Technical Field

[0001] This utility model relates to the field of plastic pipe connection technology, specifically to a plastic pipe that is easy to position and assemble. Background Technology

[0002] Plastic pipes are a general term for pipes made of plastic materials. They are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. Pipes are generally spliced ​​in use to connect multiple sections into a longer pipe for use.

[0003] A search revealed that the Chinese patent "A Plastic Pipe for Easy Splicing" (authorization announcement number CN222316293U) allows for easy connection to a second pipe by setting a connecting pipe at the end of the first pipe. Furthermore, by incorporating a first mounting block, a second mounting block, a limiting block, a limiting groove, a positioning block, and a positioning groove on the first and second connectors, it enables rapid splicing and installation of the two pipes, improving the convenience and practicality of splicing. Additionally, the inclusion of a first mounting plate, a second mounting plate, screw holes, and positioning bolts allows for double locking between the two pipes, ensuring the strength of the pipe connection and improving its sealing performance.

[0004] Although the aforementioned application can splice pipes, when using the device to disassemble and assemble pipes, workers need to press two positioning blocks simultaneously and keep the pipes moving synchronously while pressing the positioning blocks in order to complete the disassembly and assembly work, which increases the difficulty of the operation for workers.

[0005] Based on this, the present invention designs a plastic pipe that is easy to position and splice in order to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a plastic pipe that is easy to position and splice.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A plastic pipe for easy positioning and splicing includes two circular pipes 100 and an installation mechanism 200. The installation mechanism 200 includes a fixing ring 210 fixedly connected to the surface of one of the circular pipes 100. One end of the fixing ring 210 has an annular groove 211. A retaining plate 212 is fixedly connected to the inner wall of the annular groove 211. The surface of the other circular pipe 100 is fixedly connected to an installation ring 220. A rotating ring 221 is rotatably connected to the inner wall of the installation ring 220. One end of the rotating ring 221 is rotatably connected to a connecting ring 222. The surface of the connecting ring 222 has an installation groove 223 and a retaining groove 224. The installation groove 223 and the retaining groove 224 communicate with each other. Two installation plates 230 are fixedly connected to the surfaces of the fixing ring 210 and the installation ring 220. Two adjacent installation plates 230 are installed by bolts and nuts. A reinforcing component 240 is provided on the surface of the fixing ring 210.

[0030] In this embodiment of the present invention, when installing the two circular tubes 100, the connecting ring 222 is inserted into the annular groove 211, and the two mounting plates 230 on the fixing ring 210 are aligned with the two mounting plates 230 on the mounting ring 220. When the connecting ring 222 is inserted into the annular groove 211, the retaining plate 212 enters the mounting groove 223 and pushes the connecting ring 222 to continue moving into the annular groove 211. When the connecting ring 222 can no longer move, the retaining plate 212 and the retaining groove 224 are on the same vertical plane, and the opposite ends of the two circular tubes 100 are pressed together, and the opposite ends of the fixing ring 210 and the mounting ring 220 are pressed together. At this time, the operator rotates the connecting ring 222 clockwise by ninety degrees. (Refer to...) Figure 2 After the connecting ring 222 is rotated 90 degrees clockwise, the clamping plate 212 is fully inserted into the clamping groove 224. At this time, the initial installation of the fixing ring 210 and the mounting ring 220 is completed, thus completing the initial installation of the two round tubes 100. Each of the four mounting plates 230 has two mounting holes on its surface. After the opposite ends of the fixing ring 210 and the mounting ring 220 are pressed together, the two mounting plates 230 on the fixing ring 210 are respectively attached to the opposite sides of the two mounting plates 230 on the mounting ring 220. At this time, the two adjacent attached mounting plates 230 are installed using bolts and nuts, thus completing the installation of the fixing ring 210 and the mounting ring 220, and completing the installation of the two round tubes 100.

