Description

Technical Field

[0001] This utility model relates to a pipe fitting, and more specifically, to a high-compression-resistant honeycomb pipe fitting. Background Technology

[0002] Current pipe fittings are typically manufactured using a single-piece extrusion molding process from resin materials to form pipes suitable for conveying specific materials. Some applications require pipe fittings with higher performance requirements, and the material used is usually selected based on the application scenario or the material being conveyed to meet these needs. However, current pipe fittings suffer from poor strength performance. Reinforcement is often achieved by increasing the pipe wall height, but this provides only a limited increase in strength and results in poor adaptability.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a high-pressure-resistant honeycomb pipe fitting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-compression-resistant honeycomb pipe fitting, comprising an inner pipe body and a pipe fitting outer shell, wherein the inner pipe body comprises a plurality of single pipe bodies, each single pipe body being fixedly connected to the other, the cross-section of the inner pipe body having a porous structure, the inner circumferential surface of the pipe fitting outer shell being adapted to the outer circumferential surface of the inner pipe body, and the pipe fitting outer shell being sleeved on the outer circumference of the inner pipe body and bonded and fixed to each other.

[0006] The present invention is further configured such that an inner hole is formed inside the single tube, and the single tubes are arranged in parallel.

[0007] The present invention is further configured such that each single tube is integrally formed, and adjacent single tubes share a portion of the tube wall.

[0008] The present invention is further configured such that the cross-section of the single tube is a regular hexagonal structure, and the cross-section of the inner tube is a honeycomb structure.

[0009] The present invention is further configured such that the inner tube body includes seven sets of single tubes, one set of single tubes is located in the middle, and the remaining single tubes surround the outer periphery.

[0010] The present invention is further configured such that the cross-section of the single tube is circular or square.

[0011] The present invention is further configured such that the outer periphery of the inner tube body and the inner periphery of the outer shell of the fitting are bonded and fixed together by an adhesive.

[0012] The outer shell of the pipe fitting is made of metal, carbon fiber, or glass fiber.

[0013] In summary, this utility model has the following beneficial effects:

[0014] By setting the pipe fitting to a double-layer structure with an inner pipe body and an outer pipe shell, the inner pipe body directly contacts the material being conveyed, allowing for the selection of appropriate materials based on the material being conveyed. The outer pipe shell forms a protective layer structure on the outside, protecting the entire pipe fitting and enabling it to adapt to the required environment, thus exhibiting better strength performance.

[0015] The inner tube has a porous honeycomb structure in its cross-section. This structure can effectively disperse external pressure and reduce local stress concentration, thereby improving the overall compressive strength of the pipe. Moreover, the honeycomb structure has good energy absorption characteristics, which can absorb energy when subjected to impact, reducing the impact of vibration and impact on the pipe.

[0026] 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 protection scope of the present utility model.

[0027] Example 1

[0028] This embodiment discloses a high-compression-resistant honeycomb pipe fitting, referring to... Figures 1-4 As shown, the device includes an inner tube body 1 and a pipe outer shell 2. The inner tube body 1 comprises several individual tube bodies 11, which are fixedly connected to each other, resulting in a porous cross-section for the entire inner tube body 1. The sidewalls of each individual tube body 11 can form a supporting structure, which greatly increases the strength of the entire inner tube body 1.

[0029] In addition, a pipe fitting shell 2 is fitted outside the inner pipe body 1. The inner circumferential surface of the pipe fitting shell 2 is adapted to the outer circumferential surface of the inner pipe body 1, and the pipe fitting shell 2 is fitted onto the outer circumference of the inner pipe body 1. A gap is formed between the inner circumferential surface of the pipe fitting shell 2 and the outer circumferential surface of the inner pipe body 1. An adhesive 3 is applied to the gap, and the two can be bonded and fixed together to form a whole pipe fitting. The adhesive 3 can fill the gap between the inner circumferential surface of the pipe fitting shell 2 and the outer circumference of the inner pipe body 1 to form an adhesive layer, thus bonding the two together as a whole.

