Description

Technical Field

[0001] This utility model relates to a pipe structure, specifically a reinforced polypropylene pipe structure. Background Technology

[0002] The core function of pipes is to construct fluid transmission channels and structural support systems. Their core applications include four major functional modules: water supply and drainage, energy medium transmission, building pipe network construction, and adaptation to special scenarios. Common pipe materials include metal pipes and polypropylene pipes. Among them, polypropylene pipes have the advantages of meeting food-grade standards, being non-toxic and harmless, being suitable for drinking water transportation, and not containing heavy metals or other harmful substances.

[0003] Common polypropylene pipes also have the characteristics of resisting various chemical corrosions, including acid and alkaline environments, and are suitable for industrial fluid transportation and other scenarios. These industrial fluids have high pollution intensity and high corrosiveness, and once a leak occurs, its impact is significant.

[0004] Because common polypropylene pipes are joined using hot-melt welding, the strength of the joint cannot be guaranteed after the hot-melt treatment, making leakage easy. Furthermore, due to limitations in the installation environment and process, it is difficult to ensure the concentricity of the two pipes during the connection process. This results in bending, twisting, and shear stress at the joint after the pipes are connected. Polypropylene pipes have poor low-temperature resistance, especially in severe winter conditions, where they easily become brittle, greatly increasing the stress at the joint and making the pipe more likely to break, which is detrimental to the safe transportation of media.

[0025] 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.

[0026] Please see Figures 1-4 As an embodiment of the present utility model, the reinforced polypropylene pipe structure includes a pipe body 1; both ends of the pipe body 1 are equipped with connectors 11.

[0027] It also includes multiple sets of ribs 12 installed on the connector 11; the multiple sets of ribs 12 are equidistantly arranged along the circumference of the connector 11; the ribs 12 are provided with fitting grooves 1201; the fitting grooves 1201 are narrowed in width, and the narrowing direction is away from the connector 11 and towards another connector 11;

[0028] Additive 2 is disposed within the fitting groove 1201;

[0029] Upper limit structure; the upper limit structure is used to limit the upper part of the additive 2;

[0030] Lower limit structure; the lower limit structure is used to limit the lower part of the additive 2.

[0031] In this embodiment, the pipe body 1, the connector 11, and the rib plate 12 are all made of polypropylene.

[0032] The connector 11 reduces the difficulty of connecting the pipes to each other, thereby ensuring that the deviation between the centerlines of the installed pipes meets the usage requirements.

[0033] Multiple sets of ribs 12 are equidistantly distributed along the circumference of the connector 11. The ribs 12 increase the bending, shearing and torsion resistance of the connector 11 and the pipe body 1, which can prevent the pipe from breaking due to improper installation or use at the pipe connection, thereby improving the safety and service life of the pipe.

[0034] By adding additive material 2 inside the rib plate 12 to form a reinforcing layer, the ring stiffness and compressive strength of the pipe connection are further improved; the strength of the rib plate 12 can also be improved, avoiding the rib plate 12 from breaking due to improper installation or use; and the cold deformation temperature of the pipe connection is reduced by additive material 2, avoiding the pipe from freezing and cracking due to severe cold, thus improving the applicability of the pipe.

[0035] The additive manufacturing process involves sliding the material into the fitting groove 1201, which can reduce production costs, avoid large-scale modifications to existing production processes, and improve production efficiency.

[0036] After the additive 2 is installed, the upper part of the additive 2 is limited by the upper limit structure and the lower part of the additive 2 is supported and limited by the lower limit structure. This can prevent the additive 2 from separating from the rib plate 12 and can protect the additive 2 through the rib plate 12, thereby improving the service life of the pipe.

[0037] As a further embodiment of this invention, the additive material 2 is made of glass fiber.

[0038] In this embodiment, glass fiber can significantly improve the tensile strength, flexural strength and cold deformation temperature of polypropylene; through the cooperation between the glass fiber additive 2 and the rib 12, the pipe can be prevented from freezing and cracking due to severe cold, thus improving the applicability of the pipe; and the rib 12 can protect the additive 2, thereby improving the service life of the pipe.

[0039] As a further embodiment of this utility model, the additive 2 includes a base rod 21; both ends of the base rod 21 are equipped with symmetrically arranged connecting rods 22; multiple sets of connecting rods 22 are inclined, and the distance between the multiple sets of connecting rods 22 gradually decreases, the decreasing direction being away from the connecting member 11 and towards another connecting member 11; a top rod 23 is installed on the end of each connecting rod 22; an upper limit post 2301 is installed on the side of the multiple sets of top rods 23 that is far away from each other; a second fixing block 2302 is installed on the side of the upper limit post 2301 that is close to the connecting member 11.

