Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically a transmission pipeline for urban heating. Background Technology

[0002] As a core component of urban heating systems, heating pipe connections in current heating pipe connection devices (such as patent CN210128127 U) require more than 10 components, including an inner fixing sleeve, a turbine section, and a round pin, to fix and fine-tune the pipes. The second clamping mechanism adjusts the height through multiple mechanisms such as screws, sliders, and inclined planes. The excessive number of mechanical linkages and the complexity of the structure directly increase manufacturing costs and require high processing precision. Failure of any component (such as worm wear or gear meshing deviation) can lead to overall malfunction. The installation process requires repeated adjustments to each mechanism (such as alignment of guide rail rollers and calibration of inclined plane fit), which is time-consuming and labor-intensive. The difficulty is greatly increased, especially in confined spaces or when working at heights. For example, the inner fixing sleeve and the first frame are connected by a round pin. When disassembling, the meshing of the turbine section and the worm must be disengaged first, and then the locking screw must be removed. The steps are cumbersome and inconvenient for disassembling, replacing, and repairing the pipes.

[0003] Therefore, we propose a transmission pipeline for urban heating. Utility Model Content

[0004] The purpose of this utility model is to provide a transmission pipeline for urban heating to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transmission pipeline for urban heating, comprising a first pipeline, a second pipeline, and a pin; The first connecting ring is fixedly connected to the right end of the first pipe; The second connecting ring is fixedly connected to the left end of the second pipe; The L-shaped connecting plate is fixedly connected to the first connecting ring; Through holes are provided on the L-shaped connecting plate; The locking block is fixedly connected to the second connecting ring; The bayonet is located in the middle of the card block; Anti-slip texture is provided on the right half of the second connecting ring, and the left half of the first connecting ring is also provided with anti-slip texture; A sealing ring is fixedly installed on the left side of the second connecting ring; A sealing groove is located on the right side of the first connecting ring.

[0006] Preferably, the second connecting ring is also provided with an L-shaped connecting plate, and the first connecting ring and the second connecting ring are respectively provided with two sets of L-shaped connecting plates.

[0007] Preferably, the two sets of L-shaped connecting plates are arranged symmetrically about the central axis of the first connecting ring.

[0008] Preferably, the side of the L-shaped connecting plate near the through hole is set as a bevel.

[0009] Preferably, the pin engages with the through hole, and slots are provided at both ends of the pin surface.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Rotating the second connecting ring causes the locking block on the second connecting ring to engage the L-shaped connecting plate on the first connecting ring through a locking slot in its middle. Simultaneously, the locking block on the first connecting ring engages the L-shaped connecting plate on the second connecting ring through a locking slot in its middle, thus connecting and fixing the first and second connecting rings and completing the connection between the first and second pipes. Locking can be achieved simply by rotating the pipe, eliminating the need for bolt tightening and welding, making pipe connection quick and particularly suitable for space-constrained or high-altitude operations. After rotation, the locking block and the L-shaped connecting plate engage, resisting axial pull-out and radial displacement. The locking block is limited by a pin passing through a through hole, making it less prone to loosening under vibration. Furthermore, after removing the pin, the second connecting ring can be rotated in the opposite direction to disassemble the first and second pipes without welding or thread wear. The components can be disassembled and reassembled multiple times, facilitating pipe replacement and maintenance. Attached Figure Description

