Description
Technical field
The present invention relates to a kind of isolator operating mechanisms, especially rotary low-pressure isolator operating mechanism.
Background technique
The conventional low disconnecting switch movable contact direction of motion is lateral, that is to say, that contact supporter drives movable contact to do
Horizontal movement, so operating mechanism need to only provide the thrust an of transverse direction or pulling force and can make to switch divide-shut brake, we claim this
Mode is sliding, but with the gradually development of low voltage isolation switch, low tension switch is mainly revolving at this stage, that is,
Contact supporter drives movable contact to do using contact supporter center as the circular motion in the center of circle, rotatably keeps apart for existing
Pass has the following disadvantages: 1, existing rotary separation switch operating mechanism is since structure limits in the market, output angle
It is limited；2, the element precision in disconnecting switch is more demanding, therefore the complexity that processing technology also becomes, and which not only improves keep apart
The production cost of pass, and also add the difficulty of research and development initial stage exemplar trial-production.
Summary of the invention
Technical assignment of the invention is to be directed to the above the deficiencies in the prior art, and provide a kind of rotary low-pressure disconnecting switch
Operating mechanism.
The technical solution adopted by the present invention to solve the technical problems is: a kind of rotary low-pressure isolator operation machine
Structure, including shell, and the operation handle on the shell, wherein being equipped with compression in the intracorporal front and rear sides of the shell
The end of mechanism, the compression mechanism is connect by shaft with the shell, is equipped with biography in the intracorporal left and right sides of the shell
Motivation structure, the transmission mechanism are connect with the front end of the compression mechanism, bevel gear are equipped between transmission mechanism, in the cone
Gear is equipped with stroke cavity, and the transmission mechanism is connect by trundle with bevel gear, and transmission is equipped on the outside of transmission mechanism
Wheel, is equipped with groove on the driving wheel, and transmission mechanism is connect with driving wheel by drive block, connected above the bevel gear
It is connected to transmission shaft, the bottom of the transmission shaft is engaged with the bevel gear, and top is connect with the operation handle, in whole operation
The trundle on transmission mechanism is located in the stroke cavity of bevel gear in the process, so that there are certain idle stroke (nulls herein
The effect of journey is when handle goes to 90 °, and compression mechanism spring crosses dead point and then transmission mechanism is driven to continue to rotate, and handle is not
It is dynamic), drive block is then equipped on the outside of transmission mechanism, and drive block is located in the groove of driving wheel, therefore in drive block and passes
Also playing the role of idle stroke between driving wheel, (idle stroke is that when rotating 90 °, transmission mechanism just drives drive block to turn when handle herein
It is dynamic, that is, spring do not reach dead point before mechanism there is no torque output, drive drive block rotation after crossing dead point, accomplished nothing
Close manual operation.
Further illustrate: the compression mechanism includes guide rod, spring and motion bar, the end of the guide rod with it is described
Shaft connection, the motion bar are inserted into the guide rod, and the spring is between motion bar and guide rod, the motion bar
Front end connect with the transmission mechanism, transmission mechanism rotates under the drive of bevel gear, at the same motion bar insertion guide rod in,
So that spring-compressed, when operation handle rotates 90 °, spring crosses dead point and discharges the ability of savings, and releasability is converted into
Transmission mechanism torque pushes transmission mechanism to continue to rotate.
Further illustrate: the transmission mechanism includes main crank and auxiliary crank, is equipped with connection in the inside of the main crank
Axis is equipped with trundle in the connecting shaft, and the trundle is located in the stroke cavity in bevel gear, provides idle stroke.
Further illustrate: the transmission mechanism two sides are equipped with protrusion axle, and the drive block is located in the protrusion axle, described
Drive block is located in the groove, and idle stroke is formed between drive block and groove.
Further illustrate: the main crank and auxiliary crank are oval, are equipped with connecting rod, institute at the both ends of the main crank
Connecting rod is stated to connect across the compression mechanism front end with the auxiliary crank.
Advantages of the present invention: the present invention provides a kind of principle is simple, design of part is simple, and output angle is wide in range, and
Trial-production initial stage part easy processing, parameter, which adjust well the range by adjusting idle stroke, can adjust the mechanism of output angle to expire
The demand of sufficient rotary separation switch, which not only improves the qualities of disconnecting switch, and also reduce the difficulty at trial-production initial stage,
Allow technical staff that can fast and accurately determine each parameter.

Specific embodiment
The present invention is described below with reference to the accompanying drawings of the specification.
As shown in Figs. 1-5, a kind of rotary low-pressure isolator operating mechanism, including shell 1, and it is located at the shell
Operation handle on 1, wherein the front and rear sides in the shell 1 are equipped with compression mechanism 6, the compression mechanism 6 includes leading
To bar 61, spring 63 and motion bar 64, the end of the guide rod 61 is connect by shaft 62 with shell, and the motion bar 64 is inserted
Enter in the guide rod 61, for the spring 63 between motion bar 64 and guide rod 61, the transmission mechanism includes main crank 3
With auxiliary crank 7, it is equipped with connecting shaft 31 in the inside of the main crank 3, trundle 32, the biography are equipped in the connecting shaft 31
Dynamic pin 32 is located in the stroke cavity 51 in bevel gear 5, and the main crank 3 and auxiliary crank 7 are oval, and connecting rod 33 is located at master
The both ends of crank 3, connecting rod 33 are connect behind the front end of motion bar 64 with the auxiliary crank 7.
Its working principle: (Fig. 3) in the initial state, the trundle 32 on main crank 3 are located at 5 up stroke cavity of bevel gear
The drive block 71 of 51 right end, 7 outside of main crank 3 and auxiliary crank also is located at the right end of 2 uplink groove 21 of drive block, operation
In the process, the rotation of operation handle drives transmission shaft 4 to rotate, because the bottom of rotation axis 4 is engaged with bevel gear 5, bores tooth
Wheel 5 will rotate synchronously, at this time because the trundle 32 on main crank 3 is located at the right end of stroke cavity 51, bevel gear 5
Rotation can drive immediately main crank 3 and auxiliary crank 7 to rotate, simultaneously because drive block 71 is located at 21 right end of row groove, so this
When main crank 3 and auxiliary crank 7 not will drive the rotation of driving wheel 2, in the process with the rotation of main crank 3 and auxiliary crank 7,
The distance between motion bar 64 and guide rod 61 shorten, and spring 63 is compressed, when main crank 3 and auxiliary crank 7 spend horizontal position
(Fig. 4) afterwards, drive block 71 also are moved into the left end of row groove 21, at this time (handle is just rotated by 90 ° at this time) there is no need to again
Operation handle is rotated, the spring 63 under compressive state crosses dead point and releases energy before, to push main crank 3 and pair bent
Handle 7 continues to rotate, and in the process, because of the presence of stroke cavity 51, trundle 32 will move in stroke cavity 51,
Bevel gear 5 in this way would not hinder the rotation of main crank 3, and to be located at cavity 2 21 most left for the drive block of main crank 3 and auxiliary crank 7
Side, therefore drive block 71 will will drive driving wheel 2 and rotate, final power is passed by driving wheel 2.
