Abstract
The utility model discloses a connecting piece is dismantled to main shaft rim plate, which comprises a body, its upper portion of body establish to cylindrical structure, be equipped with internal thread hole shape structure among them, its lower part of body establish equally to cylindrical structure, its the below be equipped with a circular shape through -hole, establish among them to hollow structure, body bottom establish to round platform shape structure, the utility model discloses the design of bottom round platform shape structure can be avoided in the use with lower part hollow structure's the great design of internal diameter, take place that the rim plate drops dangerous and the internal thread rotation condition such as excessive.
Description
Technical field
The utility model relates to a kind of engineering goods, specifically a kind of main shaft wheel disc dismounting connector.
Background technology
Some connectors on existing market, structure is comparatively simple and easy, and usually just one is provided with the cylinder of internal thread hole, if for the dismounting of this main shaft wheel disc, can occur easily wheel disc to be pulled through head, the danger of dropping; When also easily occurring connector to screw in main shaft, rotate excessive situation, be difficult to take off so that there is connector, cause the damage of main shaft.
Summary of the invention
The utility model provides a kind of main shaft wheel disc dismounting connector.
The purpose of this utility model solves more existing connectors, and structure is comparatively simple and easy, and usually just one is provided with the cylinder of internal thread hole, if for the dismounting of this main shaft wheel disc, can occur easily wheel disc to be pulled through head, the danger of dropping; When also easily occurring connector to screw in main shaft, rotate excessive situation, be difficult to take off so that there is connector, cause the problem that main shaft damages.
The utility model solves the technical scheme that its technical problem adopts: a kind of main shaft wheel disc dismounting connector, comprise body, its top of described body is set to cylindrical structure, internal thread hole shape structure is provided with in the middle of it, described body its underpart is set to cylindrical structure equally, be provided with a circular through hole below it, be set to hollow-core construction in the middle of it, described body bottom portion is set to truncated cone-shaped structure.
The external diameter of described truncated cone-shaped structure is greater than the external diameter of body.
The internal diameter of the internal thread hole of described body upper part is less than the internal diameter of body lower part central hollow structure.
Bottom the utility model, the design of truncated cone-shaped structure and the larger design of the internal diameter of lower hollow structure can be avoided in use, and the situations such as danger that wheel disc drops and internal thread rotation degree of turning over occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be the utility model entirety separately time structural representation.
Structural representation when Fig. 3 is the utility model overall co-ordination.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in the figure, the utility model comprises body 1, described its top of body 1 is set to cylindrical structure, internal thread hole shape structure 2 is provided with in the middle of it, described body 1 its underpart is set to cylindrical structure equally, be provided with a circular through hole 4 below it, be set to hollow-core construction 3 in the middle of it, described body bottom portion is set to truncated cone-shaped structure 5.
The external diameter of described truncated cone-shaped structure 5 is greater than the external diameter of body 1.
The internal diameter of the internal thread hole 2 of described body upper part is less than the internal diameter of body 1 bottom central hollow structure 3.
During use, the utility model is rotated into the outside threaded holes 6 of main shaft 7 front end, then the wheel disc 8 on main shaft 7 is pulled out.
