Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and specifically to an integrated pipeline connection device. Background Technology

[0002] Integrated piping is widely used in various industrial production, construction projects, and municipal facilities to transport fluids (such as liquids and gases). During the installation of integrated piping, two pipe bodies need to be connected to establish a connection between them.

[0003] However, the current method of connecting pipes is usually to use flange connections, which are fixed to the flange connection with bolts. During the connection process, multiple bolts need to be tightened one by one with a wrench, which is cumbersome. Moreover, when the flange is disassembled for maintenance later, the bolts need to be stored somewhere, which is very inconvenient and affects maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to design an integrated pipe connection device that can solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated pipe connection device includes a first pipe body and a second pipe body. The flanges of the first and second pipe bodies are respectively provided with a plurality of corresponding first and second connection holes. A limit ring is movably connected to the outer wall of the first pipe body. A limit rod corresponding to the first connection hole is provided on the side of the limit ring. A pull ring is provided on the outside of the second pipe body. An external thread is provided on the outer wall of the second pipe body. An internal thread connected to the external thread is provided on the inner wall of the pull ring. A nut and a locking ring are rotatably connected to the pull ring. A pull rod corresponding to the limit rod is provided on the side of the locking ring away from the nut. One end of the limit rod passes through the first and second connection holes sequentially and is detachably connected to one end of the pull rod.

[0007] Furthermore, the limiting ring is provided with a through hole for the first tube body to pass through.

[0008] Furthermore, the locking ring is provided with a circular hole that rotatably engages with the pull ring, and a collar is fixedly connected to the outer wall of the pull ring near the second connecting hole, with the pull ring located between the collar and the nut.

[0009] Furthermore, the distance between the collar and the nut is greater than the length of the pull ring.

[0010] Furthermore, the end of the limiting rod away from the limiting ring is provided with a groove, and the end of the pull rod away from the locking ring is provided with a protrusion that engages with the groove.

[0011] Furthermore, the inner wall of the groove away from the limiting ring is provided with a slot, and the side of the protrusion is provided with a locking block that engages with the slot.

[0012] Furthermore, both the slot and the block have interlocking triangular cross-sections.

[0013] The beneficial effects of this utility model are as follows:

[0014] After the limit rod and pull rod are detachably connected, turning the nut causes the pull ring to rotate. The pull ring then moves the pull rod through the locking ring, allowing the pull rod to pull the limit rod. The limit rod then moves the limit ring, which in turn pushes the flange of the first pipe body closer to the flange of the second pipe body, thus connecting the flanges of the first and second pipe bodies. This eliminates the need to tighten multiple bolts, making the operation simple. Furthermore, when disassembling the flange for maintenance, the removed limit ring and pull ring do not require storage, making maintenance convenient, simple, and efficient.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-3As shown, an integrated pipe connection device includes a first pipe body 1 and a second pipe body 2. The flanges of the first pipe body 1 and the second pipe body 2 are respectively provided with a plurality of corresponding first connecting holes 3 and second connecting holes 4. A limiting ring 5 is provided on the outside of the first pipe body 1, and the limiting ring 5 has a through hole 13 for the first pipe body 1 to pass through, allowing the limiting ring 5 to move freely on the outer wall of the first pipe body 1 and along the length direction of the first pipe body 1. A limiting rod 6 corresponding to the first connecting hole 3 is fixedly connected to the side of the limiting ring 5. A pull ring 7 is provided on the outside of the second pipe body 2. The outer wall of the second tube 2 is provided with an external thread 8, and the inner wall of the pull ring 7 is provided with an internal thread 9 that is threaded to the external thread 8. When the pull ring 7 is rotated, it can move along the length of the second tube 2. A nut 10 and a locking ring 11 are fixedly connected to the outer wall of the pull ring 7. By using a wrench to turn the nut 10, the pull ring 7 can be rotated. The locking ring 11 is provided with a round hole 14 that rotatably engages with the pull ring 7, allowing the pull ring 7 to rotate on the locking ring 11. The outer wall of the pull ring 7 near the second connecting hole 4 is fixedly connected to... A collar 15 is provided, and a pull ring 7 is located between the collar 15 and the nut 10, which limits the pull ring 7. A locking ring 11 has a pull rod 12 corresponding to the limiting rod 6 on the side away from the nut 10. The end of the limiting rod 6 away from the limiting ring 5 has a groove 16, and the end of the pull rod 12 away from the locking ring 11 has a protrusion 17 that engages with the groove 16, allowing for a detachable connection between the limiting rod 6 and the pull rod 12. After the protrusion 17 and the groove 16 engage, the pull rod 12 can pull the limiting rod 6. The inner wall of the groove 16 away from the limiting ring 5 is provided with… The groove 18 has a locking block 19 on its side that engages with the groove 18. The engagement of the groove 18 and the locking block 19 prevents the pull rod 12 from rotating, thereby improving the fixing effect between the two flanges. The cross-sections of the groove 18 and the locking block 19 are interlocking triangular structures. The engagement of the triangular inclined structure makes it easier for the groove 18 and the locking block 19 to engage. The distance between the collar 15 and the nut 10 is greater than the length of the pull ring 7, which increases the flexibility of the pull ring 7 and makes it easier for the protrusion 17 and the groove 16 to be engaged.

[0024] Working principle:

[0025] like Figure 2-4As shown, when using the pipe connection device, first align the flanges of the first pipe body 1 and the second pipe body 2. Then, push the limiting ring 5 to move freely on the outer wall of the first pipe body 1, allowing the end of the limiting rod 6 away from the limiting plate 5 to pass through the first connecting hole 3 and the second connecting hole 4 in sequence. Next, use a wrench to turn the nut 10, allowing the pull ring 7 to move on the second pipe body 2. After the pull ring 7 moves to the appropriate position, turn the locking ring 11 by hand to engage the locking block 19 with the locking groove 18. Then, use a wrench to turn the nut 10, allowing the pull ring 7 to move away from the limiting ring 5, and the pull ring 7 will pass through... The locking ring 11 drives the pull rod 12 to move. When the pull rod 12 moves, the locking block 19 and the locking groove 18 will engage. Then the pull rod 12 can pull the limiting rod 6 to move. The limiting rod 6 will drive the limiting ring 5 to move, so that the limiting ring 5 pushes the flange of the first pipe body 1 to move closer to the flange of the second pipe body 2, thereby connecting the flange of the first pipe body 1 and the flange of the second pipe body 2. It does not require tightening multiple bolts for fixation, which is simple to operate. In addition, when the flange is disassembled for maintenance in the later stage, the disassembled limiting ring 5 and pull ring 7 do not need to be stored anywhere, which is convenient and simple, and improves maintenance efficiency.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
