Specific embodiment
Referring to figs. 1 to Fig. 4 it is found that the utility model: a kind of breaker of field-replaceable unit, including 1 He of breaker body
Control switch 2, it is characterised in that: the control switch 2 includes switch knob 3 and shaft 4, and the shaft 4 is equipped with groove 5,
5 inner wall of groove is equipped with the blind hole I 6 being connected with groove 5, and the blind hole I 6 is interior convex equipped with being connected by spring 7
Block 8, the switch knob 3 is equipped with the raised line 9 being adapted to groove 5, convex block 9 and groove 5 and convex block 8 cooperates, and makes switch knob 3
An entirety is formed with shaft 4；It is equipped with the blind hole II 10 matched with convex block 8 at 9 center of raised line, is set in the shaft 4
There are control block 11 and sliding slot 12, the sliding slot 12 is connected to blind hole I 6, and the two connection keeps 8 model- following control block 11 of convex block sliding
It moves；The control block 11 passes through the link block 13 being arranged in sliding slot 12 and connects convex block 8；
Cover board 14 is additionally provided in the sliding slot 12, the cover board 14 is equipped with arc groove 15, and arc groove 15 makes to open
Cover board 14 is more convenient；The cover board 14 and shaft 4 are hinged.
The switch knob 3 is dies setting.
Rubber seal ring is equipped between the cover board 14 and sliding slot 12, rubber seal ring is fixed on cover board 14, and rubber is close
Seal ring is bonded cover board 14 with sliding slot 12 closely, good waterproof performance.
Specific working principle are as follows:
Firstly, disassembly switch knob 3 when, open cover board 14, by control block 11 along the chute 12 away from groove 5 direction
Sliding, and drive convex block 8 to move into blind hole I 6 using link block 13；Switch knob 3 is extracted out of shaft 4, switch knob
3 disassemblies are completed.
When replacing switch knob 3, above-mentioned movement is repeated, opens cover board 14, sliding control block 11 makes convex block 8 put in blind hole I
In 6；Raised line 9 on switch knob 3 is filled in groove 5, and blind hole II 10 is made to be directed at blind hole I 6；Control block 11 is decontroled, it is convex
Block 8 is fixed on switch knob 3 in shaft 4 by the elastic force effect return and jacking blind hole II 10 of spring 7.Cover cover board
14, replacement switch knob 3 is completed.
The utility model effectively improves the problem of control switch is vulnerable to damage, the breaker knot of the field-replaceable unit
Structure design is rationally simple, and the position of the fixed switch knob 3 of convex block 8 prevents from skidding off groove 5, firm stable；The replacement behaviour of switch knob 3
Make simple；Cover board 14 protects sliding slot 12 internally dry clean.
Every technical staff's notice: although the utility model is described according to above-mentioned specific embodiment, this
The invention thought of utility model is not limited to that utility model, and any repacking with inventive concept will all be included in this specially
In sharp scope of patent protection.
