Embodiment
Explanation and embodiment further illustrate to the utility model below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of micro- shape main axis of dilatation, including active spool 1, driven spool 6, the and of flange screw rod 2 manually
Dish shape nut 4, one end of the flange screw rod 2 are connected with the dish shape nut 4, and the other end of the flange screw rod 2 connects successively
The driven spool 6, active spool 4 are connect, the active spool 1, driven spool 6 fit, and the flange screw rod 2 is through described
Binding face between active spool 1, driven spool 6, the axis of the flange screw rod 2 and the active spool 1, driven spool 6
Between binding face between angle be acute angle, be provided with free gap between the driven spool 6, flange screw rod 5.
As shown in Figure 1 to Figure 3, the flange screw rod 2 is provided with location nut 3, the location nut 3 and the dish-shaped spiral shell
Mother 4 fits.
As shown in Figure 1 to Figure 3, the flange screw rod 2 is provided with plain cushion 5, the plain cushion 5 be folded in the location nut 3,
Between driven spool 6.
As shown in Figure 1 to Figure 3, the active spool 1 is provided with the first inclined-plane, and it is oblique that the driven spool 6 is provided with second
Face, first inclined-plane, the second inclined-plane fit, and the driven spool 6 is located on the active spool 1, the flange spiral shell
Bar 2 is arranged on the driven spool 6.
As shown in Figure 1 to Figure 3, the active spool 1 is provided with the screwed hole coordinated with the screw thread of flange screw rod 2.
As shown in Figure 1 to Figure 3, the active spool 1, the fitting of driven spool 6 form cylinder.
As shown in Figure 1 to Figure 3, the driven spool 1 is provided with ellipse hole, and the flange screw rod 2 passes through described ellipse
Manhole is threadedly coupled with the active spool 6.
A kind of micro- shape main axis of dilatation manually provided by the utility model, is divided into two by spool（It is master and slave）Tilt complementary 360
Semicylinder with guide groove in degree, i.e. active spool 1, driven spool 6, and pass through driven spool 6 using a root flange screw rod 2
（Driven spool has an ellipse hole）, after being interlocked afterwards with plain cushion 5 and location nut 3 and dish shape nut 4, screw in and actively roll up
In the concentric screw of axle 1, disengaging displacement and profit are produced to drive driven spool 6 to prolong guide groove twisting dish shape nut 4 using external force
Glide to reaching later with effective clearance and ellipse hole and unclamp driven spool 6, have coiled strip and winding master file between centers enough
Gap, to reach the purpose that coiled strip easily takes out.Production efficiency is improved simultaneously, increases the stability of board, is reduced shared during expansion
Space, increase the winding space of coiled strip and improve the inconsistent situation of winding radius, reduce the area that board takes hall space,
This mechanism is applied to more small-sized coiled strip winding and unreeling structure more.
A kind of micro- shape main axis of dilatation manually provided by the utility model has advantages below：
1：Active spool 1, driven spool 6 form a right cylinder after locking, and make wound material will not therefore preceding mechanism
Because of spool, to prolong radius that axle center taken different and formed in the presence of extraneous driving force for the formed elliptical profile main shaft of combination
Irregular coiled strip, and less stable and the material that may make to conform in coiled strip produce fold or bumps occur not in operation
Flat phenomenon, influence to use quality, increase material damage, produce unnecessary economic loss.
2：Uncaged screw rod using dish shape nut 4, can be firmly uniform, it is easily operated, expansion and reduce it is convenient.
3：Fetch coiled strip efficiency high.
4：It is small to take bin installation site, improves effective utilization space.
5：The winding dynamics of external world's transmission can be more balanced.
6：Coiled strip displaced position is easy to adjust, fast.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
