Description

Technical Field

[0001] The utility model belongs to the field of aviation support equipment manufacturing, and in particular relates to a sliding frame locking mechanism of an aircraft radome maintenance platform. Background Art

[0002] During the disassembly and maintenance of the aircraft radome, an inspection platform is required. In order to ensure fine-tuning of the position between the inspection platform and the radome to achieve stable and reliable support for the radome, a slide is usually provided on the inspection platform, and the slide is slidably installed on the corresponding slide rail groove. After the slide position is adjusted in place, the slide needs to be reliably locked on the slide rail groove. At present, the commonly used locking mechanism is a latch locking mechanism, which is achieved by installing a latch on the slide and providing latch holes arranged at equal intervals on the slide rail groove. When locking is required, the latch is inserted into the latch hole to achieve locking of the slide. The disadvantage of using this locking mechanism is that, since the positions of the latch holes can only be arranged at equal intervals, it is impossible to achieve precise locking when locking, which in turn affects the position accuracy.