[0040] In this embodiment, the width of the fitting groove 1201 is tapering, and the tapering direction is away from the connector 11 and towards the other connector 11. The distance between the feature and the connecting rod 22 gradually decreases, and the feature that tapes away from the connector 11 and towards the other connector 11 cooperates with each other (the size of the fitting groove 1201 is the same as the size of the additive 2). This can reduce the difficulty of installing the additive 2 and reduce the stress deformation of the glass fiber additive 2. That is, as the installation process increases, the extrusion force of the fitting groove 1201 wall on the upper limit post 2301 will increase. After the extrusion force is transmitted to the connecting rod 22, it will cause the connecting rods 22 to move closer to each other (bending deformation). Compared with the flared or flat type, its deformation is relatively small (that is, it only occurs at the end of the installation process, and the extrusion force is small), which can prevent the additive 2 from breaking or cracking, thus avoiding damage to the pipe performance.

[0041] As a further embodiment of this utility model, the upper limit position structure includes multiple sets of upper limit position grooves 1202 formed on the rib plate 12; the multiple sets of upper limit position grooves 1202 are symmetrically arranged on both sides of the fitting groove 1201; and the upper limit position grooves 1202 are slidably engaged with the upper limit position post 2301.

[0042] In this embodiment, at the end of the additive manufacturing process, the upper limit post 2301 will slide into the upper limit groove 1202 under the elastic force of the connecting rod 22.

[0043] When the pipe is subjected to force causing the connector 11 to deform (especially in the case of bending), the bottom plane of the upper limit post 2301 on the additive 2 in the rib 12 away from the deformation direction will be pressed and engaged with the bottom wall of the upper limit groove 1202, while the upper plane of the upper limit post 2301 on the additive 2 in the rib 12 close to the deformation direction will be pressed and engaged with the upper wall of the upper limit groove 1202, and the upper limit post 2301 will slide in the upper limit groove 1202; this can prevent the deformation force from being transmitted to the additive 2 and causing the additive 2 to be damaged and broken, and can also improve the stability of the connection between the additive 2 and the rib 12, ensuring that the performance of the pipe is not greatly damaged when it is deformed under force, and will not affect normal use.

[0044] As a further embodiment of this utility model, a first fixing block 1203 is installed in the upper limit groove 1202; and the first fixing block 1203 is disposed at the connection end between the upper limit groove 1202 and the fitting groove 1201; the first fixing block 1203 and the second fixing block 2302 abut against each other.

[0045] In this embodiment, the size of the upper limit groove 1202 is larger than the size of the upper limit post 2301. Therefore, the upper limit post 2301 can smoothly drive the second fixing block 2302 to slide into the upper limit groove 1202. After entering, the squeezing and abutting cooperation between the first fixing block 1203 and the second fixing block 2302 can increase the difficulty of the upper limit post 2301 separating from the upper limit groove 1202 after the pipe is deformed by force, thus ensuring the performance of the pipe.

[0046] As a further embodiment of this utility model, the lower limiting structure includes a lower limiting post 1204 installed in the fitting groove 1201, and the lower limiting post 1204 abuts against the bottom rod 21.

[0047] In this embodiment, the lower limit post 1204 is made of the same material as the connector 11.

[0048] The thickness of the fitting groove 1201 is slightly greater than the thickness of the additive 2 (to reduce installation difficulty); and the setting of the lower limit post 1204 reduces the conduction area of ​​the fitting groove 1201 (less than the thickness of the additive 2). Therefore, during the installation of the additive 2, the lower limit post 1204 will be deformed by the compression of the additive 2, so as to ensure that the additive 2 (bottom rod 21) can pass smoothly over the lower limit post 1204. Afterwards, the lower limit post 1204 will deform and recover under its own elastic force, thereby supporting the additive 2 and preventing the additive 2 from separating from the rib plate 12.

[0049] As a further embodiment of this utility model, the surface on which the lower limiting post 1204 mates with the bottom rod 21 is arc-shaped.

[0050] In this embodiment, the arc-shaped surface can reduce the difficulty of installing the additive 2 and reduce the friction area between the additive 2 and the lower limit post 1204, thus protecting the lower limit post 1204 and reducing the friction loss of the additive 2, thereby improving the service life of the pipe.

[0051] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
