A pipe joint

Abstract

This utility model belongs to the field of pipe connection technology, specifically a pipe joint. This process involves setting screws, a limiting frame, a magnetic rod, and a slot. First, a flange is welded to the outside of the pipe. The limiting frame is pulled down from the outside of the limiting rod, and the screws are tightened against the flange on the outside of the pipe. Then, the limiting frame is tightened against the flange on the outside of the pipe, allowing the limiting rod to re-insert into the inside of the limiting frame. Multiple screws are rotated to screw into the flange on the outside of the pipe and the inside of the limiting frame. The limiting frame is tightened against the flange on the outside of the pipe for reinforcement. Then, the spring is released, allowing the magnetic rod to be inserted into the slot inside the polygonal frame for restriction. When the device vibrates, the magnetic rod slides back and forth inside the polygonal frame, thereby restricting the position of the polygonal frame and the connection between the screws and the pipe. The device can also be disassembled after use without using hydraulic pliers to squeeze the pipe and pipe joint, making the device less prone to damage and improving its stability.

Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, specifically a pipe joint. Background Technology

[0002] Pipe connections have always been a major challenge during installation. To make the installation more stable, some existing installation methods use hydraulic clamps to tighten the pipe joints and pipe connections, thus making the connection more secure.

[0003] However, if this installation method is not performed correctly, the connection between the pipe joint and the pipe can easily be damaged, resulting in the entire pipe and pipe joint being scrapped. It is necessary to cut it off and reconnect a new pipe and replace the pipe joint. Furthermore, it is difficult to remove and reuse the pipe joint after use, which can easily increase the installation cost. Therefore, a pipe joint is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A pipe joint of this utility model includes a pipe joint body, a gear ring rotatably connected to the outside of the pipe joint body, a polygonal frame fixedly connected to the outside of the gear ring, a first gear meshing with the outside of the gear ring, the first gear being rotatably connected to the pipe joint body, a screw fixedly connected to the outside of the first gear, a flange rotatably connected to the outside of the screw, the flange being fixedly connected to the pipe joint body, a limit rod fixedly connected to the outside of the flange, a limit frame slidably connected to the outside of the limit rod, the limit frame cooperating with the screw, a spring fixedly connected to the outside of the pipe joint body, a movable frame fixedly connected to one end of the spring, a magnetic rod fixedly connected to the outside of the movable frame, a slot being formed on the surface of the polygonal frame, and the magnetic rod and the slot being matched... This process involves setting up screws, a limiting frame, a magnetic rod, and a slot. First, a flange is welded to the outside of the pipe. The limiting frame is then pulled down from the outside of the limiting rod. The screws are then pressed tightly against the flange on the outside of the pipe. Next, the limiting frame is pressed tightly against the flange on the outside of the pipe, allowing the limiting rod to be inserted back into the inside of the limiting frame. Multiple screws are then turned to screw them into the flange on the outside of the pipe and the inside of the limiting frame. The limiting frame is then pressed tightly against the flange on the outside of the pipe for reinforcement. Finally, the spring is released, allowing the magnetic rod to be inserted into the slot inside the polygonal frame for restriction. When the device vibrates, the magnetic rod slides back and forth inside the polygonal frame, thereby restricting the position of the polygonal frame and the connection between the screws and the pipe. The device can also be disassembled after use without using hydraulic pliers to squeeze the pipe and pipe joints, making the device less prone to damage and improving its stability.

[0006] Preferably, a movable screw is rotatably connected to the outer side of the pipe joint body, a locking block is threadedly connected to the outer side of the movable screw, a limiting rod is slidably connected to the inner side of the locking block, the limiting rod is fixedly connected to the pipe joint body, and a locking groove is provided on the inner side of the limiting frame. This step, by setting the movable screw, locking block, limiting rod, and locking groove, ensures that after the limiting frame is pressed against the flange on the outer side of the pipe, rotating the movable screw causes the locking block to move, so that one end of the locking block inserts into the inner side of the locking groove, thereby further restricting the position of the limiting frame, making its restriction on the screw more stable, and improving the stability of the device connection.

[0007] Preferably, a second gear is fixedly connected to the outer side of the movable screw, and a toothed plate meshes with the outer side of the second gear. The toothed plate is slidably connected to the pipe joint body, and the toothed plate is fixedly connected to the movable frame. This step, by setting the second gear and the toothed plate, allows the movable frame to move synchronously, which in turn drives the toothed plate. The toothed plate drives the second gear to rotate, which in turn drives the movable screw to rotate, allowing multiple movable screws to rotate synchronously, thus improving the ease of use of the device.

