Description
Technical field
The present invention relates to power supplying and distributing equipment accessory technical fields, and in particular to a kind of power distribution cabinet New Low Voltage breaker of plastic casing
Operating mechanism.
Background technique
Electric product exhibition and electric appliance in the market, low-voltage circuit breaker be seen everywhere, especially mold cased circuit breaker by
Favor.Two sections of defencive functions that mold cased circuit breaker has overload long delay, short-circuit wink dynamic, can also be with Electrical leakage, measurement, electricity
The modular units such as behaviour are used cooperatively.In low-voltage distribution system, commonly uses it and do terminal switch or branch switch, it is normal instead of the past
Fuse and knife switch.
Chinese patent 201410317219.4 discloses a kind of low-voltage distribution cabinet drawer operation interlocking mechanism.The mechanism includes
The fixed frame being fixedly installed in above drawer-bottom board is equipped with the open circuit for killer switch to be opened or closed on fixed frame
Device operating mechanism, the drawer interlocking for making drawer unlock when killer switch disconnects or be latched in killer switch closure
Mechanism and be fixedly connected between circuit breaker operation mechanism and drawer interlocking mechanism be used to and meanwhile drive breaker operator machine
The drive shaft of structure and drawer interlocking mechanism movement, drive shaft are arranged between fixed frame, and head end is placed on the outside of fixed frame, tail
Portion end is fixedly connected with circuit breaker operation mechanism, drawer interlocking mechanism be fixedly connected on drive shaft head end and aft end it
Between.
But above-mentioned patent there is a problem, as conventional electrical distribution cabinet power distribution unit (each drawer loop) each plastic housing is disconnected
Road type number will assemble a kind of special-purpose assorted operating mechanism, thousands of kinds of model breaker of plastic casing in this way because of outer dimension difference,
Switch over travel difference, it is necessary to which thousands of kinds of operating mechanism models are mating, thus cause the producer that manufacture produces the product, nothing
Method forms scale and produces in enormous quantities, and causes confusion to management and product inventory is largely caused to overstock, and give using producer because of type
Number various easy type selecting error, and cannot exchange and form accessory and largely waste and improve cost, etc..
Summary of the invention
The present invention in view of the above-mentioned problems, to provide a kind of structure simple, easy to use there is mounting structural mode to have overturned biography
The mode of system installation on-board the circuit breaker, a kind of operating mechanism will specially be matched by solving each breaker of plastic casing model of each manufacturer
Limitation operating mechanism.
Technical solution used by the present invention solves the above problems is:
A kind of operating mechanism of power distribution cabinet New Low Voltage breaker of plastic casing, including fixed bracket, the fixed bracket two sides
Equipped with mounting plate；Shell, the shell are fixed on fixed bracket, and cavity is equipped in the shell, is set in the cavity
There is operating mechanism.
Further, operating mechanism includes the slide bar being fixed in cavity, and sliding block, the slide bar two are cased on the slide bar
End is designed with reset spring, and the slip front is equipped with locating piece, and the locating piece is equipped with boom device.
The size design of adaptation switch that can be bigger by the design of sliding block, reset spring can fit after allowing switch to break the limit
Elastic recoil is answered, is given and is sold square shaft and can adjust back positive position, makes switch operation more humane.
Further, the boom device includes the axle sleeve of setting on the shell, and the axle sleeve rear end is equipped with pivoted arm, institute
It states and is equipped with sliding slot in pivoted arm, the locating piece is movably arranged in sliding slot.
Further, the axle sleeve front end is equipped with axis hole, is equipped with tooth form square hole in the axis hole, on the tooth form square hole
Equipped with square shaft.
It allows operating mechanism that can be applicable in more switches by the design of tooth form square hole, while ajusting square shaft direction, not by original
Square hole, which limits back, makes switch angle crooked.
Further, limit fixed plate is additionally provided on the square shaft, the limit fixed plate is L shape, and the limit is solid
Fixed board one end is fixed on fixed bracket, and the square shaft passes through limit fixed plate.
By limiting fixed plate, allows square shaft by axle sleeve and limit fixed plate and be fixed on operating mechanism, allow the making of square shaft
It can be increased significantly with length.
Further, cover board is additionally provided on rear side of the shell, the cover board is equipped with hollow-out parts.
The invention has the advantages that
1. the configuration of the present invention is simple, handling ease, low in cost；
2. each production due to the technical requirements (being horizontal direction and vertical direction when switch division) to operating mechanism
The breaker trip of producer's production has minor differences, and by improving the design of axis hole, changing original square is multiple tooth shape, in this way
It solves since each switch over travel is different, and connecting rod is caused to connect with handle not 90 degree of positions；
3. in order to meet each shelves current specification of low-pressure plastic shell circuit breaker, operating mechanism is divided into 3 models, A grades
Thousands of kinds of models, it is general to be changed to 3 kinds of models by (630A-800A), B grades (250A-400A) and C grades (63A-125A).It mentions significantly
High production scale standardization, it is puzzled to relieve user's type selecting, and exchange easy to repair；
4. present invention manufacture is easy, easy to assembly, stable structure is durable.
Other than objects, features and advantages described above, there are also other objects, features and advantages by the present invention.
Below with reference to figure, the present invention is described in further detail.
