Abstract
The utility model discloses a connecting piece of a device. The connecting piece of the device comprises two installation fixed pieces symmetrically arranged. Axle holes are symmetrically arranged in the installation fixed pieces. An axle rod is arranged between the two axle holes. A circular shaft sleeve is arranged between the two installation fixed pieces. Bearings are arranged between the inner walls at both ends of the shaft sleeve and the axle rod. A circular bump leaning against a bearing inner race is arranged on the inner wall of the installation fixed piece. Both ends of the axle rod respectively extend out of the outer walls of the two installation fixed pieces. One end of the axle rod is an axle rod cap while the other end of the axle rod is provided with a thread and fastened by a nut. According to the connecting piece of the device provided by the utility model, the problem that a bearing outer race is prevented from rotating caused by opposite face contact of the outer race of the bearing and the installation fixed pieces with collision of the circular bump and the inner race of the bearing can be solved, so that the bearing outer race drives the shaft sleeve to rotate agilely. The axle rod is in threaded connection, can be detached, and is convenient to maintain, and parts are convenient to change.
Description
Technical field
The utility model relates to a kind of equipment connection spare.
Background technique
A kind of for the link on the entertainment for children equipment, include symmetrically arranged two mounting fixing parts, be arranged with axis hole at mounting fixing parts, be provided with axostylus axostyle between two axis holes, be provided with the axle sleeve of an annular between two mounting fixing parts, be equipped with bearing between the inwall at axle sleeve two ends and the axostylus axostyle, when the opposing side of the interior ring of bearings at both ends, outer shroud and two mounting fixing parts contacts, so that frictional force is larger, hinder the rotation of outer race, and this link is processed into integral body when producing, and can only integral body change when some parts are damaged.
The model utility content
For the problem that above-mentioned prior art exists, the utility model purpose be to provide a kind of rotations well, convenient maintenance and replacement equipment connection spare.
The technical solution of the utility model is: a kind of equipment connection spare, include symmetrically arranged two mounting fixing parts, be arranged with axis hole at mounting fixing parts, be provided with axostylus axostyle between two axis holes, be provided with the axle sleeve of an annular between two mounting fixing parts, be equipped with bearing between the inwall at axle sleeve two ends and the axostylus axostyle, the inwall of described mounting fixing parts is provided with the annular boss of conflict bearing inner race, the outer wall of two mounting fixing parts is stretched out respectively at the two ends of described axostylus axostyle, one end of axostylus axostyle is the axostylus axostyle cap, the other end is provided with screw thread, and passes through fastening nuts.
As preferably, the external diameter of described annular boss is identical with the external diameter of bearing inner race, and the internal diameter of annular boss is identical with the diameter of axis hole.
The beneficial effects of the utility model are: adopt the inner ring of annular boss and bearing inconsistent, the outer ring that can solve bearing contacts with the opposing side of mounting fixing parts, hinder the problem of bearing outer ring rotation, thereby make bearing outer ring drive the axle sleeve flexible rotating, axostylus axostyle adopts and is threaded, can dismantle the easy maintenance and replacement parts.
