Detailed description of the invention
Below by detailed description of the invention, the utility model is further described:
Refer to Fig. 1, Fig. 2, it is a kind of Small General Aircraft draw bar of the utility model structural representation.A kind of Small General Aircraft draw bar of the utility model comprises the first connecting cylinder 1, first axle 2, first strut 3, connecting rod 4, auricle 5, bolt 6, handle 7, first bar 8, Quick-release pin 9, second bar 10, second axle 11, the 3rd axle 12, sleeve 13, the 4th axle 14, second strut 15, the 5th axle 16, second connecting cylinder 17.Wherein, described sleeve 13 is arranged on bar 8, auricle 5 is fixed on the first bar 8 by bolt 6, second bar 10 is arranged on the first bar 8 by Quick-release pin 9, first connecting cylinder 1 is arranged on auricle 5 by bolt 6, first connecting cylinder 1 is connected with the first strut 3 by the first axle 2, first strut 3 is connected with sleeve 13 by the first axle 2, second connecting cylinder 17 is connected with the second strut 15 by the 5th axle 16, second strut 15 is connected with sleeve 13 by the 5th axle 16, connecting rod 4 is connected with sleeve 13 by the 4th axle 14, connecting rod 4 is connected with handle 7 by the second axle 11, handle 7 is connected with auricle 5 by the 3rd axle 12.
Please refer to Fig. 3 and Fig. 5, wherein, Fig. 3 is a kind of Small General Aircraft draw bar of the utility model sleeve schematic diagram when opening, schematic diagram when Fig. 5 is a kind of Small General Aircraft draw bar transport of the utility model.During the utility model one Small General Aircraft draw bar towing aircraft, first towards draw bar top driving handle 7, handle 7 rotates around the 3rd axle 12, meanwhile handle 7 passes through the second axle 11 drivening rod 4 to draw bar top movements, connecting rod 4 is with moving sleeve 13 to draw bar top movements by the 4th axle 14, sleeve 13 is respectively by the first axle 2, 5th axle 16 drives the first strut 3, second strut 15 moves, first strut 3 and the second strut 15 are again respectively by the first axle 2, 5th axle 16 promotes the first connecting cylinder 1, second connecting cylinder 17 outwards moves, draw bar is opened.Take off Quick-release pin 9, extract the second bar 10, then insert Quick-release pin 9, length of draw bar is increased.When a kind of Small General Aircraft draw bar of the utility model transports, pull up Quick-release pin 9, push back the second bar 10, then insert Quick-release pin 9, length of draw bar is shortened.Driving handle 7 bottom draw bar, handle 7 rotates around the 3rd axle 12, meanwhile handle 7 is moved bottom draw bar by the second axle 11 drivening rod 4, connecting rod 4 is moved with the bottom of moving sleeve 13 to draw bar by the 4th axle 14, sleeve 13 drives the first strut 3, second strut 15 to move respectively by the first axle 2, the 5th axle 16, first strut 3 and the second strut 15 promote the first connecting cylinder 1, second connecting cylinder 17 inwardly move respectively by the first axle 2, the 5th axles 16 again, make draw bar closed and locked.
The utility model realizes the opening of draw bar connector, closed locked by the quadric chain of handle, connecting rod, sleeve, auricle, strut, realize elongation and the shortening of draw bar by the first bar and the second shank diameter difference, when realizing length of draw bar change by Quick-release pin, the second bar is fixing.Its structure is simple, lightweight, reliably easy to connect with aircraft, and body of rod length can regulate, and makes to operate during flight crew's towing aircraft comfortable.
