The bottom side of the wall of mounting shell 7 offers opening 807, and flare is blown drawstring 809 into mounting shell 7 by being open to alter,
And opening 807 is located at the top of battery group 2 and is arranged, be open 807 side wall it is fixed there are two annulus 808, and two annulus 808
It is connect respectively by drawstring 809 with bull stick 803, drawstring 809 uses cotton material, it is ensured that can quickly be blown by fire, in drawstring 809
After being blown, briquetting 806 falls under gravity, and the switch that briquetting 806 pushes down fire extinguisher 5 makes its opening, due to bull stick
803 are rotatablely connected with the first column 801 and the second column 805 respectively by first rotating shaft 802 and the second shaft 804, Er Qie
Two columns 805 run through the side wall of mounting shell 7, therefore the lower movement in the vertical direction of briquetting 806, it is ensured that can suppress fire extinguisher 5
Switch.
Battery group 2 of the invention is fixed in mounting base 1, after fire extinguisher 5 is placed in placing groove 302, is inwardly pushed away
Dynamic push rod 403, gag lever post 405 are separated with the limit hole 406 on disk 308, and threaded rod 305 can be rotated at this time, are rotated clockwise
Threaded rod 305, the power that screws between threaded rod 305 and thread bush 304 pushes up threaded rod 305 to fire extinguisher 5, and then makes the second folder
It holds block 307 to push up fire extinguisher 5 to the first grip block 303, since the second grip block 307 passes through rotating member 306 and 305 turns of threaded rod
Dynamic connection, therefore when threaded rod 305 rotates, axial turn no longer occurs for the second grip block 307 to offset with fire extinguisher 5
Dynamic, such first grip block 303 and the second grip block 307 resist fire extinguisher 5, so that fire extinguisher 5 is fixed on placing groove 302
In, after fire extinguisher 5 has been fixed, unclamp push rod 403, the elastic force of the first spring 402 is by 405 bullet of gag lever post into limit hole
In 406, threaded rod 305 to be fixed, prevent threaded rod 305 from turning round the fixed relaxation caused to fire extinguisher 5, and when needs
It is same first inwardly to push push rod 403 when replacing fire extinguisher 5, separate gag lever post 405 with limit hole 406, then rotate counterclockwise spiral shell
Rasp bar 305 makes the second grip block 307 far from fire extinguisher 5 so that it is convenient to which fire extinguisher 5 is taken out from placing groove 302.
When battery group 2 is burnt, the flare of upward play is entered in mounting shell 7 by opening 807 burns drawstring 809
Disconnected, one end of bull stick 803 loses limitation, and briquetting 806 falls under gravity, and the switch that briquetting 806 pushes down fire extinguisher 5 makes
It is opened, and fire extinguisher 5 puts out a fire to battery group 2, in order to avoid cause the burning of entire car body, and the bolt on fire extinguisher 5 shifts to an earlier date
It has pulled.
The cover board 11 on installation window 9 is opened, can facilitate and bull stick 803 and annulus 808 are connected to one with new drawstring 809
It rises, one end of drawstring 809 ties up on annulus 808, and the other end ties up on bull stick 803, when opening cover board 11, first pulls out riser
15, fixture block 16 is separated with card slot 17, and cover board 11 can be raised, while second spring 13 is stretched and is provided with elastic force, is covered when closing
After plate 11, riser 15 is unclamped, the elastic force of second spring 13, which pops into position riser 15, to be set, and fixture block 16 is sticked into again in card slot 17,
Cover board 11 is fixed on installation window 9.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