[0013] 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.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a transmission pipeline for urban heating, including a first pipeline 1, a second pipeline 2 and a pin 9, a first connecting ring 3 fixedly connected to the right end of the first pipeline 1, a second connecting ring 4 fixedly connected to the left end of the second pipeline 2, an L-shaped connecting plate 5 fixedly connected to the first connecting ring 3, a through hole 51 provided on the L-shaped connecting plate 5, a locking block 6 fixedly connected to the second connecting ring 4, a locking opening 7 provided in the middle of the locking block 6, anti-slip texture 8 provided on the right half of the second connecting ring 4, and the left half of the first connecting ring 3 also provided with anti-slip texture 8, a sealing ring 11 fixedly installed on the left side of the second connecting ring 4, and a sealing groove 12 provided on the right side of the first connecting ring 3; Connect and fix the first pipe 1 and the second pipe 2. Install a sealing ring that mates with the sealing groove 12 into the sealing groove 12. Move the second pipe 2 so that the second connecting ring 4 at the left end of the second pipe 2 moves closer to the first connecting ring 3 at the right end of the first pipe 1. The sealing ring 11 on the left side of the second connecting ring 4 is installed into the sealing groove 12. At the same time, the locking block 6 on the second connecting ring 4 moves to one end of the L-shaped connecting plate 5 on the first connecting ring 3. By using a tool (such as a chain wrench) wrapped around the anti-slip texture 8 of the second connecting ring 4 and rotating the second connecting ring 4, the locking block 6 on the second connecting ring 4 locks the L-shaped connecting plate 5 on the first connecting ring 3 through the locking slot 7 in its middle. At the same time, the locking block 6 on the first connecting ring 3 locks the L-shaped connecting plate 5 on the second connecting ring 4 through the locking slot 7 in its middle. The L-shaped connecting plate 5 is used to connect and fix the first connecting ring 3 and the second connecting ring 4, thus completing the connection between the first pipe 1 and the second pipe 2. After the connection between the first pipe 1 and the second pipe 2 is completed, the pin 9 is passed through the through hole 51, and the retaining ring is installed in the retaining groove 10 set at both ends of the through hole. The retaining block 6 is limited by the pin 9, so that the connection between the first pipe 1 and the second pipe 2 is stable. Locking can be completed by simply rotating the pipe, eliminating the need for bolt tightening, welding and other processes. It is especially suitable for space-constrained or high-altitude operation scenarios. After rotation, the retaining block 6 and the L-shaped connecting plate 5 form an engagement, resisting axial pull-out and radial displacement, which is more reliable than a simple clamp. The retaining block 6 is limited by the pin 9, and it is not easy to loosen in a vibration environment. After removing the pin 9, the second connecting ring 4 is rotated in the opposite direction to complete the disassembly of the first pipe 1 and the second pipe 2. There is no welding or thread wear. The components can be disassembled and assembled multiple times, which is convenient for pipe replacement and maintenance.

[0015] Reference embodiment: The second connecting ring 4 is also provided with an L-shaped connecting plate 5. The first connecting ring 3 and the second connecting ring 4 are respectively provided with two sets of L-shaped connecting plates 5. The two sets of L-shaped connecting plates 5 are symmetrically arranged about the central axis of the first connecting ring 3. The first connecting ring 3 and the second connecting ring 4 are respectively provided with two sets of locking blocks 6. The two sets of locking blocks 6 are symmetrically arranged about the axis. Rotating the first pipe 1 and the second pipe 2 causes the locking blocks 6 to lock the L-shaped connecting plates, thus completing the connection and fixation of the first pipe 1 and the second pipe 2.

[0016] The side of the L-shaped connecting plate 5 near the through hole 51 is set as an inclined surface. When the second connecting ring 4 drives the locking block 6 to rotate and lock the L-shaped connecting plate 5, the locking block 6 cooperates with the inclined surface to lock the L-shaped connecting plate 5, thereby connecting and fixing the first connecting pipe 1 and the second connecting pipe 2.

[0017] Reference embodiment: The pin 9 is engaged with the through hole 51. Both ends of the pin 9 are provided with slots 10. After the first pipe 1 and the second pipe 2 are connected, the pin 9 passes through the through hole. A retaining spring is installed in the slot 10 to limit and fix the pin 9, thereby limiting the retaining block 6 and making the connection between the first connecting pipe 1 and the second connecting pipe 2 stable.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
