Embodiment
A kind of operating means of isolating switch, comprise clamp assembly and be connected to the operating grip on clamp assembly, described clamp assembly comprises threaded rod, the nut coordinating with described threaded rod, along the axially movable lower fixture block of described threaded rod, along the axially movable upper fixture block of described threaded rod, Antiskid screw, described lower fixture block and described upper fixture block amalgamation form clamping slot, described Antiskid screw one end extends in clamping slot through described lower fixture block or described upper fixture block, described nut by rotating on threaded rod, regulate the relative distance between described upper fixture block and described lower fixture block.
Concrete structure of the present invention, as depicted in figs. 1 and 2, the operating means of isolating switch comprises operating grip 1, lower fixture block 2, upper fixture block 3, Antiskid screw 4 and threaded rod 5, and institute's Antiskid screw of telling 4 is hex(agonal)screw, and described threaded rod 5 is bolt.Lower fixture block 2 is provided with groove 21, location hole 22, screwed hole 23, screwed hole 24, screwed hole 25 and screwed hole 26, one end of operating grip 1 is provided with connecting rod 11, connecting rod 11 is through location hole 22, upper fixture block 3 is provided with groove 31, tapped through hole 32, through hole 33, through hole 34, through hole 35 and through hole 36, Antiskid screw 4 is through tapped through hole 32, threaded rod 5 coordinates with nut through through hole 33 and through hole 23, threaded rod 5 coordinates with nut through through hole 34 and through hole 24, threaded rod 5 coordinates with nut through through hole 35 and through hole 25, threaded rod 5 coordinates with nut through through hole 36 and through hole 26, described clamping slot is made up of groove 21 and groove 31.As shown in Figure 4, groove 21 is provided with between 27, two different anti-skidding boss 27 of anti-skidding boss and is provided with channel of chip removal 28.As shown in Figure 3, groove 31 is provided with between 37, two anti-skidding boss 37 of anti-skidding boss and is provided with channel of chip removal 38.
When operating means work, lower fixture block 2 contacts with isolating switch by the anti-skidding boss 27 in groove 21, upper fixture block 3 contacts with isolating switch by the anti-skidding boss 37 on groove 31, threaded rod 5 is through after upper fixture block 3 and lower fixture block 2, rotate on threaded rod 5 by nut, thereby isolating switch is clamped in groove 21 and groove 31, and anti-skidding boss 27 and anti-skidding boss 37 withstand isolating switch.Meanwhile, in the time that operating means is worked, Antiskid screw 4 rotates to groove 31 on tapped through hole 32, further fixes isolating switch thereby withstand isolating switch.Operating grip 1 drives clamp assembly along the rotation of isolating switch axis, realizes the object that changes isolating switch operating state.
In the present embodiment, through hole 23, through hole 24, through hole 25 and through hole 26 are set on lower fixture block 2, but, under reality is manufactured when fixture block 2, four screwed holes can be set on lower fixture block 2, coordinate through hole 23, through hole 24, through hole 25 and the through hole 26 of fixture block 3, then by the screw thread of the one end at threaded rod 5, thereby isolating switch is fixed between upper fixture block 3 and lower fixture block 2.
In the present embodiment, in groove 21, be provided with ten highly consistent anti-skidding boss 27, in groove 31, be provided with ten highly consistent anti-skidding boss 37.But in reality is manufactured, the inner surface of clamping slot is provided with the consistent anti-skidding boss of two tile heights, then coordinating Antiskid screw 4, by the mode of similar scroll chuck, just can realize the object of fixing isolating switch, certainly, two anti-skidding boss and Antiskid screw 4 preferably can be evenly distributed in clamping slot.In the present embodiment, groove 21 and groove 31 are arc groove.But in actual manufacture process, lower fixture block 2 is provided with groove 21, clamping slot is put together by groove 21 and upper fixture block 3; Or upper fixture block 3 is provided with groove 31, clamping slot is put together by groove 31 and lower fixture block 2.
On clamp assembly, be at least provided with two upper fixture blocks 3 of putting side by side along clamping slot; Or on clamp assembly, be at least provided with two lower fixture blocks 2 of putting side by side along clamping slot.Clamp assembly clamps isolating switch by lower fixture block 2 and upper fixture block 3, and this is the most simply to assemble scheme.But in actual manufacture process, along on the axial direction of groove 21 or groove 31, fixture block 3 on polylith can be set and be fixed on lower fixture block 2, while increasing rotary isolation switch, the frictional force between clamp assembly and isolating switch; Or along on the axial direction of groove 21 or groove 31, fixture block 2 under polylith can be set and be fixed on fixture block 3, while increasing rotary isolation switch, the frictional force between clamp assembly and isolating switch.
Upper fixture block 3 is fixed on lower fixture block 2 by threaded rod 5, and still, in actual manufacture process, upper fixture block 3 one end are connected on lower fixture block 2 by hinged, and the other end is locked upper fixture block 3 and lower fixture block 2 by threaded rod 5.
Antiskid screw 4 enters in groove 31 by manual rotation.But in actual manufacture process, also can control by operating grip 1 axial motion of Antiskid screw 4.At operating grip 1 overcoat driving gear, in the end of Antiskid screw 4, the driven gear engaging with driving gear is set simultaneously, then, rotating operating handle 1, makes Antiskid screw 4 exit from the position of withstanding isolating switch.Described operating grip 1 is insulating material, and the benefit of controlling Antiskid screw 4 by operating grip 1 is effectively to avoid operating personnel's manual rotation Antiskid screw 4 and accidental shock.
In the present invention, Antiskid screw 4 is arranged on fixture block 3.But in actual manufacture process, Antiskid screw 4 can be arranged on lower fixture block 2, also can on lower fixture block 2 and upper fixture block 3, be provided with Antiskid screw 4 simultaneously simultaneously.
On one end of the present invention's fixture block 2 under operating grip 1 connects, be provided with connecting rod 11, lower fixture block 2 is provided with the location hole 22 matching with connecting rod 11.But in actual manufacture process, can on upper fixture block 3, be provided with the location hole matching with connecting rod 11, or lower fixture block 2 and upper fixture block 3 are provided with the location hole matching with connecting rod 11 simultaneously.
In a word, more than be preferred structure of the present invention, those skilled in the art can, according to the practical structures of isolating switch, do adaptive structural change to jacket-type operating grip, but any amendment that does not depart from function and structure principle of the present invention all will be included in claims of the present invention.
