End connection self-locking device；
Bearing 5, one end is connected on self-locking device, and the other end and hatch door mouthful frame eyebrow beam 1 are affixed, play fixed supporting role；
Pull bar 10, one end is connected on self-locking device, other end connection hatch door；
Self-locking device, distinguishes connects bearing 5, the gentle spring 3 of pull bar 10, thereon the locking member 6 with mutual cooperation and gear
Block 12, when hatch door is opened and is in final state, the block 12 is locked with the locking member 6 being connected on bearing 5.
As Figure 4-Figure 7, the self-locking device includes：
Shown, connecting crank 4 is triangular frame structure, and one jiao of end is connected on two gas springs, and the angle end carries two points
Not Lian Jie gas spring 3 adapter sleeve hole, be sleeved on gas spring 3；One jiao of end cylinder lever connecting rod 10, the angle end is with connection bearing pin 13
Two connecting holes, pull bar 10 is placed between two connecting holes, connected by bearing pin 13；Another angle end connection rotating shaft 7, the angle end is with company
Switch through the mounting hole of axle 7, bearing 5 is nested with the rotating shaft 7, positioned at the outside of connecting crank 4, the connecting crank 4 close to the end of rotating shaft 7
Outward flange carries block 12；Connecting crank 4 keeps contacting with locking member 6 in unlocked timing instant, and connecting crank 4 is to locking member
6 opposition F1 and both contact points are more than 30 ° with sharp angle α folded by the line of centres of lock shaft 9, it is ensured that hatch door opening or
Stuck situation will not occur in closing process.
As shown in Fig. 2, Fig. 7, locking member 6 on lock shaft 9, between connecting crank 4 and bearing 5, is opening cabin
During 7 rotation around the shaft of door connecting crank 4, locking member 6 is slided along the surface of connecting crank 4, when hatch door is opened and is in final state,
Locking member 6 is just locked with the block 12 on connecting crank 4, realizes self-locking.In the locked state, the termination of locking member 6 with
Maximal clearance between the block 12 of connecting crank 4 is 1mm -2mm；When resilience occurs for gas spring 3, locking member 6 and connecting crank
4 block 12 is contacted, directed force F 2 and the angle β of both contact points and lock shaft 9 line of centres of the connecting crank 4 to locking member 6
