.

[0012] Preferably, a retaining ring is fixedly connected to the outer ring of the first steel pipe, a sealing ring is fixedly connected to the side of the retaining ring facing the stabilizing sleeve, and a sealing ring is provided at the contact point between the stabilizing sleeve and the second steel pipe.

[0013] Preferably, the outer ring of the stabilizing sleeve has a groove, and the inner cavity of the groove is rotatably connected to a handle. The joint between the handle and the groove is connected by two magnetic plates.

[0014] Preferably, both the inner walls of the retaining groove and the L-shaped slot are provided with limiting grooves, and the inner cavity of the limiting groove is slidably provided with a limiting block, which is fixedly connected to the baffle.

[0015] (III) Beneficial Effects

[0016] 1. This pluggable seamless steel pipe allows the connecting ring on steel pipe one to be inserted into the connecting groove inside steel pipe two with a chamfered fit. During the process, the locking pin is inserted into the L-shaped locking groove and rotated. Then, the baffle in the retaining groove moves into the L-shaped locking groove to limit the locking pin under the action of preventing disengagement. Finally, the limiting bolt is tightened to limit the baffle. Steel pipe one and steel pipe two can be connected without the need for time-consuming and laborious rotation of the steel pipe. Conversely, they can be disassembled. This solves the problem of the difficulty in convenient and stable installation and disassembly of existing seamless steel pipes.

[0017] 2. This pluggable seamless steel pipe, after steel pipe one and steel pipe two are initially connected by L-shaped groove, clamping post and other structures, the handle in the groove is turned to be perpendicular to the stabilizing sleeve. The handle drives the stabilizing sleeve to rotate, and then under the action of internal and external threads, the stabilizing sleeve is rotated and moved to the connection point of steel pipe one and steel pipe two. This further improves the stability of the seamless steel pipe connection. At the same time, in conjunction with the sealing ring on the side of the retaining ring and the sealing ring in the stabilizing sleeve, the sealing performance of the steel pipe connection is improved.

[0024] 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.

[0025] Example: Please refer to Figure 1-5A type of seamless steel pipe that can be plugged in includes a steel pipe 1, a steel pipe 2 on one side of the steel pipe 1, a stabilizing mechanism 3 at the connection between the steel pipe 1 and the steel pipe 2, a connecting groove 4 on the side of the steel pipe 2 facing the steel pipe 1, a connecting ring 5 in the inner cavity of the connecting groove 4, an L-shaped groove 6 on the outer ring of the steel pipe 2, a locking post 7 in the inner cavity of the L-shaped groove 6, a retaining groove 8 on the outer ring of the steel pipe 1, a baffle 9 slidably arranged in the inner cavity of the retaining groove 8, an anti-detachment groove 10 through the top of the baffle 9, a limit bolt 11 in the inner cavity of the anti-detachment groove 10, and a chamfer 14 on one side of the outer ring boundary of the connecting ring 5.

[0026] Furthermore, the connecting ring 5 is fixedly connected to the steel pipe 1, and the limiting bolt 11 penetrates to the inner wall of the retaining groove 8 and the two are threaded together.

[0027] Furthermore, the limiting bolt 11 does not penetrate into the inner cavity of the steel pipe 1, and the baffle 9 and the limiting bolt 11 are in a sliding connection.

[0028] Furthermore, the stabilizing mechanism 3 includes a stabilizing sleeve 301 disposed on the outer ring of the steel pipe 2. The inner ring of the stabilizing sleeve 301 is provided with an internal thread 302, and the outer rings of both the steel pipe 1 and the steel pipe 2 are provided with external threads 303 that are adapted to the internal thread 302.

[0029] Furthermore, a retaining ring 304 is fixedly connected to the outer ring of steel pipe 1, and a sealing ring 305 is fixedly connected to the side of retaining ring 304 facing the stabilizing sleeve 301. A sealing ring 309 is provided at the contact point between the stabilizing sleeve 301 and steel pipe 2.

[0030] Furthermore, the outer ring of the stabilizing sleeve 301 has a groove 306, and the inner cavity of the groove 306 is rotatably connected to a handle 307. The contact point between the handle 307 and the groove 306 is connected by two magnetic plates 308. After the steel pipe 1 and steel pipe 2 are initially connected by the L-shaped slot 6, the locking post 7, etc., the handle 307 in the groove 306 is turned to be perpendicular to the stabilizing sleeve 301. The handle 307 drives the stabilizing sleeve 301 to rotate. Then, under the action of the internal thread 302 and the external thread 303, the stabilizing sleeve 301 is rotated and moved to the connection point of steel pipe 1 and steel pipe 2. This further improves the stability of the seamless steel pipe connection. At the same time, it works with the sealing ring 305 on one side of the retaining ring 304 and the sealing ring 309 in the stabilizing sleeve 301 to improve the sealing performance of the steel pipe connection.

[0031] Furthermore, both the inner walls of the retaining groove 8 and the L-shaped slot 6 are provided with limiting grooves 12. The inner cavity of the limiting groove 12 is slidably provided with a limiting block 13. The limiting block 13 is fixedly connected to the baffle 9. When the baffle 9 in the moving retaining groove 8 limits the locking post 7, it cooperates with the limiting block 13 in the limiting groove 12 to improve the stability of the baffle 9, that is, to improve the firmness of limiting the locking post 7.

[0032] Working principle: When using this pluggable seamless steel pipe, the connecting ring 5 on steel pipe 1 is inserted into the connecting groove 4 inside steel pipe 2 with the help of chamfer 14. During the process, the locking post 7 is inserted into the L-shaped locking groove 6 and rotated. Then, the baffle 9 in the blocking groove 8 is moved into the L-shaped locking groove 6 under the action of anti-disengagement 10 to limit the locking post 7. Then, the limiting bolt 11 is tightened to limit the baffle 9. The connection between steel pipe 1 and steel pipe 2 can be achieved without the time-consuming and laborious rotation of the steel pipe. Conversely, it can be disassembled. This solves the problem of the difficulty in convenient and stable installation and disassembly of existing seamless steel pipes. When multiple seamless steel pipes need to be connected, the connecting groove 4 can be opened on the side of steel pipe 1 away from the connecting ring 5, and the connecting ring 5 can be fixed on the side of steel pipe 2 away from the connecting groove 4, thereby realizing the connection of multiple steel pipes 1 and steel pipe 2.
