Description

Technical Field

[0001] This utility model relates to the field of double-wall corrugated pipes, specifically a PVC-H anhydrous phosphogypsum modified high-strength double-wall corrugated pipe. Background Technology

[0002] High-density polyethylene (HDPE) double-wall corrugated pipe is a new type of pipe with an annular outer wall and a smooth inner wall. After years of development and improvement, it has evolved from a single product to a complete product series. PVC is a synthetic polymer plastic, and modified anhydrous phosphogypsum is a modified phosphogypsum product. Double-wall corrugated pipes made of PVC and anhydrous phosphogypsum can increase the strength of the double-wall corrugated pipe. In the existing technology, the main connection method for two double-wall corrugated pipes is the socket connection. The spigot end is inserted into the socket end, and then the two double-wall corrugated pipes are tightened by a pull wire tightener. However, the socket connection of double-wall corrugated pipes is relatively troublesome to operate and also requires the application of a large amount of lubricant, which reduces the connection efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, the socket connection of double-wall corrugated pipes is relatively cumbersome and requires the application of a large amount of lubricant, which reduces connection efficiency. This invention proposes a PVC-H anhydrous phosphogypsum modified high-strength double-wall corrugated pipe.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a PVC-H anhydrous phosphogypsum modified high-strength double-wall corrugated pipe, including a first double-wall corrugated pipe, a second double-wall corrugated pipe is provided on one side of the first double-wall corrugated pipe, and a buckling mechanism is provided on the surface of the second double-wall corrugated pipe. The latching mechanism includes a hollow block, the inner cavity of which is fixedly connected to the surface of a first double-walled corrugated pipe. A first hollow groove is formed in the inner cavity of the hollow block, and a spring is fixedly connected to the inner cavity of the first hollow groove. A latching block is fixedly connected to the top of the spring. A connecting block is fixedly connected to the surface of the second double-walled corrugated pipe. An L-shaped slider is provided on one side of the latching block, and one side of the L-shaped slider is fixedly connected to one side of the connecting block.

[0005] Preferably, the surface of the hollow block is provided with a second hollow groove, and a connecting plate is slidably connected to the inner cavity of the second hollow groove. One side of the connecting plate is fixedly connected to one side of the snap-fit ​​block.

[0006] Preferably, a triangular block is fixedly connected to one side of the connecting plate, and a threaded ring block is provided on one side of the triangular block. The inner cavity of the threaded ring block is threadedly connected to the surface of the hollow block, and a fourth hollow groove is provided on the surface of the hollow block.

[0007] Preferably, a telescopic rod is fixedly connected to the inner cavity of the first hollow groove, and the top of the telescopic rod is fixedly connected to the bottom of the snap-fit ​​block.

[0008] Preferably, the hollow block has a third hollow groove in its inner cavity, and a stop block is slidably connected to the inner cavity of the third hollow groove. The top of the stop block is fixedly connected to the bottom of the connecting plate.

[0009] Preferably, the inner cavity of the second double-walled corrugated pipe is provided with a sealing ring, and the surface of the sealing ring is fixedly connected to the inner cavity of the first double-walled corrugated pipe.

[0010] Preferably, a reinforcing rod is fixedly connected to the surface of the second double-walled corrugated pipe, and one side of the reinforcing rod is fixedly connected to one side of the connecting block.

[0011] The advantages of this utility model are: This invention involves moving a second double-walled corrugated pipe to one side of a first double-walled corrugated pipe. The second double-walled corrugated pipe, via a connecting block, moves an L-shaped slider into the interior of a hollow block. The L-shaped slider then presses against the inclined surfaces of multiple locking blocks, causing these blocks to move. Simultaneously, the locking blocks compress springs, causing them to contract. When the L-shaped slider reaches one side of the locking blocks, the springs spring the locking blocks back to their original positions, locking the L-shaped slider in place. This ensures the L-shaped slider remains stable inside the hollow block, preventing it from detaching. This achieves the connection between the first and second double-walled corrugated pipes, making the connection more convenient. Simply moving the L-shaped slider into the hollow block eliminates the need for a socket-type connection, resulting in higher connection efficiency. This solves the problem of the cumbersome socket-type connection of the first double-walled corrugated pipe, which requires applying a large amount of lubricant, thus reducing connection efficiency.

