It can cause false triggering, and it is more reliable with the microswitch of contact 3.When bulb 1 will enter ball-and-socket 2, retaining mechanism is needed
It to be in free state, foldable handle 10 is rotated at this time and is pushed up at this time so that claw 11 is stuck at 16 maximum gauge of variable diameter boss
First 13 is farthest from center, and bulb 1 be free to enter ball-and-socket 2, meanwhile, the side protrusion 20 of variable diameter guide rail 5 triggers first
A microswitch 3, the warning light that the expression retaining mechanism that microswitch 3 controls is in free state light.When adjustment aircraft portion
When part posture, it is desirable to which bulb 1 can have certain amount of exercise, but cannot deviate from ball-and-socket 2, and retaining mechanism is needed in anti-
Escape state rotates foldable handle 10 at this time and comes directly towards at 13 at this time so that claw 11 is stuck at 16 mid diameter of variable diameter boss
In middle position, bulb 1 can rotate in a certain range, but cannot deviate from ball-and-socket 2, meanwhile, the side protrusion of variable diameter guide rail 5
20 trigger second microswitch 3, and the warning light that the expression retaining mechanism that microswitch 3 controls is in anti-escape state is bright
It rises.When adjusting aircraft components docking or processing, it is desirable to which bulb 1 is completely fixed motionless, retaining mechanism relative to locator
It needs foldable handle 10 to be rotated at this time, so that claw 11 is stuck at 16 minimum diameter of variable diameter boss, at this time in locking state
Top 13 is in the position nearest from center, has been pressed on bulb 1, and bulb 1 is fixed completely, meanwhile, the side of variable diameter guide rail 5
Protrusion 20 triggers third microswitch 3, and the warning light that the expression retaining mechanism that microswitch 3 controls is in locking state is bright
It rises.Each warning light rolls over dynamic foldable handle 10 after lighting down, is pressed into handle holing clip 8, and check warning light whether according to
Right correct light yellow, again pulls up foldable handle 10 when per secondary rotation variable diameter guide rail 5.The present apparatus has triple protection, first is that
It is all operation be all it is mechanical, there is no the influences of electric fault；But institute it is stateful have corresponding light prompt, into one
Step is guaranteed at correct status；It accidentally bumps against and can roll over third is that the handle holing clip 8 being fixed on ball-and-socket protective case 4 can prevent worker
Folded handle 10, changes the state of retaining mechanism.In addition, the idler wheel 19 and arc-shaped guide rail 9 on claw 11 are but also fluent motion
It is feasible, and wear small.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.In the absence of conflict, the spy in embodiments herein and embodiment
Sign can be arbitrarily combined with each other.
