Description of the drawings
Fig. 1 be the utility model proposes a kind of breaker and brake separating buffer device structure diagram；
Fig. 2 be the utility model proposes a kind of breaker and brake separating buffer device A partial enlarged view.
In figure：1 housing, 2 drive links, 3 contact spring devices, 4 connecting levers, 5 briquettings, 6 telescopic rods, 7 gears, 8 fixed pins, 9 are consolidated
Determine block, 10 racks, 11 rubber blocks, 12 springs, 13 spring cases, 14 first connectors, 15 second connectors, 16 switch blocks.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of breaker and brake separating buffer device, including housing 1, housing 1 is hollow structure, and housing 1
Inside is vacuum, and the inside setting of 1 upper end of housing is fixed with drive link 2, and the lower end of drive link 2 is provided with contact spring device 3, touches
The lower end of head spring device 3 is provided with the first connector 14, the top welding of the bottom end of the first connector 14 and the second connector 15
Fixed, the first connector 14 is rubber pad buffer, and the inside of the second connector 15, which plugs, is equipped with connecting lever 4, the second connector
15 bottom end and briquetting 5 are welded and fixed, and briquetting 5 is internally provided with groove, in groove setting be fixed with hinge, one end of hinge and
One end of telescopic rod 6 is fixed, and the other end and sliding block of telescopic rod 6 are fixed, and in a groove, groove is opened in solid for sliding block setting installation
Determine the middle part of block 9, fixed block 9 and switch block 16 are welded and fixed, and one end of switch block 16 is fixed on by fixed pin 8 on housing 1, sliding block
It is fixed with gear 7, gear 7 and rack 10 engage, and one end of rack 10 and rubber block 11 are fixed, and rubber block 11 is far from rack 10
