Science and technology progress miniature parts cost reduction, corresponding brake component can be arranged in roller can design one kind can be i.e.
Stop fixed spherical roller.
Utility model content
In order to solve above-mentioned problem, the utility model, which provides one kind, can stop fixed spherical roller, the roller
Using spherical designs, it is mainly made up of three parts, and centre is contractile tourelle, and both sides are fixing device, outside
It is then movable wheel face, can realizes and stop as desired by internal contractile tourelle change, for up to this purpose, this reality
It can stop fixed spherical roller, including rotating shaft, side wheel face, movable wheel face, movable block, folding and roller with new offer one kind
Support bar, it is curved surface that the rotating shaft two ends, which are respectively fixed with the outside of a side wheel face, the side wheel face, and the side wheel face lower section is flat
Face, two side wheel faces are symmetrical arranged, and the movable wheel face is flexible face, and the movable wheel face constitutes ring surface after closing, each
There is a movable block on the inside of movable wheel face, there is folding the junction of two adjacent movable blocks, and the roller supporting bar includes stretching
Contracting bar and fix bar, the roller supporting bar angularly rotate shaft centre line one week, and the fix bar has one, the expansion link
Including expansion link fixed part and expansion link telescopic section, the expansion link telescopic section is inserted into corresponding expansion link fixed part
In the groove divided, each folding corresponds to a roller supporting bar, the folding and corresponding expansion link telescopic section or fixed boom end
It is connected, the tail end of the expansion link fixed part and fix bar is connected with rotating shaft outer wall.
Further improvement of the utility model, the expansion link has 3-7, and the utility model can be corresponding according to actual selection
Expansion link.
Further improvement of the utility model, the movable wheel face has friction lines, has can increasing for lines of friction to rub
Wipe power.
The utility model one kind can stop fixed spherical roller, and the design is spherical, when being rolled, center section
Five interior expansion links are in elongation state, and to maintain the shape of whole circular contour, roller can be rolled；It is quiet when needing
When only, control expansion link to be in the state of pinch in by external connection, to drive the deformation of whole six cambered surfaces, make centre
Spherical contraction is entered, so as to allow the plane contact ground of left and right two parts bottom, reaches the effect of static fixation, whole control pole
To be simple, it is only necessary to which expansion link is controlled, so without brake structure is external, corresponding structure can be simplified,
And good braking effect simple to operate.
