Detailed description of the invention
As Figure 1-Figure 4, the utility model multifunctional unit shackle is locked an embodiment and is comprised pressurized strut 3 of unblanking, and this axis of unblanking pressurized strut 3 offers piston hole 31.The upper end, middle part of this piston hole 31 offers working medium input end A, and the lower end of this piston hole 31 offers working medium mouth B, and this working medium mouth B is connected to hatch door retractable actuating cylinder or undercarriage actuating cylinder, for by hatch door or gear down.This working medium is hydraulic oil or gas.In this piston hole 31, piston is set, this piston is divided into first piston body 1 independent of each other and the second piston body 9, this first piston body 1 is positioned at the rear end of this piston hole 31, and the point diameter of this first piston body 1 reduces, make to form working medium space 30 between this first piston body 1 and piston hole 31, this working medium space 30 is connected with this working medium input end A.The rear end of this first piston body 1 and the middle part of the second piston body 9 through the sealing of first and second seal ring 2,10, are leaked to avoid working medium respectively.The front end of this second piston body 9 is arranged in piston hole 31 through orienting sleeve 12, and through being threaded between this orienting sleeve 12 with piston hole 31, the inside of this orienting sleeve 12 arranges support ring 11, to realize the guiding of the second piston body 9 and spacing.This support ring 11 is provided with groove for the support of the second piston body 9, anti-attrition and exhaust.The front center of this second piston body 9 through the contact 14 that is threaded, and is fixed with nut 13, makes the overhang of contact 14 adjustable.This pressurized strut 3 bolt assembly 25 of unblanking is fixed in lock housing 24.
The rear end of this piston hole 31 arranges electric detonation gas access 32, leaves a gap 33 between this electric detonation gas access 32 and rear end of first piston body 1, with the rear end facilitating electric detonation gas to enter first piston body 1.This electric detonation gas access 32 arranges dividing plate firing unit 5 and red copper pad 4 through bolt, meets an urgent need in order to realize electric detonation.This dividing plate firing unit 5 is used as Emergency Power Supply, and the first seal ring 2 and red copper pad 4, as pressurized strut 3 and the extraneous sealing unblanked, promote the second piston body 9 and work, and when normally unblanking, first piston body 1 are failure to actuate when first piston body 1 is used as emergent.
The upside of this lock housing 24 arranges driving lever bearing pin 17, and downside arranges latch hook bearing pin 22, and the arranged outside non-return face D of this lock housing 24, the front end of this lock housing 24 arranges sensor 19.
This driving lever bearing pin 17 connects driving lever 15 through the first lining 23, this driving lever 15 is arranged the first torque spring 16 for making driving lever 15 keep inverse clock to rotate, and one end of this first torque spring 16 is connected in the first bolt 18 in lock housing 24.The contact 14 that the upper end of this driving lever 15 is arranged with the second piston body 9 front end when locking is supported mutually, and inside, the upper end of this driving lever 15 forms non-return space 35, in this non-return space 35, non-return pin 26 is set, it is spacing that one end of this non-return pin 26 arranges back-up ring 28, the other end stretches out this driving lever 15 upper end, and be arranged on the non-return pin 26 in non-return space 35 Compress Spring 27 is set, when unblanking, this driving lever 15 rotates clockwise around driving lever bearing pin 17, lock housing 24 is departed from the upper end of driving lever 15, non-return pin 26 is under the effect of Compress Spring 27, stretch out further, and be resisted against the non-return face D of lock housing 24.
This latch hook bearing pin 22 connects latch hook 20 through the second lining 23 ', and this latch hook 20 is arranged the second torque spring 29 for making latch hook 20 keep clockwise to rotate, one end of this second torque spring 29 is connected in the second bolt 18 ' in lock housing 24.When locking, the lower end of this driving lever 15 and the upper end of this latch hook 20 are supported, and snap close 34 is caught in the lower end of this latch hook 20, and an external part of this latch hook 20 supports the lower end of sensor 19.This sensor 19 is unblanked and upper lock signal for detecting, and is sent to control desk to show lock status, with being threaded between this sensor with lock housing 24.
The lock housing 24 arranged outside stopper 21 corresponding with latch hook 20 installation site, the bottom of this stopper 21 arranges and is used for carrying out snap close passage 36 that is spacing and guiding to snap close 34.
This driving lever 15 and the support surface C of latch hook 20 are the circular arc binding face waiting radius, and when upper lock position, the two circular arc binding face centers of circle overlap, and object is to ensure to unblank and lock process steady and smooth, and carrying rationally.
Utility model works principle is: as shown in Figure 1, Figure 3, and now the utility model latch mechanism is in locking state, and be not communicated with because the second piston body 9 blocks between working medium input end A and working medium mouth B, lock housing 24 is fixed on airframe.When normally unblanking, to working medium input end A voltage supply, hydraulic oil (or gas) enters the working medium space 30 of pressurized strut 3 of unblanking, second piston body 9 and contact 14 stretch out motion under the effect of the pressure, thus promotion driving lever 15 rotates clockwise, when driving lever 15 is separated completely with the circular arc binding face C of latch hook 20, latch hook 20 rotates outer year of snap close 34 and the clockwise under influence of torque spring 29, snap close 34 departs from latch hook 20, unlocking action completes, meanwhile, the non-return pin 26 be arranged in driving lever 15 ejects under the effect of pressure spring 27, and stopped by the non-return face D of lock housing 24, thus driving lever 15 cannot be resetted, guarantee that latch mechanism is reliably unblanked.After the utility model latch mechanism is unblanked, second piston body 9 is in the state of stretching out, working medium input end A is communicated with working medium mouth B, hydraulic oil (or gas) can continue to enter into hatch door retractable actuating cylinder or undercarriage actuating cylinder by hatch door or gear down, thus realizes the control of logic sequencing.
When emergent unlocking, dividing plate firing unit 5 receives emergency parachute and detonates, the impact air-flow that blast produces promotes first piston body 1 and stretch out motion together with the second piston body 9, thus promotion driving lever 15 rotates clockwise, when driving lever 15 is separated completely with the circular arc binding face C of latch hook 20, latch hook 20 snap close carry outward and torque spring 29 clockwise under influence rotate, snap close departs from latch hook, unlocking action completes, meanwhile, the non-return pin 26 be arranged in driving lever 15 ejects under the effect of spring 27, and stopped by the non-return face D of lock housing 24, thus driving lever 15 cannot be resetted, guarantee that latch mechanism is reliably unblanked.
When the utility model latch mechanism is locked, first the second piston body 9 and non-return pin 26 are pushed back original position, as the plane E of snap close 34 upwardly latch hook 20, latch hook 20 rotates around latch hook bearing pin 22 inverse clock, after latch hook 20 rotate in place, driving lever 15 is at the effect subinverse clock rotation of the first torque spring 16, and driving lever 15 is fitted with the circular arc binding face C of latch hook 20, latch hook 20 tactile sensor 19, action of locking completes.