[0008] Preferably, a limiting plate is fixedly connected to the outside of the movable screw, and the limiting plate and the locking block are used in conjunction. This step, by setting the limiting plate, allows the locking block to be blocked and restricted when it moves to the maximum position, making it difficult for the locking block to separate from the movable screw, thus improving the stability of the device.

[0009] Preferably, a magnetic plate is fixedly connected to the inner side of the pipe joint body, and a sealing ring is fixedly connected to the outer side of the magnetic plate. This step, by setting the magnetic plate and the sealing ring, allows the pipe joint body to be attracted to the outside of the pipe when connected to the pipe, thereby making the connection between the pipe joint body and the pipe more stable. The sealing ring is also used to seal the connection between the pipe and the pipe joint body, thereby improving the sealing performance of the device.

[0010] Preferably, a connecting plate is fixedly connected to the outer side of the limiting frame, and a connecting screw is threadedly connected to the inner side of the connecting plate. This step, by setting the connecting plate and the connecting screw, allows the limiting frame to be connected by screwing the connecting screw into the inner side of the connecting plate after it is fitted onto the outside of the pipe. This makes it easier to align the pipe and the pipe joint body when connecting them, thus improving the convenience of device connection.

[0011] The advantages of this utility model are: 1. This utility model, by setting screws, a limiting frame, a magnetic rod, and a slot, first welds a flange to the outside of the pipe, pulls the limiting frame down from the outside of the limiting rod, and then attaches the screw to the flange on the outside of the pipe. Next, the limiting frame is then attached to the flange on the outside of the pipe, allowing the limiting rod to be inserted back into the inside of the limiting frame. Multiple screws are rotated to screw into the flange on the outside of the pipe and the inside of the limiting frame, reinforcing the flange by the limiting frame. Then, the spring is released, allowing the magnetic rod to be inserted into the slot inside the polygonal frame for restriction. When the device vibrates, the magnetic rod slides back and forth inside the polygonal frame, thereby restricting the position of the polygonal frame and the connection between the screw and the pipe. The device can also be disassembled after use without using hydraulic pliers to squeeze the pipe and pipe joints, making the device less prone to damage and improving its stability. 2. This utility model, by setting a movable screw, a locking block, a limiting rod, and a locking groove, allows the limiting frame to be tightly attached to the flange on the outside of the pipe. By rotating the movable screw, the locking block is moved, causing one end of the locking block to insert into the inner side of the locking groove, thereby further restricting the position of the limiting frame, making its restriction of the screw more stable, and improving the stability of the device connection.

[0015] 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 scope of protection of the present utility model.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1 to 5 As shown, a pipe fitting includes a pipe fitting body 1. A gear ring 2 is rotatably connected to the outside of the pipe fitting body 1. A polygonal frame 3 is fixedly connected to the outside of the gear ring 2. A first gear 4 meshes with the outside of the gear ring 2, and the first gear 4 is rotatably connected to the pipe fitting body 1. A screw 5 is fixedly connected to the outside of the first gear 4. A flange 6 is rotatably connected to the outside of the screw 5, and the flange 6 is fixedly connected to the pipe fitting body 1. A limit rod 7 is fixedly connected to the outside of the flange 6. A limit frame 9 is slidably connected to the outside of the limit rod 7. The limit frame 9 and the screw 5 cooperate. A spring 10 is fixedly connected to the outside of the pipe fitting body 1. A movable frame 11 is fixedly connected to one end of the spring 10. A magnetic rod 12 is fixedly connected to the outside of the movable frame 11. A slot 13 is formed on the surface of the polygonal frame 3, and the magnetic rod 12 and the slot 13 cooperate. This step involves setting... The device consists of screw 5, limit frame 9, magnetic rod 12, and slot 13. First, weld a flange 6 to the outside of the pipe. Pull the limit frame 9 down from the outside of the limit rod 7. Tighten the screw 5 against the flange 6 on the outside of the pipe. Then, tighten the limit frame 9 against the flange 6 on the outside of the pipe, and insert the limit rod 7 back into the inside of the limit frame 9. Rotate the screws 5 so that they are screwed into the flange 6 on the outside of the pipe and the inside of the limit frame 9. The limit frame 9 is tightened against the flange 6 on the outside of the pipe for reinforcement. Then, release the spring 10 so that the magnetic rod 12 is inserted into the slot 13 inside the polygonal frame 3 for restriction. When the device vibrates, the magnetic rod 12 slides back and forth inside the polygonal frame 3, thereby restricting the position of the polygonal frame 3 and the connection between the screw 5 and the pipe. The device can also be disassembled after use without using hydraulic pliers to squeeze the pipe and pipe joints, making the device less prone to damage and improving the stability of the device.

