Summary of the invention
Problem to be solved in the utility model: convenience problem when circuit breaker mounts and dismounts on power distribution cabinet.
For solving the problem, the scheme that the utility model adopts is as follows:
A Quick disassembling structure for breaker of plastic casing, comprises circuit breaker and deck; Described deck comprises base plate and two wiring Connection Blocks; Two wiring Connection Blocks are arranged on the two ends up and down of base plate respectively; Circuit breaker screens space is formed between two wiring Connection Blocks; The two ends up and down of circuit breaker are provided with binding post; Wiring Connection Block is provided with terminal groove; Circuit breaker is placed in described circuit breaker screens space; Binding post is bolted in the terminal groove of wiring Connection Block.
Further, the two ends up and down of circuit breaker are also provided with convex; The inner side of wiring Connection Block is also provided with post groove; Convex is stuck in post groove.
Further, the left and right sides of circuit breaker is also provided with snak link; Base plate is also provided with fixture block; Snak link is buckled on fixture block.
Further, snak link comprises buckle; The side plate bottom of circuit breaker is provided with catching groove; Buckle is arranged in catching groove by buckle axle; Buckle axle is positioned at the middle part of buckle, and the top being positioned at buckle axle is provided with spring; The two ends of spring are connected with buckle with side plate respectively; The below of buckle is provided with button bit; Button bit is stuck on fixture block.
Further, described deck also comprises binding post cover; Binding post cover is buckled on wiring Connection Block by the buckle of wiring Connection Block both sides.
Technique effect of the present utility model is as follows: when the utility model uses, the base plate of deck is mounted and fixed in power distribution cabinet, and on power distribution cabinet, winding displacement is also fixed in the pilot trench of wiring Connection Block upper end accordingly.When circuit breaker is installed, only need circuit breaker to be inserted in the circuit breaker screens space between upper and lower wiring Connection Block, in the terminal groove then 8 binding posts up and down of circuit breaker being screwed in wiring Connection Block, namely complete installation.To be coordinated by clamping mechanism each other between circuit breaker and deck and screw on binding post is fixed.Compared to existing structure, the utility model when mounted, only needs a stubborn screw; During dismounting, also only need a stubborn screw; Operating time when greatly reducing installation and removal and workload.
