Description

Technical Field

[0001] The utility model relates to the field of bushings, in particular to a bushing which is easy to fix. Background Art

[0002] For the rotating shaft of the single-end free-running bearing, one end of the shaft contacts the bushing, which is fixed by the bearing seat. Due to the deadweight of the rotating shaft, the bushing not only rubs against the rotating shaft, but also bears the pressure from the vertical surface. This causes the bearing seat to tilt after long-term use, affecting the posture of the rotating shaft and causing the rotating shaft to slide downward.

[0003] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a bushing that is easy to fix. The utility model is achieved through the following technical solutions:

[0005] A bushing that is easy to fix includes an outer shell and a bushing body, the outer shell and the bushing body are fixedly connected, the outer shell includes a base and a connecting tube, a plurality of connecting holes are evenly arranged on the base, and the central axis of the bushing body coincides with the central axis of the connecting tube.

[0006] In the above technical solution: the outer shell is used to fix the bushing body, and is also used to fix it on a supporting position such as a wall, so that the bushing body can remain horizontal; the bushing body is used to realize lubrication and support functions; the base is used to realize fixation with the supporting position; the connecting tube is used to set the bushing body; the connecting hole is used to set the bolt to achieve fixation; the central axis of the bushing body and the central axis of the connecting tube coincide, so that the force of the bushing can be transmitted to the connecting tube more evenly.

[0007] The utility model is further configured as follows: a plurality of graphite holes are arranged on the bushing body, and graphite columns are fixedly arranged in the graphite holes.

[0008] In the above technical solution: the graphite hole is used to set the graphite column; the graphite column is used to achieve the lubrication function when the rotating shaft rotates.

[0009] The utility model is further configured as follows: the base is fixedly arranged on the end surface of the connecting tube.

[0010] In the above technical solution: the base is fixedly arranged on the end surface of the connecting tube so that the rotating shaft will not contact the supporting position after contacting the bushing body, thereby causing interference.

[0011] The utility model is further configured as follows: a lubricating surface is provided on a surface of the bushing body on a side away from the base.

[0012] In the above technical solution: the lubricating surface is used to achieve lubrication of the stepped surface of the rotating shaft, thereby avoiding an increase in friction caused by contact between the side surface of the bushing body and the stepped surface of the rotating shaft.

[0013] The utility model is further configured as follows: a guide cone surface is further provided on a side surface of the bushing body away from the base.

[0014] In the above technical solution: the guiding cone surface is used to assist in the installation of the rotating shaft.

[0015] The utility model discloses a bushing which is easy to fix. Compared with the prior art:

[0016] 1. The utility model provides a housing and a base on the housing, so that after the bearing seat is assembled, the bushing body is subjected to both the lateral force of the bearing seat and the axial tension, so as to ensure that the bushing body will not deviate or tilt;

[0017] 2. The utility model also provides a lubricating surface so that there will be no large friction when the stepped surface of the rotating shaft contacts the bushing body, making the rotation smoother. BRIEF DESCRIPTION OF THE DRAWINGS
