Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, Fig. 2, comprise guide holder 1, straight pin 2, flexible pin 3, dust ring 4, stop pin 5, gag lever post 6, jacking mechanism 7, carriage 7-1, spring 7-2, steel ball 7-3, eccentric finger 8, vertical through holes 9, transverse holes 10, stopper slot 11, link slot 12, bar-shaped trough 13, V-shaped groove 14 etc.
As shown in Figure 1, 2, the present invention is a kind of eccentric driving lever retractable pin mechanism, comprise a guide holder 1, on described guide holder 1, offer vertical through holes 9 and be communicated with the transverse holes 10 of described vertical through holes 9, in described vertical through holes 9, be provided with flexible pin 3, be provided with eccentric finger 8 in transverse holes 10, eccentric finger 8 leading sections are fixed with straight pin 2, described straight pin 2 front ends stretch in flexible pin 3 lower surface link slots 12, and the axis of the eccentric finger 8 of the axis runout of straight pin 2.
Described flexible pin 3 top peripheries offer bar-shaped trough 13, on guide holder 1, be provided with the stop pin 5 that prevents that flexible pin 3 from rotating, described stop pin 5 front ends stretch in bar-shaped trough 13, and stretch into the width of the shank in bar-shaped trough 13 and the width that bar-shaped trough 13 is slightly less than bar-shaped trough 13.
On described eccentric finger 8 peripheries, offer a circle stopper slot 11, on guide holder 1, corresponding to described stopper slot 11 places, be provided with gag lever post 6, described gag lever post 6 lower ends are stretched in stopper slot 11.
On described eccentric finger 8 peripheries, also offer V-type groove 14, on guide holder 1, corresponding to described V-type groove 14 places, be provided with jacking mechanism 7, described jacking mechanism 7 bottoms fit on the groove face of V-type groove 14.
Described jacking mechanism 7 comprises carriage 7-1, spring 7-2, steel ball 7-3, wherein carriage 7-1 swelling is on guide holder 1, steel ball 7-3 is placed on V-type groove 14, and spring 7-2 is placed in described carriage 7-1, and spring 7-2 two ends hold out against respectively in steel ball 7-3 and carriage 7-1 inside top surface.
Between flexible pin 3 tops of product of the present invention and vertical through holes 9, be provided with dust ring 4, between eccentric finger 8 outer ends and transverse holes 10, be also provided with dust ring.
The course of work of the present invention is as follows: product of the present invention is when design, what must note is a bit that straight pin 2 is at the axial eccentric position place of being fixed on eccentric finger 8, when operation is used, by inner hexagon spanner, rotate eccentric finger 8, straight pin 2 circles under eccentric finger 8 drives, because straight pin 2 front ends are connected on flexible pin 3, therefore flexible pin 3 is done oscilaltion campaign vertical through holes 9 is interior under straight pin 2 drives, between the highs and lows of straight pin 2 circular motion, distance is flexible 3 the activity of selling; In order to prevent flexible pin 3 phenomenon that rotates in elevating movement process, this product also special design stop pin 5, flexible pin 3 is carried out to axial location, avoid flexible pin 3 to rotate; Simultaneously in order to prevent that eccentric finger 8 is in the situation of the interior generation axial float of transverse holes 10, this product also special design gag lever post 6, to guarantee that eccentric finger 8 can only rotate, and can not produce the problem of axial float; The stopper slot 11 of eccentric finger 8 is half-arc groove, and the rotation angle range of eccentric finger 8 is exactly the angular range of stopper slot 11 circular arcs.Also be designed with jacking mechanism 7 for increasing the spin friction power of eccentric finger 8 simultaneously, make eccentric finger 8 be not easy to become flexible.
