And backing plate, wherein bracket is mounted on airframe structure, and jacking block is sleeved on the pull rod of lock system and can slide along pull rod, airtight
Switch is fixed on bracket by backing plate；Multiple mounting holes are provided on backing plate, it is opposite for adjusting air-tight switch vertical direction
Position.
In the present invention, the connection bolt for adjusting air-tight switch relative position is provided on bracket.
In the present invention, it is separately provided for adjusting the connection spiral shell of air-tight switch relative position on air-tight switch and backing plate
Bolt.
In the present invention, backing plate is tooth form backing plate.
In the present invention, the toothed surface with backing plate mutual cooperation adjusting position is provided on air-tight switch.
In the present invention, fastening screw nut is respectively arranged on the pull rod for being located at jacking block both ends.
In the present invention, the gasket for adjusting jacking block and air-tight switch upper ejector pin deviation to the right is provided on backing plate.
In the present invention, the gasket for adjusting jacking block and air-tight switch upper ejector pin deviation to the right is provided on bracket.
In the present invention, after the locking in place of canopy latch mechanism, jacking block is moved along pull rod, by the mandril pressure of air-tight switch
Under, leak-tight system is connected, to enable the relative position of air-tight switch and jacking block to guarantee that the two is normal in locking and unlocking
Dynamic, the mandril volume under pressure and mandril of air-tight switch should all match in the position of jacking block contact plane with interaction relation；Work as gas
When close switch mandril volume under pressure exceeds normal range value, unscrew the connection bolt of connection air-tight switch, tooth form backing plate and bracket, it will
Until air-tight switch up and down adjustment to satisfaction；When there are deviation in air-tight switch and jacking block course relative position, unscrew and press closer block
On two fastening screw nuts, jacking block is free to slide on pull rod at this time, so as to adjust the rigging position of jacking block；When jacking block with it is airtight
Mandril on switch to the right deviation when, pass through and increase gasket on tooth form backing plate and bracket and adjust.
The utility model has the advantages that the present invention adjusts the tooth form backing plate of air-tight switch vertical direction relative position by setting and adjusts gas
The jacking block of relative position between close switch and canopy latch mechanism, enable vector and vertical direction, it is lateral it is upper from
By adjusting, it is effectively improved assembly process process, reduces assembly positioning difficulty.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of presently preferred embodiments of the present invention.
Fig. 2 is jacking block in the presently preferred embodiments of the present invention scheme of installation on pull rod.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
Referring to a kind of linkage adjustment mechanism for canopy latch mechanism and leak-tight system of FIG. 1 to FIG. 2, including bracket 1,
Jacking block 2, fastening screw nut 3, pull rod 4, air-tight switch 5 and tooth form backing plate 6, wherein bracket 1 is mounted on airframe structure, lock system
Pull rod 4 penetrate through jacking block 2 and stretch out jacking block 2, and be provided with fastening screw nut 3 on the pull rod 4 for being located at 2 both ends of jacking block, it is airtight to open
5 are closed to be fixed on bracket 1 by tooth form backing plate 6；It is provided with multiple mounting holes on tooth form backing plate 6, hangs down for adjusting air-tight switch 5
Histogram is to relative position；
The connection bolt for adjusting 5 relative position of air-tight switch is provided on bracket 1；
After the locking in place of canopy latch mechanism, jacking block 2 is moved along pull rod 4, and the mandril of air-tight switch 5 is depressed, and leak-tight system connects
It is logical, to enable the relative position of air-tight switch 5 and jacking block 2 to guarantee normal linkage of the two in locking and unlocking, air-tight switch 5
