Description

Technical Field

[0001] This invention belongs to the field of engine assembly technology, specifically a protective device for medium and large-sized irregular conduit joints during engine assembly. Background Technology

[0002] Engines have complex structures and require high precision, necessitating stringent quality control during manufacturing. Within an engine are numerous piping components, including many conduit joints in shapes such as hexagons, pentagons, triangles, and irregular ellipses. These joints are typically large in size or have a wide extension area, making them susceptible to damage during transportation or transfer at the assembly site.

[0003] To address the aforementioned impact issues, existing protective devices include plugs that mate with the internal or external threads of the conduit connector, directly nested rubber heads, or protective cloth bags. However, in actual use, none of these protective methods provide adequate impact protection and fail to offer sufficient cushioning when an impact occurs.

[0004] Among them, plugs that mate with the internal or external threads of conduit fittings must be matched with these threads. However, the dimensions of these threads are not standardized and vary greatly. During disassembly and assembly after commissioning, the large number of different sizes leads to a significant waste of time. Furthermore, many threads are of similar size, and since the plugs are made of hard PVC plastic, the threads are prone to damage due to size mismatch, resulting in the formation of plastic particles. These particles may enter the pipeline, increasing the burden on components such as lubricating oil and fuel filters, thereby affecting their lifespan.

[0005] Among them, the directly nested rubber head provides partial protection and cannot completely prevent collisions.

[0006] Among them, cloth covers are not very effective in preventing bumps and knocks, and are prone to leaving stains.

[0007] In summary, the protection of large-sized, irregularly shaped catheter connectors remains a major problem that urgently needs to be solved. Summary of the Invention

[0008] The present invention aims to provide a shockproof sleeve for medium and large-sized irregular conduit joints, which improves the protection effect of large and medium-sized irregular conduit joints during engine disassembly and assembly and pipeline transportation, enhances protection efficiency, reduces unnecessary working time, and improves the protection measures for similar parts.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The anti-collision sleeve for medium and large-sized irregular conduit connectors includes a cylindrical body and a tapered end. The axial ends of the cylindrical body are connected to the large outer diameter end of the tapered end, wherein:

[0011] The cylindrical body has a circular cross-section perpendicular to its own axis. The outer ring of the circular ring is composed of trapezoids and triangles that are alternately distributed on the outer ring circumference. Similarly, the inner ring of the circular ring is composed of trapezoids and triangles that are alternately distributed on the inner ring circumference.

[0012] The tapered end has a circular cross-section perpendicular to its own axis. The inner and outer ring profiles of the cross-section at the large outer diameter end connected to the cylindrical body are consistent with the cylindrical body. The inner and outer ring profiles of the cross-section between the large and small outer diameter ends are composed of trapezoids and triangles alternately distributed on the inner and outer ring circumferences. The area of ​​the trapezoids and triangles decreases linearly from the large outer diameter end to the small outer diameter end. Both the inner and outer ring profiles of the cross-section at the small outer diameter end are circular.

[0013] The trapezoid has its base facing outwards and its top edge, which is parallel to the base, facing inwards; the triangle has its vertices facing outwards and the edges corresponding to those vertices facing inwards.

[0014] The cylindrical body and the conical end are made of a material that combines elasticity, wear resistance, and is not prone to shedding.

[0015] Furthermore, in the annular cross-section of the cylindrical body, the trapezoids on the inner ring contour and the trapezoids on the outer ring contour are similar trapezoids, the triangles on the inner ring contour and the triangles on the outer ring contour are similar triangles, and the corresponding sides of the trapezoids are parallel to each other, and the corresponding sides of the triangles are parallel to each other.

[0016] Furthermore, in the annular cross-section of the cylindrical body, there are trapezoids with equal central angles on the inner and outer ring contours, and a triangle is set at the bisector of the central angle between every two trapezoids.

[0017] Furthermore, in the annular cross-section of the cylindrical body, the diameter of the inner ring is larger than the diameter of the outer ring at the small outer diameter end of the conical end.

[0018] Furthermore, the inner wall surface formed by the inner ring contour of the cylindrical body is also provided with anti-detachment protrusions, which protrude from the inner wall surface towards the axis of the cylindrical body.

[0019] Furthermore, the anti-detachment protrusion includes an upper anti-detachment protrusion with a right-angled trapezoidal cross-section and a lower anti-detachment protrusion with a rectangular cross-section, wherein the aforementioned cross-section is a plane passing through the axis of the cylindrical main body.

[0020] The anti-collision sleeve of this invention has a universal structure, suitable for large and medium-sized irregular-shaped conduit connectors. It not only provides better protection for the conduit connectors, but its versatility also greatly reduces the time required for the classification and use of traditional protective devices, achieving more complete protection for the conduit connectors. This invention has a long service life and low manufacturing cost (the universal kit is cheaper than the dedicated kit), further improving work efficiency during disassembly and installation.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. All modifications, substitutions and alterations made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0027] This invention designs an anti-collision sleeve suitable for various medium and large-sized irregular-shaped conduit connectors. For the conduit connectors being protected, there is no need for protective kits of specific sizes and shapes to match them. Instead, a unified universal protective kit is used, which reduces the classification and adaptation process during disassembly and assembly, improves production efficiency, increases the buffer protection effect, and reduces the protection cost.