[0018] Furthermore, such as Figure 1 and Figure 5As shown, a movable screw 14 is rotatably connected to the outer side of the pipe joint body 1. A locking block 15 is threadedly connected to the outer side of the movable screw 14. A limiting rod 16 is slidably connected to the inner side of the locking block 15. The limiting rod 16 is fixedly connected to the pipe joint body 1. A slot 17 is provided on the inner side of the limiting frame 9. In this step, by setting the movable screw 14, locking block 15, limiting rod 16 and slot 17, the limiting frame 9 is made to fit tightly against the flange 6 on the outer side of the pipe. By rotating the movable screw 14, the locking block 15 is moved, so that one end of the locking block 15 is inserted into the inner side of the slot 17, thereby further restricting the position of the limiting frame 9, making its restriction on the screw 5 more stable, and improving the stability of the device connection.

[0019] Furthermore, such as Figure 1 As shown, a second gear 18 is fixedly connected to the outer side of the movable screw 14, and a toothed plate 19 meshes with the outer side of the second gear 18. The toothed plate 19 is slidably connected to the pipe joint body 1, and the toothed plate 19 is fixedly connected to the movable frame 11. This step, by setting the second gear 18 and the toothed plate 19, allows the movable frame 11 to move synchronously, thereby driving the toothed plate 19. The toothed plate 19 then drives the second gear 18 to rotate, which in turn drives the movable screw 14 to rotate. This allows multiple movable screws 14 to rotate synchronously, improving the ease of use of the device.

[0020] Furthermore, such as Figure 1 As shown, a limiting plate 20 is fixedly connected to the outside of the movable screw 14. The limiting plate 20 and the locking block 15 are used in conjunction. By setting the limiting plate 20, when the locking block 15 moves to the maximum position, it can be blocked and restricted by the limiting plate 20, making it difficult for the locking block 15 to separate from the movable screw 14, thus improving the stability of the device.

[0021] Furthermore, such as Figure 2 As shown, a magnetic plate 21 is fixedly connected to the inner side of the pipe joint body 1, and a sealing ring 22 is fixedly connected to the outer side of the magnetic plate 21. This step, by setting the magnetic plate 21 and the sealing ring 22, allows the pipe joint body 1 to be attracted to the outside of the pipe when connected to the pipe, thereby making the connection between the pipe joint body 1 and the pipe more stable. The sealing ring 22 is also used to seal the connection between the pipe and the pipe joint body 1, thereby improving the sealing performance of the device.

[0022] Furthermore, such as Figure 2As shown, a connecting plate 23 is fixedly connected to the outer side of the limiting frame 9, and a connecting screw 24 is threadedly connected to the inner side of the connecting plate 23. This step, by setting the connecting plate 23 and the connecting screw 24, allows the limiting frame 9 to be connected by screwing the connecting screw 24 into the inner side of the connecting plate 23 after it is fitted onto the outside of the pipe. This makes it easier for the limiting frame 9 to be fitted onto the outside of the pipe, and when the pipe and the pipe joint body 1 are connected, the limiting frame 9 can be connected to the limiting rod 7, thereby facilitating the alignment and connection of the pipe and the pipe joint body 1 and improving the convenience of device connection.

[0023] Working principle: First, weld a flange 6 to the outside of the pipe. Pull the limiting frame 9 down from the outside of the limiting rod 7. Tighten the screw 5 to the flange 6 on the outside of the pipe. Then, tighten the limiting frame 9 to the flange 6 on the outside of the pipe, and insert the limiting rod 7 back into the inside of the limiting frame 9. Rotate the polygonal frame 3, which drives the gear ring 2 to rotate. The gear ring 2 drives multiple first gears 4 to rotate, which in turn drives multiple screws 5 to rotate, causing them to screw into the flange 6 on the outside of the pipe and the inside of the limiting frame 9. The limiting frame 9 is then tightened to the flange 6 on the outside of the pipe for reinforcement. Then, release the spring 10, which drives the movable frame 11 to move. The movable frame 11 then drives the magnetic rod 12 to insert into the inside of the polygonal frame 3. The position of the slot 13 is restricted. At the same time, the movable frame 11 drives the toothed plate 19 to rotate, the toothed plate 19 drives the second gear 18 to rotate, the second gear 18 drives the movable screw 14 to rotate, and the movable screw 14 drives the locking block 15 to insert into the inner side of the locking slot 17, thereby further fixing the position of the limiting frame 9. When the device vibrates, the vibration may cause the spring 10 to shake to a certain extent, causing the magnetic rod 12 to slide back and forth inside the polygonal frame 3. The magnetic rod 12 is attracted to the inner side of the polygonal frame 3 and is set with a certain length, making it difficult for it to completely move out of the inner side of the polygonal frame 3, thereby restricting the position of the polygonal frame 3, and thus restricting the connection between the screw 5 and the pipe.
