[0051] See also Figure 1 , Figure 3 and Figure 5 A cable guide insert comprises a first body 1, a second body 2 and a lifting hole 3, wherein the first body 1 and the second body 2 are trumpet-shaped, the first body 1 and the second body 2 comprise a narrow end and an outward-flared end, the outward-flared end is a flared end, and the first body 1 and the second body 2 are butt-jointed at the narrow end to form an insert body;

[0052] the insert body including an inner surface and an outer surface, the inner surface of the insert body defining a hole through the insert body and being bounded on all sides to allow passage of a rope, the inner surface providing a smooth rope running surface, with the rope passing through the hole of the insert body being in direct contact with the rope running surface;

[0053] Four sets of lifting holes 3 are opened on the outer surfaces of the first body 1 and the second body 2 near the outwardly extending ends. The first body 1 and the second body 2 form a mortise and tenon connection structure through six sets of fastening components, and the fastening components are used to fasten the first body 1 and the second body 2 together.

[0054] Furthermore, the cable guide insert is formed by splicing the narrow ends of the first body 1 and the second body 2. The first body 1 and the second body 2 are spliced ​​into the insert body by butting the first narrow end 11 and the second narrow end 21. The shapes of the first body 1 and the second body 2 are expanded outward like a horn. The first body 1 and the second body 2 are formed by their respective narrow ends, the first narrow end 11 and the second narrow end 21, which are respectively expanded outward to the first outward end 12 and the second outward end 22, to form the first body 1 and the second body 2.

[0055] The channel formed by the inner surface of the insert body is determined by the degree of curvature extending from the narrow end to the outward extension end, and can be circular, oblong or elliptical. The inner surface of the insert body defines the contact surface of the rope in the channel. The inner surface of the insert body is smooth and can directly contact the rope passing through the insert body.

[0056] Four lifting holes 3 are optimally drilled on the first main body 1 and the second main body 2 to facilitate the installation of the insert body, making the installation more concise and reliable. At the same time, the mortise and tenon joint structure formed by the first main body 1 and the second main body 2 through the fastening assembly further enhances the overall strength of the insert body.

[0057] See also Figure 1 , Figure 2 and Figure 6 A cable guide insert, the inner surface of the insert body is provided with mounting holes for fastening components at equal angular intervals, the mounting holes include bolt mounting holes and insertion holes 24, the bolt mounting holes extend through a first body 1 and a second body 2 and are exposed at the end surface of the narrow end of the first body 1, the insertion holes 24 extend through the bolt mounting holes and are exposed at the outer surface of the second body 2, and the channel radius of the bolt mounting holes is smaller than the channel radius of the insertion holes 24.

[0058] Furthermore, the mounting holes arranged at equal angles on the inner surface of the insert body make the connection between the first body 1 and the second body 2 more stable, and the first body 1 and the second body 2 are fastened together by the mutual cooperation of six groups of fastening components and the mounting holes; the first bolt mounting hole 13 on the first body 1 and the second bolt mounting hole 23 on the second body 2 correspond to each other, and the first bolt mounting hole 13 is exposed on the inner surface of the first body 1 and the end face of the first narrow end 11, and the second bolt mounting hole 23 is exposed on the narrow end face of the second body 2, and an insertion hole 24 is provided on the outer surface of the second body 2 near the second narrow end 21, and the insertion hole 24 passes through the second bolt mounting hole 23, and the channel size of the bolt mounting hole is smaller than the channel size of the insertion hole 24, so as to provide a placement space for the fastening component.

[0059] See also Figure 1 , Figure 2 and Figure 7 The fastening assembly includes a bolt and a barrel nut. A threaded hole is provided on the top of the barrel nut, and the threaded hole matches the bolt. The bolt mounting hole matches the bolt. The insertion hole 24 matches the barrel nut. The six groups of joints at the narrow end of the first body 1 have beveled 45-degree grooves. The fastening assembly is made of aviation material and is made of ultra-high molecular material.

