The bottom end of dress block 1 is fixedly connected with mounting base, and mounting base is bolted to connection on the ground, by using mounting blocks 1, peace
Tankage 2, fixed block 3, warning sign 4, card slot 5, shifting chute 6, movable block 7, the first spring 8, loose slot 9, sliding slot 10, slide bar 11,
Groove 12, link block 13, second spring 14, pull rod 15 are used cooperatively so that when warning sign 4 needs replacing, are drawn
Fixed handle, handle pull slide bar 11 to slide, and slide bar 11 pulls link block 13, link block 13 to compress second spring 14, while slide bar
11 pull pull rod 15, pull rod 15 that movable block 7 is pulled to slide, and movable block 7 compresses the first spring 8, when movable block 7 is detached from card slot 5,
Movable block 7 releases the limitation to fixed block 3, takes out warning sign 4, then replaces the warning sign 4 of needs, pushes warning sign 4, warning
Board 4 drives fixed block 3 to slide into mounting groove 2, then release handle, since the elastic force of second spring 14 itself pushes link block
13, link block 13 pushes slide bar 11 to slide, 11 pushing drawing rod 15 of slide bar, and pull rod 15 pushes movable block 7 to slide, simultaneously because first
The elastic force effect of spring 8 pushes movable block 7 to slide, and when movable block 7, which slides into, to be caught in card slot 5, movable block 7 is to fixed block 3
It is limited, completes the replacement to warning sign 4, the utility model is simple in structure, easy to use, is needing replacing in different warnings
Rong Shi meets the use demand of user convenient for the replacement to warning sign 4.
Operation principle:When warning sign 4 needs replacing, handle, handle is pulled to pull slide bar 11 in sliding slot 10
Sliding, slide bar 11 pull link block 13, link block 13 to compress second spring 14 in groove 12, make second spring 14 that shape occur
Become, while slide bar 11 pulls pull rod 15, pull rod 15 that the sliding in shifting chute 6 of movable block 7, movable block 7 is pulled to compress the first spring
8, so that the first spring 8 is deformed upon, when movable block 7 is detached from card slot 5, movable block 7 releases the limitation to fixed block 3, takes out police
Show that board 4, warning sign 4 drive fixed block 3 to skid off mounting groove 2, then replaces the warning sign 4 of needs, push warning sign 4, warning sign 4
It drives fixed block 3 to slide into mounting groove 2, stops the block 3 that is slidably installed when card slot 5 and 6 corresponding position of shifting chute, then unclamp hand
Handle, since the elastic force of second spring 14 itself pushes link block 13, link block 13 to push slide bar 11 sliding, slide bar in sliding slot 10
11 pushing drawing rods 15, pull rod 15 push the sliding in shifting chute 6 of movable block 7, simultaneously because the elastic force effect of the first spring 8 pushes
The sliding in shifting chute 6 of movable block 7, when movable block 7, which slides into, to be caught in card slot 5, movable block 7 limits fixed block 3,
The replacement to warning sign 4 is completed, the utility model is easy to operate, meets the use demand of user.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
