[0002] In the field of industrial pipelines, cast stone pipes are widely used in mining, metallurgy, chemical and other scenarios for conveying highly abrasive media due to their high wear resistance, corrosion resistance and high temperature resistance. However, the traditional connection method of cast stone pipes has significant defects and can hardly meet the needs of modern industry for pipeline installation efficiency, sealing and maintenance convenience.
[0003] Traditional cast stone pipes are mostly connected by flanges or welding. During installation, each bolt needs to be tightened individually or welding needs to be done on-site. This is not only time-consuming and labor-intensive, but also requires high technical skills from the installers. Especially in space-constrained conditions, the operation is extremely difficult, leading to a longer construction period. Therefore, it is necessary to improve the above-mentioned problems.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example: See Figure 1-4This utility model discloses a quick-connect cast stone pipe, comprising a cast stone pipe 1, a first connecting plate 2 at one end of the cast stone pipe 1, and a second connecting pipe 12 at the other end. The second connecting pipe 12 has a sealing groove 3, and multiple guide grooves 5 are equidistantly arranged on its inner wall. Multiple locking blocks 4 are symmetrically arranged on both sides of the inner wall of the guide grooves 5. Multiple sliders 6 corresponding to the guide grooves 5 are equidistantly arranged on the outer wall of the first connecting plate 2 along the outer wall of the cast stone pipe 1. The guide grooves 5 of the second connecting pipe 12 cooperate with the sliders 6 of the first connecting plate 2 to facilitate quick positioning and insertion of the cast stone pipes 1, improving the efficiency of pipe installation. The locking blocks 4 are symmetrically arranged on the inner wall of the guide grooves 5, providing a structural basis for subsequent locking and clamping, reducing alignment time and operational difficulty during installation, and solving the problem of low installation efficiency in traditional connection methods. The guide grooves 5 and sliders 6 are made of high-manganese steel with strong wear resistance, capable of withstanding multiple insertion and removal operations, extending service life. Multiple locking holes 7 corresponding to the locking blocks 4 are opened on the outer walls of both sides of the sliders 6. A sealing gasket 11 corresponding to the sealing groove 3 is provided on the inner wall of the disc 2; the cooperation between the locking block 4 and the locking hole 7 allows the cast stone pipe 1 to be quickly locked after insertion without the need for bolt tightening, further improving the connection efficiency; the sealing gasket 11 is made of nitrile rubber and is set corresponding to the sealing groove 3. It achieves sealing through compression during pipe connection. Its excellent oil resistance and wear resistance can effectively prevent leakage of highly abrasive media and avoid the problem of insufficient sealing in traditional connections; the second connecting pipe 12 has a telescopic hole at one end face of the locking block 4. A spring 15 is fixedly attached to the bottom surface of the telescopic hole. One end of the spring 15 is fixedly attached to the locking block 4, and a connecting post 8 is sleeved inside the spring 15; the spring 15 is a common cylindrical helical compression spring. Its good elasticity and fatigue life can stably provide elastic force to push the locking block 4 out, ensuring that the locking block 4 automatically embeds into the locking hole 7 to achieve quick elastic locking; the connecting post 8 cooperates with the spring 15 to guide and limit the extension and retraction of the locking block 4, ensuring the stability and reliability of the locking structure and improving the convenience and firmness of the connection.
[0020] In this utility model, one end of the connecting column 8 is fixedly connected to the locking block 4, and the other end of the connecting column 8 passes through the bottom end of the telescopic hole and is fixedly connected to the connecting plate 14. A rectangular groove for sliding of the connecting plate 14 is opened in the second connecting tube 12. A pull rope 9 is fixedly connected to the middle of one side of the connecting plate 14. The pull rope 9 is made of 304 stainless steel wire braided rope, which is high in strength and corrosion resistant. It drives the locking block 4 to retract against the elastic force of the spring 15 through the connecting plate 14 and the connecting column 8, which facilitates the release of the locking state during disassembly. The rectangular groove provides sliding space for the connecting plate 14, making the disassembly operation smoother. A pull block 10 is fixedly connected to one end of the pull rope 9. Multiple limiting holes 13 are equidistantly opened along the axial side of the outer wall of the second connecting tube 12. The pull block 10 is movably disposed in the limiting holes 13. 10 is made of high-strength engineering plastic material, which makes it easy for operators to pull the pull rope 9. The limiting hole 13 limits the pull block 10 to prevent the pull rope 9 from being pulled too much during disassembly and causing structural damage. The limiting holes 13 are set at equal intervals, which can fix the pull block 10 in a suitable position after disassembly for easy use next time, further improving the convenience of maintenance. A ring of anti-slip pads 16 is attached to one end face of the second connecting pipe 12. The anti-slip pads 16 are made of neoprene rubber with anti-slip texture on the surface, which can effectively increase friction and has weather resistance and corrosion resistance. While assisting the guide groove 5 and the slider 6 in precise positioning, it reduces repeated operations caused by sliding misalignment during installation, improves installation efficiency and centering accuracy, and extends the service life of the cast stone pipe 1.
[0021] Working principle: When using this utility model, firstly, align one end of the cast stone pipe 1 with the first connecting plate 2 with the second connecting pipe 12 of another cast stone pipe 1, so that the slider 6 on the first connecting plate 2 is aligned with the guide groove 5 on the inner wall of the second connecting pipe 12, and pushed along the axial direction of the guide groove 5. The guide groove 5 limits and guides the slider 6, quickly achieving alignment of the two pipe axes; as the slider 6 goes deeper, the locking block 4 protrudes from the inner wall of the guide groove 5 under the elastic force of the spring 15. When the locking hole 7 on the slider 6 moves to the corresponding position, the locking block 4 is inserted into the locking hole 7 to form an elastic locking, completing the pipe locking; at the same time, the first connecting plate 12 is aligned with the second connecting pipe 12. The sealing gasket 11 on the inner wall of the connecting plate 2 corresponds to and fits into the sealing groove 3 of the second connecting pipe 12. Under the push of the pipe, the sealing gasket 11 is squeezed and deformed, filling the gap of the sealing groove 3 to achieve a reliable seal. When disassembling, pull the pull block 10. The pull block 10 drives the connecting plate 14 and the connecting column 8 to move against the elastic force of the spring 15 through the pull rope 9, so that the locking block 4 is disengaged from the locking hole 7, and the slider 6 can slide along the guide groove 5 to separate the pipe. In addition, the anti-slip pad 16 on the end face of the second connecting pipe 12 increases the friction to assist in positioning. The cooperation between the guide groove 5 and the slider 6 ensures that the pipe axis is aligned. At this point, the device is in use.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