[0060] Further, when the first body 1 and the second body 2 are spliced ​​together by the fastening assembly, the butt joint with the chamfered 45-degree groove on the end surface of the first narrow end 11 is aligned with the narrow end of the second body 2, so that the first bolt mounting hole 13 and the second bolt mounting hole 23 can be kept in line. First, the barrel nut is placed in the insertion hole 24, and the threaded hole on the top of the barrel nut is aligned with the second bolt mounting hole 23. The bolt is inserted from the opening of the first bolt mounting hole 13 on the inner surface of the first body 1 by rotation, so that the bolt enters the first bolt mounting hole 13, the second bolt mounting hole 23 in sequence, and the first bolt mounting hole 13 is inserted into the second bolt mounting hole 23. The bolt is installed through the mounting hole 23 and the threaded hole on the barrel nut, and the tail of the bolt is located in the bolt mounting hole below the insertion hole 24. The mortise and tenon structure docking of the first body 1 and the second body 2 is achieved through the mutual cooperation of the bolt, the barrel nut and the mounting holes on the insert body, and the 45-degree bevel at the docking point of the first narrow end 11 makes the docking of the first body 1 and the second body 2 more convenient and quick; connecting the first body 1 and the second body 2 by a split fastening connection is convenient for the later maintenance of the insert body.

[0061] The fastening component is made of aviation material, and can be made of materials with good corrosion resistance and tightness, such as titanium alloy material, aluminum alloy material or magnesium alloy material, which makes the fastening component highly reliable.

[0062] See also Figure 4 The outer surface of the insert body is consistent with the inner surface, the rope running surface includes the inner surface of the first body 1 and the inner surface of the second body 2, and the edge position of the mounting hole on the inner surface of the insert body is processed by chamfering process;

[0063] The narrow end and the outward-stretched end are oblong, elliptical or circular, and the narrow end and the outward-stretched end have the same shape. The main body of the insert is made of ultra-high molecular material.

[0064] Furthermore, by chamfering all positions on the inner surface of the insert body that may be contacted by the cable, including the edge of the first bolt mounting hole 13 on the inner surface of the first body 1, chamfering the edge of the first bolt mounting hole 13 exposed on the inner surface of the first body 1 reduces the risk of cable wear.

[0065] After the first body 1 and the second body 2 are docked, the complete channel formed by the inner surface of the first body 1 and the inner surface of the second body 2 is the running contact channel of the rope. The rope running surface defines the traveling surface of the rope and can also prevent the rope from falling off.

[0066] The material of the inner surface of the insert body is a polymer material, which may be polyimide, epoxy resin or other polymer composite plastics. Polyimide is a polymer material widely used in the aerospace field. It has good high temperature strength, chemical stability, flame retardancy and impact resistance. Epoxy resin is a polymer material obtained through an epoxidation reaction. It has the characteristics of high strength, high rigidity, wear resistance and chemical corrosion resistance. The polymer material on the inner surface of the insert body can achieve precise control of the product thickness in the production process, so that the product channel can provide the maximum cable passage aperture. The production difficulty and production cost of the insert body made of polymer material are low, and the strength of use is sufficient.

[0067] See also Figure 8-Figure 13 , showing in sequence a structural schematic diagram, a front view, a rear view, a top view, a top cross-sectional view and a side cross-sectional view of the first body 1;

[0068] Further, the first outwardly extending end 12 and the first narrow end 11 of the first body 1 have the same shape, which may be an oblong, elliptical or circular shape. The first narrow end 11 extends toward the first outwardly extending end 12 to form a parabolic outwardly extending wall. The outwardly extending wall formed on the inner surface of the first body 1 changes according to the shapes of the first narrow end 11 and the first outwardly extending end 12. The inner surface of the first body 1 is convexly outwardly extending. The channel formed on the inner surface of the first body 1 may have different profiles according to the shapes of the first narrow end 11 and the first outwardly extending end 12.

[0069] The first bolt mounting hole 13 provided on the inner surface of the first body 1 extends through the inner surface to the end surface of the first narrow end 11 , and a bolt can be installed and inserted from the opening of the first bolt mounting hole 13 on the inner surface.

[0070] See also Figure 14-Figure 20 , showing in sequence the structural schematic diagram, front view, rear view, top view, top sectional view, side sectional view and partial front sectional view of the second body 2, wherein the partial front sectional view of the second body 2 is a front sectional view of the position of the insertion hole 24 on the second body 2.

[0071] Further, the basic shape of the second body 2 is similar to that of the first body 1, and the size of the second body 2 can be the same as that of the first body 1, can be larger than that of the first body 1, or can be smaller than that of the first body 1, but the second narrow end 21 of the second body 2 must be the same size and shape as the first narrow end 11 of the first body 1, ensuring that the inner surface of the insert body joint is smooth;

[0072] The space of the insertion hole 24 is sufficient to accommodate the barrel nut. The bolt rotated and inserted from the first body 1 needs to pass through the barrel nut installed in the insertion hole 24. Through the mutual cooperation of the bolt and the barrel nut, the first body 1 and the second body 2 are tightly connected with the mortise and tenon joint structure.
