Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The supporting mechanism for flexible minor diameter running shaft shown in Fig. 1,2, it comprise integral type fixing frame 1, many groups to be arranged on fixing frame 1 orientable flexible flexible supporting frames 2 and the columniform roller 3 of many groups.Many groups roller 3 passes through the tangent formation of flexible supporting frames 2 by the confined space of running shaft 5 fixed support.Often organize in the inner diameter hole 3.1 of roller 3 and be all provided with locating stud 4 and can roll around locating stud 4, one end of locating stud 4 is provided with bending part 4.1, and the other end of locating stud 4 connects with corresponding one group of flexible supporting frames 2.
Flexible supporting frames 2 shown in Fig. 1 comprises connecting rod 2.1, flexible rod 2.2 and spring 2.3.The two ends of connecting rod 2.1 are connected with locating stud 4 and flexible rod 2.2 respectively, and flexible rod 2.2 passes fixing frame 1, and on flexible rod 2.2, install the upper limit nut 2.4 and lower position nut 2.5 of avoiding its disengaging fixing frame 1.Spring 2.3 is enclosed within flexible rod 2.2, the two ends of spring 2.3 respectively with the interior side contacts of upper limit nut 2.4 and fixing frame 1, lower position nut 2.5 is positioned at the outside of fixing frame 1.Fixing frame 1 has guiding groove 1.1, be provided with in guiding groove 1.1 and can only stretch on fixing frame 1 and the positioning bolt 1.2 that can not rotate for flexible supporting frames 2.Connecting rod 2.1 is fixedly connected with by fastening screw trip bolt 2.6 with flexible rod 2.2.Roller 3 is provided with three groups, and flexible supporting frames 2 is also three groups, and the adjacent expansion bar 2.2 of three groups of flexible supporting frames 2 is mutually in 120 degree of angles.
Working procedure of the present utility model:
Measure-alike three groups of rollers 3 are connected with corresponding one group of flexible supporting frames 2 respectively by locating stud 4, and the external diameter of locating stud 4 is slightly less than the internal diameter of roller 3, and roller 3 freely can be rotated on locating stud 4, flexible supporting frames 2 be connected with fixing frame 1 respectively.During use, push three groups of flexible supporting frames 2 open by external force, make flexible rod 2.2 retracted downward, three groups of rollers 3 can be outwards mobile with flexible rod 2.2, opened by the confined space of supporting rotating shaft 5, is convenient to be wound around silk thread from the feeding in flexible supporting frames 2 external world with pass through; After running shaft 5 puts in place, remove external force, flexible rod 2.2 can protrude upward under the effect of spring 2.3, and three groups of rollers 3 can automatically reset with flexible rod 2.2, and closed confined space, fixes running shaft 5.
The extrusion adjusting the flexible rod 2.2 of three groups of flexible supporting frames 2 is identical, and three groups of rollers 3 can be automatically tangent in a free state, and the cylndrical surface of three tangent rollers 3 can form an enclosed space.According to the external diameter of running shaft 5 select the roller 3 of correspondingly-sized can make running shaft 5 and three rollers 3 all tangent.Because three tangent rollers 3 just can offset the active force of flexible supporting frames 2 upper spring 2.3, therefore, running shaft 5 can not be subject to the extruding of roller 3, but can be spacing and can not offset in rotary course by three point of contacts.
By selecting the spring 2.3 of different elastic force, the dynamics size that support opened by flexible rod 2.2 can be adjusted; Utilize many group flexible supporting frames 2, the support of overlength running shaft 5 can be realized; Adopt multicomponent to found flexible supporting frames 2 and coordinate supporting rotating shaft 5, flexible supporting frames 2 and roller 3 follow running shaft 5 automatically, and allow running shaft 5 to bend within the specific limits, the support that can realize non-rectilinear running shaft 5 is fixed.
