Abstract
A kind of aircraft cockpit lock anti-mistaking locking device, this anti-error locking device comprises support, torsion spring, rotor and rotating shaft, the lock two snap close bottoms of locking at passenger cabin are provided with support, support auricle is provided with pair of holes, on support auricle, in two holes, be provided with rotating shaft, in rotating shaft, be arranged with torsion spring and rotor, torsion spring one end is fixed on support, and the other end is fixed on rotor.Portable cover is when open position, rotor upwards overturns and blocks lock bolt under the elastic force effect of torsion spring, lock bolt cannot enter on lock ring and lock in snap close, lock pull bar cannot touch air-tight switch button, when portable cover is in the closed position, lock ring ejection rotor, rotor is upset downwards around the shaft under external force, lock bolt can enter on lock ring and lock in snap close, and lock pull bar can touch air-tight switch button.This anti-error locking device, can effectively prevent from locking pull bar and touch air-tight switch button, thereby prevent the passenger cabin airtight hose swelling fracture that passenger cabin is locked by mistake and caused during in open position at portable cover.
Description
Technical field
The utility model relates to aircraft cockpit system, particularly a kind of aircraft cockpit lock anti-mistaking locking device.
Background technology
Aircraft cockpit lock system and leak-tight system link, and airtight hose is arranged on portable cover.Portable cover, when opening, is removed air-tight switch in passenger cabin if do not open, with regard in slave or the outer handle of locking of handling of machine lock, lock pull bar touches air-tight switch button, will cause passenger cabin airtight hose swelling fracture.
Summary of the invention
In order to address the above problem, the utility model provides a kind of aircraft cockpit lock anti-mistaking locking device, can be at canopy during in opening, prevent in slave or the outer error operations of the machine handle of locking is locked, make to lock pull bar and cannot touch air-tight switch button, passenger cabin airtight hose can not be inflated, thereby reaches the object that prevents passenger cabin airtight hose swelling fracture.
Passenger cabin lock comprises lock, lock ring, lock bolt and lock pull bar, lock lock is arranged on passenger cabin, lock ring is arranged on portable cover, lock bolt bolt is lock snap close and spacing buckling, lock bolt and the interlock of lock pull bar, lock pull bar and air-tight switch button interlock (not drawing in accompanying drawing), aircraft cockpit lock anti-mistaking locking device is realized by spring stop piece being set in lock two snap closes, described aircraft cockpit lock anti-mistaking locking device comprises support, torsion spring, rotor, and rotating shaft, it is characterized in that: described support is a L-type plate, on the transverse slat of bottom, have fixed orifice, riser top is provided with a pair of auricle, on auricle, have pair of holes, described rotor be one with the thin-wall part of dual side-edge, dual side-edge bottom has pair of holes, described lock two snap close bottoms are installed with described support, two snap close inner side edges on described support two auricle inner side edge alignment locks, on auricle, two centerline holes are parallel with two snap close line of centerss on lock, on auricle, in two holes, be provided with rotating shaft, in described rotating shaft, be arranged with torsion spring and rotor, described torsion spring one end is fixed on support, the other end is fixed on rotor, described rotor under the elastic force effect of torsion spring, can make progress around the shaft upset and both sides side bumper on lock two snap closes, described rotor can overturn downwards around the shaft under external force and dual-side leaves lock two snap closes.
Portable cover when open position, rotor under the elastic force effect of torsion spring upwards upset block lock bolt, lock bolt cannot enter on lock ring and lock in snap close, lock pull bar cannot touch air-tight switch button.
When portable cover is in the closed position, lock ring ejection rotor, rotor is upset downwards around the shaft under external force, and lock ring enters in the middle of lock two snap closes, and lock bolt can enter on lock ring and lock in snap close, and lock pull bar can touch air-tight switch button.
This mistake locking device is at portable cover during in open position, can effectively prevent from locking pull bar and touch air-tight switch button, thereby prevent the passenger cabin airtight hose swelling fracture that passenger cabin is locked by mistake and caused, and have simple in structure, assembling easily, reliable operation, working service be feature easily.
Accompanying drawing explanation
Fig. 1 is the utility model portable cover constructional drawing when open position;
Fig. 2 is the utility model portable cover constructional drawing when in the closed position.
In figure: 1-support, 2-torsion spring, 3-rotor, 4-rotating shaft, 5-lock, 6-lock ring, 7-lock bolt, 8-locks pull bar.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, this aircraft cockpit lock anti-mistaking locking device comprises lock [5], lock ring [6], lock bolt [7], the lock pull bar [8] that support [1], torsion spring [2], rotor [3] and rotating shaft [4] and former passenger cabin are locked.During concrete enforcement, press well above required each member of designing requirement processing and manufacturing, during installation, in the upper two snap close bottoms of lock [5], by screw, install and fix support [1], make the upper two snap close inner side edges of support [1] two auricle inner side edge alignment lock [5], and make on support [1] auricle two centerline holes parallel with two snap close line of centerss on lock, rotating shaft [4] is put to torsion spring [2], rotor [3] is also arranged on support [1] auricle in two holes, torsion spring [2] one end is fixed on support [1] simultaneously, the other end is fixed on rotor [3], guarantee rotor [3] can be under torsion spring [2] elastic force effect around the shaft [4] upwards upset and both sides side bumper on lock [5] two snap closes, finally with insuring pin in rotating shaft [4] one end, prevent that rotating shaft [4] from deviating from from shaft hole.
Portable cover is when open position, and rotor [3] upwards overturns and blocks lock bolt [7] under the elastic force effect of torsion spring [2], and lock bolt [7] cannot enter in lock ring [6] and the upper snap close of lock [5], and lock pull bar [8] cannot touch air-tight switch button.
When portable cover is in the closed position, lock ring [6] ejection rotor [3], rotor [3] around the shaft under external force [4] overturns downwards, and lock ring [6] enters in the middle of lock [5] two snap closes, lock bolt [7] can enter in lock ring [6] and the upper snap close of lock [5], and lock pull bar [8] can touch air-tight switch button.