[0031] In this embodiment of the utility model, when installing the two round tubes 100, simply insert the connecting ring 222 into the annular groove 211 and rotate it 90 degrees so that the clamping plate 212 engages with the clamping groove 224. The initial installation of the two round tubes 100 is completed by fixing the ring 210 and mounting the ring 220. The installation and fixing of the two round tubes 100 is completed by installing the two mounting plates 230 on the fixing ring 210 and the two mounting plates 230 on the mounting ring 220 with bolts and nuts. When disassembling the two round tubes 100, release the fixing of the mounting plates 230 and rotate the connecting ring 222 90 degrees in the opposite direction to release the installation of the two round tubes 100 and separate the two round tubes 100. The disassembly and assembly steps do not need to be operated simultaneously, which reduces the difficulty of operation for workers.

[0032] In some embodiments, such as Figure 2-4As shown, in a preferred embodiment of the present invention, the reinforcing component 240 includes an arc-shaped plate 241 slidably connected to the surface of the fixing ring 210. One end of the arc-shaped plate 241 is fixedly connected to a plurality of ring-shaped clamping rods 242. Two connecting plates 243 are fixedly connected to the surface of the arc-shaped plate 241. The surface of the connecting plates 243 is provided with mounting holes. One end of the rotating ring 221 is fixedly connected to a slider 244. The other end of the slider 244 passes through the mounting ring 220 and is fixedly connected to a reinforcing plate 245. The surface of the reinforcing plate 245 is provided with a plurality of ring-shaped fixing holes 246.

[0033] In this embodiment of the utility model, one end of the mounting ring 220 is provided with an arc-shaped groove that matches the slider 244. The surface of the reinforcing plate 245 is bent into an arc shape. After the two round tubes 100 are fixed, the reinforcing plate 245 and the arc-shaped groove coincide on the horizontal plane, thereby protecting the arc-shaped groove. When the reinforcing plate 245 is rotated 90 degrees, multiple locking rods 242 correspond one-to-one with multiple fixing holes 246. The diameter of the locking rods 242 matches the diameter of the fixing holes 246. The connecting plate 243 has two mounting holes on its surface, and the two mounting holes on the connecting plate 243 correspond to the mounting plates 230 on the fixing ring 210. The two mounting holes correspond one-to-one. After the fixing ring 210 and the mounting ring 220 are initially installed, the arc plate 241 is pushed to move, so that the arc plate 241 drives multiple locking rods 242 to enter the corresponding fixing holes 246 respectively. At this time, when the two adjacent mounting plates 230 are installed with bolts and nuts, the bolts pass through the mounting holes of the connecting plate 243. After the two adjacent mounting plates 230 are fixed with bolts and nuts, the two connecting plates 243 and the two mounting plates 230 on the fixing ring 210 will be pressed and fixed at the same time, so that the multiple locking rods 242 are stably engaged with the corresponding fixing holes 246.

[0034] In this embodiment of the utility model, when fixing the two round tubes 100, multiple clamping rods 242 are used to engage with multiple fixing holes 246 one by one. At the same time as fixing the two adjacent mounting plates 230 with bolts and nuts, the arc plate 241 is fixed simultaneously. This helps to keep the connecting ring 222 stable when the clamping plate 212 engages with the clamping groove 224, ensuring the stability of the engagement between the clamping plate 212 and the clamping groove 224, thereby enhancing the stability of the two round tubes 100 after installation and fixing.

[0035] In some embodiments, such as Figure 4-5As shown in a preferred embodiment of this utility model, one end of the mounting ring 220 has two circular holes 225. A fixing block 250 is fixedly connected to the surface of the reinforcing plate 245. A limiting rod 251 is slidably connected to the inner wall of the fixing block 250. A limiting ring 252 is fixedly connected to the surface of the limiting rod 251. A spring 253 is fixedly connected between one end of the limiting ring 252 and the inner wall of the fixing block 250. The included angle between the centers of the two circular holes 225 is ninety degrees, and the diameter of the limiting rod 251 matches the diameter of the circular holes 225.

