Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a pipeline connection component and a pipeline. Background Technology

[0002] A pipeline is a channel used to transport various substances such as gases, liquids, and powders. It can be made of a variety of materials, including metals, plastics, and composite materials. Pipelines made of different materials have different characteristics and applications. Metal pipes usually have high strength and the ability to withstand high temperatures and pressures, making them suitable for some harsh environments in the industrial field. Plastic pipes, on the other hand, have the advantages of being lightweight, corrosion-resistant, and easy to install, and are widely used in building water supply and drainage and municipal engineering.

[0003] A search revealed Chinese Patent Publication No. CN206738771U, which discloses a pipe connection assembly and a pipe connection structure. In the pipe connection assembly, two fittings are respectively fitted onto both ends of a pipe fitting. Within the pipe fitting, a connecting cylinder has a recessed center forming a connecting platform. The connecting cylinder has a sealing groove and a through hole at its edge. The fittings have threaded holes on the side of the sleeve. In the pipe connection structure, two sections of pipe to be connected are inserted into the connecting cylinder. The pipes to be connected are sealed to the connecting cylinder by a sealing ring. Bolts pass through the threaded hole and the through hole in sequence and are pressed together with the pipes to be connected. This utility model provides strong sealing performance and easy assembly. While flange connections offer simple manufacturing processes, save on raw materials, and are lightweight, providing excellent protection for pipelines, existing flange connections rely heavily on bolts for fixing. This design makes on-site installation and subsequent maintenance quite complex, time-consuming, and labor-intensive. Although traditional welding connections can overcome the problems associated with flange connections to some extent, welding itself has many limitations. Welding quality is greatly affected by the skill level of the workers, and potential safety hazards may be introduced during the welding process, as well as damage caused by welding spatter. These issues, to varying degrees, restrict the advancement of traditional pipeline connection technology to a higher level. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pipe connection component and a pipe, aiming to improve the problems of high construction difficulty and long time consumption in the operation process of the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe connection assembly and a pipe, comprising a circular pipe, wherein a semi-shell is installed at both the front and rear ends of the outer wall of the circular pipe, and a fixed semi-circular ring is provided at both the front and rear ends of the left side of the semi-shell. Multiple first clamping plates are fixedly connected at equal intervals to the front side of the rear fixed semi-circular ring, and multiple second clamping plates are fixedly connected at equal intervals to the rear side of the front fixed semi-circular ring. A clamping block is fixedly connected to one side of each of the first and second clamping plates, and the clamping block engages with one side of the semi-shell. One end of the first clamping plate is fixedly connected to the second clamping plate via a spring. The middle of the first clamping plate is rotatably connected to the second clamping plate via a rotating short rod. Limiting baffles are fixedly connected to the opposite sides of the two semi-shells. Multiple positioning pins are installed at equal intervals in the middle of the semi-shell. The top center of the fixed semi-circular ring is fixedly connected via a connecting flexible rod, and a pulley is slidably connected to the middle of the connecting flexible rod. A warning mechanism is installed at the bottom of the semi-shell, and the warning mechanism is used to alert of liquid leakage in the pipe.

[0006] The above technical solution involves first installing two semi-shells at the connection of the circular pipe and fixing them with positioning pins. Then, the pulley is rotated and the connecting rod is retracted, causing the two clamping plates to rotate through the short rod. The spring retracts, and the clamping blocks separate. The mechanism is placed on the left side of the semi-shell and a limit stop is installed to ensure stability. Then, the right-angle rod is rotated in the opposite direction, causing the spring to rebound and push the clamping plates and clamping blocks to tightly engage with the semi-shell. This simplifies the pipe connection, reduces the construction difficulty, and improves efficiency.

[0007] As a further description of the above technical solution:

[0008] The warning mechanism includes a housing, which is installed at the bottom center of the semi-shell. Two male buckles are fixedly connected to the front and rear sides of the top of the housing, and two female buckles are fixedly connected to the bottom of the two semi-shells on opposite sides. The male buckles engage with the female buckles. A fixed round rod is fixedly connected to the middle of the housing, and a rotating ring is rotatably connected to the middle of the fixed round rod. A water inlet pipe is fixedly connected to the left side of the rotating ring, and a connecting light rod is fixedly connected to the bottom of the rotating ring. A ball is fixedly connected to the bottom of the connecting light rod.

[0009] The above technical solution works as follows: when a leak occurs, liquid drips from the bottom of the semi-shell into the water inlet pipe. After accumulation, the water inlet pipe rotates, triggering the rotating ring to make the ball hit the box and produce a sound, prompting the staff to carry out maintenance and extending the service life of the device.

[0010] As a further description of the above technical solution:

[0011] A protective sleeve is provided on the outside of the spring, and a fixing ring is installed in the middle of the outer wall of the protective sleeve.

[0012] The above technical solution prevents the spring 22 from being damaged by external factors through the cooperation of the protective sleeve and the fixing ring.

[0013] As a further description of the above technical solution:

[0014] Two connecting plates are fixedly connected to the upper and lower left ends of the fixed semicircular ring. Folding plates are rotatably connected to the adjacent left sides of the two connecting plates. The two folding plates are rotatably connected by a rotating short column.

