Description
Technical field
The utility model is related to it is a kind of can main shaft interlocking Zhong Ya dual supply operations mechanism.
Background technology
Double-power supply breaker has two-way power operation mechanism, and Liang Ge power operations mechanism is linked together by centre, is
Lift the security performance of Zhong Ya dual supply operations mechanism, it is desirable to which another way power supply can not be powered after power supply is powered all the way, otherwise can
Cause circuit burnout, security incident can be caused when serious, so double-power supply breaker requires there is reliable interlocking between two-way power supply,
Another way power supply can not be powered after ensuring power supply energization all the way.
Utility model content
The technical problems to be solved in the utility model is：Overcome the deficiencies in the prior art, there is provided it is a kind of can main shaft interlocking
Zhong Ya dual supply operations mechanism, solves the defects of can not interlocking between conventional Zhong Ya dual supply operations mechanism main shaft.
Technical scheme is used by the utility model solves its technical problem：It is a kind of can main shaft interlocking middle pressure dual power supply
Operating mechanism, including upper power operation mechanism, lower power operation mechanism and middle frame, the upper power operation mechanism, lower electricity
Source operating mechanism is separately mounted to the upper and lower ends of middle frame；Power operation mechanism includes mounting bracket, spline spindle；
Upper spline spindle axis counterclockwise rotation drives upper power operation mechanism to switch on power；Lower spline spindle rotates counterclockwise band
Dong Shang power operations mechanism switches on power；
The upper spline main shaft is provided with crank, and lower spline spindle is provided with lower crank, between upper crank and lower crank
Lock shaft connecting rod is connected with, the lock shaft small end is rotatablely connected through upper pin and upper crank, and the lock shaft connecting rod lower end opens up
There is chute, the lock shaft connecting rod lower end is connected through lower bearing pin with lower crank, and the lower bearing pin passes through from chute；
The lock shaft small end is located on rear side of upper spline main shaft, before the lock shaft connecting rod lower end is located at lower spline spindle
Side；When the rotation of upper spline spindle axis counterclockwise drives upper power operation mechanism operation, upper crank handle turns lock shaft connecting rod moves upwards,
Lower bearing pin is as chute bottom.
The beneficial effects of the utility model are：Upper and lower two spline spindles are connected by lock shaft connecting rod, when one of flower
After key main shaft does combined floodgate rotation, the distance of lock shaft one chute of link motion is driven, so that lock shaft connecting rod limits another
Spline spindle rotates, it is ensured that dual supply operation mechanism only has a power sector operation all the time.

Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
As shown in Figure 1 to Figure 3, it is a kind of can main shaft interlocking Zhong Ya dual supply operations mechanism, including upper power operation mechanism
1st, lower power operation mechanism 2 and middle frame, upper power operation mechanism 1, lower power operation mechanism 2 are separately mounted to middle frame
Upper and lower ends；Power operation mechanism includes mounting bracket, spline spindle.
Upper spline main shaft 4 rotates counterclockwise the upper power operation mechanism 1 of drive and switched on power；Lower spline spindle 3 turns counterclockwise
It is dynamic to drive upper power operation mechanism 1 to switch on power.
Upper spline main shaft 4 is provided with crank, and lower spline spindle 3 is provided with lower crank, connected between upper crank and lower crank
Lock shaft connecting rod 5 is connected to, the upper end of lock shaft connecting rod 5 is rotatablely connected through upper pin and upper crank, and the lower end of lock shaft connecting rod 5 offers chute
51, the lower end of lock shaft connecting rod 5 is connected through lower bearing pin with lower crank, and lower bearing pin passes through from chute 51.The upper end of lock shaft connecting rod 5 is positioned at upper
The rear side of spline spindle 4, the lower end of lock shaft connecting rod 5 is positioned at the lower front side of spline spindle 3.
Two new middle voltage source operating mechanisms of this adaptation are operation in the same direction, i.e. two spline spindles be do it is inverse
Hour hands do combined floodgate motion when rotating；Therefore, be realize to being interlocked between two spline spindles；Between upper and lower two spline spindles
It is provided with lock shaft connecting rod 5.
In specific operation, the upper operation of power operation mechanism 1, the rotate counterclockwise of upper spline main shaft 4, lock shaft connecting rod 5 is driven
Motion upwards, makes lower bearing pin be in the bottom of chute 51, now just limits the lower operation of power operation mechanism 2, because lower power supply is grasped
To make mechanism 2 and want operation, lower spline spindle 3 must also rotate counterclockwise, but because lower bearing pin is in the bottom of chute 51, because
This lower spline spindle 3 will not also rotate, so that lower power operation mechanism 2 is in stand-by state.On the contrary, the power supply under only starting
During operating mechanism 2, lower 3 first rotate counterclockwise of spline spindle, lower bearing pin is rotated to the bottom of chute 51, and now, lock shaft connecting rod 5 will
Limitation upper spline main shaft 4 does motion of closing a floodgate counterclockwise, and Shi Shang power operations mechanism 1 is in stand-by state.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right
Property scope.
