Description
Technical field
The utility model relates to a kind of high voltage isolating switch operating mechanisms.
Background technique
Currently, connecting lever covers on switch shaft, and join operation bar is tightened after the disconnecting switch installation of the prior art is fixed
Connecting lever positioning bolt, then rotary operation mechanism make to switch opening and closing in place, and the sleeve of connecting lever is directly sleeved in shaft at this time, angle R
It after adjusting, then drills together in shaft from operation connecting lever sleeve, adds and beat expansion pin, because of connecting lever and the shaft torsion to be born
Greatly, it is necessary to useAperture expansion pin, processing drilling cannot remove workpiece again on 30mm circular shaft diameter, cause difficulty of processing very big.
When can change because of switch mounting height H, so that angle R between operating stick and connecting lever is followed variation, cause to position
Positioning process can only be carried out by actual installation situation by expanding pin hole, can not unify positioning expansion pin hole site.
Huge torsion fully relies on expansion pin transmitting and drives switch shaft rotation when switch operation.Its expansion pin quality is straight
Connect the normal division of relationship switch.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of high voltage isolator
Operating mechanism, it does not need to process expansion pin fixation hole on connecting lever and shaft, can substantially shorten the set-up time, it is full to improve work efficiency
The opening and closing in place requirement switched enough, and it is able to bear biggish torsion when switch operation.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of high voltage isolating switch operating mechanism,
It is used for disconnecting switch operation, and the disconnecting switch has switch shaft, it includes:
Loop bar, the loop bar are fixedly connected on the end of switch shaft, have external tooth form structure on the outer wall of the loop bar；
Connecting lever, the one end of the connecting lever are provided with sleeve, are equipped on the inner wall of the sleeve and external tooth form structure phase
It is engaged the internal tooth form structure of cooperation, when sleeve is placed on the loop bar, the internal tooth form structure and the external tooth form structure phase
Occlusion；
Operating stick, the one end of the operating stick and the other end of the connecting lever are hinged；
Operation panel, the operation panel are flexibly connected with the other end of the operating stick.
Further, reference circle of the reference diameter of the external tooth form structure of the loop bar than the internal tooth form structure of the sleeve
The small 0.2mm of diameter.
After above-mentioned technical proposal, the utility model have it is below the utility model has the advantages that
1, it only needs for the sleeve on connecting lever to be directly sleeved on the loop bar to match after improving, by adjusting external tooth form structure
With the engaged position of internal tooth form structure, so that it may which the opening and closing in place requirement for meeting switch does not need to process on connecting lever and shaft swollen
Expansion pin fixation hole can substantially shorten set-up time raising work efficiency；
2, the number of teeth for the ratcheting structure that external tooth form structure and internal tooth form structure are formed is answered more, conducive to the more smart of angle adjustment
Close, which not only ensure that operating stick to the operation torsion of shaft, also have because of angle corresponding to mounting height difference
Spend the versatility demand of adjustment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the high voltage isolating switch operating mechanism of the utility model；
Fig. 2 is the sleeve of the utility model and the structural schematic diagram of loop bar engagement.
Specific embodiment
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model.
As shown in Figure 1, 2, a kind of high voltage isolating switch operating mechanism, it is used for disconnecting switch operation 10, described to keep apart
Closing 10 has switch shaft, it includes:
Loop bar 1, the loop bar 1 are fixedly connected on the end of switch shaft, have external tooth form knot on the outer wall of the loop bar 1
Structure；
Connecting lever 2, the one end of the connecting lever 2 are provided with sleeve 21, are equipped on the inner wall of the sleeve 21 and external tooth form
Structure is mutually engaged the internal tooth form structure of cooperation, when sleeve 21 is placed on the loop bar 1, the internal tooth form structure and the external tooth
Shape structure is mutually engaged；
Operating stick 3, the one end of the operating stick 3 and the other end of the connecting lever 2 are hinged；
Operation panel 4, the operation panel 4 are flexibly connected with the other end of the operating stick 3.
Reference diameter of the reference diameter of the external tooth form structure of the loop bar 1 than the internal tooth form structure of the sleeve 21
Small 0.2mm.
After improvement, it is only necessary to the sleeve 21 on connecting lever 2 is directly sleeved on the loop bar 1 to match, by adjusting external tooth form
The engaged position of structure and internal tooth form structure, so that it may which the opening and closing in place requirement for meeting switch does not need to add on connecting lever 2 and shaft
Work expansion pin fixation hole can substantially shorten set-up time raising work efficiency；
In addition, the number of teeth for the ratcheting structure that external tooth form structure and internal tooth form structure are formed answer it is more, conducive to angle adjustment
More accurate, which not only ensure that operating stick to the operation torsion of shaft, also have because corresponding to mounting height difference
Angle adjustment versatility demand.
Particular embodiments described above, to the utility model solve the technical issues of, technical scheme and beneficial effects into
It has gone further description, it should be understood that the foregoing is merely specific embodiment of the utility model, and has not had to
In limitation the utility model, within the spirit and principle of the utility model, any modification, equivalent substitution and improvement done
Deng should be included within the scope of protection of this utility model.
