Description

Technical Field

[0001] This utility model belongs to the technical field of pipe connection devices, and in particular relates to a pipe connection device for heating pipelines. Background Technology

[0002] Heating pipelines are piping systems used to transmit heating media to achieve heat energy delivery. Their function is to transport the heat generated by the heat source to the user end through the pipeline network to meet the needs of heating, domestic hot water or industrial heat. They are an important part of the centralized heating system. It is necessary to ensure that the medium is stable, efficient and safe during transmission. In actual installation, there is a need for segmented connection of pipelines. Connection devices can realize reliable connection between pipelines and prevent leakage of heating media.

[0003] However, existing pipe connection devices are not convenient for quick pipe connection during use, resulting in low installation efficiency, increased construction time and labor costs, and may delay heating supply, especially during emergency repairs or system expansion, affecting users' heating needs. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe connection device for heating pipelines. By setting up a quick-connect part, it solves the problem that existing pipe connection devices are not convenient for quick connection of pipes during use, resulting in low installation efficiency, increased construction time and labor costs, and may delay heating supply and affect users' heating needs, especially in emergency repairs or system expansion.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a pipe connection device for heating pipelines, including a first heating pipe and a second heating pipe disposed on the right side of the first heating pipe, and further including: a quick-connect part disposed on the first heating pipe and the second heating pipe; and a locking part disposed on the second heating pipe and the second locking part, wherein a plurality of locking parts are provided, and the plurality of locking parts are arranged in a circumferential array around the first heating pipe and the second heating pipe; wherein, the quick-connect part is used to quickly connect the first heating pipe and the second heating pipe, and the locking part is used to fix the first heating pipe and the second heating pipe together.

[0007] Furthermore, the quick-installation part includes a support assembly that is fitted onto heating pipe one and heating pipe two; and a sliding assembly that is mounted on the support assembly; wherein the support assembly is used for quick installation and the sliding assembly is used to provide elasticity.

[0008] Furthermore, the locking part includes a threaded assembly that passes through the first heating pipe and the second heating pipe; and a locking assembly that is mounted on the threaded assembly; wherein the locking assembly is used to lock the threaded assembly to prevent it from falling off.

[0009] Furthermore, the support assembly includes two semi-circular mounting rings disposed on the outer walls of heating pipe one and heating pipe two, the rear sides of the two semi-circular mounting rings being hinged together, and an L-shaped support plate being fixedly connected to the front outer wall of each of the two semi-circular mounting rings. A cylinder is fixedly connected to the front side of the outer L-shaped support plate, and a limiting rod passes through the cylinder. The limiting rod is slidably connected to the cylinder, and the rear side of the limiting rod passes through the two L-shaped support plates; wherein, the limiting rod is disposed at the central axis of the cylinder.

[0010] Furthermore, the sliding assembly includes a disc fixedly connected to the outer wall of the limiting rod, the disc being slidably connected to the cylinder, a handle being fixedly connected to the front extension of the limiting rod, and an elastic element being sleeved on the outer wall of the limiting rod; wherein, the disc is used to limit and guide the limiting rod.

[0011] Furthermore, the threaded assembly includes a bolt passing through heating pipe one and heating pipe two, a nut being threaded onto the outer wall of the bolt, and a hexagonal limiting plate being fixedly connected to the right side of the nut; wherein the hexagonal limiting plate is hollow.

[0012] Furthermore, the locking component includes several limiting grooves formed on the right side of the hexagonal limiting plate, with a locking block passing through two corresponding limiting grooves, and the locking block passing through a bolt; wherein, the locking block is normally straight, but is bent after insertion.

[0013] Furthermore, the elastic element includes a spring sleeved on the outer wall of the limiting rod, the rear side of the spring being fixedly connected to the disc, and the front side of the spring being fixedly connected to the cylinder; wherein, the spring is normally in a compressed state and has elastic force.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a quick-installation section, when the heating pipes need to be installed, two semi-circular installation rings can be placed on heating pipe one and heating pipe two. Then, pull the handle, which will cause the disc to move forward through the spring. During this process, the spring will be compressed, undergo elastic deformation, and generate elastic force, which will then cause the two L-shaped support plates to stick together. Then, release the handle, at which point the spring releases its elastic force, which acts on the limit rod through the disc, locking the two L-shaped support plates together. This completes the quick installation of heating pipe one and heating pipe two, which can significantly shorten the installation time, improve construction efficiency, and reduce labor costs. Especially in emergency repairs or system expansion, it can reduce heating delays and meet users' heating needs in a timely manner. Moreover, the simple connection process can reduce component wear, ensure the sealing and service life of the device, reduce the risk of pipe exposure, and improve the overall stability of the system.

[0016] 2. By setting a locking part, after installation, the bolts are passed through heating pipe one and heating pipe two, and then the nut is fixed on the bolt. The locking block is then passed through the bolt and through the two corresponding limiting grooves of the pipe to lock the nut, preventing it from falling off. This can firmly fix heating pipe one and heating pipe two, preventing the nut from falling off due to pipe vibration, medium pressure and other factors. This ensures a tight and stable connection at the pipe joint, prevents leakage of heating medium, effectively improves the safety and reliability of the heating pipeline system, and reduces the frequency and cost of later maintenance and repair.