[0030] The outer casing 2 provides additional protection for the inner pipe body 1, further increasing the overall strength of the pipe fitting.

[0031] In this embodiment, the individual tubes 11 are arranged in parallel, and an inner hole 10 is formed inside each individual tube 11. Multiple inner holes 10 can form a porous structure. Multiple inner holes 10 can each form a different conveying channel.

[0032] Each individual tube 11 is made of plastic and can be integrally molded, with adjacent individual tubes 11 sharing a portion of the tube wall 12. During the production process, the inner tube 1 can be integrally extruded and molded. The inner tube 1 can be made of corrosion-resistant materials, enabling it to be used in harsh environments, resisting chemical corrosion and oxidation, and extending its service life.

[0033] The outer shell 2 of the pipe fitting has higher strength than the inner pipe body 1. Specifically, it can be made of lightweight, high-strength materials that can form a protective barrier on the outside of the pipe fitting. For example, it can be made of metal materials such as aluminum alloy or titanium alloy, or materials such as carbon fiber or glass fiber, or high-performance resin materials with appropriate strength properties. The specific choice can be made according to the usage environment of the pipe fitting.

[0034] Reference Figure 2As shown, the inner tube 1 has a honeycomb cross-section, while the individual tubes 11 have a regular hexagonal cross-section. This honeycomb structure provides excellent strength, resulting in a stable and high-strength structure for the entire inner tube 1. Typically, the inner tube 1 comprises seven sets of hexagonal individual tubes 11, evenly arranged, with one set located in the center and the remaining tubes surrounding the periphery. For example, when material is conveyed through the innermost central cavity, part of the cavity may be hollow, allowing air and gaps to be contained within. The hollow outer periphery of the inner cavity forms an air layer, providing some heat and sound insulation.

[0035] Alternatively, the cross-section of the single tube 11 in the inner tube 1 can also be circular or square, etc., which can also meet the requirements of a porous structure, increase the internal support and strength of the fitting, and meet the usage requirements of the fitting. Structures with different cross-sectional shapes can be combined in an appropriate arrangement, and the extrusion die can be specifically designed.

[0036] During the production process, the inner tube body 1 and the outer shell 2 are processed separately. The inner tube body 1 is generally processed by extrusion molding; the outer shell 2 is processed and shaped using appropriate processes depending on the selected material. Then, the inner tube body 1 and the outer shell 2 are nested together, bonded together with a high-strength PU adhesive, and then cured, thus bonding and fixing the inner tube body 1 and the outer shell 2 into a single integrated structure. The entire fitting has a two-layer structure, with the honeycomb-shaped inner tube body 1 enhancing the strength of the inner core, while the outer shell 2 provides external protection. Together, they significantly improve the fitting's compressive strength, rigidity, and overall strength, adapting to the requirements of special application scenarios.

[0037] Example 2

[0038] This embodiment discloses a high-compression-resistant honeycomb pipe fitting, which is based on Embodiment 1 and further refers to... Figure 5-8 Please provide a detailed explanation.

[0039] Reference Figure 5 As shown, in this embodiment, the inner tube 1 is divided into several segments, and the segments are connected by connectors 4 to form an interlocking structure at the connection point, which can maintain the stability of the connection point.

[0040] The connector 4 includes a connector sleeve 41 and several connector tubes 42, wherein the outer circumferential contour of the connector tubes 42 is consistent with the inner circumferential contour of the pipe shell 2, and the connector sleeve 41 can be inserted into the pipe shell 2; several inner circumferential cavities 411 are formed on the inner circumference of the connector sleeve 41, the two ends of the inner circumferential cavity 411 are through, and correspond one-to-one with the shape and position of each single pipe body 11.

