Description
Technical field
The present invention relates to a kind of damping unit, for unsettled runner.
Background technology
At present, unsettledly take turns existing syndeton and have potential safety hazard, runner is connected firm not with body frame, and unsettled wheel do not having under damping action, and velocity of rotation is too fast, and people is suspended on above and can causes health out of control, thereby throws injury health or sprain health.
Summary of the invention
The object of the invention is in order to overcome above deficiency, a kind of simple in structure, unsettled runner damping unit that security performance is high is provided.
Object of the present invention is achieved through the following technical solutions: a kind of unsettled runner damping unit, comprise main shaft weldment, the lower end of main shaft weldment is provided with swiveling wheel weldment, between swiveling wheel weldment and main shaft weldment, be provided with two clutch shaft bearings setting up and down, between two clutch shaft bearings, be provided with damper, the top that is placed in the clutch shaft bearing of top is provided with big spacing ring, on main shaft weldment, also cover has conduction weldment, conduction weldment top is provided with axis, axis is also enclosed within on main shaft weldment, and axis is provided with for locking the anti-theft locking bolt of conduction weldment.
Further improvement of the present invention is: the top that is placed in the first axle of top is provided with the first water proof ring, and the first water proof ring is placed in the outside of big spacing ring, and the below that is placed in the clutch shaft bearing of below is also provided with the first water proof ring.
Further improvement of the present invention is: two tops of axis are provided with bolt and antitheft cap.
Further improvement of the present invention is: the second bearing is all equipped with at the two ends of axis, and the outer end of each the second bearing is equipped with long spacer ring and water proof ring.
Further improvement of the present invention is: conduction weldment is provided with for controlling the kidney-shaped guide groove of anti-theft locking bolt.
The present invention compared with prior art has the following advantages:
1, unsettled runner has damping when rotated, avoids human body excessive velocities and sprain health when hang rotating;
2, on conduction weldment, there is kidney-shaped guide groove, can control the stroke of anti-theft locking bolt, thereby damper can be adjusted as required;
3, increase an axis and run through connection, improve security performance, prevent that anti-theft locking bolt from, long-time rear loosening the coming off of swiveling wheel weldment of causing, producing personal injury accident;
4, bearing is equipped with at axis two ends, and has water-tight device, makes to rotate wheel rim flexible swinging, noise is little.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-main shaft weldment, 2-swiveling wheel weldment, 3-clutch shaft bearing, 4-damper, 5-big spacing ring, 6-conduction weldment, 7-axis, 8-anti-theft locking bolt, 9-the first water proof ring, 10-bolt, the antitheft cap of 11-, 12-the second bearing, the long spacer ring of 13-, 14-water proof ring, 15-body frame attachment lug, 16-kidney-shaped guide groove.
the specific embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows a kind of embodiment of the unsettled runner damping unit of the present invention, comprise main shaft weldment 1, the lower end of main shaft weldment 1 is provided with swiveling wheel weldment 2, between swiveling wheel weldment 2 and main shaft weldment 1, be provided with two clutch shaft bearings 3 setting up and down, between two clutch shaft bearings 3, be provided with damper 4, the top that is placed in the clutch shaft bearing 3 of top is provided with big spacing ring 5, on main shaft weldment 1, also cover has conduction weldment 6, conduction weldment 6 tops are provided with axis 7, axis 7 is also enclosed within on main shaft weldment 1, and axis 7 is provided with for locking the anti-theft locking bolt 8 of conduction weldment 6.The top that is placed in the clutch shaft bearing 3 of top is provided with the outside that the first water proof ring 9, the first water proof rings 9 are placed in big spacing ring 5, and the below that is placed in the clutch shaft bearing 3 of below is also provided with the first water proof ring 9.Two tops of axis 7 are provided with bolt 10 and antitheft cap 11.The second bearing 12 is all equipped with at the two ends of axis 7, and the outer end of each the second bearing 12 is equipped with long spacer ring 13 and water proof ring 14.
Main shaft weldment 1 is first connected with swiveling wheel weldment 2, then main shaft weldment 1 is packed in conduction weldment 6, with 8 lockings of anti-theft locking bolt, on conduction weldment 6, has kidney-shaped guide groove 16, has enough strokes to produce damping; Finally above-mentioned parts are connected on body frame attachment lug 15.The present invention utilizes the working of plastics expansion principle that is squeezed, and with anti-theft locking bolt 8 locking conduction weldments, the damper by big spacing ring and bearing inner race extruding polyurethane material, makes damper distortion, increase and bearing between frictional force, reach damping.
Unsettled runner has damping when rotated, avoids human body excessive velocities and sprain health when hang rotating; On conduction weldment, there is kidney-shaped guide groove, can control the stroke of anti-theft locking bolt, thereby damper can be adjusted as required; Increase an axis and run through connection, improve security performance, prevent that anti-theft locking bolt from, long-time rear loosening the coming off of swiveling wheel weldment of causing, producing personal injury accident; Bearing is equipped with at axis two ends, and has water-tight device, makes to rotate wheel rim flexible swinging, noise is little.
