Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, and specifically relates to a pipeline connection structure. Background Technique

[0002] The function of a pipeline is to transport liquid or gas. In pipelines, due to the limitation of pipeline length, the convenience of installation and disassembly, or considerations of pipeline materials, connections between pipelines are inevitable, and the connection joints at pipeline connection points are of various forms.

[0003] Chinese Patent Publication No. CN216201474U discloses a pipeline connection structure. This pipeline connection structure stably docks the connection head to the connection sleeve through a chute and a locking groove, and can also achieve the function of quick installation and disassembly. The process is fast and simple, effectively reducing the labor force of workers. Moreover, through a sealing ring and a sliding ring, the docking process is locked, and the sealed and docked pipelines improve safety performance. It can also enable the temperature derived from real-time monitoring by a thermometer to more accurately understand the state of the gas in the pipeline.

[0004] However, it has the following disadvantages: During the connection process of this device, mainly a single connection head is connected to a single sealing ring to achieve the sealing between pipelines. Since only a single connection head and a single sealing ring are relied on for sealing, when the single sealing ring has cracks or is damaged, leakage is likely to occur, reducing the safety of the device.

[0005] Therefore, a pipeline connection structure is proposed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0034] Specifically, as Figures 1-3 shown, there are two pipelines 1. Connecting piece two 102 is fixedly installed at one end of one side of pipeline 1, and connecting piece two 102 is fixedly connected to the side of connection ring 204.

[0035] In this embodiment: Through the cooperation of the provided connection ring 204 and connection groove 201, the device is preliminarily connected.

[0036] Specifically, as Figure 3 shown, sealing frame one 202 is fixedly installed on the inner wall of connection groove 201. Sealing frame two 203 is fixedly installed on the inner and outer walls of sealing frame one 202 respectively. Sealing groove one 205 and two sealing grooves two 206 are opened on the side of connection ring 204.

The inner and outer walls of sealing frame one 202 and the inner and outer walls of two sealing frames two 203 are slidably connected to the inner walls of sealing groove one 205 and two sealing grooves two 206 respectively. The sides of sealing frame one 202 and two sealing frames two 203 are respectively abutted against the sides of sealing pads 207.

[0037] In this embodiment: Through the sliding connection of the inner and outer walls of sealing frame one 202 and the inner and outer walls of two sealing frames two 203 with the inner walls of sealing groove one 205 and two sealing grooves two 206 respectively and the setting of sealing pads 207, the device is sealed in three ways, ensuring the device is safer.

[0038] Specifically, as Figures 1-6As shown, on the outer wall of one end of the second connecting member 102, a second fixing frame 302 is fixedly installed. The side surface of the first fixing frame 301 is slidably connected to the side surface of the second fixing frame 302. On the outer walls of the second fixing frame 302 and the first fixing frame 301, a plurality of connecting plates 303 and a plurality of elastic plates 304 are respectively fixedly installed. On the side surfaces of the plurality of connecting plates 303, two limiting grooves 305 are respectively formed. On the side surfaces of the plurality of elastic plates 304, two limiting blocks 306 are respectively fixedly installed. The side surfaces of the plurality of limiting blocks 306 are respectively slidably connected to the inner walls of the plurality of limiting grooves 305.

[0039] In this embodiment: By providing the limiting blocks 306 and the limiting grooves 305, it is not easy to have an offset when the elastic plate 304 is connected to the connecting plate 303, improving the installation accuracy.

[0040] Specifically, as Figures 4-6 shown, on the outer walls of the plurality of connecting plates 303 and the outer walls of the plurality of elastic plates 304, a plurality of card frames 307 are respectively clamped. On the left and right side surfaces of the plurality of card frames 307, L-shaped plates 308 are respectively fixedly installed.

[0041] In this embodiment: By providing the card frames 307, the connecting plates 303 and the elastic plates 304 are fixed.

[0042] Specifically, as Figures 4-6 shown, on the side surfaces of the plurality of fixing blocks 310, through grooves 311 are respectively formed. The outer walls of the L-shaped plates 308 are slidably connected to the inner walls of the through grooves 311. A moving plate 312 is slidably connected to the inner wall of the through groove 311.

[0046] The specific solution of this scheme is as follows: By inserting the connecting ring 204 into the connecting groove 201, at this time, the first sealing frame 202 and the two second sealing frames 203 are respectively inserted into the first sealing groove 205 and the two second sealing grooves 206 to abut against the sealing gasket 207, forming a three - layer sealing structure to seal the device. When one of the sealing gaskets 207 has cracks or is damaged, the other two sealing structures can still provide a good sealing effect on the device, ensuring that the device will not leak and improving the safety of the device. Connect the elastic plate 304 with the connecting plate 303. At this time, the limiting block 306 moves in the limiting groove 305 for limiting, and the clamping frame 307 fixes the elastic plate 304 and the connecting plate 303. Then rotate the handle 316 to drive the moving plate 312 and the clamping column 313 to move upward. Drive the L - shaped plate 308 to move into the groove body 311 through the clamping frame 307. Rotate the handle 316 to drive the moving plate 312 and the clamping column 313 to move downward. The clamping column 313 moves into the fixing hole 309 and the clamping hole 314 to fix the L - shaped plate 308, and further fix the clamping frame 307, so that the device is fixed. The device is not easy to loosen and is relatively convenient to install, with a high installation efficiency.
