Abstract
The utility model discloses a graphite shaft sleeve for the hand-operating mechanism of an isolation switch, which is formed by a shaft sleeve and characterized in that the wall of the shaft sleeve is provided with circular holes, and graphite blocks are embedded inside the circular holes. The graphite shaft sleeve for the hand-operating mechanism of an isolation switch is simple in structure, can be automatically lubricated, is corrosion-resistant and antioxidant, is flexible in rotation and time-saving and labor-saving in operation, enables the service life to be prolonged and the maintenance frequency to be reduced, and can be widely used for the hand-operating mechanism of an isolation switch.
Description
Technical field
The utility model relates to a kind of improvement of axle sleeve, specifically a kind of isolating switch manual-operating mechanism graphite bushing.
Background technology
Isolating switch can divide Multiple Type and specification according to its purposes difference, and consumption is very large in electrical network, and the rotating part of its manual-operating mechanism all has rotation axis and axle sleeve to consist of, and axle sleeve is enclosed within on the rotation axis, and axle sleeve is a tubular steel pipe.The shortcoming of this axle sleeve is: isolating switch in the situation that long-time not deciliter, axle sleeve and rotation axis are very easy to oxidation corrosion, cause the rotation axis rotation very difficult, even can not rotate, and waste time and energy during repairing.
Summary of the invention
The purpose of this utility model is to provide a kind of isolating switch manual-operating mechanism graphite bushing of avoiding axle sleeve and rotation axis oxidation corrosion, reducing maintenance frequency, be convenient to keep in repair.
For reaching above purpose, the technical scheme that the utility model adopts is: this isolating switch manual-operating mechanism graphite bushing, consisted of by axle sleeve, axle sleeve is a tubular steel pipe, it is characterized in that having circular hole at the wall of axle sleeve, graphite block is housed in circular hole, because graphite block has the performance of lubricated and not corrosion, so, make the axle sleeve that graphite block is housed can avoid oxidation corrosion.
The utility model is also implemented by following measure: the circular hole on the described axle sleeve wall is established upper and lower two rings, and every ring is established 4 symmetrically, all is embedded with graphite block in each circular hole, and graphite block is to insert to pressurize in the circular hole with graphite powder to form; Length and the diameter of the rotation axis of the length of axle sleeve and diameter and isolating switch manual-operating mechanism are complementary.When using the utility model, this axle sleeve is enclosed within on the rotation axis of isolating switch manual-operating mechanism, repeatedly rotation by rotation axis, can make on the rotation axis with one deck graphite powder, so, both played lubrication, and made again the inner surface of the surface of rotation axis and axle sleeve with one deck graphite powder, thereby played anti-corrosion, anti-oxidation.
The beneficial effects of the utility model are: compare with the axle sleeve that present isolating switch manual-operating mechanism uses, not only simple in structure, and can self-lubricate, anti-corrosion, anti-oxidation, rotate flexibly, operation is time saving and energy saving, can improve useful life, reduce maintenance frequency, can be widely used in the isolating switch manual-operating mechanism.
Description of drawings
Fig. 1 is that the utility model structure master looks schematic diagram;
Fig. 2 is that the utility model is along Figure 1A-A cross-sectional schematic;
Fig. 3 is that the utility model is along Figure 1B-B cross-sectional schematic;
Among the figure: 1, axle sleeve; 2, graphite block.
Embodiment
Make the utility model with reference to accompanying drawing 1, Fig. 2, Fig. 3.This isolating switch manual-operating mechanism graphite bushing is made of axle sleeve 1, and axle sleeve 1 is a tubular steel pipe, it is characterized in that: the wall at axle sleeve 1 has circular hole, is embedded with graphite block 2 at circular hole.
Described circular hole is established upper and lower two rings, and every ring is established 4 symmetrically, all is embedded with graphite block 2 in each circular hole; Length and the diameter of the rotation axis of the length of axle sleeve 1 and diameter and isolating switch manual-operating mechanism are complementary.
Claims (2)
1. isolating switch manual-operating mechanism graphite bushing is made of axle sleeve (1), and it is characterized in that: the wall at axle sleeve (1) has circular hole, is embedded with graphite block (2) at circular hole.
2. isolating switch manual-operating mechanism graphite bushing according to claim 1, it is characterized in that: the circular hole on described axle sleeve (1) wall is established upper and lower two rings, and every ring is established 4 symmetrically, all is embedded with graphite block (2) in each circular hole.