[0015] 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 scope of protection of the present utility model.

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a PVC-H anhydrous phosphogypsum modified high-strength double-wall corrugated pipe. (Refer to...) Figure 1-3 A PVC-H anhydrous phosphogypsum modified high-strength double-wall corrugated pipe includes a first double-wall corrugated pipe 1, a second double-wall corrugated pipe 2 is provided on one side of the first double-wall corrugated pipe 1, and a snap-fit ​​mechanism 3 is provided on the surface of the second double-wall corrugated pipe 2. The first double-wall corrugated pipe 1 and the second double-wall corrugated pipe 2 can be connected together through the snap-fit ​​mechanism 3.

[0017] The latching mechanism 3 includes a hollow block 301. The inner cavity of the hollow block 301 is fixedly connected to the surface of the first double-walled corrugated pipe 1. The inner cavity of the hollow block 301 is provided with a first hollow groove 302. A spring 303 is fixedly connected to the inner cavity of the first hollow groove 302. A latching block 304 is fixedly connected to the top of the spring 303. A connecting block 305 is fixedly connected to the surface of the second double-walled corrugated pipe 2. An L-shaped slider 306 is provided on one side of the latching block 304. One side of the L-shaped slider 306 is fixedly connected to one side of the connecting block 305. The interior of the hollow block 301 can be used to house the L-shaped slider 306, which can be connected to the second double-walled corrugated pipe 2 via the connecting block 305. When the second double-walled corrugated pipe 2 is connected to the first double-walled corrugated pipe 1, the connecting block 305 can move the L-shaped slider 306 into the interior of the hollow block 301. The interior of the hollow block 301 can also house the locking block 304, which has a sloping side that can be pressed and moved by the L-shaped slider 306 inside the hollow block 301. A spring 303 at the bottom of the locking block 304 supports the locking block 304 and can be compressed and contracted by the moving locking block 304. It can also spring the locking block 304 back to its original position, thus allowing the locking block 304 to automatically lock the L-shaped slider 306 in place. The slider 306 allows the L-shaped slider 306 to be stably placed inside the hollow block 301, thereby connecting the first double-walled corrugated pipe 1 and the second double-walled corrugated pipe 2. This makes the connection between the first double-walled corrugated pipe 1 and the second double-walled corrugated pipe 2 more convenient, as the L-shaped slider 306 only needs to be moved into the hollow block 301, eliminating the need for a socket connection and improving connection efficiency. The connecting block 305 at the bottom of the spring 303 allows the locking block 304 to have sufficient space to move, while also allowing the spring 303 to retract. Multiple sets of spring 303 and locking blocks 304 are provided, and the connecting block 305 and the L-shaped slider 306 are in a circular shape, allowing multiple sets of locking blocks 304 to better lock and limit the L-shaped slider 306.

[0018] Reference Figure 3 The surface of the hollow block 301 is provided with a second hollow groove 4. A connecting plate 5 is slidably connected to the inner cavity of the second hollow groove 4. One side of the connecting plate 5 is fixedly connected to one side of the snap-fit ​​block 304. The interior of the second hollow groove 4 can be used to place the connecting plate 5, so that the connecting plate 5 can be connected to the snap-fit ​​block 304. The connecting plate 5 can move to drive the snap-fit ​​block 304 to move together, so that the snap-fit ​​block 304 can be disengaged from the L-shaped slider 306, thereby removing the L-shaped slider 306 and disassembling the first double-walled corrugated pipe 1 and the second double-walled corrugated pipe 2. Multiple sets of the second hollow groove 4 and the connecting plate 5 are also provided, each corresponding to each snap-fit ​​block 304.

[0019] Reference Figure 3A triangular block 7 is fixedly connected to one side of the connecting plate 5. A threaded ring block 6 is provided on one side of the triangular block 7. The inner cavity of the threaded ring block 6 is threaded to the surface of the hollow block 301. A fourth hollow groove 13 is provided on the surface of the hollow block 301. Since there are multiple connecting plates 5, it is inconvenient to move multiple connecting plates 5 at the same time when separating the first double-walled corrugated pipe 1 and the second double-walled corrugated pipe 2. Therefore, the threaded ring block 6 can be rotated to move on the surface of the hollow block 301, and the movement can squeeze multiple triangular blocks 7, so that multiple triangular blocks 7 move at the same time, and simultaneously drive the connecting plate 5 and the snap-fit ​​block 304 to move away from the L-shaped slider 306. This makes the movement of multiple snap-fit ​​blocks 304 more convenient. The fourth hollow groove 13 provided at the bottom of the triangular block 7 allows the triangular block 7 to have space to move.

