Abstract
The utility model relates to a kind of wire drawing connecting lever used for high-voltage switch.The connecting lever cover (2) comprising connecting lever sheet (4) and be connected with connecting lever sheet (4), the sheathed rotating shaft of described connecting lever cover (2) endoporus (3), the contact site of connecting lever cover (2) and rotating shaft (3) establishes coarse structure in correspondence with each other, and connecting lever cover (2) is provided with the retention mechanism reduced by connecting lever cover (2) endoporus.Change between connecting lever of the present utility model cover endoporus and rotating shaft and traditional be smoothly connected form, frictional force is strengthened in two parts junctions, both adhesions are made greatly to strengthen like this, the utility model arranges the form of fastening bolt simultaneously, the snap-in force that connecting lever is overlapped between rotating shaft strengthens greatly, thus further ensure that and can produce enough large frictional force between the two.
Description
Technical field
The utility model relates to a kind of wire drawing connecting lever used for high-voltage switch, belongs to High-Voltage Electrical Appliances isolating switch technology.
Background technology
Being applied to the high voltage isolator operation connecting lever of electric power system at present, is the supporting of optical axis and unthreaded hole with the supporting position of isolating switch rotating shaft.Such benefit is easy to process, but very inconvenient when Installation and Debugging, needs, in the boring of Installation and Debugging scene professional equipment, to beat spring pivot.And once boring, as angle slightly deviation, then have a strong impact on debugging.
Utility model content
The utility model is for above-mentioned defect, and object is the one wire drawing connecting lever used for high-voltage switch providing a kind of structure simple, easy to adjust.
The technical solution adopted in the utility model is for this reason: the connecting lever cover (2) that the utility model comprises connecting lever sheet (4) and is connected with connecting lever sheet (4), the sheathed rotating shaft of described connecting lever cover (2) endoporus (3), the contact site of connecting lever cover (2) and rotating shaft (3) establishes coarse structure in correspondence with each other, and connecting lever cover (2) is provided with the retention mechanism reduced by connecting lever cover (2) endoporus.
Described coarse structure is for being arranged on the groove in correspondence with each other on connecting lever cover (2) endoporus, rotating shaft (3) cylindrical.
Described connecting lever cover (2) has a bifurcation structure, and described retention mechanism comprises a fastening bolt (1), and connecting lever cover (2) endoporus is reduced or expands by the distance between adjustment two bifurcated by described fastening bolt (1).
Integral type or split-type structural is formed between described connecting lever cover (2) and connecting lever sheet (4).
Described connecting lever applies in GN19, GN22, GN24, GN27, GN30 high_voltage isolation and earthed switch.
The utility model has the advantages that: 1) change between connecting lever of the present utility model cover endoporus and rotating shaft and traditional be smoothly connected form, frictional force is strengthened in two parts junctions, both adhesions are made greatly to strengthen like this, the utility model arranges the form of fastening bolt simultaneously, the snap-in force that connecting lever is overlapped between rotating shaft strengthens greatly, thus further ensure that and can produce enough large frictional force between the two; 2) the utility model adopts the version of fastening bolt, and its version is simple, easy to adjust; 3) the utility model adopts insection structure form, makes the contact site uniform force between connecting lever cover with rotating shaft, thus because of the larger generation damage of power, can not improve its useful life between the two.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 be fastening bolt, 2 be connecting lever cover in figure, 3 be rotating shaft, 4 for connecting lever sheet.
Embodiment
The connecting lever cover 2 that the utility model comprises connecting lever sheet 4 and is connected with connecting lever sheet 4, described connecting lever overlaps the sheathed rotating shaft 3 of 2 endoporus, and connecting lever cover 2 and the contact site of rotating shaft 3 establish coarse structure in correspondence with each other, and connecting lever cover 2 is provided with retention mechanism connecting lever being overlapped 2 endoporus and reduce.
Described coarse structure is be arranged on connecting lever to overlap groove in correspondence with each other on 2 endoporus, rotating shaft 3 cylindrical.
Described connecting lever cover 2 has a bifurcation structure, and described retention mechanism comprises a fastening bolt 1, and connecting lever is overlapped 2 endoporus by the distance between adjustment two bifurcated and reduces or expand by described fastening bolt 1.
Integral type or split-type structural is formed between described connecting lever cover 2 and connecting lever sheet 4.
The course of work of the present utility model is: during debugging, connecting lever cover 2 is enclosed within high-voltage switch gear rotating shaft 3 termination cylindrical, tights a bolt 1, then high-voltage switch gear rotating shaft 3 termination cylindrical tightly bitten by connecting lever cover 2, does not need to beat spring pivot in boring.As angle has error, only need bolt 1 of becoming less severe, rotate suitable angle just.
Described connecting lever applies in all kinds of high_voltage isolation such as GN19, GN22, GN24, GN27, GN30 and earthed switch.
Claims (4)
1. a wire drawing connecting lever used for high-voltage switch, it is characterized in that, the connecting lever cover (2) comprising connecting lever sheet (4) and be connected with connecting lever sheet (4), the sheathed rotating shaft of described connecting lever cover (2) endoporus (3), the contact site of connecting lever cover (2) and rotating shaft (3) establishes coarse structure in correspondence with each other, and connecting lever cover (2) is provided with the retention mechanism reduced by connecting lever cover (2) endoporus.
2. one according to claim 1 wire drawing connecting lever used for high-voltage switch, is characterized in that, described coarse structure is for being arranged on the groove in correspondence with each other on connecting lever cover (2) endoporus, rotating shaft (3) cylindrical.
