Draw ring takes reliable and stable mechanism to press microswitch, so as to connect emergency extension undercarriage signal.
Invention content
The purpose of patent of the present invention, is solved when aircraft is in state of flight and landing gear switch is in disabler, has been assisted
It rises and falls holder function into emergency extension.In order to realize the purpose, the present invention provides one kind, and there is emergency extension to rise and fall holder function
Control draw ring, which is characterized in that including protection cap (1), microswitch (10), spring (3), draw ring box (4), tab lever group
Part, guide pressing plate (8), draw ring bar assembly can be moved up along guide pressing plate (8)；The first end of draw ring bar assembly is mounted on draw ring
In box (4), spring (3) is sleeved on the first end of draw ring bar assembly, and spring (3) upper end is fixed on the first end of draw ring bar assembly
On, lower end is pressed in draw ring box (4) bottom, and the opening above draw ring box (4) is sealed by protection cap (1), and protection cap (1) setting turns
Axis can rotate around the axis after protection cap (1) stress, and during off working state, the upper end of the first end of draw ring bar assembly withstands on protection
It covers on (1)；The lower part of the first end of draw ring bar assembly is pierced by downwards from the hole of draw ring box (4), microswitch (10) and draw ring
The second end cooperation of bar assembly, draw ring bar assembly press microswitch (10) after moving upward to certain distance.
Preferably：Draw ring bar assembly includes tab lever (5) and draw ring guide rail (6), and tab lever (5) is the draw ring bar assembly
First end, draw ring guide rail (6) is the second end of the draw ring bar assembly, and tab lever (5) led by rivet (7) mounted on draw ring
On rail (6), rivet (7) is fixed on tab lever (5) lower end, and guide groove is set on draw ring guide rail (6), and rivet (7) is upper and lower in guide groove
It is mobile.Using tab lever (5) and draw ring guide rail (6) slidable structure, but so that total is compact, so as to save
Space.
Preferably：Further include reed (9), reed (9) is set in guide pressing plate (8), be provided on draw ring guide rail (6) with
The limit hole of reed (9) cooperation, reed (9) are pressed on draw ring guide rail (6) in off working state, are inserted in working condition
Enter in limit hole.Increase reed (9) mainly with providing feedback when draw ring bar assembly is from off working state to working condition to be made
With.
The advantages of patent of the present invention：Increase emergency extension in landing gear switch to rise and fall holder function, be lost in landing gear switch
It can ensure that undercarriage is put down safely, and simple in structure during effect, connection is reliable, and assembly technology is easy to operate.
Description of the drawings
Fig. 1 is patent structure schematic diagram of the present invention.
Fig. 2 is structure of the present invention schematic diagram when connecting model.
Specific embodiment
Fig. 1, a kind of control draw ring of shown holder function that rises and falls with emergency extension are referred to, one kind has emergency extension
Rise and fall the control draw ring of holder function, which is characterized in that including protection cap 1, microswitch 10, spring 3, draw ring box 4, tab lever group
