Description

Technical Field

[0001] The utility model relates to the technical field of aircraft control rods, in particular to an aircraft control rod which is easy to disassemble. Background Art

[0002] As one of the key components of the aircraft control system, the aircraft control stick is also called the joystick. It connects the pilot to the control system. Its main function is to provide control instructions to the aircraft flight control system to achieve three-axis control of the aircraft.

[0003] After searching, the existing Chinese patent with publication number CN202321624702.8 discloses an aircraft control stick that is easy to disassemble. By providing a fixing hole, a limit slider, a fixing bolt and a mounting sleeve, when the control stick body needs to be disassembled, the fixing bolt is screwed out of the fixing hole. After the fixing bolt is screwed out of the fixing hole, the control stick body and the limit slider will lose fixation. After the control stick body and the limit slider lose fixation, the control stick body can be disassembled, thereby facilitating the replacement of the control stick body and the inspection of other components.

[0004] The above technical solution has the following defects: such an aircraft control stick structure is installed by bolts, and the control stick body can be disassembled and repaired after removing multiple sets of bolts. However, in actual use, the length of the control stick is fixed and it is inconvenient to adjust the length according to the actual situation of the driver. In order to facilitate disassembly and maintenance and further improve the applicability of the aircraft control stick, an aircraft control stick that is easy to disassemble is proposed. The aircraft control stick and the control stick base can be temporarily connected by screws, so that it is more convenient to install and disassemble without holes, and the length can be adjusted according to the actual body shape of the driver, so that the driver can operate the control stick more comfortably.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
