I.e. in 20 stress of roller assembly, it is ensured that roller assembly 20 is not in tilt, can only be vertically moving.It ensure that roller bearing
The support effect of device 20.As a kind of evolutionary approach, preferably, multiple support balls 42 are provided with each supporting plate, and it is floating
The spheroid that dynamic flange 32 stretches out the support ball 42 of the fixed support plate 41 of one end connection of floating bracket 31 is pressed on floating bracket
31, the spheroid that float flange 32 stretches out one end connection support ball 42 of fixed support 11 is pressed on fixed support 11.Pass through branch
Sliding friction between fixed support plate 41 and fixed support 11 and floating bracket 31 is converted into rolling friction by support ball 42, so that
The frictional force that reduction float flange 32 is subject to when floating.And support ball 42 to be connected by screw thread with fixed support plate 41, because
This, can adjust support ball 42 and floating bracket 31 or solid by adjusting the connection between support ball 42 and fixed support plate 41
The distance of fixed rack 11, so as to reduce the requirement of the assembly precision of fixed support plate 41, facilitates the installation of whole device.
In above-described embodiment, the structure of the drag chain floating support device using unilateral support is given, for the present embodiment
It is two using bilateral support, the i.e. number of support base 10 for another drag chain floating support device provided, it is corresponding floating
The device of dynamic flange 32 is also two.Wherein, for bilateral support, roller assembly 20, each support base 10 and corresponding
The structure of drag chain floating support device of the buffer unit 30 with providing unilateral support in above-described embodiment is identical, herein no longer one by one
Repeat, only difference is that the set location of the fixed support plate 41 of stopping means 40 is changed, wherein, due to unilateral
Only have one end to be defined in the drag chain floating support device of support, therefore, restriction in the axial direction, it is necessary to be placed on the end,
And for the drag chain floating support device of bilateral support, because two ends are supported, therefore, for the restriction of axis direction
Different ends can be placed on to be defined, you can, again can be as with the restriction as shown in Figure 1 for carrying out axis direction in same one end
Shown in Fig. 4 and Fig. 5, different restrictions are carried out at two ends, its principle all same, the only set location of fixed support plate 41
The change of generation.Preferably, the number of support base 10 is two, and each correspondence of float flange 32 one fixed support plate of connection
41.Bilateral restriction is used, so as to facilitate the installation of whole equipment.And on fixed support plate 41 it is same using support ball 42 come
Improve frictional force.Multiple support balls 42 are provided with i.e. each fixed support plate 41, and the spheroid of support ball 42 is pressed on fixation
Support 11 or floating bracket 31, so that whole device can timely be floated when by external force.
Obviously, those skilled in the art can carry out the essence of various changes and modification without departing from the present invention to the present invention
God and scope.So, if these modifications and variations of the present invention belong to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these changes and modification.