[0015] With the above technical solution: when the device is not in use, the connecting plate will unfold through the folding plate, through which the device can be placed on a flat surface.

[0016] As a further description of the above technical solution:

[0017] Each of the two fixed semicircular rings has a handle installed on the left side away from each other, and the upper and lower ends of the handles are threaded with a second screw.

[0018] With the above technical solution, when it is necessary to move this device, it can be moved by the handle installed by the second screw.

[0019] As a further description of the above technical solution:

[0020] Two square plates are fixedly connected to the top of each of the two semi-shells on opposite sides, and the upper and lower ends of each square plate are threaded with a first screw.

[0021] The above technical solution allows the semi-shell to fit more tightly by installing the first screw and the square plate.

[0022] As a further description of the above technical solution:

[0023] A circular sleeve is rotatably connected to the top of the pulley, and a right-angle rod is installed on the top of the circular sleeve.

[0024] The above technical solution allows the right-angle rod to facilitate the rotation of the pulley, and the circular sleeve is installed to prevent it from slipping out of your hand during rotation.

[0025] As a further description of the above technical solution:

[0026] An annular groove is provided in the middle of the semi-shell, and an elastic sealing ring is provided inside the annular groove.

[0027] The above technical solution, namely the embedding of an elastic sealing ring, improves the sealing performance of the connection.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the two half-shells are first installed at the connection point and fixed with positioning pins. Then, the right-angle rod is rotated, and the connecting flexible rod is retracted, which causes the first clamping plate and the second clamping plate to be compressed by spring compression. They are then locked onto the half-shells and the position is determined by the limiting baffle. Then, the right-angle rod is rotated in the opposite direction, so that the other end of the first clamping plate and the second clamping plate will compress the half-shells. This simplifies the pipe connection process, reduces construction difficulty and time consumption, and improves work efficiency.

[0030] 2. In this utility model, when there is a leak at the connection, the liquid will flow down from the bottom of the semi-shell and drip into the water inlet pipe. When a certain amount is accumulated, the water inlet pipe will rotate and descend, the rotating ring will rotate and the ball will hit the box, making a sound, thereby prompting the staff to perform maintenance at this point and improving the service life of this device.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a pipe connection assembly and a pipe, including a circular pipe 1. Half-shells 4 are installed at both the front and rear ends of the outer wall of the circular pipe 1. Fixed semi-circular rings 11 are provided at the front and rear ends of the left side of each half-shell 4 to facilitate the installation of subsequent devices. Multiple first clamping plates 14 are equidistantly fixed to the front side of the rear fixed semi-circular rings 11, and multiple second clamping plates 20 are equidistantly fixed to the rear side of the front fixed semi-circular rings 11. Clamping blocks 21 are fixedly connected to one side of each of the first clamping plates 14 and second clamping plates 20, and the clamping blocks 21 engage with one side of each half-shell 4. One end of each first clamping plate 14 is fixedly connected to the second clamping plate 20 via a spring 22. The installation of the spring 22 allows the first clamping plate 14 and the second clamping plate 20 to be contracted or expanded. The middle of each first clamping plate 14 is rotatably connected to the second clamping plate 20 via a rotating short rod 23. The two half-shells 4 are spaced apart. Each side is fixedly connected with a limit baffle 26. Multiple positioning pins 3 are equidistantly installed in the middle of the half-shell 4 to determine and fix the position of the half-shell 4. The top center of the fixed semi-circular ring 11 is fixedly connected by a connecting flexible rod 7. A pulley 10 is slidably connected in the middle of the connecting flexible rod 7. A warning mechanism 2 is installed at the bottom of the half-shell 4 to alert the leakage of liquid in the pipeline. A protective sleeve 13 is provided on the outside of the spring 22. A fixed circular ring 12 is installed in the middle of the outer wall of the protective sleeve 13 to protect the spring 22 from damage. Two square plates 5 are fixedly connected to the top of the two half-shells 4 on opposite sides. The upper and lower ends of the square plates 5 are threaded with a first screw 6. A circular sleeve 9 is rotatably connected to the top of the pulley 10. A right-angle rod 8 is installed on the top of the circular sleeve 9. An annular groove 25 is opened in the middle of the half-shell 4. An elastic sealing ring 24 is provided inside the annular groove 25 to make it seal more tightly.

