Strut is rotated up, this just allows stranger that can not pry open the roof door device from outside, ensure that safety.
In the present embodiment, the withstanding tight block is provided with non-slip texture close to the one side of vertical component effect.
Specific implementation process:
(1) when door be right side towards external-open when:
Step S11: the insert part 101 of mounting base 1 is inserted into 30 bottom gap of door and closes door, makes vertical component effect 102 and door 30
Outside fitting；
Step S12: rotating counterclockwise screw rod 3 by rotating handle 20 until withstanding tight block 4 is fitted in an inside, pressing tight plate 17 is bonded
In side within the walls, then stir rotation shifting block 31 downwards to the lower end of containing groove so that the occlusion teeth portion 13 of upper brake block 10 with
9 phase of ratchet part of actuator 8 is engaged；
Step S13: rotating down strut 5 by rotating lever 29, be then rotated up strut 5 again, utilizes upper brake block 10
Occlusion teeth portion 13 is engaged with 9 phase of ratchet part of actuator 8, drives 3 inverse time of screw rod by actuator 8 when strut 5 is rotated up
Needle rotation, so that withstanding tight block 4 further holds out against door-plate；
Step S14: repeating step S13, and when screw rod 3 can not rotate counterclockwise again, strut 5 rotate to the right extremely with ground
Face is parallel, and since the occlusion teeth portion 13 of upper brake block 10 is engaged with 9 phase of ratchet part of actuator 8, strut 5 can not be rotated up,
Realize roof door effect.
(2) when door be left side towards external-open when:
Step S21: screw rod 31 being removed from support base, then pins the upper end of snap-fastener 271, so that gag lever post 271 is from limit
Perforation is stretched out, then support base 2 is extracted out from mounting base 1, realizes disassembly；It is plugged again after support base 2 is turned over one side again later
1 in mounting base, screw rod 3 screws on support base 2 again；
Step S22: the insert part 101 of mounting base 1 is inserted into 30 bottom gap of door and closes door, makes vertical component effect 102 and door 30
Outside fitting；
Step S23: rotating counterclockwise screw rod 3 by rotating handle 20 until withstanding tight block 4 is fitted in an inside, pressing tight plate 17 is bonded
In side within the walls；Then rotation shifting block 31 is dialed up, so that the ratchet part 9 of the occlusion teeth portion 13 of lower brake block 11 and actuator 8
Mutually it is engaged；
Step S24: being rotated up strut 5 by rotating lever 29, then rotates strut 5 still further below, utilizes lower brake block 11

So that withstanding tight block 4 further holds out against door-plate；
Step S25: repeating step S24, and when screw rod 3 can not rotate counterclockwise again, strut 5 rotate to the left extremely with bottom
Face is parallel；
Step S26: rotation shifting block 31 is stirred downwards, so that the occlusion teeth portion 13 of lower brake block 11 and the ratchet part 9 of actuator 8 divide
From, and the occlusion teeth portion 13 of upper brake block 10 is engaged with 9 phase of ratchet part of actuator 8, so that strut 3 can not be rotated up, it is real
Existing roof door effect.
(3) when in emergency circumstances or it is flat when open the door when: shifting block 31 will be rotated and dial to the middle part of containing groove 15 so that under
Occlusion teeth portion 13 on brake block 11 or upper brake block 10 is separated with the ratchet part 9 on actuator 8, then passes through rotating lever 19
Strut 5 is turned into vertical state, finally dismantles lower screw rod and support base.
The another technical solution that the present invention uses is: a kind of working method of the roof door device suitable for outward swinging door includes
Following steps:
(1) when door be right side towards external-open when:
Step S11: the insert part of mounting base is inserted into a bottom gap and closes door, is bonded vertical component effect with outer side of door；
Step S12: rotating counterclockwise screw rod until withstanding tight block is fitted in an inside, pressing tight plate is fitted in side within the walls, then downwards
Rotation shifting block is stirred, so that the occlusion teeth portion of upper brake block is mutually engaged with the ratchet part of actuator；
Step S13: first rotating down strut, be then rotated up strut again, utilizes the occlusion teeth portion and actuator of upper brake block
Ratchet part be mutually engaged, when strut is rotated up by actuator drive screw rod rotate counterclockwise so that withstanding tight block is further
Hold out against door-plate；
Step S14: repeating step S13, and when screw rod can not rotate counterclockwise again, strut rotate to the right extremely and ground
In parallel, since strut can not be rotated up, roof door effect is realized；
(2) when door be left side towards external-open when:
Step S21: screw rod being removed from support base, removes support base from mounting base, then support base is turned over after one side again
Secondary to be plugged in mounting base, screw rod screws on support base again；
Step S22: the insert part of mounting base is inserted into a bottom gap and closes door, is bonded vertical component effect with outer side of door；
Step S23: rotating counterclockwise screw rod until withstanding tight block is fitted in an inside, pressing tight plate is fitted in side within the walls；Then upwards
Rotation shifting block is stirred, so that the occlusion teeth portion of lower brake block is mutually engaged with the ratchet part of actuator；
Step S24: being first rotated up strut, then rotate strut still further below, utilizes the occlusion teeth portion and actuator of lower brake block
Ratchet part, when strut is rotated down by actuator drive screw rod rotate counterclockwise so that withstanding tight block further holds out against door
Plate；
Step S25: repeating step S24, and when screw rod can not rotate counterclockwise again, strut rotate to the left extremely and bottom surface
It is parallel；
Step S26: stirring rotation shifting block downwards, so that the occlusion teeth portion of lower brake block is separated with the ratchet part of actuator, and on
The occlusion teeth portion of brake block is mutually engaged with the ratchet part of actuator, so that strut can not be rotated up, realizes roof door effect.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, is all covered by the present invention.