[0041] The connector tube 42 is located on the inner circumference of the connector sleeve 41. The shape and position of the connector tube 42 correspond one-to-one with the single tube body 11. Both ends of the connector tube 42 extend from the connector sleeve 41, forming two tube ends 421. The two tube ends 421 of the connector tube 42 can be inserted into the inner holes 10 of the inner tube bodies 1 on both sides, forming a mutually nested structure. Furthermore, the outer circumferential contour of the tube ends 421 is adapted to the shape contour of the inner hole 10, and after insertion, a relatively tight nested structure can be formed, which can improve the stability of the connection at the joint. Moreover, the mutually nested structure can also form a relatively tortuous connection surface at the joint. To improve the sealing performance at the joint, sealant can be pre-applied to the insertion joint.

[0042] Reference Figure 5 As shown, during the manufacturing process, the connector sleeve 41 and the connector tube 42 can be integrally formed, meaning that the two are integrally formed, with only two ends of the connector tube 42 extending from the connector sleeve 41. A gap 43 is formed between the tube ends 421 of each connector tube 42, allowing them to be interlocked and fixed with the inner tube body 1 during insertion.

[0043] Because the gap 43 between the tube ends 421 of each connector tube 42 is small during the production process, defects are easily generated during the molding process. Therefore, the connector sleeve 41 and the connector tube 42 can also adopt a separate structure. (Referring to the figure...) Figures 6-8 As shown, the split connector 4 will be described in detail.

[0044] Reference Figure 6 , Figure 7 As shown, each connector tube 42 adopts a split structure. The cross-sectional shape of the connector tube 42 is adapted to the shape of the inner hole 10, and can be partially (i.e., tube end 421) inserted into the inner hole 10.

[0045] To achieve positioning between the connector cannula 42 and the connector sleeve 41, a limiting block 44 is integrally fixedly connected to the outer wall of the connector cannula 42. The limiting block 44 is arranged along the length direction, and limiting ends 441 are formed at both ends of the limiting block 44. The inner circumference of the connector sleeve 41 has a plurality of inner circumferential cavities 411, and the inner circumferential cavities 411 have a plurality of supporting walls 412 constructed in a honeycomb structure, which serve as the sidewalls of the inner circumferential cavities 411.

[0046] In this embodiment, the inner circumferential cavity 411 has six supporting walls 412 along its axial direction. Limiting grooves 413 are formed on the supporting walls 412, and the width of the limiting grooves 413 is adapted to the shape of the limiting blocks 44. When the connector tube 42 is inserted into the inner circumferential cavity 411 of the connector sleeve 41, it can be locked and limited by the limiting blocks 44. After the limiting blocks 44 are inserted into the limiting grooves 413, they can be blocked and positioned by the limiting end 441 of the limiting blocks 44 abutting against the bottom surface behind the limiting grooves 413, thus maintaining the stability of the insertion position.

[0047] Furthermore, in this embodiment, each set of connectors 4 can be limited by two connector tubes 42, as shown in the reference. Figure 6 , Figure 8 As shown.

[0048] Two connector sleeves 41 are respectively installed at both ends of the connector tube 42, and the connector tube 42 is inserted into the corresponding holes of the connector sleeves 41. The limiting blocks 44 on the outside of the connector tube 42 are respectively embedded in the corresponding limiting grooves 413 of the two connector sleeves 41. The two connector sleeves 41 are spaced apart from each other.

[0049] When the connector 4 and the inner tube 1 are inserted into each other, the end 421 of the connector tube 42 is inserted into the inner hole 10 of the inner tube 1, and the end face of the inner tube 1 and the end face of the connector sleeve 41 press against each other. When the two inner tubes 1 are installed axially, the end face of the inner tube 1, the end face of the connector sleeve 41, the bottom surface of the limiting groove 413, and the limiting block 44 form a state of mutual pressing, which can ensure the stability of the two inner tubes 1 during axial installation and prevent the connector tube 42 from moving in the length direction between the two inner tubes 1.

[0050] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