[0040] Specifically, firstly, the two half-shells 4 are installed at the connection point of the circular pipe 1; multiple locating pins 3 are used for positioning and fixing to ensure they are firmly fixed together; next, the right-angle rod 8 is driven by rotating the circular sleeve 9, causing the pulley 10 to start rotating. As the pulley 10 rotates, the connecting flexible rod 7 is gradually retracted. Through this retraction action, the second clamping plate 20 and the first clamping plate 14 will rotate by rotating the short rod 23; at this time, the spring 22 will retract accordingly, and the clamping blocks 21, which are fixedly connected to the first clamping plate 14 and the second clamping plate 20 respectively, will gradually move away from each other; after completing the above steps, the entire mechanism is placed on the left side of the half-shell 4; to ensure accurate engagement of the mechanism, a limiting stop 26 is installed to ensure accurate engagement. The springs 22 are properly engaged on the outside of the half-shell 4. Next, the right-angle rod 8 is rotated in the opposite direction, causing the multiple springs 22 to rebound. The rebound action of the springs 22 will quickly push the first clamping plate 14 and the second clamping plate 20, so that the clamping blocks 21 at their other ends are tightly engaged with the half-shell 4. An annular groove 25 is opened in the middle of the half-shell 4, and an elastic sealing ring 24 is embedded in it, which not only improves the sealing performance of the connection, but also reduces the difficulty and time consumption of construction. In this way, the work efficiency is improved, making the entire pipeline connection process more efficient and reliable. A protective sleeve 13 and a fixing ring 12 are installed on the outside of the springs 22 to prevent the springs 22 from being damaged by the outside. The installation of the first screw 6 and the square plate 5 makes the half-shell 4 engage more tightly.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The warning mechanism 2 includes a housing 201, which is installed at the bottom center of the semi-shell 4. Two male buckles 202 are fixedly connected to the front and rear sides of the top of the housing 201. Two female buckles 207 are fixedly connected to the bottom of the two semi-shells 4 on opposite sides. The male buckles 202 and female buckles 207 engage, allowing the housing 201 to be installed. A fixed round rod 208 is fixedly connected to the middle of the housing 201, and a rotating ring 204 is rotatably connected to the middle of the fixed round rod 208. The left side of the rotating ring 204... A water inlet pipe 203 is fixedly connected to the side. A connecting light rod 205 is fixedly connected to the bottom of the rotating ring 204. A ball 206 is fixedly connected to the bottom of the connecting light rod 205, so that the ball 206 can strike the box 201 and make a sound. Two connecting plates 19 are fixedly connected to the upper and lower ends of the left side of the fixed semi-circular ring 11. Folding plates 18 are rotatably connected to the adjacent left side of the two connecting plates 19. The two folding plates 18 are rotatably connected by a rotating short column 17, so that the device can be placed on a flat surface.

[0042] Specifically, firstly, by correctly installing the female buckle 207, the male buckle 202 and the female buckle 207 can be firmly locked and fixed together. In this way, when a leakage problem occurs at the connection point, the leaked liquid will flow into the box 201 along the bottom of the half-shell 4. In this case, the water inlet pipe 203 inside the box 201 will catch the leaked liquid in time. Over time, when the liquid accumulated in the water inlet pipe 203 reaches a certain amount, the water inlet pipe 203 will rotate downward due to gravity. At the same time, the rotating ring 204 will also rotate accordingly with the rotation of the water inlet pipe 203. In this case, the ball 206 will rotate upward and eventually hit the inner wall of the box 201. This impact action can effectively remind the staff that there is a leakage problem and maintenance work is required. In this way, leakage problems can be detected and dealt with in time, thereby effectively extending the service life of this device. When this device is not in use, the connecting plate 19 will be unfolded through the folding plate 18, through which the device can be placed on a flat surface.

[0043] Reference Figure 1 , Figure 2 and Figure 3 Handles 16 are installed on the left side of the two fixed semicircular rings 11, which are far apart from each other. The upper and lower ends of the handles 16 are threaded with second screws 15.

[0044] Specifically, when it is necessary to move this device, it can be moved by the handle 16 installed by the second screw 15.

[0045] Working principle: First, the two half-shells 4 are installed at the connection of the circular pipe 1 and fixed by multiple positioning pins 3. Then, the right-angle rod 8 is rotated by the circular sleeve 9, causing the pulley 10 to rotate, which in turn causes the connecting flexible rod 7 to retract. Through this retraction, the second clamping plate 20 and the first clamping plate 14 will rotate by rotating the short rod 23, and the spring 22 will retract. The clamping blocks 21, which are fixedly connected to the first clamping plate 14 and the second clamping plate 20 respectively, will move away. At this time, the mechanism is placed on the left side of the half-shell 4, and the installation of the limiting baffle 26 makes it securely and accurately engaged on the outside of the half-shell 4. Then, the right-angle rod 8 is rotated in the opposite direction, causing the multiple springs 22 to rebound and quickly push the first clamping plate 14 and the second clamping plate 20, so that the clamping block 21 at the other end is tightly engaged with the half-shell 4. An annular groove 25 and an elastic sealing ring 24 are opened and installed in the middle of the half-shell 4, which simplifies the pipe connection process, reduces construction difficulty and time consumption, and improves work efficiency.

[0046] First, by installing the female buckle 207, the male buckle 202 is engaged and fixed to it. When a leak occurs at the connection, the liquid will flow into the housing 201 through the bottom of the semi-shell 4. At this time, the water receiving pipe 203 inside the housing 201 will catch the liquid. When a certain amount is accumulated, the water receiving pipe 203 will rotate downward due to gravity, and the rotating ring 204 will also rotate. The ball 206 will rotate upward and hit the housing 201. This serves as a reminder to the staff that maintenance is needed here, thus extending the service life of the device.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