[0028] Material selection for impact protection sleeves: The impact protection sleeves are made of silicone or rubber materials that have a certain degree of elasticity, are wear-resistant, and have good overall quality, making it less likely to shed debris. Such materials can provide a certain degree of flexibility when the local structure is insufficient to meet the stretch requirements, while the elastic material can better prevent violent impacts, resulting in a more obvious cushioning effect.

[0029] The anti-collision sleeve adopts a variable-size design (the size is variable through the elastic deformation of the material, with a design size range of Φ45~Φ65) to achieve versatility. The variable-size implementation scheme is divided into three parts:

[0030] (1) The outer parts of the cylindrical main body 1 and the conical end 2 adopt a combined structure, such as Figure 1 From a cross-sectional perspective, it utilizes a combination of triangular and trapezoidal cross-sections, with 12 of each type. The two types of cross-sections are arranged in a circumferential pattern to form a dodecagon. Each triangular or trapezoidal cross-section is designed with a circumferential angle of 15°, thus forming a 24-sided polygon. This design covers all shapes and angles of conduit fittings, including triangles, quadrilaterals, hexagons, and irregular ellipses (because this combination can perfectly support the sides of hexagons, pentagons, and triangles, and also provides good support for irregular ellipses). It can meet all the needs of irregular conduit fittings, and the trapezoidal and triangular structures can more comprehensively resist impacts of different degrees of force.

[0031] (2) The inner sides of the cylindrical body 1 and the conical end 2 also use a combination of triangular and trapezoidal cross sections, consistent with the outer side. The inner structure provides sufficient friction to the protected conduit connector to ensure that the connector does not undergo unnecessary displacement. At the same time, the inner structure can also work with the outer structure to provide sufficient support to protect the conduit connector.

[0032] (3) The inner side of the cylindrical body 1 is designed with anti-detachment protrusions, which are arranged in two rows around the circumference. The first row (upper anti-detachment protrusion 31) is designed in the upper part of the anti-collision sleeve, and the cross section is a right trapezoid, which facilitates the entry of the connector and restricts its detachment; the second row (lower anti-detachment protrusion 32) is designed in the lower part of the anti-collision sleeve, and the cross section is a rectangle, which restricts the connector from detaching.

[0033] (4) The extended design of the bottom and sides is conducive to the size expansion and contraction of the anti-collision sleeve. The bottom is a conical bottom, and the sides are a circumferential ring-shaped wave-like structure (an undulating fold made of trapezoids and triangles).

[0034] The main feature of this anti-collision sleeve is that it protects the conduit through its materials and variable design while achieving universal compatibility with non-standard connectors. Within the universal range, it replaces the previous cloth bag installation with a simple press-fit installation method, saving time in finding and installing plugs according to the conduit size and avoiding plastic debris falling off during the assembly of plastic plugs and conduits, thus providing protection against unwanted objects.

[0035] like Figure 1 As shown, triangular and trapezoidal cross sections are combined and matched in an intersecting manner, with 12 of each type of cross section. The two types of cross sections are arranged in an intersecting pattern around the circumference to form a dodecagon. The circumferential angle of a single triangular or trapezoidal cross section is designed to be 15°, with an inner diameter of 60mm and an outer diameter of 70mm.

[0036] like Figure 2 , Figure 3As shown, when the anti-collision sleeve is applied to medium-sized conduit fittings, the inner wall surface contacts the pipe fitting while working with the outer wall surface to form a stronger support structure. In the event of a collision, it avoids damage to the internal structure caused by the surface impact. Furthermore, the contact point between the anti-collision sleeve and the pipe features a gradually tapering conical end 2 design, allowing the sleeve to clamp tightly when the pipe diameter is less than 60mm. The inner side of the cylindrical body 1 is designed with anti-detachment protrusions in two rows around the circumference. The first row is the upper anti-detachment protrusion 31, designed to be located in the upper half of the anti-collision sleeve, with a right-angled trapezoidal cross-section, facilitating the fitting's entry and preventing detachment. The second row is the lower anti-detachment protrusion 32, designed to be located in the lower half of the anti-collision sleeve, with a rectangular cross-section, preventing the fitting from detaching. When applied to large-sized fittings, the wall surface is expanded, making it nearly circular, increasing the inner diameter while maintaining protective performance.

[0037] like Figure 4 As shown, the bottom surface is designed to be expandable. Conical ends 2 are designed at both ends of the cylindrical body 1. In the case of protecting large-sized joints, the conical ends 2 can be tilted at a variable angle to achieve the purpose of expanding the bottom surface and shrinking in conjunction with the wall surface.

Although illustrative specific embodiments of the invention have been described above to facilitate understanding by those skilled in the art, it should be understood that the invention is not limited to the scope of the specific embodiments. Various modifications are readily apparent to those skilled in the art as long as they fall within the spirit and scope of the invention as defined and determined by the appended claims, and all inventions utilizing the concept of this invention are protected.