[0036] In this embodiment of the invention, in the initial state, the limiting rod 251 is engaged with one of the circular holes 225. When it is necessary to rotate the connecting ring 222 90 degrees clockwise, the limiting rod 251 is pulled to move away from the circular hole 225. The limiting ring 252 compresses the spring 253, releasing the engagement between the limiting rod 251 and the circular hole 225. At this time, the connecting ring 222 can be rotated 90 degrees clockwise by the reinforcing plate 245 driven by the limiting rod 251. Simultaneously, the limiting rod 251 aligns with the other circular hole 225. The force on the limiting rod 251 is released, the spring 253 drives the limiting ring 252 to reset, and drives the limiting rod 251 into the corresponding circular hole 225, whereby the limiting rod 251 and the circular hole 225 are engaged again.

[0037] In this embodiment of the utility model, the limiting rod 251 is engaged with one of the round holes 225, which helps to ensure the stability of the connecting ring 222 in the initial state. The limiting rod 251 is engaged with the other round hole 225, which helps to initially limit the rotation of the connecting ring 222, thereby ensuring the stability during the installation process.

[0038] In some embodiments, such as Figure 3-4 As shown, in a preferred embodiment of the present invention, guide blocks 260 are fixedly connected to one side of the two mounting plates 230, and through holes 270 are opened on the surface of the other two mounting plates 230.

[0039] In this embodiment of the present invention, two guide blocks 260 are mounted on two mounting plates 230 on the surface of the fixing ring 210. The two mounting plates 230 on the surface of the mounting ring 220 are provided with through holes 270. When the connecting ring 222 is inserted into the annular groove 211, the guide blocks 260 are inserted into the corresponding through holes 270. At this time, the retaining plate 212 is aligned with the mounting groove 223, and the mounting holes of the two mounting plates 230 on the fixing ring 210 are aligned with the mounting holes of the two mounting plates 230 on the mounting ring 220.

[0040] In this embodiment of the utility model, the arrangement of the guide block 260 and the through hole 270 facilitates the installation of the two mounting plates 230 on the fixing ring 210 and the two mounting plates 230 on the mounting ring 220 by the operator. Furthermore, it facilitates the better alignment of the mounting groove 223 and the card plate 212 when the operator inserts the connecting ring 222 into the annular groove 211, thereby improving the convenience of installation.

[0041] In some embodiments, such as Figure 3-4 As shown, in a preferred embodiment of the present invention, the overall shape of the card plate 212, the overall shape of the mounting groove 223, and the overall shape of the card slot 224 are all quarter-circular rings, and the shape and size of the card slot 224 match the shape and size of the card plate 212.

[0042] In this embodiment of the utility model, the surface of the card plate 212 is bent into an arc shape. When the card plate 212 enters the card slot 224, both sides and one end of the card plate 212 are in contact with the inner wall of the card slot 224, which helps to ensure the stability of the card plate 212 when it is engaged with the card slot 224.

[0043] In some embodiments, such as Figure 3 As shown, in a preferred embodiment of the present invention, a sealing ring 280 is embedded in one end of the fixing ring 210, and the sealing ring 280 is a rubber component.

[0044] In this embodiment of the utility model, when the opposite ends of the fixing ring 210 and the mounting ring 220 are attached and installed, the surface of the sealing ring 280 contacts and abuts against one end of the mounting ring 220, thereby improving the sealing performance of the connection between the fixing ring 210 and the mounting ring 220 after installation.

[0045] In some embodiments, such as Figure 3 As shown, in a preferred embodiment of the present invention, a movable block 247 is fixedly connected to the inner surface of the arc plate 241, and the surface of the movable block 247 is slidably connected to the inner wall of the fixed ring 210.

[0046] In this embodiment of the utility model, a groove matching the movable block 247 is provided on the upper surface of the fixed ring 210. The surface of the movable block 247 is slidably connected to the inner wall of the groove, which is beneficial to limit the movement path of the arc plate 241. Both sides of the movable block 247 are fixedly connected to the corrugated cover of the rubber component. The other two ends of the two corrugated covers are fixedly connected to the inner walls of the groove respectively. The protective cover protects the groove and prevents impurities from being trapped in the groove during the use of the device.
