[0002] With the increase of combat training missions of aviation units, the frequency of combat aircraft performing missions at remote airports is increasing, and the follow-up speed of support personnel and support equipment has become an important factor restricting the rapid deployment of combat aircraft. Therefore, support equipment The development of equipment towards miniaturization and portability has become an important direction of improvement. For ladder tools that are frequently used in aviation maintenance support, in order to achieve the characteristics of miniaturization and portability, it is necessary to design a unique The folding rod connection and locking structure that can withstand a large specific load can meet the application requirements of different occasions. The key is to ensure that the connection and locking mechanism can still be locked reliably when it is subjected to a specific form of large load or vibration. The problem of not delaying the timing of military deployment or causing accidents due to loosening or shaking

Embodiment
[0016] Embodiment: A fast self-locking folding rod connection device, including a folding rod and a tensioning mechanism, the folding rod includes a first folding rod 1 and a second folding rod 2, and a pair of butt ears are arranged on the lower side of the right end surface of the first folding rod 1 3. A first sleeve 4 is provided on the lower side of the left end surface of the second folding rod 2. The first folding rod 1 and the second folding rod 2 use the first connecting bolt 5 and the first connecting nut 6 to pass through the ear 3 and The first sleeve 4 is hinged together at the rear, and the first folding rod 1 and the second folding rod 2 can be folded around the hinged position. A second sleeve 8 is arranged on the side, and the tensioning mechanism includes a front side plate 9 and a rear side plate 10, and a first connecting rod 11 and a second connecting rod are respectively hinged between the two ends of the front side plate 9 and the rear side plate 10. 12....

The invention discloses a quick self-locking folding rod connecting device. A first folding rod and a second folding rod are hinged together by using a first connecting bolt and a first connecting nutto penetrate through a connecting lug and a first sleeve, then the upper end faces of the first folding rod and the second folding rod are separately hinged with a tension mechanism, the end providedwith a single lug piece on a stop mechanism is hinged with the end provided with a double-lug piece on the tension mechanism by using a second connecting bolt and a second connecting nut, and a locking nut is mounted on the stop mechanism through a stop screw hole; and a second connecting rod on the tension mechanism is placed in a groove on the first folding rod, then the stop mechanism fixes the locking nut to a connecting hole on the tension mechanism around the second connecting bolt, and at the same time, a stop block is inserted into a gap between the first folding rod and the second folding rod to realize axial limiting. The quick self-locking folding rod connecting device can reliably withstand large axial tensile load and folding direction bending load.
Description
technical field [0001] The invention relates to the field of mechanical design, in particular to a fast self-locking folding rod connecting device capable of bearing axial tensile load and bending load in the folding direction. Background technique [0002] With the increase of combat training missions of aviation units, the frequency of combat aircraft performing missions at remote airports is increasing, and the follow-up speed of support personnel and support equipment has become an important factor restricting the rapid deployment of combat aircraft. Therefore, support equipment The development of equipment towards miniaturization and portability has become an important direction of improvement. For ladder tools that are frequently used in aviation maintenance support, in order to achieve the characteristics of miniaturization and portability, it is necessary to design a unique The folding rod connection and locking structure that can withstand a large specific load can ...
