Specific embodiment
To describe composition of the present utility model and operation principle below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Embodiment one
Referring to accompanying drawing 1 and accompanying drawing 2, a kind of spherical free bearing for door body folding of the present utility model, by fixed hinged seat 1,
Movable free bearing 2, steel ball 3, compression spring 4, ring flange 5, screw 6, plug bolt forms.
Wherein, fixed hinged seat 1, movable free bearing 2 forms Contiuum type structure.Affixed on the connecting bottom board 13 of fixed hinged seat 1
There is hinged set, this hinged set includes being fixed in the lower hinged set 11 of connecting bottom board 13 bottom and is fixed in connecting bottom board 13 top
Upper hinged set 12, upper and lower hinged set 12,11 has same diameter and the perforation 11.1 of same axis.
The connecting bottom board 22 of movable free bearing 2 is connected with middle hinged set 21, this middle hinged set 21 is located at down hinged
Between set 11 and upper hinged set 12, in the upper and lower end of middle hinged set 21, coaxial line be provided with hemispheric notch 21.1.
2 identical steel balls 3 are respectively placed in the upper and lower hemispheric notch 21.1 of middle hinged set 21.
In the bottom of lower hinged set 11, threadedly connect a plug bolt 7, the screw rod end of plug bolt 7
Portion is connected on the steel ball of lower half spherical notch 21.1, in the upper end of upper hinged set 12, connects a method by screw 6
Blue disk 5, is provided with compression spring 4 between ring flange 5 and the steel ball 3 being located at upper half spherical notch 21.1, after compression spring 4 is installed
A larger initial pressure must be kept.
In addition, after this spherical linkage is installed, between must leaving between upper and lower hinged set 12,11 and middle hinged set 21
