Abstract
The invention belongs to airplane equipment design field, and in particular to a kind of engine overrun indicates Resetting Switching protection device.Existing engine overrun indicates Resetting Switching unprotect device, exposed to outer, easy maloperation and cause engine overrun record to disappear, thus the excess revolutions record of engine may be influenceed, and then influence the maintaining of engine.The engine overrun instruction Resetting Switching protection device of the present invention, installed in the outside of the installing plate, including the screw of the protection cap of locking string holes and locking string holes, one end of the protection cap is rotatably mounted on the installing plate, and the other end has locking wire hole.Effective protection to engine overrun instruction Resetting Switching, the influence for avoiding artificial maloperation from recording equipment can be realized.
Description
Technical field
The invention belongs to airplane equipment design field, and in particular to a kind of engine overrun instruction Resetting Switching protection dress
Put.
Background technology
Existing engine overrun indicates Resetting Switching unprotect device, exposed to outer, easy maloperation and cause to start
Machine excess revolutions record disappears, thus may influence the excess revolutions record of engine, and then influences the maintaining of engine, such as Fig. 1 institutes
Show.
The content of the invention
The present invention provides a kind of engine overrun instruction Resetting Switching protection device, it is possible to achieve engine overrun is indicated
Effective protection of Resetting Switching, the influence for avoiding artificial maloperation from recording equipment.
The engine overrun of the present invention indicates Resetting Switching protection device, and being provided with engine overrun on the inside of installing plate refers to
Showing Resetting Switching, the device is arranged on the outside of the installing plate, including the screw of the protection cap of locking string holes and locking string holes,
One end of the protection cap is rotatably mounted on the installing plate, and the other end has locking wire hole, when protection cap is rotated to protection
During position, two locking wire hole alignment and lockable.
Protection cap end has hole, is rotatably mounted by screw rod and nut.
The screw is combined fixation with nut.
The protection cap is to protect hiding engine overrun instruction Resetting Switching, during locking, using locking wire or silk thread
Fixed through relative locking wire hole.
When needing to use engine overrun instruction Resetting Switching, the locking wire tied up is released, rotation protection cap to engine surpasses
Turn instruction Resetting Switching fully to expose.
Beneficial effect：The present invention can realize effective protection to engine overrun instruction Resetting Switching, avoid artificial miss
Operate the influence to equipment record.
