Trundle during work on drive mechanism is located in the stroke cavity of bevel gear, so as to the idle stroke for leaving certain is (empty herein
Stroke act as when handle goes to 90 °, and compression mechanism spring is crossed dead point and then drives drive mechanism to be rotated further, and handle
It is motionless), drive block is then provided with the outside of drive mechanism, and drive block is located in the groove of drive, therefore drive block with
Also (idle stroke is that when rotating 90 °, drive mechanism just drives drive block when handle herein idle stroke between drive
Rotate, that is, mechanism does not have torque output before spring does not reach dead point, drive block rotation is driven after crossing dead point, is accomplished
Unrelated manual operation.
Further illustrate：The compression mechanism includes guide post, spring and motion bar, the end of the guide post with it is described
Rotating shaft connects, and the motion bar is inserted in the guide post, and the spring is located between motion bar and guide post, the motion bar
Front end be connected with the drive mechanism, drive mechanism is rotated under the drive of bevel gear, at the same motion bar insertion guide post in,
So that spring-compressed, when operation handle rotates 90 °, spring crosses dead point the ability release by savings, and releasability is converted into
Drive mechanism moment of torsion promotes drive mechanism to be rotated further.
Further illustrate：The drive mechanism includes main crank and auxiliary crank, on the inside of the main crank is provided with connection
Axle, is provided with trundle in the connecting shaft, and the trundle is located in the stroke cavity in bevel gear, there is provided idle stroke.
Further illustrate：The drive mechanism both sides are provided with protrusion axle, and the drive block is located on 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 ovalize, are provided with connecting rod at the two ends of the main crank, institute
State connecting rod to be connected through the compression mechanism front end with the auxiliary crank.
Advantage of the present utility model：This utility model provides a kind of principle simply, and design of part is simple, output angle width
It is general, and manufacture experimently initial stage part easy processing, parameter adjust well by adjust idle stroke scope can just adjust output angle
Mechanism which not only improves the quality of disconnecting switch, and also reduce trial-production just meeting the demand of rotary separation switch
The difficulty of phase, allows technical staff fast and accurately determine each parameter.

Specific embodiment
This utility model is described below with reference to Figure of description.
As shown in Fig. 1 to 5-2, a kind of rotary low-pressure isolator operating mechanism, including housing 1, and be located at described
Operation handle on housing 1, wherein both sides are equipped with compression mechanism 6 before and after in the housing 1, the compression mechanism 6 is wrapped
Guide post 61, spring 63 and motion bar 64 are included, the end of the guide post 61 is connected with housing by rotating shaft 62, the motion bar
64 insert in the guide post 61, and the spring 63 is located between motion bar 64 and guide post 61, and the drive mechanism includes master
Crank 3 and auxiliary crank 7, are provided with connecting shaft 31 in the inner side of the main crank 3, and trundle 32 is provided with the connecting shaft 31,
The trundle 32 is located in the stroke cavity 51 in bevel gear 5, the main crank 3 and 7 ovalize of auxiliary crank, connecting rod 33
Positioned at the two ends of main crank 3, connecting rod 33 is connected with the auxiliary crank 7 through after the front end of motion bar 64.
Its operation principle：In an initial condition (Fig. 3-1, Fig. 3-2), the trundle 32 on main crank 3 is located on bevel gear 5
Drive block 71 on the outside of the low order end of stroke cavity 51, main crank 3 and auxiliary crank 7 also is located at 2 up groove 21 of drive block most
Right-hand member, in operating process, the rotation of operation handle drives power transmission shaft 4 to rotate, because the bottom of rotary shaft 4 is engaged with bevel gear 5,
So bevel gear 5 is by synchronous axial system, now because the trundle 32 on main crank 3 is located at the low order end of stroke cavity 51,
The rotation of bevel gear 5 can drive main crank 3 and auxiliary crank 7 to rotate immediately, simultaneously because drive block 71 is most right positioned at row groove 21
End, so now main crank 3 and auxiliary crank 7 can't drive drive 2 to rotate, in the process as main crank 3 is bent with pair
The distance between the rotation of handle 7, motion bar 64 and guide post 61 shorten, and spring 63 is compressed, when 7 degree of main crank 3 and auxiliary crank
After crossing horizontal level (Fig. 4-1, Fig. 4-2), drive block 71 also is moved into the high order end of row groove 21, and now (now handle is just
It is rotated by 90 °) avoid the need for being rotated further by operation handle, the spring 63 under compressive state is crossed dead point and is released energy before, from
And promote main crank 3 and auxiliary crank 7 to be rotated further, in the process, because the presence of stroke cavity 51, trundle 32 will
Move in stroke cavity 51, such bevel gear 5 would not hinder the rotation of main crank 3, and the biography of main crank 3 and auxiliary crank 7
Motion block is located at 2 21 leftmost side of cavity, therefore drive block 71 will drive drive 2 to rotate, and final power is passed by drive 2
Pass away.
