Abstract
The utility model relates to a lever toggle mechanism for interlocking device of automatic air switch, which comprises a cup-shaped subbase, a rotating shaft flexibly connected to the subbase, an eccentric piece fixed on the rotating shaft, a guiding axle fixed on the eccentric piece, and a toggling block which toggles the air switch. Two guiding rails are arranged vertically on the subbase, the toggling block constitutes slide connection with the guiding rails, a guiding groove on which the guiding axle is arranged and a rectangular hole on which the air switch lever is arranged are laterally arranged on the toggling block. The utility model has the advantages of easy operation and correct indication.
Description
The utility model relates to a kind of interlock of automatic air-break switch, particularly relates to a kind of interlock that air switch is cut off the electricity supply when opening the low-voltage distribution cabinet door.
The applicant has applied for that to Patent Office of the People's Republic of China name is called the utility model patent of " the handle toggle mechanism of automatic air-break switch interlock " on June 16th, 1992, the technical scheme of this application is: an end of shifting block is equipped with two rollers, the handle of air switch is inserted between described two rollers, the other end of shifting block is movably connected on the base, has gathering sill on the shifting block; Eccentric part is connected with the rotating shaft that drives its rotation, and eccentric part is provided with the axis of guide, and this axis of guide is inserted in the described gathering sill.Rotating shaft drives eccentric part and rotates, and the axis of guide of eccentric part slides in gathering sill, thereby drives shifting block around rotating with the active connection place of base, and the air switch handle between two rollers of drive shifting block disconnects or be closed.Following point takes place in such scheme in implementation process: when automatic air-break switch is in closure state, reason owing to installation dimension, the angle of shifting block and eccentric part axis just in time is 90 ° of formation " dead point ", this moment, the operator stirred operating grip with hand, can change operating state, but motionless rotating shaft just is with in tripping operation if automatic air-break switch meets with an accidet, and operating grip is still indicated at closure state, causes operating grip indicating status and automatic air-break switch actual working state inconsistent.
The purpose of this utility model provides a kind of handle toggle mechanism of stirring the automatic air-break switch interlock free and relaxed, that indicating correct is errorless.
Above-mentioned purpose can be achieved through the following technical solutions: a kind of handle toggle mechanism of automatic air-break switch interlock, it comprises: be spill base, be movably connected in rotating shaft on the base, with fixing eccentric part, the axis of guide on the eccentric part of rotating shaft, stir the shifting block of automatic air-break switch; Described base vertically be provided with two guide rails, described shifting block and guide rail are slidingly connected, and laterally are provided with the gathering sill of placing the axis of guide and the rectangular opening of placing the automatic switch handle on the shifting block; The operator slides up and down by the axis of guide drive shifting block that is inserted on the eccentric part in the gathering sill, and the automatic air-break switch handle that shifting block drives in its rectangular opening changes operating state; During tripping operation, the automatic air-break switch handle drives shifting block, and shifting block drives eccentric part by the axis of guide in the gathering sill, rotating shaft, and rotating shaft makes operating grip rotate indication at " tripping operation " state.
The utlity model has following advantage:
1. operating grip drives shifting block by rotating shaft, eccentric part, the axis of guide and stirs the automatic air-break switch handle, and action is accurate, and switch working state is consistent with the handle indicating positions.
2. simple in structure, rapid operation is convenient.
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing 1 is a front view of the present utility model;
Accompanying drawing 2 is vertical views of Fig. 1.
Wherein: 1. base; 2. rotating shaft; 3. eccentric part; 4. the axis of guide; 5. shifting block; 6. guide rail; 7. gathering sill; 8. rectangular opening; 9. pad; 10. rotating shaft cover; 11. screw; 12. crimping; 13. roller; 14. retainer plate.
By Fig. 1,2 as can be known, a kind of toggle mechanism of automatic air-break switch interlock, it comprises: the base 1, rotating shaft 2, eccentric part 3, the axis of guide 4, shifting block 5 and the guide rail 6 that are spill; Described rotating shaft 2 is fixed on the rotating shaft cover 10 by secure fit, and insert in the hole of base, eccentric part 3 and pad 9 are fixed on the rotating shaft cover 10 by screw 11, make eccentric part 3 to rotate with respect to base 1 with rotating shaft 2, eccentric part 3 is provided with the axis of guide 4, the axis of guide 4 is equipped with roller 13, and the axis of guide 4 and roller 3 are inserted in the gathering sill 7; Described guide rail 6 is vertically fixed on the base 1 by retainer plate 14; There is the crimping 12 that can surround guide rail 6 described shifting block 5 both sides, and shifting block 5 can be slided up and down on guide rail 6, have rectangular opening 8 in the middle of the shifting block 5, and the air switch handle is inserted in this rectangular opening 8.During work, operator's control crank rotates rotating shaft 2, and rotating shaft 2 drives eccentric part 3 and slides up and down by the axis of guide 4 drive shifting blocks 5, and shifting block 5 drives the air handles by rectangular opening 8 and changes operating state.During tripping operation, the air switch handle drives shifting block 5, and shifting block 5 rotates eccentric part 3 and rotating shaft 2 by the axis of guide 4, and rotating shaft 2 passes to the operating grip indication at " tripping operation " state with action.
Claims (3)
