Abstract
The utility model relates to a connector which comprises two symmetrically equipped mounting fixing parts. The mounting fixing parts are symmetrically provided with two shaft holes. A shaft passes through the two shaft holes. An annular bearing sleeve is fixed between the two mounting fixing parts. A bearing is respectively provided between the inner walls at two ends of the bearing sleeve and the shaft. The opposite surface of the mounting fixing parts are provided with annular bosses coaxially with the shaft holes for abutting against the inner rings of the bearing. The outer diameter of each annular boss is smaller than the inner diameter of each outer ring of bearing. According to the technical solution, the utility model provides the connector which causes good rotation of the outer rings of bearing.
Description
Technical field
The utility model relates to a kind of link.
Background technique
A kind of link that is used on the entertainment for children equipment, include symmetrically arranged two mounting fixing parts, on mounting fixing parts, be arranged with axis hole, be provided with axle between two axis holes, be provided with the bearing housing of an annular between two mounting fixing parts, be equipped with bearing between the inwall at bearing housing two ends and the axle, when the interior ring of bearings at both ends, outer shroud contact with the opposing side of two mounting fixing parts, make frictional force bigger, hinder the rotation of outer race, cause unnecessary loss.
The model utility content
The purpose of this utility model: in order to overcome the defective of prior art, the utility model by on the opposing side of mounting fixing parts with the annular boss of the coaxial bearing inner ring that is provided for conflicting of axis hole, the external diameter of annular boss is less than the internal diameter of outer race, thereby a kind of link that can make that outer race rotates well is provided.
The technical solution of the utility model: a kind of link, include symmetrically arranged two mounting fixing parts, wear one being arranged with on the described mounting fixing parts between axis hole, described two axis holes, be provided with between described two mounting fixing parts annular sleeve, described bearing housing two ends inwall and the axle between be equipped with bearing, with the coaxial annular boss that is provided with the bearing inner ring that is used to conflict of described axis hole, the external diameter of described annular boss is less than the internal diameter of outer race on the opposing side of described mounting fixing parts.Adopt technique scheme, the interior ring of annular boss and bearing is inconsistent, can prevent that the outer shroud of bearing from contacting with the opposing side of mounting fixing parts, hinders the rotation of outer race.
Further improvement of the utility model: the external diameter of described annular boss equates that with the external diameter of described bearing inner ring the internal diameter of described annular boss equates with shaft hole diameter.Adopt above-mentioned further improvement, it is more stable to make annular boss and bearing inner ring conflict, better effects if.

Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is the utility model and dull and stereotyped structure sectional view of fixedlying connected;
Fig. 3 is the structure sectional view that the utility model is fixedlyed connected with cylinder.
Embodiment
As shown in Figure 1, a kind of link, include symmetrically arranged two mounting fixing parts 1, on described mounting fixing parts 1, be arranged with axis hole 2, wear one 3 between described two axis holes 2, be provided with an annular sleeve 4 between described two mounting fixing parts 1, be equipped with bearing 5 between the inwall at described bearing housing 4 two ends and the axle 3, bearing 5 is conventional bearing, ring 51 in comprising, outer shroud 52 and be arranged in the ring 51, ball 53 between the outer shroud 52, with the coaxial annular boss 6 that is provided with the bearing inner ring that is used to conflict of described axis hole 2, the external diameter of described annular boss 6 is less than the internal diameter of outer race 52 on the opposing side of described mounting fixing parts 1.Link can also can be installed to the needs that are fit to different occasions on the cylinder 8 by symmetrically arranged two mounting fixing parts 1 being installed on dull and stereotyped 7.As shown in Figure 2, be welded on dull and stereotyped 7 for mounting fixing parts 1 link.As shown in Figure 3, be welded on the cylinder 8 for mounting fixing parts 1 link.
In this specific embodiment, described annular boss 6 is through being stamped to form, and is easy to process like this, saves material.
In this specific embodiment, the external diameter of described annular boss 6 equates with the external diameter of described bearing inner ring 51, the internal diameter of described annular boss 6 and axis hole 2 equal diameters.Like this, easy to process and annular boss 6 is better with contacting of bearing inner ring 51.
Claims (2)
1. link, include symmetrically arranged two mounting fixing parts, wear one being arranged with on the described mounting fixing parts between axis hole, described two axis holes, be provided with between described two mounting fixing parts annular sleeve, described bearing housing two ends inwall and the axle between be equipped with bearing, it is characterized in that: with the coaxial annular boss that is provided with the bearing inner ring that is used to conflict of described axis hole, the external diameter of described annular boss is less than the internal diameter of outer race on the opposing side of described mounting fixing parts.
2. link according to claim 1 is characterized in that: the external diameter of described annular boss equates that with the external diameter of described bearing inner ring the internal diameter of described annular boss equates with shaft hole diameter.
