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.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a pluggable roller connector for aircraft landing gear that avoids the influence of harsh environments, including a connector 1, a roller 2 inserted at the lower end of the connector 1, multiple sets of bolts 3 inserted on the connector 1, and a nut 4 screwed on the other end of the bolt 3.

[0021] Furthermore, the connectors 1 are connected by bolts 3 and nuts 4 to form a spiral locking structure, thereby facilitating the assembly and use of the connectors 1 through the bolts 3 and nuts 4 assembly.

[0022] The outer sides of the bolts 3 and nuts 4 are respectively provided with spiral grooves on the connector 1, and protective covers 5 are spirally spiraled in the spiral grooves. The protective covers 5 are provided with rubber plates 6 on their outer walls. It should be noted that the protective covers 5 are made of high-strength materials such as stainless steel and aluminum alloy, so as to effectively ensure their own protective effect.

[0023] Furthermore, the protective cover 5 forms a spiral locking structure with the connector 1 through spiral grooves, thereby facilitating the protection of the bolt 3 and its related connecting parts through the spirally installed protective cover 5 assembly.

[0024] The protective cover 5 has a rubber pad 7 inside, and the rubber pad 7 has a locking block 8. The locking block 8 is inserted into the through hole on the protective cover 5, and a spiral block 9 is spiraled inside the locking block 8.

[0025] Furthermore, the rubber pad 7 forms a spiral locking structure with the protective cover 5 through the locking block 8, the spiral block 9, and the corresponding rubber pad 7 can be installed inside the protective cover 5 through the spiral block 9, so as to limit the bolt 3 and the nut 4 and provide shock absorption protection through the corresponding rubber pad 7.

[0026] The protective cover 5 has multiple sets of limiting brackets 10 inside, and an insulation board 11 is placed between the limiting brackets 10 and the protective cover 5. One end of the rubber pad 7 is inserted between the insulation boards 11. It should be noted that this utility model is a pluggable roller connector for aircraft landing gear that avoids the influence of harsh environments. All components are standard parts or components known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0027] Furthermore, the insulation board 11 has an arc-shaped structure, and the insulation board 11 forms a spiral locking structure with the protective cover 5 through the limiting frame 10, so that the insulation board 11 placed in a limiting position can avoid the impact of the low external environment on the bolt 3 and its related components.

[0028] Working Principle: When using a pluggable roller connector for aircraft landing gear designed to withstand harsh environments, the connector 1 and roller 2 are first assembled using multiple sets of bolts 3 and nuts 4 via a spiral connection. This allows the roller 2 to function properly in the aircraft. After the bolts 3 and nuts 4 are installed, they are spirally mounted onto the connector 1 via the threads on the outer wall of the protective cover 5. The protective cover 5 protects the bolts 3 and nuts 4, while the rubber plate 6 further protects the spiral groove and related components, thus preventing the connection from being affected by harsh external environments. Before using the protective cover 5, the appropriate rubber pad 7 can be selected based on the bolts 3 and nuts 4, and the locking block 8 is used to secure the connection. The connector is placed inside the protective cover 5 and screwed on by the bolt block 9. The screw-mounted rubber pad 7 can limit and dampen the bolt 3 and nut 3, further ensuring the working stability of the connecting components on the connector 1. If the aircraft needs to pass through a low-temperature environment during operation, the insulation plate 11 is limited by the limiting frame 10. At the same time, the rubber pad 7 inserted in the limiting plate 11 provides auxiliary limiting for the insulation plate 11. Thus, the insulation plate 11 prevents the low temperature environment from affecting the connecting components of the connector 1. This is the usage process of the plug-in roller connector for aircraft landing gear that avoids the influence of harsh environments.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