[0020] Reference Figure 3 The inner cavity of the first hollow groove 302 is fixedly connected to a telescopic rod 8. The top of the telescopic rod 8 is fixedly connected to the bottom of the snap-fit ​​block 304. The telescopic rod 8 can be used to support and reinforce the snap-fit ​​block 304, making the snap-fit ​​block 304 more stable on the top of the spring 303 and less prone to shaking and instability.

[0021] Reference Figure 3 The hollow block 301 has a third hollow groove 9 in its inner cavity. A stop block 10 is slidably connected to the inner cavity of the third hollow groove 9. The top of the stop block 10 is fixedly connected to the bottom of the connecting plate 5. The stop block 10 can be used to block the second hollow groove 4, making it difficult for foreign objects to enter the interior of the hollow block 301. The third hollow groove 9 can prevent the stop block 10 from obstructing the movement of the connecting plate 5.

[0022] Reference Figure 2 The inner cavity of the second double-wall corrugated pipe 2 is provided with a sealing ring 11. The surface of the sealing ring 11 is fixedly connected to the inner cavity of the first double-wall corrugated pipe 1. The sealing ring 11 is located at the connection between the first double-wall corrugated pipe 1 and the second double-wall corrugated pipe 2. It can be used to increase the sealing performance of the connection between the first double-wall corrugated pipe 1 and the second double-wall corrugated pipe 2, so that the liquid inside the first double-wall corrugated pipe 1 and the second double-wall corrugated pipe 2 is not easy to leak out.

[0023] Reference Figure 3 A reinforcing rod 12 is fixedly connected to the surface of the second double-wall corrugated pipe 2. One side of the reinforcing rod 12 is fixedly connected to one side of the connecting block 305. The reinforcing rod 12 can reinforce the connection between the second double-wall corrugated pipe 2 and the connecting block 305, making the connecting block 305 more secure on the surface of the second double-wall corrugated pipe 2 and less prone to breakage and deformation.

[0024] Working principle: When using this device, firstly, the second double-wall corrugated pipe 2 is moved to one side of the first double-wall corrugated pipe 1. The second double-wall corrugated pipe 2 will drive the L-shaped slider 306 to move into the interior of the hollow block 301 through the connecting block 305. Then, the L-shaped slider 306 will press the inclined surfaces of multiple locking blocks 304, causing the multiple locking blocks 304 to move. At the same time, the locking blocks 304 will compress the spring 303 to retract. When the L-shaped slider 306 moves to one side of the locking block 304, the spring 303 retracts. 3. The locking block 304 will spring back to its original position and lock the L-shaped slider 306, so that the L-shaped slider 306 can be stably inside the hollow block 301 and cannot be removed from the hollow block 301. At this time, the effect of connecting the first double-wall corrugated pipe 1 and the second double-wall corrugated pipe 2 can be achieved, making the connection of the first double-wall corrugated pipe 1 and the second double-wall corrugated pipe 2 more convenient. Just move the L-shaped slider 306 into the hollow block 301. There is no need to use the socket connection method, making the connection efficiency higher. When it is necessary to separate the first double-walled corrugated pipe 1 and the second double-walled corrugated pipe 2, simply rotate the threaded ring block 6 to move it on the surface of the hollow block 301. The moving threaded ring block 6 will press the inclined surfaces of multiple triangular blocks 7 to make them move. At the same time, the multiple triangular blocks 7 will drive multiple snap-fit ​​blocks 304 to move together through multiple connecting plates 5, so that the snap-fit ​​blocks 304 can disengage from the L-shaped slider 306. At this time, the L-shaped slider 306 can be removed to separate the first double-walled corrugated pipe 1 and the second double-walled corrugated pipe 2. This solves the problem that the socket connection of the first double-walled corrugated pipe 1 is relatively troublesome and requires a lot of lubricant, which reduces the connection efficiency.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
