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. 6, one, upper rolling disc and lower rolling disc pass through rivet, rivet spare and accessory parts will be increased like this, will increase an assembly error (many accumulated errors), and increase spare and accessory parts also can increase cost.Two, upper rolling disc and lower rolling disc are by being connected to the hole flanging structure riveted joint on upper rolling disc, 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 rolling disc and the riveted joint of lower rolling disc.
Therefore, must make improvements for above-mentioned defect.
Utility model content
The utility model proposes a kind of castor link span, solve in prior art the problem of the in-use performance difference after going up rolling disc and the riveted joint of lower rolling disc.
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, described connecting panel is provided with rotation hole, described rotation hole is provided with and is rotationally connected head, the described head that is rotationally connected comprises rolling disc, upper rolling member, lower rolling member and lower rolling disc, described upper rolling disc is flexibly connected with described connecting panel upper surface by upper rolling member, described lower rolling disc is flexibly connected with described connecting panel lower surface by lower rolling member, described upper rolling disc runs through the convex closure of described rotation hole by one and described lower rolling disc is riveted, described convex closure and described upper rolling disc one-body molded.
Further, described upper rolling member is ball.
Further, described lower rolling member is ball.
Further, described upper rolling disc is provided with the upper rolling groove for installing rolling member.
Further, described lower rolling disc is provided with the lower rolling groove for installing lower rolling member.
Further, described mounting bracket is provided with castor mounting hole.
Enforcement the beneficial effects of the utility model have:
The mode that upper rolling disc convex closure of the present utility model and lower rolling disc are riveted realizes being rotationally connected the rotation of head, namely can reduce buying and the installation steps of spare and accessory parts, can reduce costs again, and can ensure the in-use performance being rotationally connected head.
Accompanying drawing explanation

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 2, mounting bracket 2 is provided with connecting panel 9, connecting panel 9 is provided with rotation hole, rotation hole is provided with and is rotationally connected 1, be rotationally connected 1 and comprise rolling disc 5, upper rolling member 4, lower rolling member 6 and lower rolling disc 7, upper rolling disc 5 is flexibly connected with connecting panel 9 upper surface by upper rolling member 4, lower rolling disc 7 is flexibly connected with connecting panel 9 lower surface by lower rolling member 6, upper rolling disc 5 is riveted with lower rolling disc 7 by the convex closure 8 that runs through rotation hole, convex closure 8 is one-body molded with upper rolling disc 5.Convex closure 8 is the cylinder protruded downwards when unassembled, cylinder inside is provided with the intercommunicating pore be communicated with cylinder upper surface, after riveted joint assembling, the cross section of convex closure is rendered as the font of falling T, and rolling disc 5 and lower rolling disc 7 so just can well be made to be riveted on rotation hole.Such riveting method structure is simple, easy for installation, and can also reduce costs and improve the service life of castor link span.
Upper rolling member 4 is ball.Lower rolling member 6 is ball.Certainly can according to the actual needs, upper rolling member 4 and lower rolling member 6 also can adopt roller to replace ball to use.
