Description
Technical field
The utility model relates to castor technical field, refers to a kind of castor link span especially.
Background technology
The upper rolling disc being rotationally connected head of existing castor link span and the riveted joint of lower rolling disc have following two kinds of situations: with reference to Fig. 4 to Fig. 5, one, rolling disc and connecting panel pass through rivet, rivet spare and accessory parts will be increased like this, will increase assembly error (accumulated error), and often increase spare and accessory parts also can increase cost.Two, rolling disc and connecting panel are riveted by drawing pack arrangement, the insufficient strength connected like this, because easily explosion after riveted joint, described very high to material quality requirement, cost is also very high.Thus the in-use performance reduced on the whole after riveted joint.
Therefore, must make improvements for above-mentioned defect.
Utility model content
The utility model proposes a kind of castor link span, solve the problem of the in-use performance difference in prior art after the riveted joint of rolling disc and connecting panel.
The technical solution of the utility model is achieved in that
A kind of castor link span, comprise mounting bracket, described mounting bracket is provided with connecting panel, rolling disc is provided with above described connecting panel, described rolling disc lower surface is provided with the first arc groove, described connecting panel upper surface is provided with the second arc groove matched with described first arc groove, described connecting panel lower surface is provided with three-arc groove, described rolling disc and described connecting panel are riveted by pipe rivet, described pipe rivet comprises pipe and spacing ring, described spacing ring is provided with the 4th arc groove matched with described three-arc groove, described pipe one end is connected with described rolling disc, the described pipe other end is connected with described spacing ring one end, described rolling disc, described pipe and described spacing ring one-body molded, the first rolling member is provided with between described first arc groove and described second arc groove, the second rolling member is provided with between described three-arc groove and described 4th arc groove.
Further, described first rolling member is ball.
Further, described second rolling member is ball.
Further, described rolling disc is provided with the first mounting hole
Further, described mounting bracket is provided with the second mounting hole.
Enforcement the beneficial effects of the utility model have:
The utility model by being provided with integrated pipe and spacing ring on rolling disc, spacing ring is that pipe upset is formed, namely such riveting method can reduce the buying of spare and accessory parts and installation steps and cost, accumulated error can be avoided again, improve the precision of connection, improve the in-use performance of castor link span.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to figs. 1 through Fig. 3, a kind of castor link span that the utility model provides, comprise mounting bracket 3, mounting bracket 3 is provided with connecting panel 8, connecting panel 8 is provided with rolling disc 1 above, rolling disc 1 lower surface is provided with the first arc groove 5, connecting panel 8 upper surface is provided with the second arc groove 9 matched with the first arc groove 5, connecting panel 8 lower surface is provided with three-arc groove 7, rolling disc 1 and connecting panel 8 are riveted by pipe rivet 12, pipe rivet 12 comprises pipe and spacing ring, spacing ring is provided with the 4th arc groove 11 matched with three-arc groove 7, pipe one end is connected with rolling disc, the pipe other end is connected with spacing ring one end, rolling disc 1, pipe and spacing ring one-body molded, the first rolling member 6 is provided with between first arc groove 5 and the second arc groove 9, the second rolling member 10 is provided with between three-arc groove 7 and the 4th arc groove 11.Spacing ring was a part for pipe lower end before rolling disc 1 and connecting panel 8 are not riveted, by just forming the spacing ring with the 4th arc groove 11 after the riveted joint of pipe flange, namely such 4th arc groove 11 can play the effect of placing ball, the effect that riveted joint is spacing can be played again, thus avoid parts too much, also can reduce costs and too much cause product in-use performance bad with part.
